Abstract
PURPOSE: To connect two plugs to any input terminals by arranging in such a way that when the power is supplied to the two sets of input terminals, the power supply circuit for the alarm unit is shut off and when the power is not supplied to one of them, the power supply circuit is closed.
CONSTITUTION: Alarm units such as buzzer 13, indication lamp 14, etc. connected to the power supply circuit of power failure alarm unit 10 are provided for two sets of power input plug receptacle 6 and terminals of A/C power supply 31. When the power is supplied to both of the two sets of input terminals, the power supply circuit for buzzer 13, etc. is shut off and when the power is not supplied to either one of them, the power supply circuit is closed to energize buzzer 13. With this invention, the power failure alarm can be energized by connecting two plugs of unit 10 to either one of the input terminals.
