Siedle In-Home: Audio
„Single line“
Conguration
The In-Home bus: The Audio system
comprises a bus installation with a
two-core line permitting the con-
nection of up to 31 users, e.g.
bus telephones, handsfree bus
telephones, door stations or devices
for switching and control functions.
Technically speaking, one device can
occupy more than one user.
The line has its own bus line rectier
for central functions such as speech,
door release or light switching. The
two cores assume the dual func-
tions of power supply and also
transmission of audio, switching
and control signals. Junction points
and branches are admissible at any
optional position in the line. In order
to connect more than 31 users, sev-
eral Siedle In-Home: Audio lines can
be interconnected.
Installation and programming
In their as-delivered status, the
devices are initially unprogrammed.
After the bus line rectier is switched
on for the rst time, each of the
connected devices is assigned to a
unique address on the line.
Once installation is complete, a
mutual „teach-in“ process between
all the devices must be performed to
ensure that functions are correctly
executed (e.g. the bus telephone
rings as soon as the call button is
pressed).
Siedle In-Home: Audio
„Multiple line“
Conguration
In-Home: Audio „Single line“ is
restricted to 31 users; In order to
connect more than 31 users, up to
15 lines can be coupled together.
Each line requires its own bus
line rectier. Junction points and
branches are admissible at any
optional position in the line.
Installation and programming
To couple lines together, the bus line
rectiers are linked by means of two
separate cores. Different addresses
must be set at the bus line rectiers
using the “Adr.” rotary switch.
The bus supply unit accessory
ZBVG 650-... must be plugged into
one of the bus line rectiers within
the system.
Then proceed using the same
method as for the In-Home: Audio
single line system.
Mounting, installation and servicing
work on electrical devices may only
be performed by a suitably qualied
electrician. Failure to observe this
regulation could result in the risk of
serious damage to health or fatal
injury due to electric shocks.
When working at the device,
observe the remarks relating to
mains cut-off.
• Observe the DIN EN 60065
standard! When establishing the
electronic connection, observe the
requirements of VDE 0805 or
EN 60950.
• The building installation must
include an all-pole mains switch
with a contact separation of at least
3mm.
• Ensure maximum fusing of 16A for
the mains connection in the building
installation.
• When planning large-scale
(complex) systems, the distributor
space required for the switch panel
mounting devices must be taken
into consideration in the distributor
planning process.
• No external voltages >30 V AC/DC
may be applied to bus users.
Devices with 230 V connection
In accordance with DIN VDE 0100
part 410, section 411.1.3 atten-
tion must be paid to ensuring a
safe separation between bus lines
and the mains voltage; i.e. bus and
mains cores must not be permitted
to touch! The bus line cable (extra-
low safety voltage) must be stripped
back by the minimum possible.

Conguration of In-Home: Audio
The basic installation of In-Home-
Bus: Audio takes place as a single-
line system. Within this line, the
users are installed on the bus cores.
A maximum of 31 users may be
connected to one line. Users are
classied as devices occupying an
address within the bus (see overview
on the right). If more than 31 users
are required, additional lines must be
congured. Apart from a few excep-
tions, all the devices have an assi-
gned address. Up to 15 lines each
with 31 users can be congured (in
theory a maximum of 465 users).
Power supply
The nerve centre of any line is the
bus line rectier, which controls the
entire function of the system. The
bus cores are connected to the bus
line rectier.
Conductor material
Telecommunication or light current
conductors can be used for instal-
lation:
J-Y(ST)Y Twisted pair conduc-
tors, shielded
CAT Network cable
A2Y(ST)2Y Buried telecommuni-
cation cable
YR Light current con-
ductor core diameter
0.8 mm
The In-Home bus must be installed
on one pair of cores when using
J-Y(ST)Y, and when using a YR
conductor, on two YR cores posi-
tioned side by side. Using J-Y(ST)Y
conductors reduces the likelihood of
interference.
Conductor length
• Conductor material J-Y(ST)Y or YR
conductor with 0.8 mm diameter:
• max. 300 m from the bus line rec-
tier to the most distant door station
• max. 300 m from the bus line
rectier to the most distant bus
telephone.
• Conductor material J-Y(ST)Y or YR
conductor with 0.6 mm diameter:
• max. 150 m from the bus line rec-
tier to the most distant door station
• max. 150 m from the bus line
rectier to the most distant bus
telephone.
• A maximum of 1500 m of ins-
tallation cable may be laid within
the line.

