Are sprinkler heads required under fabric art – art hung 3’-0” from ceiling circles approximately 5’-0” wide.
Technically almost any obstruction over four feet is required to have sprinkler protection under it.
So are they around five in diameter or radius??
And are they in like a circle frame, or loose in some manner.
How are you connected with this? Is it planned to be installed or already there?
OHHH I am not an engineer, so you can discount my reply if you want, and I cannot do math.

The hanging artwork appear to be similar to hanging privacy curtains. I am going to say no when installed in accordance with Section 18.104.22.168.2 of the 2016 NFPA 13. Unless there is more to add from the discovery of facts that change the parameters.
Where the tops of the hanging art work exceed the minimum vertical distance below the ceiling mounted shown in Table 22.214.171.124.2 the horizontal distances from the artwork is not applicable. Therefore, the artwork will not limit the existing sprinklers' distribution from reaching the protected hazard.
Excerpts from 2016 NFPA 13:
I can not speculate what the local building codes and regulations are for the location of sprinkler with the hanging artwork.
Let us know if this makes sense to you and was helpful.
Jeanette, I had a similar situation a few years ago in a recreational facility with a kids zone for babysitting. The kids zone had fabric leafs (approx. 2'x3') installed 4'-5' below the ceiling at multiple elevations. We tried to explain to the AHJ that the fabric obstructions would most likely not trap enough heat to be of any real value to any sprinklers under them and that they would be moving around with the air flow under normal climate control circumstances as they were to be suspended with wire and not fixed in place. The AHJ wanted us to put sprinklers under the fabric leafs still even though the sprinklers could be subject to mechanical injury from the metal leaf frame. We finally convinced to AHJ to allow sidewalls to be placed below the elevation of the fabric obstructions in the wall as the AHJ was adamant that they needed to be protected and dropping heads below from above was not practical, but neither are the sidewalls but the installation makes more sense and is less invasive and the entire floor area remains protected.
There is always more to add from the discovery of facts that change the parameters.
NFPA 13 standard does not have enough prescribed standards to deal with fabric obstructions under sprinklers. If I were the AHJ, I would require a fire protection Engineer evaluation.
Ultimately, it is up to the Engineer to recognize these dangers. No standard can instruct on the knowledge of the equipment design, its operating materials, or which standard apply.
