Fire Alarm Cable support

[eatapeach]

Does the NFPA 72 provide support distance of J hooks for Fire Alarm cable? NFPA 70 provides a support distance for everything except Fire Alarm cable. The manufacture states not to exceed 5' however most cables in the NFPA 70 require a maximum distance of 4'

NFPA 70 has the requirements for cable supports. The NEC does not distinguish supports of fire alarm cable vs other systems so j-hooks or whatever supports are used are regulated by NFPA 70 not NFPA 72.

Typical spacing for cable or conduit supports is 10-ft, but not everything. For instance, MC Cable whips are limited to a max of 6-ft (if I'm remembering correctly).
