SYSTON 18/8 Shielded Control Cable 18 AWG 8 Conductors - Plenum Rated

Our review of the SYSTON 18/8 Fire Security Burglar Station Sound Alarm Control Cable finds it best suited to installers and technicians who need a reliable, low-voltage control cable for fire alarm, security and communications wiring. The single biggest reason to buy is its combination of stranded pure copper conductors and full aluminum foil shielding, which together deliver clear signal transmission and ease of handling for power-limited circuits in commercial or residential systems.

Key Features

• Multiple application compatibility: Works for fire alarm, burglar alarm, intercoms, public address, telephone stations and other low-voltage, power-limited wiring needs, reducing the need to stock multiple cable types.
• Pure copper conductors: Stranded bare copper delivers consistent conductivity and flexibility, making routing through conduits and terminations easier and more reliable.
• Aluminum foil shielding: Full foil shield guards against electromagnetic interference so signals remain clear for communication and control circuits.
• Plenum rated CMP/CL3P: Highest flame retardant grade allows installation in plenum spaces such as ceiling air plenums where safer fire performance is required.
• 300V CL3 rating: Designed for 300V low-voltage circuits and Class 3 power-limited applications, suitable for thermostats, access control and audio installations.

Who It's For

Electricians, security system installers and facility maintenance teams will appreciate this cable when they need a plenum-rated, shielded solution for building control wiring. It is particularly useful where EMI protection matters, for example near fluorescent lighting, motors or other noisy electrical equipment.

Those looking for heavy-gauge power wiring or multi-pair data cable for high-speed ethernet should look elsewhere; this product is optimized for low-voltage control, alarm and communication circuits rather than mains power or high-bandwidth network cabling.

Pros & Cons

Pros

• Good wire quality with stranded pure copper that is easy to terminate and flexible during installation.
• Effective shielding performance from the aluminum foil helps maintain signal integrity in noisy environments.
• Plenum-rated CMP/CL3P construction provides safer fire performance for ceiling and air-handling spaces.
• Reasonable value and straightforward dispensing with minimal tangling, according to customers.

Cons

• Some users describe the cable as thinner than expected for 18 AWG bundles, which may matter where a stiffer cable is preferred.
• Limited to low-voltage, power-limited applications and not intended for general power distribution or network backbone use.

Specifications

Our Verdict

The SYSTON 18/8 shielded control cable is a practical choice for professionals needing a plenum-rated, EMI-resistant cable for fire alarm, security and other low-voltage control circuits. Its copper conductors and foil shielding provide reliable performance and good value for power-limited wiring, though those wanting heavier feel or high-bandwidth data capability should consider specialized alternatives.

Frequently Asked Questions
