Purpose

To provide secure locking of swinging cell doors, under conventional key control. Additional “privacy” locking mechanism to provide a level of privacy and security for the cell occupant, the privacy function can always be overridden by the staff key. The lock can be configured to provide a softer aesthetic appearance without reducing security.

Overview

Secure locking is achieved as follows:

Staff Key
Locking/unlocking is achieved by a full turn of the key allowing the handle to throw or withdraw the bolt. When the key is withdrawn the main bolt can be left in two positions fully thrown (i.e secure when door in frame) or bolt fully withdrawn and locked back. Withdrawal of the main bolt will automatically withdraw the prisoner’s 'privacy' bolt if thrown.

Privacy Key
The 'Privacy' bolt can be locked/unlocked from outside by a pin tumbler cylinder or from inside by a cylindrical knob.
Note: Locks can be prepared to accept customer’s choice of cylinder, details of which need to be supplied prior to ordering.
