In the North American market, UL 1424 listing is not optional—it's code. Our FPL Shielded (Plenum) Fire Alarm Cable is engineered specifically to comply with this rigorous standard for cables installed in plenum spaces (air-handling areas above ceilings or in raised floors). For distributors, stocking this cable is your direct pass to participating in lucrative commercial, institutional, and high-rise projects where compliance is strictly enforced by authorities having jurisdiction (AHJs). Here’s why it’s a strategic stock item:
Mandatory for Market Access: This is the only cable permitted for fire alarm installations within plenum spaces per the National Electrical Code (NEC) in the U.S. and the Canadian Electrical Code (CEC). Without it, your contractor customers cannot complete most commercial jobs. You become their essential, code-compliant source.
Shielded Performance Meets Stringent Demands: Unlike standard FPL, our shielded variant (typically FPLP) incorporates a foil shield. This provides crucial protection against electromagnetic interference (EMI) in modern buildings packed with HVAC systems, data cables, and fluorescent lighting, preventing false alarms and ensuring signal clarity for addressable systems.
Circuit Integrity in a Plenum-Rated Package: The cable is constructed to not only meet flame spread and smoke density requirements for plenums but also to maintain circuit integrity during a fire event, ensuring the alarm system remains operational for safe evacuation. This dual performance is a compelling value proposition for system designers.
What does 'FPL' and 'Plenum Rated' specifically mean, and why is it required?
FPL stands for "Fire-Protective Signaling Cable, Limited Power." Plenum Rated means the cable is certified for installation in plenum air-handling spaces without the need for metal conduit, as it meets strict flame spread (≤25) and smoke density (≤50) tests per UL 1424 and NFPA 262 (Steiner Tunnel Test). It is required by the NEC/CEC to prevent the spread of toxic smoke through a building's airflow system in the event of a fire.
When should I specify shielded FPL cable versus unshielded FPL?
Specify shielded FPL cable in any plenum application where the cable run is in close proximity to potential sources of electromagnetic interference. This includes near large motorized equipment (elevators, HVAC units), parallel runs with AC power lines, or in buildings with dense wireless/RF infrastructure. The shield prevents interference from causing nuisance alarms or communication errors in sensitive addressable fire alarm control panels.
How do I verify the UL listing, and what documentation do you provide?
Every reel is marked with the UL listing mark. We provide the official UL File Number (e.g., E123456) upon request. For distributors and contractors, we can supply a UL Product IQ Report or UL Certificate of Compliance, which are often required for project submittals to engineers and building inspectors to prove compliance.
Can this cable be used in risers or other spaces, or is it only for plenums?
While optimized and rated for plenums, UL 1424 FPL cable is also suitable for use in riser (vertical shaft) and general purpose applications according to the NEC. However, a shielded FPLR cable would be the specific listing for riser applications if that is the primary need. Our FPLP provides broad compliance for plenum-centric projects.
Do you offer this cable in different conductor configurations (e.g., 2, 4, 6 conductor) for various fire alarm panel needs?
Yes. We manufacture UL 1424 FPL Shielded Cable in the standard configurations required by the industry, including 2-conductor for basic NAC (Notification Appliance Circuit) loops, 4-conductor, and multi-conductor versions for complex signaling circuits, allowing you to cover all needs for a compliant fire alarm install from one trusted source.
