Audio cable Belden Security & Sound 22-4c BC, model 5502FE.00152, 4 conductors, 22 AWG, BC construction

Belden Security & Sound 22-4c BC is a four-conductor audio cable with 22 AWG bare copper conductors designed for low-voltage audio and security wiring. The cable is intended for fixed installations in sound systems, intercoms, paging (PA) systems and other signal transmission applications where reliable conductivity and straightforward termination are required. Its compact 4-conductor layout and BC (bare copper) conductor type provide predictable electrical performance for short- to medium-length runs in commercial and residential installations.

Advantages

The cable offers consistent electrical characteristics and low DC resistance due to its 22 AWG bare copper conductors, which helps preserve signal integrity in low-voltage audio and control circuits. Its four-conductor configuration simplifies wiring for multi-channel audio, intercoms or signaling lines while reducing the need for multiple single-conductor runs. The construct is appropriate for terminating with common audio connectors, terminal blocks or screw terminals, enabling straightforward installation and maintenance.

Suitable for

• Low-voltage audio connections (e.g., fixed speakers, preamp/processor links)
• Intercom and door-entry systems
• Paging and public-address (PA) systems
• Signal and control wiring in security installations
• Short- to medium-length runs in commercial and residential buildings

When it may not be suitable

This cable is intended for low-voltage audio and signal applications and is not designed for mains power distribution or high-current circuits. It may not be suitable for long-distance runs where higher-gauge conductors or balanced (shielded/twisted-pair) cable types are required to prevent noise, crosstalk or significant voltage drop. For outdoor or direct-burial installations, a cable with appropriate environmental jacket and ratings should be selected.

Key specifications

• Number of conductors: 4
• Conductor size: 22 AWG
• Conductor material: bare copper (BC)
• Intended use: low-voltage audio, intercom, PA and signal wiring
• Typical termination: connector, terminal block or screw terminal

How to use

Strip the outer jacket and individual conductors to the required lengths, taking care to avoid nicking the bare copper. Route the cable following building codes and installation practices, keeping runs away from large electrical mains wiring to reduce interference. Terminate conductors to the appropriate connectors or terminal points according to the system wiring diagram, and verify continuity and polarity before powering equipment. For multi-conductor connections, label conductors or document color coding to ensure consistent reconnection during maintenance.

What to consider before purchase

• Length required and expected voltage drop for the planned run lengths
• Whether shielding or twisted-pair construction is needed for noise-prone environments
• Installation environment (indoor, outdoor, plenum, or direct burial) and required jacket ratings
• Compatibility with existing connectors and termination hardware

Usage recommendations

Use this 4-conductor, 22 AWG bare copper cable for short- to medium-length low-voltage audio and signaling runs indoors. Keep cable runs separate from high-voltage mains and consider using shielded or higher-gauge cable where electromagnetic interference or long distances could affect audio or control signal quality.
