- Manufacturer:
Ansul Fire Protection
One Stanton Street
Marinette, Wisconsin 54143-2542
Telephone (715) 735-7411
- Components:
The basic system shall consist of an
ANSUL AUTOMAN regulated release assembly which includes a regulated release mechanism and
a wet chemical storage tank housed within a single enclosure. Nozzles, blow-off caps,
detectors, cartridges, agent, fusible links, and pulley elbows shall be supplied in
separate packages in the quantities needed for fire suppression system arrangements.
Additional equipment shall include remote manual pull station, mechanical and electrical
gas valves, pressure switches, and electrical switches for automatic equipment and gas
line shut-off.
- Wet Chemical Agent:
The extinguishing agent shall
be a specially formulated, aqueous solution of organic salts with a pH range between 7.8 -
8.2, designed for flame knockdown and foam securement of grease related fires.
- Agent Tank:
The agent tank shall be installed in a
stainless steel enclosure or wall bracket. The tank shall be deep drawn carbon steel
finished in red enamel. Tanks shall be available in two sizes; 1.5 gallon (5.7 L) and 3.0
gallon (11.4 L).The tanks shall have a working pressure of 100 psi (6.9 bar), a test
pressure of 300 psi (20.7 bar), and a minimum burst pressure of 600 psi (41.4 bar). The
tank shall include an adaptor/tube assembly containing a burst disc union.
- Regulated Release Mechanism:
The regulated release
mechanism shall be a spring-loaded, mechanical/pneumatic type capable of providing the
expellant gas supply to one or two agent tanks depending on the capacity of the gas
cartridge used. It shall contain a factory installed regulator deadset at 100 psi (6.9
bar) with an internal relief of approximately 145 psi (10.0 bar). It shall have the
following actuation capabilities: automatic actuation by a fusible link detection system
and remote manual actuation by a mechanical pull station. The regulated release mechanism
shall contain a release assembly, regulator, expellant gas hose, and agent storage tank
housed in a stainless steel enclosure with cover. The enclosure shall contain knock-outs
for 1/2 in. conduit. The cover shall contain an opening for a visual status indicator.It
shall be compatible with mechanical gas shut-off devices; or, when equipped with a field
or factory-installed switch, it shall be compatible with electric gas line or appliance
shut-off devices.
- Regulated Actuator Assembly:
When more than two
agent tanks are required, the regulated actuator shall be available to provide expellant
gas for additional tanks. It shall be connected to the cartridge receiver outlet of the
regulated release mechanism providing simultaneous agent discharge. The regulator shall be
deadset at 100 psi (6.9 bar) with an internal relief of approximately 145 psi (10.0 bar).
The regulated actuator assembly shall contain a regulated actuator, regulator, expellant
gas hose, and agent tank housed in a stainless steel enclosure with cover. The enclosure
shall contain knockouts to permit installation of the expellant gas line.
- Discharge Nozzles:
Each discharge nozzle shall be
tested and listed with the R-102 system for a specific application. Nozzles tips shall be
stamped with the flow number designation (1/2, 1, 2, and 3). Each nozzle shall have a
metal or rubber blow-off cap to keep the nozzle tip orifice free of cooking grease
build-up.
- Distribution Piping:
Distribution piping shall be
Schedule 40 black iron, chrome-plated, or stainless steel pipe conforming to ASTM A120,
A53, or A106.
- Detectors:
The detectors shall be the fusible link
style designed to separate at a specific temperature.
- Cartridges:
The cartridge shall be a sealed steel
pressure vessel containing either carbon dioxide or nitrogen gas. The cartridge seal shall
be designed to be punctured by the releasing device supplying the required pressure to
expel wet chemical agent from the storage tank.
|
|
|
- Installation:
The R-102 fire suppression system
shall be designed, installed, inspected, maintained, and recharged in accordance with the
manufacturer's listed instruction manual.
- Training:
Training shall be conducted by
representatives of the manufacturer.
