Since NFPA 13 specifically addresses them, as long as the i's are dotted and t's crossed, why not?
I see a dilemma if the hazard below the ceiling happens to be 'light'. Section 8.15.15.2 (2013) doesn't allow QR sprinklers to be used above drop-out ceilings. So if the hazard happens to be 'light', you could argue that NFPA 13 provides no acceptable way to protect it.

How are you handling them? I have never really been a fan of these things. A customer has a job where the builder is wanting to use these tiles to eliminate the need for sprinklers at the ceiling. We did the shell space and there are 155 degree uprights at the deck. This is 1st floor of a 4 story building. The tiles are rated at 165f. The sprinklers will have to be changed to 200F so the sprinklers will activate after the tiles fall. What is your thoughts on these things?
