Aiphone CCS-1A ChimeCom2 Intercom Door Station Master Set
The Aiphone CCS-1A is a single-unit intercom system designed for straightforward door answering in residential and light commercial applications. This classic ChimeCom2 series set includes one door station and one master answering station, delivering 75 years of Aiphone intercom technology in a simplified, wall-mounted configuration. The CCS-1A operates on standard 2-conductor shielded wire, making it compatible with existing doorbell wiring infrastructure for rapid deployment.
Overview
The CCS-1A provides basic audio intercom communication between a visitor at the door station and an answering station mounted indoors. When a visitor presses the door station call button, a pleasant chime alert notifies the occupant of the call. The system uses simple two-way audio to facilitate conversation without requiring video or advanced network integration. Installation leverages existing doorbell wire runs, reducing labor and material costs in retrofit applications.
Key Features
- Complete Master Set: Includes 1 door station and 1 master (answering) station for immediate deployment
- Audio Intercom: Two-way audio communication between door and master stations
- Pleasant Chime Alert: Audible notification when visitor presses door button
- Wall-Mount Design: Both door and master stations mount directly to walls for clean, integrated installation
- Existing Wire Compatible: Works with standard 2-conductor, overall-shielded wiring (Aiphone #822202 22AWG or #821802 18AWG recommended)
- Minimal Setup: Installation on existing doorbell infrastructure eliminates expensive rewiring in retrofit scenarios
Wiring & Installation Requirements
The CCS-1A requires 2-conductor, overall-shielded wire for connection between door and master stations. Aiphone recommends using their certified wire products: model #822202 (22 AWG) or model #821802 (18 AWG) to ensure proper signal integrity and compliance with system specifications. The shielded construction minimizes noise and interference in residential and light-duty commercial environments. Standard AC 12V transformer (such as the Aiphone PT-1210NA) powers the system, with transformers available in multiple sizes depending on wire run length and total load.
Integration & Compatibility
The CCS-1A is a standalone audio intercom and does not integrate with IP-based video management systems, smart home platforms, or network protocols. It functions as a dedicated audio communication device, ideal for applications where simple door-to-room conversation is the primary requirement. No network configuration, software setup, or remote access is required.
Package Contents
The CCS-1A master set includes one door station, one master (answering) station, and necessary mounting hardware. Wire and transformer are sold separately to allow flexibility in system design and wire gauge selection based on installation distance and existing infrastructure.
The Aiphone CCS-1A represents a pragmatic choice for single-door access intercom deployments where video is not required. After evaluating this system during retrofit planning phases, I find its strength lies in the ability to reuse existing doorbell wiring—a significant cost advantage over full video intercom replacements. The CCS-1A simplifies the decision tree: if your primary need is door notification and two-way voice communication, this system delivers without the complexity and cost of network-based alternatives.
Technical Highlights:
- Audio Intercom Only: Two-way voice communication; no video or advanced analytics
- Wiring Efficiency: Operates on 2-conductor shielded wire compatible with legacy doorbell installations; reduces retrofit labor and material cost
- Audible Alert: Integrated chime provides immediate notification without reliance on electronic signaling or app notifications
Deployment Considerations:
- Confirm existing wire gauge and shielding quality; damaged or corroded wiring should be replaced before system installation to ensure reliable audio quality
- Verify AC transformer capacity and total wire run distance; longer runs or multiple stations may require larger gauge wire (18 AWG recommended over 22 AWG for runs exceeding 100 feet)
- This system is not suitable for applications requiring visitor identification, recorded communication, or integration with smart home or security management software
- Position the master station in a high-traffic area to ensure occupants hear the chime alert reliably
The CCS-1A excels in renovation and retrofit scenarios where budget constraints and existing wiring infrastructure guide the system selection. For facilities requiring only basic door-to-room audio communication, this intercom delivers straightforward functionality backed by Aiphone's long-established intercom expertise. Pair it with the correct wire gauge and transformer size for your specific installation distance, and you'll have a reliable, cost-effective access communication solution.
