A restraining bar is pivotally mounted to slide on a support affixed to the inner surface of a door. In its locked position, it is under a restraining means affixed to the door'"'"'s latch-frame casement. A switch is situated between the restraining bar and the support so that movement of the door when the restraining bar is in its locked position will cause the restraining bar to pivot toward the support and thereby close the switch to actuate an alarm.
