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. (Refer to Section V,
Page 5-2.1, for maximum agent fill capacity.) Agent storage life
expectancy is twelve years and can be stored at a temperature of
—40 OF to 130 °F (-40 °C to 54 °C). Note: When installing agent
in R-102 system, temperature range is 32 °F (0 °C) to 130 °F
(54 °C). The distributor must record the batch numbers and date
of shipment receipt to be filed with each installation record.

REGULATED RELEASE ASSEMBLY (MECHANICAL)
The AUTOMAN Regulated Mechanical Release Assembly (Part
No. 429853) contains the regulated release mechanism, expel-
lant gas hose for agent tank hookup, and enclosure knockouts
to facilitate installing actuation piping; expellant piping; detec-
tion system; and additional equipment. This regulated release
assembly is used in single, double, and multiple -tank systems
and must be mounted to a rigid surface. The release mecha-
nism can be used to interconnect both the actuation and expel-
lant gas lines as required per system design. The regulator is
designed to allow a constant flow of gas into the tank at 110 psi
(7.6 bar) when the system is actuated. The agent tank must be
ordered separately.
In single, double, and multiple -tank systems, the provided
expellant gas hose connects the agent tank to the bottom outlet
of the regulator. In double and multiple -tank system configura-
tions, 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 connection. 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
significant temperature fluctuations in the area where the tank
is located. The tank is stainless steel and, under normal condi-
tions, requires hydrostatic testing every twelve years.
The detection and additional equipment required per system
design are connected to the release mechanism. The enclosure
contains knockouts to facilitate detection and additional hookups.

REGULATED RELEASE ASSEMBLY (ELECTRICAL)
The AUTOMAN Regulated Electrical Release Assembly (Part
No. 429856) is identical to the mechanical version except it also
contains a factory installed 120 VAC solenoid and electrical
switch.
The solenoid is used to provide electrical actuation of the
release mechanism. The electric switch is used to protect the
solenoid by opening the circuit to the solenoid once the system
is fired. Additional electrical switches can be added as required
for automatic equipment and gas shut-off accessories, as well
as initiating audible and visual alarms.

TWO TANK ENCLOSURE ASSEMBLY
The Two Tank Enclosure Assembly (Part No. 429872) consists
of two expellant gas hoses, two grommets, and the mounting
enclosure. The assembly is used in 9-gallon systems. It can be
coupled with a 3-gallon regulated release assembly or a 3-gal-
[on regulated actuator assembly to give a total of 9 gal (34.1 L)
of agent. Agent tanks must be ordered separately.
The tank enclosure is designed to mount in a minimum amount
of space.

► 24VDC REGULATED RELEASE ASSEMBLY
The 24VDC Regulated Release Assembly (Part No. 429859) is
used where electric, thermostat detection is required via the use
of a releasing control unit. This assembly consists of a 24VDC
AUTOMAN II-C regulated release mechanism, expellant gas
hose, and enclosure knockouts to facilitate installing actuation
piping, expellant piping, detection system, and additional equip-
ment. Agent tank must be ordered separately.
The system can be actuated automatically or manually.
Automatic actuation occurs when the control panel receives
a signal from the detection circuit. The panel then sends an
electrical signal to the 24VDC regulated release, causing it to
actuate. When actuation occurs, the gas cartridge is punctured,
pressurizing the agent tank and discharging the agent through
the distribution piping. Manual actuation of the system occurs
when personnel pull on the remote manual pull station pull ring.

GAS CARTRIDGES
The R-102 system uses gas cartridges to store nitrogen or
carbon dioxide expellant gases under pressure until the system
is actuated, at which time the cartridge seal is punctured and
the released gas expels liquid agent from one or more tanks
through the discharge piping and out the discharge nozzles.
Four nitrogen gas cartridges and three carbon dioxide gas car-
tridges are available as shown in Figure 13.
Cartridges noted as TC/DOT are both Transport Canada (TC)
and Department of Transportation (DOT) approved. Cartridges
noted as DOT are Department of Transportation approved only.

REMOTE MANUAL PULL STATION
The remote manual pull station (Part No. 434618 or 435960)
is made out of a molded red composite material. The red color
makes the pull station more readily identifiable as the manual
means for fire suppression system operation. The pull station
is compatible with the ANSUL Flexible Conduit. The molded
manual pull station should be mounted at a point of egress
and positioned at a height determined by the authority having
jurisdiction. Trim Rings (Part No. 427074) (pack of 10), are
available.

DUCT SIZES GREATER THAN 100 IN. (2540 mm)
PERIMETER
• Ducts over 100 in. (2540 mm) perimeter may be modularized
using 2W nozzles
• No round duct option available
• Follow the design chart to determine maximum module size
for each 2W nozzle
• When determining number of nozzles required, it is sometimes
an advantage to check the chart using the shortest side as
Side "A" and then recheck it using the longest side as Side
"A." This comparison may reveal a need for a lesser quantity
of nozzles one way versus the other way.
When working with Chart 4-1, the quantity of nozzles deter-
mined must be equally divided within the duct area.

When working with Chart 4-2, one half of the quantity of nozzles
determined must be equally positioned in the top half of the
area of the duct and the remaining half of the nozzles must be
positioned in the bottom half of the duct area.
Example: The duct to be protected has a Side "A" of 40 in.
(1016 mm) and a Side "B" of 60 in. (1524 mm). Referring to the
design chart, this duct requires four nozzles. One half of 4 = 2.
Therefore, two nozzles must be equally positioned in each of the
two duct areas. See Figure 4-3.

One 1 W nozzle will protect 6 linear feet (1.8 m) of "V" bank
plenum. The nozzle must be mounted horizontally, positioned 1/3
the filter height down from the top of the filter. Nozzles can be
located at 6 ft (1.8 m) spacings on longer plenums. The nozzle
must be positioned 0-6 in. (0-152 mm) from the end of the hood to
the tip of the nozzle. See Figure 4-10.

TWO 1 N NOZZLES — "V" BANK PROTECTION
R-102 Restaurant Fire Suppression Manual
For a plenum, either single or "V" bank, with a linear extension
► longer than 10 ft (3.0 m), each bank may be protected using one
► 1 N nozzle every 10 ft (3.0 m) or less depending on the overall
length of the plenum. See Figure 4-12. The nozzles may point
in the opposite directions as long as the entire plenum area is
► protected, and the 10 ft (3.0 m) limitation is not exceeded. See
Figure 4-13. The nozzle positioning shown in Figure 4-14 is not
an acceptable method of protection because the plenum area
directly under the tee is not within the discharge pattern of either
nozzle.
► Two 1 N nozzles will protect 10 linear feet (3.0 m) by 4 ft (1.2 m)
wide of "V" bank plenum. The nozzles must be mounted in the '
P. plenum, 2 to 4 in. (50 to 101 mm) from the face of the filter,
centered between the filter height dimension, and aimed down the
length. The nozzle must be positioned 0-6 in. (0-381 mm) from the
end of the hood to the tip of the nozzle. See Figure 4-11.
