Description

本発明は、火災報知設備、特に火災受信機とＰ型配線接続された火災表示機の表示灯試験に関する。   The present invention relates to a fire alarm system, and more particularly to an indicator lamp test of a fire indicator connected to a fire receiver by P-type wiring.

火災受信機と火災表示機とをＰ型配線接続した火災報知設備が知られている（例えば、特許文献１参照）。   There is known a fire alarm facility in which a fire receiver and a fire indicator are connected by P-type wiring (for example, see Patent Document 1).

図２はＰ型配線接続した火災報知設備の従来例を示す図である。火災受信機ＲＥ２は、火災感知器が設けられた複数の感知器回線ＫＬ１〜ＫＬｎが接続され、複数の火災検出回路Ｋ１〜Ｋｎと、常時開の複数のスイッチＳＷ１〜ＳＷｎと、制御部１１０と、電源部１２０とを備えている。火災検出回路Ｋ１〜ＫｎとスイッチＳＷ１〜ＳＷｎとは、複数の感知器回線ＫＬ１〜ＫＬｎに対応して設けられ、スイッチＳＷ１〜ＳＷｎは、一端が共通の電源部１２０に接続され、他端が端子Ｉ１〜Ｉｎに接続されている。また、電源部１２０は端子Ｉ＋に接続され、また、端子Ｉ−はグランド接続されている。   FIG. 2 is a diagram showing a conventional example of fire alarm equipment connected to P-type wiring. The fire receiver RE2 is connected to a plurality of detector lines KL1 to KLn provided with fire detectors, a plurality of fire detection circuits K1 to Kn, a plurality of normally open switches SW1 to SWn, and a control unit 110. And a power supply unit 120. The fire detection circuits K1 to Kn and the switches SW1 to SWn are provided corresponding to the plurality of sensor lines KL1 to KLn. One end of each of the switches SW1 to SWn is connected to the common power supply unit 120 and the other end is a terminal. Connected to I1 to In. The power supply unit 120 is connected to the terminal I +, and the terminal I− is connected to the ground.

火災表示機ＤＰ２は、複数の感知器回線ＫＬ１〜ＫＬｎに対応して設けられた複数の表示灯Ｌ１〜Ｌｎと、表示灯試験スイッチＳＷＴと、逆流防止用のダイオードＤ１〜Ｄｎとを備えている。表示灯Ｌ１〜Ｌｎは、一端が端子ＩＩ１〜ＩＩｎに接続され、他端が端子ＩＩ−に接続されている。また、表示灯試験スイッチＳＷＴは、一端が端子ＩＩ＋に接続され、他端がダイオードＤ１〜Ｄｎを介して、表示灯Ｌ１〜Ｌｎに接続されている。   The fire indicator DP2 includes a plurality of indicator lamps L1 to Ln provided corresponding to the plurality of sensor lines KL1 to KLn, an indicator lamp test switch SWT, and backflow prevention diodes D1 to Dn. . One end of each of the indicator lamps L1 to Ln is connected to the terminals II1 to IIn, and the other end is connected to the terminal II-. The indicator lamp test switch SWT has one end connected to the terminal II + and the other end connected to the indicator lamps L1 to Ln via the diodes D1 to Dn.

そして、火災受信機ＲＥ２と火災表示機ＤＰ２とは、端子Ｉ１と端子ＩＩ１、端子Ｉ２と端子ＩＩ２、…、端子Ｉｎと端子ＩＩｎとの間を、感知器回線ＫＬ１〜ＫＬｎに対応して設けられた、火災表示制御線ｌ１〜ｌｎで接続されている。また、端子Ｉ＋と端子ＩＩ＋との間を表示灯試験線ｌ＋で接続され、端子Ｉ−と端子ＩＩ−との間をグランドｌ−線で接続されている。   The fire receiver RE2 and the fire indicator DP2 are provided between the terminals I1 and II1, the terminals I2 and II2,..., The terminals In and IIn corresponding to the sensor lines KL1 to KLn. The fire display control lines 11 to ln are connected. Further, the terminal I + and the terminal II + are connected by an indicator lamp test line l +, and the terminal I− and the terminal II− are connected by a ground l− line.

