TROUBLE SHOOTING
To program the monitors/telephones, check that you are located on the
main entrance panel (the J1 jumper is fitted to the audio unit) and that
you have only one entrance panel defined as the main one. Make sure
you have communication with the main entrance panel before pressing
the push-button that you want to associate to the connection
bracket/telephone. Remember that the panel emits a confirmation tone
once the monitor/telephone has received the code (device programmed).
If the monitor/telephone cannot be programmed: Check the connection
between 7 in the audio unit and the push-buttons , the connection
between the push-buttons and the concentrator of calls and the connection
between the concentrator of calls
Nothing works.
Check the mains voltage in the power supply unit that feeds the
audio unit. Ensure that the green led of the power supply to the
audIo unit is lit. Check that the voltage between + and – of the
power supply is 15 ±10% Vdc. Check for the existence of a short
circuit and rectify this. If ithe breakdown continues, disconnect all
the power supply + and – terminals, and check that the voltage
between + and – is 15 ±10%Vdc. If you cannot find the fault,
there may be something wrong with the power supply.
The lighting push-button pilot does not light up.
Check that the voltage between + and – in the audio unit is 15
± 10% Vdc. If the voltage is correct, there may be something
wrong with the audio unit.
The card holders do not light up.
Check that the voltage between + and – of the power supply that
supplies the audio unit is 15 ±10% Vdc. Check that the voltage
between 9 and 10 in the audio unit, with the lighting push-button
activated, is 15 ±10% Vdc. Check whether the lamp is burnt out.
You cannot hear any sound on the entrance panel when a call
is made.
Check the connection between 7 in the audio unit and the push-
buttons. Check the connection between the concentrator of calls
and the push-buttons and between the concentrator of calls and
the audio unit. If you cannot find the fault, there may be something
wrong with the concentrator of calls or the audio unit.
When a call is made, the monitors/telephones ring but
confirmation of the call cannot be heard on the entrance panel.
Check the volume control of the entrance panel audio unit. If you
cannot find the fault, there may be something wrong with the
audio unit.
If the red indicator light flash continuosly.
Check wether there is a short-circuit in the connections D1, D2
from the audio unit to all the devices. If required, check connections
D3, D2 and D5, D4 of the equipment in the installation. If you
cannot find the fault, there may be something wrong with the
audio unit.
If intermittent tones can be heard on the entrance panel when
a call is made.
The call tone cannot be heard on the telephone: Check that the
handset is not off the hook. Check that the programming switch
of the device is in ON position. Check connections D1 and D2
from the audio unit to all the devices. If required, check connections
D I G I TA L V I D E O D O O R E N T R Y S Y S T E M S
and the audio unit.
D3, D2 and D5, D4 of the equipment in the installation. If you
cannot find the fault, the telephone, the audio unit or some other
equipment in the installation may have broken down.
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 ande the base
of telephone. Check the hanging-up button on the base of the
monitor/telephone. If you cannot find the fault, there may be
something wrong with the telephone.
You cannot hear the entrance panel on any monitor/telephone.
Check the volume control on the devices (on the panel). If you
cannot find the fault, there may be something wrong with the
audio unit.
You cannot hear the entrance panel on a monitor/telephone.
Check the cable connections between the receiver ande the base
of monitor/telephone. Check the hanging-up button on 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
15). If the feedback persists, lower the volume using the volume
controls of the audio unit.
The electric lock doesn’t work.
Check that the voltage between 11 and 12 in the audio unit is 15
± 10% Vdc, by making a bridge between terminals 22 and 18.
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.
In housing compound installations, making a call from one of
the external entrance panels does not disable the entrance
panels of the building which is being called.
Check connections D3 and D2 from the entrance panel to the
identifying accessories of the building. If the fault cannot be found,
there may be something wrong with the audio unit or the identifying
accessory.
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 supply between +
and – is 15 ± 10% Vdc. Check the + and – conexions 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 ± 10% Vdc. If it's not correct, there
may be something wrong with the power supply.
