NFPA 13 (10) section 11.3.1.1 also includes “adjacent”. What does this mean actually? 4 heads on the same line regardless of the walls or 4 heads in the same area but may be supplied from different lines? The pictures in the appendix are not very clear.

NFPA 13 says that when using residential heads, you calculate the 4 heads that produce the greatest hydraulic demand. No mention of units, rated walls, corridors, type of construction, etc. I didn't know George Church, but I would have liked him. ------------------------------ *From: *"Travis Mack" <[email protected]> *To: *[email protected], "sprinklerforum" < [email protected]> *Sent: *Tuesday, July 5, 2016 3:44:35 PM *Subject: *Re: Dwelling Unit Sprinkler Calc I'd probably grab the adjacent sprinkler in the adjacent room.

They each have three Residential Sprinklers. 13 requires a four head calc. Can I calc the 3 residential sprinklers and pick up one QR sprinkler in the corridor and still satisfy the 4 head requirement? Or, should I pick up one residential sprinkler from an adjacent dwelling room?
