These options cover a range of installations—from compact 100-foot runs to long 1000-foot spools—while maintaining essential safety standards for fire alarm signaling and control circuits. They emphasize solid copper conductors, plenum ratings, and compliance with plenum spaces and air distribution environments found in many facilities. Read on to see how each product stacks up for different building codes and installation needs.
Syston 18/2 Fire Alarm Wire (100 ft)
The 18/2 Syston fire alarm cable uses pure copper conductors for reliable signaling across a range of devices, including smoke detectors, strobes, pull stations, and control circuits. Its FPLP/plenum-rated construction supports safe operation in ceiling plenums and air-handling spaces. Suitable for indoor and outdoor use, this 2-conductor cable aligns with common fire protection system layouts and addressable control networks, offering solid conductivity and robust environmental resistance.
Syston 16/2 Plenum Fire Alarm Wire (1000 ft)
This 16 AWG two-conductor cable provides greater current-carrying capacity for higher-power signaling and longer runs. Its solid copper conductors deliver improved conductivity for addressable and non-addressable fire alarm circuits. The FPLP/PLENUM-RATED design ensures compliance in plenum spaces, with UL/ETL listing that supports building safety codes. Ideal for larger facilities seeking extended spool lengths without sacrificing performance.
Syston 14/2 Fire Alarm Cable (250 ft)
With 14 AWG conductors, this option supports higher current demand for more demanding fire protection systems. The 2-conductor configuration remains easy to install, while the FPLP/plenum-rated construction provides safe usage in air-handling spaces. Its UL/ETL listing confirms compliance with critical fire safety standards, making it suitable for medium-length runs in commercial environments and robust signaling networks.
West Penn 980RD 18 AWG Fire Alarm Cable (100 ft)
This 18 AWG, 2-conductor FPLR cable uses a solid bare copper construction and delivers dependable signaling for fire alarm circuits. Although marketed as non-plenum, its solid copper makeup and overall jacket offer reliable performance for non-plenum installations, with a 300-volt rating. It suits indoor runs where fire alarm devices, notification circuits, and control wires require consistent conductivity.
EWCS 18 AWG Shielded FPLR Fire Alarm Cable (500 ft)
EWCS presents a shielded version of 18 AWG fire alarm cable with FPLR/Riser-rated construction. The shield helps reduce interference in noisy environments, making it suitable for complex systems with multiple signaling lines or data transmission alongside alarm controls. The red jacket and shielded design provide added protection for indoor runs, while UL-listed credentials support regulatory compliance for fire protection installations.
Buying Guide: Fire Alarm Cable Purchase Considerations
When selecting CI cable for a fire alarm system, consider the following factors to balance safety, code compliance, and installation practicality:
- Plenum vs non-plenum: Plenum-rated cables (CMP/CL3P/FT6) are required for air-handling spaces. Non-plenum designs may be adequate for non-duct areas but must align with local codes.
- Conductor size and current needs: Larger gauge (e.g., 14 AWG) offers higher current capacity for power-heavy signaling and longer runs, while 18 AWG is common for standard signaling. Evaluate the number of devices and signaling requirements.
- Shielding: Shielded options reduce electromagnetic interference, beneficial in environments with motors, radios, or dense wiring. Weigh shielding against cost and install complexity.
- UL/ETL listing and compliance: Confirm that cables carry recognized listings for fire alarm applications and match the building code requirements in your jurisdiction.
- Jacket material and outdoor use: For indoor/outdoor applications, UV resistance and jacket durability matter. Some cables are designed specifically for indoor use, others are suited for outdoor exposure.
- Length and spool availability: Long runs reduce splicing but may require careful handling. Ensure spool length aligns with project scope to minimize wastage.
- Color coding and identification: Distinct conductors help differentiate signaling lines, control connections, and addressable circuits during installation and maintenance.
- Environmental and code considerations: Temperature rating, rain exposure, and building occupancy influence cable choice. Always verify compatibility with local fire protection codes and the National Electrical Code (NEC).
- Ease of installation: Copper purity, tensile strength, and flexibility affect pull-phase work, redundancy planning, and future upgrades in complex facilities.
In summary, choosing the right fire alarm CI cable involves balancing plenum safety, conductor size, shielding needs, and regulatory compliance. The five products above provide varied gauges, lengths, and ratings to fit common building layouts while supporting reliable signaling and early-warning performance in safety-critical systems.
