Abstract

[Problem] To shorten the delay time that is taken before a countdown stop process is carried out at a fire alarm receiver when said countdown stop process is instructed remotely by a user using an emergency stop switch. [Solution] A fire alarm receiver 10 starts a countdown upon receipt of either a sensor signal which is outputted from a fire sensor 2 or an activation signal which is outputted from a manual discharge switch 6. Upon receipt of a stop signal which is outputted from an emergency stop switch 7 prior to the end of the countdown, the countdown is stopped. When the countdown ends, a fire extinguishing gas is discharged from a jet head 3. The fire alarm receiver 10 receives the stop signal outputted from the emergency stop switch 7 with higher priority than the sensor signal outputted from the fire sensor 2.

Description

火災受信機Fire receiver
　本発明は、火災受信機に関する。 The present invention relates to a fire receiver.
　従来、二酸化炭素等の消火ガスを放出して火災を消火するガス系消火設備が知られている。例えば、特許文献１には、防護区画の各々に、火災を感知するための火災感知器と、消火ガスを放出するための噴射ヘッドと、消火ガスの放出を手動で行ったり、消火ガスの放出を非常停止したりするための操作箱とを備えるガス系消火設備が記載されている。このガス系消火設備はさらに、防護区画の外部に、消火ガスを貯蔵するための消火ガス貯蔵容器と、このガス系消火設備を制御する制御盤とを備えている。この制御盤は、ある防護区画において火災感知器により火災が感知されたり、操作箱の消火ガス放出スイッチが操作されたりすると、カウントダウンを開始し、その残り時間を盤面と操作箱に表示させる。そして、カウントダウンが終了すると、消火ガス貯蔵容器の開放弁を駆動して、対象の防護区画の噴射ヘッドから消火ガスを放出させる。 Conventionally, gas-based fire extinguishing equipment that releases fire extinguishing gas such as carbon dioxide to extinguish a fire is known. For example, in Patent Document 1, a fire detector for detecting a fire, an injection head for discharging a fire extinguishing gas, and a fire extinguishing gas are manually discharged or released in each of the protected areas. A gas-based fire extinguishing system equipped with an operation box for making an emergency stop is described. The gas-based fire extinguishing equipment is further provided with a fire-extinguishing gas storage container for storing the fire-extinguishing gas and a control panel for controlling the gas-based fire-extinguishing equipment outside the protected area. When a fire is detected by a fire detector or the fire extinguishing gas release switch of the operation box is operated in a certain protected area, the control panel starts a countdown and displays the remaining time on the board and the operation box. Then, when the countdown is completed, the open valve of the fire extinguishing gas storage container is driven to release the fire extinguishing gas from the injection head of the target protected area.
特開２０１７－１８３３７号公報Japanese Unexamined Patent Publication No. 2017-18337
　上記のガス系消火設備では、操作箱に表示される残り時間が零になる前に非常停止操作を行ったとしても、信号の伝送遅延や制御盤における処理の遅れにより、制御盤におけるカウントダウンの停止処理が間に合わず、噴射ヘッドから消火ガスが放出されてしまう場合があった。 In the above gas-based fire extinguishing equipment, even if the emergency stop operation is performed before the remaining time displayed on the operation box becomes zero, the countdown on the control panel is stopped due to the signal transmission delay and the processing delay on the control panel. In some cases, the treatment was not in time and the fire extinguishing gas was released from the injection head.
　本発明は、このような事情に鑑みてなされたものであり、利用者が緊急停止スイッチを用いてカウントダウンの停止処理を遠隔で指示したときに、当該処理が火災受信機において実行されるまでに要する遅延時間を短縮することを目的とする。 The present invention has been made in view of such circumstances, and when a user remotely instructs a countdown stop process using an emergency stop switch, the process is executed by the fire receiver. The purpose is to reduce the required delay time.
　上記の課題を解決するため、本発明に係る火災受信機は、防護区画に設置された端末装置から信号を受信し、当該信号に応じた処理を実行する火災受信機であって、前記端末装置は、前記防護区画に設置され、感知器信号を出力する火災感知器と、前記防護区画に設置された噴射ヘッドから消火ガスを放出することを指示するための手動放出スイッチであって、利用者により操作されると第１起動信号を出力する手動放出スイッチと、前記噴射ヘッドからの消火ガスの放出を緊急停止するための緊急停止スイッチであって、利用者により操作されると停止信号を出力する緊急停止スイッチとを含み、前記火災受信機は、前記感知器信号又は前記第１起動信号を受信すると、カウントダウンを開始し、前記カウントダウンの終了前に前記停止信号を受信すると、前記カウントダウンを停止し、前記カウントダウンが終了すると、前記噴射ヘッドから消火ガスを放出させ、前記停止信号を前記感知器信号よりも優先して受信することを特徴とする。 In order to solve the above problems, the fire receiver according to the present invention is a fire receiver that receives a signal from a terminal device installed in a protected area and executes processing according to the signal. Is a fire detector installed in the protected area to output a sensor signal, and a manual release switch for instructing the release of fire extinguishing gas from the injection head installed in the protected area. A manual release switch that outputs a first start signal when operated by, and an emergency stop switch for emergency stopping the release of fire extinguishing gas from the injection head, and outputs a stop signal when operated by the user. The fire receiver starts the countdown when it receives the detector signal or the first start signal, and stops the countdown when it receives the stop signal before the end of the countdown. When the countdown is completed, the fire extinguishing gas is discharged from the injection head, and the stop signal is received with priority over the sensor signal.
　好ましい態様において、前記火災受信機は、前記感知器信号又は前記第１起動信号に応じた処理よりも、前記停止信号に応じた処理を優先して実行してもよい。 In a preferred embodiment, the fire receiver may execute the process corresponding to the stop signal with priority over the process corresponding to the sensor signal or the first start signal.
　さらに好ましい態様において、前記火災受信機は、前記第１起動信号と前記停止信号を、前記防護区画に設置された第１のガス消火制御装置を介して受信し、前記第１のガス消火制御装置に対応づけて動作モードを記憶する記憶部を備え、前記記憶部に記憶される動作モードが自動モードである場合には、前記感知器信号又は前記第１起動信号を受信すると、前記カウントダウンを開始し、前記記憶部に記憶される動作モードが手動モードである場合には、前記第１起動信号を受信したときのみ、前記カウントダウンを開始し、前記記憶部において、前記防護区画に設置された第２のガス消火制御装置と対応づけて、前記第１のガス消火制御装置と異なる動作モードが記憶されている場合に、前記第１起動信号を受信したときのみ、前記カウントダウンを開始するようにしてもよい。 In a more preferred embodiment, the fire receiver receives the first start signal and the stop signal via the first gas fire extinguishing control device installed in the protected area, and the first gas fire extinguishing control device. When the operation mode stored in the storage unit is the automatic mode, the countdown is started when the sensor signal or the first activation signal is received. When the operation mode stored in the storage unit is the manual mode, the countdown is started only when the first activation signal is received, and the storage unit is installed in the protection zone. When the operation mode different from that of the first gas fire extinguishing control device is stored in association with the gas fire extinguishing control device of 2, the countdown is started only when the first start signal is received. May be good.
