The ZSFZ system is a general-purpose fixed fire extinguishing system, consisting of wet alarm valves, delay devices, hydraulic bells, and other components such as pressure switches, flow indicators, and nozzles. The system remains in standby mode, with the pipeline filled with pressure. When a fire occurs at any point within the protected area, the ambient temperature rises, causing the temperature-sensitive elements (glass bulbs) on the nozzles to activate. The sealed components disengage, automatically initiating the system to spray water directly onto the fire area and emit an alarm signal to achieve the purposes of alerting, extinguishing, and controlling the fire.
The system is suitable for buildings that can be extinguished by water, commonly installed in production sites, warehouses, hotels, shopping malls, hospitals, theaters, office buildings, high-rise structures, and garages, etc., where fire hazards are present.
