Why is my fire alarm going off intermittently?
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.

Why did my smoke alarm go off in the middle of the night for no reason?

Most homes are the coolest between 2 a.m. and 6 a.m. That’s why the alarm may sound a low-battery chirp in the middle of the night, and then stop when the home warms up a few degrees.
