Wet Pipe Sprinklers Wet Pipe sprinklers are the most common type of fire sprinkler systems and the most reliable, with the only operating components being the automatic sprinklers and, in some instances, the automatic alarm check valve. An automatic water supply provides water under pressure to the system piping and all the piping is filled with water. When an automatic sprinkler is exposed to sufficient heat, the heat-sensitive element (glass bulb or fusible link) releases water from that sprinkler. Wet pipe sprinklers react to a specific range of temperatures.","Dry Pipe Systems Dry Pipe systems are used only in spaces in which the ambient temperature may be cold enough to freeze the water in a wet pipe system, such as unheated buildings, parking garages, outside canopies attached to heated buildings and refrigerated coolers. Dry pipe systems are the second most common fire sprinkler. Disadvantages include increased complexity, higher installation and maintenance costs, increased fire response time and increased corrosion.","Deluge Systems Deluge systems are systems that have open sprinklers – the heat-sensing operating element is removed or specifically designed to be open so that all sprinklers connected to the water piping system are open. Deluge systems are used for special hazards where rapid fire spread is a concern, as they provide a simultaneous application of water over the entire hazard, and are commonly seen as preventive measures to prevent egress of fire from an external source, such as high-rise windows, warehouse bay entries and openings in a fire-rated wall. Water is not present in the piping until the system operates.","Pre-Action Systems Pre-Action systems are hybrids of wet, dry and deluge systems, depending on requirements. There are two main sub-types of pre-action systems: single interlock and double interlock. Single interlock systems are similar to dry systems except that they require a preceding fire detection event, typically the activation of a heat or smoke detector. Double interlock systems are similar to deluge systems except that automatic sprinklers are used. Pre-action sprinkler systems are commonly used in museums with rare works or art, manuscripts or books, and data centers.
The Pyott-Boone Electronics’ Flow Boss Sprinkler System provides protection for conveyor belt drives, storage and take-up areas, and bearings and hydraulic boxes against costly and damaging conveyor fires. Building upon our already proven fire suppression systems, we have redesigned several features for increased and enhanced protection. Offering multiple steel structure sizes that easily accommodate diverse roof heights; this product is flexible for all mining operations and innovative engineering ensures long lasting use of the system. Packaged systems are available for 50ft of coverage, ModelFB-50, or 75 ft, Model FB-75 but can be custom ordered for any coverage length.","The sprinkler bar has been designed to attach to the belt structure using two, heavy duty oval eye nuts to minimize the tools needed for installation. Two sprinkler heads provide thorough coverage of two belts, keeping safety the number one priority. FM approved and UL listed components are integrated into the fire deluge system to provide the best coverage available on the market today. A pressure test manifold is included to ensure proper operation by providing eight spray nozzles for testing the flow rate of the system along with a pressure gauge for verification that the system is operating above the minimum 10psi as specified in NFPA 120 Chapter 4.3.3.5.2.","PBE offers installation, technical assistance and training to guarantee each product is correctly configured and properly maintained.
