Self-locking, with night function

Self-locking multi-point locking system with integrated latch blocking, control of the closing sequence, 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 change function. This prevents, for example, children from leaving the house without identification means. At the same time, burglary protection is enhanced 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 to the stop.
To deactivate the night function (NF): Turn the key in the opening direction to the stop.

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