　さらに好ましい態様において、前記端末装置は、第２起動信号が入力されると、前記噴射ヘッドから消火ガスが放出されることを警告する警告装置をさらに含み、前記第１のガス消火制御装置は、前記手動放出スイッチから出力される第１起動信号を前記火災受信機に対して中継し、前記緊急停止スイッチから出力される停止信号を前記火災受信機に対して中継し、前記火災受信機から出力される第２起動信号を受けて前記警告装置を起動する入出力制御部と、前記噴射ヘッドから消火ガスが放出されるまでの時間を表示する表示部とを備えてもよい。 In a more preferred embodiment, the terminal device further includes a warning device that warns that a fire extinguishing gas is released from the injection head when a second start signal is input, and the first gas fire extinguishing control device is The first start signal output from the manual release switch is relayed to the fire receiver, the stop signal output from the emergency stop switch is relayed to the fire receiver, and the fire receiver outputs the stop signal. An input / output control unit that activates the warning device in response to the second activation signal to be generated, and a display unit that displays the time until the fire extinguishing gas is discharged from the injection head may be provided.
　本発明によれば、利用者が緊急停止スイッチを用いてカウントダウンの停止処理を遠隔で指示したときに、当該処理が火災受信機において実行されるまでに要する遅延時間を短縮することができる。 According to the present invention, when a user remotely instructs a countdown stop process using an emergency stop switch, the delay time required for the process to be executed in the fire receiver can be shortened.

　消火ガス貯蔵容器１１は、二酸化炭素やハロンガス等の消火ガスを貯蔵する容器である。消火ガス貯蔵容器１１の各々は、容器弁を介して集合配管に接続されている。この集合配管は、防護区画ごとに設置される選択弁１２を介して分枝されている。分枝された配管は、それぞれ異なる防護区画に設置された噴射ヘッド３に接続されている。 The fire extinguishing gas storage container 11 is a container for storing fire extinguishing gas such as carbon dioxide and halon gas. Each of the fire extinguishing gas storage containers 11 is connected to the collecting pipe via a container valve. This collecting pipe is branched via a selection valve 12 installed in each protection section. The branched pipes are connected to injection heads 3 installed in different protected sections.
　起動用ガス容器１３は、消火ガス貯蔵容器１１の容器弁と選択弁１２を開放するための起動用ガスを貯蔵する容器である。起動用ガス容器１３は、選択弁１２ごとに（言い換えると、防護区画ごとに）設置されている。起動用ガス容器１３の各々は、消火ガス貯蔵容器１１の容器弁と、対応する選択弁１２とに配管を介して接続されている。また、起動用ガス容器１３の各々の容器弁ソレノイドは、中継器１４を介して信号線で火災受信機１０と接続されている。火災受信機１０から中継器１４に起動信号が入力されると、中継器１４はこの容器弁ソレノイドを作動させ、起動用ガス容器１３から起動用ガスを放出させる。その起動用ガスのガス圧により、消火ガス貯蔵容器１１の容器弁と、対応する選択弁１２を開放する。その結果、消火ガス貯蔵容器１１に貯蔵された消火ガスは、当該選択弁１２により分枝される配管を通って、当該配管に接続されている噴射ヘッド３から放出される。 The starting gas container 13 is a container for storing starting gas for opening the container valve of the fire extinguishing gas storage container 11 and the selection valve 12. The starting gas container 13 is installed for each selection valve 12 (in other words, for each protection zone). Each of the starting gas containers 13 is connected to the container valve of the fire extinguishing gas storage container 11 and the corresponding selection valve 12 via a pipe. Further, each container valve solenoid of the starting gas container 13 is connected to the fire receiver 10 by a signal line via the repeater 14. When a start signal is input from the fire receiver 10 to the repeater 14, the repeater 14 operates the container valve solenoid to release the start gas from the start gas container 13. The gas pressure of the starting gas opens the container valve of the fire extinguishing gas storage container 11 and the corresponding selection valve 12. As a result, the fire extinguishing gas stored in the fire extinguishing gas storage container 11 is discharged from the injection head 3 connected to the pipe through the pipe branched by the selection valve 12.
　次に、ガス消火制御装置９の具体的な構成について説明する。 Next, the specific configuration of the gas fire extinguishing control device 9 will be described.

Among the operation modes selected by the mode selection switch 93, in the automatic mode, when the fire detector 2 installed in the protected area detects a fire, or the manual release switch 6 installed in the protected area is used. This is an operation mode in which a fire extinguishing gas is released into the protected area when operated by the user. On the other hand, the manual mode is an operation mode in which the fire extinguishing gas is discharged into the protected area only when the manual release switch 6 installed in the protected area is operated by the user. The operation mode selected by using the mode selection switch 93 is associated with the address of the gas fire extinguishing control device 9 and stored in the protection zone setting table TBL2 described later.

　次に、制御部１０１の詳細について説明する。
　制御部１０１のメモリ１０１２は、上記の制御プログラムＰに加えて、連動制御テーブルＴＢＬ１と防護区画設定テーブルＴＢＬ２を記憶する。 Next, the details of the control unit 101 will be described.
The memory 1012 of the control unit 101 stores the interlocking control table TBL1 and the protection zone setting table TBL2 in addition to the control program P described above.
　連動制御テーブルＴＢＬ１は、火災受信機１０においてイベントが発生した時に、連動して実行すべき処理を特定するために参照されるテーブルである。この連動制御テーブルＴＢＬ１には、火災受信機１０で発生するイベントごとに、実行すべき処理が対応付けられている。例えば、動作モードが自動モードである防護区画に設置されている火災感知器２から最初の作動信号を受信するというイベントに対して、盤面の警報動作という処理とベル４の間欠鳴動という処理が対応付けられている。また、別の例として、カウントダウンの終了というイベントに対して、中継器１４に起動信号を出力するという処理が対応付けられている。 The interlocking control table TBL1 is a table that is referred to in order to specify the processing to be interlocked and executed when an event occurs in the fire receiver 10. The interlocking control table TBL1 is associated with a process to be executed for each event that occurs in the fire receiver 10. For example, in response to the event of receiving the first operation signal from the fire detector 2 installed in the protected area where the operation mode is the automatic mode, the process of alarm operation on the board and the process of intermittent ringing of the bell 4 correspond. It is attached. Further, as another example, a process of outputting a start signal to the repeater 14 is associated with the event of the end of the countdown.
