Power Fail Menu

Menus → System → Power Fail
In the event of AC power failure, an AC version instrument's power switches to DC if
properly wired. The switch from AC to DC power is automatic and does not require
5X00 configuration. Enable Power Fail AC Monitor to generate an event when AC
power fails and is restored. Because AC powered 5X00s may not reboot properly
after an AC power failure or AC power surge, it is highly recommended to use
a battery back system when 5X00 is powered primarily by AC power. See page
216 for DC battery maintenance information.
Disabling the Power Fail System will disable AC power events and disable the General
Alarm in the event of low battery for DC power. Disable Power Fail AC Monitor
when powering 5X00 by a DC power source.
Enable Low Battery Monitor to trigger General Alarm in the event DC voltage is ≤
to low battery trigger. The Low Battery Alarm Hold Off time is five (5) seconds and
cannot be user configured. Once the low battery general alarm has been acknowl-
edged by pressing one of the 4 softkeys, it is not reset. See General Alarm - page 131.

lowed by seven digits. 5500D-01, 5500D-02 and 5500D-04 instruments' serial
numbers begin with "55-" followed by seven digits. Serial numbers are generated
