Alarm Summary display should have a safer mechanism to acknowledge alarms to assure the correct alarm is being acknowledged

The expectation is that the chance of acknowledging the wrong alarm should be minimalized.

One solution to this would be a two-step process. The first step would be to request acknowledgment by clicking on the alarm. In the second step, a confirmation window would appear. This window would identify the alarm and allow the controller to confirm alarm acknowledgment or cancel the request. The window would have to operate for both point and system alarms.

We might even need to consider that this is needed for certain classes of points (e.g. 'safety-related', a term that is being used specifically in the midstream control rooms of our customer base, as well as the regulator), and/or certain severities, and/or certain alarm types (i.e. HIHI, but not RTN).

It would be expected that many customers would not like a 2-step process particularly since their controllers are already used to current behavior. We'd therefore have to make the two-step process user-selectable.

Minimising accidental alarm acknowledgements is important as these ack's are auditable activities that reflect on the capability of the operator to properly respond to the alarm.
