Hello all, In our control room, we have four I/A 8.4.3 XP operator workstations. Operators wanted the workstations grouped in pairs for alarm management. So I configured two alarm groups, with 2 WS each (say WS1/2 and WS3/4), and set the clear alarm option to "Delete alarm throughout the CAG". Everything worked as expected. But there is a problem: operators want the "Silence Horns" function to work on both groups at the same time (i.e., pressing the "Silence Horns" button in any workstation silences horns in all workstations). For what I know, it can't be done... As an alternative, I could put all the workstations back in the same CAG to solve the "Silence Horns" problem, but I would need some trick to make the clear and ack alarm function work in pairs (i.e., clearing alarms in WS 1 also clears alarms in WS 2 and vice-versa, but doesn't affect WS 3 and 4; clearing alarms in WS 3 also clears alarms in WS 4 and vice-versa, but doesn't affect WS 1 and 2) As for why would anybody want to group 4 WS that are a few feet apart from each other in two groups... well, it's one of those Operations things.
