We have (2) MGE UPS units in our facility and it is connected to the (BAS) via an open J-Bus xDriver. When the (2) UPS Units are online, we are recieving ramdom alarm notifications along with the power monitoring data.

When (1) UPS Unit is "off-line", the random alarms stop. When both UPS units go back on-line, the random alarms start again.

What could be the problem? Is this a polling issue?
