Plenum Cable

When it comes to fire safety, the objective of installers and contractors is to protect life and property. As contractors and installers, we do this by restricting the spread of smoke and minimizing the sources of ignition and combustibility within the hair handling systems. The use of a plenum cable is the best way to accomplish this.

Below you will find information on Networking Plenum, Coaxial Plenum, and Security Alarm Plenum.

Air handling systems such as plenum spaces, air ducts, and ventilation shafts, are great places for fire to spread and smoke to build. Depending on your job, codes may require that cable be designed with specific material in order that they be non-combustible and produce a low amount of toxins and smoke. An example is NFPA 90A Section 4.3.10.2 where materials that are exposed to environmental airflow must be non-combustible, limited-combustible, and/or have a limited flame spread index. This code also designates that the smoke-developed index not exceed a certain amount (in this case 50). NFPA is not the only code that requires this. The NEC, the IMC, and the UMC all include requirements for cabling installed in plenum and airflow spaces.

How do we know whether a cable is plenum rated? Underwriters Laboratories (UL) sets the industry standard for plenum cable. Through rigorous testing, UL certifies cable as CMP that is suitable in plenum spaces. If your job requires plenum cable be sure to get cable with the UL marking on it.

For non-plenum required jobs, CyberXLink carries a fire-retardant cat5E and cat6 cable that is much less expensive while giving you the benefit of fire safety.

While local building codes determine the exact material that must be used in certain spaces, most abide by NFPA codes. Plenum cables fall under NFPA-262—the equivalent of UL-910 standard. These standards require low burn properties and low smoke density. Other tests include UL 723, which tests for surface burning characteristics of building material; UL 2043, which tests for fire heat and visible smoke release for “discrete products” and their accessories;” and UL 1424, which tests power-limited cables for flame travel in plenum spaces.

As cabling contractors, you will run into requests for plenum rated cable. The reason being is that cable presents a fire hazard into the building. Cable and wire can serve as a pathway for fire to travel as well as releasing hazardous toxins and smoke into the atmosphere. In areas where environmental airflow occurs (plenum spaces), fire is fueled by the airflow, increasing the risk of fire spread. For this reason, plenum cable has a jacket designed to self-extinguish and produce a low amount of toxins and smoke upon burning.

For highest fire safety, it is best to assume all drop-ceilings are plenums, whether or not they are officially designated as one. Ductwork disconnection can also occur due to building damage, adverse environmental factors, or simply negligence. Be sure to get plenum cable if there is any question about fire safety.
