how to turn off the carbon monoxide alarm
You would clear the alarm from the alarm panel by entering your panel’s disarm code or by the Alarm.com mobile app or website.
As a follow up. I am not showing a carbon monoxide detector in panel programming. If you have a detector that goes off that is not associated with the alarm panel, you would need to clear the alert from the unit itself. Typically there is a silence button on the detector for this.
