Alpha Communications IS204A 4-wire Intercom Station

Product Description

The ALPHA COMMUNICATIONS IS204A is a 4-wire audio-only intercom station designed for surface or flush mount installation in residential and light commercial intercom systems. Built with a plastic housing, this station serves as a call or talk point within a wired intercom network, allowing voice communication between rooms, entry points, or building zones. It ships as a single unit and is installed by low-voltage technicians or electricians working on structured wiring and intercom systems.

Its dual mount design accommodates surface mounting on walls or flush mounting in a standard electrical box, giving installers flexibility in both new builds and retrofit scenarios. This station is appropriate for residential hallways, apartments, offices, and entry points where simple two-way voice communication is the primary requirement. It is commonly specified in multi-station intercom systems requiring dependable, straightforward audio performance.

Installation Notes

Installation should be performed by a licensed low-voltage technician or electrician in accordance with applicable NEC guidelines for low-voltage wiring. De-energize the intercom system at the master power supply before connecting or disconnecting any station wiring. Verify that the existing wiring run supports a 4-wire configuration before installation. Flush mount installations require a compatible electrical box roughed in at the desired location prior to mounting the station.
