RE: Cable for Smoke Detectors

["Neil Ball" <neilball@xxxxxxxxxxxxxxx>]

Most mains powered/linked alarms are usually wired in series and
simply
require a live & neutral feed to the first detector and then 3-core
(live,
neutral and link/signal) to the other detectors.

It sounds like mains voltage sensors though to me. Not sure how these are
wired though. As said before, these aren't designed to be used with an
alarm
system but used stand-alone I think.
