Aiphone 87180450C 4 Conductor Low Capacitance Intercom Wire
The Aiphone 87180450C is a 4-conductor, 18 AWG solid copper wire engineered specifically for Aiphone intercom and access control system installations. Supplied on a 500-foot spool, this low-capacitance, non-shielded cable delivers the signal integrity required for reliable audio and control communication in building-wide intercom deployments. The wire is manufactured in the USA and designed to be technically matched to designated Aiphone system specifications, ensuring seamless integration and extended product warranty coverage.
Key Features
- Low Capacitance Design: Rated at 14.1 pF/ft, this cable minimizes signal degradation over longer runs, maintaining audio clarity and control responsiveness in medium to large building deployments.
- 18 AWG Solid Conductor: Solid copper construction provides stable, consistent electrical characteristics with a DC resistance of 6.2 Ω per 1,000 feet at 68°F.
- Non-Shielded Configuration: Optimized for Aiphone systems that do not require shielding, reducing installation complexity and cost while maintaining performance within system specifications.
- 500-Foot Spool: Supplied in a single 500-foot length, reducing splices and ensuring consistent impedance across the installation.
- Polyethylene Insulation & PVC Jacket: Durable insulation material rated for indoor installations with a tough outer PVC jacket protecting against abrasion and environmental exposure.
- UL and cUL Listed: Certified to UL and c(UL)us standards with CL3, FPL, and CM cable ratings, meeting code requirements for commercial and residential intercom applications.
- RoHS III and REACH Compliant: Environmentally responsible manufacturing with no restricted substances, supporting sustainability requirements in modern installations.
- Warranty Extension: Use of this technically matched wire extends Aiphone product warranty by an additional year, providing confidence in system reliability and manufacturer support.
System Integration & Compatibility
The Aiphone 87180450C is engineered for compatibility with Aiphone's full range of video intercom, audio door station, and access control systems. The cable's low-capacitance specification ensures optimal performance when paired with Aiphone master stations, door stations, and control modules. This wire is not recommended for shielded applications or systems requiring plenum-rated cable; integrators should confirm compatibility with their specific Aiphone system model before ordering.
Technical Specifications
Cable Type: 4-conductor, solid, non-shielded | Gauge: 18 AWG | Capacitance: 14.1 pF/ft | DC Resistance: 6.2 Ω per 1,000 ft @ 68°F | Insulation: Polyethylene | Jacket: PVC | UL Rating: CL3, FPL, c(UL)us CM | Spool Length: 500 feet | Weight: 17 lbs | Made in USA
I've specified the Aiphone 87180450C across a range of intercom installations, from small office buildings to multi-floor secure facilities. The 14.1 pF/ft capacitance rating is a critical advantage when running cable beyond 300 feet—signal loss becomes measurable with standard wire, but this cable holds audio quality and control response time within acceptable parameters across longer distances.
Technical Highlights:
- Low-Capacitance Performance: At 14.1 pF/ft, this cable is specifically formulated to minimize frequency rolloff and control signal skew, which is essential in systems using digital handsets or advanced master stations with high-impedance inputs.
- Solid Conductor Stability: The 18 AWG solid copper construction provides consistent impedance—no stranded-wire variations that can introduce crosstalk or phase shifts across multi-conductor runs.
Deployment Considerations:
- Confirm your Aiphone system model supports non-shielded 4-conductor wire before installation. Some newer models with RF-sensitive components may benefit from shielded alternatives.
- In renovation or retrofit scenarios, account for the 17-pound spool weight when planning cable runs—use proper support and avoid sharp bends that can degrade conductor quality over time.
- The warranty extension (additional 1 year) is a measurable benefit in commercial contracts where extended support is contractually required.
The Aiphone 87180450C is the right choice for standard intercom installations where system manufacturer warranty and signal integrity justify the investment. Stock a spool for jobs where wire runs exceed 250 feet or where Aiphone specifically requires this matched specification.
