Why is My Smoke Alarm Chirping?
If you’ve only just installed it, make sure you’ve removed the yellow battery installation tag. If your smoke alarm is not new, and runs on 9V batteries, it will chirp at regular intervals when the battery needs to be replaced. Get a new battery as soon as possible and follow the manufacturer’s instructions in your User Manual to correctly change it.
I’ve Changed the Battery – But It’s Still Chirping?
First, check the battery terminals are in contact with the battery and give the smoke alarm a clean with a vacuum to suck out any dust particles. If your alarm has a Hush mode, it’s possible the button may have been accidentally pushed when the battery was changed. If it’s still chirping when attached to the ceiling, it could be in Hush mode – leave it for 5-10 minutes without pressing any buttons, to allow it to complete the Hush cycle.
