Aiphone TC-40G 40-Call Add-On Selector
Overview
The Aiphone TC-40G is a 40-call add-on selector module designed to expand existing TC-M Series intercom systems. This expansion unit integrates seamlessly with TC-M master stations and other compatible components, enabling facilities to scale their voice communication infrastructure across larger installation footprints without requiring a complete system replacement. The TC-40G (often searched as TC 40G) serves as a modular selector that connects to the core TC-M platform, allowing administrators to add 40 additional call buttons to an existing deployment.
Key Features
- Expands TC-M Series systems with 40 additional call buttons
- Modular add-on design integrates with existing TC-M infrastructure
- Scalable architecture supports multi-station deployments
- Selector-based button interface for efficient station routing
- Compatible with TC-10M and TC-20M master stations as primary control points
- Works with TB-SE handset sub-stations for distributed call handling
- Supports integration with door station adapters (TB-AD10) for access control coordination
- Extends voice communication capability across facilities without system redesign
- Connects via standard 2-conductor shielded wiring (22 AWG recommended)
- Powered by standard 18V DC supply (PS-1820UL or equivalent)
Integration & Compatibility
The TC-40G integrates directly into TC-M Series architectures. Facilities deploying this selector typically pair it with a TC-10M or TC-20M master station as the primary command and control point. The selector module connects via 2-conductor, 22 AWG shielded wire, with wire runs up to 1,000 feet supported using standard cable specifications (part 82220210C or 82220250C). Power distribution utilizes the PS-1820UL 18V DC power supply rated at 2A and UL listed for safety compliance.
When deploying the TC-40G in multi-station environments, integrate it with TB-SE handset sub-stations to distribute call-handling capability throughout the facility. For facilities requiring door station integration, the TB-AD10 door station adapter (supporting up to 10 doors) works in parallel with the TC-40G expansion unit. Call extension speakers (IER-2) can be added to any station to provide area-wide audio announcements when needed.
System Architecture & Scaling
The TC-40G selector module enables horizontal system scaling without architectural redesign. As facility requirements grow, additional TC-40G modules can be cascaded to incrementally expand call-station capacity. This modular approach reduces capital expenditure compared to full system replacement and simplifies field installation since existing cabling and power infrastructure can often be leveraged.
Administrators should plan wire runs during initial deployment to accommodate future TC-40G additions. The 2-conductor shielded specification (22 AWG minimum) ensures signal integrity across extended runs, and proper shield termination at both ends prevents cross-talk and RF interference in multi-module environments.

I've specified the Aiphone TC-40G in several large healthcare and educational facility deployments where existing TC-M systems needed capacity expansion. The selector module approach offers a pragmatic path to scale voice communication infrastructure without equipment consolidation or service interruption during migration.
Technical Highlights:
- Modular Expansion: 40-button selector adds discrete call-routing capacity to TC-M platforms, enabling administrators to grow systems incrementally as occupancy or operational demands increase.
- Power & Connectivity: Operates on standard 18V DC supplied via UL-listed PS-1820UL power supply; all interconnects use industry-standard 2-conductor shielded wire with runs extending to 1,000 feet.
- System Integration: Works alongside TC-10M/TC-20M master stations, TB-SE sub-stations, and TB-AD10 door adapters, allowing architects to compose systems that match facility topology without forcing over-provisioning.
Deployment Considerations:
- Plan wire routing conservatively during initial build to accommodate future TC-40G modules; 22 AWG shielded cable ensures signal integrity across longer runs and multi-module cascades.
- Verify 18V DC supply capacity before adding multiple selectors; larger deployments may require secondary power distribution points to maintain voltage stability across the system.
- Integrate with IER-2 call extension speakers in common areas if area-wide announcements are required; this avoids routing all alerts through individual station handsets.
The TC-40G is a solid choice for integrators working with existing TC-M installations where capacity growth is predictable but phased. The modular design reduces upfront capital burden and allows you to match expansion timing to actual facility demand rather than forecasted peaks.
