AS-TVHa-2/1 multiple line system

Mode of operation

Calling, speech and video between
the door station and the connected
bus telephones BTSV/BFSV/
BTCV 850-... with colour monitor.
Audio and video privacy of existing
calls is assured. Door release button

button for the light switching
function. Pressing the monitor
button will show the camera picture
from the door station which placed

only possible if no call exists.
Connection of a storey call button
(ERT) for calling from an apartment
door. Ring tones can be selected for
calls from the front door, apartment
door or internal calls.
Connection of other bus telephones
with colour monitor when looping
through from one device to the
next. Other bus door loudspeakers
with video are connected with bus
video distributors BVVU 650-... or
BVVS 650-... .
In a multiple line system comprising
only 2 lines, connection between the
two bus video line rectifiers is
possible without bus distributor
BVVU 650-... . Up to 15 lines can be
linked via BVVU 650-... .

can supply 1 door release button
and max. 24 bus call button
modules with LED lighting
(BTM 650-01, -02, -03 and -04).
With more than 24 illuminated bus
call button modules, an additional

20 Ohm, (e.g. TÖ 615-...), for
possible connection variants see
chapter 8, page 80.

used for this purpose. Connection of
the supply at terM/-M. For

more information, see chapter 8,
page 82.

Installation

In each bus telephone with colour
monitor, there is a terminating
circuit board connected in the as-
delivered status in the centre of the
connecting terminals TaM and TbM.
This circuit board is an RC element
which comprises a resistor with
100 Ohm and a capacitor 1 nF.
When looping through from one bus
telephone to the next in the
installation, this terminating circuit
board must be removed. If,
however, bus distributors are used in
the installation, or if there is only 1
bus telephone with colour monitor
in the line, the terminating element
remains in the bus telephone.

Terminal
BTSV/BFSV/BTCV 850-0

Connection for

one bus telephone

or the last bus telephone in the line.

Connection when looping

through from one bus telephone to
another.

Cable laying

Only signals from the In-Home

bus may be transmitted via the laid
conductor material. No additional
transmission is possible, for instance
to PBX extensions of a telephone
system or an S0 bus (ISDN). The
camera branch and monitor branch
must be laid in a separate cable and
must not be installed inside the
same conduit. This can result in
disturbance to the picture
composition.
