Summary of the Article: Smoke Detector Blinking Red or Green
A smoke detector blinking red could mean that it is working properly or that you need to run a test to ensure it is functioning correctly. Regularly testing your smoke alarms helps identify any issues before a fire occurs.
If your smoke detector is blinking red but there is no sound, it typically indicates that the unit is receiving power.
When a smoke alarm blinks red every 10 seconds, it is temporarily desensitized. This can happen when the alarm is silenced by pushing the Test/Hush button on the smoke alarm cover and the smoke is not too dense.
If the smoke detector continues to detect smoke, it will automatically reset itself after 10 minutes and sound an alarm again. To manually reset the smoke detector and stop the red blinking light, press the test/silence button for a few seconds.
Almost every residential smoke alarm blinks to indicate that the battery or power supply is functioning properly. A correctly operating smoke alarm will flash a red light once or twice every minute.
If there is no green light on your smoke detector, it means that the AC power has been interrupted. Check the circuit breaker and AC wiring to correct the issue.
In the case of a First Alert carbon monoxide alarm, the red light flashes to indicate that the alarm is receiving battery power. If the red light is not flashing, change the batteries immediately.
To check if your smoke detector is working, press and hold the test button on the detector. It may take a few seconds, but you should hear a loud, ear-piercing siren.

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.
How often do you need to change the battery in a smoke detector
once a year
Test smoke alarms every month by pressing their test buttons. If your alarms use regular batteries, swap in fresh batteries at least once a year. A “chirping” sound means that it's time to change batteries. Because alarm sensors wear out, replace each alarm at least every 10 years.