つまり、複数の感知器回線ＫＬ１〜ＫＬｎに対応した複数の火災検出回路Ｋ１〜ＫｎおよびスイッチＳＷ１〜ＳＷｎが火災受信機ＲＥ２に設けられ、複数の感知器回線ＫＬ１〜ＫＬｎに対応した複数の表示灯Ｌ１〜Ｌｎが火災表示機ＤＰ２に設けられ、対応するスイッチＳＷ１〜ＳＷｎと表示灯Ｌ１〜Ｌｎとが、複数の火災表示制御線ｌ１〜ｌｎで接続されており、火災受信機ＲＥ２と火災表示機ＤＰ２とは、火災表示制御線ｌ１〜ｌｎによって、Ｐ型配線接続されている。そして、制御部１１０は、火災検出部Ｋ１〜Ｋｎが火災を検出すると、対応するスイッチＳＷ１〜ＳＷｎをオンする。これにより、電源部１２０からの電源が、対応するスイッチＳＷ１〜ＳＷｎ、対応する火災表示制御線ｌ１〜ｌｎを介して、対応する表示灯Ｌ１〜Ｌｎに供給され、対応する表示灯Ｌ１〜Ｌｎを点灯させて、火災表示機ＤＰ２で感知器回線ＫＬ１〜ＫＬｎ毎の火災表示を行うことができる。   That is, a plurality of fire detection circuits K1 to Kn and switches SW1 to SWn corresponding to the plurality of sensor lines KL1 to KLn are provided in the fire receiver RE2, and a plurality of indicator lights corresponding to the plurality of sensor lines KL1 to KLn. L1 to Ln are provided in the fire indicator DP2, and the corresponding switches SW1 to SWn and indicator lights L1 to Ln are connected by a plurality of fire display control lines 11 to ln, and the fire receiver RE2 and the fire indicator DP2 is connected to P2 by fire display control lines 11 to ln. And if the fire detection part K1-Kn detects a fire, the control part 110 will turn ON corresponding switch SW1-SWn. Thereby, the power from the power supply unit 120 is supplied to the corresponding indicator lamps L1 to Ln via the corresponding switches SW1 to SWn and the corresponding fire display control lines 11 to ln, and the corresponding indicator lights L1 to Ln are supplied. It is possible to turn on the light and display the fire for each of the sensor lines KL1 to KLn with the fire indicator DP2.

また、表示灯点灯試験を行う場合は、火災表示機ＤＰ２上の表示灯試験スイッチＳＷＴをオンすることによって、電源部１２０からの電源が、表示灯試験線ｌ＋、スイッチＳＷＴ、ダイオードＤ１〜Ｄｎを介して、表示灯Ｌ１〜Ｌｎに供給されるので、表示灯Ｌ１〜Ｌｎの点灯消灯状態により、表示灯Ｌ１〜Ｌｎの故障（断線など）の有無や、表示灯試験線ｌ＋、グランド線ｌ−などの配線の断線の有無を確認することができる。
特開平１０−３２０６６５号公報。 In addition, when the indicator lamp lighting test is performed, the indicator lamp test switch SWT on the fire indicator DP2 is turned on so that the power source from the power supply unit 120 switches the indicator lamp test line l +, the switch SWT, and the diodes D1 to Dn. Therefore, depending on whether the indicator lamps L1 to Ln are turned on or off, the indicator lamps L1 to Ln have a failure (disconnection, etc.), the indicator lamp test line l +, and the ground line l−. It is possible to confirm whether or not the wiring is disconnected.
Japanese Patent Laid-Open No. 10-320665.

上記表示灯点灯試験は、表示灯Ｌ１〜Ｌｎの故障の有無や、表示灯試験線ｌ＋、グランド線ｌ−などの配線の断線の有無を確認することができるが、火災表示制御線ｌ１〜ｌｎの断線の有無を確認することができなかった。そのため、火災時に、必要な表示灯Ｌ１〜Ｌｎが点灯しないということが考えられ、好ましくない。   The above indicator lamp lighting test can confirm the presence or absence of failure of the indicator lamps L1 to Ln and the presence or absence of disconnection of the indicator lamp test line l +, ground line l−, etc., but the fire display control lines 11 to ln. The presence or absence of disconnection could not be confirmed. Therefore, it is conceivable that necessary indicator lights L1 to Ln are not turned on at the time of a fire, which is not preferable.

