ABSTRACT:
A plurality of remote stations are sequentially addressed by a master controller to ascertain the status of associated sensing devices. The addresses are each comprised of a sequence of sinusoidal waveforms which are counted by the remote stations and compared with a preselected station number. Each addressed station responds by driving a communication line to a low voltage level for a time interval determined by the status of its associated sensing device.
