Apology accepted ;) a real head-scratcher--- i thought of a few things, looked them up, and by golly they were not codes that allows you to design that way (the way we all do all systems that is)
i'm going home and let this bother me all night... thanks (i cant wait til tomorrow morning when i check my mail) brad -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Jack Carlson Sent: Tuesday, May 05, 2015 4:51 PM To: [email protected] Subject: RE: Light & OH1 Hazard From Same Riser John, You should not have an issue with the design as described. Light and ordinary are commonly mixed, no separate supply main is necessary. Jack W.

The entire ceiling space is an open 14' concrete beams and roof deck, and the mechanical room is separated by sheetrock and self-closing doors. The riser is in the mechanical room and I have 7 upright sprinkler heads fed off the cross main pipe feeding the light hazard office space. What code allows me to design this way or must I create a separate riser feed for each hazard?
