Aiphone 82221550C 15-Conductor Shielded Cable
The Aiphone 82221550C is a multi-conductor, shielded wire designed specifically for Aiphone intercom and access control system installations. This 500-foot spool delivers 15 conductors at 22AWG gauge with an overall electromagnetic shield, ensuring signal integrity in complex wiring runs and noise-prone environments. Manufactured in the USA and engineered to match the exact specifications of designated Aiphone systems, this cable extends product warranty by one additional year when used with compatible equipment.
Key Features
- 15-Conductor Design: Supports multi-channel intercom stations and master units requiring multiple signal paths in a single cable run
- 22AWG Gauge: Optimized wire diameter for balanced signal transmission and voltage drop performance over extended distances
- Overall Shield: Multi-conductor shielding reduces electromagnetic interference (EMI) and crosstalk, critical in commercial installations near electrical panels, HVAC, or telecom infrastructure
- PVC Insulation & Jacket: Chemical-resistant PVC protects conductors and outer jacket against moisture, UV exposure, and mechanical stress during installation and long-term deployment
- UL and c(UL)us Listed: Meets North American fire and safety standards; CL3R and FPLR ratings certify suitability for in-wall and plenum-adjacent runs
- FT-4 Rating: Complies with FT-4 flame-propagation requirements for commercial building code compliance
- RoHS III & REACH Compliant: Meets EU and North American environmental and material restriction standards, ensuring compatibility with regulated procurement environments
- 500-Foot Spool: Bulk length reduces connectors and termination points, lowering installation time and potential failure points
- Made in USA: Domestic manufacturing ensures consistent quality and supports supply chain resilience
- Warranty Extension: Using the 82221550C with compatible Aiphone systems automatically extends the manufacturer warranty by one year
Integration & Compatibility
The 82221550C is engineered as a system-matched cable for Aiphone analog intercom master stations including the LEF-10, LEF-10C, LEF-10S, LEF-5, LEF-5C, LEF-3, LEF-3C, and LEF-3L models, as well as surface-mount and semi-flush sub-stations (LE-A, LE-AN, LE-B, LE-BN series). The 15-conductor configuration accommodates multi-channel installations where master stations control numerous sub-stations or door release mechanisms. When deployed in accordance with Aiphone system design guidelines, the 82221550C maintains signal fidelity across the full audio spectrum and control circuits required for call signaling and audio transmission.
Package Contents
One 500-foot spool of 15-conductor, 22AWG shielded wire. Cable weight is 26 lbs.
I've specified the Aiphone 82221550C on multi-unit intercom deployments where distance and noise immunity are critical. This cable is purpose-built for Aiphone's master-station topology, and the overall shield design consistently outperforms unshielded alternatives in environments with high electromagnetic activity—common in modern commercial buildings with extensive network, power distribution, and HVAC control infrastructure.
Technical Highlights:
- Multi-Conductor Shielding: The overall shield (not individual conductor shielding) reduces EMI across all 15 conductors simultaneously, a practical choice for cost and flexibility in bundled runs
- 22AWG Conductor Gauge: At this gauge, voltage drop over 500 feet remains within acceptable limits for sub-station signaling and audio circuits, avoiding costly intermediate amplification
- UL/c(UL)us and CL3R/FPLR Rating: Permits in-wall installation in commercial occupancies without conduit, reducing labor cost and installation time where local code allows
Deployment Considerations:
- Plan for the full 500-foot spool on single-run jobs; partial spools are not available, so estimate wire runs carefully to avoid waste or shortage
- Terminate with quality connectors matched to Aiphone station inputs; poor termination negates shielding benefits and invites hum and crosstalk
- Route away from high-current power feeders and unshielded control cables where practical; if co-location is unavoidable, maintain minimum 12-inch separation
- For runs exceeding 300 feet in harsh RF environments (near radio transmission, industrial equipment), consider conduit to further attenuate external noise
The 82221550C is a solid foundation cable for intercom infrastructure that demands reliability. Its warranty extension incentive and system-matched engineering make it a low-risk choice for integrators building Aiphone installations that must perform for 5+ years without audio degradation or intermittent control faults.
