As George was fond of saying (I believe the original quote was by Roland). "ESFR is not a sprinkler system it's a building system" that may not be the exact quote but it's close.

I thought moving the heater may be the only answer. Though how you can do that with a 10'x10' ESFR spacing beats me.

I'm not aware of any 286F ESFR's but I haven't really look for them either. AFSA has great sprinkler head chart on their web site. And George was right, usually the unit heaters have to be moved because of the spacing limitations of ESFR's. It takes a lot of coordination early on in the project to prevent obstructions. We have the best results when we're on board before the structural design is completed.

(assuming no heat sources) (2) If there is a heat source, such as a unit heater, are there ESFR heads rated for 286 deg.F? I see only 165 & 212.