本発明は、表示灯点灯試験によって、火災表示制御線の断線の有無を確認することができる火災報知設備を提供することを目的とするものである。   An object of this invention is to provide the fire alarm equipment which can confirm the presence or absence of the disconnection of a fire display control line by an indicator lamp lighting test.

図１は、本発明の一実施例であるＰ型配線接続した火災報知設備を示す図である。なお、図２で説明したものと同一機能のものには同一符号および同一名称を付与してあるので説明を省略する。   FIG. 1 is a diagram showing a fire alarm facility with P-type wiring connection according to an embodiment of the present invention. In addition, since the same code | symbol and the same name are provided to the thing of the same function as what was demonstrated in FIG. 2, description is abbreviate | omitted.

火災報知設備は、火災感知器が設けられた複数の感知器回線ＫＬ１〜ＫＬｎと、火災受信機ＲＥ１と、火災表示機ＤＰ１と、火災受信機ＲＥ１と火災表示機ＤＰ１とを接続する、表示灯試験線ｌ＋、火災表示制御線ｌ１〜ｌｎ、グランド線ｌ−とを有する。   The fire alarm system has an indicator light for connecting a plurality of detector lines KL1 to KLn provided with a fire detector, a fire receiver RE1, a fire indicator DP1, and a fire receiver RE1 and a fire indicator DP1. It has a test line l +, fire display control lines 11 to ln, and a ground line l−.

火災受信機ＲＥ１は、複数の感知器回線ＫＬ１〜ＫＬｎが接続される複数の火災検出回路Ｋ１〜Ｋｎと、常時開の複数のスイッチＳＷ１〜ＳＷｎと、制御部１０と、電源部２０と、オン検出回路４０とを備えている。   The fire receiver RE1 includes a plurality of fire detection circuits K1 to Kn to which a plurality of sensor lines KL1 to KLn are connected, a plurality of normally open switches SW1 to SWn, a control unit 10, a power supply unit 20, And a detection circuit 40.

火災検出回路Ｋ１〜ＫｎとスイッチＳＷ１〜ＳＷｎとは、複数の感知器回線ＫＬ１〜ＫＬｎに対応して設けられ、スイッチＳＷ１〜ＳＷｎは、一端が共通の電源部２０に接続され、他端が端子Ｉ１〜Ｉｎに接続されている。また、電源部２０は、オン検出回路４０を介して、端子ＩＴＩに供給され、また、端子Ｉ−はグランド接続されている。   The fire detection circuits K1 to Kn and the switches SW1 to SWn are provided corresponding to the plurality of sensor lines KL1 to KLn. One end of each of the switches SW1 to SWn is connected to the common power supply unit 20 and the other end is a terminal. Connected to I1 to In. The power supply unit 20 is supplied to the terminal ITI via the ON detection circuit 40, and the terminal I- is grounded.

火災表示機ＤＰ１は、複数の感知器回線ＫＬ１〜ＫＬｎに対応して設けられた複数の表示灯Ｌ１〜Ｌｎと、表示灯試験スイッチＳＷＴとを備えている。表示灯Ｌ１〜Ｌｎは、一端が端子ＩＩ１〜ＩＩｎに接続され、他端が端子ＩＩ−に接続されている。また、表示灯試験スイッチＳＷＴは、一端が端子ＩＩＴＩに接続され、他端が端子ＩＩ−に接続されている。   The fire indicator DP1 includes a plurality of indicator lamps L1 to Ln provided corresponding to the plurality of sensor lines KL1 to KLn, and an indicator lamp test switch SWT. One end of each of the indicator lamps L1 to Ln is connected to the terminals II1 to IIn, and the other end is connected to the terminal II-. The indicator lamp test switch SWT has one end connected to the terminal IITI and the other end connected to the terminal II-.

