Electro-mechanical Cell Lock

Purpose
To provide secure locking of swinging cell doors using third party security management systems (SMS) or conventional key control.

Overview
The 4L78 is a surface mounted lock of robust construction based on the standard cell lock footprint.
The main bolt is a sprung latch providing a throw of 25mm, secure locking is achieved by two independent methods:

Electrical Mode. Locking/unlocking by 24 Volt DC controlled sequence from an external source (SMS). Bolt withdrawal by handle, which should also be used when closing the door.

Manual Mode. Locking/unlocking achieved using conventional (mechanical key). Bolt withdrawal by handle, which should also be used when closing the door. Key operates from corridor side only.

Manual Override. In the event of power or communication failure an override key is used to disable electric locking function. The lock will operate if slammed to shut, however, we recommend that in normal operation the handle is used to withdraw the bolt when closing.
