VALVE CONTROLS.
1-18.
LOCAL MANUAL RELEASE. Local manual operation is obtained by a lever operated device mounted to the pilot
port of the valve. See K-4020.
1-19.
REMOTE MANUAL RELEASE. The remote activation of the cylinder valve is accomplished through the break
glass pull box, Z-Bracket, 1/16" stainless steel cable and corner pulleys interconnected with 3/8" steel pipe. The two
break glass pull boxes are connected to the cable operated control head through the dual pull mechanism. See K-4040,
K-4041,K-4080, K-4100 and K-4020.
1-20.
STOP VALVE. Release of Halon 1301 from the manifold is control by the 11/2" stop valve. See K-3070.
1-21.
LEVER OR PRESSURE OPERATED CONTROL HEAD. The stop valve is operated when the lever or pressure
operated control head is operated in either the lever or pressure mode. See K-3150.
1-22.
LEVER OPERATED CONTROL HEAD. The discharge delay can be manually overridden by operation of the
attached lever operated control head. See K-4010.
1-23.
CONTROL AND WARNING DEVICES.
1-24.
DISCHARGE DELAY. The operation of the stop valve is delayed for a minimum of twenty seconds by the
discharge delay. See K-3190 and K-3191.
1-25.
PRESSURE OPERATED SIREN. The siren provides an audible predischarge warning to personnel in void 4 port
or starboard. See K-3200.
1-26.
ACCESSORY EQUIPMENT.
1-27.
PRESSURE OPERATED SWITCH. This device operates from Halon pressure when the cylinder valve opens. A
built-in switch changes position to de-energize void 4 ventilation fan circuits and shut-down machinery. See K-3160.
1-28.
DISCHARGE INDICATOR. This device has an indicating plunger that is moved from a normal (non-visual)
position to a discharged indication position when Halon pressure is present in the manifold. See K-3110.
1-29.
SAFETY OUTLET. This device provides an over-pressure relief at between 750-900 PSI. See K-3120.
