carbon monoxide detectors first alert image
Stephen T
We have a brand new First Alert smoke/carbon monoxide detector. One day it was going off when I came home for lunch. I called the fire dept. and they came and did a test and said my levels were normal for the basement. A few weeks ago it started going off again so I opened a window. We felt no symptoms. This morning it went off yet again.
Is my device faulty? What could be the problems. Every time it has gone off I have replaced the batteries just in case the signal meant low battery.
Answer
I would try a different unit (or even different brand) and see if the results are the same. You might even try getting separate smoke/CO detectors and try different locations. And if it goes off again, I would have the fire department come and check more than the basement (and they should use two detectors to make sure THEIR readings are accurate). There's a whole myriad of factors involved here; I wouldn't rest until I was sure I wasn't in any danger. People die from CO poisoning every day. I've found a couple of websites that might help:

Why is my smoke detector still blinking green after replacing battery?

It is First Alert carbon monoxide detector and is hard wired with back up batteries. The light goes green for 2 seconds and off 2 seconds. We replaced battery with brand new ones and tested it. It stays green and then starts to blink again.
Answer
Mine chirps too when the battery is low and it will still chirp after you replace that battery. You have to hold the test button and let it beep a few times. Then the light will blink every 30 seconds to let you know it active.
