Asked: Some sort of alarm went off in my house? What could it be?

Some sort of alarm went off in my house.I'm not too familiar with what happened as this is a new house and I've only been living here for 3 months.
2 days ago our A/C shut down for some reason.

It is the middle of the night and some sort of the alarm went off.It came from the thermostat.
Could this indicate high carbon monoxide levels?
What could it be?
