Verifique que el cable coaxial hacia monitores sale de las
bornas M y V1 de la telecámara. En instalaciones de múltiple
acceso, revise las conexiones M, V2 del cable coaxial entre
las diferentes telecámaras. Compruebe la conexión entre la
telecámara y el grupo fónico. Si la distribución se realiza a
través de distribuidores, compruebe que la tensión entre – y
+ de los distribuidores sea de 15 Vdc. Verifique las conexiones
del cable coaxial de la telecámara hacia monitores. Verifique
la posición del puente de configuración J1 en los monitores.

OPERATING PROBLEMS

Nothing works.
Check the mains voltage in the power supply unit that
feeds the audio unit. Check that the voltage between
and V of the power supply is 12 Vac. Check for the
existence of a short circuit and rectify this. Disconnect the
power supply for 1 minute and then reconnect it. If ithe
breakdown continues, 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
supply that feeds the audio unit 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
unit is 12 Vac. If the voltage is correct, there may be
something wrong with the audio unit.
No monitor can be heard from the entrance panel.
Check connections 2 and 3 from the audio unit to all the
monitors. Check the volume control on the panel and the
lighting push button pilot. In multiple access installations,
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.
One monitor cannot be heard from the entrance panel.
Check connections 2 and 3 from the connection bracket
to the audio unit. If you cannot find the fault, there may
be something wrong with the monitor.
You cannot hear an entrance panel on any monitor.
Check connections 2 and 4 from the audio unit to all the
monitors. Check the volume control on the monitors (on
the panel) and the lighting push button pilot. If you cannot
find the fault, there may be something wrong with the
audio unit.
You cannot hear the entrance panel on a monitor.
Check connections 2 and 4 from the connection bracket
to the audio unit. If you cannot find the fault, there may
be something wrong with the monitor.
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 monitor.
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
monitors. If you cannot find the fault, there may be
something wrong with the audio unit.

Si no detecta el fallo, el grupo fónico o la telecámara pueden
estar averiados.

Verifique la posición del puente J1 de configuración del
soporte de conexiones. Revise la conexión entre el soporte
de conexiones y el monitor. Revise las conexiones del coaxial
en el soporte de conexiones del monitor. Revise las conexiones
del cable coaxial desde el soporte de conexiones hacia la
telecámara. Si no encuentra el fallo, el soporte de conexiones
, el derivador o el monitor pueden estar averiados.
The call tone doesn't ring in a monitor.
Check that the handset is not off the hook. Check the
connection between the connection bracket and the monitor.
Check connections 2 and 5 from the conection bracket to
the entrance panel. Check the push-button connection on
the audio unit. If you cannot find the fault, there may be
something wrong with monitor or the panel push-button.
You cannot hear the call confirmation on the entrance panel.
Check that you can hear the monitors on the entrance
panel. Check that the call tone rings on the monitors. If
you cannot find the fault, there may be something wrong
with the audio unit.
The electric lock doesn't work.
Check that the voltage between 1 and 2 in the audio unit,
without pressing the lock release button, is 5 Vdc. Check
that the voltage between 11 and 12 in the audio unit,
when you press the lock release button, is 12 Vac. In
multiple access installations, make certain that connectors
17 and 18 on the panels are connected up. If you cannot
find the fault, the lock may be broken.
In multiple access installation, when you call one of
the panels the rest of the panels in the system are
not disabled.
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.
The video system does not work in any monitor:
auto switch-on, screen doesn´t come on a callis
received,..
Check the mains voltage in the power supply unit that
feeds the monitors. Check that the voltage of the power
supply between - and + is 15 Vdc. Check if there's a short
circuit and rectify it. Disconnect the power supplies supply
for 1 minute and reconnect it. If the breakdown continues,
disconnect all the - and + terminals from the power supply
unit and check that voltage between - and + is 15 Vdc.
If it's not correct, there may be something wrong with the
power supply.
Video system does not work in one monitor: auto
switch-on, screen switching when receiving a call,..
Check that the ON/OFF switch for the video is in ON
position (on the left). Check that the red led of the monitor
is on. Check the connection between the connection bracket
and the monitor. Check that the voltage between - and +
of the connection bracket is 15 Vdc. If failure cannot be
found, there may be something wrong with the monitor.
Poor image quality on all the monitors: distorted
picture, ghost images, loss of synchronisation.
In multiple access installation, check that you have only
one entrance panel defined as the main one.
If splitters have been used in the distribution, check that
the voltage between - and + of the splitters is 15 Vdc.
