炎式火災感知器は、受光素子として例えば焦電形の赤外線検出素子（以下、焦 電素子という）を使用し、火災の炎から発する赤外線の特定波長領域の光を検出 して火災の発生を検知するものである。 A flame-type fire detector uses, for example, a pyroelectric infrared detection element (hereinafter referred to as a pyroelectric element) as a light receiving element, and detects light in a specific wavelength region of infrared rays emitted from a fire flame to detect the occurrence of a fire. It is something to detect.
【０００３】 図７は従来の炎式火災感知器の一例を示す断面図である。図において、１は筐 体で、底板３を有する円筒状の本体２と、係止爪５によって本体２に結合された カバー４とからなり、カバー４は本体２に結合される円筒部と傾斜部とによりほ ぼ富士山状に形成され、上面に設けた凹部６には透光窓７が設けられている。８ は凹部６内に嵌入され、接着剤９によりカバー４に接着固定されたサファイヤ等 からなる保護板である。FIG. 7 is a sectional view showing an example of a conventional flame-type fire detector. In the figure, reference numeral 1 denotes a casing, which is composed of a cylindrical main body 2 having a bottom plate 3 and a cover 4 coupled to the main body 2 by locking claws 5. The cover 4 is inclined with a cylindrical portion coupled to the main body 2. And a transparent window 7 is provided in the recess 6 provided on the upper surface. Reference numeral 8 denotes a protective plate which is fitted in the recess 6 and is made of sapphire or the like and fixed to the cover 4 by an adhesive 9.
【０００４】 １０は増幅回路、火災判別回路、スイッチング回路等（図示せず）を構成する 電気部品が実装されたプリント基板で、筐体１内に収容され、ネジ１１により底 板３に固定されている。１２は炎の赤外線を受光する受光素子で、例えばキャン 内に焦電素子が収容され、上面に設けた受光部はシリコン板で封止され、そのリ ード線１３がプリント基板１０にはんだ付けされている。なお、この時、受光素 子１２の受光部は保護板８に対向し、かつ近接して配設される。Reference numeral 10 denotes a printed circuit board on which electric parts constituting an amplification circuit, a fire determination circuit, a switching circuit and the like (not shown) are mounted, which is housed in the housing 1 and fixed to the bottom plate 3 by screws 11. ing. Reference numeral 12 is a light receiving element that receives infrared rays of flame, for example, a pyroelectric element is housed in a can, and the light receiving portion provided on the upper surface is sealed with a silicon plate, and its lead wire 13 is soldered to the printed circuit board 10. Has been done. At this time, the light-receiving portion of the light-receiving element 12 is arranged so as to face the protective plate 8 and be close thereto.
【０００５】 上記のように構成した炎式火災感知器は、受光素子１２が有する指向特性を生 かして炎からの赤外線を受光できる範囲、つまり、監視範囲を考え、未監視範囲 が発生しないように部屋の天井等に設置される。そして、監視範囲内で火災が発 生すると、受光素子１２の受光部は保護板８を透過した炎の赤外線を受光して特 定波長領域の光を検出し、この検出信号をリード線１３を介してプリント基板１ ０の回路等に送り、火災の発生を検知して例えば火災受信機に知らせる。この時 、火災発生場所がこの炎式火災感知器の監視範囲であることがはじめて確認され る。The flame-type fire detector configured as described above utilizes the directional characteristics of the light-receiving element 12 to receive an infrared ray from a flame, that is, considering a monitoring range, and an unmonitored range does not occur. Is installed on the ceiling of the room. Then, when a fire occurs within the monitoring range, the light receiving portion of the light receiving element 12 receives the infrared rays of the flame transmitted through the protective plate 8 to detect the light in the specific wavelength region, and the detection signal is sent to the lead wire 13. It is sent to the circuit or the like of the printed circuit board 10 through the circuit to detect the occurrence of fire and inform the fire receiver, for example. At this time, it is confirmed for the first time that the location of the fire is within the monitoring range of this flame fire detector.
【０００６】[0006]
一般に、火災感知器は、消防法により天井高さ４ｍ未満の耐火構造による火災 感知器１個の監視範囲が、例えば、 差動式感知器１種…９０ｍ2 、差動式感知器２種…７０ｍ2 定温式感知器特種…７０ｍ2 、定温式感知器特種…６０ｍ2 と決められており、これらの火災感知器の設置場所は決められた監視範囲に基づ いて未監視範囲が発生しないように設置されている。Generally, fire detectors have a fireproof structure with a ceiling height of less than 4 m, and the monitoring range of one fire detector is, for example, one type of differential type sensor ... 90 m 2 , two types of differential type sensor ... 70 m 2 constant temperature type sensor special type… 70 m 2 and constant temperature type sensor special type… 60 m 2 It is decided that the location of these fire detectors is based on the set monitoring range so that no unmonitored range occurs. It is installed in.
