Huh? 8.2.1 very clearly states that maximum floor area ON ANY ONE FLOOR is to be 52,000 or 40,000 sq. ft. based on occupancy/hazard classification.

From: Sprinklerforum [mailto:[email protected]] On Behalf Of Jeff Bridges Sent: Thursday, September 01, 2016 10:46 AM To: [email protected] Subject: RE: 5 year fire sprinkler Obstruction Assessment - What items in a system define it as a separate wet pipe system? I would respectfully disagree with the below analogy. Example: (4) Story building consisting of 30K SF per floor Single lead-in supply- combo standpipe with floor controls. How can it be considered a single system when it exceeds the allowable floor space per riser? Just sayin’ Jeff Bridges JBFP Inc I have to disagree with this analysis that a floor control valve defines a system. A floor control valve is not even defined individually in 2013 whereas a sprinkler system is (no mention of floor control valves) as are control valves. As always, I would consider a system to be what it has always been and the addition of the required floor control valve and associated requirements on systems in multi-story buildings just nationally codifies a common practice hereabouts of building a system that has isolatable floors. This way an entire large building does not need to be drained to make a repair or for a T.I., leaves fore protection in service on floors not effected and also conserves water. I'm open to an argument that changes my mind but this one doesn't.
