SYSTON 18/4 Fire Security Burglar Station Cable - Plenum-Rated Control

In this review the SYSTON 18/4 fire security burglar station cable is evaluated for installers and facilities managers who need a reliable, plenum-rated control wire for low-voltage systems. The bottom line: this cable stands out for its pure copper conductors and CMP plenum rating, making it a sensible choice when running fire alarm, security, or communication lines through ceiling plenums where flame performance and safety are essential.

Key Features

• Multiple application support: Suitable for fire alarm, burglar alarm, public address, intercoms, telephone stations and other power-limited low-voltage circuits, providing flexibility on mixed projects.
• Pure copper conductors: Stranded bare copper conductors deliver reliable conductivity and flexibility, which helps maintain signal integrity and ease of routing in conduits and raceways.
• CMP plenum-rated construction: The CMP/CL3P/FT6 flame rating permits installation in air handling plenums for projects that require the highest flame retardant performance.
• Standard compliance: Meets NEC 725 and 800 and UL standards including UL 13 and UL 444, with UL and/or ETL listing plus RoHS compliance for regulatory peace of mind.
• 300V, CL3 rating: A 300V insulation rating and CL3 classification make the cable appropriate for Class 3 power-limited uses like thermostats, audio and access control circuits.

Who It's For

This cable is aimed at electrical contractors, low-voltage installers, building maintenance teams and systems integrators who must run control and communication conductors through plenum spaces and need the highest flame performance. It is especially appropriate for commercial and institutional buildings where codes require CMP-rated cable in return-air plenums.

Those working on simple non-plenum residential projects or seeking shielded cable for sensitive signal runs should consider other options; this is an unshielded control cable intended for general low-voltage circuits rather than specialty shielded audio or data runs.

Pros & Cons

Pros

• High flame retardant CMP rating allows safe use in building plenums and ceilings.
• Stranded bare copper conductors provide good conductivity and flexible handling for installation.
• Broad compatibility with fire alarm, security, intercom and other low-voltage systems reduces need for multiple cable types.
• Meets multiple NEC and UL standards, offering regulatory confidence.

Cons

• Unshielded construction means it may not be ideal where electromagnetic interference immunity is required.
• Some users find the conductor thickness thinner than expected for certain heavy-duty runs.

Our Verdict

The SYSTON 18/4 plenum-rated control cable is a practical, cost-effective choice for professionals who need reliable fire alarm and security wiring that can be run in ceiling plenums. Its stranded copper conductors and comprehensive safety ratings provide dependable performance, though installers requiring shielding or heavier gauge conductors should select alternate cables. Overall it delivers strong value where plenum use and compliance are priorities.

Frequently Asked Questions

Is this cable suitable for use in ceiling plenums?
Yes. The cable carries a CMP plenum rating (CL3P/FT6) designed for use in air handling plenums and spaces.

Can this cable be used for security and fire alarm panels?
Yes. It is intended for fire alarm, security burglar stations and other power-limited low-voltage circuits and meets relevant NEC and UL standards.

Does it include shielding for interference protection?
No. This product is unshielded; for runs that require EMI protection a shielded control cable should be chosen.
