Product Description

product description

pre-action systems are usally employed in areas that are at risk for serious water damage due to damaged sprinklers and/or piping.they operate faster than dry systems.
the pre-action system is a fire extinguishing system with the nozzles normally closed.the pipe network is usually not filled with water.
when a fire occurs,after the fire detector alarms ,the automatic control system controls the valve exhaust and water filling,and changes from a dry type to a wet type system.water sprayinh only started when the ignition point temperature reached the open and closed sprinkler.
the pre-action system has the characteristics of both a dry sprinkler system and a wet sprinkler system,and also overcomes the shortcomings of the dry sprinkler system's low fire control rate and the wet system's prone to water stains.
the system can increase the speed of fire extinguishing .it can also be used in places where pipes and sprinklers are easily damage, instead of wet systems.it ccan alsobe used in buildings with high safety requirements for sprinkler systems.
