Even with the new language in the supplement as referenced by Steve, the issue is not clear.
The language in the supplement indicates that NFPA 13 is essentially equivalent to section 13.6.8 of ASCE. However, the requirement for 2 in. oversized rings is not in section 13.6.8. It is in section 13.5.6.2.2, and that section still speaks to sprinkler heads thought suspended ceilings needing 2 in. rings. Not that I am an advocate of the 2 in. ring, we haven't really even enforced it yet thinking it was going to go away, but it seems to still be required.

Seismic is still a "brave new world" in the southeast. South Carolina enforces it while Ga typically does not. We work in both states. The S.C. fire marshal stated that he will enforce NFPA 13 not the IBC. So this could be a vendor who is out for a buck or is just flat wrong. Joe C. Powell Pruett Ford & Associates, Inc.

I did an article on this issue in the NFPA Journal (Jan 2005). This issue initiated the first TIA on the 02 edition of 13 and lead to significant changes in the 07 edition. Any one interested that doesn't keep old Journals can get a copy of the article off our web page: http://www.firesprinkler.org/techservices/articles/index.html. This never really had a huge impact on installations since spec's basically simply said per 13 and FM's typically reviewed just 13 (not the IBC). It certainly could have been an issue for any one playing in the consulting world.
