Syston 18/8 Low Voltage Security Alarm Cable 100 ft - Riser Rated

Our review of this Syston 18/8 low voltage security cable finds it well suited for installers and DIYers who need a reliable, multi-conductor cable for power-limited systems. The single biggest reason to buy is the combination of stranded bare copper conductors and a CMR/CL3R riser-rated jacket, which together deliver dependable conductivity and enhanced flame retardance for commercial or residential runs. It reads as a practical choice when safety certifications and easy handling matter more than decorative flexibility.

Key Features

• Multiple Applications: Works for fire alarm, security, intercoms, access control, nurse call and other low-voltage circuits so one cable can service many system types.
• Pure Copper Conductors: Stranded bare copper conductors provide strong conductivity and flexibility for reliable signal and low-voltage power delivery.
• Riser-Rated Jacket: The CMR/CL3R/FT4 flame-retardant rating improves safety for vertical and riser installations in commercial settings.
• 300V Insulation: A 300V rating and CL3 classification give a generous safety margin for Class 3 power-limited applications like thermostats and security panels.
• Standards Compliance: Meets NEC 725 & 800, UL 13 & 444, UL 1666 and CSA FT4 standards, offering verifiable compliance for code-conscious projects.
• Outdoor Use Ready: UV-resistant and suitable for indoor/outdoor runs where sunlight exposure or harsher conditions may occur.

Who It's For

This cable is aimed at electricians, low-voltage technicians, and homeowners installing or upgrading security, alarm and communications systems who need a riser-rated, multi-conductor option. It is particularly useful on jobs that demand compliance with UL and NEC requirements and where stranded copper conductors are preferred for ease of routing and termination.

Those who need individually shielded pairs or highly thick-gauge power conductors for heavy current runs should look elsewhere; this product targets signal and power-limited circuits rather than high-current power distribution or shield-critical audio installations.

Pros & Cons

Pros

• Stranded bare copper offers good conductivity and flexibility for tight runs and clean terminations.
• CMR/CL3R riser rating and multiple UL/CSA standards make it appropriate for commercial installations.
• Versatile for many applications including fire alarm, intercom, access control and PA systems.
• UV resistance and outdoor suitability add installation flexibility.

Cons

• Some users report the cable feels thinner than expected, so it may not suit projects needing thicker insulation or heavy shielding.

Our Verdict

The Syston 18/8 riser-rated cable is a practical, code-friendly choice for low-voltage security, alarm and communications work where reliable conductivity and flame retardance matter. It offers clear value for installers who need a versatile, standards-compliant multi-conductor cable, though projects requiring heavier insulation or individual pair shielding should consider alternatives.

Frequently Asked Questions

Is this cable suitable for outdoor use?
Yes. The jacket is UV resistant and rated for indoor/outdoor use on runs that do not require burial without additional conduit.

Can this cable be used for fire alarm systems?
Yes. It is specified for fire alarm and other power-limited applications and meets relevant NEC and UL standards for such use.

Does this product include shielding for each pair?
No. The cable is unshielded with stranded bare copper conductors, so select a shielded variant if pair shielding is required.
