A relay RP for power failure detection is connected between both ends of the capacitor C, and is in an energized state when the commercial power supply V is normal. The receiver circuit is supplied with 24V power through the circuit (common power supply circuit). In the event of a commercial power outage, the power outage detection relay RP
