THE NEW MANUAL - WHAT IS NEW?
This NEW Restaurant Systems Manual carries a new part number, 20150, for it
is a combining of the two previous manuals, KP Manual PN 12385 rev. "A" and ZD
Manual PN 16640. The combining of the two manuals does not eliminate any of the
limitations of system requirements of the original two manuals, but strives to organize
the information into a comprehensive order with additional informative information for
greater clarity and understanding.
Some of the changes you will notice in the new manual are made to reduce cost
of inventory, printing, manufacturing, ordering and returns. The first item you will notice
is the change in nomenclature, KP 375 or ZD 375 Agent Cylinder Assemblies are now
referred to as a Model 375 Agent Cylinder Assemble. Now there is only one part
number per Model of Agent Cylinder Assembly. No longer do you have to order a
different part number for a KP or ZD Agent Cylinder Assembly nor do you have to stock
two cylinders the same size simply because one is for a KP system and one is for a ZD
system.
Closer examination of the new manual will reveal that the original configured
MRM required that you purchase a MRM and an enclosure (painted or stainless steel)
separately. The new MRM Ills supplied pre-installed in an enclosure (painted or
stainless steel) ready to mount on the wall. The new MRM II incorporates the use of a
new ratcheting take up for the automatic detection line. The original MRM used a
manual take up method for the cable tensioning and was part number 11977. The
original MRM version is no longer in production, however if a replacement for an
existing unit is needed or if you are ordering a "Cabinet" enclosure (PN 11978) you can
still order part number 11977 as a replacement or to use in the "Cabinet" enclosure.
The part number now supplies a MRM II unit without the enclosure, but with the new
ratcheting take up. It is 100% interchangeable with the original MRM.
The new manual will still contain service and maintenance instructions for the
original style MRM. Anytime you see a heading that says MRM, it is referring to the
original style unit. If the information is good for both style units it will say MRM I MRM ll
The following arrangement, MRM / MRM II / PRM, indicates that the information is good
for all three units.
Due to the combining of the two manuals the following substitutions should be
used as follows:
KP Manual PN 12385 is superseded by Restaurant Manual PN 20150
ZD Manual PN 16640 is superseded by Restaurant Manual PN 20150
ZD 275 Agent Cyl. Asy. PN 17102 is superseded by Model 275 Agent Cyl. Asy PN 16921
ZD 375 Agent Cyl. Asy. PN 16650 is superseded by Model 375 Agent Cyl. Asy PN 13334
ZD 475 Agent Cyl. Asy. PN 17474 is superseded by Model 475 Agent Cyl. Asy PN 17397
KP/ZD 375 Mounting Bracket PN 16085 is superseded by 375 Mounting Bracket PN 17690

Amerex Restaurant Fire Suppression System (EX4658)
GENERAL INFORMATION
The Amerex KP I ZD Series Restaurant Wet Chemical Fire Suppression System is designed and has been
tested to provide fire protection for commercial cooking operations covering the hood, ducts, plenum and
appliances. Amerex Restaurant Fire Suppression Systems are a pre-engineered type as defined in NFPA
17A - Standard for Wet Chemical Extinguishing Systems. It is manufactured by the Amerex Corporation,
Trussville, Alabama.
It is essential that all installations of the Amerex KP I ZD Series Systems be performed in compliance with this
manual. Those individuals responsible for the design, installation, operation and maintenance of the
Amerex Restaurant Fire Suppression System must be trained by Amerex and hold a current Amerex
Certificate. All piping limitations, nozzle coverages, detector placements, etc. have been proven and
established through exhaustive testing by Underwriters Laboratories, Inc. Use of components other than
those referenced in this manual, or installations exceeding limitations stated in this manual will void all of the
Amerex KP / ZD Series System listings.
LISTINGS:
The Amerex KP I ZD Series Fire Suppression Systems are a listed pre-engineered fire extinguishing systems.
The KP & ZD systems are listed with Underwriters Laboratories, Inc. - USA per UL 300 fire test specification;
Underwriters Laboratories of Canada, Inc. per ULC/ORD 1254.6 - 1995 and Loss Prevention Certification
Board - UK per LPS 1223 rev. B. Testing required for listings under these standards involve live fire tests
under specific conditions involving commercial kitchen hoods, ducts and appliances. Each test fire is allowed
to reach its maximum intensity before agent is discharged. Each test was repeated using both maximum and
minimum piping, variations in agent storage cylinder pressure to simulate maximum and minimum
temperature ratings. Duct fire tests were extinguished with fans off and fans on; dampers open and closed.
Splash tests for various appliances were conducted to assure that discharge of the agent would not cause
excessive splashing of hot grease to provide greater employee safety during commercial cooking operations.
UL Standard 300 introduces a series of tests by specifically addressing the use of high efficiency fryers,
ranges, woks and the unique fire extinguishing challenges that these appliances present.
DESIGN:
The Amerex KP Series Pre-Engineered Fire Suppression Systems consist of mechanical and electrical
components to be installed by an Authorized Factory Trained and Certified Amerex Restaurant Fire
Suppression Systems distributor. The system is composed of an Agent Cylinder/Discharge Valve charged
with Amerex Kitchen Wet Chemical Agent and a Mechanical Release Module (MRM or MRM II) or Pneumatic
Release Module (PRM). The quantity of detectors, fusible links, nozzles, corner pulleys, pulley tees and
manual pull stations will vary depending on kitchen design.
The system operates either automatically if actuated by a detector or manually if actuated by a manual pull
station. Upon system operation, energy sources for the cooking appliances are required to be shut off
immediately. Electrical shutdown devices or suitable gas valves are referenced in this manual. Other
equipment such as audible/visual signaling devices can be added where required.
The Amerex Restaurant Fire Suppression System suppresses fire in commercial cooking equipment by
spraying Amerex Wet Chemical Agent in a pre-determined manner onto cooking appliances and into exhaust
ducts, filters and plenum areas. The primary means of fire suppression is either by saponification of surface
grease or by cooling the surface of oils and hot metal surfaces with fine droplets of agent, reducing the
temperature of the oil and appliance below the auto-ignition point.
Upon system discharge, the exhaust fans should be left on to aid in dispersal of the liquid suppressant that
results in cooling the plenum and duct. Any integral make-up or supply air should be automatically shut off
along with all cooking appliances. Some local Authorities Having Jurisdiction require exhaust fans to be shut
down by the fire suppression system. Check local fire codes, AHJ and Department of Health in the specific
area that the system is being installed for special installation requirements.
The Amerex Restaurant Fire Suppression System agent storage cylinders and cartridge shall not be installed
in environments below 32° F or above 120° F (0° C to 49° C).
June 2011 Section 1 General Information Page 1 -2
Amerex Restaurant Fire Suppression System (EX 4658)
GENERAL INFORMATION - ZONE DEFENSE SYSTEM
The Amerex ZD Series Pre-Engineered System consists of mechanical and electrical components to be
installed by an Authorized Factory Trained and Certified Amerex Restaurant Fire Suppression Systems
distributor. The system is composed of an Agent Cylinder Assembly charged with Amerex Kitchen Wet
Chemical Agent and a Pneumatic Release Module (PRM) or an MRM, MRM II using a linear link detection
network.
The system operates either automatically, if actuated by a rupture in the pressurized thermal responsive
tubing or by the separation of a thermal link, or manually if actuated by a manual pull station. Upon system
operation, energy sources for the cooking appliances are required to be shut-off immediately. Electrical
shutdown devices or suitable gas valves are referenced in this manual. Other equipment such as
audible/visual signaling devices can be added where required.
The Amerex ZD and KP Series Systems use the same components and share the same UL Listings and
limits for the protection of the exhaust duct, plenum and dedicated appliance protection. They do not share
the same piping limitations or installation philosophy. This manual provides the unique limitations which apply
to a Zone Defense Fire Suppression System.
What is the basic difference between a KP and ZD System Philosophy?
The Amerex Zone Defense System was developed for the kitchen that changes out it's cooking appliances
frequently to accommodate the change in menu or cooks. The ZD System provides a detection system and
protection system which allows for the mcving and rearranging of appliances without changing the fire
suppression piping or detection device locations. This is accomplished by using a detection network that will
detect a fire no matter where it occurs under the hood and will extinguish cooking appliances located
anywhere under the hood, as long as they are inside the "Zone of Protection". Also the appliances must be
capable of being extinguished from overhead. Appliances such as upright broilers, salamanders, covered
tilting skillets, chain feed pizza ovens, etc. are all appliances that cannot be extinguished from overhead, but
require specific nozzles with specific aiming for the individual appliance. The use of a "back shelf" over
appliances also will block the application of agent from overhead nozzles and therefore requires the use of
"Dedicated Appliance Protection" for an appliance with a back shelf.
The Amerex Kitchen Protection Fire Suppression System differs from the ZD System in the manner in which it
protects appliances and detects a fire under the hood. The KP System uses individual "Dedicated Appliance
Protection" for each appliance under the hood, requiring protection. A choice of the fire detection method may
be a standard thermal link network or one of the two linear detection networks. (PRM or Linear Fusible Link).
The KP & ZD Series Systems have their distinct application use in the field of kitchen protection. They both
provide superior protection from the hazards of commercial cooking.

actuation pulls the cable connected to the mechanical gas valve causing it to close and stop the flow of gas.
GAS VALVE: A mechanical or electrical valve used to shut off the supply of gas to the cooking appliances
when the fire suppression system discharges. Such devices are required by NFPA 96 and are to be listed
with the system components. Gas valves must be manually reset.
GREASE: Rendered animal fat, vegetable shortening, vegetable oils or any combination thereof, which is
used for, or the result of, cooking and preparing food. Grease may be liberated and entrained in exhaust air
or may be visible as a liquid or a solid.
GREASE FILTER: A component of the grease vapor removal system that deflects the air and vapors passing
through it in a manner that causes the grease vapor concentration and/or condensation for the purpose of
collection, leaving the exiting air with a lower amount of combustible vapor.
GREASE TIGHT: constructed and performing in such a manner as not to permit the passage of grease
under normal cooking conditions.
HOOD: A device provided for a cooking appliance(s) to direct and capture grease-laden vapors and exhaust
gases, and constructed within the requirements of NFPA 96.
INPUT: An event monitored by the Mechanical Release Module (MRM or MRM II) or Pneumatic Release
Module, which causes a corresponding output(s). (Example: A detector senses fire [input] and the system
discharges [output] and trips the gas valve [output]).
INSPECTION: A "quick check" to give reasonable assurance that the system has not been tampered with
and is in a charged, operable condition.

