18991 MINT SV NF

Multipoint lock, self-locking, night time mode

Product profile

For use in house and apartment entrance doors and in commercial buildings. Exiting using the inside lever handle is possible at all times when night function is not activated. When night function (NF) is deliberately switched on via the cylinder, the inside lever handle is blocked. It is only possible to exit using the latch withdrawal function. This means, for example, that children cannot leave the house without using the identification media. Increased break-in protection is provided at the same time as the inside lever handle cannot be tampered with from outside. Operation from outside is via the cylinder/latch withdrawal (knob/pull handle).

To switch night function (NF) on (or off): Turn the key in the locking direction (or unlocking direction) until it stops.
