MANUAL
R-102 RESTAURANT
FIRE SUPPRESSION
SYSTEM
(Standard UL 300 Listed)
C
This manual is intended for use with Ansul R-102 Restaurant
Fire Suppression Systems.
Those who install, operate, recharge, or maintain these fire sup-
pression systems should read this entire manual. Specific sec-
tions will be of particular interest depending upon one's
responsibilities.
Fire suppression systems are mechanical devices. They need
periodic care. Maintenance is a vital step in the performance
of your fire suppression system. As such it must be performed
in accordance with NFPA 96 (Standard for the Installation of
Equipment for the Removal of Smoke and Grease-Laden Vapors
from Commercial Cooking Equipment) and NFPA 17A (Standard
on Wet Chemical Extinguishing Systems) by an authorized Ansul
distributor. To provide maximum assurance that the fire sup-
pression system will operate effectively and safely, maintenance
must be conducted at six-month intervals, or earlier if the situa-
tion dictates. Twelve-year maintenance must include agent tank
hydrostatic testing.

SECTION I - GENERAL INFORMATION
UL EX. 3470 11-1-94 Page 1-1
DESIGN AND APPLICATION
The Ansul R-102 Restaurant Fire Suppression System is
designed to provide fire protection for restaurant cooking appli-
ances, hoods, and ducts. It is a pre-engineered group of mechan-
ical and electrical components for installation by an authorized
Ansul distributor. The basic system consists of an ANSUL
AUTOMAN regulated release assembly which includes a regu-
lated release mechanism and a liquid agent storage tank housed
within a single enclosure. Nozzles, detectors, cartridges, liquid
agent, fusible links, pulley tees, and pulley elbows are supplied
in separate packages in the quantities needed for each fire sup-
pression system arrangement.
The system provides automatic actuation; or it can be actuated
manually through a remote manual pull station. The gas or elec-
trical supply to all protected appliances will be immediately shut
off upon actuation of the system, using appropriate gas shut-
off or electrical shut-down devices.
Additional equipment includes: remote manual pull station,
mechanical and electrical gas valves, pressure switches, and
electrical switches for automatic equipment and gas line shut-
off. Accessories can be added, such as alarms, warning lights,
etc., to installations where required.
The R-1 02 system suppresses fire by spraying the plenum area,
the filters, cooking surfaces, and the exhaust duct system with
a predetermined flow rate of ANSULEX Low pH Liquid Fire Sup-
pressant. When the liquid agent is discharged onto a cooking
appliance fire, it cools the grease surface, and reacts with the
hot grease (saponification) forming a layer of soap-like foam on
the surface of the fat. This layer acts as insulation between the
hot grease and the atmosphere, thus helping to prevent the
escape of combustible vapors.
Exhaust fans in the ventilating system should be left on. The
forced draft of these fans assists the movement of the liquid
agent through the ventilating system, thus aiding in the fire sup-
pression process. These fans also provide a cooling effect in
the plenum and duct after the fire suppression system has been
discharged. The system is UL listed with or without fan operation.
It is also recommended that make up or supply air fans be shut
down upon system actuation. Shutdown of fuel and power to
all appliances located under protected ventilating equipment is
required upon system actuation.
UL LISTING
The R-102 Restaurant Fire Suppression System has been tested
and is listed by Underwriters Laboratories, Inc. as a pre-
engineered system. These tests require extinguishment of fires
which are initiated in deep fat fryers, griddles, char-broilers,
upright broilers, chain-broilers, filters, plenum chambers, hoods,
and ducts after pre-loading each appliance with a prescribed
amount of cooking grease. Each fire is allowed to progress to
maximum intensity before the fire suppression system is
actuated.
DEFINITION OF TERMS

EXTINGUISHING AGENT
ANSULEX Low pH Liquid. Fire Suppressant (1.5 gallon - Part
No. 79694 or 3.0 gallon - Part No. 79372) is a potassium-based
solution designed' for fast knock-down and suppression of
grease-related fires. The agent is shipped in plastic containers
which provide one complete tank charge. Agent storage life
expectancy is twelve years. The distributor must record the batch
numbers and date of shipment receipt to be filed with each instal-
lation record.

