hello. My name is***** can help you with your question.

If you have more than one of these wired together, you have to replace all the batteries at the same time and then to stop it from chirping, press the test button. However, if you have had these for over 8 years, then they must be replaced. These combination detectors have a limited lifetime of, at the most, 10 years. Of course, if it's nowhere close to that then it would have to be something else, but this is the most common problem. I have the same type throughout my home and when I first found that out I was surprised, but the replacement cost is very low. For most models, in the $10-$12 range. If you let me know what model you have now, I can find it or the equivalent for you.

Hi it looks like Mike opted out, so I can continue if he is still involved. But yes he is absolutely correct with his advice.

You can also check out Home Depot, and Lowes Home Improvement for these as well. They carry them here in NC. They aren't much to buy ;-)

Or if you cant seem to find thm, I will provide a source for that online.
