4L79 - Electromechanical Slam Action Cell Lock Application PurposeTo provide secure locking of swinging cell doors using third party access control systems or conventional key control where automatic deadlocking is a requirement.OverviewThe 4L79 is a surface mounted lock of robust construction based on the Chubb Locks Custodial Services standard cell lock footprint. The main bolt is automatically extended providing a throw of 32mm and deadlocked on closure of door.Electrical Mode - Deadlocking is achieved when the door is closed and the bolt fully extended, no electric input is required to lock. Unlocking by 24 Volt DC from an external source to energise (lift) the locking solenoid and withdrawing the bolt via the handle. The bolt remains retracted when fully withdrawn and out of frame. Solenoid is designed to be momentarily energised to facilitate un-locking.Mechanical Locking - Locking achieved using conventional (mechanical key) to engage a secondary deadlock when the door is in frame and main bolt is fully extended. Electric unlocking cannot be achieved while the mechanical locking mechanism is engaged.Manual Override - In the event of power or communication failure an override key is used to lift (override) the electric locking unit. Both keys are supplied to a different combination and are clearly identified.
