Any hardwired motion will work with your system. Depending on if you have animals or if you have a harsher environment than any of the lower end motions will work fine. If you have large dogs or have sunlight shining on the motion sensor or if you have heater ducts in the area then I would recommend one of the more advance Dual Tech motions made by Ademco. These motions have more advanced technology in them to allow for heat and light variances so they aren't always creating false alarms. The DT-7435 and the DT-7450 are good examples.
