<br />EXTINGUISHING AGENT <br /> <br />PRXTM Liquid Fire Suppressant, Part No. 423320, is a specially- <br />formulated, aqueous solution of inorganic salts designed for fast <br />knock-down and suppression of grease-related fires. The agent is <br />shipped in a translucent 5.0 gallon (18.9 L) plastic container. The <br />agent is colored red for easy identification. Agent storage life <br />expectancy is twelve years. <br /> <br />PRX LIQUID FIRE SUPPRESSANT <br /> <br /> <br />5,0 GALLON (18.9 L) PAIL <br /> <br />FIGURE 1 <br /> <br />REGULATED RELEASE ASSEMBLY (MECHANICAL) <br /> <br />The ANSUL AUTO MAN Regulated Mechanical Release Assembly, <br />Part No. 423477, contains the regulated release mechanism, water <br />flow valve, anti-siphon vacuum breaker, water pressure test outlet, <br />expellant gas hose for agent tank hookup, and enclosure knock- <br />outs to facilitate installing actuation piping; expellant piping; detec- <br />tion system; and additional equipment. This regulated release <br />assembly must be mounted to a rigid surface. The release mecha- <br />nism can be used to interconnect both the actuation and expellant <br />gas lines as required per system design. The regulator is designed <br />to allow a constant flow of gas into the tank at 150 psi (10.3 bar) <br />when the system is actuated. <br /> <br />The assembly is shipped with two factory installed single-pole, <br />double throw (SPOT) electrical switches. <br /> <br />Agent tanks must be purchased separately and must be mounted <br />within the enclosure. <br /> <br />The detection and additional equipment required per system <br />design are connected to the release mechanism. The enclosure <br />contains knockouts to facilitate detection and additional hookups, <br /> <br />The system can be actuated automatically or manually. Automatic <br />actuation occurs when a fusible link within the detection system <br />separates in a fire condition. Manual actuation of the system <br />occurs when personnel pull on the remote manual pull station <br />pull ring. <br /> <br />SECTION III - SYSTEM COMPONENTS <br />UL EX. 5174 8-1-99 Page 3-1 <br />REV. 2 <br /> <br /> <br />ANSUL AUTO MAN REGULATED RELEASE ASSEMBLY <br />(MECHANICAL) <br /> <br />~ <br /> <br />0[.....- I <br />___e _ <br />- ANTI-SIPHON --, <br />VACUUM <br />BREAKER <br /> <br />WATER <br />FLOW <br />VALVE <br /> <br />REGULATOR <br /> <br /> <br />o <br /> <br />001606 <br /> <br />WATER LINE (TO <br />AGENT TANK ADAPTOR) <br /> <br />~ <br /> <br />RELEASE <br />MECHANISM <br /> <br />HIGH <br />PRESSURE <br />HOSE <br /> <br />LOW <br />PRESSURE <br />HOSE (TO <br />AGENT TANK <br />ADAPTOR) <br /> <br />FIGURE 2 <br /> <br />001693 <br /> <br />REGULATED RELEASE ASSEMBLY (ELECTRICAL) <br /> <br />The ANSUL AUTO MAN Regulated Electrical Release Assembly, <br />Part No. 423386, is identical to the mechanical version except it <br />contains a factory installed 120 VAC solenoid and two single-pole, <br />double throw (SPOT) electrical switches. <br /> <br />The solenoid is used to provide electrical actuation of the release <br />mechanism. The electric switch is used to protect the solenoid by <br />opening the circuit to the solenoid once the system is fired. <br />Additional electrical switches can be added as required for auto- <br />matic equipment and gas shut-off accessories, as well as initiating <br />audible and visual alarms. <br /> <br /> <br />"ANSUL AUTOMAN" REGULATED RELEASE ASSEMBLY <br />(ELECTRICAL) <br /> <br />~ <br /> <br />WATER <br />FLOW <br />VALVE <br /> <br /> <br />'" <br /> <br />~ <br /> <br />WATER LINE (TO <br />AGENT TANK ADAPTOR) <br /> <br />RELEASE <br />MECHANISM <br /> <br />SOLENOID <br /> <br />HIGH <br />PRESSURE <br />HOSE <br /> <br />LOW <br />PRESSURE <br />HOSE (TO <br />AGENT TANK <br />ADAPTOR) <br /> <br />FIGURE 3 <br />oo1f194 <br />
