Buying Guide: Direct Burial Fire Alarm Cable Buyer’s Checklist
- Conductor arrangement: Determine needed conductor count (2, 4, or more) based on the number of devices and circuits.
- Voltage rating and safety certifications: Look for CL2/CL3P, CMP/FT6, or UL listings to ensure safe in-wall, in-ceiling, and direct burial use.
- Plenum vs. non-plenum: For spaces that carry air, prefer plenum-rated CMP/FT6 cables to minimize fire risk and comply with building codes.
- Outdoor durability: Choose UV- and weather-resistant jackets for exposed runs; direct burial-ready cables save conduit costs.
- Conductor material: Pure copper offers better conductivity than copper-clad aluminum (CCA); solid conductors can reduce resistance over longer runs.
- Flexibility vs. distance: Thinner gauges (like 22 AWG) are suited for signaling over longer runs, while heavier gauges support higher current needs.
- Installation environment: For underground installs, ensure direct burial capability; for in-wall runs, verify safe in-wall ratings and required certifications.
- Brand and warranty: Reputable brands with documented specs and warranties reduce risk on critical life-safety installations.
- Cost vs. future-proofing: While initial cost matters, selecting cables with appropriate ratings and conductor counts can save retrofit expenses later.
