Nothing works
Check whether the LED of the power supply unit is unlit.
With LED unlit: a) check the mains voltage, b) disconnect terminals
+,
of the power supply unit and check the voltage in the terminals.
If no voltage is detected in these terminals, the power supply unit
may be defective. If a voltage is detected, check that there is no
short circuit in the connections
+,
between the devices of the
installation.
With LED lit: check the voltage between terminals
+,
. Disconnect
terminals
+,
of the power supply unit and re-check the voltage
in the terminals.
The card-holders do not light up
Check the voltage in terminals K1, K2 of the audio unit. If no fault
is detected, the audio unit may be defective.
The entrance panel does not emit any sound when a call is
made
Check whether the call rings on the monitors; if it does, see the
following paragraph. Check connection
K1, K2
of the entrance
panel to the monitor. If no fault is detected, the audio unit may be
defective.
The call rings on the monitors 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
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 is not in
position. If no fault is detected, the monitor or the audio unit of
the panel may be defective.
The entrance panel emits beeping tones when a call is made
If the problem occurs with all the monitors, check the connection
K1, K2 of the audio unit to the monitors.
If the call has not rung on the monitor, Make sure that the connection
bracket has been configured correctly, see pages 6 and 7. Make
sure that the distances and type of cable used meet the specifications
given on page 5. If no fault is detected, the connection bracket or
other equipment of the installation may be defective.
No monitor 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.
The entrance panel cannot be heard on any monitor
Check connection 30 between the speaker-microphone module
and the audio unit. Test the setting of the volume control in the
audio unit and in the monitor. If no fault is detected, the speaker-
microphone module may be defective.
Feedback is produced on all the monitors
Adjust the volume controls in the audio unit and in the monitor.
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. 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 audio unit may be defective. If the
voltage is correct, check the connections of the electric lock. Make
sure that the distances and type of cable used meet the specifications
given on page 5. If no fault is detected, the electric lock may be
defective.
The video system does not work on any monitor: automatic
switch-on and normal screen switch-on do not work when a
call is received
Check connection 39 between the video unit and the audio unit.
Check that when a call is made, the LEDs of the video unit light
up. Make sure that the distances and type of cable used meet the
specifications given on page 5.
If no fault is detected, the video
unit or the audio unit may be defective.
The video system does not work on one monitor: automatic
switch-on and normal screen switch-on do not work when a
call is received
Check the connection between the monitor and the connection
bracket. If there are several monitors in the same dwelling, see
Installation of two monitors in parallel. Make sure that the
distances and type of cable used meet the specifications given on
page 5.
If no fault is detected, the monitor may be defective.
Automatic switch-on does not work on any monitor
Check that the system is not engaged. Make sure that the distances
and type of cable used meet the specifications given on page 5.
If no fault is detected, the audio unit may be defective.
Automatic switch-on does not work on one monitor
Check that the system is not engaged. Make sure that the distances
and type of cable used meet the specifications given on page 5.
If no fault is detected, the connection bracket or the monitor may
be defective.