acceptable to the AHJ (Authority Having Jurisdiction) and concerned with product evaluation, which maintains
periodic inspection of production of listed equipment or materials and whose listing states either that the
equipment or material meets appropriate standards or has been tested and found suitable for its use in the
specified manner. The listing may not be considered valid unless so labeled.
MAINTENANCE: A "thorough check" to give maximum assurance that the extinguishing system will operate
as intended. Design parameters should be closely examined for hazard changes since the last inspection,
parts and components should be closely examined and tested or replaced if necessary.
MAKE-UP AIR: Air that is brought into the hazard from outside of the area, using a dedicated fan, to aid in
the exhaust of grease-laden vapors.
MANUAL PULL STATION: The device that allows the system to be manually discharged either at the hazard
or from a remote location.
MECHANICAL RELEASE MODULE (MRM I MRM II): An assembly that connects and controls the actuation
cartridge, the detectors, the manual pull station(s), the gas valve, the micro-switch(es) and the agent
cylinder/discharge valve(s). It receives inputs and activates appropriate outputs - including agent release,
auxiliary signals and power or gas shut-off.
SNAP ACTION SWITCHES: A set of dry (unpowered) electrical contacts arranged in various configurations
for initiating appropriate output functions such as signal to the building fire alarm, audible/visual remote signal,
electrical power shut-off, electric gas valve shut-off.
NOZZLE: The device used to deliver a specific quantity, flow and discharge pattern of fire suppression agent
to a specific appliance, duct size or plenum size.
NOZZLE BRANCH LINE: All pipe and fittings leading from the supply branch tee to a system nozzle.
OUTPUT: An action that is initiated by the mechanical release module in responding to a pre-determined
input. (Examples: Agent release, power shut-off, remote signal, gas valve closure)
PERIMETER INCHES: The sum of the measurement of each side of a rectangular duct opening. (Example:
Duct opening measuring 18" x 9" would have 54 perimeter inches [18 + 18 + 9 + 9 = 54])
PLENUM: The space defined by the filters and the portion of the hood behind the filters.
PNEUMATIC RELEASE MODULE (PRM): This single hazard control mechanism supervises and controls
one Fire Suppression System. Proven, rugged mechanical components are reliably set into motion with a
simple linear pneumatic detection interface. The control mechanism interfaces with mechanical manual pull
station(s), actuation networks, mechanical gas valves, and offers electrical contacts for shutdown functions.
Refer to the Design and Installation Manual, P/N 16546 for further details.
PRE-ENGINEERED SYSTEM: Those systems having pre-determined flow rates, nozzle pressures and
quantities of agent. These systems have the specific pipe size, maximum and minimum pipe lengths, flexible
hose specifications, number or fittings and number of types of nozzles prescribed by a testing laboratory. The
hazards protected by pre-engineered systems are specifically limited as to type and size by a testing
laboratory based on actual fire tests. Limitations on hazards that can be protected by these systems are
contained in the manufacturer's installation manual, which is referenced as part of the listing.
"PUFF TEST" (or "AIR TEST"): A test to determine that the distribution network piping is clear. The test is
conducted by running nitrogen through the piping and confirming that all nozzles are clear.

SALAMANDER BROILER: See upright broiler.
SAPONIFICATION: The reaction of fats and/or oils to alkaline materials, producing soap-like foam. Fire
extinguishing agents based on sodium bicarbonate, potassium bicarbonate, potassium acetate and potassium
carbonate will cause saponification when discharged onto hot grease. Rendered animal fat and oils containing
high percentages of saturated fat saponify better than cooking oils containing low percentages of saturated fat.
SERIES DETECTOR: Any detector located between the Mechanical Release Module (MRM or MRM II) and
the terminal detector.
SUPPLY LINE: That portion of the agent distribution network piping that runs from the agent cylinder
assembly outlet or distributor block to the first tee.
SUPPLY BRANCH LINE: All pipe and fittings leaving the first tee in the system and ending with the last
nozzle in the last nozzle branch line.
TERMINAL DETECTOR: The last detector (or only detector) in the detection network. It is at this point that
the cable for the detection network ends or is terminated.
TEST LINK: This device is used in place of a fusible link in order to easily test the detection network. The test
link is easily cut, simulating a fusible link separating under fire conditions. It is usually located on the terminal
detector and is used solely for test purposes.
UPRIGHT BROILER: A cooking appliance using intense radiant heat and conductive heat with the foot and/or
the radiant heat source not being limited for a horizontal mode. Most of these cooking appliances incorporate
a removable drip tray and may be used specifically for holding or warming foods.
VENT CHECK: A device installed in the actuation network that is used to safely relieve pressure and to
prevent a slow, unwanted build-up of pressure in the actuation network.
ZONE of PROTECTION - A horizontal foot print below and within the perimeter of the hood, in which the
cooking appliances are to be positioned. The discharge nozzles within the "Zone of Protection" are spaced at
pre-determined intervals to provide protection for eligible appliances within the "Zone of Protection" without the
need for re-aiming or repositioning of nozzles. An exception to this practice is for dedicated appliances such
as the upright broiler. Dedicated appliances require appliances specific nozzles protection, which will require
further review after movement of the appliance for possible re-aiming or repositioning of nozzle(s).

MODEL 600 PNEUMATIC ACTUATOR (PIN 10147)
A pneumatic actuator is required for every KP600 Agent Cylinder
Assembly. The actuator is bolted directly to the top of the agent
cylinder discharge valve. When actuation occurs at the MRM /
MRM II or PRM, the pneumatic pressure from the nitrogen cylinder
enters the actuator through Y4"NPT threaded ports on either side.
The actuation pressure forces the piston inside to extend and
depress the valve stem of the discharge valve. The piston extends
through a retainer washer which allows a spring loaded ball plunger
to extend and lock the piston in its extended position. Resetting is
easier than the previous discontinued Actuator P/N15157.

PIN 18000: MRM II with Red-painted Steel Enclosure
PIN 18001: MRM II with Stainless Steel Enclosure
The new MRM II combines the same features and
functionality as the original MRM along with increased
detection capabilities and a far simpler means of
setting the detection cable tension. The MRM II is
available in the above configurations, now pre-
installed in its own enclosure.
The method of setting the detection cable tension on
the MRM II does not require the use of any tools (once
the cable is locked down into the large, knurled wind-
up spool). A large lever to the right of the spool is
used to increase the cable tension. Alignment of the
bottom edge of the lever with markings on a label on
the mounting plate indicates when the proper tension
has been achieved. In addition to being easier to set
up, lowering cable tension to change out detection
links is now also much simpler. The enclosure is 10"

MECEANICAL RELEASE MODULE II -(PIN 11S77)
WITHOUT AN ENCLOSURE
NOTE: This version of the MRM II is a direct replacement for
the old style MRM. It carries the same part number as the
origin.31 MRM.
The Mechanical Reease Module II is used to actuate the agent
cylinder discharge valve euler automatically or manually by
puncturing a nitrogen cylinder.
Automatic release cf agent is accomplshed when a fusible link
detector separates during a fire condition. This causes a spring-
loaded plunger to perforate the rupture disc and releases nitrogen
through the actuaticn hc.se/pioing network to the agent cylinder
discharge valve(s).
Manual release of agent is acccmplished by pul ing on a manual
pull station which is connected to the Mechanical Release Module
II by a cable.
The Mechanical Release Module II is equipped with two snap
action switches, one (PIN 12524) for electrical signaling, power
shutdown and other auxilary uncions and a second (P/N 18312)
alarm initiating snap action switch for connection to a fire alarm
panel. An additional wo snap action switches may be added.
Operation of one or two mechanical gas valves may be
accomplished by add ng a Gas Trip Assembly (P/N 12740).

AMEREX MECHANICAL GAS SHUT-OFF VALVE
All Amerex Kitchen Fire Suppression Systems protecting gas-fired cooking appliances must use a gas shut-
off valve listed for use with the system. The Amerex Mechanical Gas Valves are held open with a latching
device. Upon system discharge a piston in the MRM, MRM II or PRM will pull on a cable connected to the
latch in the gas valve actuation box, releasing the latch and allowing the gas valve spring to close the valve.
These valves are considered to be "Normally Closed - Held Open". The valve bodies are made of brass and
threaded with female NPT threads on both ends and are UL listed for natural gas and propane in 3/4", 1", 11/4',
1%", and 2" sizes. The Gas Trip Assembly PN12740 is included with all Amerex Gas Valves.

ELECTRIC GAS SHUT-OFF VALVES
Electric gas shut-off valves operate on 110 VAC
current which powers a solenoid holding the valve
open against a spring. Upon system discharge
current to the solenoid is interrupted by a micro switch
in the MRM, MRM II or PRM causing the valve to shut.
A loss of electrical power will also cause an electrical
gas valve to close. A Manual Reset Relay must be
used with each electric gas valves. UL listed sizes are 3/4, 1", 1 1/4, 11/2", 2", 3".
MANUAL RESET RELAY (PIN 12526)
Anytime an electrical gas valve is connected to an Amerex Kitchen Fire
Suppression System, a Manual Reset Relay must be used. After an
electrical gas valve has closed (either because of system discharge or
because of power failure), the gas valve cannot be opened without
manually pressing the reset button on the Manual Reset Relay. This
operation is to guard against a momentary loss of power closing the valve,
extinguishing the pilot lights and allowing gas to escape when power is
restored. The Manual Reset Relay is UL listed and has a pilot lamp to
indicate its status.

FIGURE 1 FIGURE 2
Figure 1 is an illustration of a large tilting skillet measuring 26" x 48" and the tilting skillet has no drip
board. We calculate the cooking area of the tilting skillet by multiplying the width X length and the
result is 1248 sq. in. We now divide the area by the listed area of 624 and the resultant is 2.
Therefore, two nozzles are required to protect this appliance. (If the resultant had been greater than 2,
we would have rounded up to 3.
Figure 2 shows how the hazard was divided into two equal modules 26" x 24" and each module has
an area of 624 sq. in. Therefore, the use of two nozzles P/N13729 will protect this hazard. When
protecting a tilting skillet with a cover or lid the nozzles must be placed to the front edge of the
appliance and aimed to the center of the module.
The same process is to be used to apply this listing to a large fryer except the fryer must fall within the
required maximum fryer size of six square feet.

NIECO MODEL 9025 - BURGER KING CHAIN BROILER
TWO - SINGLE FLOW POINT NOZZLE (P/N 11982)
The Nieco Chain Broiler Model 9025 is a unique appliance and when fitted with two catalysts it requires the
use of two Amerex nozzles (P/N11982) to protect each half of the appliance. Total appliance protection
therefore, requires the use of a total of four Amerex nozzles (PIN 11982). This unique appliance is actually
two chain broilers put together to accommodate the cooking of two different products at the same time. This
appliance can be fitted with two catalysts (18" x 24" overall) one for each cooking side.
The protection of the appliance is accomplished by using two nozzles P/N 11982 positioned two inches
outside of the catalyst perimeter aimed at the center point of the catalyst. The nozzles are to be located on
opposite ends of the catalyst, 1800 apart and are to be 13" to 36" above the top surface of the catalyst. This
configuration is repeated for both cooking sides of the appliance. If no catalyst is used the same protection is
required for the unit.
Note: Maximum & minimum heights
must be measured from the tip of nozzle
to the top surface of the catalyst or
appliance (if no catalyst is used).

