Remedy for Persistent Bleeping Smoke Alarm

Smoke and AlarmMy smoke alarm was set off when there was a lot of dust during a DIY job. It wouldn't stop bleeping when I decided to replace the battery on completing the DIY. I just found the solution; there was still some dust in the sensor vent so I blew into it vigorously and replaced the battery. Voila, it worked perfectly.

Simple Three Part Solution:

a. Dust out all dust and debris from the metal battery connectors within alarm.

b. A New battery (square 9 volt) is properly placed with Positive Matching Positive (+) & Negative Matching Negative (-) and the little plastic hatch within is closed up with a click.

c. Finally, and MOST IMPORTANTLY - Flip the corresponding circuit breaker for a quick reset.

The chirping of the evil birds will now stop and never return...until you do something else stupid, that is. :) Cheers!

You should also check every battery in all detectors if they are plugged in to the house wiring. I had "the Beep" until I unhooked one completely from the house wiring and the battery. THEN another one started beeping, again unhooked it completely.


Then a third one in an unused bedroom. Changed that battery, remembering I had never done that in over two years, beeping stopped. Hooked first two back up to house wiring and new battery. Beeping stopped.

I want to hug you and kiss you for giving us the answer we needed. After removing &replacing 9volt batteries in all 7 wired smoke detectors and then disconnected all 7 from ceiling and removed all batteries from said units, we were at a loss! How can this continue to beep? When all else failed I Googled the question and immediately tried your suggestion. It was the doggone carbon dioxide detector that we too forgot all about ! Thank you and God Bless you.
