M1 Mac Mini Fails to Shutdown with APC UPS Options (Monterey 12.2.1)

I have an M1 Mac Mini that needs to auto-shutdown after 60 seconds on the UPS. We are using an APC Back-Ups 850VA model connected via USB. Also, this M1 mac mini has had its data migrated from a Time Machine backup of an Intel Mac Mini running OS X El Capitan 10.11.6. The mac properly recognizes the UPS and lists the UPS options in the Energy Saver preferences, however no matter what I set within the UPS settings, the UPS does not shutdown the machine. The only thing that does work is a warning when the Mac Mini is drawing from the UPS. **Does anyone have any suggestions? Nothing in the previous threads have worked.** Here are the relevant settings: **pmset -g** System-wide power settings: Currently in use: disksleep 10 powernap 1 womp 1 networkoversleep 0 sleep 0 (sleep prevented by coreaudiod, bluetoothd, powerd) Sleep On Power Button 1 ttyskeepawake 1 tcpkeepalive 1 autorestart 1 standby 0 **pmset -g ups** UPS settings: haltlevel on 100 haltafter on 1 haltremain on 15 **When UPS plugged in:** Now drawing from 'AC Power' -Back-UPS ES 850G2 FW:931.a10.D USB FW:a10 (id=25296896) 74%; charging present: true **When ups unplugged:** Now drawing from 'UPS Power' -Back-UPS ES 850G2 FW:931.a10.D USB FW:a10 (id=25296896) 74%; discharging; 4:14 remaining present: true
