2.2.2 General Power Supply Notes:
Supply power is measured on a 10-minute interval (battery / external supply voltages)
An Item is not used to choose between externally supply and battery powered
For Alarm triggering – three (3) consecutively low readings are required to the trip the associate
Alarm. This is done to help guard against falsely setting alarm due to a supply glitch
The Low Battery Voltage Alarm (Item 99) will not set if there is an External Supply voltage at
TB1 greater than the Battery voltage by over 1.0 volt
