CO2 detectors (sold as indoor air quality meters) are becoming more of a thing as companies have figured out that baselessly scaring informing people about their indoor air "quality" is profitable.
CO2 Alarms are definitely not a common thing in residential buildings. I agree with you that OP almost certainly has a Carbon Monoxide alarm going off.
