Bellman & Symfon Visit Multi-Purpose/Telephone Transmitter (BE1123)

The Bellman Visit Telephone Transmitter lets you know if the telephone or TTY is ringing, or if someone has opened a door/window. It connects quickly and easily: just plug it into any telephone jack within 28 meters (95 feet) of your Bellman Visit receiver. You can also connect the transmitter to a magnetic switch, which detects a door or window opening. The unit is powered by a long-lasting (three-year life) 9-volt alkaline battery.
