This value reports the overall alarm status of a specific CO2 sensor entry in the Kentix appliance's co2InfoTable, using the shared AlarmStatusEnumeration scale (ok, notApplicable, other, nonCritical, critical). A monitoring system polls it to know at a glance whether a particular CO2 probe, identified by its co2InfoIndex, is reporting normally or has crossed into a warning or critical condition, without having to interpret the raw co2InfoValue reading itself. For example, a value of critical(5) on the entry for an external probe would indicate that sensor has reached its most severe alarm threshold and warrants immediate attention.
