Facility Alarm Tool
The Facility Alarm Tool is basically a conditional Image Tool. The image is displayed only when the object’s alarm criteria is met. The alarm criteria is based on four properties: [Facilities], [AlarmAckFilter], [AlarmStatusFilter], and [MinPriorityCategory].
Note: This tool is for alarms that are reported to the Common Alarm Service (CAS), not just an alarm bit that is enabled.

The [Facilities] property defines one or more meters for which to monitor alarms. The [AlarmAckFilter] property filters display of the image based on the acknowledgment state of the alarms. Options are 0 - All, 1 - Unacknowledged; and 2 - Acknowledged. If set to 1 - Unacknowledged and any of the facilities have an unacknowledged alarm, the image will be displayed. The [AlarmStatusFilter] property filters the display of the image based on the status of the alarm. If set to 1 - Set Only, the image will be displayed only when one or more alarms are in the "set" state. In other words, it excludes alarms that have been "reset" but still reside in the CAS. The [MinPriorityCategory] property filters display of the image based on the priority category of the alarms. Alarm priority is a property of the alarm specified in the point’s configuration record.
The [Image] property defines the image displayed by the object.
The Layout property specifies the image’s relationship to its boundary. If set to Left, Right, or Center, the image is set to its original size and proportions and is aligned within the boundary in the top left corner (Left), the center (Center), or the bottom right corner (Right). If set to Size to Fit, the boundary is resized to fit the image’s original size and proportions. If set to Stretch, the image is sized to fit within the object’s boundary (proportions are not maintained) and can be resized by dragging the object’s boundary. To maintain the current proportions while resizing, hold down the Shift key. To resize the image one pixel at a time regardless of TheView’s grid settings, hold down the Shift key and use the cursor keys.
If you want the image to be resized when the screen is resized in Run mode, its Layout property must be set to Size to Fit and FlexHorizontal and FlexVertical must be set to Expand or Proportional.
