本発明はＰ型火災受信機を備えた火災報知設備に関するものである。 The present invention relates to a fire alarm facility equipped with a P-type fire receiver.
従来、防護領域に設置された火災感知器と防災センター等に設置されたＰ型火災受信機を備えた火災報知設備がある。この火災報知設備は、火災感知器が火災を検出または、発信機が利用者によって押下されることで内部接点が閉じられ、火報回線が略短絡し、火報回線にかかる電圧を低下させる。 Conventionally, there is a fire alarm facility equipped with a fire detector installed in a protection area and a P-type fire receiver installed in a disaster prevention center or the like. In this fire alarm system, when the fire detector detects a fire or when the transmitter is pressed by the user, the internal contact is closed, the fire alarm line is substantially short-circuited, and the voltage applied to the fire alarm line is reduced.
Ｐ型火災受信機は、火報回線にかかる電圧の低下を検出すると火災警報を行うと共に、対応する防護領域の防排煙装置や防火戸などの被制御装置を動作させる連動制御信号を出力する。（特許文献１参照）。 The P-type fire receiver issues a fire alarm when it detects a drop in voltage applied to the fire alarm line, and outputs an interlock control signal for operating a controlled device such as a smoke prevention device or a fire door in the corresponding protection area. . (See Patent Document 1).
このような火災報知設備に用いられるＰ型火災受信機は、設置される建物に応じて、火災感知器や発信機が接続される火報回線、及び、防排煙装置、エレベータ制御盤や、避難誘導装置が接続される制御回線の回線数をあらかじめ用意した状態で出荷される。回線数に合わせて火災受信回路、制御装置回路（基板）の必要数が用意されるので、その数に対応した筐体の火災受信機を選定し、現場に設置する。 P-type fire receivers used for such fire alarm equipment are fire alarm lines connected to fire detectors and transmitters, smoke control devices, elevator control panels, Shipped with the number of control lines connected to the evacuation guidance device prepared in advance. The necessary number of fire receiving circuits and control device circuits (boards) is prepared according to the number of lines. Select a fire receiver with a housing corresponding to the number and install it on site.
しかし、現場によってはレイアウト変更等の設計変更に伴い、特に制御回線が足りない場合が生じることがあり、新たに回線数を増加させる必要がある。 However, depending on the site, there may be a case where the control lines are not enough due to the design change such as the layout change, and it is necessary to newly increase the number of lines.
Ｐ型火災受信機の筐体によっては、新たに制御回線を増設するための基板を設置するスペースが無い場合があり、制御回線の回線数を容易に増加できるものが望まれていた。 Depending on the housing of the P-type fire receiver, there may be no space for installing a board for newly adding a control line, and it has been desired to easily increase the number of control lines.
また、Ｐ型火災受信機の場合、回線単位で機器が接続されるため、単純に回線数を増加させると、受信機から建物内へ敷設される配線数が膨大な量となるという問題があった。 In the case of the P-type fire receiver, since devices are connected in units of lines, simply increasing the number of lines has a problem that the number of wires laid from the receiver to the building becomes enormous. It was.

The present invention relates to a plurality of fire detectors connected to a fire alarm line, a plurality of controlled devices connected to a control line, and a fire receiving circuit for receiving a fire signal from the fire detector via the fire alarm line. And a fire receiver having a control device circuit for controlling the controlled device via the control line, and a fire receiver circuit and a control unit for monitoring and controlling the control device circuit. The expansion control device circuit connected to the expansion controlled device via the internal circuit is provided inside.

The present invention also provides a plurality of fire detectors connected to the fire alarm line, a plurality of controlled devices connected to the control line, and a fire receiver that receives a fire signal from the fire detector via the fire alarm line. Expansion control in a fire alarm facility comprising a circuit, a control device circuit for controlling a controlled device via a control line, and a fire receiver having a fire receiving circuit and a control unit for monitoring and controlling the control device circuit An expansion control device circuit connected to the expansion controlled device via the line is provided inside, and includes a plurality of expansion boxes formed separately from the fire receiver, and a control device circuit provided in the fire receiver, The extension control device circuit provided in the extension box is connected via a signal line, and the control unit monitors and controls the extension control device circuit.

