Caution
Make sure that the diameter of the dowel holes is accurate to avoid falling out of
the dowels! Use the mounting glue to secure the dowels if necessary.
Make sure that the depth of the dowel holes is accurate!
Do not use low-quality dowels to avoid falling out of the dowels of the wall!
Having removed the front panel, make sure that no dirt gets inside the product
(especially onto the sealing surface).
Never turn an assembly of
2N Access Unit devices after mounting. Make sure that
the flush mounting boxes have been installed accurately.
Check the plasterboard wall and room interior pressure values. If the difference
between the values is too great (as a result, e.g., of overpressure ventilation),
separate the intercom using, for example, the mounting box enclosed and seal the
cable passage.
Surface mounting may cause problems on places exposed to potential vandalism
(such as public garages, etc.). In this case, use steel anchoring elements instead of
the dowels and screws included in the delivery.
The wall mounting surface must be flat with the maximum inequality of 0.5 mm
(e.g. prefabricated boards, glass, cut stone, etc.). If the surface is uneven, use flush
mounting and a backplate,
Part Nos. 9155061 – 9155062 , or equalise the wall
surface.
