What Customers Are Saying
The product has significant reliability and performance issues. Many customers report the smoke/CO alarms failing prematurely, often within 3-5 years despite the claimed 10-year lifespan. The alarms frequently malfunction, randomly beeping or going off without cause, and some fail to detect actual smoke or fire. Customers describe a frustrating user experience, with the troubleshooting process being ineffective. Some also had trouble interconnecting multiple units as advertised. Overall, the product does not meet basic safety and performance expectations.
Customer review summary generated by AI, including incentivized reviews.It only lasted 3 years.
Would Not RecommendIt only lasted 3 years. I followed the troubleshooting guide and did the rest but it didn't work. The guide says it needs to be replaced. Very disappointing.

Lasted 16 months then failed
Would Not RecommendFailed after 16 months. Alarm sounded. Reset the area and attempted a test. It gave a low battery beep. Replaced the batteries with standard (new) and rechargable. Still got the low battery indication. Toss the alarm in the trash.
From Kidde
Even more frustration, disappointment
Would Not RecommendLike the previous reviewer, after hearing the low battery chirping (less than 2 months after installation) I too replaced with fresh E91 AA batteries according to instructions. Then hit the reset button. Then tried several times to make sure I had the polarity correct. However, even after all that--now I can't get any sound out of this unit whatsoever. Wish I'd read the reviews here before buying. This is is straight-up junk, no KIDDE-ing.

Carbon monoxide alarm won’t stop
I bought and installed 6 of these kidde combined alarms 2 years ago when I moved into my new home. Tonight the carbon monoxide alarm has gone off (with no source and the other non-kidde brand alarms are not going off) in an alarm and won’t stop even when we change batteries. Help!

Unreliable garbage
Would Not RecommendOur house was bought brand new with this kidde system installed and after 3 years 2 smoke alarms and a smoke carbon monoxide alarm have all failed. After replacing battery with approved battery made by kidde they still have low battery alarms going off. I’m never buying a kidde product and will warn everyone I meet to avoid this overpriced unreliable garbage. Oh and the one time there was smoke in our house from something in the kitchen burning the alarms didn’t sound. They only alarm when they ...

Tough Way To Learn A Detector Battery Is Dead...
Would RecommendEarly this morning (4:40am CDT) our fire alarms started going off. The message was that their was both fire and carbon monoxide. We couldn't get them to shut off. I had replaced the batteries in all the detectors back in May of this year. Well - I missed one detector. Because the battery was low - it triggered an alarm. We couldn't get the alarm to stop, so we called the fire department - painful! This is a TERRIBLE way to find out a battery is dead. I would recommend that product enhancement th...

Piece of Garbage
Would Not RecommendAVOID THESE PRODUCTS!!! Unit started chirping incessantly. So I replace the batteries… Easy, right? Nope. Spent literally hours working on this piece of trash. Tried multiple batteries, resetting it, turning the breakers off and on. Everything the manual suggested. Nothing. Still chirping and keeping us awake. I’ve used several brands of smoke detectors in the past with zero issues. Every other brand you just pop out the old batteries and replace them. Not with these. The manual will h...

Saved my family but 2 others have malfunctioned
Would RecommendHad carbon monoxide in my home, one alarm went off, but it was in the basement and we couldn't/didn't hear it. I was on the 2nd floor going to sleep for work but got up and went downstairs because I forgot my phone charger. I shut the TV off thinking my kids went to their rooms and left it on and I faintly heard the alarm going off in the basement, but wasn't sure what it was cause it was pretty faint. I then found my kids passed out on the kitchen floor. When I couldn't wake my kids, I realized...

Be careful
Would Not RecommendThis detector is marketed as a smoke detector although it uses ionization technology that is more suited for fast flaming fires and should be correctly identified as a fire detector. Smoke detectors are more clearly identified as photoelectric and are better at detecting smoke. Kidde is a great company who make excellent products… the package and device should identify the technology being used.
From Kidde
Leading authorities recommend that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types o...

Frustrating, disappointed
Would Not RecommendInstalled March 2017. Nov 2021, "low battery" sounded. I replaced with fresh AA batteries according to instructions. Then reset button. Tried several times to make sure I had the polarity correct and even tested batteries to make sure they were charged. However, unit continues to sound the low battery alert. On top of all that, the unit sliding door was difficult to slide out and the polarity indicators are hard to find and read. I'm just going to remove the whole unit. Rating: "meh". Worked (I ...
