ABSTRACT:
A modular lock unit has a lock solenoid and an unlock solenoid connected to opposite ends of a bolt cam slide for operating a horizontally reciprocal bolt. A centered circuit automatically locks the door when it is closed and automatically retracts the bolt in the event that any obstruction is provided in the strike in the door so as to preclude damage to the solenoid employed for extending the bolt. A time delay relay in the circuit terminates power to the lock solenoid after it has been actuated for 1.5 seconds so as to preclude solenoid damage if the bolt is blocked.
