ABSTRACT:
A wireless signaling between one or more remote locations and a central location includes a transmitter at each remote location and switches for providing signals indicating status information on each remote location. A logic circuit coupled to the switches and to the transmitter provide signals effecting transmission of a signal modulated to uniquely identify the remote location and the status represented by the switches. A receiver at the central location is coupled to a second logic circuit for decoding the signals received from the transmitter and is coupled to indicators for providing an indication of the status at the first location.