Further, since the P-type fire receiver and the extension box can be connected with a small number of signal lines, an effect of reducing the number of wires of the fire alarm equipment using the P-type fire receiver can be obtained.
In addition, since a plurality of extension control device circuits can be connected to each other with a pair of signal lines, even if it is desired to add extension controlled devices together at a remote location, wiring of fire alarm equipment using a P-type fire receiver The effect that the number can be reduced is obtained.
［実施形態１］
以下、本発明の火災報知設備１００の実施形態１を、図１及び図２を用いて説明する。
なお、各図において、各線Ｌ１、Ｌ２、Ｌ３は通常１対の配線が用いられるが、便宜上１本の線として表現したものである。
[Embodiment 1]
Hereinafter, Embodiment 1 of the fire alarm system 100 of the present invention will be described with reference to FIGS. 1 and 2.
In each figure, each of the lines L1, L2, and L3 is usually a pair of wires, but is represented as a single line for convenience.
１は回線単位で火災を監視するＰ型火災受信機１である。Ｐ型火災受信機１は、火報回線Ｌ１を介して火災感知器２が接続され、制御回線Ｌ２を介して被制御装置３が接続されている。火報回線Ｌ１は、火災受信回路４を介して火災受信機１と接続され、建物内の各防護領域へ向けて敷設されている。火報回線Ｌ１には、各防護領域に設けられ、火災を検出すると内部接点を閉じる火災感知器２や、利用者が押下すると内部接点を閉じる発信機５が接続されている。火災受信回路４は、火報回線Ｌ１に接続された火災感知器２や発信機５が内部接点を閉じると、回線が略短絡して電圧低下することによりその電圧低下を検出し、後述する制御部１２に火災信号を出力する。 Reference numeral 1 denotes a P-type fire receiver 1 that monitors a fire on a line-by-line basis. The P-type fire receiver 1 is connected to a fire detector 2 via a fire report line L1 and to a controlled device 3 via a control line L2. The fire alarm line L1 is connected to the fire receiver 1 via the fire receiving circuit 4, and is laid toward each protection area in the building. The fire alarm line L1 is connected to a fire sensor 2 that is provided in each protection area and closes an internal contact when a fire is detected, and a transmitter 5 that closes the internal contact when a user presses it. When the fire detector 2 or the transmitter 5 connected to the fire alarm line L1 closes the internal contact, the fire receiving circuit 4 detects the voltage drop due to a voltage drop caused by a short circuit of the line. A fire signal is output to the unit 12.
制御回線Ｌ２は、制御装置回路６を介して火災受信機１と接続され、火報回線Ｌ１と同様に各防護領域へ向けて敷設されている。制御回線Ｌ２には、各防護領域に設けられた火災感知器２や発信機５に対応する被制御装置３が接続されている。被制御装置３は、火災受信機１から出力される制御信号により制御装置回路６に設けられた移報接点（図示せず）がオンになると電源接続されて動作する装置であって、例えば、防排煙装置、防火戸、エレベータの制御を行うＥＶ盤や避難誘導を行う非常警報装置がある。 The control line L2 is connected to the fire receiver 1 via the control device circuit 6, and is laid toward each protection area in the same manner as the fire alarm line L1. A controlled device 3 corresponding to the fire detector 2 and the transmitter 5 provided in each protection area is connected to the control line L2. The controlled device 3 is a device that is connected to a power source and operates when a transfer contact (not shown) provided in the control device circuit 6 is turned on by a control signal output from the fire receiver 1, for example, There are smoke control devices, fire doors, EV panels that control elevators, and emergency warning devices that perform evacuation guidance.
