Thanks much Gents!! A Gentleman told me of where the AHJ failed an installation because they used Red Jacketed Cat5/6. I told him I didn't think that violated NEC Code, but that the Locality and AHJ was just mandating it. But I wasn't sure on that.
I know that using fire alarm cable for anything but fire alarms is prohibited. Example, you can't use it for LV door latches or speaker wire. But I know of no restrictions for other class 2 red jacketed cable. Take at look at article 725.
FPL, FPLR, and FPLP can be had in many colors, sizes, and conductor counts. It may be marketed as "fire alarm cable" but it is perfectly suitable for any low voltage installation that don't need CAT5E/6 or something similarly restrictive. Some jurisdictions, and I don't know if LA is one of them, may prohibit the use of red colored cable for anything other than fire but it is not part of any NFPA standard.
