Have you looked into the event logs?
You can find it under 'Aquaero/System/Event log'...you must download the log data from the device first to see the messages.
Didn't even know that was there, thanks for that.
I found the issue. The first alarm was most definite the Aquaero, but it seems that the rest were my UPS trying to get my attention. It sits right next to the computer, so the sound was coming from the same general area. Apparently the UPS wants a new battery.
