Reliable Wet Alarm Valve Ensuring Safety in Plumbing

  Product Overview The ZS7 system is a general-purpose, high-efficiency fire extinguishing system. It consists of a wet alarm valve, a retarder, a hydraulic alarm bell, and other components (such as pressure switches, water flow indicators, and sprinklers). The system remains in a standby state with the pipe network pressurized. When a fire occurs in the protected area, the ambient temperature rises, activating the temperature-sensitive element (glass bulb) on the sprinkler head. The sealing component then automatically detaches, automatically activating the system and spraying water directly onto the fire area.  An alarm signal is also triggered to achieve the purposes of fire alarm, fire extinguishing, and fire control. It is suitable for buildings where water can be used for fire extinguishing and is typically installed in areas with fire hazards, such as product facilities, warehouses, hotels, shopping malls, hospitals, theaters, office buildings, high-rise buildings, and garages.