　防護区画設定テーブルＴＢＬ２は、防護区画単位で連動する機器を特定するために参照されるテーブルである。また、このテーブルは、防護区画の動作モードを判定するために参照されるテーブルである。この防護区画設定テーブルＴＢＬ２には、防護区画のＩＤごとに、連動する火災感知器２、ガス消火制御装置９及び中継器１４のアドレスが対応付けられている。また、ガス消火制御装置９のアドレスごとに、連動するベル４、ストロボ５、手動放出スイッチ６、緊急停止スイッチ７及び放出表示灯８のアドレス並びに動作モードが対応付けられている。このテーブルでは、防護区画のＩＤとその動作モードが、ガス消火制御装置９のアドレスを介して対応付けられている。 The protected zone setting table TBL2 is a table that is referred to for specifying the devices that are linked in each protected zone. Further, this table is a table referred to for determining the operation mode of the protected area. The protected area setting table TBL2 is associated with the addresses of the interlocking fire detector 2, the gas fire extinguishing control device 9, and the repeater 14 for each ID of the protected area. Further, for each address of the gas fire extinguishing control device 9, the addresses of the interlocking bell 4, the strobe 5, the manual release switch 6, the emergency stop switch 7, and the release indicator light 8 and the operation mode are associated with each other.

Then, the edited protected zone setting table TBL2 is stored in the memory 1012 of the fire receiver 10 via a storage medium such as an SD card or wired or wireless communication.
　次に、プロセッサ１０１１が上記の制御プログラムＰを実行することで実現する機能について説明する。
　プロセッサ１０１１は、上記の制御プログラムＰを実行することで、受信部１０５、動作モード判定部１０６、処理特定部１０７及び処理実行部１０８の各機能を実現する。以下、各機能について説明する。 Next, the function realized by the processor 1011 by executing the above-mentioned control program P will be described.
By executing the control program P, the processor 1011 realizes the functions of the receiving unit 105, the operation mode determining unit 106, the processing specifying unit 107, and the processing executing unit 108. Each function will be described below.
　受信部１０５は、火災感知器２とガス消火制御装置９の各々からポーリング／セレクティング方式で信号を受信する。具体的には、火災感知器２とガス消火制御装置９に対して通常ポイントポーリングを行って、応答した装置から信号を収集する。 The receiving unit 105 receives signals from each of the fire detector 2 and the gas fire extinguishing control device 9 by a polling / selecting method. Specifically, the fire detector 2 and the gas fire extinguishing control device 9 are normally point polled, and a signal is collected from the device that responded.
　ここで、通常ポイントポーリングとは、建物Ｂに設置されている火災感知器２とガス消火制御装置９を複数のグループに分け、グループ単位で順番に行われるポーリングである。各通常ポイントポーリングでは、グループに属する装置の各々に対して通常応答タイミングが設定される。出力すべき信号を有する装置は、受信部１０５から出力されるポーリング信号に応答して、自装置に設定された応答タイミングにおいて信号とアドレスを出力する。また、各通常ポイントポーリングでは、建物Ｂに設置されているすべてのガス消火制御装置９のみを含む１つのグループに対して、特別応答タイミングが設定される。出力すべき信号を有するガス消火制御装置９は、受信部１０５から出力されるポーリング信号に応答して、当該グループに設定された応答タイミングにおいてアドレスのみを出力する。ここで、ガス消火制御装置９用の特別応答タイミングを別途設定する理由は、ガス消火制御装置９から出力される停止信号を火災受信機１０が迅速に受信するためである。ガス消火制御装置９には火災感知器２よりも１台あたりにつき多くの応答タイミングが設定されるため、ガス消火制御装置９から出力される停止信号は火災感知器２から出力される作動信号と比較して、火災受信機１０により優先的に受信されることになる。 Here, the normal point polling is a polling in which the fire detector 2 and the gas fire extinguishing control device 9 installed in the building B are divided into a plurality of groups and are sequentially performed in each group. In each normal point poll, a normal response timing is set for each of the devices belonging to the group. The device having the signal to be output responds to the polling signal output from the receiving unit 105 and outputs the signal and the address at the response timing set in the own device. Further, in each normal point polling, a special response timing is set for one group including only all the gas fire extinguishing control devices 9 installed in the building B. The gas fire extinguishing control device 9 having a signal to be output responds to the polling signal output from the receiving unit 105 and outputs only the address at the response timing set in the group. Here, the reason for separately setting the special response timing for the gas fire extinguishing control device 9 is that the fire receiver 10 quickly receives the stop signal output from the gas fire extinguishing control device 9. Since the gas fire extinguishing control device 9 is set with more response timings per unit than the fire detector 2, the stop signal output from the gas fire extinguishing control device 9 is the operation signal output from the fire detector 2. In comparison, the fire receiver 10 preferentially receives the signal.
　図５は、この通常システムポーリングの一例を示すタイムチャートである。同図は、建物Ｂに設置されている火災感知器２とガス消火制御装置９を３つのグループに分け、グループ単位で順番に行われる通常ポイントポーリングＰＬ１、ＰＬ２及びＰＬ３を示している。通常ポイントポーリングＰＬ１では、グループに属する装置の各々に対して通常応答タイミングＴ０、Ｔ１、Ｔ２及びＴ３のいずれかが設定されている。また、すべてのガス消火制御装置９のみを含む１つのグループに対して、特別応答タイミングＴｇが設定されている。出力すべき信号を有する装置は、受信部１０５から出力されるポーリング信号Ｓ１に応答して、自装置に設定された応答タイミングにおいて応答する。 FIG. 5 is a time chart showing an example of this normal system polling. The figure shows the normal point polling PL1, PL2 and PL3 in which the fire detector 2 and the gas fire extinguishing control device 9 installed in the building B are divided into three groups and are sequentially performed in each group. In the normal point polling PL1, any of the normal response timings T0, T1, T2, and T3 is set for each of the devices belonging to the group. Further, a special response timing Tg is set for one group including only all gas fire extinguishing control devices 9. The device having the signal to be output responds to the polling signal S1 output from the receiving unit 105 at the response timing set in the own device.
　通常ポイントポーリングＰＬ２では、グループに属する装置の各々に対して通常応答タイミングＴ４、Ｔ５、Ｔ６及びＴ７のいずれかが設定されている。また、すべてのガス消火制御装置９のみを含む１つのグループに対して、特別応答タイミングＴｇが設定されている。出力すべき信号を有する装置は、受信部１０５から出力されるポーリング信号Ｓ２に応答して、自装置に設定された応答タイミングにおいて応答する。 In the normal point polling PL2, one of the normal response timings T4, T5, T6 and T7 is set for each of the devices belonging to the group. Further, a special response timing Tg is set for one group including only all gas fire extinguishing control devices 9. The device having the signal to be output responds to the polling signal S2 output from the receiving unit 105 at the response timing set in the own device.
