MAINTENANCE
The outdoor panels must be kept away from corrosive substances, paints or mechanical shocks.
The terminals must be kept away from water, or any other liquids, mechanical shocks,
fumes, dusts etc. The components of the system can be cleaned with a piece of soft, cotton
cloth.
The optional battery connected with the central unit will be replaced after the expiry of its life
span. The central unit ensures the battery's charging, as long as the battery is not defect. The
state of the battery is indicated by the signals of the LED S3 in RED / GREEN.

WARRANTY
A three year warranty is granted, from the purchase date, on the basis of the proof of purchase
and if the system was used according to the technical manual.
NO WARRANTY IS GRANTED for: inappropriate installation and use, deliberate
damaging, theft, fire, natural disasters, unauthorized interventions to the system,
the lack of protection of the system's components in case of renovation activities
in the building.
The BELLCOME systems for residential buildings are produced in compliance with the EU standards
and bear the CE conformity marking.
The GND connections are not OK
(not tight enough).

UTP cat5e (AWG24), which is
PROG
recommended for installation.
S1 green
Short circuit between +Uv and
S2 red
S3
GNV and/ or GND.

S2 green
- The cable used is different from

Check the GND connections of VPT,
SCU and VTT. Firmly tighten the
wires in the connector.
The wires remained free, including the
shield wire, will be connected only to
the GND connector of SCU
(2 wires in GND).
Check the connections +Uv and
GNV/ GND and correct any errors.
The Vin/ Vout or GNV connection is
interrupted in one connector (VPT, SCU,
or VTT). Check and correct any errors.
The video camera is defect.
VPA must be replaced.
Check Vin/ Vout and GNV
everywhere in the system and
correct any errors.
Remove VTT from the wall,
but keep it connected to
the system. With a PH 0
screwdriver trimmer adjusts the
impedance trimmer (2) from the back
until you get a better image.
We recommend the installation
of a video amplifier (DVA) before or
after SCU in order to amplify the
attenuated video signal and
increase the voltage on +14V
and +Uv connections.
