Pre-Alarms
A pre-alarm is annunciated when a condition programmed to trigger a pre-alarm is met. When a pre-alarm
condition exists, it is annunciated (flashed) on the LCD, the front panel Alarm indicator flashes on and off
and the Horn output (if programmed and enabled) alternates between an energized and de-energized
state. The audible alarm is reset by pressing the front panel Alarm Silence pushbutton. When a pre-alarm
condition ceases to exist for most pre-alarms, all displayed annunciations are reset automatically. Certain
pre-alarms do not clear automatically and must be cleared by either pressing the reset button on the front
panel or providing an input to the Reset logic element in BESTlogicPlus. The following pre-alarms do not
clear automatically:
•
Weak Battery Pre-Alarm
•
Breaker Close Fail Pre-Alarms
•
Breaker Open Fail Pre-Alarms
