This is my second New Kidde KN-COPP-B-LP 900-0230 Nighthawk Carbon Monoxide Alarm. They have a finite life of approximately 6 years. I was so pleased with the first one that I owned that I went to eBay to see if there were any for sale. And there were! Highly recommended. Very dependable.

Our detector alerted us to carbon monoxide coming from our oven, perhaps saved us. The alarm will tell you when it’s lifespan is up by beeping - makes the timing of replacement very easy.
