Advanced Analog Alarm Settings

The advanced Analog Alarm Settings window expands the basic alarm settings options to up to five severity levels.

Configure the following parameters:

Trigger Type	If the Trigger Type is Low, an alarm is triggered when the input drops below
	the specified Trigger value; other severity level trigger values must decrease in
	value with each subsequent level. If the Trigger Type is High, an alarm is
	triggered when the input is higher than the specified Trigger value; other
	severity level trigger values must increase in value with each subsequent level.
Clear Mode	To clear an alarm, the input must drop below the specified value when Trigger
	Type is High or go above the specified value when Trigger Type is Low.
Level 1-5	Defines the Level severity settings for up to five levels. If the Trigger Type is
	Low, an alarm is triggered when the input drops below the specified Trigger
	value; other severity level trigger values must decrease in value with each
	subsequent level. If the Trigger Type is High, an alarm is triggered when the
	input is higher than the specified Trigger value; other severity level trigger
	values must increase in value with each subsequent level.
