Aiphone AT-406 Handset-to-Handset Intercom System
Overview
The Aiphone AT-406 is a straightforward handset-based intercom solution designed for direct two-way voice communication between a primary station and up to three sub-stations. This system delivers effortless connectivity for multi-location facilities that require simple, reliable audio communication without complex installation or programming. The AT-406 configuration includes one AT-206 white audio master station and one AT-306 sub-station handset, enabling immediate deployment for indoor communication applications.
Key Features
- Direct Two-Way Voice Communication: Full-duplex handset communication allows simultaneous talk and listen between primary and sub-station locations
- Primary Station Broadcast Capability: The primary station calls to all connected sub-stations; sub-stations dial directly to the primary station
- Multi-Station Configuration: Supports 1 primary station with up to 3 sub-stations for flexible facility layouts
- PoE+ Powered (802.3at): Operates over Power over Ethernet Plus, eliminating the need for dedicated AC power supplies at individual stations
- Wall and Ceiling Mount Options: Flexible mounting accommodates various installation environments and facility layouts
- Minimal Wiring Requirements: Uses 2-conductor, overall shielded wire (Aiphone #822202) for master-to-sub station connections, reducing infrastructure complexity
- Proven Reliability: Built on Aiphone's 75 years of intercom technology expertise
- White Finish: Clean aesthetic suitable for professional and commercial environments
Integration & Compatibility
The AT-406 operates as a standalone system and integrates standard Aiphone wiring and accessory components. The master station (AT-206) and sub-station handset (AT-306) pair directly with 2-conductor shielded communication wire to form a point-to-point audio network. For installations requiring desk mounting, the optional adjustable desk stand (MCW-S/B) provides flexible positioning. Power supply requirements are met via PoE+ at the network switch or injector, eliminating local power distribution to handsets.
Package Contents
The AT-406 set includes one AT-206 white audio master station and one AT-306 white sub-station handset, providing the core components for immediate two-location communication deployment.
The Aiphone AT-406 represents a no-frills approach to intercom deployment—ideal for facility managers who need reliable audio communication without the overhead of IP-based systems or complex wiring schemes. During architecture reviews, this system stands out for integrating seamlessly into existing PoE infrastructure, reducing both capital expense and installation time.
Technical Highlights:
- Full-Duplex Handset Communication: Simultaneous two-way audio ensures natural conversation flow without push-to-talk latency
- PoE+ Integration: Standard 802.3at power delivery over standard Ethernet eliminates dedicated power infrastructure for each station
- Scalable to 4-Station Networks: Primary broadcast to three sub-stations covers most multi-room facility requirements without additional gateways
Deployment Considerations:
- Wire runs between master and sub-stations must use Aiphone-specified 2-conductor shielded cable to maintain audio quality and comply with voltage drop specifications
- Verify PoE+ availability at your network switch or deploy a PoE+ injector where upstream infrastructure is limited to standard PoE
- Plan cable routing during initial facility survey—runs longer than 300 feet may require signal conditioning or intermediate amplification
For facilities seeking lean, dependable intercom without VoIP complexity, the AT-406 delivers. I recommend this system for secondary communication channels, facility-wide paging supplements, or environments where simplicity and uptime matter more than feature density.
