<br />SECTION III - SYSTEM COMPONENTS <br />UL EX. 5174 8-1-99 Page 3-2 <br />REV. 2 <br /> <br />. 101 REMOTE MECHANICAL RELEASE <br /> <br />The 101 Remote Mechanical Release, Part No. 32381, is used to <br />actuate up to five (5) PIRANHA regulated actuators. The 101 <br />remote mechanical release utilizes a 101-10 carbon dioxide car- <br />tridge, Part No. 15850, as the actuation pressure to operate the <br />PIRANHA regulated actuators. The remote release assembly con- <br />tains an external strike button for manual actuation. <br /> <br />o <br /> <br />o <br /> <br />STRIKE <br />BUTTON <br /> <br /> <br />RELEASE <br />MECHANISM <br /> <br />, <br />r <br />I <br />, <br />I <br />1 <br />I <br />I <br />I <br />I <br />I <br />I <br />\ <br />o ,__/ 0 <br /> <br />. FIGURE 4 <br />004205 <br /> <br />REGULATED ACTUATOR ASSEMBLY <br /> <br />The Regulated Actuator Assembly. Part No. 423368. contains the <br />regulator, water flow valve, anti-siphon vacuum breaker, pneumat- <br />ic actuator, water pressure test outlet, expellant gas hose for agent <br />tank hookup, and enclosure knockouts to facilitate installing expel- <br />lant piping. This assembly is used in multiple-tank systems and <br />must be mounted to a rigid surface. <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. <br /> <br />Agent tanks must be purchased separately and must be mounted <br />within the enclosure. The enclosure contains a knockout to facili- <br />tate distribution piping hookup. <br /> <br />REGULATED ACTUATOR ASSEMBLY <br /> <br />. <br /> <br />WATER INLET <br /> <br /> <br />HIGH <br />PRESSURE <br />LINE <br /> <br />o rSo..::~ <br /> <br />_~,:="'i!; <br />... - ANTI-SIPHO;-.... <br />VACUUM <br />BREAKER <br /> <br />ACTUATOR <br /> <br />REGULATOR <br /> <br />WATER <br />FLOW <br />VALVE <br /> <br />LOW <br />PRESSURE <br />LINE (TO <br />AGENT TANK <br />ADAPTOR) <br /> <br /> <br />o <br /> <br />() <br /> <br />WATER LINE (TO AGENT TANK ADAPTOR <br /> <br />FIGURE 5 <br />001595 <br /> <br />MECHANICAL REGULATED RELEASE ASSEMBLY WITH <br />OEM BRACKET <br /> <br />The Mechanical Regulated Release Assembly with OEM Bracket, <br />Part No. 423629, contains the same release mechanism and <br />water flow components as the standard mechanical regulated <br />release assembly without being housed in a stainless steel enclo- <br />~u~e.
