Cabling Recommendations
Conventional Zones
Cabled in red Twin Plastic Sheath (TPS), Fire rated Radox or approved equivalent.
Analogue Loop
Two core cable. The minimum cable size is 0.75mm
2
, the maximum loop resistance is 50 ohms and
the maximum loop distance is 2km.
RS 485 Network
Single twisted pair screened (2 core) cable originating from FACP extending through the protected
areas and returning to the FACP.
Cable Specifications
Capacitance of 100 Pico farads per metre or less
Resistance of 100 milliohms per metre or less
Impedance of loop typical 100 to 120 ohms
Maximum distances between modules 1.2km providing cable meets above specifications.
Recommended cable type
Belden 8132 or 9842 (non fire rated)
Radox FR Communication 0.75mm 1 pair (fire rated) x 2
SmartTerminal
Single twisted pair shielded cable (2 core) plus 2 core power, or local supply. Maximum distance
between from the last
SmartTerminal
and the FACP is 1.2km.