そして、火災受信機ＲＥ１と火災表示機ＤＰ１とは、端子Ｉ１と端子ＩＩ１、端子Ｉ２と端子ＩＩ２、…、端子Ｉｎと端子ＩＩｎとの間を、感知器回線ＫＬ１〜ＫＬｎに対応して設けられた、火災表示制御線ｌ１〜ｌｎで接続されている。また、端子ＩＴＩと端子ＩＩＴＩとの間を表示灯試験線ｌ＋で接続され、端子Ｉ−と端子ＩＩ−との間をグランドｌ−線で接続されている。   The fire receiver RE1 and the fire indicator DP1 are provided between the terminal I1 and the terminal II1, the terminal I2 and the terminal II2,..., The terminal In and the terminal IIn corresponding to the sensor lines KL1 to KLn. The fire display control lines 11 to ln are connected. Further, the terminal ITI and the terminal IITI are connected by an indicator lamp test line l +, and the terminal I− and the terminal II− are connected by a ground l− line.

つまり、複数の感知器回線ＫＬ１〜ＫＬｎに対応した複数の火災検出回路Ｋ１〜ＫｎおよびスイッチＳＷ１〜ＳＷｎが火災受信機ＲＥ１に設けられ、複数の感知器回線ＫＬ１〜ＫＬｎに対応した複数の表示灯Ｌ１〜Ｌｎが火災表示機ＤＰ１に設けられ、対応するスイッチＳＷ１〜ＳＷｎと表示灯Ｌ１〜Ｌｎとが、複数の火災表示制御線ｌ１〜ｌｎで接続されており、火災受信機ＲＥ１と火災表示機ＤＰ１とは、火災表示制御線ｌ１〜ｌｎによって、Ｐ型配線接続されている。そして、制御部１０は、火災検出部Ｋ１〜Ｋｎが対応する感知器回線ＫＬ１〜ＫＬｎの火災を検出すると、対応するスイッチＳＷ１〜ＳＷｎを閉じる。これにより、電源部２０からの電源が、対応するスイッチＳＷ１〜ＳＷｎ、対応する火災表示制御線ｌ１〜ｌｎを介して、対応する表示灯Ｌ１〜Ｌｎに供給され、対応する表示灯Ｌ１〜Ｌｎを点灯させて、火災表示機ＤＰ１で感知器回線ＫＬ１〜ＫＬｎ毎の火災表示を行うことができる。   That is, a plurality of fire detection circuits K1 to Kn and switches SW1 to SWn corresponding to the plurality of sensor lines KL1 to KLn are provided in the fire receiver RE1, and a plurality of indicator lights corresponding to the plurality of sensor lines KL1 to KLn. L1 to Ln are provided in the fire indicator DP1, and the corresponding switches SW1 to SWn and indicator lights L1 to Ln are connected by a plurality of fire display control lines 11 to ln, and the fire receiver RE1 and the fire indicator DP1 is connected to P1 by fire display control lines 11 to ln. And the control part 10 will close corresponding switch SW1-SWn, if the fire detection part K1-Kn detects the fire of the sensor line KL1-KLn corresponding. Thereby, the power supply from the power supply unit 20 is supplied to the corresponding indicator lights L1 to Ln via the corresponding switches SW1 to SWn and the corresponding fire display control lines 11 to ln, and the corresponding indicator lights L1 to Ln are supplied. The fire indicator DP1 can be used to display the fire for each of the sensor lines KL1 to KLn.

つぎに、表示灯点灯試験を行い場合は、火災表示機ＤＰ１上の表示灯試験スイッチＳＷＴをオンする。ここで、表示灯試験線ｌ＋またはグランド線ｌ−が断線していれば、後述する表示灯Ｌ１〜Ｌｎの点灯試験時において、全ての表示灯Ｌ１〜Ｌｎが点灯しないので、表示灯試験線ｌ＋またはグランド線ｌ−が断線していることがわかる。   Next, when the indicator lamp lighting test is performed, the indicator lamp test switch SWT on the fire indicator DP1 is turned on. Here, if the indicator lamp test line l + or the ground line l− is disconnected, all the indicator lamps L1 to Ln are not lit during the lighting test of the indicator lamps L1 to Ln, which will be described later. It can also be seen that the ground line l− is disconnected.

