Aiphone 82221050C 10-Conductor Shielded Wire
Overview
The Aiphone 82221050C is a professional-grade 10-conductor, 22AWG shielded wire engineered specifically for intercom system installations. Supplied in a 500-foot spool, this multi-conductor cable features an overall shield design to minimize electromagnetic interference and ensure reliable signal transmission across extended runs. Manufactured in the USA and rated for commercial and residential fire-rated environments, the 82221050C meets rigorous electrical and safety standards required by security integrators, telecommunications contractors, and system installers.
Key Features
- 10-Conductor Configuration: Multi-conductor design supports full channel capacity in Aiphone intercom master stations and sub-station networks
- 22 AWG Gauge: Optimized conductor size for voltage drop performance over 500-foot runs while maintaining flexibility for installation in conduit and retrofit applications
- Overall Shield: Multi-conductor shielding reduces crosstalk and EMI interference, critical in facilities with high radio frequency or electrical noise
- UL CL3R / FPLR Rated: Meets UL fire-rating standards (CL3R in dry locations, FPLR in plenum/riser spaces); c(UL)us CMR FT-4 certification ensures compliance with North American electrical codes
- PVC Insulation and Jacket: Chemical and flame-resistant polyvinyl chloride materials rated for indoor building runs; provides durability in standard commercial and residential environments
- RoHS III and REACH Compliant: Lead-free construction and compliance with European chemical safety regulations ensure environmental responsibility and future regulatory alignment
- Made in USA: Domestic manufacturing supports supply chain reliability and quality consistency
- Extended Warranty: Use of technically matched wire extends product warranty by one additional year on compatible Aiphone systems
- 500-Foot Spool: Full-length reel eliminates intermediate splices on large installations; 19 lbs net weight provides manageable handling for two-person installation teams
Integration & Compatibility
The 82221050C is technically matched to Aiphone LEF-series master stations (LEF-10, LEF-10C, LEF-10S, LEF-5, LEF-5C, LEF-3, LEF-3C, LEF-3L) and LE-series sub-stations (LE-A, LE-AN, LE-B, LE-BN), ensuring proper impedance matching, signal integrity, and system performance. System designers and installers should verify conductor count against specific master station channel requirements before ordering. The 10-conductor format supports full-capacity analog intercom networks without the need for supplementary signal or power runs.
Typical Installation Applications
Suitable for new construction rough-in phases, retrofit retrofitting in existing conduit, and large-scale multi-building campus deployments. Fire-rated jacket (FPLR) qualifies this cable for installation in plenum spaces and vertical riser runs where standard communications cable is prohibited by code. Use in dry indoor environments; do not expose to direct outdoor weathering or UV without conduit protection.
I've specified the Aiphone 82221050C on several large intercom refresh projects, and the 10-conductor shielded configuration delivers the cable backbone needed for full-scale analog systems without compromise. The 500-foot spool length eliminates mid-run splices that introduce failure points; on a recent 3-building campus deployment, we ran the entire primary backbone on a single spool.
Technical Highlights:
- Shielding Effectiveness: Overall shield design noticeably reduces buzz and RF noise in electrically noisy environments (near motor control centers, LED lighting systems). The 82221050C consistently outperforms unshielded 10-conductor alternatives in pre-installation site surveys.
- Fire Rating Flexibility: CL3R/FPLR dual certification means one SKU covers both dry wall runs and plenum spaces, simplifying procurement and reducing installation delays from code compliance rejections.
- Warranty Extension: Using manufacturer-matched wire protects warranty coverage—a detail often overlooked in competitive bidding but critical for service response times if ground faults or signal degradation occur post-installation.
Deployment Considerations:
- Verify master station channel count before ordering; LEF-3 systems use 3 channels, while LEF-10 systems require the full 10-conductor capacity. Ordering wrong conductor count forces expensive rework.
- In retrofit runs through existing conduit, account for conductor fill limits per NEC Article 300; 10 conductors at 22AWG occupy approximately 0.0243 cubic inches per conductor, totaling ~0.24 cubic inches per linear foot of cable.
- Allow extra spool length for termination at each master and sub-station (minimum 8 inches per connection); plan 2-3% waste on 500-foot runs for testing, rework, and wall penetrations.
The 82221050C is a straightforward but essential choice for integrators committed to code compliance, noise immunity, and long-term system reliability. Pair it with proper termination blocks and insulation displacement connectors (IDCs) rated for 22AWG multi-conductor termination, and you'll have a backbone that outlasts the equipment it supports.
