If they cover less, then you still have to do the minimum area.
Keep this simple. 5 sprinklers minimum. If the 5 sprinklers doesn't
get your total area using the density/area curve, then add sprinklers
until you get there.

its say on page 598n 2013 handbook. ``if the reduction of area is
applicable such as that the minimum area density area was 900 sqft,
then the 1280 sqft area would be required.`` according to 11.2.3.2.2.3

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

You are reading wrong. 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.

I HAVE A 750 SQFT CLASS ROOM. DUE TO THE CONFIGUARTION OF THE
LIGHTS AND A FEW BUMP OUTS IN THE WALLS. I NEED TO USE FIVE
18x18 EC SPRINKLERS.
IF I READ THE CODE CORRECTLY. I NEED TO CALCULATE 5 TIMES 324
SQFT. 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?
THANKS
