This is F-2 <12% alcohol. So no separation issue. But still a vertical opening issue.

So it sounds like there are several issues. First the architect needs to revisit and verify the separation requirements between an F-1 and an A occupancy. If the findings indicate that a 1-hour separation is required, don't forget that is not just walls but floor/ceiling as well. Is there the possibility of providing glazing around the perimeter of the opening floor to roof deck above and then providing the type WS sprinklers by Tyco which are listed as providing the equivalence of a two-hour separation?

Is there seating on the first level and the opening is so you can see the equipment on the second floor? Per the IBC, for a fully sprinklered building there is a 1-hour fire separation requirement between F-1 and A. (Table 508.4) If that is the case, someone has a problem that sprinklers cannot fix.
