A CAT5 wire has 8 wires, in a couple of places I have two devices connected
to a single CAT5 cable each using different wires. Specifically, at my
front
door I have the door contact (magnetic, 2 wires) and the hall pir (4 wires)
both connected to a single CAT5 cable. In the dining room (others to
follow)
I have embedded an IR receiver inside a PIR. In both cases the singals from
the separate devices are split out at node zero through Krone blocks. In
fact a computer network only uses 4 wires and phone only 3 so they can be
combined too (splitters can be bought off the shelf). Having said all of
this, you should not plan your cable laying to be used in this way as it
leaves no headroom at all. But for those of us who have done the cabling
and
will not be allowed to run more, there are ways of sharing and splitting.
