Heavy Duty Morticed Latch

Purpose
The 3R47 was introduced, at the request of the Home Office Prison Department, with the original intention of providing secure locking of cell doors in Crown and Magistrates Courts, by means of a lock that is essentially different to those used in UK prisons.

Overview
The latchbolt provides an overall throw of 20mm. The lock offers a number of keying and handle configurations to suit a variety of operational requirements and is fitted with an external visual indicator.

Single Locking Action
Keyed to pass or to differ. Locking is achieved by inserting the key into the keyhole and rotating fully. This action will both deadlock the latchbolt and lock the handle in position. Unlocking is achieved by inserting a key into the keyhole and rotating fully. This action will release the latchbolt and unlock the handle. The latchbolt is then withdrawn using the handle.

Double locking action
Servant Key Operates single locking action only Locking / Unlocking as above.
Note: the Servant key will not operate the double (master) locking action.
Master Key Operates double locking action.
Locking - providing the servant key has been used to operate the first locking action, the master key can be utilised. By inserting the master key into the keyhole and rotating fully over-locking will be achieved. The servant key will be disabled and unauthorised use of the servant key will be prevented.

Unlocking is achieved by inserting the master key into the keyhole and rotating fully, this action will remove the over-locking enabling operation of the servant key.

Note- The lock can be configured to operate the double locking action only or if required to operate both single and double locking actions from a single key.
