When it does that, do you see the current status ("ups.status" line in upsc
output) go from "OL" (online) to "OB" (on battery) to "OB LB" (on battery/low
battery)?

You didn't mention the output of upsrw (which has a few settings for
controlling when "LB" is set), but you can also synthesize the low battery
event:

for "ignorelb"

For your particular situation of one UPS and one master system, this should
shut the system down without waiting for the "OB LB" status:

Any other details you can provide on the configuration will make it easier to
isolate the problem.