一方、表示灯試験線ｌ＋またはグランド線ｌ−が断線していなければ、電源部２０からの電源が、オン検出回路４０、表示灯試験線ｌ＋、表示灯試験スイッチＳＷＴを介してグランド線ｌ−に供給される。つまり、火災表示機ＤＰ１に電源が供給されるので、これをオン検出回路４０が検出して、検出信号を制御部１０に出力する。   On the other hand, if the indicator light test line l + or the ground line l− is not broken, the power supply from the power supply unit 20 is connected to the ground line l− via the ON detection circuit 40, the indicator light test line l +, and the indicator light test switch SWT. To be supplied. That is, since power is supplied to the fire indicator DP1, the on-detection circuit 40 detects this and outputs a detection signal to the control unit 10.

制御部１０は、検出信号が入力すると、スイッチＳＷ１〜ＳＷｎを閉じる制御を順次行って、個々の表示灯Ｌ１〜Ｌｎの点灯試験を行う。つまり、最初にスイッチＳＷ１を閉じる。このとき、火災表示制御線ｌ１またはグランド線ｌ−が断線していなければ、または表示灯Ｌ１が故障（断線など）していなければ、電源部２０からの電源が、スイッチＳＷ１、火災表示制御線ｌ１を介して、表示灯Ｌ１に供給され、表示灯Ｌ１が点灯する。一方、火災表示制御線ｌ１またはグランド線ｌ−が断線していれば、または表示灯Ｌ１が故障していれば、電源部２０からの電源が、表示灯Ｌ１に供給されないので、表示灯Ｌ１が点灯しない。表示灯Ｌ１の点灯試験が終了すると、制御部１０は、スイッチＳＷ１を開き、次のスイッチＳＷ２を閉じ、表示灯Ｌ２の点灯試験を行う。これを最後の表示灯Ｌｎの点灯試験まで順次行うことにより、表示灯Ｌ１〜Ｌｎの点灯消灯状態により、表示灯Ｌ１〜Ｌｎの故障の有無のみならず、火災表示制御線ｌ１〜ｌｎの配線の断線の有無を確認することができる。つまり、表示灯Ｌ１〜Ｌｎの点灯によって、対応する表示灯Ｌ１〜Ｌｎが故障しておらず、かつ、対応する火災表示制御線ｌ１〜ｌｎの配線が断線していないことが判り、一方、表示灯Ｌ１〜Ｌｎの消灯によって、対応する表示灯Ｌ１〜Ｌｎが故障しているか、または、対応する火災表示制御線ｌ１〜ｌｎの配線が断線していることが判る。また、従来と同様に、表示灯試験線ｌ＋、グランド線ｌ−、などの配線の断線の有無を確認することができる。   When the detection signal is input, the control unit 10 sequentially performs control to close the switches SW1 to SWn, and performs lighting tests of the individual indicator lamps L1 to Ln. That is, the switch SW1 is first closed. At this time, if the fire display control line l1 or the ground line l- is not disconnected, or if the indicator lamp L1 is not broken (disconnected, etc.), the power from the power supply unit 20 is switched to the switch SW1, fire display control line. It is supplied to the indicator lamp L1 via l1, and the indicator lamp L1 is turned on. On the other hand, if the fire display control line l1 or the ground line l- is disconnected or if the indicator lamp L1 is broken, the power from the power supply unit 20 is not supplied to the indicator lamp L1, so the indicator lamp L1 is not light. When the lighting test of the indicator lamp L1 is completed, the control unit 10 opens the switch SW1, closes the next switch SW2, and performs the lighting test of the indicator lamp L2. By sequentially performing this until the last lighting test of the indicator lamp Ln, depending on whether the indicator lamps L1 to Ln are turned on or off, not only the presence or absence of a failure of the indicator lamps L1 to Ln but also the wiring of the fire display control lines 11 to ln. The presence or absence of disconnection can be confirmed. That is, it turns out that the corresponding display lamps L1 to Ln are not broken by the lighting of the display lamps L1 to Ln, and the wiring of the corresponding fire display control lines 11 to ln is not disconnected. By turning off the lights L1 to Ln, it can be seen that the corresponding indicator lights L1 to Ln have failed or the corresponding fire display control lines 11 to ln are disconnected. Further, as in the conventional case, it is possible to confirm the presence or absence of disconnection of the indicator lamp test line l +, the ground line l−, and the like.

