Abstract
A powersaving room security system including a switch connected to a door locking system which generates a lock signal congruous to proper locking of the door. A central control unit produces control signals which can be transmitted through the room AC lines. The control signal corresponds to the existence of the lock signal. Module units are respectively connected to each of the various electrical wall switches and receptacles in the room and respond to the control signals for correspondingly controlling the respective receptacles and wall switches. In this way, lights and appliances in the room can only be permanently energized from the room AC lines when the door of the room is properly locked. At the same time, the system provides an energy saving system by turning off all appliances and lights which the guests may have left on without leaving the room.