DUKE CHAIN BROILER & DUKE HOOD EXHAUST HOOD
TWO -.TWO FLOW POINT NOZZLE (P/N 13729)
The Duke Chain Broiler and Hood combination is a special design just for the Duke product. The hood and
broiler are each fitted with a catalyst to decrease the emission of grease laden vapors into the exhaust duct
system. The hood comes pre-piped for the installation of the fire suppression nozzles. This unique appliance
operates at an extremely high temperature in order to cook large quantities of frozen burgers in a short span
of time.
The protection of this unit is accomplished by using two (2) Nozzles P/N 13729 installed in the piping provided
so that it will spray agent into the catalyst as illustrated. A third nozzle P/N 16416 is installed for duct
protection of the 8" diameter exhaust duct.
If no catalyst is used the same protection is required. The addition of a damper on top of the broiler catalyst
does not change the protection required for the unit. Due to the extreme heat of the appliance close
inspection of the nozzles is to be performed at each six month service interval. Nozzle replacement is
required at the signs of any nozzle deterioration.

Amerex Restaurant Fire Suppression System (EX 4658)
Back shelf— What to do?
The use of a back-shelf presents a problem to the designer of a kitchen fire suppression system for it is
an impediment to the delivery of the wet chemical to the potential fire hazard. The same is true for
salamanders that are mounted over an appliance requiring protection. A shelf or salamander that
extends over the appliance not only prevents proper delivery of wet chemical but also is a fire hazard. All
too often, these shelves become storage places for items such as paper plates, doggie bags, or
flammable food preparation liquids. The overhead application of the wet chemical from an Amerex
Restaurant Fire Suppression System would be of help in extinguishing a fire occurring in items placed on
a back-shelf, but that is not the intended hazard for which the system was designed. The shelf or
salamander prevents agent, from an overhead nozzle, from reaching the actual cause of fire in the
appliance.
Amerex has developed the only real world solution to this problem. When a shelf is installed over a
range or a griddle, a small manifold of three special nozzles provides fire suppression protection. The
BSM (back-shelf manifold) is designed to function as supplemental agent application for the area under
the back-shelf. It replaces the agent lost because of the shelf. It provides an area of protection 15" deep
and 42" wide when used over a range.
The back-shelf or salamander can extend 1" beyond the centerline of the appliance with the manifold
nozzle tips located 14" to 19" above the appliance. The first nozzle must be placed ½" outside the edge
of the hazard and on the centerline of the hazard area covered by the shelf.

BSM: Back Shelf Manifold Asy. - (PIN 17461 with nozzles)
The BSM (P/N 17461) is comprised of three Amerex nozzles, positioned on a 450 angle and
spaced 12" apart. All nozzles are in the same plane of alignment and at the same height. This is
accomplished by the use of the Amerex manufactured manifold. The manifold is constructed from a
custom aluminum extrusion which is machined to the precise requirements needed to maintain
proper alignment of the nozzles. Connection to the nozzle branch piping may be made from either
end of the assembly. The opposite end of the assembly is to be plugged with a 3/8" pipe plug. The
manifold should appear as illustrated.
I I \ L L 'J V V I I N I I N NJ L L. L L NJ
The BSM is to be used as an assembly of three nozzles and will carry a flow point value of one (1).
It is designed to extinguish fires located under the back shelf when they occur on the back three
burners of a six-burner range (15" x 42") or the back portion of a griddle. It never takes the place of
the overhead nozzle, but simply provides additional agent to extinguish any and all fires beneath
the back shelf or salamander.
The same limitations apply to salamanders that are applied to back shelves.
When the BSM is used to protect a griddle positioned under a back shelf, the manifold is installed
on the centerline of the portion of the griddle covered by the back shelf or salamander. The
maximum amount of back shelf coverage allowed for griddles is 16". The location of the overhead
nozzle is always to be to the front edge of the griddle. See required nozzle and aiming
requirements on the next pages for details on griddle protection.
The following pages are examples of manifold placement under several conditions of back shelf
use. The following schematics represent the only nozzle combinations permitted with a BSM.
Note: When using the BSM assembly for range protection only the Range Nozzle (14178) is
permitted in the overhead protection position as indicated on the schematics.

The schematic above shows the protection method on two different size griddles (30"x42" & 30"x48") that
are positioned under a back-shelf. Note that the shelf extends 1" beyond the center of the griddle (16")
and covers the entire width of the griddle, all which are withir the parameters of the listing. Also,
recognize that the centerlines of the manifolds are congruent with the centerline of the hazard covered by
the back-shelf. Each manifold must be located on the centerline of the hazard area it is to protect.
The P1N16416 nozzle plus a BSM (back-shelf manifold) will protect griddles up to 30"x42" maximum, with
a back-shelf that covers no more than 16" of gridde. Total flow point value is 2 flow points. The
overhead nozzle must be located on the front edge of the griddle aimed at a point 7" back from the center
of the hazard area on a straight line from the nozzle to the center of the hazard.
The P1N14178 nozzle plus a BSM (back-shelf manifold) wil protect griddles up to 30"x48" maximum, with
a back-shelf that covers no more than 16" of griddle. Total flow point value is 3 flow points. The
overhead nozzle must be located on the front edge of the griddle aimed at a point where a straight line
from the nozzle to the center of the griddle crosses an 11" square placed over the center of the griddle.

SPOT DETECTION NETWORK LIMITATIONS: MRM & MRM II
Optimum fire suppression system performance relies on proper detection network design. This section
discusses the type of detectors used, their selection, and placement and design limitations.
The Amerex Restaurant Fire Suppressior System MRM & MRM II uses a continuous cable, corner pulleys,
detector bracket, detector linkage, fusible links, conduit offset, terminal link connector and a temperature-
measuring device.
The quantity of detectors to be used in a system will depend on the number of ducts, number of appliances and
the location of the appliances under the hood.
DETERMINING SPOT DETECTOR LOCATION AND NUMBER OF DETECTORS
In order to detect a fire in the duct, a detector is required to be placed within the duct opening or up to 12 inches
into the duct. If it is mounted into the duct, the bracket shall not shield the fusible link from the hot vapors
moving through the duct.
Every appliance under the hood that is being
protected by the suppression system must
have a detector placed over it and
positioned within the path of exhaust vapors.
WARNING: DO NOT LOCATE DETECTORS
DIRECTLY IN THE PATH OF GAS APPLIANCE
EXHAUST FLUE GASES. DOING SO COULD
RESULT IN UNNECESSARY DISCHARGE OF

GENERAL LIMITATIONS OF DETECTION NETWORK:
Maximum of 30 corner pulleys. (either style)
Maximum of 30 detectors (any combination of temperature settings).
Maximum of 200 feet of cable on the detection network.
No pulley tees are allowed.
Remote manual pulls are not allowed on the detection network.

LINEAR FUSIBLE LINK DETECTION NETWORK OF SPOT DETECTORS
The standard spot detection system may be installed in a manner that will yield linear detection for the entire
length of the hood without concern for where the appliance is located under the hood.
Why would I use this method over the lanyard linear fusible link system?
You want linear detection for the full length of hood but the limit of twenty links is not enough for the
length of hood being protected.
You are protecting two hood and they are back to back, the lanyard system must be installed in a
straight tine.
You have two hoods that are end to end but one of the hoods only has one appliance requiring
protection. The lanyard system is used for total linear detection of the entire hood. This version of
detection allows you to use total linear hood detection on one hood and spot detection on the
second hood.
This is accomplished by installing the link brackets so that there is a link no more than 24" from each end of the
hood and no more than 24" between each successive link center. You must locate one link in the hood / duct
opening.
The limitations on the amount of cable and links that can be used in the system are the same as that for the
standard spot detection system.
Limitations: Maximum of 30 corner pulleys. (Either style)
Maximum of 30 detectors (any combination of temperature settings)
Maximum of 200 feet of cable in the detection network.
No Tee Pulleys are allowed
Remote manual pulls are not allowed on the detection network.

The Linear Fusible Link Detection System provides complete hood fire detection by placing thermal
links at maximum 24" intervals the entire length of the hood. Installing the links in this manner allows
the appliances to be placed anywhere under the hood without having to locate links directly over each
appliance.
A unique system of cable segments, pre-fabricated, has been developed to make tte installation of
this system simple and easy. It eliminates the use of conduit, link holders and mounting brackets
under the hood in the plenum area.
The limitations of the Linear Fusible Link Detection System are as follows:
Maximum of 20 detection links and (19) Link to Link Cable Segments.
Maximum of 30 feet of cable used in the Link to MRM Cable Segment.
Maximum of 20 corner pulleys. (either style)
Maximum unsupported detection cable length is 8'-0".
Refer to Fusible Link Selection section, page 3-24 of this manual for proper selection process
The higher setting links are to be used when higher temperatures are encountered with
appliances such as char-broilers.
The Linear Fusible Link Detection System is for use in single hood applications, .r where
multiple hoods are connected "eid to end" only. It cannot be used for "back to back" hood
arrangements or multiple hoods that are mounted in separate locations and are part of a
single Restaurant Fire Suppression System.
December 2008 Section 3 KP Design Page 3 - 37
Amerex Restaurant Fire Suppression System (EX 4658)
FUSIBLE LINK SELECTION
To assure that the appropriate temperature is selected, the temperature sensing device must be used at each
detector location while the cooking line and exhaust fan is operating. Temperatures found at each detector
should be recorded and placed with other documentation in the job file for future reference. Selection of fusible
links should be made according to the temperature measured:

MECHANICAL GAS VALVE APPLICATIONS
The MRM, MRM II or PRM closes the mechanical gas valve immediately upon system discharge. A pneumatic
and mechanical action in the gas trip assembly pulls on a cable attached to the mechanical gas valve,
unlatching the valve and allowing an internal spring within the gas valve body to provide the closing force.
Connection of the cable from the gas valve to the MRM, MRM II or FRM under tension maintains the gas valve
in an open position.
MECHANICAL GAS VALVE
A mechanical gas valve trip assembly must be used
with any mechanical gas valve. The gas valve trip
assembly (P/N 12740) is included with all Amerex
manufactured gas valves but must be ordered
separately. for use with gas valves listed in this AMEREX PAR7 NO. 12740
manual supplied by other manufacturers.
See Section 3 "System Components" for all mechanical gas valves that are suitable
for use with the Amerex Restaurant Fire Suppression System. The use of any other
mechanical gas valves will avoid the UL listing for the system installation. All of the
listed valves have female NPT threads. The location of the gas valve should be
accessible and approved by the local Authority Having Jurisdictior:. A contractor
licensed and qualified for such work should perform installation of the mechanical gas
valve into the gas line.
MECHANICAL GAS VALVE ACTUATION NETWORK LIMITATIONS
—— 1.
The mechanical gas valve actuation network consists of cable, corner pulleys, pulley tee, gas valve and conduit

ELECTRIC GAS VALVE OPERATION
Power to the electric gas valve is run through the normally closed contact on a micro-switch located in the
Pneumatic Release Module (PRM) or Mechanical Release Module (MRM & MRM II) to the Manual Reset Relay
and from the Manual Reset Relay to the electric gas valve. In a normal (non fire) condition, current is allowed to
flow to the solenoid on the electric gas valve, holding the valve open. In a fire condition, when the release
module actuates the suppression system, the micro-switch contacts will transfer, opening the normally closed
contacts in the manual reset relay, interrupting current to the gas valve and cause it to close.
Resetting the MRM, MRM II or PRM and transferring the contacts back to a normal (normally closed) position
will not cause the electrical gas valve to open. The manual reset relay must be reset before current will flow to
the valve and cause it to open. A loss in electrical power, even temporary or momentary, will require someone
to manually reset the relay before the electrical gas valve will open again.

