Well Ryan and others- Did some reasearch on the hot topic and here's what I've come up with:
760.61 Applications of Listed PLFA cables
760.61(C) deals with "Other Wiring Within Buildings (obviously used for PLFA) and (3) references cables "specified" in Chapter 3. The only cables I could find in Chapter 3 that are "specified" as suitable for signaling are MC cable- (330.10(A)(2)), MI cable- (332.10(2)) and Tray Cable- (336.10(1)). The only part that seems murky is the limitation of 10 feet. But there is no doubt in my
mind that wiring for a PLFA must be a listed fire alarm cable or one of the three cables I have listed here. I reiterate NO NM cable.
That my story and I'm sticking to it.
