Do a google search for the ceiling and flex. There was a test done specifically for this.

He needs to prove that they can’t be used. Call Victaulic. I would imagine they can get you something.

He says that they are so flexible that when a sprinkler goes off the jet effect is going to lift the sprinkler up through the ceiling. I told him that the drops are mechanically attached to the ceiling grid and in order to lift up they would have to lift the entire weight of the ceiling grid, ceiling tiles, the lights and HVAC diffusers. His answer prove, it either by letter from the manufacturer or from someone a lot higher up the food chain than either he or I am. Or something specific in NFPA 13 that says he is wrong.
