I have a smoke alarm that you can buy a relay expansion board for. I can't remember the part number but did get it from TLC.

depends how many you need but, if it's more than a few, having simple sensors & a central control box could be a good / economical way to go - with an optional relay-out board fitted in the box to provide info' via digital inputs to Cortex ...
that's what we've done, anyway - so Cortex knows where the problem is, and can assist accordingly ...
Mind if I ask how much your system cost? I was looking at doing this and couldn't seem to get a figure below 4 figures, which for my size of house seemed excessive.Quote:

Ah! I should have known to check TLC.....used them for so many other of my supplies.
