TROUBLE SHOOTING
To program the connection brackets/telephones, make sure that you
are doing so in the main entrance panel of the building and that only
one panel has been defined as the main panel of this building. Check
that you have communication with the main entrance panel, before
pressing the pushbutton you wish to associate to the connection
bracket/telephone. Remember that the entrance panel emits confirmation
tones when the connection bracket/telephone has received the code
(i.e. when the equipment is programmed). If you are unable to program
the connection brackets/telephones, check the connection between the
pushbuttons and the audio unit and between the pushbutton units.
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 B5, B4, 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 Lighting of the
card-holders, page 13).
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 monitors/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 the problem arises from the external entrance panel, check that
microswitch 3 of the SW1 switch is set to the lower position.
If no fault is detected, the audio unit may be defective.
The call rings on the monitors/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 monitor/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 monitor/telephone
is not in the lowest position
monitor/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 monitors/telephones, check the
connection B1, B2 of the power supply unit interface to the
monitors/telephones.
If the call has not rung on the monitor/telephone and if the problem
occurs from all the entrance panels of the installation, make sure
that the connection bracket/telephone has been programmed and
that the receiver of the monitor/telephone has been hung up.
Check that the programming switch of the connection
bracket/telephone is set to the ON position. Re-check connection
B3, B2 of the audio unit to the power supply unit interface and
2 - W I R E
. If no fault is detected, the
D O O R
E N T R Y
S Y S T E M S
connection B1, B2 of the power supply unit interface to the
monitors/telephones. If no fault is detected, the connection
bracket/telephone or other equipment of the installation may be
defective.
If the problem arises from the external entrance panel, check that
the entrance panel is configured as external (i.e. with microswitch
2 of the SW1 switch set to the upper position) and that the
pushbuttons of the panel have been assigned to the different
buildings. Check the connection B4, B5 between the devices of
the installation.
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 monitor/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 monitor/telephone cannot be heard at the entrance panel
Check the connections of the cable between the receiver and the
base of the monitor/telephone. Check the hang-up pushbutton on
the base of the monitor/telephone. If no fault is detected, the
monitor/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 monitor/telephone. Check the hang-up pushbutton on
the base of the monitor/telephone. If no fault is detected, the
monitor/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.
In an installation with several points of entry, making a call
from one of the panels does not disable the other panels of
the system
Check connections B3, B2 between the different panels of the
system.
If the problem arises from the external entrance panels, check the
connections B5, B4 between the different panels of the system.
If no fault is detected, the audio unit may be defective.
The video system does not work on any monitor: automatic
switch-on and normal screen switch-on do not work when a
call is received
Check connection 39 between the camera and the audio unit. In
colour systems, check that when a call is made, the LEDs of the
camera light up. If no fault is detected, the camera or the audio
unit may be defective.
The video system does not work on one monitor: automatic
switch-on and normal screen switch-on do not work when a
call is received
Check that the video ON/OFF switch on the monitor is set to the
ON position. Check that the red LED on the monitor is lit up. Check
the connection between the monitor and the connection bracket.
If there are several monitors in the same dwelling, see Installation
of several monitors in the same dwelling. If no fault is detected,
the monitor may be defective.
