Moving clouds
Moving clouds
(OP)
So this question, and wonder if there is an answer.
have an auditorium ceiling cloud that moves 39 feet up and down and requires fire protection.
The auditorium is approximately 6400 square feet total. There are 9 clouds over the seating area ranging in size from approximately 9' x 9' to one that is approximately 35' x 18'. These are not square but unique shapes. The panels move up and down for acoustical purposes from 43' down to 29'-6" and then can be lowered down to 4' for maintenance purposes. The panels are also wood finish combustible material.
The clouds can be raised to within 2' of the ceiling

I am interested as well. For the interim, I feel this may be "Outside the scope" and will require ,Performance Engineering.

Not my problem, just saw the question and was wondering if anyone had a solution.
These I take are horizontal obstruction with measurements between

I am sticking with performance based, however that section could be used as a basis. We all know the fire is contained, not out, and we don't have to get water ON the burning item, just rob it's ability to produce.

RE: Moving clouds
Maybe a deluge to make sure everything gets wet and limit the spread of fire and smoke? I could see using braided separations to handle small movements but 39' is too great a vertical distance to maintain fire sprinklers as we currently practice it. Also there would be no way to fasten it to building structure per chapter 9 of NFPA 13.
These goofy ceilings usually take precedence over fire protection practices; good or bad.

that are not fixed in place, such as conference tables." could apply to this situation, but a giant leap away from the (probable) intent. This is an interesting exercise at least, you could end up asking for a Formal and/or informal Interpretation through NFPA/AFSA.
RE: Moving clouds
I moved / added sprinklers a few weeks ago because the acoustic calculations would not support them being lower than a few inches from the deck to route my measly 1¼" pipe. So acoustical dynamics is added to the list of priority items over life safety.
Having said that, this example I believe cannot be protected per 13. I know it cannot. It will need an "equivalent" level of protection, with lots of signature from folks more important then me. Interestingly, reflecting on deluge seems plausible.
Or to go even further outside the box, I liked the "Grate" sprinklers when they came out for hangers. If we cannot fight them from above, we go under.
Just some mental exercise with coffee this am...
