automatic: when any detector in the protection area gives an alarm, a fire alarm signal is transmitted to the acousto-optic alarm in the protection area of the fire alarm control panel to act, and all people in the protection area are evacuated and evacuated immediately. When two detectors in one protection area alarm at the same time (or one detector is triggered by a manual alarm button), an audible and visual alarm outside the protection area acts, and a fire alarm controller sends out a linkage signal to link equipment such as a fan, a fire valve and an air conditioner; the fire alarm control panel automatically delays for 30 seconds according to the preset time through the fire extinguishing operation panel. After the delay time is over, the fire alarm control panel sends out a fire extinguishing agent releasing signal, the electromagnetic valve on the driving gas cylinder group is started, the selection valve of the corresponding protection area is opened through the driving gas, then the container valve on the fire extinguishing agent cylinder group is opened, the fire extinguishing agent is released to the collecting pipe through the pressure reducing valve, the flavor enhancer device on the collecting pipe explodes to release flavor enhancer, the fire extinguishing agent mixed with the flavor enhancer flows to the selection valve, and then the pneumatic acousto-optic alarm device (optional) acts under the pressure of the fire extinguishing agent to send out acousto-optic alarm; the fire extinguishing agent mixed with the odorant flows to the selection valve, the pressure switch acts, the pressure transmitter (optional) feeds back a pressure signal to the fire alarm controller in real time, and the control panel turns on the gas spraying indicator lamp after receiving a gas release signal fed back by the pressure switch on the main pipeline or the pressure transmitter to warn people outside the protection area not to enter the protection area. The fire extinguishing agent is sprayed in the corresponding protection area to realize physical or chemical fire extinguishing or inerting.

Manual operation: the system can start the follow-up automatic spraying fire extinguishing program by manually triggering a manual starting button on the fire alarm control panel or an emergency starting button on the manual operation box.

Mechanical emergency: in case of emergency, the safety pin of the driving gas cylinder group is taken out, the manual actuating mechanism of the container valve of the driving gas cylinder group is manually pressed down to drive the gas cylinder group to act, the selector valve and the fire extinguishing agent cylinder group are started, and the subsequent automatic spraying fire extinguishing program is executed.
