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).