NFPA 96— 10.1.1: "Cooking equipment that produces grease-laden vapors and that might be a
source of ignition of grease in the hood, grease removal device, or duct shall be protected by fire-
extinguishing equipment."
The Amerex "Zone Defense" Fire Suppression System has been approved and tested in compliance with
the requirements of NFPA 96 - "Standard for Ventilation Control & Fire Protection of Commercial Cooking
Operations, NFPA 17A - "Standard for Wet Chemical Extinguishing System" and UL-300 - "Fire Testing of
Fire Extinguishing Systems for Protection of Restaurant Cooking Areas". The Amerex "Zone Defense"
System provides two types of appliance protection; "Zone of Protection" and "Dedicated Appliance

ZONE OF PROTECTION - DEFINED
The "Zone of Protection" is a rectangular area 34" deep X the length of the hood in which an eligible
cooking appliance can be placed and be protection. The appliance may be moved to any location within the
"Zone of Protection" and be protected without any nozzles being moved or re-aimed.
The "Zone of Protection" is created by the use of overlapping spray from multiple nozzles creating an area
that is soaked by wet chemical agent. This is accomplished by placing Amerex ZD nozzles, part number
14178, in a straight line from one end of the hood to the opposite end. The nozzles are to be a maximum of
20 inches (50.8cm) apart on center and must start and end at a point no greater than 6 inches (15.2cm)
from the end of the hood. The nozzles are to be located 46 to 51 inches above the top surface of the
appliances and aimed straight down. The resulting "Zone of Protection" is a rectangular area 34" (86.4cm)
deep x length of hood with its front and rear edges 17" (43.2cm) from the centerline of the nozzles.

ZONE OF PROTECTION - CONT.
The 'Zone of Protection" requires that the nozzles be placed at 46 to 51 inches above the top surface of the
appliance, all ZD nozzles are to be placed at the same elevation and the nozzles are to be aimed straight
down. No additional aiming is required because the eligible appliances are protected no matter where they
are located within the "Zone of Protection". Therefore, the spray is not to be impeded in any manner.
When an appliance such as an upright broiler or salamander is part of the cooking appliance lineup, a
dedicated appliance nozzle must be used to protect it. The ZD nozzles cannot protect cooking appliances with
an enclosed cooking area such as an upright broiler or salamander. No ZD nozzles are required above the
upright broiler protected by a dedicated nozzle, however the ZD nozzle located to the right and left of
the appliance must be no more than 6 inches from the edge of the appliance. The illustration below
reflects the situation described above. The location of the upright broiler is now fixed and the appliance must
remain in this location.
Dedicated appliance protection of salamanders, cheese melters, chain broiler or a range with a back-shelf is
always in addition to the zone defense nozzles located overhead.

DETECTION NETWORK LIMITATIONS:
PRM DETECTION
Optimum fire suppression system performance relies on proper detection network design. This section
discusses the location, design and instalation limitations.
The Amerex Zone Defense Fire Suppression System may use one of two detection methods. The first is a
PRM that uses a continuous piece of pressurized thermal sensitive tubing to provide the ultimate in
dependable fire detection. No cable, No corner pulleys, No detector bracket, No link holders, No fusible
links, No conduit offset, or terminal link connector to install. Simply run the pressurized thermal sensitive
tubing through the plenum of the hood and across the center of the hood duct opening. Fasten the tubing
securely every 18 inches (45.7cm) and you have provided protection the entire length of the hood. No matter
where the appliance is located under the hood, it is being watched by the PRM (Pneumatic Release Module).
In order to detect a fire in the duct, the tubing is required to be placed across the center of the hood / duct
opening or three sides of the hood duct opening. See page 4-5 of the manual for tubing routing and see PRM
Design & Installation Manual Part No. 16546, dated, March 2006, for installation instructions.
WARNING: DO NOT LOCATE TUBING DIRECTLY IN THE PATH OF GAS APPLIANCE EXHAUST FLUE GASES.
DOING SO COULD RESULT IN AN UNNECESSARY DISCHARGE OF THE SYSTEM.

MRM & LINEAR FUSIBLE LINK DETECTION
The second detection method is the use of a MRM or MRM II in conjunction with the Linear Fusible Link
Detection network. Due to the arrangement of the fusible links in the hood it is considered to cover the full
length of the hood, no matter where the fire may occur. This system is explained in Section 3, page 3-35 & 3-

A pneumatic actuator is required for every KP600 agent
cylinder assembly. The actuator is bolted directly to the top of
the agent cylinder discharge valve. When actuation occurs at
the MRM or PRM, the pneumatic pressure from the nitrogen
cylinder enters the actuator through 1/4U NPT threaded ports on
either side. The actuation pressure forces the piston inside to
extend and depress the valve stem of the discharge valve.
The piston extends through a retainer plate and the ball
plunger locks the piston in its extended position.

Tubing may be cut down to the required length with the use of Cutting Tool P/N 16860, or be coiled up and
secured with wire ties outside the hazard area. Cuts must be square and clean. The minimum bend radius is
6 inches (15.2cm). Do not crimp or crush the tubing in the course of handling or installation. A Tubing Clip
(PN 16501) is to be use to secure the tubing every 18" (45.7cm). A Tubing Clip is also required within one
inch of the End of Line Fitting. The tubing can exit the enclosure ,either through the 5/8" hole at the upper right
hand corner of the enclosure (where a strain relief fitting is installed at factory), or it can exit through the 5/8"
hole at the top right of the enclosure. If it is desired to route it through the top, switch the strain relief fitting
with the snap-in plug.

detection tubing.
TUBING SPACING & ROUTING - PRM
The detection tubing is to be run at the top of the plenum, behind the filters from one end of the plenum to the
opposite end to ensure total detection coverage. Ensure that the tubing is routed in such a way as not to
interfere with any moving parts or access openings. Tubing must not be obscured by structural or support
structures, and should be fully exposed to any rising hot gasses from the cooking media, to ensure rapid
detection response. Terminate the tubing within 6" (15.2cm) of the end of the plenum. Refer to page 4-7 for
proper end of line installation. The tubing is never to be routed in the path of hot flue gases from a gas fired
appliance for this can result in a unwanted discharge. Never locate the tubing where the daily removal of the
filters will result in scraping or damaging the tubing surface for this too will result in an unwanted discharge.
Additionally, the detection tubing is to cross over the hood I duct opening in compliance with NFPA - 17A.
When the opening width exceeds the 18" (45.7cm) maximum mounting clip spacing, the tubing is to be
installed along at least three of the four sides of the hood / duct opening. See figure below:

SECURING THE TUBING - PRM
The tubing must be secured at a distance not to exceed 18" with PN16501 Tubing Clip. A Tubing Clip is also
required within one inch of the End of Line Fitting. Since the tubing snaps into the clip, it is recommended
that the clips be installed first, then the tubing. Ensure that the tubing is routed in such a way as not to
interfere with any moving parts or access openings. Tubing must not be obscured by structural or support
structures, and should be fully exposed to any rising hot gasses, to ensure rapid detection response. Never
take up slack by pulling the tubing through a series of clips, this action could damage the tubing and shorten
its useful life.

TUBING TERMINATION - PRM
Care must be taken when terminating the start and end of the tubing to ensure leak proof connections. Below
are the instructions for termination:
Remove knurled nut from plated tube fitting and slide over end of tubing. The end of the tubing must be
cut square and clean. DO NOT use pliers or wire cutters for cutting the tube. These tools will collapse the
end of the tubing and could create a leak point. The use of a sharp utility knife is suggested, while rolling the
tubing on a flat surface. Do not use any sealants on the connection.
Firmly push the end of the tube down over the end of the fitting. It may require working the tubing around
until it goes on (see following figure). It is important that the end of the tubing be inserted ALL the way over
the tip of the fitting. Hold the tubing in place firmly in one hand while tightening the nut with the other. Use a
12mm wrench (or adjustable) to tighten the nut. Resistance will be felt when the nut bottoms out. Do not over
tighten. The procedure is the same for both the accumulator cylinder fitting and the End of Line Fitting. It
may be helpful to place the End of Line Fitting in a small vise while terminating the tubing to it.
NO OAR
Once the system is pressurized and put into service (see below), both connections should be thoroughly
leak checked with leak check fluid or soapy water.
Record the date of tubing installation on the tubing replacement label and affix the label to the detection
accumulator cylinder.

INSTALLING THE DETECTION NETWORK - MRM or MRM II
Refer to the system design section for Detector Network limitations. There is only one type of detector
bracket and linkage used with this system. There are, however, two names for detectors in the network -
series and terminal. The terminal detector is the detector located at the end of the cable run, furthest away
from the MRM or MRM II. A series detector is any detector located in between the MRM or MRM II and the
terminal detector in the network.
Starting at one of the corresponding knock-out found on one of the two available sides (top or bottom) of the
MRM or MRM II. Install %" EMT conduit running from the MRM or MRM II to each detector location, using a
corner pulley at every change in direction. Each detector must be securely fastened to a rigid surface,
located over each protected appliance and in the hood / duct opening. Refer to the Design section for
limitations and cautions regarding detector placement.
To install the cable, start at the terminal detector, affix
the Cable with a terminal clamp (P/N 12859 provided
with the MRM & MRM II) leaving a minimum of 6
inches between the end of the cable and the terminal
clamp. From the terminal detector, continue to feed the
cable through each corner pulley, detector and length
of EMT conduit back to the MRM.

