Information for electricians
Addressing and pre-settings
The device addressing and setting of the operating
modes must already be carried out prior to installa-
tion using the rotary switch and DIP-switch on the
back of the device (Figure 4).

Addressing the device
The indoor station can be addressed quickly and
easily using both address rotary switches (13),
(14). The address to be set is 2-digit, comprising
group address and intercom device address. It
must be identical with the address of the associ-
ated call push-button on the door station. Figure 5
shows the structure of the address by way of
example:
[0 ... F]
(14)
(13)
[0 ... F]
Figure 5: Example address "1/E"
„ On the black rotary switch (13) set the group
address [0 ... F].
„ On the blue rotary switch (14) set the intercom
device address [0 ... F].
i A maximum of 3 indoor stations with the iden-
tical address setting may be installed for the
parallel operation.
i
For door stations with automatic call push-but-
ton addressing also see operating instructions
of the door station. For door stations with
push-button interface/expander see operating
instructions of the interface.
Setting operating mode
„ Set the DIP-switch for operating modes (15)
according to Table 4.

Installation and electrical connection

The supporting plate (3) must be mounted on the
wall before wiring.
Mounting the supporting plate
A 2-wire bus cable, and if necessary, a connection
cable of the storey push-button are laid to the
mounting location.
i
Recommended installation height: 1.5 m.
„ Separate supporting element (16) on the pre-
determined breaking point from the supporting
plate.
(15)
For installation on a wall box (Figure 6):
„ Mount the supporting element (16) onto wall
box so that the smooth surface is pointing
straight ahead and the outer cable tie mounts
(17) are lying on the screw domes of the wall
box.
„ Pre-align supporting element with 2 screws.
(17)

(18) Opening to the cable bushing
For surface-mounting without wall box:
„ Mark the fixing holes with supporting plate (3).
Observe alignment marks.
„ Drill fixing holes and insert dowels.
For both installation modes:
„ Run the stripped 2-wire bus cable through the
middle opening (18) of the supporting plate.
„ Also run the connection cable of the associated
storey push-button through.
„ Mount the supporting plate (3) onto the wall
or wall box with at least 2 screws. Observe
alignment marks.
Connect device
Figure 7 shows a schematic view of the connection
from the video indoor stations to the system line
power supply:

Wrapped wire pair for 2-wire devices (recom-
mendation: white/yellow wire pair)
Additional audio and video stations can be con-
nected according to this principle.

For detailed system connection diagrams and
information about cables see operating instruc-
tions of the line power supply.

(20) Terminating resistor/terminator
„ Connect the stripped wires of the 2-wire bus
cable to the connecting terminals X/X.
i Both terminals X/X are each implemented twice
(bridged) for incoming and outgoing 2-wire bus
cable (Figure 7).
„ If the indoor station is not the last intercom
device in the branch/line, then remove the
terminating resistor/terminator (20) from the
terminals X/X.
„ Connect the associated storey push-button to
the connecting terminals R/R.
i
The terminals S/S are used for connecting the
additional power supply, if necessary.