REGULATED RELEASE ASSEMBLY (MECHANICAL)
The ANSUL AUTOMAN Regulated Mechanical Release
Assembly (3.0 gallon - Part No. 79290 or 1.5 gallon - Part
No. 79291) contains the regulated release mechanism, agent
tank, expellant gas hose for agent tank hookup, and enclosure
knockouts to facilitate installing actuation piping; expellant
piping; detection system; and additional equipment. This regu-
lated release assembly is used in single, double, and multiple-
tank systems and nust be mounted to a rigid surface. The
release mechanism can be used to interconnect both the actu-
ation and expellant gas lines as required per system design. The
regulator is designed to allow a constant flow of gas into the
tank at 100 psi (690 kPa) when the system is actuated.
In single, double, and multiple-tank systems, the provided expel-
lant gas hose connects the agent tank to the bottom outlet of
the regulator. In double and multiple-tank system configurations,
the back outlet of the regulator is used as an expellant gas feed
for one additional tank-enclosure or tank-bracket hookup. The
enclosure contains the required knockouts to facilitate this con-
nection. If a pressure switch is to be attached to the regulator,
additional fittings are required.
The tank is mounted within the enclosure. The tank contains
an adaptor/tube assembly with a burst disc union. The burst disc
helps prevent siphoning of the agent up the pipe due to signifi-
cant temperature fluctuations in the area where the tank is
located. The tank is mild steel and, under normal conditions,
requires hydrostatic testing every twelve years.
The agent tank is shipped uncharged and must be filled with
1.53 gallons (5.8 L) or 3.06 gallons (11.6 L) of only ANSULEX
Low pH Liquid Fire Suppressant during installation.
The detection and additional equipment required per system
design are connected :0 the release mechanism. The enclosure
contains knockouts to facilitate detection and additional hookups.
The system can be actuated automatically or manually. Auto-
matic actuation occurs when a fusible link within the detection
system separates in a fire condition. Manual actuation of the
system occurs when personnel pull on the remote manual pull
station pull ring.

DETECTORS
The detector consists of three basic components: the bracket,
linkage, and fusible link. (Fusible links are not included and must
be ordered separately.) The baôket holds the entire assembly
to the mounting surface. The linkage is used to support the
fusible link. The fusible link is designed to separate at a specific
temperature and release the wire rope, thereby actuating the
regulated release mechanism.
There are three styles of detectors available: the clip-on style,
the hinged style, and the scissor style.
The clip-on style allows the wire rope to be strung completely
through the detection system conduit and brackets first and the
detector linkage assemblieS are then clipped on later.
The hinged style detector requires the wire rope to be strung
to the detector bracket, and then threaded" through the linkage
assembly before continuing to the next detector bracket.
The scissor style allows the wire rope to be strung completely
through the detection system conduit and brackets first and the
detector linkage assemblies are then clipped on later.
Each style of detector consists of two types of assemblies:
The Terminal Detector (Part No. 56838, 15375, or 417368)
includes a test link and is placed last in a series of detectors.
This detector is sometimes referred to as the end-of-line detector
and is thus named because it is at the point at which the wire
rope "terminates," or is anchored at the detector bracket. Only
one terminal detector is required per detection system.
The Series Detector (Part No. 56837, 15373, or 417369) is
any detector located in-line between the regulated release
assembly and the terminal detector.
When using Part No. 56837 and 56838 style detectors, a total
of 12 detectors can be in one detection system: 11 series
detectors, Part No. 56837 and 1 terminal detector, Part No.
56838.
When using Part No. 15373 and 15375 style detectors, a total
of 5 detectors can be in one detection system: 4 series detectors,
Part No. 15373 and 1 terminal detector, Part No. 15375.
When using Part No. 417368 and 417369 style detectors, a total
of 15 detectors can be in one detection system: 14 series
detectors, Part No. 417369 and 1 terminal detector, Part No.

NOTICE
In installations where a UL listed damper
assembly is employed, the duct nozzle can be
installed beyond the 8 in. (20 cm) maximum,
to a point just beyond the damper assembly
that will not interfere with the damper.
Exceeding the maximum of 8 in. (20 cm) in
this way will not void the UL listing of the
system.
To correctly locate the nozzles in the duct, the longest side
of the duct must be divided into four equar modules. See
Figure 10.

9. Multiple-Nozzle Duct Protection:
For ducts larger than 150 in. (254 cm) perimeter, the total
perimeter of the duct must be divided by 75. If the answer
contains a decimal (or fraction), it must be rounded-up to
the nearest whole number. This answer signifies the number
of equally-sized modules in which the duct must be divided.
The diagonal dimension of each module must not exceed
35.5 in. (90.2 cm). If diagonal dimension is exceeded, addi-
tional module divisions must be added until the diagonal
dimension is not exceeded. A nozzle must then be centered
in each module.
Example: Figure 20 shows a duct opening of 270 in. (686
cm) perimeter. By dividing 270 in. (686 cm) by
75, it is determined that the duct must be
divided into 4 equally-sized modules. Because
the diagonal dimension of each module is 33.54
in. (85.2 cm), it is within the maximum limit of
35.5 in. (90.2 cm) and therefore acceptable as
shown in Figure 21. One nozzle is then centered
in each module as shown in Figure 22.