　通常ポイントポーリングＰＬ３では、グループに属する装置の各々に対して通常応答タイミングＴ８、Ｔ９、Ｔ１０及びＴ１１のいずれかが設定されている。また、すべてのガス消火制御装置９のみを含む１つのグループに対して、特別応答タイミングＴｇが設定されている。出力すべき信号を有する装置は、受信部１０５から出力されるポーリング信号Ｓ３に応答して、自装置に設定された応答タイミングにおいて応答する。 In the normal point polling PL3, one of the normal response timings T8, T9, T10 and T11 is set for each of the devices belonging to the group. Further, a special response timing Tg is set for one group including only all gas fire extinguishing control devices 9. The device having the signal to be output responds to the polling signal S3 output from the receiving unit 105 at the response timing set in the own device.
　この通常ポイントポーリングの特別応答タイミングのいずれかで応答が行われると、受信部１０５は、当該応答を行ったガス消火制御装置９に対して状態確認セレクティングを行い、当該装置から信号を収集する。 When a response is made at any of the special response timings of the normal point polling, the receiving unit 105 performs a state confirmation selection on the gas fire extinguishing control device 9 that has made the response, and collects a signal from the device. ..
　なお、図５に示す通常ポイントポーリングＰＬの数と、各通常ポイントポーリングＰＬの通常応答タイミングＴの数はあくまで一例である。これらの数は、建物Ｂに設置される火災感知器２とガス消火制御装置９の台数に応じて適宜変更されてよい。例えば、火災感知器２とガス消火制御装置９が合計２５６台設置される建物Ｂでは、通常ポイントポーリングＰＬの数を「１６」とし、各通常ポイントポーリングＰＬの通常応答タイミングＴの数を「１６」としてもよい。
　以上が、受信部１０５についての説明である。 The number of normal point polling PLs shown in FIG. 5 and the number of normal response timings T of each normal point polling PL are merely examples. These numbers may be appropriately changed according to the number of fire detectors 2 and gas fire extinguishing control devices 9 installed in the building B. For example, in building B where a total of 256 fire detectors 2 and gas fire extinguishing control devices 9 are installed, the number of normal point polling PLs is set to "16", and the number of normal response timings T of each normal point polling PL is set to "16". May be.
The above is the description of the receiving unit 105.
　次に、動作モード判定部１０６は、防護区画設定テーブルＴＢＬ２を参照して、防護区画に設定された動作モードを判定する。 Next, the operation mode determination unit 106 determines the operation mode set in the protection zone with reference to the protection zone setting table TBL2.
　処理特定部１０７は、連動制御テーブルＴＢＬ１を参照して、火災受信機１０で発生したイベントに連動して実行すべき処理を特定する。そして、特定した処理の情報をバッファに格納する。バッファには、通常バッファと優先バッファの２種類がある。優先バッファには、カウントダウンを停止する処理の情報が格納され、通常バッファには、その他の処理の情報が格納される。ここで、優先バッファにカウントダウンを停止する処理の情報を格納する理由は、当該処理の実行を優先するためである。 The process specifying unit 107 refers to the interlocking control table TBL1 and specifies the process to be executed in conjunction with the event generated in the fire receiver 10. Then, the information of the specified process is stored in the buffer. There are two types of buffers, a normal buffer and a priority buffer. The priority buffer stores information on the process of stopping the countdown, and the normal buffer stores information on other processes. Here, the reason for storing the information of the process for stopping the countdown in the priority buffer is to give priority to the execution of the process.
　処理実行部１０８は、通常バッファ及び優先バッファに格納されている処理情報を読み出して、読み出した処理情報に示される処理を実行する。その際、処理実行部１０８は、通常バッファに格納されている処理情報よりも優先バッファに格納されている処理情報を優先して読み出す。具体的には、優先バッファに処理情報が格納された場合には、当該処理情報よりも前に通常バッファに処理情報が格納されていたとしても、優先バッファに格納された処理情報を先に読み出す。そのため、処理実行部１０８は、火災感知器２から出力される作動信号に応じた処理や手動放出スイッチ６から出力される起動信号に応じた処理よりも、緊急停止スイッチ７から出力される停止信号に応じた処理を優先して実行することになる。
　この処理実行部１０８は、連動して制御すべき処理を実行する際、防護区画設定テーブルＴＢＬ２を参照して、防護区画単位で連動する機器を特定する。 The processing execution unit 108 reads the processing information stored in the normal buffer and the priority buffer, and executes the processing indicated by the read processing information. At that time, the processing execution unit 108 preferentially reads the processing information stored in the priority buffer over the processing information stored in the normal buffer. Specifically, when the processing information is stored in the priority buffer, the processing information stored in the priority buffer is read first even if the processing information is stored in the normal buffer before the processing information. .. Therefore, the process execution unit 108 has a stop signal output from the emergency stop switch 7 rather than a process according to the operation signal output from the fire detector 2 or a process according to the start signal output from the manual release switch 6. The processing according to the above will be executed with priority.
When the process execution unit 108 executes the process to be controlled in conjunction with each other, the process execution unit 108 refers to the protected zone setting table TBL2 and specifies the device to be linked in each protected zone.
１－２．動作
　次に、ガス系消火設備１の動作について説明する。具体的には、火災受信機１０の受信部１０５が実行する受信動作と、ガス系消火設備１で行われる消火動作について説明する。 1-2. Operation Next, the operation of the gas-based fire extinguishing equipment 1 will be described. Specifically, the reception operation performed by the receiving unit 105 of the fire receiver 10 and the fire extinguishing operation performed by the gas-based fire extinguishing equipment 1 will be described.
１－２－１．受信動作
　図６は、火災受信機１０の受信部１０５が実行する受信動作を示すフローチャートである。
　同図に示す受信動作において受信部１０５は、まず、建物Ｂに設置されている火災感知器２とガス消火制御装置９により形成されるグループの番号を示す変数ｇを「０」に設定する（ステップＳａ１）。次に、設定されているグループ番号が示すグループに対して通常ポイントポーリングを実行する（ステップＳａ２）。この通常システムポーリングの特別応答タイミングで応答が行われると（ステップＳａ３のＹＥＳ）、受信部１０５は、当該応答を行ったガス消火制御装置９に対して状態確認セレクティングを行い、当該装置から信号を収集する（ステップＳａ４）。そして、ステップＳａ５に進む。一方、特別応答タイミングで応答が行われなかった場合には（ステップＳａ３のＮＯ）、ステップＳａ４を実行せずにステップＳａ５に進む。 1-2-1. Reception operation FIG. 6 is a flowchart showing a reception operation executed by the reception unit 105 of the fire receiver 10.
