In order to be able to leave a building as quickly as possible in an emergency, there are locks that have an anti-panic function. This makes it possible to leave the building even if the door is locked. People can therefore get out from the inside at any time.
There are various anti-panic functions depending on the area of usage.
Anti-panic function B
Switchover function
The locked door can always be opened from the inside using the panic function.
The outer handle is usually disengaged in idle mode. The normal function is achieved by unlocking with a key so that the door can be opened from the inside and outside.
The home position is restored by pressing the key again in the locking direction.

Anti-panic function D
access function
The locked door can always be opened from the inside using the panic function.
Once the inside lever handle has been operated, the door must also be opened automatically from the outside, e.g. so as not to hinder rescue operations. To prevent opening from the outside again, the door must always be locked again with a key.
