When the SENSORs only BEEP it usually means a low Battery etc. You can RESET the alarm and it quits.
A CONTINUOUS ALARM indicates an actual alarm has been activated.
This is how most SENSORs operate at any rate...
I like to have two working CO DETECTORS installed in the same location as a PLAN B for false or "TEST" alarms.
Read your literature on how your installed ALARMS are suppose to work...
