Things changed a bit from the sysv implementation (see http://www.apcupsd.org/manual/manual.html#system-shutdown-test)
when systemd came into the picture as many naïve or hack approaches
were no longer necessary. It looks like the current packages drop the
needed scripts in /lib/systemd/system-shutdown (see https://www.freedesktop.org/software/systemd/man/systemd-halt.service.html)
So now with the state file and that script, your UPS (if setup and possible)
will be signaled to interrupt power at a safe point once the daemon
initiates shutdown.
Your next startup log will indicate if a dirty mount was discovered.
You should also check /etc/apcupsd/apcupsd.conf for the behavior
and time values, there aren't many options and the file is short.
