The white BUS-SCS cable, item
336904, purposely designed and
produced for the installation of
SCS Video Door Entry Systems
and Sound Systems However, it is
also suitable for use in Automation,
Temperature Control, and Burglar-
Alarm SCS Systems This cable is used
for the distribution of the power
supplies and the operating signals to
all BUS system devices
The cable consists of a white external
cable sheath and two twisted flexible
conductors (section of 0 5 mm
2
), one
brown and one brown/white It is
sold in 200 m coils
It is therefore suitable for use:
„ „ In open air installations, inside
trunking, cable trays, and piping
„ „ Inside walls, using suitable piping
„ „ In the ground, using suitable
piping
uNDERGROuND CABLE
INSTALLATION
The 336904 BUS SCS cable can be
installed underground (protected
using appropriate piping), together
with other signalling cables, provided
the voltage is <50 V
It is strictly forbidden to install the
336904 cable in the same conduit as
power supply cables with voltages
>50 V Failure to comply with the
installation requirements will relieve
BTicino of all responsibilities for the
operation of the system installed
INSTALLATION TOGETHER WITH
OTHER CABLES
Although the construction of the cable
guarantees the necessary electrical
insulation level for installation
together with 450/750 V system
cables, it is however not capable of
guaranteeing immunity from any
electromagnetic disturbances that
may occur when installed in the same
conduits as those used for the power
supply cables
It is therefore strongly recommended
that the BUS/SCS cable and the
power supply cables are installed in
separate piping
