Aiphone 82180310C 3-Conductor Shielded Wire
Overview
The Aiphone 82180310C is a 1000-foot spool of 3-conductor, 18AWG shielded wire engineered as an infrastructure component for Aiphone intercom and access control systems. This wire is manufactured in the USA and designed to meet the technical specifications required by designated Aiphone system architectures. The 82180310C integrates an overall shield to minimize electromagnetic interference and ensure reliable signal transmission across multi-conductor runs in residential, commercial, and institutional installations.
Key Features
- Multi-conductor with overall shield: 3-conductor configuration with comprehensive shielding reduces noise and cross-talk, critical for voice clarity and control signal integrity in intercom deployments
- 18AWG conductor gauge: Appropriate for low-voltage, low-current intercom circuits; balances signal integrity with installation flexibility
- 1000-foot spool: Sufficient length for single-run installations or distributed subsystem wiring without mid-run splices
- PVC insulation and jacket: Chemical-resistant, flame-rated materials suitable for in-wall, ceiling, and conduit installations
- UL and c(UL)us listed: Meets North American safety standards; rated CL3R, FPLR, and c(UL)us CMR FT-4 for plenum and riser applications
- RoHS III and REACH compliant: Environmentally responsible materials; meets EU hazardous substance restrictions
- Warranty extension: Using manufacturer-matched wire extends product warranty by one additional year, demonstrating Aiphone's confidence in system longevity
Technical Specifications
Cable Rating (UL): CL3R, FPLR, c(UL)us CMR FT-4 — ensures compliance for concealed, plenum, and riser installations without conduit.
Insulation Material: PVC — provides mechanical protection and flame resistance in enclosed spaces.
Jacket Material: PVC — durable outer layer resistant to moisture and minor abrasion during installation.
Weight: 28 lbs per 1000-foot spool — manageable for single-person deployment on wall reels or pull-boxes.
Made in the USA: Domestic manufacturing ensures supply chain reliability and consistency with Aiphone engineering standards.
Integration & Compatibility
The Aiphone 82180310C is technically matched to Aiphone intercom master stations (NIM-20B, NIM-40B), sub-stations (NI-BA), audio door stations (NI-JA), and peripheral devices (call lights, reset buttons, corridor lights). As a manufacturer-certified component, using this wire preserves system integration integrity and maintains warranty coverage. Installers deploying multi-building or campus-scale systems often combine multiple spools for extended runs or redundant pathways.
From a systems engineering perspective, specifying the Aiphone 82180310C during project planning simplifies field deployment and reduces troubleshooting overhead. The 18AWG shielded format is standard for low-voltage intercom circuits; the overall shield is essential in electrically noisy environments, such as facilities with adjacent motor control wiring or VFD installations. The 1000-foot spool length matches typical single-building vertical runs without mid-run termination complexity.
Technical Highlights:
- Shielding design: Overall conductor shield minimizes EMI ingress, maintaining audio fidelity and control signal reliability in mixed-use facilities
- UL/c(UL)us dual listing: CL3R and CMR ratings permit in-wall and plenum installation without conduit, reducing labor and material costs
- Warranty linkage: Use of the 82180310C extends the parent Aiphone system warranty by one year—a direct incentive to specify matched infrastructure
Deployment Considerations:
- Verify conduit fill ratios if combining multiple runs; 28-pound spool weight is practical for two-person pulls through overhead runs
- In retrofit installations, pre-stage spool on a motorized unreeler to reduce installation time and wire fatigue
- Confirm local fire code acceptance of CL3R/FPL ratings for your building class; most jurisdictions recognize these certifications for intercom cabling
For single-building intercom systems, the 1000-foot spool typically satisfies master-to-subsystem pathways. Order a second spool for campuses with separate buildings or for contingency stock in service-heavy environments. The RoHS III and REACH compliance also simplifies compliance documentation for regulated facilities.
