信、水噴霧器Ｖ２１への放水用電源供給を実行させる。Next, the operation will be described. At the time of water discharge control, the disaster prevention receiver C0 transmits a water discharge command to the corresponding relay device, for example, the relay device C2, on the communication line S1, outputs a water discharge instruction on the common signal line S2, and further outputs a corresponding individual signal line, for example, an individual signal line. A water discharge instruction is output on the signal line S32. On the side of the relay device that has been requested to discharge water, for example, the relay device C2, the communication control means 21, the common signal receiving means 22, and the individual signal receiving means 23 receive a water discharge request, and the majority decision of the three means is determined by the water discharge determining means 24. The water spray supply power supply 25 is used to supply power to the water spray power supply path S52. The communication control means 21 transmits a water discharge command to a corresponding water spray control terminal, for example, the water spray control terminal T21, using the transmission line S42. The water discharge command is received by the transmission control means M21 in the water spray control terminal T21, and the power supply for water discharge to the water sprayer V21 is executed.

ため、放水を防止することが出来る。As described above, since the control instructions are multiplexed in each control stage, the water discharge can be prevented even if a single failure occurs and a wrong water discharge request is output. For example, the communication control unit 11 in the relay device C1
Even if a U runaway occurs and a water discharge instruction is output to the water discharge determination means 14, the water discharge determination means 14
Since the individual signal receiving means 13 is in the water discharge prohibition state, power is not supplied to the water spray power supply path S51 by majority decision. Further, even when the communication control unit 11 issues a water discharge instruction to the water spray control terminals T11 to T1a, the required power supply is not added to the water spray power supply path S51, so that water discharge can be prevented.
