AUTOPULSE Control System

Description

The AUTOPULSE Control System consists of a micro-processor based panel field programmable for cross-zone, counting-cross-zone, independent or priority-zone (counting) detection circuit applications. Several models of the AUTOPULSE Control System are available depending on the type of hazard being protected.

CV90/MAX Valve Stackable/Lever Actuator

Description

Stackable Actuator – MAX Valve Only: The stackable

actuator is required to attach a valve actuation component to the MAX valve. The slave back-pressure actuator, which comes installed as part of the MAX valve, must be removed in order to attach the stackable back-pressure actuator. In one and two-cylinder systems, one stackable back-pressure actuator is required to attach a valve actu-ation component. In a two cylinder system, the remaining cylinder is actuated by the pressure generated within the distribution manifold.

In three or more cylinder systems, two stackable back-pressure actuators are required to attach valve actuation components. The remaining cylinder(s) is actuated by the pressure generated within the distribution manifold.

Lever Release Actuator – CV90/MAX Valve: The

manu-al lever release actuator provides a manumanu-al means of agent cylinder actuation by direct manual actuation of its pull lever or cable actuation when used in conjunction with a remote manual pull station.

In three or more cylinder systems, a connecting link is required to provide simultaneous actuation of both manu-al cable-pull actuators.

Manual actuation is accomplished by pulling the valve hand lever. The lever design contains a forged mechani-cal detent which secures the lever in the open position when actuated.

Cable-pull actuation is accomplished by using a remote manual pull station. The remote manual pull station sys-tem must contain the components necessary to meet the actuator lever traveling requirements of 7 in. (17.8 cm).

Sealed Nozzle With Strainer

Description

The sealed nozzle is used primarily in ducts and enclosed machinery spaces. The seal portion of the nozzle is a combination line seal and strainer unit. It is used to pre-vent dirt or vapors from entering the system piping and also to function as a strainer for the system piping. On operation of the carbon dioxide system, the high pressure of the gas released from the cylinders ruptures the thin

sealing disc, allowing an unobstructed flow of gas to the internal discharge nozzle.

The advantage of the sealed nozzle is that it does not require disassembly of the system piping to clean the strainer or replace a ruptured sealing disc. This is accom-plished by removing the hex cap on the nozzle.

Bulkhead Mounting Flange

Description

The bulkhead mounting flange, Part No. 42806, is used on the multi-discharge type nozzles. The flange allows the nozzle to be rigidly fastened against a wall or bulkhead of a hazard area, keeping the nozzle outside of the area. This is an advantage on hazard areas where the nozzle cannot be mounted inside the area because of space limi-tations or interference with moving parts. A typical appli-cation is a large exhaust duct where access into the duct is limited.

Also available is a sealing plug, Part No. 42293, which is shipped as a separate unit.

Should a seal be required between the flange and the mounting surface, the fiber seal, Part No. 36550, is avail-able.

Discharge Nozzle – Baffle Type

Description

The baffle type nozzle is used in total flood applications only. Placed around the outside edge or placed near the ceiling approximately 15 to 20 ft. (4.6 to 6.1 m) on centers in a room or any enclosed space, each nozzle provides a 180° fan spray of CO2, spreading the extinguishing gas quickly and efficiently throughout the protected

space. Discharge rate depends upon nozzle pressure and orifice size. Baffle type nozzles are available in orifice sizes 1 through 16.

This nozzle is supplied in natural brass with chrome or nick-el plating available as an option.

Lever Release Actuator AP-8 Valve/Selector Valve

Description

Lever Release Actuator: The manual lever release

actua-tor can provide a manual means of agent cylinder actuation by direct manual actuation of its pull lever or cable actua-tion when used in conjuncactua-tion with a remote manual pull station.

In three or more cylinder systems, a connecting link is required to provide simultaneous actuation of both lever release actuators.

Manual actuation is accomplished by pulling the valve hand lever. The lever design contains a forged mechanical detent which secures the lever in the open position when actuated. Cable pull actuation is accomplished by using a remote manual pull station. The remote manual pull station

system must provide the components necessary to meet the actuator lever traveling requirements of 7 in. (17.8 cm). Manual actuation for electric or pneumatic selector valves can be accomplished using these lever actuators.
