Just as Gregg describes (full coverage above with pendants below) that is the requirements we use here. I however, do believe this is addressed in NFPA13. Simple as providing coverage at the roof like always and providing heads under obstructions, similar to sprinklers under ducts. The only point of discussion on the subject in my opinion, is exactly how many and how large can openings be in a concealed space before it is no longer considered a concealed space.

Since no specific code addressed this, the AHJ made the final decision. For what it is worth, Gregg Fontes Cen-Cal Fire Systems, Inc.

Structure above is steel joist - approximately 3'-0" clearance from top of panel to bottom of decking. I do not believe these panels fall under the "Drop-out Ceiling" section... therefore, I'm wondering if my spacing would be to place deflector within 6" of the deck and place around / near the openings created between the panels. Any thoughts, previous experiences? Knowledge from the forum is always appreciated!!
