DESCRIPTION

Kidde Argonite

Fire Protection Systems are clean

agent, automatic extinguishing systems that use Argonite

(IG-55) and consist of four basic components and their

associated accessories:

• Argonite Cylinders and Components,

• Completer Kits,

• Control Panels,

• Detection and Alarm Devices.

Argonite is an inert gas mixture, in equal parts, of Nitro-

gen and Argon. Both substances are naturally occurring

and present in the atmosphere. Argonite is safe for use in

occupied spaces and poses no threat to the environment.

1. Argonite Components consist of the agent cylinders,

cylinder racking and the agent discharge nozzles.

2. The Completer Kits provide all the basic compo-

nents necessary to operate the Argonite cylinders.

The kits consist of hoses, connection fittings, pres-

sure gauges, actuation devices required to operate

the cylinder valve and warning signs to be displayed

in the area(s) protected by an Argonite fire extin-

guishing system.

3. The Control Panels vary in features and complexity

but in all cases are used to monitor the detection,

actuate the alarms, initiate the agent discharge and

control auxiliary functions such as shut down of vital

equipment and ventilation dampers.

4. The Detection and Alarm devices provide fire detec-

tion by means of thermal or smoke detectors, audi-

ble and visual pre-alarm warnings and annunciation

of the Argonite discharge.

AGENT DESCRIPTION

Argonite is a mixture of 50% pure Nitrogen and 50% pure

Argon. Argonite contains only naturally occurring sub-

stances, and as such, has no ozone depletion potential

and no direct global warming potential.

Argonite extinguishes by means of reducing the oxygen

content within a room to the point at which fire can no

longer burn, but without compromising the safety of indi-

viduals present. There are no toxicological factors asso-

ciated with the use of Argonite. Argonite will not

decompose or produce any by-products when exposed

to a flame from a fire condition.

Most Argonite systems are designed to extinguish fires

with a minimum agent concentration of 37.9% achieved

within one minute. This results in extinguishment of the

fire and an oxygen concentration of 13%.

Argonite is stored as a gas within the cylinder assembly.

It is available at a storage pressure of 2900 PSI (200

bar).

1. Manual/Pneumatic Actuator Connection: Each cylinder valve must be fitted with either a Pilot or Slave type actuator. SIDE VIEW HANDLE FOR FILLING ONLY The Pilot actuator provides a manual (pull pin turn handle) actuator and connections from an electrical solenoid and pressure switch assembly. The pilot actuator also has connections to adjacent slave cylinder actuators to discharge entire groups of cylinders virtually simultaneously. M25 x 1.

SOLENOID AND PRESSURE GAUGE ASSEMBLY WITH SUPERVISORY PRESSURE SWITCH The solenoid/pressure gauge assembly provides an electrical means (24 Vdc) of actuating the system as well as a visual means to determine the pressure within the pilot cylinder. PILOT FLEX HOSE #1, P/N 38-509818-001 This 1/4-inch ID reinforced rubber flex hose has threaded connections to allow interface between the pilot cylinder solenoid/pressure gauge assembly and pilot manual/ pneumatic actuator.
PAGE 5
TEE PIECE FOR HOSE CONNECTIONS, P/N 38-509816-001 The tee piece is supplied with each of the completer kits. It provides the interface with the pilot assembly (through a high pressure flex hose) to simultaneously operate the slave cylinder pneumatically. DISCHARGE FLEX HOSE, P/N 38-509819-001 This flex hose has 1/2-inch threaded connections to allow interface between the cylinder valves and the discharge manifold (if applicable).

FLOW RESTRICTOR The restrictor assembly reduces the initial Argonite pressure from the discharge manifold to between 174 and 870 PSI (12 and 60 bar) before entering the discharge piping. The size of the orifice within the restrictor is determined through calculations based upon the required flow and discharge time. NPT CONNECTION FOR DISTRIBUTION PIPE WORK 38-XX0003-XXX Larger diameter restrictors, up to 4 in. (102 mm) connection, are available for very large system requirements.

SELECTOR VALVES Argonite systems are particularly suited to the use of selector valves, where one central storage of agent is used to provide protection to two or more hazard areas. Selector valves are available in six sizes, and are pneumatically operated. One common pressure regulator and vented elbow are also required to reduce the actuation pressure to each set of selector valves.
