This issue came up years ago while working with Jim Bell of Marriott Corp on one of their assisted living facilities a 13R that I have always used the same logic since then, and applied it to 13D as well. (1992) At that time Marriott had about 2 fires per year in sauna's, typically caused by bottles of body oil or towels placed over the heater. Jim's requirement was to sprinkler all sauna's using 300+ degree heads as the emergency cut out for sauna controls is typically set in the high 200'F range. We currently install 360'F TYCO TY-B either 2.8K or 5.6K depending upon room size. (Yes I know they are STD response, but as we discussed at the time, in a 8x10 room, any protection is better than none, and Std response Vs. QR will be a matter of only a second or two, with the ambient already over 100'F.) 286'F heads are ok if your emergency cut off is set lower than 236'F, which I've never found one that low. That's what we do and AHJ's only need to hear this logic once to accept it.
Steam rooms, same source at Marriott, "What can burn? Tile walls, floors and ceiling, in a basic "Mist" system." Now Marriott used steel studs everywhere, so if your steam room is framed with wood and you have the steam generator in the typical under bench location, what we've done is put a head in that space, again high temp. If the people or wet towels "spontaneously combust" in a steam room not much a sprinkler can do to save them. I'd like to hear what others are thinking. 200'F heads will go off way too often, 286'F may never go off if the emergency cut out is never needed, but I know that if a 360'F head goes off, it's either a fire or mechanical damage.

What temp sprinklers should I use, and is it permissible to use QR instead of Residential? I'm thinking that I will need high temp heads and residentials only go up to 175F, at least the ones that I'm familiar with.
