INSTALLATION
The following elements must be considered for
correct system construction:
• the surrounding electrical environment
• the wire type and cross-section area
• the extension of the system.
SURROUNDING
ENVIRONMENT
Construct the system respecting the safety
standards. Avoid running bus wires (main station
side bus and door phone side bus) near power lines
in the building, e.g. staircase lights, lifts, power line
risers (230Vac).
A distance of at least 10 cm is recommended.
If wires must be laid near existing power lines,
arrange a metallic partition in between, as commonly
employed in telecommunication system construction.
Important: No part of the BIBUS 2nd edition system
must be connected to electrical earth.
WIRE TYPE
Use a normal one-pole wire with a suitable cross-
section area for electrical connections. Multiple pole
wire must not be used. The main push-button panel
side bus and the door phone side bus must run
in separate conduits. Coupler spines (where fi tted)
must run in reciprocally separate conduits.

ELECTRICAL
Telephone wire terminals L1 and L2 with a diameter
exceeding 0.6 mm (AWG22) can be used for
distances less than 100 metres between calling
station and bus coupler, or between bus coupler
and most distant door phone.
MAXIMUM DISTANCE BETWEEN DOOR PHONE
SYSTEMS
The maximum connection lengths and the respective
cross-section areas of the wires L1, L2 are shown in
the following table.
Maximum distance
Between:
- Bus coupler
- Most distance

secondary station
Between:
- Bus coupler
- Main station
MAXIMUM EXTENSION OF THE SYSTEM
The sum of all the bus sections on main station bus
side must be less than 800 metres. The sum of all
the door phone bus sections of a coupler must be
lower than 800 metres.
POWER
Internal calling station circuits are power by bus
voltage.
CONNECTIONS
Up to 18 user buttons can be connected directly
to the door unit. When a higher number of user
is required, a 1038/17 expansion module can be
connected. This allows the addition of 16 user
buttons to the 18 basic buttons. Up to four expansion
units can be connected to each door unit, for a total
of 82 user buttons.
Position two call units side by side if a station with
more than 82 users is required.
The door unit is programmed by default with a
jumper between the earth and the "SP" signal
to simulate the door closed contact. Remove the
jumper and connect the sensor between GND and
SP when the open door contact is required.