Setting Detection Cable Tension, New MRM II (PIN 18000 and 18001):
Refer to the following images in this section for properly setting the detection cable tension:
To set the tension on the cable, first make sure that the tension bar in the MRM II is in the "down" position
and that the spring is relaxed. Lower the top hook of the blue spring into the bottom of the tension bar slot.
Warning: Do NOT attempt to set the tension bar in the "up" position (spring stretched) without
having a fusible link line installed and secured or the MRM will fire. Take additional caution; DO NOT
install the Nitrogen Actuation Cylinder at this time.
Feed the cable end into the small hole in the side of the ratchet pulley. The end of the cable must be
cleanly cut. Push the cable into the hole until the end is visible at the head of the central hex-bolt. Securely
tighten the Allen-head set screw onto the cable. Aside from the use of the cocking tool, no further tools
should be used to set the mechanism. (The cable may be routed from either the bottom or the top of the MRM
II; the ratchet pulley will always turn counter-clockwise to remove cable slack. - See illustration on Page 4-9A)
Spool up the excess cable slack by turning the ratchet pulley counter-clockwise by hand. Continue to hold
the ratchet pulley while proceeding to the next step.
While maintaining the position of the ratchet pulley with your left hand, press down on the engagement
pawl and the linkage bar with your index and middle fingers of your right hand in order to begin the final
tensioning process. You will feel and hear the pawl click several times as tension is taken up.
Inspect your progress by pulling the upper hook of the blue spring into the top notch of the tension bar;
then raise the tension bar. Refer to the illustrations on the following page for proper setting. Repeat steps 1-
5 until the bottom of the linkage bar is essentially horizontal, and is aligned within the gray "pie" zone of the
indicator label (see Figure B). Lower tension bar until system is ready to test.
To test the Detection Network, refer to Chapter 5, "Testing and Commissioning".

INSTALLING THE DETECTION NETWORK - MRM
To install the detector linkage, place a weighted object on the cable at the MRM, allowing a minimum of 3
inches of extra cable length for every detector in the network. Starting at the terminal detector, place the
linkage upside-down on the cable, run the cable over the rivet and through each of the four tabs as shown
above, insert the appropriate fusible link (see the design section for proper selection of fusible links) and turn
upright. Repeat these steps for each detector.
Each link and link holder, once assembled and placed on the
cable, should be positioned in the bracket on center or slightly
off center away from the MRM.
To set the tension on the cable, first make sure that the
tension bar in the MRM is in the "down" position and that
the spring is relaxed.
WARNING: DO NOT ATTEMPT TO SET THE TENSION

SECURE CONDUIT PROPERLY MAY
CAUSE SYSTEM FAILURE.
Attach the cable to the link plate connector, do not clamp tightly
(slack must be taken up in a later step). Insert the connector
into the slot on the link plate that corresponds with the direction
of pull on the cable. The link plate is marked with clock
positions (6:00 and 12:00).
Note: Early models also had a 3:00 and 9:00 position
which CANNOT be used.
Insert the connector at 12:00 if the cable enters the MRM
at the TOP or 6:00 if it enters at the BOTTOM.
NOTE: Any excess cable must be secured out of the
way of any parts in the MRM. We suggest taping it to
the link line cable.
Slip the set-up/lock-out tool (PIN 12738) over the manual
pull cam housing until it rests against the outside edge of
the collapsible linkage. (See adjacent illustration) Draw
tension on to the cable through the connector until the link
plate is drawn against the set-up tool, then tighten the set
screw on the connector.
Remove the set-up tool and raise the tension bar to test
cable run. Lower tension bar until system is ready to test.

INSTALLING THE LINEAR FUSIBLE LINK DETECTION NETWORK - MRM, MRM II
Refer to the system design section for Linear Fusible Link Detection Network limitations. This network uses no
detector brackets and is limited to use in hoods 42' long or less. The terminal connector is located at the end of
the cable run. The fusible links and factory fabricated cable segments are supported every eight feet maximum
by the use of support eyebolts PN17520. Eyebolts must also be located on each side of the hood-duct opening to
support the cable crossing the opening.
Starting at any of two sides (top or bottom) of the MRM or MRM II at the corresponding knock-out, install 1/2' EMT
conduit running from the MRM, MRM II to the hood, a maximum distance of thirty feet. This run of conduit may
also incorporate the use of a maximum of twenty corner pulleys at every change in direction and conduit must be
firmly secured every 36 inches. This portion of the network uses Cable Segment PN17356 (Part of Purchased
Kit 17515) which consists of one link hook and thirty feet of stainless steel cable. No field fabrication of any
Cable Segments is allowed.
The first fusible link must be located within 24 inches of the end of the hood. Each fusible link from this point on
must be on maximum 24" centers, which is accomplished by the use of Cable Segment PN17354 which consist of
two link hooks and stainless steel cable the proper length for the maximum 24" spacing. No field fabrication of
any Cable Segments is allowed.
The last fusible link in the line must be within 24" of the end of the hood and is terminated by the use of cable
segment PN17355 (Part of Purchased Kit 17515) which consist of one link hook and 24" of stainless steel cable.
No field fabrication of any Cable Segments is allowed. The end of the cable segment is terminated at a conduit
handy box by the use of the terminal clamp PN12859 (provided with the MRM & MRM II). Refer to the Design
section for limitations and cautions regarding fusible link placements. The network is to be run in the plenum in a
manner that will place a fusible link in the "hood-duct" opening. All cable and links in the plenum are to be in a
straight line and supported by eye bolts a maximum of every eight feet. Support eye bolts are to be located in the
middle of cable segment runs to allow for the required cable movement.
NOTE: WHEN POSITIONING THE LINKS IN THE PLENUM SO THAT A LINK IS IN THE HOOD-DUCT
OPENING IT MAY BE NECESSARY TO LOCATE THE END LINKS AT LESS THAN THE MAXIMUM 24" FROM
THE END OF THE HOOD.
To install the linear fusible link network, first measure the distance from the far end of the hood to the middle of
the hood/duct opening in inches. Divide this distance by 24 and you will know the number of "Links to Link"
Segments (PN17354) required to run from the end of the hood to the middle of the hood/duct opening. You will
also require one "Link to Termination" Segment PN17355 (Part of Purchased Kit 17515).
Next measure from the center of the "hood/duct opening to the opposite end of the hood and repeat the process
above to determine the balance of "Link to Link" Segments (PN17354) required. You will also require one "MRM
to 1st Link" Segment PN17356 (Part of Purchased Kit 17515).
Tension adjustment for the linear fusible link network is to be performed in the same manner described for the
standard detection network on page 4-9 and 4-10 of this manual.

INSTALLING THE MANUAL PULL STATION(S) -
MRM, MRM II OR PRM
To install the manual pull station(s) first confirm that the
set-up/lock-out tool is in place, that the tension bar is
down and that an actuation nitrogen cylinder is not
installed. Failure to confirm these conditions could
result in the discharge of the system.
Refer to the design section for manual pull station
limitations and suggested locations. The local AHJ
should have the final approval for manual pull station
location and mounting heights.
The MRM, MRM II or PRM allows the cable for the
manual pull station(s) to enter from any of the two sides
(TOP or BOTTOM). Once a location for the pull station
has been established, 1/2 EMT conduit is run from the
module (using whichever exit side is most convenient)
through corner pulleys to the pull station. The manual
pull station may be mounted to the wall in any orientation
necessary for surface mounting. The conduit and pulley
elbows must be mounted and securely anchored and
then the cable can be fed from the manual pull station
back to the MRM, MRM II or PRM.

INSTALLING THE ACTUATION NETWORK
Refer to the Design section for limitations of the Actuation Network. Piping for the actuation network can be 1/4'
black, chrome plated, galvanized schedule 40 pipe, copper tubing or hose. The network originates at the pipe
outlet of the MRM, MRM II or PRM and continues to the top of each cylinder and valve assembly. The protective
plug on each cylinder valve and the MRM, MRM II or PRM must be removed. All pipe used for the actuation
network must be reamed and blown clear, mounted to a sufficient structure, adjusted for level and plumb and
fastened in an appropriate manner. Pipe must be fitted tight (three turns past hand tight recommended). All
threaded connections in the actuation network must be sealed with Teflon tape (applied to male threads
only). Starting with the third thread from the pipe opening, wrap the Teflon tape clockwise around the
threads moving away from the pipe opening. Make certain that tape does not extend past the end of the
pipe - it could dislodge and possibly block the actuation network.
CAUTION: Do not over tighten the pipe or pipe fittings into the pipe threads on the MRM. Over
tightening can cause the MRM to malfunction.
A single MRM, MRM II or PRM will actuate a maximum of ten (10) agent cylinders. The ten cylinder may
be any combination of 275, or 375, or 475 Agent Cylinders. When a 600 is included in the mix of agent
cylinders the total maximum allowable agent cylinders is lowered to six (6). Outlined below are the
maximum amounts of pipe, hose or tubing allowed in the actuation network. When a network consists of
more than one of the media listed, the total allowable footage is equal to the smallest of the two media
limits.
EXAMPLE: An actuation system made up of black pipe and hose would limit the total footage of pipe
plus hose to 22.2 feet.

