NFPA 497 Military question

Question asked by scott.shipton on Jul 12, 2019


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,
