Bellman Symfon Visit Push Button Transmitter

When the Push Button Transmitter is pressed， a radio signal is sent to any Bellman Visit receiver. Attach the Push Button Transmitter outside your door to use as a doorbell， or indoors to get someone's attention (neck lanyard included). For indoor use and outdoors in sheltered locations. Includes one PX28A alkaline battery.

In order to be notified， you will need to purchase a receiver that lets you know when the signaler or transmitter is activated.