FLEXIBLE NOZZLE BRANCH HOSE (PN20473)
This hose is designed to be used when a f.exible movement of the nozzle branch line is desired. Such as when an
appliance needs to be moved for cleaning and the nozzle protecting the appliance is fixed to the appliance. Hose
length is 48" end to end and is supplied with /2" NPT ends. THE FLEX HOSE IS LIMITED TO USE ON THE
NOZZLE BRANCH LINE ONLY AND CANNOT BE USED ON SUPPLY LINE OR SUPPLY BRANCH LINE.
When installing the flexible hose the use of an elbow on the stationary piping at the appliance is helpful in
reducing stress on the hose when the appliance is in its cooking position. The nozzle branch drop should be
located in a manner that will provide the maximum movement of the appliance without causing the flexible hose to
kink or collapse. In some installation this may be directly over the fixed piping and in other installations it may be
out board of the fixed nozzle.
Never locate the flexible hose where it is exposed directly to hot exhaust gases. Example: Over the top of an
open top char-broiler. The flex hose is never to be installed behind an obstruction or wall.
Only one flex hose is to be used on an individual nozzle branch line. A maximum of three hoses may be used on
an agent cylinder piping network. The minimum bend radius of the flex hose is 7" (17.8 cm).
The castered appliance must be furnished with an appliance locating device. This will assure the appliance is
returned to the required position after being moved for cleaning.
When attaching the flexible hose to a 3/8" pipe drop, a 1/2 coupling with a reducing busing may be used to
transition from the pipe to the hose.
When a system discharge occurs the hose is to be cleaned and drained of any agent remaining in loops

Amerex Restaurant Fire Suppression System (EX 4658)
TESTING & COMMISSIONING
Testing and commissioning shall be performed by a trained and certified Amerex restaurant distributor in
accordance with NFPA 96, NFPA 17A and local code requirements.
Once the Amerex Restaurant Fire Suppression System has been completely installed, two sets of tests must
be conducted prior to placing the system in service. The detection network, using any fusible link style or the
pneumatic tubing, must be tested for functionality along with the manual pull station(s), gas valve(s) and other
interlocks. Once this is accomplished and confirmed the action network must be tested using a nitrogen
actuation cartridge. Recharging of the nitrogen cartridge can be accomplished by following the instructions on
Page 7-6 and 7-7.
TESTING THE DETECTION NETWORK - MRM or MRM II
The terminal detector must have a test link (P/N 12891) installed in place of the fusible link. With the
nitrogen actuation cartridge removed from the release module; the release mechanism cocked; the tension
bar in the "up" (tension) position and the set-up/lock-out tool removed; cut the test link with a pair of dikes or
similar device. The MRM must actuate at this time.
If the MRM did actuate, follow the reset instructions, place the proper fusible link on the terminal detector
and continue with the system test.
If the MRM did not actuate, check to see if:
the detectors are installed properly,
that the cable is not binding at any point in the conduit or corner pulley(s),
that the cable is connected to the link plate properly,
that the tension bar is in the "up" position and that the set-up/lock-out tool is not in place
that the conduit is rigidly fastened in place
that the proper tension exists on the link line
Once these items have been investigated and resolved, RETEST.
TESTING THE DETECTION NETWORK - PRM
When first placing the system into service, following system actuation, or at the six month servicing interval,
the detection network shall be tested prior to conducting an actuation network test:
Insure removal of the Nitrogen Actuation Cylinder.
Slowly release the detection pressure until the panel actuates by performing either of the
following:
a Depress the Schrader valve on the detection accumulator cylinder. Replace Schrader
cap following actuation and re-pressurization.
b Slowly loosen the knurled nut on the end and check for leaks of line fitting. Re-tighten
the nut following actuation and thoroughly leak check the entire PRM assembly and
tubing following re-pressurization.
If the PRM did actuate, follow reset instructions and continue with the system test.
If the PRM did not actuate, check to see if:
that the PRM was properly cocked
that the "End of Line Fitting" did properly vent the pressure from the accumulator
that the accumulator pressure reading dropped to zero
that the set-up/lock-out tool is not in place
that the slide plate and puncture pin are free to function
that the trip plunger is free to move without resistance
Once these items have been investigated and resolved, RETEST.
April 2011 Section 5 Testing and Commissioning Page 5 - 2
Amerex Restaurant Fire Suppression System (EX 4658)
TESTING THE MANUAL PULL STATION - MRM, MRM II OR PRM
After the detection network has been tested and before inserting the nitrogen actuation cylinder the
manual pull station(s) must be tested. We recommend having an employee of the restaurant :emove the pull
pin on each manual pull station, grab the handle and pull away from the mounting surface. Confirm that each
manual station did not require a pull force in excess of 40 lbs. and that the handle did not require pulling a
distance of more than 14 inches. The MRM, MRM II or PRM must actuate at this time.
If the MRM or PRM did actuate, for each station, replace the pull pin, attach a tamper seal and follow the
reset instructions.
If the MRM or PRM did not actuate:
the pull station is installed properly,
the cable is not binding anywhere in the conduit, corner pulley(s) or pulley tee,
the cable is connected properly to the manual pull cam in the MRM or PRM,
the set-up/lock-out tool is not in place.
The MRM is properly set and cocked.
Once these items have been investigated and resolved, RETEST.
TESTING THE MECHANICAL GAS VALVE - MRM. MRM II OR PRM
With the gas on and appliances working pull on the cable leading to the gas valve where it connects to the
piston plug/gas trip assembly in the MRM or PRM. A 1/2 inch cable movement will be sufficient to close the
gas valve. The gas valve(s) must release at this time.
If the gas valve(s) do release, follow the reset instructions and continue with the test.
If the gas valve(s) do not release, check to see if:
it has been installed properly,
it is fitted tightly into the gas line,
the cable is not binding in the conduit or in a corner pulley(s),
it has been connected to the release module properly and that the cable has been secured properly
to the gas valve trip mechanism. Insure that the red vinyl cap is properly installed.
Once these items have been investigated and resolved, reset.
TESTING THE ACTUATION NETWORK AND MECHANICAL GAS VALVE WITH A NITROGEN
ACTUATION CYLINDER
After performing the mechanical gas valve test above, then you MUST test the actuation nework and gas
valve together using a NITROGEN ACTUATION CYLINDER. Before inserting the NITROGEN ACTUATION
CYLINDER insure that all fittings on the actuation line are tight and secure. This test can be done in
conjunction with the "puff or air test" or alone.
If testing with a "Puff' test:
Confirm that all components of the system are properly installed and the test cylinders are connected and
charged with compressed air or nitrogen - no fire suppression agent. Either the pull station is pulled or a test
link is cut to actuate the system. All system functions should occur at this time. Confirm that the gas valve
closed, the actuation line was tight and secure, the agent cylinders valves opened and the pipe and nozzles
are clear.
If there is no need to perform a "Puff' test:
You can simply connect a valve assembly removed from a cylinder or pneumatic actuator disconnected from
the cylinder to the actuation line. Pull the pull station or cut a test link to actuate the system and confirm total
system functioning. Insure that the discharge valve is being opened, the actuation line has no leaks, and gas
valve(s) closed properly.
April 2011 Section 5 Testing and Commissioning Page 5 - 3
Amerex Restaurant Fire Suppression System (EX 4658)
TESTING THE DISTRIBUTION PIPING NETWORK
The Amerex Restaurant Fire Suppression System is a wet chemical suppression system using pre-
engineered piping limitations that do not require balancing. As long as the design limitations for the
distribution piping network as stated in the design section have NOT been exceeded, there should be no
concern regarding proper distribution of agent at each discharge nozzle. Bag Tests" or discharge tests are
not considered necessary.
"PUFF" TEST
To confirm that the distribution network piping is clear and intact, a Puff Test" or "Air Test" may be performed.
This test may be performed as an individual test or as part of a functional test.
When performing a "Puff Test" as part of a functional test, all other components of the system are installed,
including the nitrogen actuation cylinder and an agent cylinder assembly charged with compressed air or
nitrogen only to 100 psi (689.48 kPa) - no fire suppression agent.
Either a manual pull station is activated or a test link is cut and all system functions, including auxiliary outputs
and discharge of air or nitrogen through the distribution piping, should occur at this time. All functions are
confirmed and documented and the system is recharged and reset.
To perform the "Puff Test" as an individual test:
Replace agent cylinder(s) with test cylinder(s) and actuate the system.
Confirm that each nozzle is clear and continue testing.
TESTING THE ELECTRICAL GAS VALVE - MRM, MRM II or PRM
With the gas valve and the appliances working follow the procedure for testing the manual pull station. When
the manual pull station(s) is activated and the MRM/PRM actuates, the snap action switch(es) must transfer
contacts cutting off current to the electric gas valve. The Manual Reset Relay shall show an "off' condition. If
this does not happen, turn the power to the relay and electric gas valve off and check all electrical
connections RETEST.
TESTING COMPLETED
After all testing has been completed, follow reset instructions and put the system on line, including the
nitrogen actuation cylinder and all tamper seals. The testing procedures and results should be documented in
written form with copies left for the owner/manager, Local AHJ (if required) and a copy put into the
permanent job file. Amerex P/N 13023 "Commissioning Checklist" or similar form shall be used.

codes and NFPA 96 and NFPA 17A). Notify the owner or owner's agent of any problems or
code violations - in writing with a copy to be placed in the permanent job file.
Check the entire distribution network piping, nozzles and caps to verify that they have not been
altered or damaged. Perform "puff test" or "air test" in accordance with 'Testing and Commissioning"
instructions using a NITROGEN ACTUATION CARTRIDGE.
CAUTION: SOME HOOD AND DUCT CLEANING PROCEDURES MAY DAMAGE THE
DETECTION NETWORK OR LEAVE DETECTORS IN A CONDITION WHERE
THEY MAY NOT OPERATE. AMEREX RECOMMENDS THAT THE SYSTEM BE
SERVICED AFTER EACH CLEANING BY AN AUTHORIZED AMEREX
RESTAURANT SYSTEMS DISTRIBUTOR.
Amerex requires that all fusible links be replaced in intervals not to exceed 6 months. Links
that do not need replacing must be thoroughly cleaned before being put back into service. Any
fusible link found to be damaged, painted or having excessive grease must be replaced regardless of
age. The links that are removed shall be destroyed. Any link exposed to excessive heat or flame
shall be removed from service and destroyed.
A system using the PRM requires that the tubing be replaced at intervals not to exceed (3) years.
Record the installation date and the date of replacement on the tubing replacement label on the
Detection Accumulator Cylinder. The entire length of tubing must be replaced, either at the three
year interval or following a fire incident. If grease or coating build-up is excessive, a more frequent S replacement interval will be required. At a minimum, excessive build-up is defined as when material . completely encircles the tube at any point along its length. Cleaning the tube is acceptable, provided
that no abrasives are used, and that the text on the outside of the tubing is still legible when 5 completed. Use only a soft cloth with mild detergents and warm water. If the tubing appears
brittle or charred REPLACE it. "When in Doubt, Take it OUT". Corrective action should be
taken to re-evaluate the environment where the tubing is installed, or a more frequent tubing
inspection and/or replacement interval must be used. The End of Line Fitting Assembly (P/N
16506) must be replaced when the tubing is replaced. Do not attempt to re-use the Fitting or the
Sealing Ball. Thoroughly leak check the tubing terminations following re-installation and re-
pressurization.

