ABSTRACT:
The invention is an automatic door locking system that provides for unlocking of the door to a room from a remote location. In detail, the system includes a door lock that is manually operable by a lever mounted on the room side of the door when the door is locked. An electrical circuit is provided for unlocking the door lock from the remote location such that door can be opened from the opposite side of the door and to reset the door lock to the locked position when the door is closed upon the door being opened. In addition, the electrical circuitry provides visual indication of the status of the door at the remote location.
