Bellman Visit Doorbell Ringer and Signaler Alert Transmitter
The Swedish designed Door Chime Transmitter in the Bellman Visit Alerting System notifies you to the doorbell. When activated, the Door Chime Transmitter sends a signal to the Bellman Visit receiver(s) for clear alerting. To install, simply attach the transmitter near the doorbell or intercom.
Approximate operating range in open field about 100 feet (33 yards); walls and other large objects may greatly affect coverage. Includes one 9V battery.
What else do I need to make this work?
In order to be notified, you will need to purchase a receiver that lets you know when the signaler or transmitter is activated
