looking at 8 core burglar alarm cables today.

I see i can buy screened or unscreened.

Not much cost difference but why should I need screened cables?

The old alarm system is a mixture of cat 5 and unscreened 6 core

Doesn't matter if its an alarm or not, the screen it to stop the cable picking up "spikes" or other radio waves that may effect what ever is at the other end (Alarm in this case)
Some panels you could wire everything in damp string if you wanted to, so long as the keypad was wired in screened cable it was happy. (Also seen lots that should be screened that are not screened) I wouldn't use it unless it MUST be used.

Happy to help. (never actually tried the damp string though, but the makers did say the panel is not fussy about the circuits, but very fussy about the data)
