Montage
Note
The line rectifier is also used in con-
nection with video to supply all
video components. For further infor-
mation about the unit, how it
operates and wiring diagrams for
video communication systems, see
"Video Systems part 1 and part 2,
edition A".
Application
For supply of a maximum of 4 con-
nection units in voice-operated
duplex communication systems in
conjunction with the Siedle Intercom
SIC 3000-... . For information on
functional charac- teristics, appliance
requirements and circuit diagrams,
see the "Siedle Intercom Planning
and Installation" instructions.
1 System Structure
In its simplest form, a system
consists of a bus (global bus), to
which up to 99 appliances can be
connected. If a system is structured
in such a way that more appliances
are required, or that it has to be
divided, additional buses (local
buses) are required. Each local bus
can also accommodate up to 99
appliances. Of the 99 permissible
appliances per bus, however, only
25 may be speaking stations.
The maximum configuration of a
system consists of a global bus with
a maximum of 99 appliances and up
to 25 local buses with a maximum of
99 appliances each.
To connect a local bus to a global
bus, a Bus Controller BC 3000-...
is always required.
Installation
Caution!
Installation and mounting may
only be carried out by a qualified
electrical installer.
Important!
Please observe the standard DIN
EN 60065!
For building installation, an all-pole
mains switch with a contact gap of
at least 3 mm must be provided.
The device must not be exposed to
splash or spray water!
Ensure sufficient ventilation, paying
particular attention not to cover up
the vent holes.
Attention!
a If the terminals 9 and 10 are con-
nected together in an Intercom
SIC 3000 system but without music
feed-in, then a bridge must be
placed between terminals 9 and 10.
b If the terminals 9 and 10 are not
connected together, then a bridge
between terminal 9 and 10 must
be placed on every SIC 3000-... .
Conductor material
Telecommunication conductors must
be used for installation at the bus.
JY (St) Y twisted-pair
conductors,
shielded, 0.8 mm
(20AWG) wire
diameter
A2Y (St) 2 Y telecommunication
earth cable, 0.8 mm
(20AWG) wire
diameter
The mains supply line must be provi-
ded in accordance with VDE 0100.
For cable size diagrams and wiring
diagrams, see the "Siedle Intercom
Planning and Installation"
instructions.
The cable size diagramm indicate the
necessary numbers of cores. Reserve
wires to permit retrofitting of func-
tions must be provided for.
Conductor lengths/range
The loop resistance with a 0.8 mm
(20AWG) wire diameter is 8 Ω/km.
The voltage drop is 0.16 V/10 m
(11 yds) per SIC 3000-... .
The minimum voltage level of
20 V DC must be ensured at all the
intercom appliances.
For simple installation structures, i. e.
consisting of only the global bus, the
laid conductor length of the entire
bus is max. 1000 m, including all
branch feeders.
In installations comprising several
buses, the laid conductor length per
bus is restricted to 400 m.
