I just installed this detector and it makes a very soft chirping noise roughly every 15 seconds. It's nowhere near as loud as the test alarm. Why?


Thank you for your question, Heather. We apologize for the inconvenience. A number of things could be causing the chirping, like low battery. Please don’t hesitate to reach out to us at First Alert at 1 (800)-323-9005 so that we can get to a resolution for you.
