Your Nest Protect does some work behind the scenes, such as automatically running a Self Test to check its batteries and sensors or running a Sound Check (2nd gen) to check its speakers, buzzer and light ring.

You should also run a Safety Check-Up at least once a month to check that your Nest Protects are working properly.
