When your Vivint CO detector battery gets low, you will be alerted on your panel first. The CO 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 detector every 48 seconds until the battery is changed. CO detectors take one CR123A battery. If your sensor’s batteries are low, complete the following steps to replace them:
2Go to your CO detector
3Twist off the top cover of your sensor
4Take out the old battery and replace with one CR123A or DL123A battery
5Twist cover back on
6Safely dispose of the old battery
7Be sure to exit Test Mode on your touchscreen panel when you’re finished
