Aiphone 86220810C 4-Pair Shielded Twisted Pair Wire 1000'

Aiphone 86220810C 4-Pair Shielded Twisted Pair Wire

The Aiphone 86220810C is a professional-grade communication cable designed for intercom system installations where signal integrity and impedance matching are critical. This 1000-foot spool of 4-pair, 22 AWG shielded wire delivers low-capacitance performance specifically engineered to match Aiphone NHX Series system requirements. The cable's foamed polyethylene insulation and overall shielding minimize crosstalk and environmental interference, making it suitable for both new installations and system expansions requiring extended cable runs.

Key Features

• Low Capacitance Design: Measures 12.1 pF/ft to preserve signal fidelity across extended runs without requiring signal conditioning equipment
• 22 AWG Conductors: Optimized for voice-frequency communication; 16.1Ω per 1000' DC resistance @ 68°F ensures predictable electrical performance
• Overall Shielding: Protects against electromagnetic interference and RF ingress in mixed-use facilities
• Color-Coded Pairs: Factory color-coded to match NHX Series specifications, eliminating field termination errors and reducing installation time
• Foamed Polyethylene Insulation: Provides mechanical protection and consistent dielectric properties over temperature extremes
• PVC Jacket: Durable outer layer rated for in-wall and plenum-adjacent runs
• UL and c(UL)us Listed: Certified for CL3, CM, and FPL cable ratings, meeting fire and safety codes for commercial intercom deployments
• RoHS III and REACH Compliant: Meets environmental and hazardous substance regulations for EU and North American markets
• Extended Warranty: One additional year of warranty coverage when used with designated Aiphone systems
• Domestic Manufacturing: Made in USA for consistent quality control and supply chain reliability
• 1000-Foot Spool: Minimizes connector splices and labor costs on single-floor or multi-story installations

Integration & Compatibility

The 86220810C is specifically matched to Aiphone NHX Series master stations, audio substations, and control units. The low-capacitance specification ensures proper audio frequency response and eliminates the need for line drivers or repeaters on runs up to 1000 feet. Color-coded pair identification aligns with Aiphone's standard wiring conventions, allowing integration teams to work from single-pair schematics without cross-reference tables. The cable's electrical characteristics—particularly the 12.1 pF/ft capacitance and 16.1Ω resistance—have been validated for Aiphone's impedance-matched handset, speaker, and signaling circuits.

When deployed in facilities with existing copper infrastructure, the 86220810C can replace or supplement legacy twisted-pair runs without requiring impedance-matching transformers or active conditioning, provided total system cable length remains within Aiphone's documented limits.

I've specified the Aiphone 86220810C on healthcare, hospitality, and multi-tenant residential projects where reliable intercom coverage across dispersed call stations is non-negotiable. The low-capacitance design is the differentiator here—it eliminates the signal degradation you'd encounter with generic 22 AWG twisted pair, particularly on runs exceeding 500 feet. The color-coded pairs save installation hours because installers don't need to trace and verify continuity manually.

Technical Highlights:

• Capacitance Control: At 12.1 pF/ft, the foamed polyethylene core keeps propagation delay and signal loss minimal, critical for maintaining audio clarity on extended runs without active boosters
• Resistance Specification: 16.1Ω per 1000' ensures predictable voltage drop and loop resistance for Aiphone's signaling circuits, which rely on precise impedance for call-button reliability

Deployment Considerations:

• Verify your total system cable length against Aiphone's documentation before ordering; while 1000 feet is substantial, multiple long runs may exceed the NHX Series' designed electrical limits
• Use the color-coded pairs as-delivered—don't daisy-chain or split pairs across sub-systems, as this violates the impedance-matching that makes the low-capacitance spec valuable
• Terminate into Aiphone-approved jack blocks or terminal strips; generic RJ11 adapters may introduce impedance discontinuities that degrade audio quality

For integrators deploying multi-floor intercom systems or campus-wide nurse call networks, the 86220810C represents the standard wire choice—it's cost-effective, thoroughly validated, and eliminates guesswork around signal integrity. The domestic manufacturing and extended warranty also provide confidence in supply continuity and support.
