My understanding is that a beam or baffle does not work with ESFR sprinklers. This because the minimum square footage maintained by spacing requirements are figured into the 12 sprinkler heads used in the testing.

Spacing ESFR 25.2K PNTs on 10 x 10 spacing in 30' bays @ 16" below ceiling. Line are equally spaced 5' from center of 36" deep beams. I have an area where a full height wall is 11'-6" from a beam requiring an additional row of ESFR. When spacing the additional sprinklers at 8' between branch lines it places the additional sprinklers less than 8' from the adjacent line along the other side of the solid steel beam. Is the beam sufficient (only 20" below the sprinkler) to prevent skipping? Can I be less than minimum spacing (64sq.ft.) with the beam separating sprinklers? Scratching my head here.....
