In NFPA 72, does Pathway Survivability apply only to Emergency Communication systems?
In the 2019 Edition of NFPA 72, Section 12.4 stipulates required protection regarding various levels. Section 24.3 Pathway Survivability defines requirements for different levels of declaration. Chapter 12 applies for all fire alarm wiring.
However, the title of Chapter 24 is for Emergency Communication systems. Does pathway survivability apply only for Emergency Communication systems only?
Thanks in advance.