制御装置回路６は、後述する増設制御装置回路８と同様の構成であり、制御部１２と接続される通信部１３と、被制御装置３を動作させる移報接点１５を複数備え、Ｐ型火災受信機１内に設けられている。 The control device circuit 6 has the same configuration as an expansion control device circuit 8 to be described later, and includes a communication unit 13 connected to the control unit 12 and a plurality of transfer contacts 15 for operating the controlled device 3, and a P-type fire. It is provided in the receiver 1.
Ｐ型火災受信機１は、火災や火災が発生した地区を表示する表示部９と、各種操作を行う操作部１０と、火災感知器２と被制御装置３の動作に関する対応関係を記憶する記憶部１１と、各信号の送受信等を制御する制御部１２とからなる。 The P-type fire receiver 1 stores a display unit 9 for displaying a fire or a district where a fire has occurred, an operation unit 10 for performing various operations, and a correspondence relationship regarding operations of the fire detector 2 and the controlled device 3. The unit 11 and a control unit 12 that controls transmission / reception of each signal.
表示部９はＰ型火災受信機１の盤面に設けられたＬＥＤ等の光源からなり、各防護領域に敷設された火報回線Ｌ１や制御回線Ｌ２に対応して設けられる。そして表示部９は、火報回線Ｌ１に接続された火災感知器２や、制御回線Ｌ２に接続された被制御装置３である防排煙装置が動作すると、制御部１２によって対応するＬＥＤ等が点灯制御されるものである。
操作部１０は、Ｐ型火災受信機１の盤面に設けられ、火災検出による火災警報の停止等を行う各種操作スイッチからなる。
The display unit 9 includes a light source such as an LED provided on the panel surface of the P-type fire receiver 1, and is provided corresponding to the fire alarm line L1 and the control line L2 laid in each protection area. When the fire detector 2 connected to the fire alarm line L1 or the smoke control device which is the controlled device 3 connected to the control line L2 operates, the display unit 9 displays a corresponding LED or the like by the control unit 12. The lighting is controlled.
The operation unit 10 is provided on the panel surface of the P-type fire receiver 1 and includes various operation switches for stopping a fire alarm by detecting a fire.
記憶部１１は、各防護領域に敷設された火報回線Ｌ１に対応して動作する制御回線Ｌ２の対応関係が記憶されている。この記憶部１１は、火災受信機１の出荷時や現場での設置時にデータベースツールを利用して、火報回線Ｌ１と制御回線Ｌ２の動作に関する対応関係を書き換え可能なものとなっている。 The storage unit 11 stores a correspondence relationship of the control line L2 that operates corresponding to the fire alarm line L1 laid in each protection area. The storage unit 11 can rewrite the correspondence relationship between the operation of the fire alarm line L1 and the control line L2 by using a database tool when the fire receiver 1 is shipped or installed on site.
制御部１２は、火災感知器２からの火災信号を受信して火災を断定すると、表示部９のＬＥＤを点灯させると共に、記憶部１１に記憶された対応関係に応じて対応する被制御装置３を動作させる連動制御信号を送信するものである。 When the control unit 12 receives the fire signal from the fire detector 2 and determines the fire, the control unit 12 turns on the LED of the display unit 9 and responds to the controlled device 3 corresponding to the correspondence stored in the storage unit 11. The interlock control signal which operates is transmitted.
７は、Ｐ型火災受信機と別体に形成された増設ボックス７で、内部に増設制御装置回路８が設けられている。増設制御装置回路８は、Ｐ型火災受信機１から送信される連動制御信号を受信する通信部１３と、受信した連動制御信号に対応する移報接点を動作させる動作部１４と、制御線Ｌ２に接続された被制御装置３を動作させる移報接点１５を備えている。増設制御装置回路８の通信部１３は、火災受信機１の制御部１２と信号線Ｌ３でそれぞれ接続されている。 Reference numeral 7 denotes an expansion box 7 formed separately from the P-type fire receiver, and an expansion control device circuit 8 is provided therein. The extension control device circuit 8 includes a communication unit 13 that receives the interlock control signal transmitted from the P-type fire receiver 1, an operation unit 14 that operates a transfer contact corresponding to the received interlock control signal, and a control line L2. And a transfer contact 15 for operating the controlled device 3 connected to. The communication unit 13 of the extension control device circuit 8 is connected to the control unit 12 of the fire receiver 1 through a signal line L3.
