After initialization is completed, the sensor enters a circulating detection state, so that when a fire detection early warning system detects fire hidden danger, a red indicator lamp on a fire extinguishing starting alarm switch in a driving area flickers, and meanwhile, an alarm sends out a rapid alarm signal. When the early fire condition develops to the temperature abnormity in the fire reaches the set temperature value, the red indicator lamp on the fire extinguishing starting alarm switch positioned in the driving area is normally on, the alarm sends out an emergency long-sounding alarm signal, and meanwhile, the fire extinguishing device is automatically started to extinguish the fire. When a fault of a connecting circuit occurs, a red indicator lamp on a fire extinguishing starting alarm switch in the driving area flickers, and meanwhile, an alarm sends an intermittent alarm signal. When the fire extinguishing device has a fire extinguishing agent leakage fault, a red indicator lamp on a fire extinguishing starting alarm switch in a driving area flickers, and meanwhile, an alarm sends an intermittent alarm signal. When the starting is successful to send the feedback signal, the red indicator light and the yellow indicator light are on all the time, and the alarm sends out an emergency prolonged alarm signal. If the fire extinguishing starting alarm switch works normally, a green indicator lamp on the fire extinguishing starting alarm switch in the driving area is normally on, and a yellow indicator lamp flashes intermittently for a long time.