Electrostatic Precipitator Protection
Some restaurant ventilating ducts have an electrostatic precipi-
tator installed at or near the base. These precipitators are used
to aid in the cleaning of exhaust air.
Normally electrostatic precipitators do not require protection but
should the "authority having jurisdiction" require protection, use
the following guidelines.
Ducts with precipitators located at or near the base can be pro-
tected using duct nozzle(s) above the precipitator and 1/2N
nozzle(s) (Part No. 56929) for the precipitator. One 1/2N nozzle
must be used for each cell being protected. This nozzle tip is
stamped with 1/2N, indicating that it is a 1/2-flow nozzle and must
be counted as 1/2 flow number.
When protecting ducts equipped with precipitators, the duct
nozzle(s) must be installed above the precipitator and aimed to
discharge downstream. If the area above the precipitator is a
duct, the nozzle(s) must be positioned according to duct pro-
tection guidelines. If the area above the precipitator is a transi-
tion, the transition guidelines must be followed. See Figure 20.

The 1/2N nozzle (Part No. 56929) must be centered 10 to 26

at the center of each precipitator cell. However, if it is physi-
cally impossible to mount the nozzle at 10 to 26 in. (25 to 66
cm) due to precipitator placement, the nozzle may be mounted
closer than 10 in. (25 cm). See Figure 23.

The R-1 02 system uses the 1W Nozzle (Part No. 56927) or the
iN Nozzle (Part No. 56930) for plenum protection; The 1W
nozzle tip is stamped with 1W and the 1 N nozzle tip is stamped
with 1 N, indicating they are both one-flow nozzles and must be
counted as one flow number each.
1W NOZZLE - PART NO. 56927
One 1W nozzle will protect 4 linear feet (1.2 m) of plenum. The
maximum distance from the end of the hood to the first and last
nozzle must be no more than 2 ft. (.6 m). After the first nozzle,
any additional nozzles must be positioned at a maximum of 4
ft. (1.2 m) apart down the entire length of the plenum. The
plenum width must not exceed 4 ft. (1.2 m). (The 1W nozzle can
be used on single or V-bank filter arrangements.) See Figure 24.
FIGURE 24
When protecting plenums with the 1W nozzle, two options of
coverage are available:
Option 1: The 1W nozzle must be on the center line of the
single or "V" bank filter and positioned within 1-20
in. (2.5-51 cm) above the top edge of the filter. See

For a plenum, either single or "V' bank, with a linear extension
longer than 8 feet (2.4 m), each bank may be protected using
one 1 N nozzle every 8 ft. (2.4 m) or less depending on the overall
length of the plenum. See Figure 28. The nozzles may point in
the opposite directions as long as the entire plenum area is pro-
tected, and the 8 ft. (2.4 m) limitation is not exceeded. See Figure

o. The following pages detail types of appliance protection. Each
design requires several factors: correct nozzle choice, correct
nozzle height above azard, correct nozzle location and correct
aiming point.
When protecting appliances which are larger than single nozzle
coverage, multiple nozzles can be used.
Larger appliances can be divided into several modules, each
equal to or smaller than single nozzle coverage. Exception:
, Fryers must not exceed a maximum of 864 sq. in. (5574 sq. cm).
Single Nozzle Fryer Protection — 2-Flow High Proximity!
2-Flow Medium Proximity
If the fryer does not have a drip board, the maximum hazard
(fry pot) size is 15 in. (38 cm) x 14 in. (36 cm) (maximum area
of 210 sq. in. (1355 sq. cm)). If the fryer has a drip board, the
maximum hazard (cooking surface) size is 21 in. (53 cm) x 14
in. (36 cm) (maximum area of 294 sq. in. (1897 sq. cm)). The
maximum fryer pot size must still not exceed 15 in. (38 cm) x
14 in. (36 cm) (210 sq. in. (1355 sq. cm) of maximum area.) The
nozzle must be aimed at the center of the hazard area.
The R-1 02 system uses two different style nozzles for the pro-
tection of fryers.
1. High Proximity Applications: 27 to 47 in. (68 to 119 cm)
above the top surface of fryer. See Figure 31a and Figure

The 230 Nozzle (Part No. 418117) is used for high prox-
imity applications. The nozzle tip is stamped with 230,
indicating that this is a two-flow nozzle and must be counted
as two flow numbers.
When using this nozzle for fryer protection, the nozzle tip
must be positioned anywhere along or within the perimeter
of the maximum hazard area and angled to the center.

The R-102 system uses two 1 Nozzles (Part No. 56930) for
chain broiler protection. The nozzle tip is stamped 1 N, indicating
that this is a one-flow nozzle and must be counted as one flow
number (total of two flow numbers for each chain broiler being
protected).
Two 1 N nozzles are always needed for chain broiler protection
when the hazard area to be protected does not meet the "Over-
head Broiler Protection" requirements. The maximum internal
size of the broiler is 43 x 31 in. (109 cm x 79 cm). The nozzles
must be positioned at each end of the enclosed cooking chamber
1 to 3 in. (2.5 to 7.5 cm) above the surface of the chain and a
maximum distance of 4 in. (10 cm) away from the broiler opening.

