DIN preset for left, convertible to right. Panic function B, selectable to open inwards or outwards. These self-locking multipoint locks have a door handle, panic door fitting, or push bar installed on the inside of the door. There is also a door handle on the outside of the door. In the unlocked state, the door can be opened from both sides. In the locked state, the door cannot be opened from the outside, but can always be opened from the inside via the door handle, panic door fitting, or push bar (panic function selectable to open), retracting the main bolt and the two locking bolts. When the door closes, the lock automatically engages (self-locking). The square (nut) is split in panic function B. This panic function is suitable for doors that may need to be opened from the outside temporarily (day operation). Day operation can be activated via the cylinder by turning the key in the opening direction until it hits the stop, then the door handle on the outside is engaged. Suitable for entrance and apartment entrance doors, security, escape route, and fire protection doors.
