Conguration of In-Home: Video
The basic Siedle In-Home bus instal-
lation type is the single line system.
Within this one line, installation
takes place from one device to the
next, provided this is allowed by the
building installation.
In buildings with a side circuit and
individual branches into the apart-
ments, the bus video distributor
must be used. A maximum of 31
users are admissible within any one
line. Users are dened as devices
which occupy their own address
within the bus. If more than 31 users
are required, additional lines must be
congured. With only a few excep-
tions, all devices are assigned an
address. Up to 15 lines with 31 users
each can be congured.
Camera branch and monitor
branch
Within a line, a distinction is made
between the camera branch and the
monitor branch. Video door stations
are connected to the camera branch,
while bus telephones with video are
connected to the monitor branch. If
the installation requires an additional
monitor branch, so-called bus dis-
tributors must be used.
Users without video
In the case of In-Home: Video, audio
users can only be connected via a
bus audio decoupler BAA 650-... .
Switching and control devices are
also connected to the BAA 650-... .
Power supply
The nerve centre of every line is the
bus video line rectier, which con-
trols all the system functions. The
camera branch and monitor branch
are connected to it via separate
terminals.
Conductor material
Telecom or light current cables can
be used for the the installation:
J-Y(ST)Y twisted pair
conductors, shielded
A2Y(ST)2Y buried
telecommunication
cable
YR light current conductor
Core diameter 0.8 mm
The In-Home bus must be installed
on one pair of cores for J-Y(ST)Y
conductors, on two adjacent cores
for YR conductors.
Using J-Y(ST)Y conductors reduces
the likelihood of interference.
Conductor length
Conductor material YR cable with
0.8 mm diameter:
• max. 100 m from the bus video
line rectier to the most distant user
in the monitor branch
• max. 100 m from the bus video
line rectier to the most distant user
in the camera branch
With a core diameter of 0.6 mm, the
range is halved.
Within the line, the maximum
length of the conductor material
must not exceed 1,500 m.
When using J-Y(ST)Y conductor
material, longer ranges can be
achieved. Installation using J-Y(ST)Y
is described in detail on page 11.
When installing, ensure without fail
that the camera branch and monitor
branch are not laid in the same
cable. Forward and return lines to a
bus telephone with video must not
be laid in the same cable.
Otherwise, picture disturbance may
result.
If installation from one bus
telephone to the next bus telephone
is not possible, bus distributors must
be used. In this case, attenuation of
the conductor material and bus
distributors must be additionally
taken into consideration.
