Alpha Communications 3403 3 Wire Surface Mount Intercom Station

Product Description

The ALPHA COMMUNICATIONS 3403 is a 3-wire surface-mount intercom station designed for audio-only intercom systems. It mounts directly to a wall or door frame surface without requiring an in-wall rough-in box, making installation straightforward in retrofit and new-construction applications alike. The 3-wire configuration keeps wiring simple and compatible with standard audio intercom infrastructure. Licensed low-voltage technicians and security installers typically handle deployment of this station in residential and light commercial settings.

This station is suited for audio-only intercom installations where video capability is not required. Common applications include apartment entry systems, office doorways, and multi-unit residential buildings. It functions as a call station or substation within a broader audio intercom network. The surface-mount design makes it a practical choice when in-wall installation is not feasible or when adding a station to an existing system.
