This transmitter with doorbell button is for homes that have a doorbell system with a low voltage chime already installed and has a doorbell button. It easily wires into your existing doorbell and is activated by the same current. Whenever a visitor presses the button, a signal is sent to any Medallion Series Receiver, which will alert you by flashing light or vibration.

With the Medallion Series you get million-code technology, which means your system will never get a false alert from a neighboring radio frequency signaling system. It's ideal for apartments, dorms, condos and hotels, as well as single-family homes.

Features:

• Up to 500ft range
• Operates on doorbell's electrical circuit, no batteries required
