3. CONNECTION
Note!
Make sure floor video switcher 10-825 is not energised before installing it. Do not
connect the device to the mains until installation is complete.
Connect the floor video switcher as shown in the
connection diagram
in Fig. 2 on
page 24.
If you have a
6-wire system
, connect the
M
wire of the other system components to
terminal
b
of the floor video switcher. The floor video switcher also works if the M wire is
not connected.
Notes
• A floor video switcher 10-825 is required for each video internal unit in a house
equipped with a floor video external unit.
• The video signal from the main video external unit must via a splitter be distributed to
the different floor video switchers. Only one floor video switcher can be connected to
each splitter output.
4. PROGRAMMING
To ensure that the image from the correct video external unit is displayed on the video
internal unit, programme the
addresses
of the different video external units with the
service unit
.
Use
external unit addresses 0 up to and including 31
for a video external unit or an
audio external unit with external camera. In this way, the video internal unit knows that
the image must be activated in the event of a call.
Use
external unit addresses 32 up to and including 63
for audio external units with
no external camera. In this way, the video internal unit knows that the image must not
be activated in the event of a call.
Notes
• To assign
another ring tone
to one of the video external units, use
address 0
for
that video external unit.
•
No external unit address
can be assigned to an
external camera
.
If you connect the external camera to an audio external unit, you must assign an
external unit address between 0 and 31 to the audio external unit
To programme the floor video switcher, you must first programme the video internal unit
on the bell push button of the external unit.
