3G222 Mk2

Purpose

To provide secure deadlocking of swinging doors or gates where a superior level of security is necessary. This lock is specifically designed for very high use applications; typically securing perimeter doors and main access routes.

The 3G222 magnetic lock affords a higher level of security due to the inability to sight read keys. The magnetic key code is impossible to read or duplicate using normal human senses alone or duplicate with standard workshop equipment.

Overview

The 3G222 Mark 2 is a mortice deadlock of robust construction based on the Chubb Locks Custodial Services small mortice footprint.
The mechanical deadbolt provides an overall throw of 40mm which comprises an initial throw of 20mm and a second throw of a further 20mm.

The lock provides two independent bolt throws where each throw is operated by a unique key. The keys are designed so that neither key will perform the function of the other key.

The lock is operable from both sides with separate key holes for each key type. The escutcheon is designed to prevent the wrong key being inserted into the lock.

Secure locking is achieved as follows:

Servant Key – Operates first throw only.
Locking is achieved by inserting the servant key into the upper keyhole and turning the key through 90º in an anti-clockwise direction. The bolt is then extended to the first position by turning the handle.

Unlocking
is achieved by inserting the servant key into the upper keyhole and turning through 90º in an anti-clockwise direction. The bolt is then withdrawn by turning the handle.

Note: the Servant key will not operate the second (master) throw.

Master Key – Operates second throw only.
Locking is achieved by inserting the master key into the lower keyhole and turning the key through 90º in an anti-clockwise direction. The bolt is then extended to the second position by turning the handle.

Unlocking is achieved by inserting the master key into the lower keyhole and turning the key through 90º in an anti-clockwise direction. The bolt is then withdrawn by turning the handle to enable operation under the servant key.

Note: The master key will not operate the first (servant) throw.
