Syston Fire Alarm Cable 16/2 1000 Ft
Summary: Pure copper conductors, unshielded 16 AWG, and a CMP/CL3P/FT6 plenum-rated jacket make this suitable for long runs inside ceilings and plenums. Best for large buildings or campuses needing robust signaling circuits, call points, and addressable systems. Caution: outdoor exposure is acceptable but ensure weather conditions align with listed ratings.
EWCS 18 AWG 2/C FPLR Shielded Fire Alarm Cable
Summary: Two solid copper conductors, shielded with an aluminum Mylar layer, and a red PVC jacket. Best for indoor or between-floor runs where EMI could affect signaling. Caution: not intended for outdoor direct burial; keep within approved riser or plenum pathways as specified.
Vertical Cable Fire Alarm Cable, 22 AWG, 4 Conductor
Summary: 22 AWG, four-conductor, FPLR-rated with solid bare copper conductors. Best for medium-length, non-plenum indoor runs where UV resistance is beneficial. Caution: thinner conductor size means lower current capacity; plan for compatible devices and power needs.
KWANGIL 16AWG 2/C Shielded Fire Alarm Cable
Summary: High-temperature capable shielded FPL cable with 16 AWG conductors and UL/cUL/CE certification. Best for EMI-prone environments and indoor-outdoor installations where shielding improves signal integrity. Caution: ensure jacket and shield compatibility with local code requirements and temperature ranges.
Syston Fire Alarm Cable 14/2 500 Ft
Summary: 14/2 configuration in 500 ft spools, solid copper conductors, and FPLP/CL3P/FT6 plenum-rated jacket. Best for large, complex installations requiring longer plenum runs and multiple signaling paths. Caution: larger gauge difference may require adaptors or re-sizing terminations for some devices.
Buying Guide
What matters most when choosing fire alarm cables? Consider these practical factors:
- Jacket rating: Plenum-rated (CMP/FT6) is required for spaces with air handling; non-plenum spaces can use CMR/CM as allowed by code.
- Conductor size and count: Higher gauge (lower number) supports longer runs and higher current; more conductors support multi‑point signaling and addressable systems.
- Shielding: Shielded cables reduce EMI in data-heavy or interference-prone environments; indoor-only installs may not need shielding.
- UL/ETL listings and NFPA alignment: Ensure cables meet local fire alarm and life safety code requirements for your building type.
- Environment and placement: Outdoor exposure, UV resistance, and temperature ratings influence jacket material and wiring type.
- Installation practicalities: Length on spools, ease of stripping (rip cords), and labeling affect on-site efficiency.
FAQ
- What is the difference between FPLP and FPLR in fire alarm cables?
FPLP (Plenum-rated) is designed for spaces that distribute air, like drop ceilings. FPLR (Riser-rated) is intended for between-floor runs. Both meet fire safety requirements, but placement dictates which rating is required.
- Should I use shielded or unshielded fire alarm cable?
Shielded cables reduce EMI and improve signal clarity in noisy electrical environments. If running near high‑power lines or data lines, shielded cable is preferable; otherwise, unshielded may suffice.
- Can I run fire alarm cable outdoors?
Yes, if the jacket is rated for outdoor exposure and the installation complies with applicable codes. Many products shown are indoor/outdoor rated but always verify local requirements.
- What conductor size is best for long fire alarm runs?
Long runs benefit from larger conductors (e.g., 16 AWG or 14 AWG) to maintain signal integrity and reduce voltage drop. Choose based on device requirements and circuit length.
- Do I need UL or ETL listings for my cables?
Yes. UL or ETL listings indicate compliance with recognized safety standards for life-safety systems. Verify with local authorities or the project specifications.
- How do I determine the right number of conductors?
Assess the system: basic supervision may need fewer conductors, while addressable or multi-point systems require additional conductors for signaling, power, and control paths.
