ent, (smurf) in houses

[bark]

I'm wiring my son's house and he's decided to put a pretty advanced communication system throughout the house. I'd like to rum some smurf (ent) from the patch panels to the crawl space and the 2nd story attic. The way I read article 362 is it would be fine unless over 3 stories. It's wood framed construction with 1/2" sheetrock. I'm thinks a 15 minute fire rating. Any opinions/help would be appreciated.
Thanks

Keep an eye on temp limits in the attic.
About 10 years ago we had a guy from Chicago if I recall correctly whom wanted his entire new house wired in "PIPE" no cable allowed.
We compromised on "All raceways" ENT and FMC as well as EMT. The thing was the blue ENT we got had a temp limit of around 50C so I ended up using mostly EMT and FMC. I was surprised how easy it is to run EMT in wood residential construction if you think it thru. I wish I had a smart phone then, when it was done the local building department asked us for permission to hold a training there as the "residential only" electrical inspectors were baffled.

That's pretty funny. They do houses like that I heard in Chicago, although I just talked to an electrician from there and he said you don't have to do that anymore. Maybe someone from Chicago can clarify. Thr "resi only" inspector has a lot to look at in that house. Conduit supports, conduit fill, ground tails. Did they make you pull orange thhn for #10, yellow for #12?
