Table 2: Audible Beeps
Number of Beeps
What It Means
1 every 10 seconds
Line Loss: The unit is on battery power. See Table 3 for more information.
2 every 10 seconds
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.
Continuous
UPS Fault: UPS internal failure
3 every 5 minutes
0.5 second beep,
re-occurring every 1
second
3 every 10 seconds
Battery Undercharged: While on line operation, low battery voltage indicates
that the battery will provide minimal backup time.
Output Overload: Too much load equipment.
Replace the Battery: The battery needs to be replaced. See “Replacing the
Batteries.”
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.
If your Patriot Pro II runs on batteries frequently because the input utility line varies often, you
may want to adjust your Patriot Pro II to accept wider voltage variations before switching to
batteries. Appendix A describes how to adjust the Patriot Pro II from the front panel in response
to specific utility power problems. You should have an electrician check your nominal line
voltage and determine 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.
