3L215

Purpose

Latchbolt to provide electric lock / unlock of swinging cell doors. Lock is designed to accept an input signal from a third party access control system to energise and disengage the locking solenoid. The lock is fitted with a 5 lever anti-pick mechanism with a factory restricted key profile. The key is supplied to enable an override for the electric locking if power fails.

It is not anticipated that the override key will be used on a regular basis and the locking unit is tested to 60,000 key operations.

Overview

The 3L215 is a mortice lock of robust construction. The main bolt is automatically extended providing a throw of 25mm and electrically deadlocked when the main bolt is fully extended. The main bolt cannot be electrically locked back when fully withdrawn.

Electrical Mode: Deadlocking is achieved when the bolt is fully extended, and the solenoid locking bolt is engaged.

Unlocking by 24 Volt DC from an external source to energise (lift) the locking solenoid and withdrawing the bolt via the handle.

Solenoid is designed to be continuously energised to facilitate and maintain unlocking.

Mechanical Locking - Not available

Manual Override: In the event of power or communication failure an override key is used to lift (override) the electric locking unit.