Overhead Chain Broiler Protection
The R-102 system uses two 1W Nozzles (Part No. 56927) for
overhead chain broiler protection. The nozzle tip is stamped with
1W, indicating that this is a one-flow nozzle and must be counted
as one flow number.
Overhead protection is only available for chain broilers with
exhaust opening dimensions that are not less than 60% of the
internal broiler length and not less than 60% of the internal
broiler width, to a minimum size of 12 in. x 12 in. (30.5 x 30.5
cm). Internal broiler size can not be larger than 32 in. x 34 in.
(81 x 86 cm).
Example No. 1 - Internal broiler size is 24 in. long x 20 in.
wide (61 x 51 cm), with an opening of 16 in. x 16
in. (40.6 x 40.6 cm).
To determine minimum opening size, multiply the
internal length and the internal width by 0.6:
Length of opening - 24 in. x 0.6 = 14.4 in. (61 cm
x 0.6 = 36.6 cm)
Width of opening - 20 in. x 0.6 = 12.0 in. (51 cm
x 0.6 = 30.5 cm)
The minimum allowable opening for overhead pro-
tection would be 14.4 in. x 12.0 in. (36.6 x 30.5 cm).
This example would be acceptable for overhead
protection.
Example No. 2 - Internal broiler size is 30 in. long x 24 in.
wide (76 x 61 cm) with an opening of 22 in. x 12 in.
(56 x 30 cm).
To determine minimum opening size, multiply
internal length and internal width by 0.6:
Length of opening - 30 in. x0.6 = 18.0 in. (76cm
x 0.6 = 45.7 cm)
Width of opening - 24 in. x 0.6 = 14.4 in. (61 cm
x 0.6 = 36.6 cm)
Minimum allowable opening for overhead protection
would be 18 in. x 14.4 in. (45.7 x 36.6 cm).
Because this broiler has an opening of 22 in. x 12
in., the 12 in. width is below the minimum allowable
calculated dimension of 14.4 in. (36.6 cm) and there-
fore would not be acceptable for overhead
protection.
When overhead protection is used, the nozzles must be cen-
tered above the exhaust opening within 4 to 8 in. (10'to 20 cm)
of each other and they must be located 10 to 26 in. (25 to 66
cm) above the top of the broiler surface. See Figure 48.

The nozzles may vary in position as long as they are evenly

be positioned along the centerline, parallel to the longest side
of the opening. See Figure 49.

broilers in a special way. The guidelines for protecting these
broilers are as follows:
- The maximum internal broiling area is 29 in. x 23.5 in. (74
cm x 60 cm).
- An R-102 3-gallon system with a maximum of 6 flow
numbers, must be used for protection of each broiler,
including plenum and duct.
- Each individual broiler must be protected with a minimum
of (2) two, iN nozzles, Part No.56930. The nozzles must
be located as shown in Figure 50.
- The broiler must be fitted with two 1 in. (2.5 cm) high agent
barriers on the angled surface of the broiler. See Figure 50.

TANK AND CARTRIDGE REQUIREMENTS
Once the hazard analysis is completed and the total nozzle flow
numbers are established, the quantity and size of agent tanks
and cartridges needed to supply the nozzles with the proper
volumes of agent at the proper flow rates can be determined
For cartridges used in the regulated release mechanism, flow
capacities, tank quantities and sizes, and regulated release car-
tridge options are given in the table below.

**The 101.30 cartridge Part No. 15851, can not be used when (2) two 3.0 gallon tanks are
rnanifolded together.)
For higher total flow numbers (23 to 110), multiple cartridges
and regulated actuators are required as shown in the System
. Selection Guide in Section IX - Appendix.
ACTUATION AND EXPELLANT GAS LINE REQUIREMENTS
This section contains the guidelines for installing the actuation
and expellant gas lines between the regulated release mecha-
nism regulator, each regulated actuator regulator, and each
agent tank. These limitations should be considered when
selecting the component mounting locations.

(Part No. 15851). See Figure 60.
DISTRIBUTION PIPING REQUIREMENTS
Once the nozzle placement and quantity of tanks has been deter-
mined, it is then necessary to determine the piping configura-
tions between the tank adaptor and each discharge nozzle. This
section contains the guidelines and limitations for designing the
distribution piping so that the liquid agent will discharge from
the nozzles at a proper flow rate. These limitations should also
be referred to when selecting the mounting location for the regu-
lated release mechanism and agent tank.
General Piping Requirements
1. All R-102 system piping is straight line. Therefore, the need
for critical lengths and balancing is minimized.
2 Two 450 elbows count as one 900 elbow.
3. Each branch line includes the tee or elbow leading to it, and
all fittings within the branch line itself.
The minimum piping length of Schedule 40, 3/8 in. pipe from
the tank outlet to any nozzle protecting a range, fryer, or
wok must be 6 ft. (1.8 m).
Pipe lengths are measured from center of fitting to center
of fitting. See Figure 64.
CENTER TO CENTER
FIGURE 64
6. All distribution piping must be Schedule 40 black iron,

galvanized pipe on the distribution piping.

