I think it is usually 8 or 6 core unscreened for standard alarms (you can
get 2 and 4 core as well)  AFAIK the screened is required by Comfort
Keypads/Video. IME it is pretty hard to get hold of and definitely isn't a
stock item.

Cheers
Mick

I didnt receive it either ..so i think yahoo is playing up again....

I believe 8 core screened is used for alarm systems in the UK is that
correct ? Is is to meet British standards or just recommende by the alarm
suppliers..Never seen screened cable used over here as yet.......

PS......Thinking of putting C_Bus in Mick ???

a highly inductive load which would induce noise into your lv
cables.....and so long as they are not long parallel runs..
