If you don’t have a crawl space or attic with access, and aren’t somewhere they run conduit for resi, then most probably yes.

Is that the Great White one? The horrors. I am haunted by that footage. Like Dante’s inferno brought to life in the flesh. We watched it in my apprenticeship. That and the fire in the MGM grand. Needless to say I took my fire alarm installs very seriously when most don’t. I never want any systems I touched to fail.
