A Pre-Action Sprinkler System is a system which employs automatic and closed-type sprinkler heads connected to a piping system that contains air or nitrogen rather than water and has a supplemental system of detection serving the same area of protection. These systems are similar to Dry Pipe Sprinkler Systems in that the water is prevented from entering the piping by a valve, a pre-action valve. When the detection system is activated by the heat or smoke detectors, an electric signal is sent to the releasing solenoid and the valve opens. The water then fills the pipe and is ready to flow through the sprinkler heads that are activated. These systems are typically used in applications where an accidental discharge of water would be catastrophic, such as computer servers, telecommunications equipment, and high voltage electrical components.
Properly designed, installed, and maintained systems is key to their proper operation. BFPE International can assist you with making the right choice of sprinkler system for your application. We appreciate the opportunity to design, install, service, and test & inspect your system.