Detector Placement Requirements
EXHAUST DUCTS
Each exhaust duct must have at least one detector installed in
the duct entrance, located in the airstream of the cooking vapors,
or at a maximum of 20 ft. (6.1 m) into the duct opening. See
Figure 75.
20 FT. (6 m)
MAXIMUM
FIGURE 75
NOTICE
When gas appliances are used and the flue
gases from the burner are exhausted into the
duct, the detector must be kept out of the air
stream of these exhaust gases. These gases
can be very hot and could actuate the system
unnecessarily.
Duct openings that are long and narrow or
large enough to require multiple duct nozzles
may require additional detectors.
ELECTROSTATIC PRECIPITATOR
If an electrostatic precipitator is located at or near the base of
the exhaust duct, it is necessary to locate a detector below the
precipitator, at the base of the duct, and also locate one in the
duct, just above the precipitator. See Figure 76.
When installing the detector bracket and system conduit, make
certain they do not interfere with the operation of the precipitator.
FIGURE 76
SECTION IV - SYSTEM DESIGN
UL EX. 3470 11-1-94 Page 4-35
PUt) DETECTION SYSTEM REQUIREMENTS
Once the fire suppression system design has been determined,
a detection system design must be completed. This section con-
tains guidelines and limitatibns for detection system installation.
Detector Identification
The two types of detectors are distinguished from each other
by their location in the detection system.
The Terminal Detector (Part No. 56838, 15375, or 417368)
is the last in a series of detectors, or the only detector used
in a single-detector system. This detector is thus named
because it is at the point at which the wire rope ends, or
"terminates."
A Series Detector (Part No. 56837,15373, or 417369) is any
detector located in-line between the regulated release mech-
anism and the terminal detector.
Detector/Pulley Elbow Quantity
The quantity of detectors used in the system will vary depending
on the style of detector used.
Conduit runs, pulley elbows, and number of detectors per
system must be within the approved system guidelines. The
following requirements must not be exceeded:
Maximum Maximum Maximum
Number of Number of Length of 1/2
Detectors Elbows in. Conduit
per System per System per System
'ow
Clip on Style 12 18 125 ft.(38.1 m)
Detector
Hinge Style 5 8 103 ft. (31.3 m)
Detector
Scissors Style 15 20 150 ft. (45.7 m)
Detector
If styles of detectors are mixed within a system, 4 series
and 1 terminal is the maximum number allowed.
NOTICE
When using the "clip-on" style detector, the
terminal detector may use the "hinged" style
mounting bracket with the "clip-on" style
linkage. This is only allowed with the terminal
detector. When using this option, the total
number of "clip-on" style detectors (11 series
and 1 terminal) is still allowed.
If detector styles are mixed in the detection system, the max-
imum length of wire rope must not exceed 103 ft. (31 ;4 m)
and the maximum number of pulley elbows must not exceed
8.
If the hazard requires more than 15 detectors, up to five
101 Remote Releases (Part No. 12029) can be used for
system actuation. Each 101 remote release allows the use
of a maximum of 15 "scissor" style detectors (14 series and
1 terminal) for a total of 75 detectors if needed.

ELECTRICAL GAS VALVE REQUIREMENTS (Continued)
Once the R-102 system is activated, the normally closed con-
tacts in the snap-action switch will.open, de-energizing the reset
relay. This will, in turn, open the contacts in the relay which will
cause the gas valve to become de-energized and close.
The system must be re-armed and the "push to reset" button
on the reset relay must be operated to reopen the gas valve.
It is important to note that a power failure or an electrical power
interruption will cause the gas valve to close even though the
system was not fired.
In either case, whether in a fired condition or when a power
failure has occurred, the manual reset relay and electric gas shut-
off valve must be reset to resume a normal operating condition.
For resetting, refer to the "Recharge and Resetting Proce-
dures" section in this manual.
Approvals
Ansul gas valves listed in this section are UL listed and approved
for 110 VAC. If more information is required, refer to the Gas
and Oil Equipment List of Underwriters Laboratories, Inc. under
"Electrically Operated Valves Guide No. 440 A5" or consult
Ansul Incorporated, Marinette, Wisconsin 54143-2542.
If other gas valves are used, they shall be "UL listed electrically-
operated safety valves for natural or LP gas as required, of
appropriate pressure and temperature rating, 110 VAC/60 Hz."
The information on temperature and type of gas that the valves
re suitable for may be found in the Gas and Oil Equipment List
)f Underwriters Laboratories, Inc. under "Electrically Operated
Jalves Guide No. 440 A5."
The electrically operated gas valve must be of the type that
needs to be energized to remain open.

