GENERAL INFORMATION
The Amerex KP Series Restaurant Fire Suppression System is designed and has been tested to provide fire
protection for commercial cooking operations coveting the hood, ducts, plenum and appliances. Amerex KP
Systems are a pre-engineered type as defined in NFPA hA - 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 Series Systems be performed in compliance with this
manual. Those individuals responsible for the design, installation, operation and maintenance of the
Amerex KP Restaurant Fire Suppression System must be trained by Amerex and hold a current
Amerex KP 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 Series System listings.
LISTINGS:
The Amerex KP Series is a listed pre-engineered restaurant fire suppression system. The KP system is 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 System consists of mechanical and electrical components to be
installed by an Authorized Factory Trained and Certified Amerex KP Systems distributor. The system is
composed of an agent cylinder/discharge valve charged with Amerex KP Liquid Agent and a Mechanical
Release Module (MRM) 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 KP System suppresses fire in commercial cooking equipment by spraying KP liquid agent in a
predetermined 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 must be automatically shut off
along with all cooking appliances. Some local Authorities Having Jurisdiction may require exhaust fans to be
shut down by the fire suppression system. Check local fire codes and requirements in the specific area that
the system is being installed.
The Amerex KP System agent storage cylinders and cartridge shall not be installed in environments below
32° F or above 120° F (0° C to 49° C).
CYLINDER MOUNTING BRACKET (P/N 16085)

Assembly is shipped factory filled with Amerex KP Liquid Agent. It
is pressurized with dry Nitrogen to a pressure of 240 psi (1655 kPa)
at 70°F (200C). The nitrogen charge is the expellant gas which
discharges the KP agent through the distribution network. Cylinders
are shipped from the factory with a shipping plate installed on the top
of the valve to prevent accidental discharge and an anti-recoil -plate
on the valve outlet to redirect chemical flow should an accidental
discharge occur. BOTH OF THESE PLATES MUST BE REMOVED
AT INSTALLATION.
Agent cylinders are DOT 4BW240, tested to 480 psi (3309 kPa) and
require a hydrostatic test every twelve (12) years. The
operating temperature of this and other listed components is 32°F to
120°F (0°C to 49°C ). The cylinder is fitted with an attachment
bracket welded to the cylinder for ease of installation. The machined,
forged brass discharge valve is actuated via a pneumatic actuator.

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 %" 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 spiral retainer ring that locks the piston in its extended
position.

INSTALLING THE DISTRIBUTION PIPING NETWORK:
General
For distribution piping network limitations please refer to the design section.
ONLY SCHEDULE 40, BLACK, CHROME PLATED OR STAINLESS STEEL PIPE CAN BE
USED FOR THE DISTRIBUTION NETWORK. GALVANIZED PIPE IS NOT ALLOWED.
ALL PIPE MUST BE REAMED AND BLOWN CLEAR. DIRT AND/OR CUTTING OIL MUST
BE REMOVED FROM THE INSIDE OF ALL PIPE AND FITTINGS BEFORE ASSEMBLY.
All piping must be securely bracketed to a rigid surface using appropriate hangers and/or clamps.
All distribution network pipe and fittings are to be assembled tight (3 turns past hand tight recommended). UNLESS SPECIFICALLY REQUIRED BY THE LOCAL AUTHORITY HAVING JURISDICTION, THE USE
OF TEFLON TAPE IS PROHIBITED. JOINT SEALANT OR PIPE COMPOUND MAY NOT BE USED
UNDER ANY CIRCUMSTANCES.
The Amerex KP Restaurant Fire Suppression System does not require balanced piping. All distribution
network piping shall be run in as direct a manner as possible throughout the hazard. The distribution network
piping, once installed, shall be compared with the design drawing or sketch, any changes or deviations
shall be noted for use in preparing an "as-built" drawing or sketch for the permanent job file.
Piping installation shall start at the cylinder bracket and continue through the hazard with tees installed at the
beginning of each branch line location. Branch lines shall then be installed taking care to assure that each
nozzle is located properly and that no design limitations have been exceeded. NOZZLE LOCATION AND
ORIENTATION ARE CRITICAL TO ACHIEVING PROPER SYSTEM PERFORMANCE.
TO INSTALL HIGH TEMPERATURE BLOW OFF CAPS:
Standard Nozzle: Remove standard blow off cap - thread the loop of the high temp. cap onto the base of the male threads on the nozzle. Install 0-ring on nozzle tip, place cap on nozzle tip. Swivel Adapter: Remove standard blow off cap - thread the loop of the high temp. cap onto the supply pipe before installing the nozzle body. Install 0-ring on nozzle tip, place the cap on
nozzle tip.
DETECTION NETWORK LIMITATIONS: MRM
Optimum fire suppression system performance relies on proper detection network design. This section
discusses the type of detectors used, their selection, placement and design limitations.
The Amerex KID Restaurant Fire Suppression System MRM 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 DETECTOR LOCATION AND NUMBER OF DETECTORS
In order to detect a fire in the duct, a detector is required to be placed in the center of the duct, either at the
duct opening or up to 12 inches into the duct. If it is mounted into the duct, the bracket cannot 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
p EXHAUST FLUE GASES. DOING SO COULD
J RESULT IN UNNECESSARY DISCHARGE OF
THE SYSTEM.
GENERAL LIMITATIONS OF DETECTION

ELECTRIC GAS VALVES
I (77 Electric gas 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 microswitch in the MRM 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 electric gas
valves. UL listed sizes are %", 1", 1W, 1/2", 2", 2W, 3".

MECHANICAL RELEASE MODULE (MRM) (P/N 11977)
The mechanical release module is used to actuate the agent
cylinder/discharge valve either automatically or manually by
puncturing a nitrogen cylinder. The pressure from the
cylinder pneumatically opens the discharge valve(s).
Automatic release of agent is accomplished when a fusible
link detector separates under a fire condition and releases
tension on the cable. This causes a spring-loaded plunger to
perforate the cylinder seal and releases nitrogen through the.
actuation hose/piping network to the discharge valve(s).
Manual release of agent is accomplished by pulling on a
manual pull station which is connected to the mechanical
release module by a cable.
The mechanical release module is equipped with one
microswitch (P/N 12524) for electrical signaling, power
shutdown and other auxiliary functions. An additional three
microswitches may be added.
Operation of one or two mechanical gas valves may be
accomplished by adding a piston plug/gas trip assembly (P/N
12740).
The cable for the gas valves, manual pull stations and
detection network may be attached to the MRM from
any of three sides (top, bottom and right).
