You're not allowed horizontal mullions or molding. The glazing can be separated by vertical mullions so long as each panel has its own sprinkler, but horizontal bumps are a deal-breaker.

Would 2½" mullions spaced at 4'-0" on center with the window height at 9'-0" (with no sills) be considered a similar feature? and require separate sprinklers? it seems like it is addressing horizontal projections only.
