ABSTRACT:
An electrically operated locking system for doors and the like has an electrically operated locking device installed inside the door. A control device installed outside the door is operatively connected with the locking device. A sensor detects the position of the door with respect to the door mounting by a light activated means electrically coupled to the locking device such that when darkness is sensed, the locking device is activatable to operate the locking unit. When light is sensed, however, the locking device is nonactivatable.
