The Model Nutone NDB300 Series Intercom Door Station with Bell Button is a voice communications interface that mounts adjacent to a primary entry door. This model is compatible with the NM Series of Master Music/Communication Systems ONLY. For older systems such as the IM3303 Master Intercom, please order our retrofit Intercom Station.
Pressing the lighted bell button will trigger the doorbell chime on the Music/Communications system (if equipped) to announce a visitor. Two-way voice communication with the resident occurs through the unit’s built-in speaker.
The faceplate of the NDB300 Intercom Door Station with Bell Button has an antique, white or polished brass finish. The door station mounts recessed in the wall.
