Installation of the 627 series buttons is quick and easy, thanks to the mounting ring and adapters without screws or bolts
Contact blocks and light sources can be easily attached to the adapter thanks to the side levers
Contact blocks are mounted on the outer sides of the adapter or in stacks (maximum 2 floors per button). The light source must be placed centrally in the adapter.
The anti-rotation tab on the button body and the mounting ring make installation faster and easier
No tools required for assembly. Contact blocks and light sources are mounted without screws.
The minimum depth for mounting the 627 buttons is only 45mm
