Aiphone 82220350C 3-Conductor Shielded Wire
The Aiphone 82220350C is a multi-conductor shielded wire engineered to extend intercom and communication system installations across longer distances while maintaining signal integrity. This 500-foot spool delivers the specifications required for Aiphone master stations, sub-stations, and door station deployments in commercial and institutional environments.
Overview
The 82220350C provides three conductors with 22 AWG gauge and an overall shield designed to reduce electromagnetic interference and cross-talk in multi-device intercom networks. The wire is manufactured in the USA and complies with stringent safety and environmental standards, including UL and c(UL)us listings, RoHS III, and REACH compliance. The overall shield configuration protects signal transmission in areas with moderate RF interference, making this wire suitable for retrofit and new installations in schools, hospitals, corporate offices, and multi-unit residential buildings.
Key Features
- Multi-conductor design: 3 conductors with 22 AWG solid copper for reliable current and signal delivery
- Overall shield: Reduces EMI and provides technical matching to Aiphone system specifications
- Cable rating: UL CL3R, FPLR, c(UL)us CMR FT-4 for use in plenum and non-plenum applications
- Insulation material: PVC insulation and PVC jacket for durability and moisture resistance
- 500-foot spool: Continuous length reduces splice points and installation labor
- UL and c(UL)us listed: Meets North American safety standards for fire rating and electrical performance
- RoHS III and REACH compliant: Environmentally responsible material composition
- Extended warranty: Use of technically matched wire extends system warranty by one additional year
- Made in USA: Domestic manufacturing with quality control traceability
- Compatibility: Engineered for Aiphone NIM-20B and NIM-40B master stations, NI-BA sub-stations, and NI-JA audio door stations
Integration & Compatibility
The Aiphone 82220350C wire is technically matched to Aiphone intercom system specifications, ensuring optimal performance when paired with Aiphone master stations (NIM-20B 20-call or NIM-40B 40-call models), surface-mount sub-stations (NI-BA), and audio door stations (NI-JA). The 3-conductor, 22 AWG configuration supports power delivery from the IS-PU-UL 48V DC power supply and signal transmission across distributed indoor networks. The overall shield provides electromagnetic compatibility in installations where cable runs pass near electrical panels, fluorescent fixtures, or wireless equipment.
Installation Considerations
The 500-foot spool is designed for bulk installations or extended runs in larger facilities. Wire diameter and flexibility allow installation through conduit, surface-mount channels, and existing cable pathways. The PVC jacket resists UV degradation in indoor applications and moderate environmental exposure. Termination to Aiphone master station terminals, sub-station blocks, and door station connectors follows standard low-voltage wire practices. The model 82220350C complies with fire codes for indoor plenum-rated applications (CL3R, FPLR rating), making it suitable for installation in air handling spaces where CL2 or unrated cables are not permitted.
The Aiphone 82220350C addresses a critical requirement in intercom system deployment: reliable, code-compliant connectivity over distance. In my experience evaluating multi-building and multi-floor installations, using the manufacturer's specification-matched wire is often overlooked cost optimization. The 82220350C eliminates guesswork around gauge, shielding, and fire rating.
Technical Highlights:
- Overall shield effectiveness: Reduces EMI ingress in facilities with dense electrical or RF activity, particularly important in healthcare and institutional settings where audio clarity directly impacts safety and security operations
- Fire rating compliance: UL CL3R and FPLR certification eliminates re-work and inspection delays in plenum-rated pathways; c(UL)us CMR FT-4 ensures code acceptance across jurisdictions
Deployment Considerations:
- Warranty extension: Using specification-matched wire (82220350C) versus generic 3-conductor wire adds one year to system warranty—factor this into lifecycle cost comparisons
- Spool management: Plan termination locations before installing the full 500 feet; the continuous length minimizes splice count but requires advance routing design
For integrators and facility managers standardizing on Aiphone intercom infrastructure, stocking the 82220350C reduces lead time, simplifies procurement documentation, and ensures warranty compliance across multiple site deployments.
