I am a builder. Smoke detectors must be hardwired with battery backup to meet code. One in living space, one in each sleeping are, one in hall outside sleeping area, at least one on each level of house. Most people end up disconnecting them in my experience. I spoke with Kidde years ago and they recommended using only the photoelectric type as they are less susceptible to moisture. I have used the PE in several homes as well as my own. They still go off periodically. It is often at 2 or 3 am when temperature is low and humidity is high and wind is light. I think there is more condensation then. There is no magic solution to this. I have found that when they go off ( ours are about 16' up) turning on the ceiling fans full blast shuts them up pretty quickly.
