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.
So we can't use conduit and any of the normal building wires for a fire alarm system? If so there are a lot of systems that are in violation, because that is the installation for 90% of the fire alarm systems in this area. Fire alarm cables are not normally used.
