摘要： A locking and unlocking mechanism to secure a hinged door has three control positions of the controlling mechanism. In the electrical control condition the door may be opened either by an operator at a remote position or individually from within the closed room or from the outside of the closed room. The hinged door is spring loaded so that when the control mechanism is in either electrical or release control position the door may be biased open. A deadlock control position insures that the opening mechanism is prevented from moving so as to secure the door in the locked position. Direct operational links connect the control mechanism with the securing mechanism.

摘要： A security system includes combination electrical and mechanical unlocking and locking mechanisms. The electrical and mechanical mechanisms are independent of each other. The electrical mechanism is the primary system for opening, closing and locking a plurality of doors such as cell doors and the mechanical system is backup in case of electrical power failure.
