Where you are crossing cables it should be  at 90 degress and spaced about
500mm apart ( i think at least here in aussie) if running parallel with
mains stuff it should be ok so long as its not a highly inductive load
which would induce noise into your lv cables.....and so long as they are
not long parallel runs..

I personally would use security cable for all alarm stuff...but thats just
my personal choice...

First just an accolade for Keith's coloured tape cable marking system, I
can
confirm this works excellently. I actually used a slightly modified version
using more colours of tape but which allows me to identify cables by floor,
room, location within room and then individual cable. The electricians
think
I am crazy but who cares;)

Now to the questions....

I have a number of areas where crossing or close running of cables cannot
be
avoided due to the constraints of the house construction I have tried to
keep it to a minimum but it is still there.

How much attention do I need to give to keeping CT100, CAT5, CAT5 Shielded
and Alarm cables seperate from each other and is it ok to run like cables
in
bundles (eg all speaker cables in a bundle)?

Where cables cross/close run is there any benefit to trying to shield them
using aluminium foil or something similar?

For some of the alarm circuits to windows I can run CAT5 or alarm cable, in
many cases these windows have several openers and I only need one pair per
opener so I am thinking of splitting the cable after it gets to the window.
Would alarm cable or CAT5 stand up best to this treatment? I know it won't
be CAT 5 spec after I split it but I don't intend installing PCs in my
windows;)

About all I can think of for now and I am going to soak my muscles after a
marathon cable pulling session!

Oh and so far 20 Cat 5 cables into the main living room with maybe another
5
to go excluding the windows. Is this enough?

Cheers Mick
