Configure the following parameters for the source(s) for each Smart Alarm.
Every Smart Alarm must have at least one Source assigned to it.
Alarm Sources
Parameter Setting
SA Num Type the number (from the Smart Alarm States table) of the Smart Alarm for
which this source is an input.
Status Set to Enabled.
Trigger When
Source Is
Set to either:
Triggered - the Alarm Source will become active immediately when the
conditions for this alarm become true (or false when Logic is set to NOT). The
alarm needs to be enabled and set with any severity, including Control.
Do not use Triggered when Type is set to Smart Alarm.
Active - the Alarm Source will become active when the alarm becomes active
(or inactive when Logic is set to NOT), after the alarm recognition time, and
only if the alarm is Enabled.
Type Set to the appropriate source type: System Alarm, Analog Input High, Analog
Input Low, DI, Smart Alarm.
Index Identify the alarm:
Source Type = System Alarm:
Web - select the name of the system alarm from the list.
Source Type = AI High/AI Low - type the alarm number from the Analog Input
High Alarms or the Analog Input Low Alarms table.
Source Type = DI - type the alarm number from the Digital Input Alarms table.
Source Type = Smart Alarm - type the alarm number from the Smart Alarm States
table.
Invert The source is inverted before it is used to trigger the Smart Alarm. The Smart
Alarm will be triggered when the source becomes inactive.
Active Count Sets the number of transitions before the Smart Alarm becomes active. E.g. If
this is set to 2, then two inactive to active transitions are required before the
Smart Alarm becomes active.
Inactive Count Sets the number of transitions before the Smart Alarm becomes inactive. E.g. If
this is set to 2, then two active to inactive transitions are required before the
Smart Alarm becomes inactive.
Trigger Specify how the source is used to trigger the Smart Alarm.
Level – triggered as long as the source is active.
Edge Set – triggered when the source becomes active.
Edge Reset – triggered when the source becomes inactive
Edge Latch – triggered when the source becomes active. The Smart Alarm
