Default Residential basement smoke detectors

If a support beam is more than eight inches in depth. Is it required to have a smoke on each side of support beam?

I'm having the same issue. I think it might be in the NFPA fire alarm book. I'm pretty sure it needs one I wish I someone was able to verify it.

That would be in NFPA 72...as I recall it was 12" before it created a new space that required its own smoke detector.