Conguration of In-Home: Audio
with intercom function
Using the handsfree bus telephone
BFC 850-..., internal building com-
munication can be supplemented
to include additional convenience
functions.
• Internal call with callback function
• Automatic call pick-up of internal
calls
• Internal group call (max. 8 devices)
• Collective paging announcement
(*only with supplementary supply
and accessories)
For the paging announcement
intercom function, an accessory is
required in each handsfree bus tel-
ephone BFC 850-... . This permits a
direct voltage power supply directly
to the handsfree bus telephone.
Using handsfree bus telephones,
communication is possible without
lifting the receiver. From a handsfree
bus telephone, it is possible to call
devices both with and without a
receiver. Intercom functions are only
possible within a line. Door calls
have priority over internal calls.
In order to utilize the intercom
functions, the system must be pro-
grammed at the PC.
Power supply
The nerve centre of any line is the
bus line rectier, which controls the
entire function of the system. The
bus cores are connected to the bus
line rectier.
*) A supplementary power supply
using a line rectier or video line
rectier is only necessary in the case
of collective paging announcements
or parallel calls with more than two
users.
Conductor material
Telecommunication or light current
conductors can be used for instal-
lation:
J-Y(ST)Y Twisted pair conduc-
tors, shielded
CAT Network cable
A2Y(ST)2Y Buried telecommuni-
cation cable
YR Light current con-
ductor core diameter
0.8 mm
The In-Home bus must be installed
on one pair of cores when using
J-Y(ST)Y, and when using a YR
conductor, on two YR cores posi-
tioned side by side. Using J-Y(ST)Y
conductors reduces the likelihood of
interference.
Conductor length
• Conductor material J-Y(ST)Y or YR
conductor with 0.8 mm diameter:
• max. 300 m from the bus line rec-
tier to the most distant door station
• max. 300 m from the bus line
rectier to the most distant bus
telephone.
• Conductor material J-Y(ST)Y or YR
conductor with 0.6 mm diameter:
• max. 150 m from the bus line rec-
tier to the most distant door station
• max. 150 m from the bus line
rectier to the most distant bus
telephone.
A maximum of 1500 m of instal-
lation cable may be laid within the
line.

Conguration of the multiple
line system
A multiple line system comprises
individual lines which are linked
together by two cores. The lines
are connected at the bus line recti-
er using terminals Sa and Sb. In
multiple line systems, door calls and
control functions are possible from
one line to another.
Differentiation line 1,
line 2 ... up to max. line 15
The lines are consecutively num-
bered with the address switch
“Adr.” at the bus line rectier. Up
to 15 lines can be connected via
the cores Sa and Sb. The bus supply
unit accessory ZBVG 650-... must
be plugged into one of the bus line
rectiers within the overall system.
When installing, ensure that every
line is laid in its own cable.
Conductor length between the
lines
The admissible conductor lengths
within a line are identical to those in
a single line system. The conductor
length between the bus line recti-
ers must also be taken into consid-
eration. This may not be more than
300 m between the most distant bus
line rectiers.
Functions applicable across indi-
vidual lines
Door calls, selective door dialling and
switching and control functions can
also be used across line boundaries.
Internal speech communication and
call forwarding between users is only
possible within a line.

Bus call button module
Connection of the bus call button
modules to the bus door loud-
speaker via ribbon cable. The name
plate lighting is supplied from the
terminal block of the BTLM650-04.
If there are more than 20 illuminated
bus call button modules with LED
lighting (BTM 650-01, -02, -03, -04),
these must be supplied via an addi-
tional transformer with 12 V AC if a
door release is operated within the
system.
Bus line rectier
At bus line rectier BNG 650-0,
the operating mode selector
switch must be set to Norm in a
new system (as-delivered status). If
rst series bus telephones are used
within the line, (e.g. B. BTS/
BTC 750-0), the operating mode
switch must be set to 1. A compat-
ibility list is provided in Chapter 8,
page 76.
Using the “Adr.” rotary switch, the
address is set at the bus line rectier.
In single line systems, this is address
1 in the as-delivered status. This set-
ting does not need to be altered. In
multiple line systems, the bus line
rectiers are addressed in consecu-
tive sequence.
