What does the red and green light mean on a smoke detector?

Why is my smoke detector whistling?
When smoke detectors are activated by the by-products of combustion (smoke) they emit a loud screeching noise. If the detector is just emitting an intermittent “chirping” noise it means that the battery needs to be replaced.
Why does my smoke detector keep beeping after I changed the battery?
Newer smoke alarms keep some errors in the processor. The smoke alarm must clear errors after the battery is changed, but it might continue to chirp even after you change the batteries. When this happens, the way to stop the chirping noise is to reset the smoke alarm to manually clear the error from the processor.

What does a steady green light mean on a smoke detector?
The steady green light indicates that the detector is receiving line power. The short red flash every 30–60 seconds indicates that the internal self-test for proper functionality has passed. If you carefully remove the detector, the manufacturer and model number are on the back of it.
Why did my smoke alarm go off for no reason?
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.
