4. Test the columns by calling from the respective
secondary stations.
5. Test the main stations by making at least one
call in each column.
6. Program the switchboard (where fi tted) and test
it, verifying concierge services.
7. Program the special decoders (where fi tted) and
verify operation.
Note: Coupler 1072/24 does not
programming. The type of system (1st
Edition or 2nd Edition) does not need to
be programmed for door phones, PABX
interfaces and special decoders because
these devices be confi gured according to
the system type automatically.
TROUBLESHOOTING MAIN SYSTEM
PROBLEMS
1) One or more LEDs on the bus coupler (Ref. 1072/24)
are off.
Presence of short-circuit in the corresponding
bus coupler door phone spine.
2) The following message appears on the main
calling module or switchboard display: "NO
CONNECTION".
Presence of short-circuit on push-button side
bus circuit (L1, L2) or not only one bus coupler
is programmed as master.
3) The main door unit with digitiser does not work
(e.g. no courtesy tone after a calling button is
called).
Presence of short-circuit on push-button side
bus circuit (L1, L2) or not only one bus coupler
is programmed as master.
4) Installation of door phones. Door phones
1172/31 and 1172/32 are self-confi gured in the
system for 1st or 2nd Edition operation.
Before installing a door phone in a BiBus 2nd
Edition, power down the respective coupler
corresponding to the door phone column for
correct synchronisation of the system, reconnect
power and program replaced door phone.
Alternatively, the door phone can be installed
when the system is powered but in this case
at least one call must be made from a calling
station or switchboard in the system for auto-
confi guration to be carried out correctly.
The device is automatically confi gured when it
is switched on in a 1st Edition system. Program
the door phone after installation.

TO BUS COUPLER WITH TRANSFORMER
BIBUS 2ND
Ref. 1072/24
PERFORMANCE
• Powers the two-wire bus on main push-button
panel side: up to 12 stations + 1 switchboard.
• The bus on door phone side is called the "column"
and is split into two spines. The two spines are
reciprocally equivalent and can be separately cut
off in the case of a failure. This event is indicated
by the two LEDs corresponding to the spines.
• Powers the column (two spines and two wires):
max. 50 door phones + 1 secondary push-button
panel. Up to 30 door phones + 1 secondary push-
button panel can be connected if open door LED
feature is provided. In this case, an additional
coupler cannot be used to increase the number of
door phones in the column if this is connected to
a secondary call station.
• Repeats the data between the two buses.
• Provides bus line impedance on main push-
button panel side and door phone side to allow
audio modulation.
• Provides the current needed to generate the door
phone call and the fl oor call.
• Couples the voice of the two buses.
• Powers electrical door lock and name tag lights.
• Equipped with low voltage relay for controlling
"staircase lights".
• Equipped with VOP video power unit controller
(1074/20).

(1) Disconnect the mains power for at least 60
seconds to reset the power unit if the PTC trips
due to overload or short-circuit.
INSTALLATION AND CONFIGURATION
Install the coupler in a dry place. Keep slots open
to prevent overheating the device. Do not install the
coupler near devices generating strong magnetic
fi elds.
The device can be fi tted on a DIN EN 43870 bar (12
modules).
The coupler is confi gured as a slave by default.
Insert the specifi c plug provided to confi gure the
coupler as a master. Only one coupler can be
confi gured as a master in each system. All other
coupling devices must be confi gured as a slave.
Each coupler can be connected to up to 50 door
phones (including door phones in parallel) in two
spines.
