These multi-point locking systems feature a door handle, panic door fitting, or push bar on the inside of the door. There is also a door handle on the outside. When locked, the door cannot be opened from the outside, but can always be opened from the inside using the door handle, panic door fitting, or push bar (panic function). The square (cam) is split for the 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 with a key turn in the opening direction until it reaches the stop, at which point the door handle on the outside is engaged. When day operation is deactivated, the lock automatically engages (self-locking). It can be used in combination with the stand leaf locking systems 50590 or 51590 in double-leaf doors.
