Fire Resistant RS485 Databus Cables
Fire Resistant RS485 Databus Cables
APPLICATION
The cables are designed for RS485 data connections where continued functionality is required
during a fire situation. This cable combines low capacitance insulation with one of the highest levels
of screening to provide high speed, interference free, data transmission where continued functionality
is required during a fire situation.

CABLE CONSTRUCTION
Multipair RS 485 Overall Screened Databus Cable
Conductors: tinned copper wire, stranded according to IEC(EN) 60228 class 2.
ADDISON 115
ADDISON
Insulation: mica glass tape wrapped with PE or PE wrapped with silicone rubber insulation.
Cabling Elements: Insulated cores are twisted to form pairs with varying lay length to minimize
crosstalk. Two pair cable had four cores laid in quad formation.
Cabling: Pairs are cabled together in concentric layers.
Overall screen: Aluminum/polyester tape with tinned copper drain wire.
Outer Sheath: Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1 (Thermosetting LSZH
compound type SW2-SW4 as per BS 7655-2.6 can be offered.)
