How do I know what kind of fire alarm cable I need?

Fire alarm cables are placed into three broad categories: plenum, non-plenum, and riser. Each of these corresponds to another standardized category. Plenum cable, to be used in ducts or other enclosed air spaces, is called FPLP; non-plenum cable, to be used in applications such as surface wiring, is FPL; and riser cable, which can be used in applications that go vertically from floor to floor, is FPLR. All of these names reflect where the fire alarm cable can be installed safely. Once you know where you will install the cable, you know in which category to start looking.
