KP06 - the keypads and surround plate are just a push fit into the main unit - in situations where there is not an entirely flat wall behind we are experiencing the keypads coming loose.
Would it be possible to design some sort of screw fox for the front assembly.
Something along the lines of the GIRA and JUNG switches that both have 'clip' fixings BUT ALSO screws into the base unit.
I hope these don't go orange over time under exposure to indirect sunlight like my KP04's have; the white/cream discoloured badly over time! One was OK when I took of the wall and put back in the Cytech packing for a few months but was bright orange/yellow when I unpacked it again; so "bin fodder" or spare (internal) parts use only now!
