Cable size and type :
When running cables for any intercom system, these
cables must be installed separately from the mains cables. All multipair
cables should be to CW1308 specification. (0.5mm twisted pair telephone
cable). Max resistance = 10 Ohm.
Lock release wires should be doubled up. Max resistance = 3 Ohm
The cables sizes above can be used for distances up to 50m. On distances
above 50m the cable sizes should be increased to keep the overall resistance
of the cable below the RESISTANCE’S indicated above.
The total length of standard telephone wiring between the primary and each
extension socket must not exceed 50M. The total length from the primary
socket to the furthest secondary socket must not exceed 100M.
Dimensions
The ART280 is enclosed in a standard 9 module DIN box. (157.5mm
