When the voltage rises, the resistance value of the detection end AB is reduced, so that the voltage of the second pin of the detection chip IC is reduced. When the voltage is higher, the second pin and the fourth pin of the detection chip IC are changed into low level, the tenth pin and the twelfth pin output low level, so that the first light-emitting diode V2 and the third light-emitting diode V3 are lightened, the third diode D3 is conducted with the triode VT, and the alarm B gives out alarm sound.
