A power control system using a manless alarm system and a controlling method thereof are provided to minimize the waste of a standby power at night by automatically controlling the supply of the commercial AC power according to an operation signal of the manless alarm system. A relay(10) is operated by connecting a manless alarm system(200). A magnetic switch(20) controls the supply of the commercial AC power controlled by the relay. A plurality of lamps indicate the supply state of the commercial AC power. The relay switches the connection between internal contact points by being excited or degaussed by applying or blocking the current to an internal electromagnetic coil through a power terminal(11). |
