Syston Fire Alarm 14/2, 250 Ft
Product features include versatile applications for fire signaling circuits, smoke detectors, strobes, pull stations, and addressable control systems. The cable uses solid bare copper conductors for maximum conductivity and reliability. It’s designed as FPLP plenum-rated with CMP/CL3P/FT6 flame retardancy, suitable for plenum spaces used for air distribution. This construction emphasizes safety in ceiling or enclosure spaces, where air handling occurs, and aligns with higher flame-retardant standards than standard CMP cable types.
Applications span critical fire safety elements and security components, ensuring robust performance for both new installations and upgrades. The solid copper conductors reduce resistance and improve signal integrity across control and notification circuits. For facilities seeking a durable, UL-ETL listed option with plenum-rated protection, this cable is a strong candidate for 14/2 wiring runs.
Syston 14/2, 500 ft Plenum-CMP Cable
This longer spool version preserves the same core advantages: solid copper conductors for dependable signaling, and a FPLP/CL3P/FT6/PLENUM-rated build designed for air-handling spaces. The cable’s UV resistance adds outdoor versatility, improving performance in exposed or weather-exposed installations while remaining suitable for indoor use. It supports a broad range of fire alarm circuits including voice communications and microprocessor-controlled systems, making it a flexible choice for larger installations or retrofits.
The product’s listing emphasizes UL and ETL listings, reinforcing compliance with safety standards for life-safety wiring. As with the 250 ft version, the plenum-rated construction helps meet building codes where cables traverse air plenums, reducing fire risk in critical pathways. When planning multiple or long runs, this 500 ft option offers cost and labor efficiencies without sacrificing performance.
Syston 14/2, 100 ft Quick Install Cable
This 100 ft version keeps the same solid copper construction and plenum-rated ratings for safe installation in building plenums. It is designed for a variety of signaling and notification roles, including pull stations, audio, and microprocessor-controlled devices. The 100 ft length makes it well-suited for point-to-point runs or shorter segments in complex layouts. The FPLP/PLENUM-CMP/CL3P FT6 rating continues to support high flame resistance and safer ductwork installations, making it a practical option for small projects or remodels where cable routing is constrained.
Syston 14/2 100 ft Low-Voltage Cable
This 100 ft low-voltage cable provides the same high safety standards with solid copper conductors. It carries CMP/CL3P/FT6 plenum-rated construction, suitable for installation in building plenum spaces and air-handling environments. The CMP rating offers a higher flame retardant level than CMR, improving overall fire safety in critical signaling and control circuits. Use cases include fire alarm control wiring, security systems, and public address networks where reliable, durable signaling is required.
EWCS 18 AWG 2/C Fire Alarm Cable
Although lighter gauge than 14 AWG options, this 18 AWG, 2-conductor fire alarm cable is designed for in-wall use with a red PVC jacket. It is made in the USA and features a nominal diameter of approximately 0.155 inches. This makes it suitable for smaller, signaling-specific runs or zones where higher current is not required but reliable signaling remains essential. It complements larger 14/2 systems in mixed-signal environments or retrofits where space and flexibility matter.
Zarivy 14/2 Fire Alarm Cable, 100 ft
Zarivy’s 14/2, 100 ft option emphasizes ease of handling with a red-black pair and a white jacket. While marketed for general low-voltage applications, it notes CL2 rating for in-wall use, aligning with in-wall and some indoor installations. The product highlights copper-clad aluminum usage as a cost and weight-saving measure, which can influence conductor performance versus pure OFC copper. This choice may be suitable for budget-conscious projects where identical signaling needs exist but exact copper purity is flexible.
Voltive 14/2 Riser Cable, 500 ft
Voltive’s 14/2 riser-rated cable uses OFC conductors and a black jacket, designed for in-wall and riser installations with CL3R/CL2 ratings. The 500 ft bulk option supports extended runs and greater project efficiency. Direct burial compatibility adds versatility for certain projects, though typical use remains indoor or ducted pathways between floors. The combination of oxygen-free copper and CL3R/CL2 ratings supports signal integrity and compliance with fire-safety standards in shared spaces and service corridors.
Voltive 14/2 White Direct Burial Cable
The white version offers direct burial capability while maintaining fire-safety credentials with CL2/CL3 ratings and OFC conductors. This makes it suitable for outdoor runs or subterranean pathways where insulation and shielding must withstand environmental exposure. The direct burial designation supports cost-effective exterior installations by eliminating intermediate conduit needs in certain landscapes or exterior signaling networks. As with other Voltive offerings, these cables emphasize reliable signaling and durable construction for life-safety applications.
Buying Guide
Key considerations when selecting 14/2 fire alarm cable includes plenum-rated versus riser-rated versus general purpose ratings. Plenum-rated cables (CMP/PLENUM/FT6) are required for spaces that facilitate air flow, like ceilings and air ducts, to minimize smoke travel and fire risk. Riser-rated (CL3R, CL2) cables are adequate for between floors, while CMP/FT6 or higher ensures the safest installation in building plenums. Copper conductors (OFС) provide consistent conductivity and signal integrity; copper-clad aluminum (CCA) can reduce weight and cost but may exhibit higher resistance over long runs. Always verify UL/ETL listings and compatibility with local codes.
– Cable gauge and conductor count: 14/2 indicates two conductors of 14 AWG; verify compatibility with devices (detectors, pull stations, sirens) and power requirements.
– Plenum versus in-wall suitability: If routing through air-handling spaces, prioritize CMP/PLENUM-rated products.
– Length and installation strategy: Longer runs benefit from spooled options to minimize splicing and maintain signal integrity. For long corridors, a single continuous run with appropriate ratings reduces connection points.
– Environment and exposure: Outdoor or exposed installations may require UV resistance and weather-rated jackets, even for fire alarm signaling.
– Certifications and compatibility: Look for UL/ETL listings and manufacturer guidance to ensure compliance with local fire codes and building standards.
– Installation tips: Plan routes to minimize physical damage, use correct inner and outer jackets, and avoid bridging critical signaling paths with low-quality connectors. For high-occupancy structures, match cable type to segments that carry critical notifications, ensuring redundancy where feasible.
