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 ELECTRICAL 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
columns (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 fitted)
must run in reciprocally separate conduits.
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 DEVICES IN
THE SYSTEM
The following tables show the maximum connection
lengths between the various modules in the system
and the respective cross-section area of the wires.
DS1072-021B
Door phone systems
Maximum distance (m)
Wires L1, L2, ~0, ~12 between:
- Master bus coupler
- Any device connected on
main station side
Wires L1, L2 between:
- Bus coupler
- Most distant apartment station
or special decoder
Wires L1, L2, ~0, ~12 between:
- Bus coupler
- Secondary station
Wires SE1, SE2 between:
- Calling Module
- Electrical door lock
Wire ~0 and ~12 between:
- Bus coupler
- Electrical door lock connected
to door unit with digitiser
Note: Sections shown in table refer also to use
of transformer 9000/230 (for wires ~0 and
~12).
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.
ACTIVATING THE SYSTEM
Power the system and check that the LEDs on each
coupler are on. Go to the next step if the LEDs are
on. A LED may not come on to indicate an anomaly
on the apartment station spine.
Note: The coupler will attempt to reactivate the
faulty spine approximately once a minute
for up to ten times. The faulty spine will be
cut off after ten failed attempts. To restore,
power the coupler down, eliminate the spine
problem and power the coupler again.
Program the devices in the following order:
1. Program the calling stations one by one.
Pay particular attention to the system
configuration (1st Edition or 2nd Edition) and
to the type of station (main or secondary).
2. Program the calling button user codes for button
stations.
3. Program the door phones and PABX adapters
(where fitted) from any calling station.
