Tamper-resistant locking and notification system for detention cells
A locking system that has an opening in a door adapted and arranged for receiving a lock bolt and a lock fixed in a wall for actuating a lock bolt adapting and arranged for being received by the opening in the door when the door is closed. Alternatively, the locking system is mounted on the exterior of the detention cell door and the adjacent exterior cell wall. The locking system further comprises a blocking strip protruding from a doorjamb, the strip coupled to the door jamb, the strip coupled to the door jamb and positioned adjacent the lock bolt for blocking access to the lock bolt between the door and the doorjamb. The locking system further comprises a system for monitoring and reporting the status of a detention cell door, the lock bolt, and the roller bolt.
