Smartair L3 escutcheon
This lock offers exactly the same function as the L2 lock with the exception that the L3 offers a key override cylinder function on the internal and external side.
This lock can be used with a variety of mortice lock cases and different styles of cylinder combination. For example, you may use the lock with a sashlock case that will enable card access during working hours but you have the ability to mechanically deadlock the door and effectively block off the lock. This gives both security and convenience.
The internal plate could have a key cylinder for locking from within or a thumbturn for manual unlocking of a deadbolt.
A useful variation of this lock is the "deadbolt projection" model where the external lever can be lifted up or pushed down on activation. This enables the lock to be used in some multi point lock applications on PVC or wooden doors.
When ordering, the distance between the centre of the lever handle and the centre of the keyhole are important. Lock-tec usually use the lock with a 72mm DIN standard lock case but other sizes are available.
The unit is available as an internal or external escutcheon and in a variety of finishes.
