ABSTRACT:
An improved door locking and monitoring assembly is provided which is power activated. The assembly comprises a housing disposable in a door frame and defining a passageway which has a bolt slidably disposed therein and lockset means in the door member. A lever is pivoted in the housing. The lever is L-shaped, with a spring biased vertical arm below it. The rear of the latter is urgeable upwardly by a ball to pivot the lever and move the bolt forward into the locked position. The ball is urgeable upwardly by a solenoid actuated plunger. The biased L-shaped arm has the arms thereof pivoted allowing relative angular movement. An extension on one of the arms is forced into an opening in the housing when the bolt is fully extended to lock-set the bolt. When the bolt moves into the locked position, a member on its rear end closes a powered switch to signal this condition. The assembly also can include a door position indicator device connected to or disposed within the housing and containing a switch normally closed by the door when in a closed position and which can provide a signal indicating the position of the door. The assembly assures full monitoring of a door fitted with the assembly so that it is known remotely whether the door is locked, unlocked, or dead-locked, and when the door is opened.
