Smoke detector is chirping?

Try changing the 9V battery and dusting off the smoke detector

Tip: You should test your smoke detectors once a month.

To test the batteries, press and hold the test button for at least five seconds until you hear the beeps.

Replace the alkaline batteries every year.

 

Note: You should remove dust from your smoke detectors every six months.

Using a vacuum hose extension is an easy way to do this.

If your smoke alarm starts to chirp, you'll want to check the batteries and clean/dust the smoke detector to ensure there is not anything disrupting the sensors.
