Abstract
To provide a technique that can suppress an increase of a time taken for establishment of synchronization.SOLUTION: A fifth fire alarm device 600e transmits a synchronization signal at a timing synchronized with a first relay device 700a side. A sixth fire alarm device 600f receives the synchronization signal from the fifth fire alarm device 600e to synchronize the fifth fire alarm device 600e. The fifth fire alarm device 600e transmits a synchronization signal containing information on correction of the synchronized timing if the timing synchronized with the first relay device 700a side has to be corrected.SELECTED DRAWING: Figure 1
