1-11. SYSTEM COMPONENT. The Halon 1301 System installed in the ROWPU BARGE is made up of the following components: Two 312 pound capacity cylinders and valve assembly (P/N 897793) each filled with 290 pounds of Halon 1301 and super pressurized to 360 PSI at 70F. One cylinder is a spare and is not connected to the system. The primary Halon cylinder is piped to a discharge manifold, the cylinders are held in place by straps (P/N 281866). The manifold components are a discharge delay (minimum delay 20 sec.) (P/N 896677), discharge indicator, (P/N 875553), safety outlet 3/4" (P/N 844346), lever operated control head (P/N 870653), pressure/lever operated control head (P/N 870897), 3/8" flex loop (P/N 844226), pressure operated switch (P/N 873752), 1¹/2" stop valve (P/N870123) and a safety outlet (P/N 844346). Other components are: two pressure operated sirens (P/N 981574) located in void 4 port and starboard, two split fan discharge nozzles (P/N 29474463) located in void 4 port and starboard. The control/activation mechanism is composed of two manual pull boxes (P/N 871403) held in place by pull box bracket (P/N 60532) and connected to the cable operated control head (P/N 979469) by a 1/16" stainless steel cable through a series of corner pulleys (P/N 803808) and a dual pull mechanism (P/N 840058). 1-12. DESCRIPTION OF COMPONENTS. 1-13. CYLINDER AND VALVE ASSEMBLY. This assembly provides for storage of the Halon 1301 agent under a super pressurization of nitrogen of 360 psig at 70F. SeeK-2020, K-2080. 1-14. Steel alloy cylinders are used which comply with DOT Specification 4BA having a service rating of 500 psig and a minimum burst pressure of 2000 psig. 1-15. An aluminum valve assembled to the cylinder allows for leak tight storage of the agent in the standby condition. Release of the agent occurs when the valve control is energized by manual means. See K2050. 1-16. A pressure gage and a burst disc safety device are incorporated as an integral part of the cylinder valve. The pressure gage monitors the charge pressure of the agent supply. Protection against over pressurization is provided by the safety device which will relieve at between 750 and 900 psig. See K-2060.
