Description
The red SCS-BUS cable has been purposely designed and produced for the installation of
burglar-alarm systems This cable is used for the distribution of the power supplies and
the operating signals to all system devices.
The cable consists of a red external sheath and two twisted exible conductors, with a
section of 0.35 mm
2
, one yellow and one red.
The cable has 300/500 V insulation. Using the clear clamp protections included in all the
devices, the systems can also be installed in the same boxes and conduits as the power
lines (110 Vac, 127 Vac and 230 Vac).
WARNING
Although the construction of the cable ensures 300/500 V category electric insulation,
correct system operation is not guaranteed in the following cases, when installed
together with the power cables:
• in industrial environments;
• in residential/service sector environments, when the power cables provide power
supply to one of the following:
• lifts
• inverter
• pumps
• motors and controlled motors
• metal iodines lamps.
The SCS-BUS cable is not suitable for underground installation.
