Review: The ideal Carbon Monoxide Alarm - This is just the ideal Kidde Carbon Monoxide Alarm for me – simple, reliable, and affordable peace of mind. Installation could not have been simpler: plug it into a standard outlet, and you're ready to go. I prefer the slim design greatly; it does not take up the second outlet, so I can still use that area. Why I’m content with it: Easy to set up: No special tools or difficult setup — plug and play. Definitive signals: It features an easy-to-read digital display that can give confidence that it’s working properly. Loud Alarm: It is loud, as I have tried out and is able to wake me up or gain my attention quickly. Trustworthy brand: Kidde is a brand that can be trusted, and this smoke detector is robustly built. All in all, it gives me actual peace of mind that it is protecting my home. I'm likely to buy another soon for upstairs — would highly recommend!
Review: Reliable Detector With One Important Thing to Know - This carbon monoxide detector is simple, compact, and very easy to use. There isn’t much of a display—just an LED indicator—but it still does its job well and gives peace of mind once it’s plugged in. The alert tones are loud enough to hear from another room, which is great for safety. One thing other customers should definitely know: the low-battery/alert chirp sounds exactly like a standard fire alarm. When ours started chirping, we went around the house checking every single smoke detector before realizing it was actually this device. So if you hear a mystery chirp, make sure to check this unit too. Overall, it’s functional, straightforward, and provides solid leak detection. Just keep that identical chirp in mind and you’ll be all set. Highly recommend for an easy layer of home safety.

## Questions & Answers

**Q: What is the location of the wall plug on the device?  Will it cover the entire outlet?**
A: The plug also can be removed from the unit in case you want to mount the device on the wall or stand it on a table or night stand.

**Q: How do you turn on the "low battery hush"?"**
A: Not sure, but my suggestion would be to replace the battery. What good is a battery backup if your battery is low?

**Q: When I unplug this device the green light goes off even though the batteries are installed as a backup. Is that normal?**
A: When plugged into the wall outlet, it'll have a constant green light. When running on battery backup, it'll flash the green light every 60 seconds to indicate that it is still working and it'll flash red when the backup battery is low on power and needs replacing.

**Q: When I try put battery in or plug it in, the alarm goes off! Does that alarm sound stop? It's brand new**
A: My unit kept beeping every minute. The batteries were not put in correctly when I received the unit! The problem seems to have stopped for now.

### ⭐⭐⭐⭐⭐ Great carbon monoxide alarm
*by L***E on July 31, 2025*

This is replacing the last Kidde alarm that I owned, which was identical. It lasted 10 years without changing the battery and was very functional. It is reasonably priced, and I like the protection that it provides. Very easy to install. Just plug it in.
