Smoke Detector Keeps Beeping

My hardwired smoke detector keeps beeping. I tried turning off all breakers, but it still beeps. I tried vacuuming the unit and wiping, that didn't help. It beeps about every 60 seconds. I disconnected the detector from the wiring, but it still beeps from the hardwired sensor. How can I get it to stop?

Some hard wired smoke detectors have a battery in them for back up if there is a power failure. If the battery is running low the smoke detector will start making a chirping sound just as you described.

How old is it? It may need to be replaced. I think they're worn out at about 5 years.

Yup, clean the sensor and change the battery. If that doesn't work it may be too old and you need to replace it.

I had the same problem this morning with mine. I did the same as you. I disconnected the entire unit and battery, took a while, but it finally stopped. My guess is it needs replacing.
