Thanks for the info, it is very helpful. The strobe settings look right, assuming the ACC magnets are down.
I don't see photos of the fiber optic cables, from the second video it doesn't look like they are genuine Nauticam cables. PN 26211 should be used here. Four different strobes were tested today in my office, and they are all firing.
If you can test the proper cables that would be a good next step.
