Sounds like someone is blowing smoke up your..... well lets not go
there. The point is that, you can't eliminate buoyant smoke. You
eliminate the buoyancy of the smoke so that it drops to the floor. I
haven't seen any hard data on what density is required but applying
logic (which can lead one astray), once you are away from the fire
plume and simply pulling the heat out of the smoke, a high density is
not required.
It may be that their intent to provide enough overkill so that they
believe the fire will be knocked out avoiding the production of smoke
but I'm just guessing. Equivalencies for performance based BUILDING
design should have a high level of clarity. Is there more
information that the AHJ/building official (ie stakeholders) have
seen in accepting this approach?

This is also not a FM project. Any thoughts of the OH1 balconies for
elimination of buoyant smoke?
