2.0 PRODUCT 3.0 IMPLEMENTATION 2.2 Components (Continued) 2.2.3 Agent Tank: The agent tank shall be installed in a stainless steel enclosure. The tank shall be deep drawn carbon steel finished in red enamel. Tanks shall be available in three (3) sizes; 1.5 gallon (5.7 L), 2.25 gallon (8.5 L), and 3.0 gallon (11.4 L). The tanks shall have a working pressure of 150 psi (10.3 bar), a test pressure of 450 psi (31.0 bar). and a minimum burst pressure of 900 psi (62.1 bar). The tank shall include an adaptor/tube assembly containing a burst disc union. 2.2.4 Tank Valve: The tank valve shall be designed to discharge dual agent onto the hazards being protected. The valve shall automatically shuttle to switch from wet chemical agent discharge to water discharge. 2.2,5 Regulated Release Mechanism: The regulated release mechanism shall be a spring-loaded. mechanical/pneumatic type capable of providing the expellant gas supply via a pressurized cartridge to a single agent tank. It shall contain a factory installed regulator deadset at 150 psi (10.3 bar) with an intemal relief of approximately 190 psi (13.1 bar). It shall have automatic actuation by a fusible link detection system and remote manual actuation by a mechanical pull station. The regulated release mechanism shall contain a release assembly, regulator, expellant gas hose. anti-siphonage valve. and agent storage tank housed in a stainless steel enclosure with cover. The enclosure shall contain knock-outs for 1/2 in. conduit. The cover shall contain an opening for a visual status indicator. It shall be compatible with mechanical gas shut-off devices; or when equipped with a field or factory- installed switch. it shall be compatible with electric gas line or appliance shut-off devices. 2.2,6 Discharge Nozzles: Two types of discharge nozzles shall be tested and listed with the PIRANHA system for all applications. One type shall be used for all high proximity appliance and plenum protection and shall be stamped "AP: The other type shall be used for all duct and low proximity appliance protection and shall be stamped "DL." Each nozzle shall have a metal or rubber blow-off cap to keep the nozzle tip orifice free of cooking grease build-up. 2.2.7 Distribution Piping: Distribution piping shall be Schedule 40 black iron, chrome-plated. or stainless steel pipe conforming to ASTM A120, A53. or Al06. 2.2.8 Detectors: The detectors shall be the fusible link type designed to separate at a specific temperature. 2.2.9 Cartridges: The cartridge shall be a sealed steel pressure vessel containing nitrogen gas. The cartridge seal shall be designed to be punctured by the releasing device supplying the required pressure to expel the wet chemical agent from the storage tank, 2.2.10 Water supply piping: The water supply piping portion of the dual agent system shall contain a lockable ball valve, The lockable ball valve shall be installed in the water supply piping to allow authorized per- sonnel to close the valve after a system actuation and stop the flow of water into the hazard area. 2.2.11 Water shutdown device: With the approval of the AHJ, a water shutdown device shall be installed in the water supply piping, This device shall automatically shutdown the flow of water to the discharge nozzles approximately 10 minutes after system actuation. 3.1 Installation 3.1.1 The PIRANHA fire suppression system shall be designed, installed. inspected, maintained, and recharged in accordance with the manufacturer's listed instruction manual. 3.2 Training 3.2.1 Employees shall be instructed in personal safety and the operation of the system by authorized distributors who are trained by the manufacturer. i .
