R2AlarmDeviceExt (Alarms) is a special variant of the ObixAlarmDeviceExt component, as a frozen device extension under an R2ObixClient. It allows integration of “native Niagara R2 alarms” from the client into the NiagaraAX alarming subsystem. Its default view is the ObixAlarmManager.

See “About the Alarms extension” in the Drivers Guide for general information. For more specific details, see the “R2ObixClient Alarms” section in the engineering notes document Niagara R2 to NiagaraAX via oBIX.
