Emergency Function









If a key is in the lock on the opposite side and turned while the door is closed, it is nevertheless possible to operate the profile double cylinder.

This means that an entrance door can be opened from the outside at any time. This special safety feature can be of vital importance if, for instance, children in the house cannot open the door or if sick people cannot get to the door.


This use of quality-tested protective trims with cylinder protection is recommended in order to achieve optimum protection of profile cylinders in intrusion-prone doors.


Profile cylinders with integrated lock cylinder wrenching-out protection should be used in conjunction with protective trims with a profile cylinder hole.
