UPS that is for certain parts of the building tripped on overheat (probably fan/filter issue). Source from utility was never lost, but the output from the UPS was off due to this UPS trip.

I'm a little surprised that the UPS output went down this since I would have expected the UPS to fail to a pass-through state for the utility source if the UPS trips on overheat like that. Trying to find manual/documentation on UPS, but until I do, anybody agree or disagree that this behavior is expected?
