Keep in mind you won't be able to take the QR design reduction based upon ceiling height unless all the sprinklers in your area are QR.

Go figure. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Matthew J.

I am working on a system for a school where the systems in some existing classrooms are going to be modified and all QR sprinklers are going to be installed. The hydraulic area I plan to use is one classroom of 4-6 sprinklers and two sprinklers in the corridor (meets requirements). The corridor sprinkler are standard response. That wouldn't effect the hydraulics in this situation would it? Todd G.
