Change the Batteries
When your Vivint smoke detector battery gets low, you will be alerted on your panel first. The smoke detector itself will not chirp until it gets to critical battery level. If it gets to that point, you will hear a chirp from the smoke detector every 48 seconds until the battery is changed. Our smoke detectors take either three AAA batteries or one CR123A battery depending on which model you have. We recommend using Duracell or Energizer batteries for the best results. If your sensor’s batteries are low, complete the following steps to replace them. You can open up your smoke detector to see the type of batteries it takes.
2Go to your smoke detector
3Twist off the top cover
4Take out the old batteries and wait two minutes
5Press the test button on the smoke detector with the batteries still out to ensure a full reset
6 Replace with new AAA batteries or CR123A battery depending on which smoke detector you have
7Twist cover back on
8Safely dispose of the old batteries
9Be sure to exit Test Mode on your touchscreen panel when you’re finished