【０００７】 しかし、前述のような従来の炎式火災感知器は、指向特性による漏斗状の監視 範囲を持ち、この監視範囲を考慮して例えば部屋全体を監視できる場所に設置す るようにしている。However, the conventional flame-type fire detector as described above has a funnel-shaped monitoring range based on the directional characteristic, and in consideration of this monitoring range, for example, the entire room can be installed at a place where it can be monitored. There is.
【０００８】 ところで、このような炎式火災感知器においては、図８に示すように、天井Ｔ と床面Ｙが平行な部屋の場合は、天井Ｔのほぼ中央部に炎式火災感知器を設置し ている。しかしながら、図９に示すように、例えば体育館などの天井Ｔと床面Ｙ が平行でない部屋の場合や、図１０に示すように、天井Ｔ等に障害物Ｓがある部 屋の場合は、炎式火災感知器を部屋の壁に設置したり、天井Ｔに傾けて設置しな ければならず、その設置場所や設置角度によって監視範囲Ａは変わってしまい、 この監視範囲Ａを確認することは極めて困難であった。また、炎式火災感知器に 使用する受光素子１２の種類等によって監視範囲Ａが異なるので、それぞれの監 視範囲Ａを確認し、その監視範囲Ａに合った設置場所を決めることは大変難しか った。By the way, in such a flame-type fire detector, as shown in FIG. 8, in the case of a room in which the ceiling T and the floor surface Y are parallel to each other, the flame-type fire detector is provided substantially in the center of the ceiling T. It is installed. However, as shown in FIG. 9, for example, in a room where the ceiling T and the floor surface Y are not parallel, such as a gymnasium, or as shown in FIG. The fire detector must be installed on the wall of the room or tilted to the ceiling T, and the monitoring range A changes depending on the installation location and installation angle. It was extremely difficult. Also, since the monitoring range A differs depending on the type of the light receiving element 12 used in the flame-type fire detector, it is very difficult to confirm each monitoring range A and decide the installation location that matches the monitoring range A. It was.
【０００９】 さらに、図９に矢印Ｂで示すような死角部分、つまり、未監視範囲Ｂは、実際 に未監視範囲Ｂから炎を出して炎式火災感知器が作動しなかった時にはじめてわ かるので、この未監視範囲Ｂを事前に発見することは実際問題としてできなかっ た。Further, the blind spot portion as shown by the arrow B in FIG. 9, that is, the unmonitored range B is not found until the flame-type fire detector does not operate because the flame is actually emitted from the unmonitored range B. Therefore, it was not actually possible to discover this unmonitored range B in advance.
【００１０】 この考案は、上記のような課題を解決するためになされたもので、設置される 炎式火災感知器とほぼ同一の監視範囲を有し、この監視範囲を視覚により容易に 確認することのできる炎式火災感知器の検査装置を提供することを目的としたも のである。The present invention has been made to solve the above problems, and has a monitoring range substantially the same as that of the installed flame-type fire detector, and this monitoring range can be easily visually confirmed. The purpose is to provide an inspection device for flame-type fire detectors that can be used.
【００１１】[0011]
この考案に係る炎式火災感知器の検査装置は、本体と上面に透光窓を有し本体 に結合されたカバーとからなる筐体と、筐体内に透光窓に対向して収容された電 気回路部を有するプリント基板と、プリント基板に実装され炎式火災感知器の監 視範囲とほぼ同一の範囲を照射する光源と、透光窓に設けられた光源の光を透過 する透明板とを備えたもの、あるいは、プリント基板に実装された光源と、透光 窓に設けられ光源の光を炎式火災感知器の監視範囲とほぼ同一範囲に照射するレ ンズとを備えたものである。 The flame-type fire detector inspection apparatus according to the present invention is housed in a housing, which has a body and a cover having a light-transmitting window on the upper surface and is connected to the body, and is housed in the housing so as to face the light-transmitting window. A printed circuit board that has an electric circuit, a light source that is mounted on the printed circuit board and illuminates a range that is almost the same as the monitoring range of a flame-type fire detector, and a transparent plate that transmits light from the light source that is installed in a translucent window. Or a light source mounted on a printed circuit board and a lens provided in a light-transmissive window for irradiating the light of the light source to approximately the same range as the monitoring range of the flame-type fire detector. is there.
