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 fitted) and test

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 configured 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-configured 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-
configuration to be carried out correctly.
The device is automatically configured when it
is switched on in a 1st Edition system. Program
the door phone after installation.

The door phones called from
this station will only ring if
they were programmed from

attenuated with possible
Larsen effect.
The switchboard cannot

no voice and the door
cannot be opened.
The other main stations do
no switch to busy when this
station is calling.
The door phones of other
columns can be called by
this station but there is no

switch to busy.
The door phone cannot be
called by the column
secondary (e.g. 1001 cannot