INSTALLATION INSTRUCTIONS
Before attempting any installation, the entire system design must
have been determined including: Nozzle Placement, Tank Quan-
tity, Actuation and Expellant'Gas Piping, Distribution Piping, and
Detection System Requirements and an installation sketch
should be completed.
MOUNTING THE COMPONENTS
For successful system performance, the regulated release
assembly, regulated actuator assembiy(ies), and tank-
enclosure(s) or tank-bracket assembly(ies) used must be located
in areas where the air temperature will not fall below 32 OF
(0 °C) or exceed 130 OF (54 oc). Also, the components must
be arranged to conform to the actuation and expellant gas line,
and the distribution piping guidelines noted in "System Design."
Use only an ANSUL AUTOMAN Regulated Release
assembly (Part No. 79290 - 3.0 gallon mechanical or
79292 - 3.0 gallon electrical or 79291 - 1.5 gallon
mechanical or 79493 - OEM Release/Bracket
Assembly). The regulator in this assembly is specifically
designed to allow a regulated flow of expellant gas into
the agent tank(s). Absence of this regulator could cause
the tank(s) to rupture or create an improper system
discharge.
Mount the regulated release assembly, OEM Release
Assembly, and each regulated actuator assembly required
by completing the following steps: See Figures 1, 2, and 3.
Select a rigid surface for mounting the enclosure. The
mounting locations must allow the regulated release
assembly and the regulated actuator assembly(ies) to
be within the limitation of the actuation and expellant
gas line lengths and must be able to support the weight
of the assembly(ies).
Detach cover from the enclosure. Remove agent tank
from enclosure and the expellant gas line hose from
the tank/adaptor assembly.
Secure enclosure box to selected mounting location
using the four mounting holes. Use appropriate type
of fasteners depending on the mounting surface.
When mounting a 6-gallon manifolded system (or a 6-
gallon individual piped system) it is critical that each
mounting box is located as shown in Figure 3a. There
must be a 5/16 in. space between each box. Less than
5/16 in. will cause interference with the covers, and
more than a 5/16 in. will cause a gap between the two
hose grommets which will expose the hose to possible
'tampering or damage.
Remove the 7/8 in. knockout in the left side of the
ANSUL AUTOMAN release box and remove the 1 in.
knockout in the right side of the tank-enclosure box.
Install grommets in each (use Ansul hose/grommet
package, Part No. 418511). Remove 1/4 in. plug from
back side of R-102 regular and install fixed end of
secondary expellant gas hose (included in
hose/grommet package, Part No. 418511) in 114 in.
regulator outlet and wrench tighten.
If not already done, mount both boxes to a rigid sur-
face using appropriate fasteners.
Fill tanks per instructions listed in Steps 3 and 4 on
Page 5-3.
Next, route hose through grommets and wrench tighten
into 1/4 in. inlet of the adaptor on the tank in the
tank/enclosure assembly. Also install hose to tank
adaptor in regulated release and wrench tighten. See
Figure 74b for details of hose routing.

immediately.
Place plastic funnel in fill opening and fill tank with 1.5
gallons (5.8 L) or 3 gallons (11.6 L) of only ANSULEX
Low pH Liquid Fire Suppressant. When the tank con-
tains a complete charge, the liquid level should be 1
in. ± 1/8 (2.54 cm ± . cm) from the bottom of the
fill opening. See Figure 6.
Make certain tank is filled to 1 in. ± 1/8 in. (2.54
cm ± .3 cm). During filling, the agent temperature
should be 60 °F to 80 °F(16 °C to 27 OC) DO NOT
FILL WITH COLD AGENT. DO NOT OVERFILL.
Overfilling may result in agent entering gas hoses
and regulator potentially causing system
malfunction.

INSTALLING THE ACTUATION AND EXPELLANT GAS LINE
Before installing any actuation or expellant gas line, the piping
design must be determined; and the regulated release assembly,
each regulated actuator 'assembly and each tank-bracket
assembly should be securely mounted.
General Piping Requirements
Use only 1/4 in. Schedule 40 black iron, hot-dipped galva-
nized, chrome-plated, or stainless steel pipe and fittings.
Before assembling the pipe and fittings, make certain all
ends are carefully reamed and blown clear of chips and
scale. Inside of pipe and fittings must be free of oil and dirt.
The piping and fitting connections must be sealed with pipe
tape. When applying pipe tape, start at the second male
thread and wrap the tape (two turns maximum) clockwise
around the threads, away from the pipe opening.
NOTICE
Do not allow tape to overlap the pipe opening,
as this could cause possible blockage of the
gas pressure.
Thread sealant or compound must not be
used.
When connecting actuation or expellant gas line piping,
install a 1/4 in. union near the tank inlet for easy disassembly
later.-
Actuation Gas Line
Install actuation gas line from the regulated release mechanism
high pressure side outlet (side opposite regulated outlet) through
the appropriate knockout in the enclosure by completing the fol-
lowing steps:
1. Remove the 1/8 in. plug from high pressure side outlet.
Install the appropriate fitting for additional equipment attach-
mentas required. A 1/4x 1/8 in. reducing fitting is required
to connect the 1/4 in. actuation line. See Figure 7.

