Troubleshooting - Alcad PDK-41500 Mode D'emploi

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”, see page
25.
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. 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 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 ± 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 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.
In the display appear "88888"
Ensure that the voltage between – and + of the audio unit is 15 ± 10%
Vdc. If the voltage is correct, there may be something wrong with 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 and D2 or in the connections between the
different entrance panels of the system, D2 and D3 (installations with
several points of access). If you cannot find the fault, there may be
something wrong with the audio unit.
DIGITAL DOOR ENTRY SYSTEMS
The text “F1” flashes in the display
If the entrance panel emits intermittent tones when a call is made
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
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 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 D2 and D3 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.
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 numeric 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 monitors/telephones independently (connect
D1, D2 of one panel to the monitors/telephones 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.
