Non si sente il posto esterno in un citofono
Esaminare le connessioni del cavo fra il ricevitore e la base del
citofono. Verificare il pulsante di aggancio della base del citofono.
Se non si individua il problema, è possibile che il citofono sia
guasto.
C'è un ritorno del suono in tutti i citofoni
Regolare il regolatori del volume dell'audio nel gruppo fonico. Se
non si individua il problema, è possibile che il modulo altoparlante-
microfono sia guasto.
L'apriporta non funziona
Scollegare nel gruppo fonico i cavi dei morsetti 11, 12 o 11, 12c,
a seconda dei casi. Verificare la tensione fra tali morsetti, creando
un ponticello fra i morsetti 22 e 18. Se non vi è tensione o se la
tensione è inferiore a quella indicata, è possibile che il gruppo
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 7).
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 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 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 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 telephone is not
in the lowest position (put the cancelled speaker symbol). If no
fault is detected, the telephone or the pushbutton of the panel may
be defective.
The entrance panel emits beeping tones when a call is made
If the problem occurs with all the telephones, check the connection
B1, B2 of the power supply unit interface to the telephones.
If the call has not rung on the telephone and if the problem occurs
from all the entrance panels of the installation, make sure that the
fonico sia guasto.
Se la tensione è corretta, esaminare le connessioni dell'apriporta.
Se non si individua il problema, è possibile che l'apriporta sia
guasto.
L'accensione automatica non funziona in nessun citofono
Verificare che il sistema non sia occupato. Verificare che vi sia
un solo posto definito come principale nell'edificio (posizioni dello
switch SW1 del gruppo fonico: disegno con le posizioni del
microswitch 1 verso l'alto e del 2 verso il basso).
Se non si individua il problema, è possibile che il gruppo fonico
sia guasto.
L'accensione automatica non funziona in un citofono
Verificare che il sistema non sia occupato. Se non si individua il
problema, è possibile che il citofono siano guasto.
telephone has been programmed and that the receiver of the
telephone has been hung up. Check that the programming switch
of the 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
telephones. If no fault is detected, the 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 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 telephone cannot be heard at the entrance panel
Check the connections of the cable between the receiver and the
base of the telephone. Check the hang-up pushbutton on the base
of the telephone. If no fault is detected, the 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 telephone. Check the hang-up pushbutton on the base
of the telephone. If no fault is detected, the 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.
Automatic switch-on does not work on any telephone
Check that the system is not engaged. Check that only one entrance
panel has been defined as the main panel of the building (positions
of SW1 switch of the audio unit: see illustration showing microswitch
1 up and microswitch 2 down). If no fault is detected, the audio
unit may be defective.
Automatic switch-on does not work on one telephone
Check that the system is not engaged. If no fault is detected, the
telephone may be defective.
