Heavy Duty Morticed Electro-mechanical Cell Lock
To provide secure locking of swinging cell doors using third party security management systems (SMS) or conventional key control. The lock can be configured to
provide a softer aesthetic appearance without reducing security.
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 with drawl by handle, which should also be used when closing
Manual Mode: Locking/unlocking achieved using conventional (mechanical) key.
Bolt with drawl 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.
