Unenclosed stairway and draft curtain

arch_06 said:
It's interesting that IBC 2012 changed the language so that only escalator openings of certain size require the draft curtain and closely spaced sprinklers. I don't think MA has adopted IBC 2012 yet, but I would have complied with 712.1.8.Any manufacturer/model suggestions on the fire alarm activated drop-down draft curtains? Does NFPA approve of such products for draft curtain use?

? If I understand your comment about the draft curtain for stairs it was reorganized to Section 1009.3 Stairways in 2012.

dont think nfpa approves stuff, either meet the prescriptive of the code, or some type of testing like UL.
