PRODUCT OVERVIEW
The pre action device combines automatic fire detection and alarm technology with automatic sprinkler fire extinguishing sys-tem,providing dual protection for the protected object. It is par-ticularly suitable for important places that are cold, frozen, and usually avoid water stains and do not allow accidental spraying,such as computer rooms,generator rooms, data rooms,historical archives,elevated warehouses,etc.The pre action device consists of an alarm valve group, a con-trol panel, an air pressure maintenance device,and an air supply device. It is a one-way valve group device that can be opened by electric, pneumatic, mechanical, or other methods to allow water to flow into the water spraying system in one direction while giv-ing an alarm. When there is no fire,the side pipeline of the system is filled with compressed air, so the system has the characteristics of a dry system and can meet the needs of automatic water spraying under high temperature and cold conditions.