続いて、実施形態１における火災報知設備１００の設置時の説明をする。
Ｐ型火災受信機１は、設置される物件の規模に応じて、あらかじめ対応する回線数を設定して出荷される。その後、施工者によって火災感知器２や被制御装置３と共に設置される。このとき、レイアウト変更により設置する被制御装置３の数が増加した場合、Ｐ型火災受信機１とは別体に形成された増設ボックス７を新たに設置し、Ｐ型火災受信機の制御部１２と、増設ボックス７内に設けられた増設制御装置回路８の通信部１３を信号線Ｌ３によって接続する。そして、増設制御回路８から制御回線Ｌ２を増設し、増設被制御装置としての被制御装置３と制御回路Ｌ２を接続する。
Then, the description at the time of installation of the fire alarm equipment 100 in Embodiment 1 is given.
The P-type fire receiver 1 is shipped with a corresponding number of lines set in advance according to the scale of the property to be installed. Thereafter, it is installed together with the fire detector 2 and the controlled device 3 by the installer. At this time, when the number of controlled devices 3 to be installed increases due to the layout change, an additional box 7 formed separately from the P-type fire receiver 1 is newly installed, and the control unit of the P-type fire receiver 12 and the communication unit 13 of the extension control device circuit 8 provided in the extension box 7 are connected by a signal line L3. Then, the control line L2 is added from the extension control circuit 8, and the controlled device 3 as the added controlled device and the control circuit L2 are connected.
その後、出荷時のＰ型火災受信機１の記憶部１１には、火報回線Ｌ１と増設された制御回線Ｌ２との対応関係が入力されていないので、施工者はデータベースツール等を用いて記憶部１１に火報回線Ｌ１と制御回線Ｌ２との動作に関する対応関係を入力する。 Thereafter, since the correspondence between the fire alarm line L1 and the added control line L2 is not input to the storage unit 11 of the P-type fire receiver 1 at the time of shipment, the installer stores it using a database tool or the like. The correspondence relation regarding the operation of the fire alarm line L1 and the control line L2 is input to the unit 11.
より詳しく述べると、防護領域に設置された火災感知器２に対応する増設被制御装置を動作させるために、防護領域に敷設された火報回線Ｌ１と、増設被制御装置が接続された制御回線Ｌ２を動作させるための移報接点１５の動作関係を、記憶部１１に記憶させる。
このように、Ｐ型火災受信機１の設置現場において、被制御装置３が増えた場合でも、移報接点を容易に増設できるので、汎用性が向上する。
More specifically, in order to operate the additional controlled device corresponding to the fire detector 2 installed in the protection area, the fire alarm line L1 laid in the protection area and the control line to which the additional controlled apparatus is connected. The operation relationship of the transfer contact 15 for operating L2 is stored in the storage unit 11.
As described above, even when the number of controlled devices 3 increases in the installation site of the P-type fire receiver 1, the number of transfer contacts can be easily increased, so that versatility is improved.
次に、実施形態１における火災報知設備１００の火災時の動作を説明する。
防護領域に火災が発生すると、火災が発生した防護領域内に設置された火災感知器２が火災を検出して内部接点を閉じる。火災感知器２が内部接点を閉じると、火報回線Ｌ１が略短絡して電圧が低下する。この電圧低下を検出すると、火災受信回路４が制御部１２に火災信号を出力する。制御部１２は、火災受信回路４から火災信号を受信すると、火災を検出した回路と対応する表示部９を点灯制御する。更に制御部１２は、記憶部１１に記憶された火報回線Ｌ１と制御回線Ｌ２の対応関係から、対応する制御回線Ｌ２が接続された移報接点１５を動作させる連動制御信号を、信号線Ｌ３を介して、制御装置回路６及び増設制御回路８に送信する。その後、通信部１３がＰ型火災受信機１００から連動制御信号を受信すると、制御装置回路６及び増設制御回路８の動作部１４は、受信した連動制御信号の情報と自身の移報接点１５の情報を照らし合わせる。そして動作部１４は、受信した連動制御信号と対応する移報接点１５を有している場合、連動制御信号と対応する移報接点１５を動作させ、対応する移報接点１５を有していない場合、何もしない。このように、火災が発生した防護領域が、レイアウト変更によって新たに被制御装置３が設置された空間であった場合でも、火報回線Ｌ１と新たに増設された制御回線Ｌ２の対応関係が記憶部１１に記憶されているので、対応する移報接点１５を動作させる連動制御信号を送信して、確実に被制御装置３を動作させることができる。
Next, the operation | movement at the time of the fire of the fire alarm equipment 100 in Embodiment 1 is demonstrated.
