Article 330 doesn't apply unless 760 says it does. No manufacturer that I'm aware of offers any guidance other than the generic "comply with all AHJ requirements"; in other words, useless.It depends on the wiring method, if the cable is an MC type then the support requirements of Art 330 would apply. If it is a nonmetallic type cable you may have to reffer to the manufacturers installation instructions.
Away from my code book right now, but IIRC there is a little section in 760 that exempts power limited fire alarm circuits from the necessity of following Chapter 3 unless specfically called for elsewhere in 760.Why would Article 330 not apply?
90.3 seems to state otherwise
Just when I think I'm the thickest plank in the stack, someone makes me feel better about myself! :lol::lol:LOL I just googled it and saw that :lol: Here I am thinking it is some sort of code or standard.
