If you are asking about what voltage the UPS was triggering an alarm, we didn't see any alarm on the input side, just an alarm when the output voltage dropped to 107.
I can check the model number of the recorder, if you would like.
The power company has never been known to be highly reliable. I keep batteries in the alarm clock so it doesn't reset itself to midnight a couple times a month. It used to be alot more often than that before I moved from an apartment into a house ...
