The Kidde K10LLDCO carbon monoxide (CO) alarm is designed to detect CO for 10 years. It comes with a screen which shows the CO level when there’s a build-up of the killer gas. Indicators show when the alarm is working, faulty and when it has detected CO in the last 14 days, which is useful if you’ve been on holiday. It comes with a built-in battery that should be good for 10 years. And Kidde is so confident about the quality of their alarm that this one comes with a 10-year warranty covering every day of its expected life. But what’s it like at detecting CO? Read on for everything we know about this Kidde CO alarm, including how it fared in our CO detection tests.