When a fire occurs in the protection area, the fire detector 2 installed in the protection area where the fire has occurred detects the fire and closes the internal contact. When the fire detector 2 closes the internal contact, the fire alarm line L1 is substantially short-circuited and the voltage is lowered. When this voltage drop is detected, the fire receiving circuit 4 outputs a fire signal to the control unit 12. When receiving a fire signal from the fire receiving circuit 4, the control unit 12 controls lighting of the display unit 9 corresponding to the circuit that has detected the fire. Further, the control unit 12 sends an interlocking control signal for operating the transfer contact 15 connected to the corresponding control line L2 from the correspondence relationship between the fire alarm line L1 and the control line L2 stored in the storage unit 11 to the signal line L3. To the control device circuit 6 and the expansion control circuit 8. After that, when the communication unit 13 receives the interlock control signal from the P-type fire receiver 100, the operation unit 14 of the control device circuit 6 and the extension control circuit 8 and the information of the received interlock control signal and its own transfer contact 15 Collate information. When the operating unit 14 has the corresponding relay contact 15 corresponding to the received interlock control signal, the operating unit 14 operates the corresponding relay contact 15 corresponding to the interlock control signal and does not have the corresponding relay contact 15. If you do nothing. As described above, even when the protection area where the fire has occurred is a space where the controlled device 3 is newly installed by changing the layout, the correspondence relationship between the fire alarm line L1 and the newly added control line L2 is stored. Since it is stored in the unit 11, it is possible to reliably operate the controlled device 3 by transmitting an interlock control signal for operating the corresponding transfer contact 15.
［実施形態２］
次に、本発明の火災報知設備１０１の実施形態２を、図３、図４を用いて説明する。
火災報知設備１０１は、主に増設制御装置回路８の接続方法が実施の形態１の火災報知設備１００と異なり、他の構成は共通している。そこで、図３、図４において実施の形態１の火災報知設備１００と同一のものには同一の符号を付し、以下において実施の形態１と異なる部分のみを説明する。
[Embodiment 2]
Next, Embodiment 2 of the fire alarm facility 101 of the present invention will be described with reference to FIGS.
The fire alarm facility 101 differs from the fire alarm facility 100 of the first embodiment mainly in the connection method of the extension control device circuit 8, and the other configuration is common. Therefore, in FIG. 3 and FIG. 4, the same reference numerals are given to the same components as those of the fire alarm system 100 of the first embodiment, and only portions different from the first embodiment will be described below.
本実施形態２のＰ型火災受信機１０１は、制御装置回路６を増設制御装置回路８’と同じ回路とし、増設ボックス７を複数設け、さらに増設ボックス同士を信号線Ｌ３で接続した。 In the P-type fire receiver 101 of the second embodiment, the control device circuit 6 is the same circuit as the extension control device circuit 8 ', a plurality of extension boxes 7 are provided, and the extension boxes are connected to each other by a signal line L3.
