TROUBLE SHOOTING

Ensure that the entrance panels of the installation are correctly configured.
To do so, check that the values selected in the different positions of the
configuration menu are the same as those shown in the section entitled
“Configuration of the entrance panel according the installation”, page 26.
To program the connection brackets/telephones, make sure that you are in
the main entrance panel and that you have only one entrance panel defined
as the main one. Before keying the connection brackets/telephone code into
the main entrance panel, check that you have communication with the panel.
Remember that the audio unit emits confirmation tones when the connection
bracket/telephone has received the code (programmed connection
bracket/telephone). If you are unable to program the connection/telephone:
check the connection between the numeric keypad and the audio unit.
Nothing works
Check the mains voltage in the power supply units. Ensure that the green
led of the power supply to the audIo unit is lit. Make sure that the voltage
between + and – of the power supply unit is 15 ± 10% Vdc. Check if
there are any short circuits and, if so, fix them. Disconnect the power
supply unit of the keypad for 1 minute and then reconnect it. If the problem
persists, disconnect all the + and – terminals from the power supply unit
and check that the voltage between + and – is 15 ± 10% Vdc. If it is not,
there may be something wrong with the power supply unit.
The cardholders of the entrance panel with directory do not light up
Make sure that the voltage between + and – of the power supply unit is
15 ± 10% Vdc. Check the + and – connections of the entrance panel with
directory to the audio unit. If no fault is detected, there may be something
wrong with the panel with directory.
There is no audio confirmation that a key has been pressed
Check the volume control of the volume of the beep. Check that the voltage
between + and – of the keypad is 15 ± 10% Vdc. Check the + and –
connections from the numeric keypad to the power supply unit. If no fault
is detected, there may be something wrong with the numeric keypad.
In the display the key which has been pressed does not appear
Check if there is audio confirmation that a key has been pressed. Check
that the voltage between + and – of the audio unit is 15 ± 10% Vdc.
Check the + and – connections from the audio unit to the power supply
unit. Check the connection between the numeric keypad and the audio
unit.
The text “F0” flashes in the display
Check wether there is a short-circuit in the connections from the audio
unit to all the devices, D1, D2 or in the connections between the different
entrance panels of the system, D3, D2 and D5, D4. Ensure that the other
panels connected to the BUS have the correct power supply. If you cannot
find the fault, there may be something wrong with the audio unit.

The text “F1” flashes in the display
Check the connection between the numerical keypad and the audio unit.
If no fault is detected, there may be something wrong with the numerical
keypad or the audio unit.
The text “F2” flashes in the display
Ensure that position 1 of the configuration menu of the entrance panel
contains a value that is possible for the particular model of entrance
panel being used. If you cannot find the fault, there may be something
wrong with the audio unit.
If the entrance panel emits intermittent tones when a call is made
The call tone cannot be heard on the monitor/telephone: Check that the
handset is not off the hook. Check that the programming switch of the
device is in ON position (on the left). Check connections D1 and D2 from
the audio unit to all the devices and connections D3 and D2 between the
different entrance panels of the system (installations with several points
of access. If you cannot find the fault, there may be something wrong
with the monitor/telephone or the audio unit.
No monitor/telephone can be heard from the entrance panel
Check the volume control on the panel. If you cannot find the fault, there
may be something wrong with the audio unit.
One monitor/telephone cannot be heard from the entrance panel
Check the cable connections between the receiver and the base of the
monitor/telephone. If you cannot find the fault, there may be something
wrong with the monitor/telephone.
You cannot hear the entrance panel on any monitor/telephone
Check the volume control on the monitors/telephones on the entrance
panel. If you cannot find the fault, there may be something wrong with
the audio unit.
You cannot hear the entrance panel on one monitor/telephone
Check the cable connections between the receiver and the base of the
monitor/telephone. If you cannot find the fault, there may be something
wrong with the monitor/telephone.
The sound produces feedback
Adjust the feedback control of the audio unit (see step 8 on page 23). If
the feedback persists, lower the volume using the volume controls of the
audio unit.
The electric lock does not work
Check the connections of the electric lock. Check that when the electric
lock button is pressed, the voltage between 11 and 12 of the keypad is
15 ± 10% Vdc. If you cannot find the fault, there may be something
wrong with the electric lock.
In installations with multiple points of entry, calling on one of the entrance
panels does not deactivate the other panels of the system
Check connections D3 and D2 between the different panels of the system.
If you cannot find the fault, there may be something wrong with the audio
unit.
The video system does not work in any monitor: auto switch-on, screen
doesn´t come on when receiving a call,..
Check the mains voltage in the power supply unit that feeds the monitors.
Check that the voltage of the power supplies between + and – is 15 ±
