Conguration “Single line“
The In-Home bus: The Audio system
comprises a bus installation with
a two-core line permitting the
connection of up to 31users, 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 rectier
for central functions such as speech,
door release or light switching.
The two cores assume the dual
functions 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 31users, sev-
eral Siedle In-Home: Audio lines can
be interconnected.
Conguration “Multiple line“
In-Home: Audio “Single line” is
restricted to 31users; In order to
connect more than 31users, up to
15lines can be coupled together.
Each line requires its own bus
line rectier. Junction points and
branches are admissible at any
optional position in the line.
Mounting, installation and servicing
work on electrical devices may only
be performed by a suitably qualied
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 EN60065
standard! When establishing the
electronic connection, observe
the requirements of VDE0805 or
EN60950.
• The building installation must
include an all-pole mains switch
with a contact separation of at least
3mm.
• 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 >30VAC/DC
may be applied to bus users.
Devices with 230V connection
In accordance with DIN VDE0100
part410, section 411.1.3 attention
must be paid to ensuring a safe
separation between system lines
and the mains voltage; i.e. system
and mains cores must not be per-
mitted to touch! The system line
cable (extra-low safety voltage) must
be stripped back by the minimum
possible.

Danger
“Siedle Systemtechnik” and the
relevant logo are used to describe
devices, components or systems
which are not manufactured
and designed by Siedle but are
tted with Siedle technology. The
Systemtechnik logo guarantees tech-
nical compatibility with the Siedle
system world. Products identied
with “Siedle Systemtechnik” may
therefore be used without restric-
tions as components of a Siedle

Jung indoor stations in switch
design
Within the framework of a cooper-
ation agreement with the company
Jung, Siedle equips Jung indoor sta-
tions with “Siedle Systemtechnik“.
Indoor stations from Jung which
bear the Systemtechnik logo on
their components, their packaging
or the product information, are fully
compatible with Siedle technology.
They are integrated in this manual as
Siedle system components.
