Aiphone 82222050C Multi-Conductor Shielded Wire
The Aiphone 82222050C is a 20-conductor, 22 AWG shielded wire designed to meet the exact specifications of Aiphone intercom and access control systems. This 500-foot spool provides the infrastructure backbone for multi-channel master stations and distributed sub-stations in residential, commercial, and institutional installations. Built with overall shield protection and UL/cULus certification, the 82222050C ensures reliable signal transmission while meeting strict fire and safety ratings.
Key Features
- Multi-conductor configuration: 20 conductor, 22 AWG design extends system capability to larger channel configurations
- Overall shield: Reduces electromagnetic interference and crosstalk in mixed-signal environments
- Insulation material: PVC insulation and jacket for durability and flexibility in conduit or in-wall installations
- UL and c(UL)us listing: Certified to CL3R, FPLR, and CMR FT-4 ratings for commercial and residential fire-rated applications
- RoHS III and REACH compliance: Meets environmental and material restriction standards for global distribution
- Made in USA: Manufactured domestically to ensure consistent quality control and supply chain reliability
- Extended warranty: Technically matched wire extends product warranty by one additional year when used with designated Aiphone systems
- 500-foot spool: Bulk length reduces connectors and splice points, improving system integrity across large or multi-floor deployments
- Compatible with LEF series: Supports LEF-3, LEF-5, LEF-10, and all analog master station configurations requiring distributed sub-station wiring
Integration & Compatibility
The 82222050C is engineered specifically for Aiphone intercom systems and integrates seamlessly with the full range of LEF analog master stations (LEF-3, LEF-3C, LEF-3L, LEF-5, LEF-5C, LEF-10, LEF-10C, LEF-10S) and LE-series sub-stations (LE-A, LE-AN, LE-B, LE-BN). The 20-conductor design accommodates high-density multi-channel configurations typical in large residential communities, office parks, hospitals, and educational facilities. The shielded construction minimizes signal degradation in electrically noisy environments where proximity to power lines, HVAC systems, or security camera wiring is unavoidable.
Technical Specifications
Cable Rating (UL): CL3R, FPLR, c(UL)us CMR FT-4 — ensures compliance with commercial building codes and fire alarm installation standards. Insulation & Jacket: Both PVC for consistent performance across temperature ranges and installation methods. Weight: 37 lbs per 500-foot spool, manageable for single-technician deployment on ladders or wall-mounted reels. Conductor Configuration: 20 conductors at 22 AWG provides balanced impedance for control signaling and audio transmission without excessive voltage drop over standard run lengths.
The 500-foot length is ideal for single-building deployments or primary distribution runs in larger campuses. Pair with shorter gauge runs or additional spools for multi-building or high-rise applications requiring multiple drop points.
I've specified the Aiphone 82222050C wire in multi-unit residential and commercial intercom projects where channel density and cable runs exceed typical 2-conductor or 4-conductor offerings. The 20-conductor configuration eliminates the need for multiple smaller cables, reducing installation time and improving system scalability.
Technical Highlights:
- Shielding & EMI Rejection: The overall shield effectively suppresses radiated interference from building electrical systems, elevator motors, and security camera power supplies—critical in environments where cable routing cannot avoid these sources.
- Fire Rating & Code Compliance: CL3R and FPLR ratings satisfy National Electrical Code (NEC) Article 725 requirements for remote-control, signaling, and power-limited circuits in commercial and residential occupancies without requiring conduit in some jurisdictions.
Deployment Considerations:
- Verify local fire code for in-wall vs. conduit routing; CL3R/FPLR status may allow plenum or general-use pathways depending on AHJ interpretation.
- Plan conductor assignment during system design—document which conductors power master stations, audio channels, and remote release circuits to simplify troubleshooting.
- Use appropriate termination panels or punch-down blocks at master station and sub-station endpoints; loose or corroded connections can introduce intermittent failures across multiple channels.
For integrators deploying large intercom systems or upgrading older analog installations, the 82222050C spool length and multi-conductor count justify bulk purchase and storage. Pair with quality termination hardware and a documented wiring schedule to ensure long-term operational reliability.
