Aiphone AX-AN Surface Mount Indoor Sub Station with Privacy
Overview
The Aiphone AX-AN is a surface-mounted indoor sub station designed for hands-free intercom communication within the AX Series ecosystem. Built with privacy functionality, the AX-AN prevents unwanted monitoring from the master station while maintaining full two-way communication capability. This sub station serves as a critical endpoint in audio intercom systems deployed across multi-unit residential, commercial, and institutional environments where distributed communication points are required.
Key Features
- Hands-Free Communication: Two-way audio operation activated when the master station initiates contact, eliminating the need for push-to-talk operation at the sub station
- Privacy Feature: Blocks unwanted monitoring from the master station, allowing the sub station to receive calls without master station personnel listening to ambient audio when not actively communicating
- Surface Mount Installation: Direct wall mounting or 1-gang box integration for flexible deployment in lobbies, corridors, common areas, and interior spaces
- Durable ABS Plastic Construction: Impact-resistant polymer housing rated for indoor environments with protection against physical stress common in high-traffic areas
- Cat-5e or 2-Conductor Wiring: Standard low-voltage cabling compatible with existing building infrastructure; supports extended runs up to 980 feet for system scalability
- Compact Form Factor: Unobtrusive profile designed to integrate seamlessly into interior wall spaces without architectural compromise
Integration & Compatibility
The AX-AN integrates with Aiphone AX Series master stations including the AX-8M (8-position audio master), AX-8MV (8-position audio/video master), and AX-8MV-W (white variant). System expansion accommodates up to 8 master stations and 8 sub stations per configuration, with the AX-16SW selector card enabling 16-door or 16-sub-station expansion on larger multi-building deployments. The 980-foot transmission distance over Cat-5e cabling allows placement of sub stations throughout buildings without repeaters or signal conditioning in typical installations.
Technical Specifications
Communication operates in hands-free, duplex mode. The mounting method is surface mount directly to drywall or standard 1-gang electrical boxes. Material construction utilizes impact-resistant ABS plastic. Wiring compatibility includes Cat-5e (preferred) or 2-conductor copper wire per building code standards. System transmission distance reaches 980 feet under standard Cat-5e installation. The AX-AN (often searched as AX AN) operates on low-voltage power supplied by the connected master station unit, with no separate power supply required at the sub station location.
Deployment Considerations
The AX-AN is engineered for indoor installation only and requires protection from moisture, direct sunlight, and temperature extremes. Surface mounting on interior walls allows rapid installation without structural modifications. Privacy functionality is critical in multi-tenant and institutional settings where residents or occupants require call reception without ambient audio exposure during standby periods. The combination of hands-free operation and privacy blocking makes the AX-AN particularly suitable for common areas, management offices, and service corridors where communication efficiency and discretion are both required.
In planning intercom deployments across multi-unit buildings, the AX-AN delivers practical functionality without over-specification. The privacy feature distinguishes this unit from basic sub stations—it prevents the common scenario where master station operators can listen to ambient activity during idle periods, addressing privacy compliance in residential and healthcare settings. The AX-AN supports scaled deployments with clean cabling and straightforward mounting.
Technical Highlights:
- Privacy Isolation: Unlike open sub stations, the AX-AN blocks master station monitoring during receive mode, critical for HIPAA-adjacent environments and resident privacy expectations
- Extended Wiring Reach: The 980-foot Cat-5e support eliminates repeater requirements in typical building layouts, reducing system complexity and installation cost
- Dual Wiring Support: Compatibility with both structured Cat-5e and legacy 2-conductor wire simplifies retrofits into buildings with existing low-voltage infrastructure
Deployment Considerations:
- Confirm master station model (AX-8M, AX-8MV, or AX-8MV-W) capacity before specifying sub station count; expansion beyond 8 units requires AX-16SW selector card
- Plan wiring runs carefully—while 980 feet is supported, voltage drop on 2-conductor wire at maximum distance may reduce audio clarity; Cat-5e preferred for runs beyond 500 feet
- Specify surface mount (rather than semi-flush alternatives like AX-B) when renovation costs or timeline constraints favor expedited installation
The AX-AN is a reliable choice for buildings requiring privacy-protected intercom endpoints without video capability. Its combination of hands-free operation, privacy blocking, and straightforward installation makes it a practical fit for apartment buildings, office common areas, and service facilities where cost-per-unit and installation speed matter as much as feature breadth.
