Todd, I don't believe Open Grid Ceiling rules will apply. The material can't be any thicker than the least dimension of the opening. If it is a wood frame material like 2x solid wood then you will have an obstruction to spray pattern to worry about. Once you get all the information on the slatted ceiling solutions will be easier.

The ceiling construction is a fire rated wood and is considered non conbustible. There is a 2' wide sheetrock soffit around the perimeter and the slatted area is approximately 6 ft wide down the middle. The space above the ceiling is non combustible and would not normally require sprinklers. The FM has raised a question if sprinklers below would operate given the openings (I am trying to get the dimensions of the openings and the slats). I did not see anything in 13 addresses this. Am I missing something? Thoughts?
