Overview

The 3F51 is a mortice lock of robust construction. 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.
