Change the Batteries

When your Vivint smoke detector battery gets low, you will be alerted on your panel first. The smoke detector itself will chirp every 48 seconds when the battery level becomes critical. You can open up your smoke detector to see what type of batteries it needs, but please review the steps below thoroughly first to avoid triggering a false alarm in the process. If your sensor’s batteries are low, complete the following steps to replace them.

1To prevent false alarms and tamper alerts, put your panel into Test Mode. Select your panel below for steps on how to put your panel into Test Mode:
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. Steps 4 and 5 are important to ensure a full reset of the device. If skipped or done improperly, the detector may not recognize the new batteries and continue to chirp.
6Replace with 3 new AAA batteries or one CR123A battery depending on which smoke detector you have.
7To twist the cover back on, place the smoke detector against the mounting attached to the ceiling and slowly twist counter clockwise. The bottom will catch and once that happens, change direction and twist the detector clockwise, applying a light amount of force toward the ceiling. It will lock into place with the raised tabs on each piece lining up. For a visual demonstration, watch the video above.
8Safely dispose of the old batteries and be sure to exit Test Mode on your touchscreen panel when you’re finished.
