18/4 Fire Security Burglar Station Control Cable CMP - Shielded

In this review of the 18/4 Fire Security Burglar Station Control Cable, the bottom line is simple: this is a practical, installation-friendly cable for installers and facility managers who need reliable, low-voltage wiring for fire alarm, security and communication systems. The reviewer found the cable's pure copper conductors and plenum-rated CMP jacket to be the single biggest reasons to choose it, since they combine dependable conductivity with safety for air-handling spaces. Ease of pulling and the included rip cord make the product a sensible pick for both retrofit and new-construction work.

Key Features

• Applications: Designed for fire alarm, burglar alarm, intercom and access control, it supports a wide range of low-voltage, power-limited systems.
• Pure copper conductors: Solid pure copper construction provides consistent conductivity and reliable signal performance for alarm and communication circuits.
• 300V CL3 power-limited rating: Rated for 300V and classified CL3P, the cable handles typical power-limited loads and system surges safely.
• Plenum-rated CMP jacket: The CMP/CL3P/FPLP flame-retardant jacket offers the higher fire-safety rating required for plenum spaces.
• Installation-friendly design: A round slick jacket, smooth edges and a rip cord simplify pulling through conduit, trays and rough openings.
• Shielded construction: Shielding reduces interference for sensitive communication lines and improves performance in mixed-signal environments.

Who It's For

The cable is aimed at electrical contractors, alarm technicians and building engineers who run wiring for fire security, public address and intercom systems where a plenum rating is required. Its shielding and pure copper conductors make it suitable when signal integrity matters, for example in AC communication or LED cabinet lighting runs tied into control systems.

Customers who only need basic non-plenum residential wiring or very long-distance telecom runs may prefer a different, unshielded or specialty cable better matched to those specific needs. This is not a general-purpose high-voltage power cable; it is intended for power-limited low-voltage circuits.

Pros & Cons

Pros

• Reliable pure copper conductors deliver consistent conductivity and performance.
• Plenum-rated CMP jacket increases safety for air-handling spaces and commercial installs.
• Shielding improves noise rejection for communication and alarm circuits.
• Slick round jacket and rip cord make pulling and termination easier for installers.

Cons

• Designed for power-limited low-voltage use only, not suitable for mains or high-voltage applications.
• The plenum jacket can be stiffer than non-plenum alternatives, which may be slightly harder to route in tight bends.

Specifications

Our Verdict

The 18/4 plenum-rated shielded control cable is a solid choice for professionals who need a dependable, installation-friendly wire for fire alarm, access control and communication circuits. Its pure copper conductors, shielding and CMP jacket deliver safety and signal integrity at a reasonable cost, making it good value for commercial and mixed-use projects where plenum compliance is required.

Frequently Asked Questions

Is this cable suitable for plenum spaces?
Yes. It carries a CMP/CL3P/FPLP plenum-rated jacket suitable for air-handling spaces.

Can this cable be used for mains power?
No. It is a 300V CL3 power-limited cable intended for low-voltage alarm and communication systems, not for mains circuits.

Does the shielding help with interference?
Yes. The shielded construction reduces electromagnetic interference and is helpful for communication and sensitive signal lines.
