Push button controlled wireless transmitters send digitally encoded signals to a plug-in receiver/signaling device. The receiver/signaling device has a microprocessor suitably programmed to respond to signals from a transmitter bearing the discrete address of the receiver, and to decode a transmitter identification code. Thereupon the microprocessor supplies an audio output circuit with signals to simulate selectively mechanical front or back door chimes, and supplies signals to energize a strobe lamp to emit bursts of multiple flashes, the number of flashes in a burst identifying the specific transmitter, whereby a person with a hearing deficiency is informed as to which transmitter is being actuated.

Des émetteurs sans fil commandés par boutons-poussoirs transmettent des signaux codés numériquement à un dispositif de réception/signalisation enfichable. Ce dispositif comporte un microprocesseur programmé de façon à répondre aux signaux transmis par un émetteur qui contiennent l'adresse discrète du récepteur, et pour décoder les codes d'identification d'émetteur. Ce microprocesseur transmet à un circuit de sortie audio des signaux simulant sélectivement des carillons mécaniques de porte avant ou arrière et transmet des signaux d'alimentation à une lampe émettrice de salves d'éclairs, le nombre d'éclairs dans une salve identifiant l'émetteur, de sorte qu'une personne à déficience auditive peut identifier l'émetteur des signaux.
