What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This is a small external microphone that plugs into a Bellman & Symfon Door Transmitter, extending its ability to pick up sounds from a greater distance or from a secondary source like an intercom. It's useful for someone who is deaf or hard of hearing and needs their alerting system to reliably detect a doorbell or intercom signal that the built-in microphone can't adequately capture from its installed position. This is purely an accessory — it does nothing on its own and requires a compatible Bellman & Symfon Door Transmitter already installed and working. Make sure your specific Door Transmitter model supports an external microphone input before purchasing, as not all Bellman products share accessories.
