[0061] Referring to Figure 2 , when the rectifier module is electrified, the first coil is in an electrified state, and at this time, the switch is in a disconnected state, when the AC power supply fails, the rectifier module stops supplying power, at this time, the first relay acts, the switch is in a closed state, the 2nd and 4th terminals are respectively connected with one end of the standby DC power supply, and the 3rd and 6th terminals are respectively connected with the other end of the standby DC power supply.

[0062] In this example, the early warning display module is connected with the 2nd and 3rd terminals respectively, and the siren module is connected with the 4th and 6th terminals respectively, when the rectifier module stops power supply, the 2nd and 3rd terminals are connected with the standby DC power supply respectively, the early warning display module works, and meanwhile, the 4th and 6th terminals are connected with two ends of the standby DC power supply respectively, the siren module works.

[0063] In this example, the 2nd and 3rd terminals are regarded as a group of terminals corresponding to another group of terminals, and the 4th and 6th terminals are regarded as the aforementioned group of terminals.

[0067] Specifically, the group of terminals in the at least one group of first terminals specifically refers to the terminals connected with the siren module in the at least one group of terminals, when the group of terminals stops power supply, the siren module stops working.

[0068] In this way, the siren module can be reset, and the siren alarm can be manually eliminated.

[0069] Specifically, in the embodiments provided by the utility model, the control end of the second relay is a second coil, the controlled end is a single-pole double-throw switch, when the single-pole double-throw switch is in the first state, a group of terminals in the at least one group of first terminals are powered on,
