This electromechanical security mortise lock is a self-locking escape route lock with split follower and controllable outside handle. DIN EN 179 escape route standard.

Tubular frame models with 35 mm backset for narrow profiles and doors.
Self locking is triggered by an auxiliary control latch when closing the door, when it is pushed automatic deadlocking occurs. The function of the control latch is connected to the position of the latch bolt so that the locking mechanism is engaged only when both latches are operated. Avoiding accidental and manipulative locking can thus be avoided.

Control is always done by DC. The coil is capable of continuous duty (100%).

Fail locked models. Unlocks under voltage, locked without it.
