I need information on requirements for refuge communications/communicators in two story schools. My NFPA
Handbook 2019 p. 711 at the top of the page references Communications Systems for Life Safety in Schools. Also,
ANSI/NEMA Standard SB-40 not to be found. I am a rookie and everything seems to be a maze. I haven't found if the Refuge is even required. Hope someone send me in the right direction.
I get a blank on the SEARCH.
