Dr Gary,
The Prevost already comes with an alarm system. They're a bit different over the years and since you didn't specify your coach details, it's hard to help much more.
Please edit your profile and edit your signature to include your coach year, finisher, model, etc. There's several posts on how to do this, just search.
