10. Remove both screws on the nameplate and take it apart; the foil
for inscription is between the plastic parts.
11. Write on the foil with a smear-resistant felt pen or print a name-
plate inlay* using a PC and a printer.
12. Place the written nameplate inlay between the two plastic parts
and screw these back together.
*Size of the nameplate:
VDV 910: 71 mm x 34 mm
VDV 920: 71 mm x 15 mm
13. In order to be able to replace the front cover on the outdoor station
first insert the nameplates into the outdoor station and fix them on
the sides using the supplied tape strips so that they cannot fall out.
Alternatively you many also fix the nameplates with transparent
sticky tape.
14. Remove the assembly aid and secure the outdoor station from
falling with your hand. A second person can help.
15. Replace the microphone plug into the circuit board and replace
the front cover on the outdoor station. Take care not to crush the
microphone cable.
1,2 Nm
16. Screw on the front cover with the relevant 4 Torx screws. Please
max.
ensure that the screws are not tilted or over-tightened. The maxi-
mum tightening torque is 1.2 Nm. This value must not be exceeded
as the threads in the flush mounted shell can otherwise become
unusable or fall out.
Note: Self-adhesive foam is supplied to seal the front plate against
water. It is affixed to the edge of the front plate from behind.
CONNECTION
We recommend a star wiring of the system as shown in the connection
example. Connect terminals A1-A4 to terminals 1-4 of the indoor units.
In the two-family version, the terminals are responsible for the lower
pushbutton (family 1). Terminals B1-B4 are for the upper pushbutton
and are connected to terminals 1-4 of the indoor unit(s) of family 2.
Door opener
At the units, the connection terminals have been reworked to simplify
installation. In addition, the door release connection was modified to
a potential-free relay output. The door opener can be connected as
follows:
1. via the operating voltage of the outdoor unit
For this purpose, connection 1 of the door release is connected to
terminal 11, connection 2 of the door release to ground / GND (e.
g. terminal A2). A bridge of +15V (e. g. A1) to terminal 10 is also
required.
2. with an external voltage source (e. g. bell transformer,
max. 15V/1A)
Separate cables from the external power source to the door opener and
to the external unit are required. Port 1 of the door opener is directly
connected to port 1 of the external voltage source. Connection 2 of the
door release is connected to terminal 11, connection 2 of the external
voltage source is connected to terminal 10.
Power supply / Initialization
We recommend feeding the power supply at the star point, as shown
in the connection example. If this is not possible, the power supply
can also be connected directly to the outdoor or indoor unit. The power
supply is then connected to terminals A1 and A2 or terminals 1 and 2.
The positive pole is connected to terminal A1 (or 1), the negative pole
to terminal A2 (or 2).
If there are more than two indoor units connected in parallel, we
recommend using the DT 2000 DIN rail power supply unit. In individual
cases, a second power supply may be necessary. If this is the case,
connect the second power supply to the furthest distant unit.
After connecting the power supply, the system must be initialized.
Do not press a key on the indoor units yet.
To initialize the system, press a bell button on the outdoor unit. All
connected indoor units will ring briefly. The system is then ready for
operation. This procedure must be carried out each time the power
supply is disconnected.
NOTE: In case of image and/or sound interference, the following
measures can help to eliminate the interference:
Connect the ground / GND cable to the equipotential bonding bar.
Connect the shielding of the line at the neutral point to the equipo-
tential bonding line, in this case the ground / GND line must not be
connected to the equipotential bonding line.
In rare cases, the shielding must be connected to ground (GND) and/or
the equipotential bonding shield on both sides.
Connecting an external camera
An external camera can be connected to this screw terminal (figure 2)
in order, for example, to provide additional monitoring of areas that
cannot be seen by the main camera. All cameras can be connected that
require operating voltage of 12 V DC and supply an FBAS video signal.
The video line is connected to the terminal (VIDEO IN) and the earth
line to the terminal (GND), operating voltage for the camera is taken
from the terminals '+12V DC OUT' (positive pole) and 'GND' (negative
pole).The external camera automatically has the ID 4 (see chapter
on ID code).
No sound transmission is possible when the external camera is active.

POSSIBLE SETTINGS

The outdoor station offers the following possibilities to set the system
to your personal circumstances:
Volume of the outdoor station
The potentiometer (7) is used to set the volume on the outdoor station.
To set the highest volume, turn the potentiometer carefully clockwise
as far as possible. Reduce the volume by turning in an anti-clockwise
direction.
ID code
If several outdoor stations are switched in parallel (e.g. at the gate ent-
rance and the house) then the ID code is set via the dip switch (9). This
makes it possible to activate the individual outdoor units in sequence,
e.g. in order to monitor the coverage of the relevant outdoor unit. The
switch is carried out on the indoor station with the 'monitor' switch.
ID1 = Switch 1 'on' Switch 2 'on'
ID2 = Switch 1 'off' Switch 2 'on'
ID3 = Switch 1 'off' Switch 2 'off'
