The banner receives the list of active alarms and selects the alarms to show. Unacknowledged alarms come first, then higher priorities, and among equal alarms the oldest one, which has been waiting the longest. Priorities follow ISA-18.2, and an unacknowledged priority 1 alarm blinks until it is acknowledged.
Events raised by the banner are listed here.
The maxVisible property shows a stack of alarms instead of a single row, for example on a wall display that covers several areas.
Turn off the acknowledge button and the timestamps for an informational strip. Both are on by default. Boolean attributes work by presence, so show-acknowledge="false" would turn the button on; set the properties from JavaScript instead.
