Understanding Fire Alarm Cabling

Fire alarm cabling is the backbone of any fire alarm system, serving as the conduit through which signals and power are transmitted between various components, such as smoke detectors, control panels, and notification devices. The integrity and quality of these cables are crucial for ensuring that the fire alarm system functions effectively in an emergency.

Types of Fire Alarm Cables

  1. Non-Power-Limited Fire Alarm Cables (NPLFA):

  • These cables are designed for circuits that do not have power limitations. They are robust and suitable for high-power fire alarm systems.

  1. Power-Limited Fire Alarm Cables (PLFA):

  • These are used in systems where power is limited, ensuring safety and preventing overheating.

  1. FPLR (Fire Power Limited Riser):

  • These cables are designed for vertical riser applications and are fire-resistant, ensuring safety in multi-story buildings.

  1. FPLP (Fire Power Limited Plenum):

  • These cables are used in plenum spaces, such as above drop ceilings, where they must meet strict fire resistance standards.
