Fire alarm cable is, of course, typically used for the wiring of fire alarms, but can also be used to wire other devices like smoke detectors, voice communications, burglar alarms, and in fire protective circuits.
All fire alarm cable is designed to perform in high-heat scenarios, but there are different types of fire alarm cable with their own attributes unique to the situation they’re used in:
FPLP (Plenum Fire Alarm Power-Limited Cable) — Plenum cable is designed to be used in air ducts, or the space between the structural ceiling and a drop-down ceiling. These cables (sometimes referred to as CMP, or Communications Plenum Cable) have insulated jackets made of fire-resistant materials such as polyvinyl chloride (PVC) or fluorinated ethylene polymer (FEP), and are designed to restrict flame propagation to no more than five feet and limit the amount of smoke emitted during a fire. We offer both shielded plenum-rated fire alarm cables and unshielded plenum-rated fire alarm cables.
FPLR (Riser Fire Alarm Power-Limited Cable) — Riser cable is designed for non-plenum environments, mainly in risers or vertical shafts. Riser cables meet the standards for levels of fire resistance installation necessary in a vertical riser, or other non-plenum environments. These cables (sometimes referred to as CMR, or Communications Riser Cable) are flame-retardant, intended to prevent the spread of fire from one floor to another. We offer both shielded riser-rated fire alarm cables and unshielded riser-rated fire alarm cables.
Direct Burial Fire Alarm Cable — We also offer fire alarm cable rated for direct burial. These cables are suitable for outdoor use and indoor trays, allowing a variety of uses for applications like low voltage industrial process control circuits, power-limited circuits, and power-limited fire alarm circuits requring buriable cable. To make these cables rated for direct burial, they feature a PVC jacket that is uniquely sunlight/moisture resistant. We offer fire alarm cable rated for direct-bur
