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 Instructions”.
To program the connection brackets/telephones, make sure that you are in
the main entrance panel. Before keying the monitor/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 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 audo unit is lit. Make sure that the voltage
between – and + of the power supply unit is 15 Vdc. Check if there are
any short circuits and, if so, fix them. Disconnect the power supply unit
from the mains 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 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 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 that the voltage between – and + of the keypad is 15 Vdc. Check
the – and + connections from the keypad to the power supply unit. If no
fault is detected, there may be something wrong with the 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 Vdc. Check the
– and + connections from the audio unit to the power supply unit. Check
the connection between the keypad and the audio unit.
In the display appear "88888"
Ensure that the voltage between – and + of the audio unit is 15 Vdc. If
the voltage is correct, there may be something wrong with the audio unit.
The text “F0” flashes in the display
Check if there is a short circuit in the connections from the audio unit to
the monitors/telephones, D1 and D2. If no fault is detected, 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.
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
monitor/telephone is in the ON position (on the left). Check the connections
D1 and D2 from the audio unit to the monitors/telephones and the
connections D2 and D3 between panels (installations with several points
of entry). Check connections D4 and D5 between panels (installations on
estates). If no fault is detected, there may be something wrong with the
monitor/telephone or with the audio unit.
DIGITAL
DOOR ENTRY SYSTEMS
No monitor/telephone can be heard from the entrance panel
One monitor/telephone cannot be heard from the entrance panel
You cannot hear the entrance panel on any monitor/telephone
You cannot hear the entrance panel on one monitor/telephone
The sound produces feedback
The electric lock does not work
In an installation with several points of entry you are unable to call from one
of them.
In installations with several points of entry, calling on one of the entrance
panels does not deactivate the other panels of the system
The video system does not work in any monitor: auto switch-on, screen
doesn´t come on when receiving a call,..
Video system does not work in one monitor: auto switch-on, screen doesn´t
come on when receiving a call,..
Poor image quality on all the monitors: distorted picture, ghost images,
loss of synchronisation.
Check the volume control on the panel. If you cannot find the fault, there
may be something wrong with the audio unit.
Check connections D1 and D2 from the monitor/telephone to the audio
unit. If you cannot find the fault, there may be something wrong with the
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.
Check connections D1 and D2 from the monitor/telephone to the audio
unit. If you cannot find the fault, there may be something wrong with the
monitor/telephone.
Lower the sound level using the volume controls on the audio unit.
Check the connections of the keypad. Check that when the electric lock
button is pressed, the voltage between 11 and 12 of the keypad is 15
Vdc. If you cannot find the fault, there may be something wrong with the
electric lock.
Verify that you can call the telephones/monitors independently (connect
D1, D2 of one panel to the telephones/monitors and disconnect D3, D2
from the other panels). If you can establish communication in this way,
you must adjust the power supply level of the audio units (please contact
the manufacturer). If it is not possible to establish independent
communication, there may be a problem with the audio unit or the keypad.
Check connections D2 and D3 between the different panels of the system.
If you cannot find the fault, there may be something wrong with the audio
unit.
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 the - conexion between the power supply and the audio unit. 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.
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.
Check the polarity of the twisted pair.
In multiple access installation, check that you have only one entrance
