。[Prior Art and Problems to be Solved by the Invention] Hitherto, many gas-based fire extinguishing devices using, for example, fluorocarbon gas as an extinguishing medium have been put to practical use because of their high extinguishing performance. However, since chlorofluorocarbon gas causes destruction of the ozone layer in the atmosphere, we have not proposed using CO gas instead of chlorofluorocarbon gas in the near future.

については十分な安全対策が要請される。By the way, if C02 gas is released as a fire extinguishing gas into the entire protected area such as a building, there is a fatal problem that if there are any people left in the protected area, the C02 gas will suffocate them. Sufficient safety measures are required to prevent accidental release of fire extinguishing gas.

である。[Means for Solving the Problems] The present invention for solving the above-mentioned problems sends a starting gas for destruction from the starting gas discharge means to the fire extinguishing gas discharge part of the gas-based fire extinguishing means when a fire occurs. In a gas-based fire extinguishing system that sends extinguishing gas from a fire extinguishing gas to a protected area to extinguish a fire, the starting gas is placed in a gas flow path between the extinguishing gas discharge means and the extinguishing gas discharge part, and the starting gas is directed to the extinguishing gas discharge part side or to the atmosphere. A switching means for switching, a normal starting means for sending a normal starting signal, an abnormality detecting means for detecting an abnormal state of this device and sending an abnormality detection signal, and a normal starting signal for determining the normal starting signal and the abnormality detection signal. a discrimination control means that outputs an operation prohibition signal to the starting gas releasing means when the starting gas is released to zero when the starting gas is released, and outputting an operation prohibition signal to the starting gas releasing stage f and the switching means when an abnormality detection signal is input; The gas-based fire extinguishing apparatus is characterized by comprising a drive means for switching the switching means to the extinguishing gas discharge side or the atmosphere side in response to a starting gas release signal and an operation prohibition signal.

ガス放出信号を起動ガス放出手段に出力する。The gas fire extinguishing system according to the present invention sends a starting gas for destruction from the starting gas discharge means to the fire extinguishing gas discharge part of the gas fire extinguishing means and sends fire extinguishing gas from the gas fire extinguishing means to the protected compartment to extinguish the fire when a fire occurs. For example, when a fire occurs in a protected area, the normal starting means outputs a normal starting signal to the discrimination control means, and the discrimination output means determines that this input signal is a normal starting signal rather than an abnormality detection signal. A starting gas release signal is output to the starting gas releasing means.

ようになっている。The starting gas releasing means supplies the starting gas for destruction via the switching means (in an initial state, the switching means communicates the starting gas from the starting gas releasing means to the extinguishing gas discharge part of the gas-based fire extinguishing means). ), the fire extinguishing gas is spouted to the fire extinguishing gas discharge section, and the fire extinguishing gas is spouted from the fire extinguishing gas discharge section, which had previously been prohibited from spouting, into the protected area.

は異常検出信号を判別制御手段に出力する。On the other hand, for example, even though a fire has occurred in the protected area, the presence of personnel, for example, a ground fault due to the intrusion of rainwater, for example, a short circuit of the signal line due to a mistake on the part of the city; When the abnormality detection means detects an abnormality such as the presence of a person in the protected area despite the fact that a fire has occurred in the protected area, the abnormality detection means outputs an abnormality detection signal to the discrimination control means.
判別制御手段は、入力信号が通常起動信号でなくて前記
異常検出信号であると、？４別すると動作禁止信号を起
動ガス放出手段と駆動手段とに出力する。The determination control means determines whether the input signal is not the normal activation signal but the abnormality detection signal. 4, an operation prohibition signal is output to the starting gas discharge means and the drive means.
動作禁止手段の入力により切換手段は、起動ガス放出手
段からのガス流路を大気側に変換する。Upon input from the operation inhibiting means, the switching means converts the gas flow path from the starting gas discharge means to the atmosphere side.

段が動作することはない。As a result, despite the above-mentioned various conditions, even if an operation to emit extinguishing gas from the starting gas releasing means to blow out the extinguishing gas, for example, an operation of turning on the starting switch, the starting gas releasing means Since the operation prohibition signal is output to the starting gas, the starting gas is not discharged from the starting gas discharge means to the gas fire extinguishing means. As a result, it is prevented that extinguishing gas is released into the protected compartment and endangers personnel despite the presence of personnel in the protected compartment. Furthermore, even though an operation prohibition signal is output to this starting gas releasing means, the starting gas releasing means operates for some reason, and the starting gas is discharged toward the switching means due to the operation of the starting gas releasing means. Also, since the switching means is switched between the wave path and the atmosphere side by the driving means inputting the operation prohibition signal, the starting gas discharged from the starting gas discharge means is discharged to the atmosphere side by the switching means, and the gas system Fire extinguishing means will not be activated.

スを放出することか皆無になる。As described above, in this gas-based fire extinguishing system, a switching means is provided in the flow path of the starting gas to be released from the starting gas releasing means to the gas-based fire extinguishing means, and a switching means is provided in the flow path through which the starting gas flows from the starting gas releasing means to the gas-based fire extinguishing means. Even if the startup gas discharge stage performs a startup gas discharge operation despite the output of Since the fire extinguishing gas is discharged to the side, a double safety measure is taken.Therefore, even if there are personnel in the protected area, there is no chance of accidentally releasing fire extinguishing gas. become.
