1hr ceiling attached to the bottom of the truss and a 1hr floor on top. Truss are normally 16 or 24in OC. No flame retardant material in the truss construction. So far, we have lost jobs in 2 municipalities where the AHJ has accepted this. I have been telling my salesmen that is is not worth the liability to omit these sprinklers and to keep them in our bid.

What is the truss spacing? Are they made with fire retardant lumber? If it doesn't meet any on the exceptions in 8.14, then it should be sprinklered. Are the AHJs accepting this?
