Belden 5520UE 22 AWG 2 Solid Conductor Unshielded Sound & Security Cable | CMR Riser Rated

Belden 5520UE is a commercial-grade, 2-conductor unshielded security and audio cable engineered for basic multi-purpose low-voltage installations in commercial and residential settings. Featuring 2 independent 22 AWG conductors, this cable is UL-rated as CMR (Communications Riser), making it safe and compliant for vertical installations between floors, inside riser shafts, or within walls. Utilizing a solid-core layout, it offers enhanced structural integrity, lower DC resistance over long distances, and straightforward termination onto standard panels.

Key Features of Belden 5520UE

• Ultra-Compact 2-Conductor Build: Packages a single circuit path (2 discrete 22 AWG conductors) into an optimized, narrow-profile cable jacket, minimizing footprint in crowded conduits, terminal boxes, and narrow wall cavities.

• CMR Riser Safety Rating: Certified with a UL 1666 Riser rating. The flame-retardant PVC jacket is engineered to prevent the spread of fire vertically from floor to floor, satisfying strict commercial building code requirements.

• Highly Conductive Solid Copper: Manufactured with premium, solid bare copper conductors. Unlike its stranded counterpart (5500UE), this solid configuration delivers maximum signal integrity, lower attenuation over long cable runs, and stable punch-down, crimp, or screw-terminal terminations.

• Premium Polyolefin Insulation: Conductors are wrapped in a high-dielectric polyolefin insulation. This formulation ensures stable electrical performance and prevents physical conductor-to-conductor shorts within the jacket.

• Rip Cord Integration: Includes a built-in nylon rip cord beneath the jacket, allowing installers to easily score and strip back long sections of the outer sheath without risking damage to the inner conductor insulation.

Common Applications

• Commercial Security Systems: Interconnecting single-zone door contacts, window sensors, glass-break detectors, motion sensors, and panic buttons to control panels.

• Intercom & PA Systems: Connecting individual localized intercom stations, public address horn networks, and master control voice lines.

• Sound & Audio Distribution: Wiring low-voltage background music systems, residential stereo zones, and commercial 70V/100V speaker lines where solid-core cabling is preferred.

• Background Control & Signaling: Distributing simple low-voltage digital signals, single-stage relay controls, HVAC remote temperature sensors, thermostat linkages, and LED status indicators.

Technical Note: Because Belden 5520UE is an unshielded cable with solid conductors, it is optimized for fixed, permanent installations within walls or conduits. It should not be utilized in applications requiring continuous flexing, such as inside robotic tracks or on moving machinery. Additionally, to avoid signal degradation, noise coupling, or data corruption, do not route this low-voltage cable parallel to high-voltage AC power lines (120V/240V or higher) within the same wall cavity or conduit unless separated by an approved physical barrier or a minimum distance of 50 mm (2 inches). If your layout requires installation through drop ceilings utilized for environmental air exchange, the plenum-rated equivalent (Belden 6520UE) must be used instead.
