TROUBLE SHOOTING

Nothing works
Check whether the LED of the power supply unit interface is unlit.
With LED unlit: a) check the mains voltage, b) disconnect terminals
B3, B2 and B1, B2 of the power supply unit interface and check
the voltage in the terminals. If no voltage is detected in these
terminals, the power supply unit interface may be defective. If a
voltage is detected, check that there is no short circuit in the
connections B3, B2 or B1, B2 between the devices of the installation.
With LED lit: check the voltage between terminals B3, B2 and B1,
B2. Disconnect terminals B3, B2 and B1, B2 of the power supply
unit interface and re-check the voltage in the terminals.
If no fault is detected, the power supply unit interface or the audio
unit may be defective.
The pilot of the lighting pushbutton does not light up
Check connection 30 between the speaker-microphone module
and the audio unit. If no fault is detected, the speaker-microphone
module may be defective.
The card-holders do not light up
Configure the lighting in continuous mode (see "How to connect
the audio unit to the pushbutton panel", page 11).
If the card-holders remain unlit, check the connection of the
pushbuttons with the audio unit. If no fault is detected, the audio
unit may be defective.
If the card-holders light up, check connection 30 between the
speaker-microphone module and the audio unit. If no fault is
detected, the speaker-microphone module may be defective.
The entrance panel does not emit any sound when a call is
made
Check whether the call rings on the monitors/telephones; if it
does, see the following paragraph. Check connection B3, B2 of
the entrance panel to the power supply unit interface. Check the
connection of the pushbuttons with the audio unit. If no fault is
detected, the audio unit may be defective.
The call rings on the monitors/telephones but the entrance
panel does not emit any sound when the call pushbutton is
pressed
Check connection 30 between the speaker-microphone module
and the audio unit. Check the adjustment of the volume control
in the entrance panel. If no fault is detected, the audio unit may
be defective.
The call does not ring on a monitor/telephone
If the entrance panel emits beeping tones, see the following
paragraph. If the call confirmation is heard at the entrance panel,
check that the call volume control switch on the monitor/telephone
is not in the lowest position (put the cancelled speaker symbol).
If no fault is detected, the monitor/telephone or the pushbutton
of the panel may be defective.
O sistema de vídeo não funciona num dos monitores: ligação
automática, ligação do ecrã ao receber a chamada
A ligação automática não funciona em nenhum monitor/telefone
A ligação automática não funciona num dos monitores/telefones
The entrance panel emits beeping tones when a call is made
If the problem occurs with all the monitors/telephones, check the
connection B1, B2 of the power supply unit interface to the
monitors/telephones.
If the call has not rung on the monitor/telephone and if the problem
occurs from all the entrance panels of the installation, make sure
that the connection bracket/telephone has been programmed and
that the receiver of the monitor/telephone has been hung up.
Check that the programming switch of the connection
bracket/telephone is set to the ON position. Re-check connection
B3, B2 of the audio unit to the power supply unit interface and
connection B1, B2 of the power supply unit interface to the
monitors/telephones. If no fault is detected, the connection
bracket/telephone or other equipment of the installation may be
defective.
If the problem occurs from only one of the entrance panels of the
installation, check the connection of this panel with the other
panels. If no fault is detected, the audio unit of this panel may be
defective.
No monitor/telephone can be heard at the entrance panel
Check connection 30 between the speaker-microphone module
and the audio unit. Check the setting of the volume control in the
audio unit. If no fault is detected, the speaker-microphone module
may be defective.
One monitor/telephone cannot be heard at the entrance panel
Check the connections of the cable between the receiver and the
base of the monitor/telephone. Check the hang-up pushbutton
on the base of the monitor/telephone. If no fault is detected, the
monitor/telephone may be defective.
The entrance panel cannot be heard on any telephone
Check connection 30 between the speaker-microphone module
and the audio unit. Check the setting of the volume control in the
audio unit. If no fault is detected, the speaker-microphone module
may be defective.
The entrance panel cannot be heard on one telephone
Check the connections of the cable between the receiver and the
base of the monitor/telephone. Check the hang-up pushbutton
on the base of the monitor/telephone. If no fault is detected, the
monitor/telephone may be defective.
Feedback is produced on all the telephones
Check the volume controls in the audio unit. If no fault is detected,
the speaker-microphone module may be defective.
The electric lock does not work
In the audio unit, disconnect the wires of terminals 11, 12 or 11,
12c, as applicable to your case. Check the voltage between these
terminals, making a bridge between terminals 22 and 18. If there
is no voltage or if the voltage is lower than that specified, the
