Series 92/35 self-locking locks, with panic mode, are typically installed in wooden doors with high security. When the doors are closed, the lock is always engaged. To open the door from the outside, you need a key or electric impulse from a connected 2N IP intercom or reader, which ensures the door handle is fully functional. If such an impulse is not sent to the lock, the door handle is movable, but the door cannot be opened.