以上、説明した通り、本実施例は、複数の感知器回線ＫＬ１〜ＫＬｎに対応して設けられた複数の火災検出回路Ｋ１〜Ｋｎと、複数の感知器回線ＫＬ１〜ＫＬｎに対応して設けられ、対応する火災検出回路Ｋ１〜Ｋｎが火災を検出したときに閉じられる複数のスイッチＳＷ１〜ＳＷｎと、を有する火災受信機ＲＥ１と；前記複数の感知器回線ＫＬ１〜ＫＬｎに対応して設けられた複数の表示灯Ｌ１〜Ｌｎを有する火災表示機ＤＰ１と；前記複数の感知器回線ＫＬ１〜ＫＬｎに対応して設けられ、対応する前記スイッチＳＷ１〜ＳＷｎと表示灯Ｌ１〜Ｌｎとを接続する複数の火災表示制御線ｌ１〜ｌｎと；を備えた火災報知設備において、表示灯試験スイッチＳＷＴを前記火災表示機ＤＰ１に設け、前記表示灯試験スイッチＳＷＴのオンを検出するオン検出回路４０を前記火災受信機ＲＥ１に設け、前記表示灯試験スイッチＳＷＴとオン検出回路４０とを表示灯試験線ｌ＋で接続し、前記オン検出回路４０が前記表示灯試験スイッチＳＷＴのオンを検出したときに、前記複数のスイッチＳＷ１〜ＳＷｎを閉じて、前記複数の表示灯Ｌ１〜Ｌｎの点灯試験を行う。つまり、表示灯Ｌ１〜Ｌｎの点灯試験時に、複数の火災表示制御線ｌ１〜ｌｎを介して複数の表示灯Ｌ１〜Ｌｎに電源を供給する構成としたので、複数の表示灯Ｌ１〜Ｌｎの点灯消灯状態により、複数の表示灯Ｌ１〜Ｌｎの故障（断線など）の有無のみでなく、複数の火災表示制御線ｌ１〜ｌｎの断線の有無を確認することができる。なお、従来と同様に、表示灯試験線ｌ＋、グランド線ｌ−の配線の断線の有無も確認することができるので、つまり、火災受信機ＲＥ１と火災表示機ＤＰ１との間の必要な配線の状態を確認することができる。   As described above, the present embodiment is provided corresponding to the plurality of fire detection circuits K1 to Kn provided corresponding to the plurality of sensor lines KL1 to KLn and the plurality of sensor lines KL1 to KLn. A fire receiver RE1 having a plurality of switches SW1 to SWn which are closed when the corresponding fire detection circuits K1 to Kn detect a fire; provided corresponding to the plurality of sensor lines KL1 to KLn A fire indicator DP1 having a plurality of indicator lamps L1 to Ln; a plurality of fire indicators DP1 provided corresponding to the plurality of sensor lines KL1 to KLn and connecting the corresponding switches SW1 to SWn and indicator lamps L1 to Ln. In a fire alarm system provided with fire display control lines 11 to ln, an indicator light test switch SWT is provided in the fire indicator DP1 to detect the on state of the indicator light test switch SWT. An ON detection circuit 40 is provided in the fire receiver RE1, the indicator light test switch SWT and the ON detection circuit 40 are connected by an indicator light test line l +, and the ON detector circuit 40 turns on the indicator light test switch SWT. Is detected, the plurality of switches SW1 to SWn are closed, and a lighting test of the plurality of indicator lights L1 to Ln is performed. That is, since the power is supplied to the plurality of display lamps L1 to Ln via the plurality of fire display control lines 11 to ln during the lighting test of the display lamps L1 to Ln, the lighting of the plurality of display lamps L1 to Ln is performed. From the light-off state, it is possible to confirm not only the presence / absence of failure (breakage or the like) of the plurality of indicator lights L1 to Ln but also the presence or absence of breakage of the plurality of fire display control lines 11 to ln.
