SYSTON 18/2 Fire Security Burglar Station Control Cable - Plenum CMP

Our review of the SYSTON 18/2 Fire Security Burglar Station control cable finds it best suited for installers and technicians who need a reliable, plenum-rated, shielded control cable for low-voltage systems. The single biggest reason to choose this cable is its combination of stranded pure copper conductors and aluminum foil shielding inside a CMP/CL3P jacket, which delivers clear signal transmission and suitable flame retardant performance for plenum spaces. For projects that require a 300V, CL3-rated, power-limited cable with UV resistance for indoor or protected outdoor runs, this cable is a practical choice.

Key Features

• Plenum-rated CMP: The CMP/CL3P/FT6 flame retardant jacket allows safe use in building plenum spaces where air distribution requires higher fire performance.
• Stranded pure copper: Stranded bare copper conductors provide consistent conductivity and flexibility for pull-throughs and terminations in control and alarm systems.
• Aluminum foil shield: The foil shielding blocks electromagnetic interference to keep low-voltage signals clear for security, intercoms, and communications equipment.
• 300V CL3 rating: The 300V insulation and Class 3 power-limited rating suit thermostats, access control, and other low-voltage circuits with a safety margin.
• Multiple application support: Designed for fire alarm, burglar alarm, public address, telephone stations, nurse call and other power-limited installations where signal integrity matters.

Who It's For

This cable is aimed at professional electricians, low-voltage contractors, facility maintenance teams, and advanced DIYers installing or upgrading fire alarm, security, intercom, PA, and instrument wiring in commercial or multi-family buildings. It is especially relevant where runs pass through ceilings or plenums and require CMP-rated materials.

Those who only need basic residential speaker wire or non-plenum general purpose wiring can look elsewhere to save cost; this cables plenum construction and shielding add value specifically where code or EMI concerns exist.

Pros & Cons

Pros

• Good shielding performance preserves signal clarity in environments with potential EMI.
• Stranded pure copper conductors are flexible and reliable for installation and termination.
• Plenum-rated CMP construction meets higher fire safety needs for ceiling and air-handling spaces.

Cons

• Some customers describe the jacket thickness as thin, so it may require care during pulling or in exposed runs.

Our Verdict

The SYSTON 18/2 control cable is a solid, cost-effective option for professionals and facility teams needing a plenum-rated, shielded, pure copper cable for low-voltage, power-limited systems. It offers clear shielding, flexibility, and the higher flame retardant performance required in air-handling plenums, making it good value where code compliance and signal integrity are priorities.

Frequently Asked Questions

Is this cable suitable for plenum spaces?
Yes. It is CMP/CL3P/FT6 plenum rated for use in building air-handling spaces.

Can it be used outdoors?
It is UV resistant and suitable for protected outdoor low-voltage applications, but install in protected conduits where required by code.

Does the shield prevent interference?
The aluminum foil shield reduces EMI and helps preserve signal clarity for communications and alarm circuits.