In the receiving operation shown in the figure, the receiving unit 105 first sets the variable g indicating the group number formed by the fire detector 2 and the gas fire extinguishing control device 9 installed in the building B to “0” ( Step Sa1). Next, normal point polling is executed for the group indicated by the set group number (step Sa2). When a response is made at the special response timing of this normal system polling (YES in step Sa3), the receiving unit 105 performs a state confirmation selection on the gas fire extinguishing control device 9 that has made the response, and signals from the device. (Step Sa4). Then, the process proceeds to step Sa5. On the other hand, if no response is made at the special response timing (NO in step Sa3), the process proceeds to step Sa5 without executing step Sa4.
　ステップＳａ５では、受信部１０５は、変数ｇを「１」インクリメントする。この結果、変数ｇがグループの総数を示す値Ｇを超えた場合には、受信部１０５はステップＳａ１に戻り、変数ｇを再び「０」に設定する。一方、変数ｇがグループの総数を示す値Ｇを超えない場合には、受信部１０５はステップＳａ２に戻り、設定されているグループ番号が示すグループに対して通常ポイントポーリングを実行する。
　以上が、火災受信機１０の受信部１０５が実行する受信動作についての説明である。 In step Sa5, the receiving unit 105 increments the variable g by "1". As a result, when the variable g exceeds the value G indicating the total number of groups, the receiving unit 105 returns to step Sa1 and sets the variable g to “0” again. On the other hand, if the variable g does not exceed the value G indicating the total number of groups, the receiving unit 105 returns to step Sa2 and normally performs point polling on the group indicated by the set group number.
The above is the description of the receiving operation executed by the receiving unit 105 of the fire receiver 10.
１－２－２．消火動作
　次に、ガス系消火設備１で行われる消火動作について説明する。具体的には、動作モードが自動モードに設定されている防護区画に対する消火動作について説明する。また、動作モードが手動モードに設定されている防護区画に対する消火動作について説明する。 1-2-2. Fire extinguishing operation Next, the fire extinguishing operation performed in the gas-based fire extinguishing equipment 1 will be described. Specifically, the fire extinguishing operation for the protected area in which the operation mode is set to the automatic mode will be described. In addition, a fire extinguishing operation for a protected area in which the operation mode is set to the manual mode will be described.
１－２－２－１．自動モード
　図７及び図８は、動作モードが自動モードに設定されている防護区画に対する消火動作の一例を示すシーケンス図である。
　動作モードが自動モードに設定されている防護区画（以下、本動作の説明において「防護区画Ｐ１」という。）において火災が発生し、発生した火災が、防護区画Ｐ１に設置されている火災感知器２により感知されると、当該火災感知器２は火災受信機１０に対して作動信号を出力する。この作動信号が入力された火災受信機１０の制御部１０１は（ステップＳｂ１）、火災受信機１０の火災灯１０２１を点灯させるとともに、ブザー１０３を鳴動させる（ステップＳｂ２）。その結果、監視室Ｒ４に滞在する監視員は、防護区画Ｐ１において火災が感知されたことを知ることができる。 1-2-2-1. Automatic Mode FIGS. 7 and 8 are sequence diagrams showing an example of a fire extinguishing operation for a protected area in which the operation mode is set to the automatic mode.
A fire broke out in a protected area whose operation mode is set to automatic mode (hereinafter referred to as "protected area P1" in the description of this operation), and the fire that occurred is a fire detector installed in the protected area P1. When detected by 2, the fire detector 2 outputs an operation signal to the fire receiver 10. The control unit 101 of the fire receiver 10 to which this operation signal is input (step Sb1) turns on the fire light 1021 of the fire receiver 10 and sounds the buzzer 103 (step Sb2). As a result, the observer staying in the monitoring room R4 can know that a fire has been detected in the protected area P1.
　また、制御部１０１は、防護区画Ｐ１に設置されているベル４を間欠鳴動させるために、防護区画Ｐ１に設置されているガス消火制御装置９に対して起動信号を出力する（ステップＳｂ３）。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、ベル４を間欠鳴動させる（ステップＳｂ４）。その結果、防護区画Ｐ１に滞在する者は、当該防護区画Ｐ１において火災が感知されたことを知ることができる。 Further, the control unit 101 outputs a start signal to the gas fire extinguishing control device 9 installed in the protected area P1 in order to intermittently ring the bell 4 installed in the protected area P1 (step Sb3). In response to this activation signal, the input / output control unit 94 of the gas fire extinguishing control device 9 intermittently rings the bell 4 (step Sb4). As a result, a person staying in the protected area P1 can know that a fire has been detected in the protected area P1.
　その後、防護区画Ｐ１において別の火災感知器２により火災が感知されると、当該別の火災感知器２は火災受信機１０に対して作動信号を出力する。この作動信号が入力された火災受信機１０の制御部１０１は（ステップＳｂ５）、２つの異なる火災感知器２から作動信号が入力されたことをもって、カウントダウン条件が充足されたと判定する。そして、防護区画Ｐ１内に消火ガスが放出されるまでのカウントダウン（例えば、６０秒）を開始し、当該カウントダウンをカウントダウン表示器１０２４に表示させる（ステップＳｂ６）。また、制御部１０１は、火災受信機１０の放出予告灯１０２２を点灯させる（ステップＳｂ７）。その結果、監視室Ｒ４に滞在する監視員は、防護区画Ｐ１内に消火ガスが放出されることと、放出されるまでの秒数を知ることができる。 After that, when a fire is detected by another fire detector 2 in the protected area P1, the other fire detector 2 outputs an operation signal to the fire receiver 10. The control unit 101 of the fire receiver 10 to which the operation signal is input determines (step Sb5) that the countdown condition is satisfied when the operation signal is input from two different fire detectors 2. Then, a countdown (for example, 60 seconds) until the fire extinguishing gas is released into the protected area P1 is started, and the countdown is displayed on the countdown indicator 1024 (step Sb6). Further, the control unit 101 turns on the release warning light 1022 of the fire receiver 10 (step Sb7). As a result, the observer staying in the monitoring room R4 can know that the fire extinguishing gas is released into the protection zone P1 and the number of seconds until the fire extinguishing gas is released.
　また、制御部１０１は、防護区画Ｐ１に設置されているガス消火制御装置９において放出予告灯９２１４を点滅させるとともに、カウントダウン表示器９２２に上記のカウントダウンを表示させるために、当該ガス消火制御装置９に対して起動信号を出力する（ステップＳｂ８）。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、表示部９２を制御する。表示部９２のうち、カウントダウン表示器９２２は、防護区画Ｐ１内に消火ガスが放出されるまでのカウントダウンを表示し（ステップＳｂ９）、放出予告灯９２１４は点滅する（ステップＳｂ１０）。その結果、このガス消火制御装置９の表示面を見た者は、防護区画Ｐ１内に消火ガスが放出されることと、放出されるまでの秒数を知ることができる。 Further, the control unit 101 blinks the release warning light 9214 in the gas fire extinguishing control device 9 installed in the protection zone P1 and displays the countdown on the countdown indicator 922, so that the gas fire extinguishing control device 9 is displayed. A start signal is output to (step Sb8). In response to this start signal, the input / output control unit 94 of the gas fire extinguishing control device 9 controls the display unit 92. Among the display units 92, the countdown display 922 displays the countdown until the fire extinguishing gas is released into the protection zone P1 (step Sb9), and the release warning light 9214 blinks (step Sb10). As a result, a person who sees the display surface of the gas fire extinguishing control device 9 can know that the fire extinguishing gas is released into the protection zone P1 and the number of seconds until the fire extinguishing gas is released.
