What is the role of the fire engine pressure switch?
The input module, which is called a monitoring module, is used to detect the working status of the equipment. It is usually monitored to use the normally open signal device. Once the device is being monitored and normally closed, the alarm information of the device action is sent to the host.
?? Pressure switch: When the alarm valve action, alarm pipe water, tube pressure is greater than the set value, the switch action, to the system feedback alarm valve work.
?? Signal valve: In order to avoid misuse of personnel, resulting in the valve closed, the system can not work, so the valve installed on the signal feedback device to avoid misuse
The pressure switch is the main part of the fire sprinkler system and is installed in the wet alarm valve of the fire sprinkler system.
The role of fire pressure switch is when the fire sprinkler pipe pressure is less than the water supply side of the pressure, the pressure switch will automatically move, and the action signal feedback back to the fire alarm system on the host. Control the host to receive the signal to start the fire spray pump to pressurize.
