Alarm Bell
The annunciator. It sits in a corner of every operator screen and answers one question continuously: is there anything outstanding? Clicking it opens a summary popover where an operator can acknowledge without leaving the screen they are on.
Alarm Event
The live active-alarm list, with state, a severity accent, filtering and acknowledgement. Place it on the alarm screen as the main list, or scoped to one area beside the equipment it belongs to.
Alarm Journal
The append-only history of every alarm lifecycle event — raised, acknowledged, returned to normal, shelved, suppressed, restored — searchable and filterable, and fast over months of data.
Alarm Performance
The ISA-18.2 performance view: alarm rate over time, the top bad actors, the split by priority, and the standing-alarm count. This is the screen you use to improve the alarm system rather than to operate it.
