West Penn Wire 980RD — 18 AWG 2 Conductor FPLR Fire Alarm Cable

The West Penn Wire 980RD uses solid 18 AWG bare copper conductors with an unshielded FPLR jacket and an overall jacket layer. Rated up to 300 volts, this cable is designed for fire alarm circuits where a reliable, straightforward conductor path is essential. The solid conductors reduce resistance and improve signal integrity for point-to-point signaling across short to moderate runs.
Key considerations include its non-plenum rating, limiting its use to non-plenum spaces, and its USA-made construction. It is a good fit for interior walls and cable trays where reduced complexity and a straightforward installation are prioritized. The unshielded design minimizes EMI concerns in typical office or commercial environments, where electromagnetic interference is less likely to impact basic alarm signaling.
EWCS 18 AWG 2/C Solid FPLR Riser Rated Shielded Fire Alarm Cable

This EWCS cable is UL-listed for FPLR use and designed for riser installations between floors, including non-plenum spaces. It features two solid copper conductors with a shield (aluminum Mylar) and a drain wire for EMI protection and signal clarity. A red PVC jacket identifies the circuit, and a rip cord aids stripping. Rated at 300 volts and 75°C, it balances durability with ease of installation in vertical riser pathways.
Considerations include the shielded design to mitigate EMI in dense electrical environments and the red jacket for easy identification. The riser rating suits multi-story buildings; however, it is not intended for outdoor or direct burial use.
Syston Fire Alarm Security Burglar Station Wire Cable — 14/2 Plenum-Rated

This Syston 14/2 cable is designed for a wide range of security and signaling applications, including fire alarm circuits and voice communications. Pure copper conductors ensure good conductivity, while FPLP/PLenum-rated insulation provides superior fire retardancy for plenum spaces. It is UL and/or ETL listed, making it a compliant choice for building codes and modern safety systems in indoor environments with air distribution systems.
The 14/2 configuration supports typical two-conductor signaling needs, though run length and distance considerations should align with NEC guidelines. Plenum-rated jackets add a layer of safety for air-handling spaces, but installers should confirm compatibility with local code requirements and the specific alarm panel’s needs.
Syston Fire Alarm Security Burglar Station Wire Cable — 18/2 Plenum-Rated

The 18/2 version from Syston offers two solid copper conductors with a plenum-rated shield-free design suitable for indoor use. It carries the CMP/CL3P/FT6 ratings, ensuring flame retardance in air-duct or ceiling plenum spaces. This cable comes with a thin orange/red jacket variant for quick identification and a 300-volt, 75°C rating for robust performance under typical building automation scenarios.
With a focus on reliability in signaling circuits and ease of installation, this cable is a common choice where multiple devices like detectors and pull stations connect to a centralized alarm panel. Plenum-rated insulation helps meet stringent safety requirements in modern commercial buildings.
EWCS 18 AWG 2/C Solid FPLR Riser Rated Shielded Fire Alarm Cable Red

EWCS’s red jacketed FPLR riser-rated cable combines two solid copper conductors with shielding and a robust jacket suitable for vertical runs between floors. The 300-volt rating and 75°C rating align with common fire alarm installations in commercial environments. The red jacket provides quick circuit identification during installation and maintenance tasks.
Key considerations include proper shield usage, as shielded cables help minimize EMI in dense electrical environments. The riser rating makes this cable well-suited for multi-story installations but not for direct outdoor exposure or wet locations. Ensure the chosen length matches the building layout and the fire alarm panel’s input requirements.
Buying Guide
Key purchase considerations to help compare options:
- Jacket rating and location: Choose FPLR for non-plenum and FPLP/PLenum for air-handling spaces. Plenum-rated cables provide extra fire retardance in ceilings and ducts.
- Conductor type and size: Solid copper conductors offer lower resistance and better reliability for signaling; common sizes include 14 AWG and 18 AWG depending on circuit length and load.
- Shielding: Shielded cables reduce EMI, beneficial in electrically noisy environments or when long cable runs cross other power lines.
- Voltage and temperature ratings: Look for 300V and 75°C ratings as common benchmarks for typical fire alarm systems.
- Listings and certifications: UL/ETL listings indicate compliance with safety standards; ensure compatibility with NEC/Local codes and the alarm panel specifications.
- Physical features: Red jackets aid identification; rip cords speed jacket stripping; spool dimensions and marking aid long installations.
- Indoor vs outdoor suitability: Only select cables rated for indoor use unless the installation explicitly requires weatherproof or direct burial options.
- Length and labeling: Spool length markings help monitor remaining cable and plan future expansions without re-spooling.
In practice, select a cable that aligns with both your building’s environmental conditions and the fire alarm system’s wiring diagram. For plenum spaces, favor plenum-rated options (CMP/CL3P/FT6). For simple interior runs, standard FPLR or FPLP options may suffice, provided local codes permit their use. Always verify the installation’s requirements with the system designer or a licensed electrician to ensure safe and compliant operation.
