I have a balanced pressure system. What confused me was that 5.13 is about supervision not testing. I got in touch with the manufacture and they felt it would only be necessary to test the 4 head flow since the proportioners typically have trouble getting the correct mix at low flows.

System test connections shall be sized to accommodate both the low flow of the proportioner and the maximum anticipated flow through the proportioner.(Also see A5.14) Then some special requirements appear in chapter 8 8.4.1.4.4 For balanced pressure and positive pressure proportioning systems, flow tests shall be permitted to be conducted through the test connections required in Section 5.13. For other proportioning system types, full-flow testing of system and discharge devices is required to properly evaluate the proportioning system. So the answer is generally yes, but if your system is not a balanced or positive pressure proportioning system full flow testing is required, I'm guessing thru the system? Anyone out there on the 16 committee? Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

Does it only have to satisfy the minimum flow of the 4 most remote sprinklers or does it also have accommodate the anticipated maximum flow through the proportioner?
