Abstract
A plurality of receivers which can be respectively addressed by addressing pulses provide reply pulses on a separate reply signal bus indicative of a single digit, or multi-digit binary response condition. To permit extended indication, the central station includes a holding stage which holds the output received from the reply receivers for the duration of a selection cycle during which the plurality of loads can be addressed, for example during a predetermined counted number of such cycles or during a predetermined counted number of pulses to permit averaging-type instruments to respond to said number of pulses --if present--or to permit extended indication of single digit binary output--if present.
