Introduction

In the world of fire alarm systems, cable selection is crucial for safety and functionality. Two of the most commonly used cable types are FPLR (Fire Power Limited Riser) and FPLP (Fire Power Limited Plenum) cables. This article provides an authoritative examination of the differences between these cables, with a focus on their applications, specifications, and compliance with fire safety standards.

Definitions of FPLR and FPLP Cables

fplr cable

FPLR cables are designed for vertical spaces known as risers. They are engineered to prevent fire from traveling up the cable, thus limiting the propagation of flames to ensure better fire safety within buildings. FPLR cables are tested per UL 1666, which requires that the cables limit flame spread to 12 feet and not exceed an optical smoke density of 0.5.

FPLP Cable

FPLP cables are intended for plenum spaces, which are areas used for air circulation in heating and air-conditioning systems. These cables meet stringent fire-retardant standards and must be tested to UL 910, demonstrating a maximum flame spread of 5 feet and an optical smoke density of less than 0.5.

Key Differences Between FPLR and FPLP Cables

  • Fire Safety Standards: FPLR cables adhere to UL 1666, while FPLP cables must comply with UL 910.
  • Applications: FPLR cables are used in risers, whereas FPLP cables are suitable for plenum spaces due to their superior fire-resistant properties.
  • Flame Spread Limitation: FPLR cables restrict flame spread to 12 feet, whereas FPLP cables limit it to 5 feet.
  • Optical Smoke Density: Both types require an optical smoke density of less than 0.5, but FPLP cables are subject to more rigorous testing because plenum spaces are essential for air circulation.
  • Cost: Due to enhanced safety features, FPLP cables are generally more expensive than FPLR cables.