増設制御装置回路８’は、Ｐ型火災受信機１０１の制御部１２または、増設制御装置回路８’同士を互いに接続可能な通信部１３’を設けた。そして制御部は、記憶部１１に記憶された火報回線Ｌ１と制御回線Ｌ２の対応関係から、対応する制御回線Ｌ２が接続された移報接点１５を動作させる連動制御信号を、信号線Ｌ３を介して、制御装置回路６及び増設制御回路８’に送信する。その後、通信部１３’がＰ型火災受信機１０１から連動制御信号を受信すると、動作部１４’は、受信した連動制御信号の情報と自身の移報接点１５の情報を照らし合わせる。そして動作部１４’は、受信した連動制御信号と対応する移報接点１５を有している場合、連動制御信号と対応する移報接点１５を動作させ、対応する移報接点１５を有していない場合、何もしない。このように、Ｐ型火災受信機１０１の制御部または、増設制御装置回路８’同士を互いに接続可能な通信部１３’を備え、互いに信号線Ｌ３で接続することで、火災受信機１０１から敷設される信号線Ｌ３が１対で済む。従って、防災センターから離れた位置に被制御装置３を増設する場合であっても、敷設する信号線Ｌ３の配線数を削減できる。 The expansion control device circuit 8 ′ is provided with a control unit 12 of the P-type fire receiver 101 or a communication unit 13 ′ that can connect the expansion control device circuits 8 ′ to each other. Then, the control unit, based on the correspondence relationship between the fire alarm line L1 and the control line L2 stored in the storage unit 11, sends an interlock control signal for operating the transfer contact 15 to which the corresponding control line L2 is connected, and the signal line L3. To the control device circuit 6 and the extension control circuit 8 ′. After that, when the communication unit 13 ′ receives the interlock control signal from the P-type fire receiver 101, the operation unit 14 ′ collates the received information on the interlock control signal with the information on its own transfer contact 15. When the operation unit 14 ′ has the transfer contact 15 corresponding to the received interlock control signal, the operation unit 14 ′ operates the transfer contact 15 corresponding to the interlock control signal and has the corresponding transfer contact 15. If not, do nothing. In this way, the control unit of the P-type fire receiver 101 or the communication unit 13 ′ that can connect the extension control device circuits 8 ′ to each other is provided, and is laid from the fire receiver 101 by being connected to each other by the signal line L3. One pair of signal lines L3 is sufficient. Therefore, even when the controlled device 3 is added at a position away from the disaster prevention center, the number of signal lines L3 to be laid can be reduced.
また、近年筐体の小型化が進んでおり、以前よりＰ型火災受信機が設置されていた物件をリニューアルする場合、建物内に敷設されている配線数は変わらず、Ｐ型火災受信機の筐体のみが小型化される場合がある。つまり、Ｐ型火災受信機に接続される配線数は変わらないため、新機種の筐体内への配線の引き込みが物理的に困難な場合が生じる。
この場合においても、本願発明の増設ボックスをＰ型火災受信機１の近くに設けることで、制御回線の一部を増設ボックスに引き込んで設置することができるという効果が得られる。
In addition, the housing has been downsized in recent years, and when renewing a property where a P-type fire receiver has been installed, the number of wires laid in the building remains the same. Only the housing may be downsized. That is, since the number of wires connected to the P-type fire receiver does not change, it may be physically difficult to draw the wires into the new model housing.
Even in this case, by providing the expansion box of the present invention near the P-type fire receiver 1, an effect that a part of the control line can be drawn into the expansion box and installed can be obtained.
また、実施形態２の増設ボックス７内に設けられた増設制御装置回路は、火災受信機１の制御部１２に接続されているが、例えば図３の破線で示す様に、火災受信機１内の増設制御装置回路８’と接続しても良い。 Further, the expansion control device circuit provided in the expansion box 7 of the second embodiment is connected to the control unit 12 of the fire receiver 1. For example, as shown by the broken line in FIG. It may be connected to the additional control device circuit 8 ′.
なお、実施例の火災報知設備ではＰ型火災受信機を用いて説明したが、Ｒ型火災受信機を備えた火災報知設備に適用してもよい。 In addition, although it demonstrated using the P-type fire receiver in the fire alarm facility of an Example, you may apply to the fire alarm facility provided with the R-type fire receiver.