7. The Pneumatic Release Module (PRM) 0-ring (P/N 17692) on the brass actuation piston must be
replaced every six months.
Materials required: 1 1/8" open-end wrench, 5/32" Allen wrench, clean, lint-free shop towels,
0-ring (P/N 17692), and Visilox lubricant (available as p/n 06247 in a 5 oz. tube).
Remove the cover of the PRM and make sure the nitrogen actuation cylinder is removed.
Remove the screw anchoring the spring to the brass block with a 5/32" Allen wrench. The
silver lever should now swing down away from the brass block.
Unscrew the cap off of the Schrader valve and bleed the pressure off of the accumulator
cylinder. Confirm that the pressure gauge reads zero.
With the 1 1/8" open-end wrench, loosen and remove the brass hex nut that retains the piston
spring and piton inside the brass block. A shop towel may be required to grip the end of the
brass piston for extraction from the block. Take care to use only your hands to remove the
piston. VERY IMPORTANT: DO NOT use pliers or tools to remove the piston from the
bore or the 0-ring from the piston groove. Scratches will cause system leaks and
unwanted system discharges.
With a clean shop towel, wipe out all the old grease from the inside the cylindrical bore at the
deepest point inside the brass block. Using the Visilox V-711 lubricant, thoroughly and
completely wipe the internal bore in a circular motion with a clean finger. Make sure that
you reach all the way to the rear of the bore with the lubricant.
Clean off the old grease from the piston 0-ring. Using a dry shop towel, 'pinch' the 0-ring until
it can be slipped over the end of the piston by hand. DO NOT use a sharp instrument to
remove or cut the old 0-ring off of the piston - scratches on the brass will create a leak point.
Clean the groove of the piston prior to installing the new 0-ring. Liberally lubricate the 0-ring
on the piston with Visilox before inserting into the brass block.
VERY IMPORTANT - Lubricate both the 0-ring and the internal bore! Use NO TOOLS to
remove the old 0-ring.
After inserting the new piston all the way into the bore, slide the spring over the end and re-
tighten the brass hex retaining nut until resistance is felt. Do not over-tighten, as spring
tension will present the nut from backing out.
Temporarily pressurize accumulator through the Schrader valve with approximately 40-50
psi. Re-attach the screw which retains the lever spring to the corner of the brass block.
Tighten securely. Latch the tip of the actuation lever under the exposed tip of the piston.
Apply the lube totally around the perimeter of the exposed brass piston tip of the trip
mechanism. Work the piston in and out several times to distribute the lube. Additionally,
place some lube on the tip of the spring-loaded lever where it contacts the underside of the
piston tip.
Re-pressurize to 70 psi and leak check all fittings. Perform a full function test of the PRM at
this time, as well as the remainder of the six month maintenance.
8. Use the digital thermometer to record the temperatures found at each detector location (with
appliances running) and compare with those temperatures found at the same location during the last
system maintenance. Insufficient air movement, excessive grease build up and appliance changes
can cause temperatures to elevate even to the point of system discharge without a fire occurring.
INCREASING THE TEMPERATURE SETTING OF THE FUSIBLE LINK IS NOT AN ACCEPTABLE
SOLUTION TO THIS PROBLEM.
9. The agent cylinder assembly and nitrogen actuation cylinder must be checked for proper pressure
(within the green pie OPERABLE RANGE on pressure gauges).
10. The agent cylinder and all hose assemblies must be hydrostatically tested at a minimum of every 12
years.
a Agent Cylinder - test to 480 psi (3309 kPa)
b Actuation Hose (if used) - test to 3500 psi (24131 kPa)
c Distribution Hose - Test to 480 psi (3309 kPa)
If the agent cylinder or hose assemblies have been subjected to physical damage, excessive heat or
corrosion they should be hydrostatically tested or replaced regardless of their age.

11. Replace nitrogen actuation cylinder, REMOVE SET UP/LOCK OUT TOOL, replace the MRM cover
and install new tamper seals.
12.After performing a complete functional test of the system the owner or owner's agent shall receive
some documentation on the maintenance performed (with a copy to be placed in the permanent job
file) and instruction on how the system and related hand portable fire extinguishers work, including
procedures for incidents.

Slowly pressurize the N2 cylinder to 1800 psi at 70°F.
NOTE: The nitrogen may experience a significant temperature rise as it compresses into the cylinder. The
temperature rise must be compensated for by pressurizing to the valve corresponding to 1800 psi at the higher
temperature. The best method to properly pressurize is to attach a commercially available magnetic base
thermometer to the side of the N2 cylinder. Pressurize and hold the cylinder at 1800 psi. (Make sure that there
are no leaks in the nitrogen supply plumbing.) Let the apparatus sit undisturbed for 2 minutes minimum to allow
the temperature to stabilize. Read the temperature on the thermometer. Refer to Temperature/Pressure chart
on Page 7-8. Locate the temperature on the "Cylinder Temperature" (horizontal) axis of the graph. Draw a line
vertically upward from that temperature until it crosses the "Nominal Pressure" line. Draw a second line
horizontally from the point of intersection to the "Charge Pressure" (vertical) axis of the graph. Increase the
pressure from the regulated nitrogen supply to match the valve read from the "Charge Pressure" axis of graph.
Use only DRY nitrogen for pressurizing with a dew point of —70°F (-57°C) or lower.
When the proper pressure is reached:
Tighten the rupture disc by applying a torque wrench to the recharge adapter and tighten
(clockwise) to 40 foot pounds.
Shut off nitrogen supply.
Bleed and disconnect the supply hose.
Remove nitrogen cylinder from the recharge adapter.
Check for leaks using leak detect fluid (soapy water) to the rupture disc, the threads on the
rupture disc fitting where it joins the cylinder and the pressure gauge threads. Bubbles may take
several minutes to appear. Blow dry fluid from all surfaces and inside of the rupture disc
following leak detect. Install shipping cap.

Appendix A Special Application Guidelines
The information contained in this Section is exclusively for use in the
protection of risks for which a Loss Prevention Certification Board System
Approval Label is required.
Appendix Al:
The installation of a Deep Fat Fryer Nozzle PN13 729 at a height lower than its
listed minimum is only permitted if provisions are made to accommodate the resultant
splashing of grease. This need may occur due to the low height of the hood provided
over the appliance. In the event of such a situation precautions must be taken to prevent
the splashing of the hot grease onto persons or flammable material located adjacent to the
appliance. Any opening that would allow this to happen must be closed off by the
installation of a guard of sufficient size to prevent the splashing. The required guard
height above the appliance is limited to the size of the opening or 18" whichever is less.
A guard higher than 18" is permitted but not required. This provision will then allow the
nozzles to be located at a height less than the listed minimum. The lowest nozzle height
is limited to 16" above the liquid level of the grease.
Extinguishment at this lower height is enhanced due to the increase of agent being
applied directly to the burning grease and none being allowed to spray outside the
appliance. A high degree of fire safety is achieved and public safety is preserved.
Appendix A2:
The term "Commercial" is used interchangeably with "Industrial" as it applies to
cooking appliances. Both refer to the preparation of food for sale, with the primary
difference being the quantity of food cooked and to whom the consumer is. None of
those considerations are of any importance when it comes to fire suppression and safety.

Inhalation: If respiratory irritation or distress occurs remove victim to fresh air. Seek
medical attention if irritation develops or persists.
Ingestion: If victim is conscious and alert, give 2-3 glasses of water to drink and on the
advice of medical personnel induce vomiting. Seek immediate medical attention. Do
not leave victim unattended. To prevent aspiration of swallowed product, lay victim on
side with head lower than waist. If vomiting occurs and the victim is conscious, give
water to further dilute the chemical.
Medical conditions possibly aggravated by exposure: Skin contact may aggravate
existing skin disease. Chronic overexposure may affect blood cholinesterase levels
and the central nervous system.
Section 5. Fire fighting measures
Extinguishing media: non combustible and non flammable - product is an
extinguishing agent
Unusual fire/explosion hazards: in a fire this material may decompose, releasing
oxides of phosphorus, carbon, and acetic acid (see Section 10).
Insensitive to mechanical impact or static discharge.
HMIS hazard ranking: health 1, flammability 0, reactivity 0, personal protective
equipment: eye protection, gloves and appropriate skin protection (see Section 8)
Section 6. Accidental release measures
Large spills (one drum or more) should be addressed by hazardous materials
technicians following a site-specific emergency response plan and trained in the
appropriate use of PPE. Clean up released material using sorbent socks for
containment, followed by sorbent material inside containment. If deemed necessary,
wear full face APR or PAPR with organic vapor cartridges (Section 8). Bag and drum
for disposal. If product is used and/or contaminated, for example if mixed with kitchen
grease, use PPE and containment appropriate to the nature of the mixture. Handle

Section 7. Handling and storage
Avoid skin, eye, or respiratory exposure. Use appropriate PPE when handling or
maintaining equipment, and wash thoroughly after handling (see Section 8). Keep
product in original container or extinguisher. Contents may be under pressure -
inspect for extinguisher rust periodically to insure container integrity. Do not mix with
other extinguishing agents.
Section 8. Exposure controls/ personal protection
During the application of this product against fires, exhaust gases and the products of
incomplete combustion (PlCs) are the principal respiratory hazards. In the
manufacture of extinguishers, automated systems and point source ventilation controls
sufficiently minimize respiratory exposure. Employers and employees must use their
collective judgment in determining occupational settings where the use of a respirator
is prudent. The need for respiratory protection is not likely for short-term use in well
ventilated areas.
Respiratory protection: use air-purifying respirator (APR) or powered air-purifying
respirator (PAPR) with organic vapor cartridges/canisters for short term exposure, and
supplied air!SCBA for high concentration or prolonged exposure.
Eye protection: wear chemical goggles.
Skin protection: use nitrile, latex, or similar gloves and coveralls. Good personal
hygiene practices essential, such as avoiding food, tobacco'products, or other hand-to-
mouth contact when handling. Wash thoroughly after handling.

