## Description

no

Review: 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!

## 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.
