Kidde Hardwired Smoke & Carbon Monoxide Voice Alarm, Interconnectable with AA Battery Backup

We bought 5 five pack unit after a remodel last year. I have had two units fail in the last 18 months! When the units fail, the green light goes out and it emits 3 beeps (usually at 2am) every 10 minutes. Replacing batteries only stops the beeping for a month. I have also changed the location of the failing unit (to exclude environmental issues in that particular room) and the problem follows the unit. If the Kidde Fire extinguishers have a 40% failure rate also, I fear that a small fire may result in the loss of my house as I scramble to find a working extinguisher. I losing confidence that Kidde can keep my family safe.

we purchased our newly built home with 2 Model 900-CUAR detectors installed. the detector in the living room has now gone bad for a second time in less than a year. The hallway unit is yet to give us an issue. Can't say I'm very impressed when I have to keep replacing this unit.

These were installed as new construction about a year ago. They started faulting a few months ago. So, got maybe 7 months out of the promised 10 years. Did ALL the troubleshooting stops perched on a ladder, changed batteries again and again. They'd work a few days and then start up again. Gave up and took them down because it's SAFER to be without than have them keep going off in the bedrooms and halls of my 86-year old parents. My mom tries to climb up and stop them when they go off in the middle on the night.

We moved into new construction house last year, there are 10 detectors in my house,5 out of 10 working now, replace three times, the same issue still happens

one year old and it is already failing. acts like it has a low battery fault, but after resetting several times it starts chirping again after a month or two. Total junk

Faulty. Just like the other reviews, we have one that will beep 3 times every minute for 10 minutes. Changed the battery and a week later, had the same issue. Went off once at 2am and then again at 6am. Unfortunately, it came with our new build home at only 1 year old and not much we can do. Trying to see if we can buy a different one that works without having to change all our other alarms

Bought less than a year ago and already giving false alarms at 3-4 am that wakes up my baby in his room. Changed battery, cleaned, and less than 3 weeks later doing the exact same thing. Not sure what to do at this point as these are not cheap to replace.

Awful product. Faulty. Changed batteries. Cleaned device. Without fail it, status light turns off and will beep 3 times every minute for 10 mins and then the light will come back on. Every. Single. Day. I even disconnected the AC power and it still does it. Worst ever.

I placed 7 Kiddie 900CUAR-V smoke/co detectors. I had to replace 3 of them within 4 months due to middle night false alarms. There must be better systems on the market.

Zero stars. Faulty 3 beeps that will not stop after battery changes, cleaning, reset... poor quality will need to find another brand to use. Do not recommend. Good luck. Stay safe
