il problema, è possibile che il monitor sia guasto.
L’accensione automatica non funziona in nessun monitor/citofono
Verificare che il sistema non sia occupato. Verificare che vi sia un solo
posto esterno definito come principale nell’edificio (vedere "Istruzioni di
configurazione della pulsantiera esterna" pagina 18). Nel caso di edifici
multi-accesso, verificare che i posti esterni secondari siano stati numerati
TROUBLE SHOOTING
To program the connection brackets/telephones, make sure that you
are doing so in the main entrance panel of the building (See "Entrance
panel configuration instructions". page 18) and that only one panel
has been defined as the main panel of this building. Check that you
can communicate with the main entrance panel. Do this before entering
the code which you wish to assign to the connection bracket/telephone.
Bear in mind that the entrance panel emits confirmation tones when
the connections bracket or telephone has received the code (if the
equipment is programmed) and shows the message “Equipment
programmed” on the screen. (i.e. when the equipment is programmed).
If you are unable to program the connection brackets/telephones:
Check the connection between the audio unit and the TFT-Keypad
controller.
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 B5, B4, 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 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 B5, B4 or B3, B2 of the
entrance panel to the power supply unit interface. Check the connection
between the audio unit and the TFT-Keypad controller. 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 a call is made
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 shows the message “Impossible to make the call”,
see the next paragraph. If the entrance panel shows the message
“Calling…”, check that the call volume control switch on the
monitor/telephone is not in the lowest position ( ). If no fault is detected,
the monitor/telephone or the pushbutton of the panel may be defective.
The entrance panel shows the message “Impossible to make the call” and
emits beeping tones when a call is attempted.
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,

in modo consecutivo da 1 a 5 (vedere "Istruzioni di configurazione della
pulsantiera esterna" pagina 18). Se non si individua il problema, è
possibile che il gruppo fonico sia guasto.
L’accensione automatica non funziona in un monitor/citofono
Verificare che il sistema non sia. Se non si individua il problema, è
possibile che il supporto di collegamento o il monitor siano guasti.
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 audio unit may be defective.
If the voltage is correct, check the connections of the electric lock. If no
fault is detected, the electric lock may be defective.
In an installation with several points of entry, making a call from one of
the panels does not disable the other panels of the system
Check connections B3, B2 between the different panels of the system. If
the problem arises from the external entrance panels, check the connections
B5, B4 between the different panels of the system.
If no fault is detected, the audio unit 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 camera and the audio unit. In colour
systems, check that when a call is made, the LEDs of the camera light up.
If no fault is detected, the camera 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 that the video ON/OFF switch on the monitor is set to the ON
position. Check that the red LED on the monitor is lit up. Check the
connection between the monitor and the connection bracket. If there are
several monitors in the same dwelling, see “Installation of several monitors
in the same dwelling”. If no fault is detected, the monitor may be defective.
Automatic switch-on does not work on any monitor/telephone
Check that the system is not engaged. Check that only one entrance panel
has been defined as the main panel of the building (See "Entrance panel
configuration instructions". page 18). If there are several points of entry,
check that the secondary panels have been numbered consecutively from
1 to 5 (See "Entrance panel configuration instructions". page 18). If no
fault is detected, the audio unit may be defective.
Automatic switch-on does not work on one monitor/telephone
Check that the system is not engaged. If no fault is detected, the connection
bracket or the monitor may be defective.
