LK that is a fairly odd situation.

First a display case in front of a panel is IMO a far cry from a picture in front of a panel.

Second there is no requirement that a panel is visible, the panel could be on another floor in a locked closet so to say immediate access is required is IMO a stretch.

It sounds like the card sorting machines lack of disconnecting means was culprit IMO.
