Detects the sound of your doorbell ringing and alerts you via the Bellman Flash 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 Flash Receiver for clear alerting!
