Product Description
Working Principle
The ZSFZ system is a commonly used fixed fire extinguishing system consisting of a wet alarm valve, delay device, hydraulic alarm bell, pressure switch, and water flow indicator. The pipeline network is kept in a standby state, filled with pressurized water.
When a fire occurs, the ambient temperature rises, causing the heat-sensitive glass bulb on the sprinkler nozzle to burst. This releases the sealing component, causing the system to automatically start. It directly sprays water onto the fire area while simultaneously sending an alarm signal to control the situation.
Applications
This system is suitable for buildings where water can be used as an extinguishing agent and the ambient temperature stays above freezing (4°C). Common installation sites include:
- Production Factories & Warehouses
- Hotels & Shopping Malls
- Hospitals & Theaters
- High-rise Office Buildings & Garages
