Found out from Firex that some of the issues are actually misunderstandings. If you push the test buttom of a smoke detector or a smoke/co2 it will set off all of the alarms in the house except for itself. So its not actually "bad", its just working the way they've designed it to. I guess then to be sure you have to go to each alarm and push the test button. Probably should do that anyhow, right?