　なお、カウントダウン表示器９２２に表示される残り時間は、火災受信機１０のカウントダウン表示器１０２４に表示される残り時間よりも早めにしてもよい。これにより、カウントダウン表示器９２２に表示されるカウントダウンが終了する前に緊急停止スイッチ７を操作したにもかかわらず、噴射ヘッド３から消火ガスが放出されてしまうという事態がより確実に防止される。 The remaining time displayed on the countdown display 922 may be earlier than the remaining time displayed on the countdown display 1024 of the fire receiver 10. As a result, the situation in which the fire extinguishing gas is discharged from the injection head 3 is more reliably prevented even though the emergency stop switch 7 is operated before the countdown displayed on the countdown indicator 922 is completed.
　また、火災受信機１０の制御部１０１は、防護区画Ｐ１に設置されているベル４を、より短い周期で間欠鳴動させるために、防護区画Ｐ１に設置されているガス消火制御装置９に対して起動信号を出力する（ステップＳｂ１１）。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、ベル４をより短い周期で間欠鳴動させる（ステップＳｂ１２）。その結果、防護区画Ｐ１に滞在する者は、防護区画Ｐ１内に消火ガスが放出されることを知ることができる。 Further, the control unit 101 of the fire receiver 10 with respect to the gas fire extinguishing control device 9 installed in the protection zone P1 in order to make the bell 4 installed in the protection zone P1 intermittently ring in a shorter cycle. The start signal is output (step Sb11). In response to this activation signal, the input / output control unit 94 of the gas fire extinguishing control device 9 intermittently rings the bell 4 at a shorter cycle (step Sb12). As a result, the person staying in the protected area P1 can know that the fire extinguishing gas is released into the protected area P1.
　その後、火災受信機１０の制御部１０１によるカウントダウンが終了すると（ステップＳｂ１３）、制御部１０１はガス放出条件が充足されたと判定する。そして、防護区画Ｐ１内に消火ガスを放出するために、当該防護区画Ｐ１のために設置されている起動用ガス容器１３の容器弁ソレノイドを制御する中継器１４に対して起動信号を出力する（ステップＳｂ１４）。この起動信号が中継器１４に入力されると、中継器１４は容器弁ソレノイドを作動させ、当該起動用ガス容器１３から起動用ガスを放出させる。そして、その起動用ガスのガス圧により、消火ガス貯蔵容器１１の容器弁と、防護区画Ｐ１のために設置されている選択弁１２を開放する。その結果、消火ガス貯蔵容器１１に貯蔵された消火ガスは、当該選択弁１２により分枝される配管を通って、防護区画Ｐ１に設置されている噴射ヘッド３から放出される。 After that, when the countdown by the control unit 101 of the fire receiver 10 is completed (step Sb13), the control unit 101 determines that the gas release condition is satisfied. Then, in order to release the fire extinguishing gas into the protected compartment P1, a start signal is output to the repeater 14 that controls the container valve solenoid of the starting gas container 13 installed for the protected compartment P1 ( Step Sb14). When this start signal is input to the repeater 14, the repeater 14 operates the container valve solenoid to release the start gas from the start gas container 13. Then, the container valve of the fire extinguishing gas storage container 11 and the selection valve 12 installed for the protection section P1 are opened by the gas pressure of the starting gas. As a result, the fire extinguishing gas stored in the fire extinguishing gas storage container 11 is discharged from the injection head 3 installed in the protection section P1 through the pipe branched by the selection valve 12.
　選択弁１２が開放されると、図示せぬ圧力スイッチが作動して、火災受信機１０に対して作動信号を出力する。この作動信号が入力された火災受信機１０の制御部１０１は（ステップＳｂ１５）、火災受信機１０の放出予告灯９２１４を消灯し、代わりに放出灯１０２３を点灯させる（ステップＳｂ１６）。その結果、監視室Ｒ４に滞在する監視員は、防護区画Ｐ１内に消火ガスが放出されていることを知ることができる。 When the selection valve 12 is opened, a pressure switch (not shown) operates to output an operation signal to the fire receiver 10. The control unit 101 of the fire receiver 10 to which this operation signal is input turns off the emission warning light 9214 of the fire receiver 10 (step Sb15), and turns on the release light 1023 instead (step Sb16). As a result, the observer staying in the monitoring room R4 can know that the fire extinguishing gas is released into the protected area P1.
　また、制御部１０１は、防護区画Ｐ１に設置されているガス消火制御装置９において放出灯９２１５を点灯させるために、当該ガス消火制御装置９に対して起動信号を出力する（ステップＳｂ１７）。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、表示部９２を制御する。表示部９２のうち、放出予告灯９２１４は消灯し、代わりに放出灯９２１５が点灯する（ステップＳｂ１８）。その結果、このガス消火制御装置９の表示面を見た者は、防護区画Ｐ１内に消火ガスが放出されていることを知ることができる。 Further, the control unit 101 outputs a start signal to the gas fire extinguishing control device 9 in order to turn on the emission lamp 9215 in the gas fire extinguishing control device 9 installed in the protection zone P1 (step Sb17). In response to this start signal, the input / output control unit 94 of the gas fire extinguishing control device 9 controls the display unit 92. Of the display unit 92, the emission foresight light 9214 is turned off, and the emission light 9215 is turned on instead (step Sb18). As a result, a person who sees the display surface of the gas fire extinguishing control device 9 can know that the fire extinguishing gas is released into the protection zone P1.
　また、火災受信機１０の制御部１０１は、防護区画Ｐ１に設置されているベル４を連続鳴動させるために、防護区画Ｐ１に設置されているガス消火制御装置９に対して起動信号を出力する（ステップＳｂ１９）。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、ベル４を連続鳴動させる（ステップＳｂ２０）。その結果、防護区画Ｐ１に滞在する者は、防護区画Ｐ１内に消火ガスが放出されていることを知ることができる。 Further, the control unit 101 of the fire receiver 10 outputs a start signal to the gas fire extinguishing control device 9 installed in the protected area P1 in order to continuously ring the bell 4 installed in the protected area P1. (Step Sb19). In response to this activation signal, the input / output control unit 94 of the gas fire extinguishing control device 9 continuously rings the bell 4 (step Sb20). As a result, the person staying in the protected area P1 can know that the fire extinguishing gas is released into the protected area P1.
