The internal bus video station
BVI 750-0 is a combination of In-
Home bus audio and monochrome
video unit including bus video
receiver as a surface wall-mounted
device with a 4” diagonal screen.
Classical installation can be
performed using a side circuit, or by
looping.
Important notes:
!
•Electrical appliances may only be
mounted and installed by suitably
qualified electricians.
•The device may only be opened
when disconnected from the power
supply.
•In order to prevent injury, the
device must be fastened reliably in
accordance with the installation
instructions either on the floor or on
the wall.
•The BVI 750-... cannot be used in
conjunction with Multi, 1+n or 6+n
technology-based systems.
•The forward and return feed
cables must be separately routed.
• If an electrically adjustable camera
is used, the BVI 750 and BTS/BTC
750 with MOM/MOC 711 should
not be mixed in one and the same
system.
•The camera cannot be controlled
from the BVI 750-... .
• It is not possible to retrofit a video
memory module.
•A maximum of 8 BVI 750-... units
can be connected in parallel.
•Where units are connected in
parallel, the first BVI 750-... receives
its power supply from the bus. For
all other units, a separate
VNG 602-... must be used for each
group of 3 BVI units.

Mounting
2Open the housing by exerting a
light pressure on the concealed
spring tabs with a size “1”
screwdriver through the release
holes on the right-hand side.
3Hinge open the cover panel to the
left, detach the ribbon cable with
the non-reversible plug “S1” from
the main circuit board and remove
the cover panel.
4 Feed the connecting cables into
the base of the housing and fasten
the base using 4 screws.
5Connect to BVI 750-... in
accordance with the circuit diagram
Circuit diagram note:
!
1) For details of the internal wiring
of the door loudspeaker, refer to
product information BVSM 650-...!
2) With the TR 602-... pay attention
to the total simultaneously
admissible load.
7) An additional VNG 602-... is only
required if devices are switched in
parallel. One VNG 602-... is required
for each started group of 3
BVI 750 -... units.
8) If the installation is looped
through from BVI to BVI, at the last
BVI 750-... the combination of
resistor and capacitor must not be
removed at terminals TaM, TbM.
9) The power supply to a BVI 750-...
is provided by the VNG 602-... from
the In-Home bus.
6(not illustrated)
Close the internal station.
Plug the ribbon cable of the housing
cover into the main circuit board
(S1), attach the cover on the left
hand side, hinge down on the right
and clip into place.

Call volume regulation
Using a size “1” screwdriver, it is
possible to set the required call
volume at the potentiometer on the
underneath of the housing.

Brightness/contrast controllers
These are located on the underneath
of the device at the left.
