If the sprinklers are 18' apart or 9' off of walls, then 5 x 324 SF would be correct.

You need to calculate 5 ex COV sprinklers at a minimum. You don't have to do 5x324. If they only cover 1400 sq ft for whatever reason so be it. You still calc 5.

WHICH IS 1620 SQFT. WONDERING IF I AM READING THIS RIGHT? I DON'T SEE THE ADVANTAGE WHEN I CAN USE 7 STANDARD Q.R. SPRINKLERS TO COVER THE SAME ROOM. 11' CEILINGS MY DESIGN AREA WOULD ONLY BE 923 SQFT. AM I MISSING SOMETHING?