　また、火災受信機１０の制御部１０１は、防護区画Ｐ１に設置されているストロボ５を発光させるために、防護区画Ｐ１に設置されているガス消火制御装置９に対して起動信号を出力する（ステップＳｂ２１）。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、ストロボ５を発光させる（ステップＳｂ２２）。その結果、防護区画Ｐ１に滞在する者は、防護区画Ｐ１内に消火ガスが放出されていることを視覚的に知ることができる。 Further, the control unit 101 of the fire receiver 10 outputs a start signal to the gas fire extinguishing control device 9 installed in the protected area P1 in order to make the strobe 5 installed in the protected area P1 emit light ( Step Sb21). In response to this activation signal, the input / output control unit 94 of the gas fire extinguishing control device 9 causes the strobe 5 to emit light (step Sb22). As a result, the person staying in the protected area P1 can visually know that the fire extinguishing gas is released into the protected area P1.
　また、火災受信機１０の制御部１０１は、防護区画Ｐ１に設置されている放出表示灯８を点灯させるために、防護区画Ｐ１に設置されているガス消火制御装置９に対して起動信号を出力する（ステップＳｂ２３）。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、放出表示灯８を点灯させる（ステップＳｂ２４）。その結果、防護区画Ｐ１の出入口付近にいる者は、防護区画Ｐ１内に消火ガスが放出されていることを知ることができる。
　以上が、動作モードが自動モードに設定されている防護区画に対する消火動作についての説明である。 Further, the control unit 101 of the fire receiver 10 outputs a start signal to the gas fire extinguishing control device 9 installed in the protected area P1 in order to light the emission indicator lamp 8 installed in the protected area P1. (Step Sb23). In response to this start signal, the input / output control unit 94 of the gas fire extinguishing control device 9 turns on the emission indicator lamp 8 (step Sb24). As a result, a person near the entrance / exit of the protected area P1 can know that the fire extinguishing gas is released into the protected area P1.
The above is the description of the fire extinguishing operation for the protected area where the operation mode is set to the automatic mode.
　なお、上記の消火動作において、防護区画Ｐ１に滞在する者が火災に気づき、当該防護区画Ｐ１に設置されている手動放出スイッチ６を操作した場合には、当該手動放出スイッチ６は起動信号を出力する。この起動信号は、防護区画Ｐ１に設置されているガス消火制御装置９の入出力制御部９４により中継されて、火災受信機１０に入力される。この起動信号が入力された火災受信機１０の制御部１０１は、別の火災感知器２からの作動信号の出力を待たずに、上記のステップＳｂ６以降を実行する。加えて、防護区画Ｐ１に設置されているガス消火制御装置９において手動放出灯９２１６を点灯させるために、当該ガス消火制御装置９に対して起動信号を出力する。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、表示部９２の手動放出灯９２１６を点灯させる。 In the above fire extinguishing operation, when a person staying in the protected area P1 notices the fire and operates the manual release switch 6 installed in the protected area P1, the manual release switch 6 outputs a start signal. To do. This start signal is relayed by the input / output control unit 94 of the gas fire extinguishing control device 9 installed in the protection zone P1 and input to the fire receiver 10. The control unit 101 of the fire receiver 10 to which the start signal is input executes the above steps Sb6 and subsequent steps without waiting for the output of the operation signal from another fire detector 2. In addition, in order to turn on the manual emission lamp 9216 in the gas fire extinguishing control device 9 installed in the protection zone P1, a start signal is output to the gas fire extinguishing control device 9. In response to this activation signal, the input / output control unit 94 of the gas fire extinguishing control device 9 turns on the manual emission lamp 9216 of the display unit 92.
　また、上記の消火動作において、カウントダウンの開始後に、防護区画Ｐ１に滞在する者が非火災を確認し、防護区画Ｐ１に設置されている緊急停止スイッチ７を操作すると、当該緊急停止スイッチ７は停止信号を出力する。この停止信号は、防護区画Ｐ１に設置されているガス消火制御装置９の入出力制御部９４により中継されて、火災受信機１０に入力される。この停止信号が入力された火災受信機１０の制御部１０１は、カウントダウンを停止する。加えて、防護区画Ｐ１に設置されているガス消火制御装置９においてカウントダウン表示器９２２に表示されているカウントダウンを停止させるとともに、緊急停止灯９２１７を点灯させるために、当該ガス消火制御装置９に対して起動信号を出力する。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、表示部９２を制御する。表示部９２のうち、カウントダウン表示器９２２はカウントダウンを停止し、緊急停止灯９２１７は点灯する。 Further, in the above fire extinguishing operation, after the start of the countdown, when a person staying in the protected area P1 confirms non-fire and operates the emergency stop switch 7 installed in the protected area P1, the emergency stop switch 7 is stopped.

　以上が、動作モードが手動モードに設定されている防護区画に対する消火動作についての説明である。 Further, the control unit 101 of the fire receiver 10 outputs a start signal to the gas fire extinguishing control device 9 installed in the protected area P2 in order to light the emission indicator lamp 8 installed in the protected area P2. (Step Sc21). In response to this start signal, the input / output control unit 94 of the gas fire extinguishing control device 9 turns on the emission indicator lamp 8 (step Sc22).
The above is the description of the fire extinguishing operation for the protected area where the operation mode is set to the manual mode.
　以上説明した実施形態に係る火災受信機１０は、上記の通り、緊急停止スイッチ７から出力される停止信号を、火災感知器２から出力される作動信号よりも優先的に受信する。また、火災受信機１０は、上記の通り、この停止信号の受信に連動して実行されるべきカウントダウンを停止する処理を優先的に実行する。そのため、緊急停止スイッチ７が操作されてから火災受信機１０がカウントダウンを停止するまでに要する遅延時間が短縮される。その結果、ガス消火制御装置９に表示されるカウントダウンを終了する前に緊急停止スイッチ７を操作したにもかかわらず、噴射ヘッド３から消火ガスが放出されてしまうという事態が防止される。 As described above, the fire receiver 10 according to the embodiment described above receives the stop signal output from the emergency stop switch 7 with priority over the operation signal output from the fire detector 2. Further, as described above, the fire receiver 10 preferentially executes the process of stopping the countdown that should be executed in conjunction with the reception of the stop signal. Therefore, the delay time required from the operation of the emergency stop switch 7 until the fire receiver 10 stops the countdown is shortened. As a result, it is possible to prevent a situation in which the fire extinguishing gas is discharged from the injection head 3 even though the emergency stop switch 7 is operated before the countdown displayed on the gas fire extinguishing control device 9 is completed.
