STAINLESS STEEL CABLE The 1/16 in. stainless steel cable is run from the terminal detector, through conduit, all series detectors and pulley elbows, and into the regulated release mechanism trip lever. When any fusible link separates. the tension on the cable is relaxed, and the trip lever actuates the regulated release mechanism. The cable can also be used for mechanical gas valves and remote manual pull stations. The cable is available in 50 ft. (15 m) (Part No. 15821) and 500 ft, (152.4 m) (Part No, 79653) lengths, REMOTE MANUAL PULL STATION . The Remote Manual Pull Station (Part No, 4835 or Part No. 54011) is required for manual actuation of the regulated release assembly. The remote manual pull station should be mounted at a point of egress and positioned at a height determined by the · authority having jurisdiction. A brushed aluminum trim ring is avail- able for installation between the recessed junction box and the pull station. A package of 10 trim rings is available as Part No, 427074, PART NO. 4835 (WITHOUT CABLE) PART NO. 54011) (WITH 50 FT. OF CABLE) METAL STAMPED . FIGURE 23 000163 MECHANICAL GAS VALVES The mechanical gas valves are designed to shut off the flow of gas to the appliances upon actuation of the regulated release assem- bly. The valves are available in sizes of 3/4 in., 1 in., 1 1/4 in., 1 1/2 in., and 2 in. Ansul style; and 2 1/2 in. and 3 in. Asco style. The valves are rated for natural and LP gas. Both styles are UL Listed and includes the air cylinder. tubing, and fittings for connection to the release mechanism.

FIGURE 24 ELECTRICAL GAS VALVES The electrical gas valves are designed to shut off the flow of either natural or LP gas to the appliances upon actuation of the regulat- ed release assembly. The valves are available in sizes of 3/4 in., 1 in., 1 1/2 in., 2 in., and 3 in. The valve is held open by an ener- gized solenoid and upon system actuation, the switch contacts in the regulated release assembly open, thus de-energizing the cir- cuit to the gas valve solenoid, causing the valve to close. Valves are available in 120 VAe and are UL Listed. Part Maximum Operating No, !?~~E!:iP~~~ ~.!:~~~~~________ · 13707 3/4 in. Solenoid Gas Valve (AS eO) 2 psi (.14 bar) 13708 1 in.
