Ok, l am working on a project that requires exit devices for the following:
Reference NFPA 497 (2012 Edition)
All three and all three floors and stairs: Class I, Div. 2, Group D (NEMA 7), Class II, Div. 2, Group G (NEMA 9)
Area Classification (Intrinsically safe: An apparatus/equipment in which all the circuits in which any spark or thermal effect is incapable of causing ignition of a mixture of flammable or combustible material in air under prescribed test conditions as described in ANSI/UL 913 Edition 8. Enclosure Type)
However, l can’t find an exit device anywhere in the world that meets these standards. Does anyone have an idea for me as the spec consultant?
Thanks in advance,