Approval
The Pnuematic Release Module (PRM) is UL IULC Listed as a Heat Actuated Device for Special
Applications (S7253) and is intended for use with the Amerex IS (Industrial Dry Chemical) and KP
(Restaurant Wet Agent) Fire Suppression Systems, only.
The use of the PRM should be reviewed and authorized by the local authority having jurisdiction
(AHJ) before installation.
I) General:
This single hazard module supervises and controls one Fire Suppression System. Proven,
rugged mechanical components are reliably set into motion with a simple pneumatic detectijn
interface. The PRM is listed with Amerex IS Industrial and KP Restaurant Pre-Engineered
Fire Suppression Systems. The PRM meets the detection requirements of NFPA codes 96,
17, and 17A.
-2- UL EX 4658 / EX5208
Jure, 2014
P/N 16546 Page -3-
II) Installation:
Detection
The PRM has provisions for a single, continuous section of detection tubing. No splicing or
"tee's" allowed. There shall be only two tubing terminations: one at the accumulator
assembly inside the PRM, and the other at the opposite end of the tubing, with the use of an
End of Line Fitting (p/n 16506). Install the tubing in areas where the maximum sustained
ambient temperature does not exceed 176 F (80o Q. Exposing the tubing to random and
infrequent temperature spikes up to (but not exceeding) 375o F (190.5o C) is acceptable.
A properly designed commercial kitchen hood meeting the requirements of NFPA 96 should
maintain temperatures above the filter bank well below 176 F (80 Q. However, areas above
certain high-heat appliances such as (but not limited to) upright broilers, solid fuel appliances, or
charbroilers can reach and maintain temperatures above 176 F (80 C). Other factors, such as a
low hood height over the appliances, can lead to elevated ambient temperatures. The use of
baffles to redirect exhaust flue gasses from direct impingement on the tubing might be necessary,
but may not always be effective. Installation of the tubing into areas beyond the temperature
maximum may shorten the useful life of the tubing and require a more frequent replacement
interval. Therefore, a thorough operating temperature survey MUST BE conducted in all
applications prior to installation of a PRM to determine its suitability.
The Amerex part numbers for tubing lengths are:
P/N Length
16557 25'
16551 50'
16579 100'
16552 150'
16554 300'
Tubing may be cut down to the required length, or be coiled up and secured with wire ties
outside the hazard area. Cuts must be square and clean. The minimum bend radius is 6
inches, as illustrated below:
-3- UL EX 4658 / EX5208
June, 2014
P/N 16546 Page -4-
Do not crimp or crush the tubing in the course of handling or installation. A Tubing Clip
(p/n 16501) is required at least every 18" of tubing. A Tubing Clip is also required within
one inch of the End of Line Fitting. The tubing can exit the panel either through the 5/8" hole
at the upper right hand corner of the enclosure (where strain relief fitting is installed at
factory), or it can exit through the 5/8" hole at the top right of the enclosure. If it is desired tc
route it through the top, switch the strain relief fitting with the snap-in plug.

connections. The following are instructions for termination:
Tubing Termination at the PRM:
Remove knurled nut from plated tube fitting and slide over end of tubing. The end of
the tubing must be cut square and clean. DO NOT use pliers or wire cutters for cutting
the tube. These tools will collapse the end of the tubing and could create a leak point.
The use of the Amerex p/n 16860 Tubing Cutter is required. Do not use any sealants
on the connection.
Firmly push the end of the tube down over the end of the fitting. If necessary, the use
of a heat gun (placed on its lowest setting) may be used to warm the end of the tubing
prior to pushing it on the fitting. Do not exceed 176° F (80o C) at the tubing, and only
warm approximately one inch of the tubing end. It is important that the end of the
tubing be inserted ALL the way over the tip of the fitting and firmly bottoms at the
base of the fitting. (See the following figure). Hold the tubing in place firmly in one
hand while tightening the nut with the other. Use a 12mm wrench (or adjustable) to
tighten the nut. Resistance will be felt when the nut bottoms out. Do not over tighten.

Tubing Termination at the End of Line (EOL):
Remove knurled nut from End of Line fitting and slide over the end of the tubing. The end of
the tubing must be cut square and clean. DO NOT use pliers or wire cutters for cutting the
tube. These tools will collapse the end of the tubing and could create a leak point. The use of the
Amerex p/n 16860 Tubing Cutter is required. Do not use any sealants on the connection.
Flare the end of the tubing slightly with the tip of the fitting. Insert the p/n 17135 black Sealing
Ball into the flared end of the tubing. Firmly push the end of the tube down over the end of the
fitting, pushing the ball into the tubing. If necessary, a heat gun (placed on its lowest setting) may
be used to warm the end of the tubing prior to pushing it onto the fitting. Do not exceed 176° F
(80 C) at the tubing, and only warm approximately one inch of the tubing end. It is important that
the end of the tubing be inserted ALL the way over the tip of the fitting. It may be helpful to place
the End of Line Fitting in a small vise while pressing the tubing into position. Hold the tubing in
place firmly with one hand while tightening the nut with the other. Use a 12mm wrench (or
adjustable) to tighten the nut (See the following figure). Resistance will be felt when the nut
bottoms out. Do not over tighten.

Once the system is pressurized and put into service, both connections should be thoroughly
leak checked with a commercial leak check fluid, such as that used in the natural gas industry.
Record the date of tubing installation on the tubing replacement label on the accumulator
cylinder, and affix the label to the detection accumulator cylinder as shown at the end of this
section.
Warning: it is imperative that the field terminations be properly made. YOU, the
installer, are responsible for system functionality following installation and placing into
service. Failure to properly handle and terminate the tubing can result in air leakage,
which will result in an unwanted system discharge. Allow at least 20 minutes for the leak
check fluid to indicate any presence of leakage. Even the smallest visible stream of
bubbles can cause the system to lose pressure and discharge in just a few days.
Securing the Tubing: The tubing must be secured at a distance not to exceed 18" with p/n
16501 Tubing Clips. A Tubing Clip is also required within one inch of the End of Line Fitting.
Since the tubing snaps into the clip, it is recommended that the clips be installed first, then the
tubing. Ensure that the tubing is routed in such a way as not to interfere with any moving parts
or access openings. Tubing must not be obscured by structural or support structures, and
should be fully exposed to any rising hot gasses, to ensure rapid detection response. Never take
up slack by pulling the tubing through a series of clips, this action could damage the tubing
and shorten its useful life.
Tubing Spacing Requirements:
IS Applications:
In large applications, in order to provide adequate fire detection, it may be
necessary to form a "U" or "S" along the ceiling of the hazard. The maximum
spacing between parallel runs of tubing must not exceed ten (10) feet. The tubing
must be within four (4) feet and no less than two (2) feet from the adjacent wall.
Maximum Height Limitations:
Type of IS Coverage Maximum Installed Ceiling Height*
Total Flood 16 feet
Vehicle Paint Spray Booth 16 feet

Low Pressure Switch (UL file: E225513)
While the pressure gauge of the accumulator cylinder displays the detection system pressure, this gauge may
not always be readily visible. The purpose of the low pressure switch is to provide a remote means to alert
personnel that the pressure in the pneumatic detection system has dropped to a level approaching system
activation (discharge). Any indication of pressure loss in the PRM requires that the system be serviced,
without delay, to avoid an unwanted system discharge. Personnel at the installed system location should be
trained to recognize the need to contact a trained and certified Amerex distributor in this event.
The PRM is supplied with a SPST pressure switch with contacts that are held open under pressure. The lo
pressure switch is factory installed and sealed in the top of the 22633 accumulator assembly. The low
pressure switch is provided with two wires on each side of the contacts to allow for proper connection to a
supervisory circuit on a fire alarm panel. Electrical terminations must be made in UL-listed junction boxes
outside the PRM. The switch has gold-plated contacts rated as shown below:
50/60 Hz, 36 VDC, 1A
120/240 VAC 6.0 FLA, 36 LRA
24 VAC 125 VA pilot duty
120/240 VAC 375 VA pilot duty
The contacts will close at 60 psig (corresponding to the low side of the "green pie" range on the pressure
gauge). If a noticeable drop in pressure occurs, the pressure switch closing point will allow a short
period of time for personnel to act, before the system discharges. The contacts will re-open at 70 psi,
during re-pressurization. When re-pressurizing the PRM, ensure that the contacts re-open, and that any
connected device is returned to normal.

Fire Suppression - Agent Release
Upon either a manual or automatic response to a fire, an internal Nitrogen Cylinder (either the
10 in p/n 12856, or the 15 in p/n 09956) will expel dry nitrogen which is pressurized to
1,800 psig (12,411 kPa) at 70°F (21°C). The nitrogen gas is used to open the Agent Cylinder
Valves, which in turn, releases the agent. For Actuation Network limitations, see below:

System(KP) 15 in p/n 12385 KP or 16640 ZD Installation Manual - MRM Limitations
Mechanical and Electrical Gas Valve
The PRM is capable of closing up to two (2) mechanical gas valves upon system actuation.
Electrical gas valves are operated through the use of the micro switches. Refer to the
appropriate Amerex KP, ZD, or IS Installation Manual for design limitations, installation, and
servicing instructions of the gas valve(s).
Mechanical Time Delay
If a 10-20 second discharge delay is required (as in the case of Vehicle Paint Spray Booths,
for example), the p/n 15765 Mechanical Time Delay is installed at the actuation pressure outlet
of the PRM. Refer to the Amerex IS Installation Manual (p/n 15040) for design limitations,
installation, and servicing instructions of the Mechanical Time Delay.
PRM Mounting Instructions (Must be Surface-Mounted, Only)
Instructions for mounting (see figure on following page). All installation wiring shall adhere
to NFPA 70 (NEC) and all State and Local codes. Terminations of the Microswitches are to
be made outside the PRM Enclosure in an appropriate electrical junction box.
Remove necessary knockouts on metal enclosure.
Insert mounting hardware (not provided) into wall, spaced to match keyholes on back of box.
Mount box on to the screws.
Tighten all screws.

III) Maintenance / Rechar2e:
Inspection and Servicing the Detection Tubing: The tubing must be replaced at intervals
not to exceed three (3) years. Record the installation date and the date of replacement on the
tubing replacement label on the Detection Accumulator Cylinder (see figure above). The
label is shipped in the bag assembly with the Control Panel. The entire length of tubing
must be replaced, either at the three year interval or following a fire incident. If grease or
coating build-up is excessive, a more frecuent replacement interval will be required. At a
minimum, excessive build-up is defined as when material completely encircles the tube at
any point along its length. Cleaning of the tube is acceptable, provided that no abrasives are
used, and that the text on the outside of the tubing is stl1 legible when completed. Use only
a soft cloth with mild detergents and warm water. If the tubing appears brittle or
charred., REPLACE it. "When In DOUBT, Take It OUT." Brittle or charred tubing is
evidence of excessive temperatures on the tubing. Corrective action should betaken to
re-evaluate the environment where the tubing is installed., or a more frequent tubing
inspection and/or replacement interval must be used. The End of Line Fitting assembly
(p/n 16506) must be replaced when the tubing is replaced. Do not attempt to re-use either
the Fitting or the Sealing Ball. Thoroughly leak check tubing terminations following re-
installation and re-pressurization.

Resetting Steps, Following Panel Activation / System Release: (if a manual actuation
has occurred, first reset the Manual Pull Station)
Pressurize the Accumulator Cylinder to approximately 35 PSI with compressed air through
the Schrader Valve. The Trip Plunger should extend.
Rotate the Spring Loaded Lever clockwise ('1" in Figure A), until its tip is latched under the
Trip Plunger. Resume pressurization of the Accumulator Cylinder to 80 PSI at 700F.. Leak
check the fittings at both ends of the tuing. Re-make tubing terminations, if necessary.
Using the Amerex Cocking Tcol, p/n 13341 in conjunction with a 3/8" drive socket wrench
and extension, re-cock the Collapsible Column ("2" in Figure A). This is accomplished by
simultaneously pushing in on the Lock Spring while turning the Cocking Tool
counterclockwise. The mechanism should now appear as depicted in Figure B.
Follow Maintenance and Recharge Insfructicns in the applicable Amerex Installation,
Operation, and Maintenance Manual w.th regard to the Manual Pull Station(s), Actuation
