Fire Sprinkler Systems detect heat, smoke, or both they activate and use water to extinguish or control flames and minimize the spread of a fire until fire fighters arrive. These systems are ideal for everyday applications and to reduce property damage caused by a fire. Common Types of Fire Sprinkler Systems and Applications:
Wet Pipe Sprinkler: Wet pipe sprinkler system is fixed fire protection using piping filled with pressurized water supplied from a dependable source. Heat sensitive automatic sprinklers spaced and located in accordance with recognized installation standards are used to detect a fire.
Dry Pipe Sprinkler: Dry Pipe Sprinkler System is a automatically operated sprinkler system. The system piping from the Dry Pipe Valve to the heat actuated sprinklers is filled with pressurized air or nitrogen.
Deluge Sprinkler: Deluge systems are used where there are typically fast growing and/or high risk hazards. These types of environments are best suited for the use of a deluge type sprinkler system or spray system. A deluge system consists of a fixed piping system, a automatic sprinkler control valve (deluge valve) and open-head sprinklers.
Pre-action Sprinkler: These systems require independent detection systems to be used in conjunction with closed pipe sprinkler systems. The detection system maybe hydraulic, pneumatic or electric, and maybe actuated by smoke, heat, optical detectors, or be manual actuation. Preaction systems are usually supervised with air pressure. The purpose of the supervision is to monitor the integrity of the system. If the sprinkler head is broken or fused, or the piping is network is broken, the pressure will be reduced in the piping and an alarm will sound.
Deluge fire sprinkler system is similar to a pre-action system except the sprinkler heads are open and the pipe is not pressurized with air. Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection system.