Install expellant gas line from the regulated release assembly
regulator in the enclosure by completing the following steps-
1 . The regulated release assembly is shipped with a factory-
installed regulator. The regulator has two 1/4 in. outlets, one
at the back and one at the bottom. The bottom outlet con-
nects the expellant gas hose to the agent tank which is
mounted inside the enclosure. The back outlet is sealed with
a 1/4 in. plug.
Connect expellant gas hose to the agent tank mounted
inside the enclosure. If a pressure switch is required, a 1/4
in. x 1/8 in. reducing fitting will be required for connection
between the back regulator outlet and the pressure switch.
See Figure 7.
DOUBLE AND MULTIPLE TANK SYSTEMS:
If the expellant gas piping is required because an additional
tank-enclosure or tank-bracket assembly is being installed,
the plug installed in the back outlet must be removed. (See
Figure 6 for proper connections to the regulator.)
Pipe the 1/4 in. expellant gas line from the regulator back
outlet through one of the knockouts provided in the
enclosure.
The total length of the expellant gas line from the regulated
release assembly must not exceed 30 ft. (9 m) when using
a "double-tank" nitrogen cartridge (Shipping Part No.

INSTALLING THE DISTRIBUTION PIPING
Before the following procedures can be completed, the piping
design must already be determined; and the actuation and expel-
lant gas lines from the regulated release, each regulated actu-
ator, and each tank-enclosure or tank-bracket assembly should
already be installed.
These installation instructions are identical for single, double,
and multiple-tank systems except for the quantity of tanks and
hazard areas to be covered.
General Piping Requirements
Use Schedule 40 black iron, chrome-plated, or stainless
steel pipe and fittings.
NOTICE
Do not use hot-dipped galvanized iron pipe or
fittings in the agent distribution piping.
Before assembling the pipe and fittings, make certain all
ends are carefully reamed and blown clear of chips and
scale. Inside of pipe and fittings must be free of oil and dirt.
The distribution piping and fitting connections, located in
the protected area, must be sealed with pipe tape. When
applying pipe tape, start at the second male thread and wrap
the tape (two turns maximum) clockwise around the threads,
away from the pipe opening.
NOTICE
Do not allow tape to overlap the pipe opening
as the pipe and nozzles could become
plugged.
Thread sealant or compound must not be
used as it could plug the nozzles.
Distribution piping may be run independently or two agent
tanks may be manifolded together and run to the predeter-
mined hazard area. Only agent tanks expelled from the
same cartridge may be manifolded.
NOTICE
Closely f011ow the piping requirements for
each size system, as detailed in the "System
Design" section, when installing distribution
piping.
Piping Installation
1. Starting at the tank, pipe directly from the union located on
the tank adaptor. A reducing fitting may be necessary to
conform to the distribution piping.
2. Based on the piping sketch developed in the "System
Design" section of this manual, install the supply line and
position the tees at points where branch lines must be
installed. See Figure 13.
FIGURE 13
3. Run all branch lines to the hazard area and connect each
nozzle. (Make certain all fittings are tight and all piping is
securely bracketed.) The 1WS and iNS nozzles can be
aimed by slipping a 3/8 in. Schedule 40 pipe over the tip,
moving the tip to the correct aiming point, and then wrench
tightening the retaining ring.
4 All threaded connections located in the protected area, must
be sealed with pipe tape. Tape should be applied to male
threads only. Make certain tape does not extend over the
end of the thread, as this could cause possible blockage
of the agent distribution.
Before installing blow-off caps on nozzles, apply a small
amount of Dow Corning No. lii silicone grease across the
opening in the nozzle tip and also a small amount coating
the exterior of the blow-off cap. This will help keep cooking
grease from building up on the cap.
NOTICE
When using a metal blow-off cap, make cer-
tain the spring clip rotates freely on the metal
cap.
Make certain a blow-off cap is in place over each nozzle
tip. These blow-off caps are designed to keep grease from
building-up on the nozzle orifice and inhibiting the agent
flow. See Figure 14.
FIGURE 14
SECTION V - INSTALLATION INSTRUCTIONS
UL EX. 3470 11-1-94 Page 5-8
r NSTALLING THE DETECTION SYSTEM
Before the following procedures can be completed, the detec-
tion design must already be completed. These installation
instructionsare identical for single, double, and multiple-tank
systems except for the number of hazard areas to be covered.
NOTICE
Inform customer that fusible links should not
be exposed to ammonia-based chemical
cleaners or steam.
Based on the requirements listed in the "System Design"
section, mount the detectors in their predetermined
locations.
Run 1/2 in. conduit from the regulated release mechanism
trip hammer assembly knockout hole to locations selected
for mounting thedetectors.
When changing the direction of conduit, use only Ansul
pulley elbows, except, at the top of the regulated release,
it is acceptable to use the "Conduit Offset Assembly" (Part
No. 79825).
Ansul offers three styles of detector bracket assemblies. Part
No. 56837 and 56838 are the "clip-on" style series and ter-
minal detector assemblies. These detector assemblies use
a "clip-on" style linkage assembly and do not require the
wire rope to be threaded through the linkage assembly while
it is being fed through the detection system.
Part No. 15373 and 15375 are the "hinged" style series
and terminal detector assemblies. These detector assem-
blies use a detector linkage assembly which requires the
wire rope to be threaded through each linkage assembly
while the rope is being fed through the detection system.
Part No. 417368 and 417369 are the "scissor" style series
and terminal detector assemblies. These detector assem-
blies use a detector linkage assembly which does not
require the wire rope to be threaded through the linkage
assembly while it is being fed through the detection system.
Installing "Clip-On" Style Linkage
1. Secure the conduit to the detector bracket using the two
1/2 in. steel compression fittings on the series detector
bracket or the single 1/2 in. steel compression fitting on the
terminal detector bracket. See Figure 15.

