Re: Structured approach to cabling

[Raymond <Reb.barnett@xxxxxxx>]

My Comfort system is wired using a mixture of unscreened alarm cable,
and CAT5 UTP (unstranded). The system recommends that keypads that use
shielded because they use a serial data protocol, but I've had no
problems over a length of CAT5 that runs rather close to a gaggle of
mains lighting cables.

My only recommendation is not to use unstranded cable unless you're
linking a long run - it's a particular problem when you come to join up
all the common power cables in Comfort - twisting them together doesn't
work too well, and they snap too easily, plus you can't stuff many wires
into the single power connectors. I've resorted to using a 5amp cable
connector to join all the common wires, then running a pair of cat5
cores the short distance to Comfort's connectors.
