"upsmon -c fsd" sets the FSD flag on all of the UPSes attached to upsd.

In the per-UPS context, FSD means that the UPS was commanded to shut down from an external source (a control panel, for instance).

If you want to experiment with various combinations of OB+LB on multiple UPSes, I would recommend swapping out one or more drivers with dummy-ups.