4. From the regulated release assembly, run the stainless steel
wire rope through theconduit, pulley elbows and detector
brackets to the terminal detector.
NOTICE
If wire rope requires splicing, make certain
splice is at least 12 in. (30.5 cm) away from
any pulley elbow or conduit adaptor to avoid
interference.
Feed the wire rope through the terminal detector bracket
as shown in Figure 18 or as shown in Figure 19 if the ter-
minal detector is mounted within a duct or header opening,
and install the stop sleeve approximately 2 to 3 in. (5 to 8
cm) from the end of the wire rope. See Figure 20. Use the
National Telephone Supply Company Nicopress Sleeve
Tool (Stock No. 51-C-887) or equal to properly crimp the
stop sleeve.
To give a constant tension on the wire rope during installa-
tion of the detector linkage, hang a vice grip or other
weighted device on the excess stainless steel wire rope,
leaving an adequate length of spare wire rope between the
locking clamp and the weighted device.
NOTICE
When attaching the weighted device to the
excess wire rope, allow approximately 3 in. (8
cm) of wire rope for each detector linkage for
proper installation.
Example: If the system has six detectors, there should be
approximately 18 in. (46 cm) of excess wire rope
between the locking clamp and the weighted
device, which will be utilized when the linkage
is put in place.
Starting at the terminal detector, place the small tab of the
detector linkage onto the wire rope. See Figure 21.

Use new pipe properly reamed and clean of metal
chips.
Install valve so that the actuator is above the horizontal
pipe line with no more than a five degree (50) lean either
way.
Make certain gas flow is in the same direction as arrow
shown on gas valve.
If strainer is utilized, attach strainer ahead of gas valve.
If necessary, install drip leg in gas line in accordance
with authority having jurisdiction.
For single-tank systems, install a 1/8 in. reducing fitting in
the top outlet of the regulator; double-tank systems require
an additional 1/4 in. nipple (4 in. long) and a 1/4 in. tee for
installation to the expellant gas piping. Attach remaining 1/8
in. fittings as required to facilitate piping requirements for
each pressure switch that will be used. See Figure 74.
NOTICE
Do not kink 118 in. copper tubing or form a
bend too close to a fitting. Secure each fitting

INSTALLING PRESSURE SWITCH
The procedure for field installing a pressure switch is as follows:
Make certain that regulated release assembly enclosure
cover is detached with lock bar properly inserted within the
release mechanism.
NOTICE
Failure to follow these instructions may lead
to system actuation.
Verify that cartridge has been removed from regulated
release assembly and that regulated release mechanism
is in the cocked position.
If regulated release mechanism does not have lock bar
inserted or cartridge removed, refer to the "Semi-Annual
Maintenance," Page 8-1, in "Maintenance Examination"
section, and complete Steps 2 and 3 before completing the
following installation steps.
Assemble pressure switch through knockout holes provided
on right side of regulated release assembly enclosure and
secure with a 1/2 in. nut, which is provided. See Figure 53.
If two pressure switches are required, preassemble the
switch enclosures using a 1/2 x 1 1/2 in. pipe nipple, 3/4
in. long spacer, and conduit nuts. The pipe nipple can be
used as a wiring chaseway. See Figure 74.
