SYSTON 18/8 Fire Security Burglar Station Sound Alarm Control Cable

Our review of the SYSTON 18/8 control cable finds it best suited to installers and facility electricians who need a reliable, plenum-rated multiconductor for low-voltage safety and communication circuits. The single biggest reason to buy is its combination of stranded bare copper conductors and continuous aluminum foil shielding, which together deliver clear signal transmission for fire alarm, security and intercom runs while meeting CMP plenum fire safety requirements. It is a practical choice when runs must travel through ceilings or air plenums without sacrificing signal integrity.

Key Features

• Plenum rated CMP/CL3P: Allows safe installation in ceiling plenums and air handling spaces where higher flame retardant performance is required.
• Stranded bare copper conductors: Provides reliable conductivity and flexibility for routing through conduit and tight pathways.
• Aluminum foil shielding: Reduces electromagnetic interference so signals for alarms and communications remain clear over longer runs.
• 300V CL3 rating: Suits a wide range of low-voltage, power-limited applications such as access control and thermostats with a solid insulation margin.
• UV resistant jacket: Helps the cable resist degradation in exposed areas where sunlight may reach portions of the run.

Who It's For

The cable is aimed at professional electricians, security system installers and building maintenance teams who run fire alarm, burglar alarm, public address and intercom circuits through commercial or multi-family buildings. Its plenum rating and shielding make it especially useful in environments where air-handling space routing and EMI protection are required.

Home hobbyists doing low-voltage projects in non-plenum spaces may find less need for the CMP rating and could choose a lower-cost alternative. Also, those needing very thick power conductors or mains wiring should look for cable rated for higher voltages.

Pros & Cons

Pros

• Solid shielding performance keeps noise out of sensitive alarm and audio lines.
• Stranded 100% copper conductors balance conductivity with flexibility for easier installation.
• Plenum CMP rating gives high flame retardant protection for ceiling and air-handling spaces.
• Good value for those who need both safety rating and shielding in one cable.

Cons

• Some users note the conductor bundle can feel thin for certain mechanical demands, so protect it where abrasion or strain is expected.

Our Verdict

The SYSTON 18/8 plenum control cable is a practical choice for installers who need dependable shielding and the highest plenum fire-rating for ceiling and air-handling spaces. It delivers clear signal transmission for alarm and communication systems and represents good value where safety and EMI protection are required; those with heavy-duty power needs or non-plenum installs may opt for alternate, lower-cost constructions.
