common installation solutions.
Up to 8 mechanical bell buttons can be con-
nected to the built-in loudspeaker. Addi-
tional bell buttons can be connected via add-
on modules. It is possible to connect up to
5 add-on modules with 12 bell buttons each.
With these door communication systems
with up to 70 audio devices can be realised,
e.g.
1 Audio control device
1 Built-in speaker with
5 Add-on modules
68 Surface-mounted, hands-free feature
home stations

Mounting
The built-in loudspeaker in mounted behind
the speech cover plate of the existing sys-
tem. Depending on the design, this is carried
out directly on the front panel or via an
installation carrier.
Attention
Installation and mounting of electrical
devices may only be carried out by a quali-
fied electrician.

Use only the screws provided to mount the
built-in loudspeaker.
When positioning the built-in loudspeaker,
make sure that both the microphone and the
loudspeaker are mounted in front of the
sound openings. Here the position of the
microphone should be given a higher prior-
ity.
The best speech quality is achieved when a
separating bar is located between the loud-
speaker and the microphone.
Connection
1. Connect the 2-wire bus to the BUS termi-
nals.
2. If necessary, fit jumpers between the BUS
and ZV terminals. This is necessary when
illuminated system components or a col-
our camera are to be operated on the
built-in loudspeaker.

4. If necessary, connect additional compo-
nents from the door communication sys-
tem via the "System" or "Video" slots.
Do not connect "0" terminal
When using an add-on module, the "0" ter-
minal of the built-in loudspeaker may not
be connected to the "0" terminal of the add-
on module.
iIllumination of bell buttons

loudspeaker to the door communication sys-
tem, flush-mounted inserts, such as a colour
camera, info module or call buttons, can also
be connected.

1. Connect the flush-mounted insert of the
colour camera with the built-in speaker
using the 2-pole video connection cable
and the 6-pole audio connection cable.
2. Fit jumpers between the BUS and ZV ter-
minals on the built-in
loudspeaker.
Info module, call button
1. Connect the flush-mounted insert of the
device to the built-in loudspeaker using
the 6-pole audio connection cable.
2. To activate the illumination of the info
module or the call button, fit jumpers
between the BUS and ZV terminals on the
built-in loudspeaker.

cation system into operation.
Commissioning is described in the system
manual included with the control device.
iNote
When commissioning large systems,
please note that a maximum of 20 bell but-
tons can be temporarily stored per work
