Installing a BDA system and on past projects where a 2-hr rated shaft was not provided we installed phenolic 2-hr rated conduit and the standard BDA cable and have not had a problem. Reading the cut sheet of this conduit it sounds like to achieve the 2-hr rating we would also need to install 2-hr rated cable.

"The conduit shall meet the requirements of NFPA130 and NFPA502. The conduit when installed together with the appropriately matched 2 hour fire-rated cable will meet the requirements of the UL2196 - 2 hour fire-test @ 1850°F (1010°C). The circuits will continue functioning for the duration of the fire-test."

This is a bit confusing to me and wanted to see if someone could explain if 2-hr rated cable would be required. AHJ & Engineer are no help and want to make sure I am installing correctly. I would like to avoid the 2-hr rated cable if possible for the obvious cost.

I only ask because those NFPA sections you quoted are railway standards. If this is an Emergency Responder Communication System, then the standard would be NFPA 1221 and NFPA 72. I could imagine needing 2-hour rated cable for an Emergency Responder System. But if it's just a cellular repeater or internet/cable TV, the only thing that needs to be fire-rated are the penetrations of the floor and corridor walls - a simple fire stopping job that doesn't care about the wires inside the conduits.
