PROBLEM TO BE SOLVED: To easily stop an alarm while securing security by providing a dedicated card for stopping alarm output and stopping alarm output by passing the card through a card reader. ;SOLUTION: A controller 10 rings a buzzer 14 and reports to a security company when the output of an opening/closing detector 13 is turned to a door open state at the time of being in a locked state. The controller 10 stops the ringing of the buzzer 14 when a magnetic card 19 in which information for inhibiting the ringing of the buzzer 14 is recorded is read by the card reader 11 in the state of ringing the buzzer 14. In this case, when an operation of stopping the ringing of the buzzer 14 is performed once, even when the output of the opening/closing detector 13 is turned to the door open state in the locked state, the buzzer 14 is not rung by abnormality at all until the magnetic card 19 is read again. Thus, an unnecessary alarm over the long period of time is prevented.;COPYRIGHT: (C)1998,JPO
