摘要

PROBLEM TO BE SOLVED: To simultaneously give a siren messages to plural different slave stations in a municipalities disaster prevention administration radio fixed system which includes plural slave stations of different siren systems. ;SOLUTION: A slave station 5 of a motor siren system and a slave station 8 of a pseudo siren system are selected by the console 1 of a master station. Based on the selection of these stations 5 and 8, a signal output part 2 generates the control signal data including a motor siren system slave station control signal and a pseudo siren system slave station control signal and outputs the data to a radio device 3. The device 3 modulates the input control signal data and transmits this data as the radio data via a transmitting antenna 4. The stations 5 and 8 receive the radio data via the receiving antennas 6 and 9 respectively and demodulate the control signals included in the radio data and addressed to their own stations. Then, both stations 5 and 8 output the siren sounds through trumpet speakers 7 and 10 respectively.;COPYRIGHT: (C)1997,JPO
