IR204ETS Master Intercom Station

The Alpha Communications® IR204ETS are surface mounted (or optional desk mounted) intercom master stations which combine modern styling with ease of operation to provide natural, clear voice communication and monitoring of a remote intercom station. The attractive white, high-impact, ABS plastic faceplate blends with any decor. The advanced circuitry and versatility permits use in large variety of specialized intercom applications.

A built-in Toggle Switch enables the station to stay in the 'Listen' mode. Simply depressing the 'Talk' button, or depressing the optional model ST-FOOT foot switch will override the 'Listen' mode and place the station in 'Talk' mode. The Door button is not usually used for these applications, but it can be used for another signaling purpose if needed.
