this problem comes from the fact that your unit isn't
well supported.

To launch a shutdown, upsmon need to be instructed
first with an "OB" flag, and then an "OB LB".
Otherwise, if you have "OL LB", you might have rebooted,
and the system don't need to be shutdown as the power
is present... So we clearly can't shutdown upon "OL LB"...

So the only solution for you is to look at the driver you've used
(BTW, which one did you use?), and to adapt it to better handle
your UPS... As a temporary solution, you might have a look at
upssched to handle your situation, and shutdown upon "OL LB",
calling "upsmon -c fsd"
