- Red: When the detected CO level exceeds 200 PPM (All Sentry LEDs turn red).
- Yellow: When the detected CO level is between 75 and 200 PPM.
- Green: When the detected CO level is less than 75 PPM.
Alarm
- An audible alarm is triggered when the detected CO level exceeds 200 PPM.
In-App Alerts
- An in-app alert is provided when the detected CO level exceeds 200 PPM.
- A second in-app alert will be displayed after five minutes if the detected CO level continues to be greater than 200 PPM.
