Title: Kidde i12040 replacements false alarms
Review: Like many reviewers, we replaced old Kidde 1275s giving false alarms, with new Kidde i12040s since they were easy to install in the existing wiring. After about a year, one of the new units started with false alarms. Same time (3am), same room (bedroom). It's entirely possible there is some weird atmospheric condition in the room causing the false alarms. How are you supposed to figure that out? For now, the offending unit is disconnected. It's a small house with several other units that (so far) have not caused any trouble other than join the problem unit in the false alarm. If the others start creating false alarms, we'll replace the entire system with another brand.
