Why did my smoke alarm go off when there was no smoke?

The most likely reason smoke detectors go off unexpectedly is that people aren’t changing the batteries in them often enough. That’s because smoke in the air will reduce the current. If your battery is dying, the current that’s flowing through your sensor also goes down. And so you can get a false positive.
