Yeah. It is a 4 head minimum calc. Even if each room has only 1 sprinkler, you still must calc 4 heads. Travis Mack, SET MFP Design, LLC www.mfpdesign.com

See, I really should read the whole email prior to posting. If your full 13, you will still need to be at .10 gpm/sqft per spacing, and if your doing room design, you will still need to pick up 2 sprinklers in the communicating spaces... Not many residential occupancies have rated doors...
