A power-limited fire alarm cable that can be used in plenum is marked as_____?

Explanation:
Plenum spaces require cables with a jacket and design that limit smoke and flame spread. The marking FPLP shows a power-limited fire alarm cable that is specifically rated for use in plenums. The “P” indicates plenum rating, while the base “FPL” identifies a power-limited fire alarm cable. In contrast, CMP stands for plenum-rated communications cable (used for data, not power-limited fire alarms), and CMR stands for riser-rated communications cable. A cable marked FPL is power-limited but not necessarily suitable for plenum spaces. So the designation that confirms a power-limited fire alarm cable is approved for plenum use is the FPLP marking.
