Security & Sound Cable Belden 4302UE.00100 — 4-conductor audio/security cable

Belden Security & Sound 4302UE.00100 is a 4-conductor audio and security cable designed for low-voltage signal transmission in commercial and residential installations. The cable supports balanced and unbalanced audio lines as well as alarm and monitoring circuits, offering conductor separation and continuous shielding to reduce electromagnetic interference. It is intended for in-wall, conduit, and rack-to-device wiring where reliable signal integrity is required.

Advantages

The cable provides four separately insulated conductors in a compact assembly, enabling multiple audio or security circuits within a single jacket. Continuous shielding improves resistance to external noise and crosstalk, and the construction is optimized to maintain consistent impedance for audio applications. Its robust outer jacket offers mechanical protection during installation and in typical building environments.

Suitable for

• Balanced and unbalanced audio connections between devices and mixers
• Alarm system loops and zone wiring in security installations
• Low-voltage signal runs for monitoring equipment and sensors
• In-wall or conduit runs in commercial and residential AV systems

When it may not be suitable

This cable is not intended for mains power distribution or high-voltage applications; it is designed specifically for low-voltage audio and security signals. For outdoor aerial runs or direct burial installations, a cable with dedicated UV-resistant and water-blocking properties should be selected instead.

Key specifications

• Number of conductors: 4
• Conductor insulation: individually insulated conductors
• Shielding: continuous overall shield to reduce EMI and crosstalk
• Intended use: audio, security/alarm circuits, low-voltage signal transmission
• Typical installation: in-wall, conduit, rack-to-device cabling

How to use

Route the cable according to local building codes, avoiding proximity to mains power lines to minimize interference. Terminate conductors with appropriate connectors or terminal blocks for balanced or unbalanced audio and for alarm panels, following the device wiring diagrams. Maintain shield continuity by grounding the shield at one end where specified by the system design. Use strain relief and proper cable management in racks and conduits to prevent mechanical stress on terminations.

What to consider before purchase

• Verify that a 4-conductor cable meets the number of circuits and gauge requirements for your audio or security system
• Confirm that in-wall and conduit ratings match local electrical and fire codes
• Determine whether additional environmental protections (UV, moisture, direct burial) are required for your installation

Usage recommendations

For best results in audio and security systems, use separate runs for sensitive audio lines where possible, ground the cable shield according to system recommendations, and avoid bundling with mains power cables. Label both ends of each conductor during installation to simplify future maintenance and troubleshooting.
