Hi folks, I hope everybody is well. I have a situation where a customer of mine says that one or more of the eight new smoke detectors that I replaced in here home nearly three years ago, go off briefly in the middle of the night. The problem started about a year ago and she says it is like the alarm sound, not the chirp for battery replacement. I told here that the only thing I could do is replace them all over again with another brand. What could cause this to happen? Thanks
