In a fire-fighting system (sprinkler, hydrant, fire pump circuit), it use as a pressure monitoring/control switch to ensure proper pump operation and pipeline integrity.
| Fire Pump Start/Stop Control | ● The pressure switch detects a drop in system pressure when a sprinkler head opens or a fire hydrant valve is used | |||||||||||||||||
| ● It will sends an electrical signal to the fire pump controller to start the pump automatically | ||||||||||||||||||
| ● When the pressure returns to the preset level, it may stop the pump (for automatic systems) | ||||||||||||||||||
| Pressure Supervision/Alarm Function | ● The switch provides a low or high pressure alarm signal to the fire alarm control panel | |||||||||||||||||
| ● This ensures the system is always in a ready-to-operate condition, and alerts operators to any abnormal conditions (like pump failure, leakage, or blocked line) | ||||||||||||||||||
| System Safety Protection | ● Prevents overpressure damage to the system by cutting off the pump circuit if the pressure exceeds the safe limit. | |||||||||||||||||
| ● Ensures safe operation of pumps, valves, and pipelines under varying load conditions | ||||||||||||||||||
