Pre Action System
The Single Interlock with Wet Pilot Actuation and Double Interlock Pre action System with Electric/ Pneumatic Release is generally used to protect water sensitive areas such as computer rooms, storage areas of valuable articles, to avoid water damage due to damaged sprinklers or damaged sprinkler piping.
Preaction System is also effectively used to have Pre-alarm of a possible fire condition and allows time to extinguish fire by hand held fire extinguishing equipment, prior to water discharge through sprinkler heads. It uses an automatic sprinkler with supplemental detection system. In the event when fire cannot be extinguished by hand held fire extinguishing equipment, the increase in temperature will open one or more sprinkler heads to discharge water.
