Nik,
One
further thought that's just occurred to me - you may want to use stranded
"alarm" cable after all. A bundle of (say) 10x alarm cables is much smaller
than
10x Cat5 - it could be an issue if you're routing a lot of cables to one
place
with limited access.
The
smaller diameter of the alarm cable allowed me to get more cables through a
given number of holes than if I'd used Cat5 instead.
Hope
it's not too late for you,
Tim

(just
my 2p :-) )
It
will go through the walls so it will be Cat5e, that I already ordered. I'll
have
200m left on the reel, so I'll use it for PIR.
Cheers,
Nik
Nik,
Alarm cable is usually stranded to permit
flexing....Cat 5 cable is better quality but not as flexible.. it is
fine for PIR's if the route is fixed and not subject to the cables
being
moved...decorating etc... additionally it is important to check continuity
before alarming the system as the cat 5 can break while being routed (same
happens with stranded, but not so often)....
Using shielded is a waste of money...it is not
needed... for a direct wired contact, which is not affected by
interference...
just my 2p worth

Subject: [ukha_d] Which cable to use
for PIR sensor
I asume that
CAT5, CAT5e, CAT are all fine.
Can someone
confirm please?
Should I go for
shielded one?
Cheers,
