Cable Belden Security & Sound 2-conductor (model 4200ULW.00305) for audio and security systems

Belden Security & Sound 2-conductor cable (model 4200ULW.00305) is intended for low-voltage audio and security wiring in indoor environments. The cable features two insulated conductors in a compact jacket, providing a straightforward route for transmitting audio signals, alarm circuits and intercom connections. It is suitable where a basic, reliable two-wire connection is required for speakers, sensors and other low-power devices.

Advantages

The cable offers consistent impedance and low electrical loss appropriate for short- to medium-length audio runs and security signal wiring. Its two-conductor design simplifies installation and termination. Constructed by a recognized manufacturer, the product follows industry practices for insulation and jacketing suitable for indoor applications, delivering stable signal transmission for voice, alarm and trigger circuits.

Suitable for

• Fixed indoor speaker wiring and audio patch connections
• Intercom and door-entry systems
• Alarm sensors, reed switches and simple alarm loops
• Low-voltage control and trigger circuits in security systems

Key specifications

• Two insulated conductors for bidirectional low-voltage signal transmission
• Indoor-rated jacket suitable for wall runs and conduit installation
• Designed for audio and security system signal levels (low-voltage)
• Compact round profile for easy routing and termination

How to use

Strip the outer jacket and insulation from the conductors according to the terminal requirements of the equipment. Route the cable along walls or through conduit to avoid sharp bends and mechanical stress. For optimal signal quality, keep runs as short as practicable and separate the cable from high-voltage power lines to minimize interference. Secure the cable with appropriate clamps or ties and terminate using compatible screw or spring terminals on speakers, alarm panels or intercom units.

Usage recommendations

Use this two-conductor cable for indoor, low-voltage audio and security connections where a simple, reliable two-wire solution is sufficient; for longer runs or environments with high electrical noise, consider shielded or multi-conductor alternatives.
