Aiphone 85220710C 7-Conductor Low Capacitance Wire
The Aiphone 85220710C is a 1,000-foot spool of 7-conductor, 22 AWG non-shielded wire engineered specifically for Aiphone intercom and access control systems. This wire is color-coded to match the MC Series product line and is technically matched to designated system specifications. Built to UL and c(UL)us standards with RoHS III and REACH compliance, the 85220710C delivers the low-capacitance signal integrity required for reliable intercom, paging, and control signal distribution across multi-zone installations.
Key Features
- Low Capacitance Design: 16.5 pF/ft capacitance rating minimizes signal degradation and crosstalk over extended cable runs
- Non-Shielded Construction: Foamed polyethylene insulation with PVC jacket reduces cost while maintaining signal performance for indoor control and intercom applications
- Color-Coded Conductors: Matches MC Series intercom handset and system wiring conventions for rapid field installation and reduced termination errors
- 22 AWG Gauge: 17.5Ω per 1,000 feet DC resistance; optimized for 24VDC power distribution and low-voltage control signals
- UL and c(UL)us Listed: Cable Rating CL3, FPL, and CM classification ensures code compliance for in-wall and plenum installations where permitted
- RoHS III and REACH Compliant: Lead-free and environmentally compliant manufacturing meets international material restriction standards
- 1,000-Foot Spool: Full-spool purchase eliminates connector waste and reduces per-foot cost for large multi-zone deployments
- Made in USA: Domestic manufacturing supports supply chain reliability and stock availability
- Warranty Extension: Use of this technically matched wire extends product warranty by one additional year on compatible Aiphone systems
Technical Specifications
The 85220710C delivers precise electrical characteristics engineered for Aiphone system performance. With a capacitance rating of 16.5 pF/ft, the wire maintains signal fidelity over the full 1,000-foot length, critical for multi-line paging amplifiers and handset installations. DC resistance of 17.5Ω per 1,000 feet at 68°F ensures voltage stability when powering remote speakers, amplifiers, and control devices from centralized 24VDC supplies. Foamed polyethylene insulation provides superior capacitance control compared to solid insulation while the PVC jacket offers mechanical protection and flame rating compliance. The wire is listed under UL and c(UL)us standards with CL3 (Class 3 limited power) and FPL (Fire-resistant Power Limited) ratings, meeting National Electrical Code requirements for low-voltage wiring in commercial and institutional facilities.
Integration and Compatibility
The Aiphone 85220710C is engineered for use with Aiphone MC Series handsets, paging amplifiers (MD120M, MD60M, MD35M models), and MarketCom access control systems. The seven conductors support multi-line telephone wiring, paging control, door access relay circuits, and auxiliary signaling on a single cable run, reducing labor and conduit costs. Color coding aligns with industry-standard telephone wiring conventions, enabling integration with standard termination blocks and keystone connectors. Compatibility with UL-listed Aiphone power supplies (including the PS-2420UL 24V, 2A model) is verified for proper voltage and current delivery to remote terminals and speakers.

As a systems engineer who regularly specifies cabling for multi-line intercom and access control installations, I've found the Aiphone 85220710C to be a reliable choice for facilities deploying Aiphone's MC Series platforms. The 16.5 pF/ft capacitance specification is a meaningful engineering detail—it directly impacts signal quality on long runs and multi-zone configurations where capacitive loading can degrade audio clarity or introduce control signal timing errors.
Technical Highlights:
- Low Capacitance Performance: The 85220710C's 16.5 pF/ft rating keeps signal losses minimal across 1,000-foot spool lengths, reducing the need for intermediate amplification or line driver circuits in typical intercom topologies.
- Seven-Conductor Consolidation: Running one 7-conductor cable instead of three separate 2-conductor or 3-conductor runs cuts labor, conduit fill, and termination points—a practical efficiency gain in retrofit projects.
- UL/c(UL)us and Code Compliance: CL3 and FPL ratings satisfy most commercial and institutional wiring codes without requiring plenum cable upgrades unless local fire-rating requirements mandate it.
Deployment Considerations:
- Verify local electrical code for cable classification in your jurisdiction; some jurisdictions require plenum-rated cable in air-handling spaces regardless of UL listing.
- The non-shielded design works well in office and light-industrial environments but should not be installed in high-EMI areas (near large motors, VFDs, or RF equipment) without conduit shielding.
- For outdoor or direct-burial applications, specify the Aiphone 851602DBW10C shielded, water-blocked alternative instead; the 85220710C is designed for indoor control environments only.
- Confirm conductor count aligns with your system configuration before ordering; this 7-conductor version is optimized for multi-line MC Series handsets and paging amplifiers.
The warranty extension benefit—an additional year of coverage when using technically matched Aiphone wire—reflects the manufacturer's confidence in the product and underscores the importance of cable specification consistency in intercom system reliability. For integrators deploying Aiphone infrastructure at scale, bulk-spool ordering of the 85220710C reduces inventory complexity and ensures all runs meet identical electrical specifications.
