Common questions about “Google Nest Protect alarm showing a yellow ring and two chirps every 60 seconds”
What does a yellow ring and two chirps every 60 seconds mean on a Google Nest Protect alarm?+
Protect has expired under safety regulations. Google says Protect sounds a double chirp once a minute, and that you will not be protected from smoke or carbon monoxide if you do not replace it.
How long does a Nest Protect last?+
It expires on a fixed date set by safety regulations, after which it signals with two chirps every 60 seconds, and the alarm must be replaced.
Where do I find the expiry date on a Nest Protect?+
It is printed on the back of the alarm, and the Google Home app also shows when the unit expires.
Can I silence an expired Nest Protect?+
Only for a short time. It keeps chirping until it is replaced, and because it no longer meets safety regulations it should not be left on the ceiling.
Will a new battery stop a Nest Protect's two-chirp expiry warning?+
No. The alarm has reached the end of its life by date, and only replacing the Nest Protect clears the signal.
Can I silence the two chirps every minute?+
Pressing the Nest button hushes the chirp for a time, but an expired alarm will keep chirping until it is replaced, so treat the silence as a short reprieve.
Why does an expired Nest Protect keep chirping after new batteries?+
The expiry is set by the alarm's own sensors and manufacture date, not by the batteries, so new batteries will not stop it. Replace the alarm.
