To receive notifications, place the Medallion™ Series TransMATTer™ Transmitter under a doormat or bedside rug. Weight activated, it sends a wireless signal to any Medallion™ Series Receiver when a person enters or exits a room, or when someone such as a child, elderly individual or patient gets out of bed. As a result, it is ideal for use not only in homes, but also in hospitals, nursing facilities and even noisy business settings.
