Detects the sound of your doorbell ringing and alerts you via a Bellman Receiver
The Bellman Visit Door Transmitter is the part of the Bellman Visit system alerting you to the doorbell. The installation is extremely simple, simply attach the Door transmitter near the doorbell or intercom telephone. It is activated by both mechanical/electrical doorbells and intercom telephones.
When activated, the Door transmitter sends a radio signal to the Bellman Visit Receiver for clear alerting!
*NOTE: the Bellman Door Transmitter requires at least ONE Bellman Visit Receiver to operate.
