Self-locking, with night function

Self-locking multi-point locking system with integrated latch blocking, control of the locking mechanism, and night function. Suitable for use in entrance doors of houses and apartments as well as in commercial buildings. When the night function (NF) is intentionally activated via the cylinder, the interior handle is blocked. Exiting is only possible through the switch function. This means, for example, that children cannot leave the house without identification. At the same time, burglary protection is increased by preventing manipulation of the interior handle from the outside. Operation from the outside is done via the cylinder.

To activate the night function (NF): Turn the key in the locking direction until it stops.
To deactivate the night function (NF): Turn the key in the opening direction until it stops.

The cylinder screw is not centered on the profile. To determine the cylinder lengths: Center of the profile = center of the lock cylinder. No asymmetrical cylinders with L-cams are permitted. No reduction sleeves for the lock nut/spindle are permitted. No external mechanical bolt switch contacts are recommended.
