If your Fortress runs on batteries frequently because the input utility line varies often, you may
want to adjust your Fortress to accept wider voltage variations before switching to batteries.
Appendix A describes how to adjust the Fortress from the front panel in response to specific util-
ity power problems. You should have an electrician check your nominal line voltage and deter-
mine if the problem is due to a “Surge” (high) voltage or “Brownout” (low) voltage. Changing
the setting without this knowledge could make the problem worse.
To silence an alarm, press the alarm silence button on the front panel. The beep will stop, but the
alarm light will stay on. Note: Silencing the alarm does not solve the problem that caused it. See
Tables 2 and 3.
Symbols and LEDs What It Means
Steady: Acceptable input power is present. The unit is
running on line power.
Off: No input power is present or the unit is switched off.
The unit is running on battery power.
Output Overload: Refer to Tables 2 and 3.
Replace the Battery or UPS Fault. Refer to Tables 2 and 3.
Blinking: The unit is boosting or bucking utility power.
Boost = Automatically increases low input power to prevent
the unit from switching to battery.
Buck = Automatically decreases high input power to prevent
the unit from switching to battery.

Low Battery Alarm: The unit was running on battery power and shut down due
to very low battery voltage. The unit will restart automatically when acceptable
power returns.

1) Output Short Circuit
2) Starting Fault: Input voltage out of range when unit is turned on.
3) UPS Fault: UPS internal failure.
