EXTINGUISHING AGENT , ANSULEX Low pH Liquid Fire Suppressant (1.5 gallon - Part No. 79694 or 3.0 gallon - Part No. 79372) is a potassium-based solu- tion designed for fast knock-down and suppression of grease- related fires. The agent is shipped in plastic containers which pro- vide one complete tank charge. Agent storage life expectancy is twelve years. The distributor must record the batch numbers and date of shipment receipt to be filed with each installation record. "ANSULEX" LOW pH LIQUID FIRE SUPPRESSANT 1.5 GAlLON SHIPPING WT.19 LB.

This regulated release assembly is used in single, double, and multiple-tank systems and must be mounted to a rigid surface. The release mechanism can be used to interconnect both the actuation and expellant gas lines as required per system design. The regulator is designed to allow a constant flow of gas into the tank at 110 psi (759 kpa) when the system is actuated. The agent tank must be ordered separately. In single, double, and multiple-tank systems, the provided expel- lant gas hose connects the agent tank to the bottom outlet of the regulator. In double and multiple-tank system configurations, the back outlet of the regulator is used as an expellant gas feed for one additional tank-enclosure or tank-bracket hookup. The enclo- sure contains the required knockouts to facilitate this connection. If a pressure switch is to be attached to the regulator, additional fit- tings are required. .. The tank is mounted within the enclosure. The tank cOntains an adaptor/tube assembly with a burst disc union. The burst disc helps prevent siphoning of the agent up the pipe due to significant temperature fluctuations in the area where the tank is located. The tank is mild steel and, under normal conditions, requires hydrosta- tic testing every twelve years. The detection and additional equipment required per system design are connected to the release mechanism. The enclosure contains knockouts to facilitate detection and additional hookups. The system can be actuated automatically or manually. Automatic actuation occurs when a fusible link within the detection system separates in a fire condition. Manual actuation of the system o=urs when personnel pull on the remote manual pull station pull ring.

The solenoid is used to provide electrical actuation of the release mechanism. The electric switch is used to protect the solenoid by opening the circuit to the solenoid once the system is fired. Additional electrical switches can be added as required for auto- matic equipment and gas shut-off accessories, as well as initiating audible and visual alarms.
