SYSTON 18/2 Fire Security Burglar Station Sound Alarm Control Cable is

Our review of the SYSTON 18/2 control cable finds it best suited for installers and facility technicians who need a reliable, plenum-rated low-voltage cable for alarm, intercom and access control wiring; the single biggest reason to buy is its combination of CMP plenum rating and full aluminum foil shielding, which together protect signals in ceiling plenum spaces while meeting strict flame-retardant requirements. The review examines real-world handling, shielding performance and where this cable fits among other low-voltage wiring choices.

Key Features

• Multiple application compatibility: Works for fire alarm, burglar station, public address, intercom, telephone and other power-limited low-voltage circuits, making it a versatile choice for building wiring projects.
• Pure copper conductors: Stranded bare copper conductors provide consistent conductivity and flexibility for routing through tight spaces and conduit runs.
• Aluminum foil shielding: A wraparound shield reduces electromagnetic interference so audio and communication signals stay clear in noisy electrical environments.
• CMP plenum rating: The plenum-rated CMP/CL3P/FT6 construction allows installation in plenum airspaces where higher flame retardance is required.
• 300V CL3 rating: Suitable for 300V low-voltage, power-limited applications such as thermostats, security systems and A/V installations.

Who It's For

This cable suits professional electricians, low-voltage contractors and maintenance teams who need a plenum-rated, shielded control cable for buildings with air-handling plenum spaces. It is practical for wiring fire and security systems where EMI protection and compliance with stricter flame tests are required.

Home DIYers who do not need plenum-rated cable or who require thicker conductors for higher mechanical robustness may want to consider standard CMR or CM cables instead; likewise, projects that demand heavier gauge wire for power distribution are outside this cable's intended use.

Pros & Cons

Pros

• Reliable conductivity from stranded bare copper that is easy to route during installation.
• Complete aluminum foil shielding reported by users to keep signals free from interference in installations near electrical noise.
• Plenum CMP rating allows safe use in ceiling plenums and other air-handling spaces where higher flame performance is required.
• Customers note good value and tangle-free dispensing, which makes handling easier on the job.

Cons

• Some users describe the cable as relatively thin, which may concern those preferring bulkier jacketed cable for rugged environments.
• Not intended for high-voltage or non power-limited circuits; limited to Class 3 power-limited applications.

Frequently Asked Questions

Is this cable safe for plenum spaces?
Yes, it carries a CMP/CL3P/FT6 plenum rating suitable for return-air plenums and other air-handling spaces.

Can it be used outdoors?
The jacket is UV resistant for outdoor runs in exposed areas, but it is primarily designed for indoor and plenum installations.

Will the shielding prevent audio interference?
The aluminum foil shield reduces EMI and is effective at maintaining clear audio and communication lines in electrically noisy environments.
