Self-locking

The security lock 309N has a mechanical automatic locking function. In the
case of door locks with automatic locking, the closed door is always locked.

Functional principle

When the door is closed, the latch bolt (Fig. 4 –
plate is pushed inwards. If the latch bolt is pushed in, then the control latch
(Fig. 4 – 1 ) can also be pushed in. If the door is completely closed, the latch
bolt slides into the latch opening in the locking plate and is thus extended
again, while the control latch remains pushed-in.
If the latch bolt is extended while the control latch is pushed in, the dead-
bolt (Fig. 4 – 3 ) is released and extended by means of a spring mechanism.
This sequence control system prevents the deadbolt from extending when
the door is opened during normal use.

Profile cylinder (locking cylinder)

The function of the profile cylinder differs depending on the lock version
("Release", page 43).
The lock is unlocked via the profile cylinder (locking cylinder); the door
handle(s) is (are) engaged and disengaged. The locking with the locking
cylinder is not necessary, nor is it possible. The locking cylinder has an
internal stop collar which prevents it from turning completely.
The key must be pulled out in normal operation.
