Aiphone 871804P50C 4-Conductor Plenum-Rated Intercom Cable

The Aiphone 871804P50C is a purpose-built 4-conductor intercom cable engineered to extend the reach and reliability of Aiphone door stations, master stations, and access control systems. Supplied in a 500-foot spool, this cable is rated for plenum environments and manufactured to exacting specifications that ensure compatibility with Aiphone's designated system requirements. Specifying the correct cable is essential for system performance and warranty coverage—the 871804P50C extends product warranty by one additional year when used as the manufacturer recommends.

Key Features

• Plenum-Rated Construction: UL and c(UL)us listed as CL3P, FPLP, and CMP (FT-6), meeting fire code requirements for installation in building air plenums and other restricted environments
• 18 AWG Solid Conductor: 4 conductors in solid copper configuration for reliable signal transmission and durability in fixed installations
• Foamed FEP Insulation: Low-capacitance insulation material rated at 23.6 pF/ft, minimizing crosstalk and signal degradation over long cable runs
• Plenum-Rated PVC Jacket: Non-shielded design with plenum-grade jacket material suitable for direct installation in air return spaces without conduit
• 500-Foot Spool Length: Full 500-foot spool supports large-scale installations and reduces splice points across multiple zones
• RoHS II and REACH Compliant: Meets EU environmental standards and restriction-of-hazardous-substances requirements for global deployment
• DC Resistance: 6.8 ohms per 1,000 feet at 68 degrees Fahrenheit, ensuring voltage stability across extended runs
• Made in USA: Domestic manufacturing supports supply chain reliability and quality consistency

Technical Specifications

This Aiphone 871804P50C cable is engineered for mid-capacitance applications where signal integrity and plenum compliance are mandatory. The 4-conductor, 18 AWG solid-copper design with foamed FEP insulation supports both analog and digital intercom signaling. The jacket material meets plenum safety standards (CMP rating), eliminating the need for conduit in air return plenums, return-air ducts, and other air-handling spaces. Total weight is 17 pounds per spool.

Integration & Compatibility

The 871804P50C is technically matched to Aiphone intercom and access control systems, including JVS and JOS box sets, JV series master stations (JV-1MD, JV-1FD), vandal-resistant door stations (JV-DVF, JV-DV), and audio door stations (AX-DM). Proper cable selection maintains system warranty coverage and ensures performance within manufacturer specifications. Consult Aiphone system documentation to confirm cable requirements for your specific configuration.

From a systems integration standpoint, the Aiphone 871804P50C represents a critical infrastructure decision. Plenum-rated cable is not a convenience—it is a code compliance requirement in many jurisdictions, and using non-plenum cable in air return spaces creates both legal and safety risk. This cable eliminates that concern entirely.

Technical Highlights:

• Plenum Fire Rating: UL/cUL listed CMP rating means this cable can be installed directly in building plenums without conduit, reducing labor and materials cost while ensuring code compliance
• Low Capacitance Design: At 23.6 pF/ft, the 871804P50C minimizes signal degradation, allowing longer cable runs without repeaters or signal conditioning
• Warranty Extension: Using this cable with Aiphone systems extends the product warranty by one year, reflecting manufacturer confidence in the cable quality and system compatibility

Deployment Considerations:

• Verify plenum requirements before installation; if your cable runs avoid plenums, evaluate non-plenum alternatives to optimize budget
• Plan for adequate spool storage and management—500 feet is substantial; consider cable management practices to prevent kinks and deformation
• Confirm conductor count and gauge match your system specification; 4-conductor designs support standard analog and digital intercom signaling, but some expansion modules may require different configurations

The 871804P50C is a straightforward choice for Aiphone system installations where plenum compliance is required. Its low capacitance and solid-conductor design deliver reliable performance across extended runs, and the warranty extension provides tangible recognition of quality. Stock this cable when deploying mid-to-large Aiphone systems in commercial or institutional environments.