【００１２】 また、プリント基板に実装された光源と、光源の光を炎式火災感知器の監視範 囲とほぼ同一範囲に照射するように調整する調整手段とを備えたものである。 さらに、光源を点滅するように構成したものである。Further, it is provided with a light source mounted on a printed circuit board and an adjusting means for adjusting the light of the light source to irradiate the light in a range substantially the same as the monitoring range of the flame-type fire detector. Further, the light source is configured to blink.
【００１３】[0013]
炎式火災感知器の検査装置を部屋の天井等に設置し、炎式火災感知器の監視範 囲とほぼ同一範囲に照射する光源を発光させると、光源の光は透明板を透過して 照射範囲、つまり、監視範囲を照射する。そして、視覚によって監視範囲が確認 される。 また、プリント基板に実装された光源と、透光窓に設けられ光源の光を炎式火 災感知器の監視範囲とほぼ同一範囲に照射するレンズとを備えたことにより、炎 式火災感知器の視野角と異なる角度の照射角を有する光源を用いても、視覚によ る監視範囲の確認を行うことができる。 When a flame-type fire detector inspection device is installed on the ceiling of a room and a light source that illuminates the same range as the flame-type fire detector monitoring range is illuminated, the light from the light source passes through the transparent plate and is emitted. Irradiate the range, that is, the monitoring range. Then, the monitoring range is visually confirmed. In addition, by providing a light source mounted on the printed circuit board and a lens provided in the light-transmissive window to irradiate the light from the light source to approximately the same range as the monitoring range of the flame-type fire detector, the flame-type fire detector is provided. The monitoring range can be visually confirmed by using a light source having an irradiation angle different from the viewing angle.
【００１４】 さらに、プリント基板に実装された光源と、光源の光を炎式火災感知器の監視 範囲とほぼ同一範囲に照射するように調整する調整手段とを備えたことにより、 炎式火災感知器の視野角と同じ角度に照射角を容易に調整することができる。 また、光源を点滅するように構成することにより、監視範囲の確認を容易にす る。Further, by providing the light source mounted on the printed circuit board and the adjusting means for adjusting the light from the light source to irradiate the same range as the monitoring range of the flame type fire sensor, the flame type fire sensor is detected. The irradiation angle can be easily adjusted to the same angle as the viewing angle of the vessel. Also, by making the light source blink, the monitoring range can be easily confirmed.

実施例１． 図１はこの考案の第１の実施例の断面図である。なお、図７で説明した従来例 と同じ部分には同じ符号を付し、説明を省略する。図において、１４は炎式火災 感知器の監視範囲Ａとほぼ同一範囲に照射する発光ダイオード（以下、ＬＥＤと 記す）で、プリント基板１０に実装されている。また、このＬＥＤ１４を発光さ せる発光駆動回路はプリント基板１０に設けられており、発光駆動回路のＯＮ、 ＯＦＦは筐体１の外側に設けたスイッチ（図示せず）により操作する構成となっ ている。１５はＬＥＤ１４の可視光線を透過する透明板で、カバー４の透光窓７ に嵌入されている。なお、３ａはプリント基板１０とネジ１１により電気的に接 続され、天井等に設けた炎式火災感知器の取付端子に係合される取付金具である 。 Example 1. FIG. 1 is a sectional view of a first embodiment of the present invention. The same parts as those in the conventional example described with reference to FIG. In the figure, reference numeral 14 is a light emitting diode (hereinafter, referred to as LED) that irradiates the same range as the monitoring range A of the flame type fire detector, and is mounted on the printed circuit board 10. A light emission drive circuit for causing the LED 14 to emit light is provided on the printed circuit board 10, and ON / OFF of the light emission drive circuit is operated by a switch (not shown) provided outside the housing 1. There is. Reference numeral 15 is a transparent plate that transmits visible light of the LED 14, and is fitted into the transparent window 7 of the cover 4. Reference numeral 3a is a mounting member that is electrically connected to the printed circuit board 10 by a screw 11 and is engaged with a mounting terminal of a flame-type fire detector provided on a ceiling or the like.
【００１６】 上記のように構成したこの実施例においては、図２に示すように、検査装置を 部屋の天井Ｔ等の炎式火災感知器の取付け位置に係合させて設置した後、スイッ チをＯＮにしてＬＥＤ１４を発光させると、ＬＥＤ１４の可視光線が透明板１５ を透過して投光され、監視範囲Ａとほぼ同一範囲の照射範囲Ｃ内を照射する。そ して、炎式火災感知器の取付け位置の状態における監視範囲Ａが目視によって確 認される。なお、ＬＥＤ１４は受信機からの信号により点灯させてもよい。In this embodiment configured as described above, as shown in FIG. 2, after the inspection device is installed by engaging with the attachment position of the flame type fire detector such as the ceiling T of the room, the switch is installed. When is turned on and the LED 14 is made to emit light, the visible light of the LED 14 is transmitted through the transparent plate 15 and is projected, so that the irradiation range C which is substantially the same as the monitoring range A is irradiated. Then, the monitoring range A in the state of the mounting position of the flame fire detector is visually confirmed. The LED 14 may be turned on by a signal from the receiver.
