Our house had 7 First Alert brand smoke detectors model P1210E. All of them were 10 year detectors with 10 year integrated batteries. All of them were purchased around 2020. So far I’ve had to deactivate 5 of them becasue they were going off randomly at all hours of the day and night. They would beep 3 times a couple times then stop. Or not. I’d finally find the one responsible , deactivate it, and then another one would go off a few weeks later. I’ve repeated this process 5 times. These are not reliable products and now my house is down 5 smoke detectors because of this totally unacceptable product. We were at my parents house and theirs started doing the same thing. My sister happened to be there and reported that the ones at her house do the same thing. These should be recalled.
