To silence an alarm, press the
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 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
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.
