Under normal conditions, the control mode of the fire alarm controller is selected in the "automatic" position, and the fire extinguishing device is in the automatic control state. When a fire occurs in the protected area, the fire detector sends a fire alarm signal, and the fire alarm controller sends an audible and visual alarm signal, and at the same time sends a linkage command to shut down ventilation equipment such as air conditioners, fans, and fireproof roller shutters. After a delay of 0~30 seconds (people in the protected area must evacuate quickly at this time), the DC24V/1.5A fire extinguishing signal is output to drive the starter electromagnetic to open the container valve on the fire extinguishing agent storage bottle, and release HFC-227ea to extinguish the fire.

2) Manual control

When someone is working or on duty in the protected area, the control mode of the fire alarm controller is selected in the "manual" position, and the fire extinguishing device is in the manual control state. If a fire occurs in a protected area, press the "start" button on the fire alarm controller to start the fire extinguishing device according to the "automatic" program to extinguish the fire. You can also press the "emergency start" button set at the door of the area after confirming that all personnel have evacuated, and the delay will be 0-30 seconds to release HFC-227ea to extinguish the fire. When a fire alarm occurs, if it is found that there is no need to activate the fire extinguishing device to extinguish the fire within the delay time, the "Emergency Stop" button on the fire alarm controller or outside the protection area door can be pressed to terminate the fire extinguishing procedure.
