I realize smoke detectors are important to wake us up in case of a fire, but invariably, smoke detector beeping, sometimes called chirping, starts around two in the morning, and always in one of your bedrooms. The other night as I peacefully lay in bed dreaming of chirping birds, suddenly realized it was not a dream. Instead, the smoke detector in my kids’ bedroom decided it was time to die. Why they always seem to die at night, and in your kid’s room no less, is beyond me, but as a mother I wish the smoke detector gods would stop messing with us sleep-deprived mothers.
The next day we put in a new battery, thinking it would solve the smoke detector beeping, but to our dismay the smoke alarm started to chirp again! We tried another battery, but with the same result. I called up the fire department, and a nice fireman told me some things I could try. They worked! The smoke detector beeping stopped and it saved me the time and money of purchasing a new smoke alarm. Check out my steps below!
Try These Steps When Your Smoke Detector Beeping Starts
Before you go out and buy a new smoke alarm try these steps first.
1. Replace the old battery, making sure you insert it correctly. See if the smoke detector beeping stops with simple battery replacement.
2. If the smoke detector beeping continues despite replacing the battery, remove the smoke alarm from the ceiling. This is usually done by rotation of the detector until it releases from the base. If the smoke detector is wired, then you must also disconnect the wiring plugin from the smoke alarm.
3. Once you have the smoke detector down from the ceiling, remove the battery if still needed, and hold down the test button on the top of the smoke alarm for about 15 to 20 seconds. Any residual smoke detector beeping will drain from the electronic capacitors and circuitry within the smoke alarm.
4. Next, the smoke detector must be cleaned from dust that accumulates over time. There are several methods to do this. Vacuuming is the method recommended by many manufacturers, but some electronics experts recommend against vacuuming due to static electricity created, which can damage some electronic components. Another effective method, and the one we recommend, is to blow out the smoke detector with compressed air. If you do not have an air compressor, you can easily use a can of compressed air purchased from your local home goods or office supply store. Make sure you blow out the detection vent on the front surface of the smoke alarm, inside the battery compartment, and around the side openings around the smoke detector. Reinstall the smoke detector and insert a charged battery. In most cases, the smoke detector beeping will stop. If it does not, see the notes below.

Other Notes for Smoke Detector Beeping
In some smoke alarm brands, one weak battery in a wired system can cause smoke detector beeping in all smoke alarms.
Some smoke detectors expire after five to seven years, and none of these steps will stop smoke detector beeping. You will need to replace the affected smoke alarm. Some of the top-rated smoke detectors are found HERE.
