Change over function

Use

For door systems that must ensure temporary passage from the inside and outside and must also be temporarily inaccessible from the outside. In principle, it is always possible to open the door from the danger side (emergency exit function).

Function on danger side (with locked deadbolt)

The door has a lever handle or touch bar / push bar on the danger side. The latch and the locked deadbolt are retracted by operating the touch or push bar. The door can be opened.

Function from outside (with locked deadbolt)

The door has a handle on the outside that can only be engaged and disengaged with a key switch.
