...The wireless set consists of the wireless gong receiver and the wireless motion detector. The motion detector can be installed directly above the door or on the ceiling. It operates using either batteries or the included power adapter. The wireless gong can be placed anywhere and requires power from the included power adapter. When a person enters, the motion detector will send a signal to the wireless gong, which will then emit the selected tone. It is also known as the Schupafon sound.
