Abstract

PURPOSE: To decrease the number of the receiving device and other component parts per circuit and thus to reduce the cost by giving the time-division monitor to the information given from more than one unit of the transmitting device.
CONSTITUTION: Monitored transmitting devices 11W13 are connected to the receiving device via communication circuits 23W25 used for the system to monitor the prevention against the fire and burglar of the distant building. Then the following circuits are provided: signal detection circuit groups 31W33 to receive the repetitive serial block signal sent via circuits 23W25 and to detect the presence or absence of the signal; selection gate groups 34W36 to select one optional signal among the output signals; series-parallel converter circuit 38 to receive the output signals and to convert the repetitive block signal into the parallel signal through identification between the start and the end of the block; register groups 40W43 to memorize the output signals sent from circuit 38; and address register circuit 44 to transmit the selection signal to gate circuits 34W36 respectively. As a result, the number of the receiving device and other component parts can be reduced per circuit thus to reduce the cost by giving the time-division monitor to the information given from more than one unit of the transmitting device.
