Tibs, I did look around on the web, at my usual source anyway, but without knowing all the specifics of your alarm system and cell provider, it's a little tough to say "this will do the trick". But I think this one would probably do the trick IF you're monitoring services uses Ademco format for reporting. They also have a range of other styles depending on carrier and reporting format requirements. You can even get them with voice so it calls you to tell you the alarm went off.

The first set of results I got, when I did a general search, had price tags in the $1000 range which seemed a tad on the high side. Assuming your system is monitored by a company you can ask them what reporting format is used to be sure.
