We have moved house & don't want these Simpli-safe modules that you can use to enlarge your system to cover more of the house. There are 5 door/ window modules and a movement sensor. They all work - so if you want to enlarge your system you can adopt them - they are not linked to us.... Thi offer will be complete nonsense to anyone who doesn't have one of these systems & I don't know if any other freeglers have it...
