OPERATING PROBLEMS
If there is a fault, connect up a single telephone to terminals
1, 2, 3, 4 and to a push button on the entrance panel where
the anomaly is. In this way, you will be able to check whether
the problem is in the entrance panel or in the telephone
connections.
Nothing works.
Check the mains voltage in the power supply. Check that
the voltage between and
V
of the power supply is 12
Vac. Check whether there are any short circuits and fix
them. Disconnect the power supply for 1 minute and then
connect it up again.
If it still doesn’t work, disconnect all the power supply
V
and terminals, and check that the voltage between
and
V
is 12 Vac, if this is not the case then there may
be something wrong with the power supply.
The card holders do not light up.
Check that the voltage between and
V
of the power
supply is 12 Vac. Check that the voltage between 9 and
10 in the audio unit, with the lighting push button activated,
is 12 Vac. Check whether the lamp is burnt out.
The lighting push button pilot does not light up.
Check that the voltage between and
V
in the audio
unit is 12 Vac. If the voltage is correct, there may be
something wrong with the audio unit.
You cannot hear any telephones from the entrance
panel.
Check connections 2 and 3 from the audio unit to all the
telephones. Check the volume control on the panel and
the lighting push button pilot. Make certain that connectors
17 and 18 on the panels are connected up (Multiple-
access installations). If you cannot find the fault, there may
be something wrong with the audio unit.

Check that the voltage between the mass and Vac in the
audio unit is 12 Vac. If the voltage is correct, there may
be something wrong with the phonic unit.
You cannot hear any telephones from the entrance
panel.
Check connections 2 and 3 from the phonic unit to all the
telephones. Check the volume control on the panel and
the lighting push button pilot. If you cannot find the fault,

You can hear whistling in the panel. The sound
produces feedback.
Lower the sound level using the volume control on the
audio unit.
The call tone doesn’t ring on any telephone.
Check that the voltage between 2 and 7 in the audio unit,
without pressing the push button, is 9 Vdc. Check the
connection between 7 in the audio unit and the push
buttons. Check connection 2 from the audio unit to the
telephones. If you cannot find the fault, there may be
something wrong with the audio unit.
The call tone doesn’t ring in a telephone.
Check connections 2 and 5 from the telephone to the
entrance panel. Check that the telephone is not off the

Check that the voltage between 1 and 2 in the audio unit,
without pressing the door-openers, is 5 Vdc. Check that
the voltage between 11 and 12 in the audio unit, when
you press the door-openers, is 12 Vac. If you cannot find
the fault, the lock may be broken.
The door-opener doesn't work unless someone
presses a push button
Check that at least one entrance panel has been defined
as the main one. If you cannot find the fault, there may
be something wrong with the audio unit.
You can hear several entrance panels at the same
time on the telephones.
Check that only one panel has been defined as the main
one. Make certain that connectors 17 and 18 on the
panels are connected up. If you cannot find the fault, there
may be something wrong with the audio unit.
When you call one of the panels the rest of the
panels in the system are not deactivated.
Make certain that connectors 17 and 18 on the panels
are connected up. Check that the voltage between 2 and
17 in each one of the audio unit is 8 Vdc when you press
the push button on one of the panels. If you cannot find
the fault, there may be something wrong with the audio
units.
