Abstract: A remote control station and integrally installed electronic control circuit for use with a bolt and lock mechanism is set forth. In the lock, an air supply connected with first and second solenoid valves is incorporated and has a rod which extends to manipulate the bolt; bolt position is indicated by a switch means determining movement of the bolt to the deadlock position, and a door position switch is also incorporated. Various control signals are formed and are interlocked so that remote control or key switch control of the lock mechanism is obtained. It is implemented by providing control signals to the solenoid valves. They cause the bolt to move between the deadbolt and retracted positions, or to the intermediate slamlock position.
