An alarm trigger is the condition for which an alarm reaction should be executed. For example, quality managers might want to know when yield drops below a certain level in production to prevent it from dropping further. In this example, you would configure two levels of triggers for yield alarms for which users might configure different Alarm Reaction templates:

Set a warning threshold to send an email warning the appropriate personnel that a condition on the factory floor is starting to go out of its boundaries.
Set a threshold to not only send an email, but also send a line stop to an inForce unit to prevent more assemblies from being built incorrectly.

Alarm triggers

Available alarm triggers are shown in the following table.

Alarm trigger type	Description

Alarm trigger type	Description
Materials (Materials Related)	Inter-Service Usage Total Life Usage Tooling Inter-Service Usage Tooling Total Life Usage
Materials (Setup Related)	Time to Empty Time to Empty Part Detail Units to Empty Units to Empty Part Detail
Quality (Defects Per Million Opportunities) (DPMO)	Batch DPMO Operation DPMO
Quality (Misc.)	Batch Total Units Failed Operation Total Units Failed SPC Cpk Batch AQL Rejected New Operator Feedback
Quality (Yield)	Batch First Pass Yield Batch Second Pass Yield Operation First Pass Yield Operation Second Pass Yield Workstation First Pass Yield Workstation Second Pass Yield
Logistics	Expired Materials Batch Schedule Overage

Note

The following example assumes that you already created two Alarm Reaction templates: A Warning Email template and a Line Stop template.

Alarm trigger example

Log into the Analytics client application, then select Alarms.
Select the Alarm Triggers tab.
Select the Quality (Yield) category on the left side of the window, then select the Operation First Pass Yield trigger under Trigger Types.
Select the Add New button, then enter a Name and optional Description. (For this example, we named the trigger First Pass Yield Trigger.)

You can set the warning and error thresholds along with the desired alarm reaction template to "fire" once each threshold is reached.
Specify a Trigger Start Point of 15% to prevent excessive alarms resulting in the first or second assembly failing which would result in a First Pass Yield of 0% or 50% respectively.
Under Warning Threshold, enter 98% next to When operation yield rises to or above.
Next to When operation yield drops below 98%, select Warning Email Template from the fire reaction template drop-down.
Under Error Threshold, enter 95% next to When operation yield rises to or above.
Next to When operation yield drops below 95%, select Line Stop Template from the fire reaction template drop-down.
Select the Active check box at the bottom of the window to make the new alarm trigger available/functional, then select Save.
