<br />SECTION III - SYSTEM COMPONENTS <br />UL EX. 3470 ULC CEx747 Page 3-2 <br />REV. 3 10-1-02 <br /> <br />~ SINGLE TANK ENCLOSURE ASSEMBLY <br /> <br />~ The Single Tank Enclosure Assembly (Part No. 429870) is used in <br />double and multiple-tank systems and must be mounted to a rigid <br />surface near the regulated release or regulated actuator assembly <br />its expellent gas line will be connected to. <br /> <br />~ The enclosure is designed for mounting either a 1.5 gallon (Part <br />~ No. 429864) or a 3.0 gallon tank (Part No. 429862) in a minimum <br />amount of space. <br /> <br />ENCLOSURE ASSEMBLY <br /> <br />NarE: AGENT TANK MUST <br />BE ORDERED <br />SEPARATELY <br />~ OR SEE PAGE 3-4 <br /> <br /> <br />MOUNTING _ <br />ENCLOSURE <br /> <br />~ <br /> <br />SHIPPING WT. <br />13 LB. (6 kg) <br /> <br />CJ <br /> <br /> <br />FIGURE 4 <br />000142 <br /> <br />~ RED PAINTED BRACKET ASSEMBLY <br /> <br />The Bracket Assembly (Part No. 429878) is used in double and <br />multiple-tank systems and must be mounted to a rigid surface near <br />the regulated release assembly or regulated actuator assembly <br />that its expellant gas line will be connected to. <br /> <br />~ The tank bracket is constructed of mild steel and painted red. It is <br />I designed for mounting the tank in a minimum amount of space. <br />The Bracket Assembly can only be utilized with 3.0 gallon tanks <br />~ (Part No. 429862). <br /> <br />BRACKET ASSEMBLY <br /> <br /> <br />MOUNTING <br />BRACKET <br /> <br />~ <br /> <br />SHIPPING WT. 7 LB. (3 kg) <br /> <br />FIGURE 5 <br />000141 <br /> <br />REGULATED ACTUATOR ASSEMBLY <br /> <br />The Regulated Actuator Assembly (Part No. 429850) contains the <br />regulator, pneumatic actuator, expellant gas hose for agent tank <br />hookup (agent tank must be ordered separately), and enclosure <br />knockouts to facilitate installing expellant piping. This assembly is used <br />in multiple-tank systems and must be mounted to a rigid surface. <br /> <br />The regulator contains two outlets 1350 apart. One outlet is used <br />to interconnect the expellant gas hose to the enclosed agent tank. <br />The other outlet connects an expellant gas line to an additional <br />enclosure or bracket assembly. The regulator is designed to allow <br />a constant flow of nitrogen into each agent tank connected (two <br />tanks maximum) at 110 psi (759 kPa). <br /> <br />The pneumatic actuator is designed to puncture the expellant gas <br />cartridge seal upon receiving pressure from the regulated release <br />assembly actuation piping. The enclosure contains a knockout to <br />facilitate distribution piping hookup. <br /> <br />REGULATED ACTUATOR ASSEMBLY <br /> <br />NOTE: AGENT TANK <br />MUST BE <br />ORDERED <br />SEPARATELY <br />~ OR SEE PAGE 3-4 <br /> <br /> <br />~ <br /> <br />PNEUMATIC <br />ACTUATOR <br />ASSEMBLY <br /> <br />REGULATOR <br /> <br />~ <br /> <br />SHIPPING WT. <br />19 LB. (9 kg) <br /> <br />FIGURE 6 <br />000'43 <br /> <br />AGENT TANK ASSEMBLY <br /> <br />The agent tank shipping assembly (3-Gallon, Part No. 429862, <br />~ and 1.5 Gallon, Part No. 429864) consists of a stainless steel tank <br />and an adaptor/tube assembly. The adaptor/tube assembly con- <br />tains a burst disc. The burst disc prevents agent leakage due to <br />significant temperature fluctuations in the area where the tank is <br />located. Under normal conditions, the tank requires hydrostatic <br />testing every twelve years. The date of manufacture is stamped on <br />the tank nameplate. <br /> <br />The tank is shipped uncharged and must be filled with only <br />ANSULEX Low pH Liquid Fire Suppressant during installation. <br /> <br />" <br /> <br />~ <br /> <br /> <br />FIGURE 7 <br />000140 <br /> <br />~ <br /> <br />3 GALLON <br />SHIPPING WT. <br />7 LB.
