SYSTON 16/2 Fire Alarm Cable 100 ft
The SYSTON 16/2 cable uses 100% stranded copper conductors designed for low-voltage applications, including fire alarm and security systems. The shielding, an aluminum foil layer, helps reduce EMI and preserves signal integrity in environments with potential interference. This CMP/CL3P shielded construction supports indoor and outdoor use, with UL/ETL listing indicating compliance with safety and performance standards. Applications span fire alarm wiring, security, intercoms, and nurse call systems, making it suitable for building-wide low voltage networks.
18/2 Fire Alarm Cable Shielded (200 ft)
The 18/2 shielded fire alarm cable from Cableague features two solid copper conductors with PVC insulation and CMP/CL3P rating for low-voltage infrastructure. UL-listed and ETL-compliant, it delivers strong electrical conductivity and reliable data transmission critical for door bells, burglar systems, and security stations. The shield helps minimize EMI, ensuring clean signals in dense building environments or near other electrical equipment. Its straightforward two-conductor design simplifies installation for typical alarm panel wiring and sensors.
18/4 Fire Alarm Cable Shielded (200 ft)
The 18/4 shielded fire alarm cable from Cableague uses four conductors with solid copper cores and PVC insulation. Its CMP/CL3P shielded design supports reliable multi-signal wiring for complex alarm, access control, and intercom systems. UL-listed and ETL-compliant, the cable emphasizes excellent electrical conductivity and robust construction for indoor installations, while shielding helps mitigate EMI in shared electrical spaces.
SYSTON 16/4 Fire Alarm Cable 1000 ft
The SYSTON 16/4 cable provides four 16 AWG stranded copper conductors with shielded, CMP/CL3P-rated construction. Designed for indoor/outdoor low-voltage applications, it supports extensive fire alarm and security networks. The shielding combats EMI, preserving signal clarity across longer runs or in electrically noisy environments. UL/ETL listings assure compliance with safety standards, making it a strong choice for larger building deployments and centralized alarm systems.
SYSTON 14/4 Shielded Fire Alarm Cable
The 14/4 Syston cable uses 14 AWG stranded copper conductors for higher current capacity and robust performance in 0-30V low-voltage systems. Shielded CMP/CL3P construction reduces EMI impact on signal transmission, supporting reliable operation for alarm, intercom, and LED dimming control applications. UL/ETL listed, its versatile two-page coverage allows use in both indoor and outdoor settings, including conduit-routed runs and riser installations.
SYSTON 18/4 Riser Shielded Cable
The SYSTON 18/4 riser-rated shielded cable is designed for indoor/outdoor use with 0-30V low-voltage systems. Riser-rated CMP/CL3R construction supports vertical installations between floors and through riser closets, while shielding minimizes EMI interference in densely wired facilities. UL/ETL listed confirms adherence to safety and performance standards, making it suitable for security stations, door bells, and building-wide alarm networks.
Buying Guide
- Conductor count and voltage: Higher conductor counts (e.g., 4-conductor options) support multi-signal alarms and control circuits, while 2-conductor cables suit basic alarm wiring. Verify a CMP/CL3P rating for plenum spaces or CL3R for riser applications.
- Shielding: Aluminum foil shielding helps reduce EMI and ensures clearer signal transmission, especially in buildings with dense electrical infrastructure. Consider shielded cables for security, intercoms, and data transmission alongside alarms.
- Pure copper vs. CCA: Copper conductors offer superior conductivity and reliability, while Copper-Clad Aluminum (CCA) is more budget-friendly but may compromise long-term performance in high-noise environments.
- UL/ETL listings: Listings indicate adherence to safety and performance standards. For critical life-safety systems like fire alarms, select UL-listed and ETL-compliant cables.
- Indoor vs. outdoor and riser suitability: Look for CMP (plenum) or CL3P ratings for indoor and vented spaces, and CMP/CL3R or riser-rated variants for vertical or through-floor installations.
- Installation considerations: Longer runs may require thicker shielding or lower gauge conductors to minimize signal loss. Plan route, consider conduit runs, and account for environmental exposure when selecting cable type.
- Cost vs. performance: While premium shielded copper cables offer reliability, budget-friendly CCA options may suffice for simple, short runs. Match the cable spec to the project’s risk tolerance and performance needs.
Selecting the right stranded fire alarm cable involves balancing conductor design, shielding effectiveness, and compliance with safety standards. For complex systems spanning multiple zones, a four-conductor shielded cable with plenum or riser ratings often delivers robust performance and easier compliance with building codes. Always verify manufacturer specifications and local code requirements before purchasing and installing low-voltage alarm and security cabling.
