You can also use Table 6.2.5.1 which indicates max. ceiling temps. It seems one should be able to justify the potential of greater than 100°F temperatures in a laundry room thus indicating an intermediate sprinkler should be installed as a safeguard...and still meet the standard.

I just wanted to make sure I wasn't way off base on this. I am submitting an AFSA informal interpretation, as well as a technical question to NFPA to get the answer to provide to this plan reviewer as well.
