A plurality of detection devices positioned at different designated positions can share the same communication bus, and different detection devices have different addresses and different numbers of different sensors, so as to partition.
The fire extinguishing device is started to extinguish the fire after the alarm is delayed for a preset time, so that workers have time to confirm whether false alarm occurs or not, and the starting of the fire extinguishing device to be started is stopped after the false alarm occurs, thereby avoiding unnecessary loss, and meanwhile, even if the fire occurs really, the fire extinguishing device can reserve a certain time for the workers to evacuate and evacuate the site. The preset time period may be 30 seconds.
Optionally, the main control system is further configured to control a power control switch (such as a circuit breaker) to cut off a working power supply of the device body when the fire detection information represents a fire, so as to avoid causing a greater potential safety hazard.
