2. Working Principle
When the control mode selection key on the automatic fire alarm and fire extinguishing controller is set to the "auto" position, the fire extinguishing system is under automatic control. When a fire occurs in the protection area, the temperature and smoke detectors will send out a fire signal through the automatic fire alarm and extinguishing control After the logic analysis of the device, it sends out a combined sound and light alarm signal, and sends out a linkage command at the same time to close the linkage device. After a delay, a fire extinguishing command is issued, the starting valve is opened to release the starting gas, and the starting gas is opened through the control gas pipeline valves and container valves release the fire extinguishing agent and implement fire extinguishing.