　加えて、以上説明した実施形態に係るガス消火制御装置９は、同じ防護区画に設置された端末装置と火災受信機１０との間で信号を中継するための入出力制御部９４を備える。そして、各端末装置はこのガス消火制御装置９と信号線を介して接続され、このガス消火制御装置９を介して火災受信機１０と信号の送受信を行う。そのため、各端末装置を火災受信機１０と直接接続する場合と比較して、配線作業が容易になる。 In addition, the gas fire extinguishing control device 9 according to the embodiment described above includes an input / output control unit 94 for relaying a signal between the terminal device installed in the same protected area and the fire receiver 10. Then, each terminal device is connected to the gas fire extinguishing control device 9 via a signal line, and transmits / receives a signal to and from the fire receiver 10 via the gas fire extinguishing control device 9. Therefore, the wiring work becomes easier as compared with the case where each terminal device is directly connected to the fire receiver 10.
　上記の特許文献１に記載のガス系消火設備では、防護区画の各々に設置される操作箱、放出表示灯及びスピーカは、それぞれ別の信号線で制御盤と接続されている。そのため、各防護区画につき少なくも３個の中継器を用意し、これらの中継器の各々と制御盤を信号線で接続する必要があり、配線作業が複雑になっていた。これに対して、上記の実施形態は、ガス系消火設備の端末装置と火災受信機の間の配線作業を容易にする。 In the gas-based fire extinguishing system described in Patent Document 1 above, the operation box, the emission indicator, and the speaker installed in each of the protected areas are connected to the control panel by separate signal lines. Therefore, it is necessary to prepare at least three repeaters for each protected area and connect each of these repeaters to the control panel with a signal line, which complicates the wiring work. On the other hand, the above embodiment facilitates the wiring work between the terminal device of the gas-based fire extinguishing system and the fire receiver.
　なお、本実施形態に係るガス消火制御装置９は、以下のようにも表現され得る。
　防護区画に設置された端末装置と、火災受信機との間で信号を中継するための中継装置であって、
　前記端末装置は、

２．変形例
　上記の実施形態は以下のように変形してもよい。以下に記載する変形例は互いに組み合わせてもよい。 2. Modification Example The above embodiment may be modified as follows. The modifications described below may be combined with each other.
２－１．変形例１
　防護区画に設置する音響装置として、ベル４に代えてホーンを採用してもよい。 2-1. Modification 1
A horn may be used instead of the bell 4 as the sound device installed in the protected area.
２－２．変形例２
　上記の建物Ｂでは、１つの防護区画につき、１台のガス消火制御装置９が設置されている。しかし、出入口を２カ所有する防護区画については、２台のガス消火制御装置９を設置してもよい。その場合、火災受信機１０の防護区画設定テーブルＴＢＬ２には、その防護区画のＩＤに対応付けて、２台のガス消火制御装置９のアドレスが格納されることになる。また、２台のガス消火制御装置９のアドレスの各々について動作モードが対応付けられることになる。すなわち、その防護区画のＩＤに２つの動作モードが対応付けられることになる。これら２つの動作モードが共通する場合には、その防護区画の動作モードを一意に判定することができる。しかし、これら２つの動作モードが相違する場合には、その防護区画が自動モードであるのか手動モードであるのかを判定することができない。その結果、火災受信機１０による消火動作が停止してしまう。そこで、そのような事態を回避するために、火災受信機１０の動作モード判定部１０６は、防護区画に対応付けられている２つの動作モードが相違する場合に、一律に手動モードと判定するようにしてもよい。 2-2. Modification 2
In the above building B, one gas fire extinguishing control device 9 is installed for each protected area. However, two gas fire extinguishing control devices 9 may be installed in the protected area having two entrances and exits. In that case, the addresses of the two gas fire extinguishing control devices 9 are stored in the protection zone setting table TBL2 of the fire receiver 10 in association with the ID of the protection zone. Further, the operation mode is associated with each of the addresses of the two gas fire extinguishing control devices 9. That is, two operation modes are associated with the ID of the protected area. When these two operation modes are common, the operation mode of the protected area can be uniquely determined. However, when these two operation modes are different, it cannot be determined whether the protected area is in the automatic mode or the manual mode. As a result, the fire extinguishing operation by the fire receiver 10 is stopped. Therefore, in order to avoid such a situation, the operation mode determination unit 106 of the fire receiver 10 uniformly determines the manual mode when the two operation modes associated with the protection zone are different. It may be.
２－３．変形例３
　上記の手動モード時に実行される消火動作において、カウントダウンの開始後に、防護区画Ｐ２に滞在する者が非火災を確認し、防護区画Ｐ２に設置されている緊急停止スイッチ７を操作した場合に、当該緊急停止スイッチ７は停止信号を出力してもよい。この停止信号は、防護区画Ｐ２に設置されているガス消火制御装置９の入出力制御部９４により中継されて、火災受信機１０に入力される。この停止信号が入力された火災受信機１０の制御部１０１は、カウントダウンを停止する。加えて、防護区画Ｐ２に設置されているガス消火制御装置９においてカウントダウン表示器９２２に表示されているカウントダウンを停止させるとともに、緊急停止灯９２１７を点灯させるために、当該ガス消火制御装置９に対して起動信号を出力する。この起動信号を受けて、ガス消火制御装置９の入出力制御部９４は、表示部９２を制御する。表示部９２のうち、カウントダウン表示器９２２はカウントダウンを停止し、緊急停止灯９２１７は点灯する。 2-3. Modification 3

The emergency stop switch 7 may output a stop signal. This stop signal is relayed by the input / output control unit 94 of the gas fire extinguishing control device 9 installed in the protection zone P2, and is input to the fire receiver 10. The control unit 101 of the fire receiver 10 to which the stop signal is input stops the countdown. In addition, in order to stop the countdown displayed on the countdown indicator 922 in the gas fire extinguishing control device 9 installed in the protection zone P2 and turn on the emergency stop light 9217, the gas fire extinguishing control device 9 is used. And outputs a start signal. In response to this start signal, the input / output control unit 94 of the gas fire extinguishing control device 9 controls the display unit 92. Among the display units 92, the countdown display 922 stops the countdown, and the emergency stop light 9217 lights up.
２－４．変形例４
　火災感知器２に代えてアナログ式火災感知器を使用してもよい。その場合、火災感知器２に代えて火災受信機１０が火災の発生を判定する。具体的には、火災受信機１０は、アナログ式火災感知器から定期的に感知器信号としてアナログ値（例えば、煙濃度を示す値）を受信し、受信したアナログ値を所定の閾値と比較し、受信したアナログ値が所定の閾値を超えたときに火災が発生したと判定する。 2-4. Modification 4
An analog fire detector may be used instead of the fire detector 2. In that case, the fire receiver 10 determines the occurrence of a fire instead of the fire detector 2. Specifically, the fire receiver 10 periodically receives an analog value (for example, a value indicating smoke concentration) as a detector signal from the analog fire detector, and compares the received analog value with a predetermined threshold value. , It is determined that a fire has occurred when the received analog value exceeds a predetermined threshold value.
