Component Description CHAPTER 2 COMPONENT DESCRIPTION The Range Guard Wet Chemical Fire Suppression System consists of the following major components: • Suppression — Agent storage cylinders distribution piping. nozzles, and detection devices finechanlcal and electrical) • Controls • Auxiliary Components Cylinder and Valve Assembly The Wet Chemical Fire Suppression System utilizes live sizes of cylinders. The cylinders consist of a factory -filled wet chemical agent and valve assembly. The cylinders conform to DOT/fC specification 4BW/4BA and NFPA standards. Distribution Piping The distribution piping (not supplied by Badger Fire Protection) is designed to distribute the wet chemical agent to the hazard areas. In the Range Guard pre-engineered system, pipe sizes, minimum and maximum pipe lengths and number of pipe fittings are predetermined. See Chapter 3 for more details. Nozzles There are seven types of nozzles for the Wet Chemical Fire Suppression System. Each type of nozzle has been designed and tested for specific applications and areas of coverage. The nozzles are: • ADP R • LPF • LPR • GRW • F • DM Detection Devices There are two methods of detection that can be employed in the system: mechanical or electrical. Mechanical detection uses fusible -link or thermo-bulb link detectors to provide reliable performance. The detectors are designed to separate at a specific temperature and release tension on the detection cable which causes the release mechanism to activate. Fusible -link detectors are available in four temperature ratings, and the thermo-bulb detectors are available in six temperature ratings. Electrical detection uses heat detectors that are equipped with self -restoring, normally -open contacts which close when a predetermined temperature is reached. Heat detectors are available In six set points. PM 609127100.000 2.1 Apr11 2009
