When detecting combustible gas, there will be several combustible gas alarms at several nodes, which consumes a lot of material resources; when combustible gas leaks, the prompt light will light up but people cannot see it from a distance, and the alarm light will sound and flash to prompt workers to check in time; multiple connection ports are provided to improve work efficiency and reduce material consumption; however, the device still has the following defects:
