So I searched for one and did not find a AFDS CB and posted that I did not locate one, nor did I think I would.
Thanks to P3 Bellows for posting the CB Panel schematics and other info.
Furthermore I think the Floats Armed caption #2 explanation is to WARN you the floats are ARMED when you are on the ground, floats are armed and the Nr is below 80% leading to the gens going offline leading to some dark screens if the APU is not on.
Just for clarity I have no idea how the S92 float system is designed or wired. Never flown it (apart from the demonstrator), I was just following up on a couple of other people who seemed certain that the AFDS element of the system was not powered when there was no generated power on the aircraft.
