Installation conditions
▸
The perfect installation height for your device
is a position that enables operating the door
intercom at a distance of 30-50 cm so the user
can easily speak into the microphone. The
same applies to the use of a camera in this
intercom station.
▸
Please keep the distance between micro-
phone and speaker as large as possible. This
gives you the best possible speech intelligi-
bility in full duplex mode.

▸
For reverse-side mounting modules
(= mounting behind an existing front wall),
ensure sufficiently large sound inlet slots at
the microphone and sound outlet slots in
front of the loudspeaker (at least 75% of the
loudspeaker membrane area for sound outlet
or 75% of the sound inlet opening on the
microphone housing).
Please note our dimensional drawings on
www.behnke-online.de/downloads
For acoustic reasons, always mount the reverse-
side mounting modules directly (without spa-
cing) and firmly to the back of your front wall.
The gaskets included in the scope of delivery
of our reverse-side mounting modules must be
installed between the reverse-side mounting
module and the rear of the front wall to ensure
unobstructed sound entry and exit.
Outdoor mounting
▸
When using the operating elements on wea-
ther sides, door intercom stations should be
mounted in-wall with a rain protection cover
(please always ensure correct installation of
the supplied gasket).
▸
When mounting the door intercom stations
in surface-mounted housings, cable entry is
possible at the bottom or rear of the surface-
mounted housing. Use the fittings supplied
with the housings.
▸
The unused cable entry must be closed with
the supplied cover angle. The cable entry is
made via the PG fitting.
▸
When mounting all the stations mentioned in
these instructions in-wall, seal the top edge
of the door intercom station well to protect it
against rainwater, especially if the surface is
