Alarm Cables for Your Fire Alarm System

Introducing the 16/4 Fire Alarm Cable, featuring PVC insulation housing four 16 gauge solid bare copper conductors. Its CL2R CMR-rated jacket includes a rip cord for seamless separation. Manufactured to NEC guidelines and verified by, this cable is proudly made in America.

During critical moments, prioritize top-tier fire alarm cables from a trusted source. We provide premium products, acknowledging their indispensable role in emergencies. Rely on fire alarm cables to trigger sprinklers and smoke alarms, guaranteeing swift evacuation during fire incidents.

Fire Alarm System Applications

There are many uses for a fire alarm cable such as smoke alarms, smoke detectors, voice communications, microprocessor-controlled systems, pull boxes (fire alarm signals), burglar alarms, and other low-voltage applications. Fire alarm circuits control and power applications such as safety functions, elevator capture and shutdown, door release, and damper control.

Fire Alarm Products

Discover our wide range of shielded and unshielded fire alarm cables, including Plenum, Non-Plenum, and Riser types in FPLP and FPLR configurations. Ranging from 18 AWG to 12 AWG solid bare copper conductors, these cables offer flexibility for effortless installation. Committed to quality and reliability, our cables are ETL-listed and RoHS-compliant.

Opt for Plenum-rated fire cables, designed for installation in the area between floors used as duct areas or other air spaces. The term "Plenum" refers to the material used in the cable jacket, which burns less than non-plenum cables, enhancing safety and reliability.

Plenum vs Riser in Cabling Design - Why Plenum?

A plenum space is an open area above the drop ceiling or below the floor that is used for air circulation in buildings. This could be a problem if there is ever a fire. Using non-plenum cables in a plenum space can spread fire and toxic smoke throughout a building. Plenum cable uses a flame-retardant jacket that is made of special plastics to prevent the release of harmful smoke. Plenum cable is mostly used in commercial applications such as schools and hospital buildings that house a large population of people. It also is required in most multi-floor business buildings with large plenum space areas.

Plenum vs Riser in Cabling Design

1. Plenum-Rated Cable: Plenum cables have a higher fire rating and are designed with a fire-retardant plastic jacket made of either low-smoke PVC or fluorinated ethylene polymer (FEP).

2. Riser-Rated Cable: Riser-rated cables run between floors through cable risers or in elevator shafts in non-plenum areas. These cables must also self-extinguish and prevent the flame from traveling up the cable in a vertical burn test.

3. General Purpose Cable: General Purpose cables have no fire rating. These are not comparable to Riser or Plenum cable jackets because when General-Purpose cables burn they release smoke and toxins, as there are no fire safety aspects to these cables.

Cable Fire Ratings

There are a variety of characteristics to consider when purchasing cable for an installation, from the conductor gauge to the jacketing material. Cable jackets provide mechanical, fire, chemical, and installation protection to the important inner parts of the cable. The effectiveness of their protection depends on the materials from which the jacket is made. There are several categories of jacketing material, each with different fire ratings. The two main and highest-quality jacket types are Plenum and Riser, but there are also General Application and Outdoor cable jackets.
