Kidde PE9 (P9050) Battery-Operated Photoelectric Sensor Smoke Alarm

Did u check ur smoke alarm lately, One out of 5 started beeping, thought I needed a battery but my alarm was shorting out, so long story short if ur alarm is over 10 yrs get a new one like this , easy to install and lasted over 10 yrs

I bought 3 of these for our house in November 2022 and installed them immediately. Starting in January, one had issues with occasional false alarms. It got worse the next month. In this case, changing batteries and blowing out the alarm to clear dust (since the alarm is photosensitive) didn't help. I contacted Kidde and they replaced it quickly for free. They did ask for me to ship back the defective unit but shipping was paid for by them. Thanks Kidde!

Fairly straightforward install. Haven’t had it in service long enough to know whether it eats batteries or not , but I like the spring-loaded friction-fit battery terminals, as opposed to the old-school snap-tight terminals that lock on so tight, they break off the plastic mount when changing the battery.So far, this photo-electric smoke detector passes monthly test button pushes, and no false alarms.Heating with wood, I mounted it next to the 35 year-old ionizing smoke detector, and added a sensitive carbon monoxide monitor to cover all contingencies.

Well it does not go off because of steam from the bathroom anymore that is wonderful. But it woke me up at 4 am with a dead battery already. I don’t think that’s normal. I have had several smoke detectors and none went dead this quick. Trying a new battery and hopefully it’s not the same outcome.

These Kidde smoke detectors have been unreliable, almost every one we have purchased started going off for no reason at some point and could not be reset. I'm surprised these have not been recalled due to these issues, the original set we purchased from Home Depot and when we took some back for replacement they said it was a common issue with this brand/model. After many false alarms (often in the middle of the night) everyone starts to disregard the alarm and assume it's another defect. Home Depot ultimately replaced all 8 units but 5 of the replacements eventually had the same issued within 2 years. So now I purchased 5 new units from Amazon in May 2019, and already now in July 2019 one of these new units started going off in the middle of the night and would not stay reset.I gave these many chances but have lost all confidence in Kidde.
