Does a smoke detector make noise?
When your smoke detector makes a repeated beeping noise, it is usually trying to signal that the batteries within the unit need replacement. Once you have placed new batteries in the unit and reconnected it to the base, the beeping should stop. However, the noise can also signal you that something else is going on.

This battery characteristic can cause a smoke alarm to enter the low battery chirp mode when air temperatures drop. 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.
Why do smoke alarms go off at 3am?
