Operation
Operating concept
Each of the 6 symbol buttons on the control panel
(Figure 2) corresponds to a touch-sensitive sur-
face. To trigger its function, it needs a push-button
press with tactile feedback.

Application 1: Door call
Outside on the door station the assigned call
push-button is pressed.
The indoor station signals a door call:
The ring tone melody sounds.
The LED ashes and the lights up.

Ring tone and LEDs signal the door call for a
max. of 90 seconds.
Accepting door call and establishing call
Press the speech button .
A call to the door station is established.
The LED lights up permanently. The call
connection is established (max. call duration
3 minutes).
To end the call, press the speech button again.
Call connection and video connection are
terminated.
or:
Open door
Press door opener button.
The door of the calling door station is unlocked
and can be opened. An active call is terminat-
ed automatically approx. 10 seconds after the
unlocking.

Direct door release: In systems with only one
door station, the door can be unlocked even
without a preceding door call if the door station
has been congured accordingly.
Switch-on lights
The light (e.g. stair light) can be switched on if the
associated automatic light is connected to the line
power supply with relay.
Press light button.
The light is switched on1).
1) requires a corresponding installation
Mute ring tone
The ring tone can be muted if necessary.
The indoor station is in standby mode.
Press the mute button.
The LED ashes. The ring tone melody is
deactivated.
Press the mute button once again.
The LED goes out. The ring tone melody is
reactivated.

The mute function should only be used as
briey as possible in order not to miss any door
calls.
Application 2: Storey call
If the storey bell push-button connected to the
indoor station is pressed,a storey call is signalled:
The ring tone melody for the storey call sounds
on the indoor station.

If, in the apartment or building unit (i.e. in the
same system branch), up to 2 further, identically
addressed indoor stations are installed, these
also signal the storey call (storey call forward-
ing3)).
3) requires the appropriate default setting by the installer
(see setting operating modes)
Application 3: Internal call3)
In the door communication system, internal calls
from indoor station to indoor station are possible.
The internal call function uses the xed addresses
F/E or F/F as call destination. The and but-
tons are congured for this purpose (Table 1).
Initiating internal call
The indoor station is in standby mode (no call).
The internal call address F/E or F/F is set on the
indoor station to be called.
Press the speech button .
The dial tone for internal call sounds (recurring
tone sequence from 3 identical tones).
The LED lights up.
Press the button to call the indoor station
with address F/E.
or:
Press the button to call the indoor station
with address F.
After the button is pressed, an acknowledge
tone can be heard.
If the internal call on the indoor station receiving
the call is accepted, the call connection is
established.
Pressing the speech button again termi-
nates the connection on one of the two indoor
stations.
3) requires the appropriate default setting by the installer
(see setting operating modes)
Audio settings (Figure 3)
Setting the microphone sensitivity
During an active call connection, the microphone
sensitivity is adjustable.
Keep + buttons pressed simultaneously
for 3 seconds.
The setting mode activates itself with an ac-
knowledge tone. The call connection remains
active.
Adjust the microphone sensitivity incrementally
with / .
Each of the 5 adjustment levels has its own ac-
knowledge tone. The higher the tone, the higher
the microphone sensitivity.

In hands-free mode, the changeover between
listening and speaking takes place automatical-
ly depending to the volume. The changeover
behaviour can be optimised by adjusting the
microphone sensitivity. As a result, the inuence
of background noise in the area of the indoor
station can be reduced.
Activating Push-to-Talk
In Push-to-Talk mode the changeover between
listening and speaking takes place manually with
the speech button.
Speech button Function
keep pressed speak
release listen
short press end call
During an active call connection, keep the
button pressed for more than 2 seconds.
For the current call, hands-free mode is
changed to Push-to-Talk mode.

Selecting and assigning ring tone melodies
You can choose from 16 ring tone melodies. Indi-
vidual ring tone melodies can be assigned for door
calls, storey calls and internal calls. The melody for
the station that made the last call or the connected
storey push-button is always set. A separate melo-
dy that can be changed is already preset for storey
calls and internal calls.
The indoor station is in standby mode.
Keep + buttons pressed simultaneously
for 3 seconds.
The setting mode activates itself with an ac-
knowledge tone.
Press button.
The current ring tone melody sounds.
With / listen to other ring tone melodies
until the melody sounds that you wish to use.
Assign the ring tone melody with the button.
The setting mode is completed.

Afterwards, another call event can be gener-
ated, e.g. storey call, and a separate ring tone
melody can be assigned to this according to the
same procedure.
Increasing/decreasing ring tone volume
The ring tone volume can be adjusted in 3 levels.
The indoor station is in standby mode.
Keep + buttons pressed simultaneously
for 3 seconds.
The setting mode activates itself with an ac-
knowledge tone.
Press button.
The current ring tone melody sounds.
Adjust the ring tone volume incrementally with
/ .
With the button save the setting and
terminate the setting mode.
Information for electricians
Addressing and default 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).

device address
(7) DIP-switch for operating modes
Addressing the device
The indoor station can be addressed quickly and
easily using both address rotary switches (5), (6).
The address to be set is 2-digit, comprising group
address and intercom device address. It must be
identical with the address of the associated call
push-button on the door station. Figure 5 shows
the structure of the address by way of example:
[0 ... F]
[0 ... F]

(6)
Figure 5: Example address “1/E”
On the black rotary switch (5) set the group
address [0 ... F].
On the blue rotary switch (6) set the intercom
device address [0 ... F].

A maximum of 3 indoor stations with the iden-
tical address setting may be installed for the
parallel operation.

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 modes
Set the DIP-switch for operating modes (7)
according to Table 2 below.

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.

Recommended installation height: 1.5 m.
Separate supporting element (8) on the pre-
determined breaking point from the supporting
plate.
For installation on a wall box (Figure 6):
Mount the supporting element (8) onto wall box
so that the smooth surface is pointing straight
ahead and the outer cable tie mounts (9) are
lying on the screw domes of the wall box.
Pre-align supporting element with 2 screws.

For surface-mounting without wall box:
Mark the xing holes with supporting plate (3).
Observe alignment marks.
Drill xing holes and insert dowels.
For both installation modes:
Run the stripped 2-wire bus cable through the
middle opening (10) 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.

For detailed system connection diagrams and
information about cables see operating instruc-
tions of the line power supply.
Connect the stripped wires of the 2-wire bus
cable to the connecting terminals X/X.

Both terminals X/X are each implemented twice
(bridged) for incoming and outgoing 2-wire bus
cables (Figure 7).
If the indoor station is not the last intercom
device in the branch/line, then remove the
terminating resistor/terminator (12) from the
terminals X/X.
Connect the associated storey push-button to
the connecting terminals R/R.

The terminals S/S are used for connecting the
additional power supply, if necessary.
Mounting indoor station (operating unit)
(Figure 9)
Mount design frame (2) in correct position on
the back of the operating unit.
