Thanks for the quick response!

I'm not convinced this is the problem; I think that pfSense has
an alternative way of running the NUT components:
# ps aux | grep ups
root    45456   0.0  0.1   6796   884  -  Is   02:22    0:00.01 /usr/local/sbin/upsmon
uucp    45751   0.0  0.1   6796   772  -  S    02:22    0:00.10 /usr/local/sbin/upsmon
uucp    46796   0.0  0.1   6888   888  -  Ss   02:22    0:00.45 /usr/local/libexec/nut/usbhid-ups -a AVR750U
root    56752   0.0  0.1   6788   832  -  Ss   02:22    0:00.13 /usr/local/sbin/upsd -u root
root    39437   0.0  0.2   6828  2464  0  S+   02:46    0:00.01 grep ups

Is there anything else that should be running?

Would you expect `upsmon -c fsd` to not work as I described above
(system halting but UPS not power cycling) if MODE was set to none
but upsmon, the driver, and upsd were running?

You are correct about my location and expected voltage. Is there
somewhere that I can change the scaling factor used by NUT?