【００１７】 実施例２． 図３はこの考案の第２の実施例の断面図である。図において、１６はＬＥＤ１ ４の可視光線を屈折させて透過する凹レンズで、透光窓７に嵌入されている。ま た、このレンズ１６はＬＥＤ１４の照射範囲Ｃが炎式火災感知器の監視範囲Ａと ほぼ同一範囲になるように、屈折時にＬＥＤ１４の照射角βが炎式火災感知器の 視野角αとほぼ同一角度に屈折する屈折率を有し、ＬＥＤ１４は監視範囲Ａと照 射範囲Ｃの差ｄが大きくならない程度にレンズ１６に対向してプリント基板１０ に配設されている。Example 2. FIG. 3 is a sectional view of a second embodiment of the present invention. In the figure, reference numeral 16 denotes a concave lens that refracts and transmits visible light of the LED 14 and is fitted in the light transmitting window 7. Further, in this lens 16, the irradiation angle β of the LED 14 during refraction is almost equal to the viewing angle α of the flame type fire detector so that the irradiation range C of the LED 14 is almost the same range as the monitoring range A of the flame type fire detector. The LED 14 has a refractive index that refracts at the same angle, and the LED 14 is arranged on the printed circuit board 10 so as to face the lens 16 so that the difference d between the monitoring range A and the irradiation range C does not become large.
【００１８】 上記のように構成したこの実施例においても、実施例１と同様に検査装置を部 屋の天井等に設置してＬＥＤ１４を発光させると、ＬＥＤ１４の可視光線Ｅは、 レンズ１６を透過する際、炎式火災感知器の視野角αとほぼ同一角度に屈折して 投光し、照射範囲Ｃ内、つまり、監視範囲Ａとほぼ同じ範囲を照射して炎式火災 感知器の取付け位置における監視範囲Ａの確認を視覚により行う。Also in this embodiment configured as described above, when the inspection device is installed on the ceiling of a building or the like to cause the LED 14 to emit light as in the case of the first embodiment, the visible light E of the LED 14 is transmitted through the lens 16. At that time, the light is refracted at the same angle as the viewing angle α of the flame-type fire detector to project light, and the irradiation range C, that is, the same range as the monitoring range A is irradiated, and the mounting position of the flame-type fire detector is set. The monitoring range A is visually confirmed.
【００１９】 実施例３． 図４はこの考案の第３の実施例の断面図、図５はその要部の拡大図で、実施例 １の係止爪５を省略し、カバー４をネジにより本体２に螺合するようにしたもの である。図において、２ａは本体２の側壁内周に設けられたメネジ、４ａはカバ ー４の円筒部の外周に設けられたオネジで、このオネジ４ａをメネジ２ａに螺合 することによって本体２にカバー４を結合させるとともに、筐体１を設置した後 にもカバー４を上下に移動できる構成となっている。また、カバー４には炎式火 災感知器の視野角αに対応する目盛１７および数値１８（例えば１００゜，８０ ゜，６０゜…）が設けられており、この目盛１７に本体２の開口側の先端部２ｂ を合わせると、ＬＥＤ１４の照射角γが合わせた数値１８に対応した角度に照射 する構成となっている。そして、カバー４を上に移動させるとＬＥＤ１４の照射 角はγ0 と小さくなって照射範囲Ｃが狭くなり、カバー４を下に移動させるとＬ ＥＤ１４の照射角は大きくなって照射範囲Ｃが広くなる。なお、本体２の側壁の 外周にオネジを、またカバー４の円筒部の内周にメネジを設けてもよい。Example 3. FIG. 4 is a sectional view of a third embodiment of the present invention, and FIG. 5 is an enlarged view of a main part thereof, in which the locking claw 5 of the first embodiment is omitted and the cover 4 is screwed onto the main body 2. This is what I did. In the figure, 2a is a female screw provided on the inner circumference of the side wall of the main body 2, and 4a is a male screw provided on the outer circumference of the cylindrical portion of the cover 4. The male screw 2a is screwed onto the female screw 2a to cover the main body 2. The structure is such that the cover 4 can be moved up and down even after the housing 1 is installed while the four are connected. Further, the cover 4 is provided with a scale 17 and a numerical value 18 (for example, 100 °, 80 °, 60 ° ...) Corresponding to the viewing angle α of the flame type fire detector, and the scale 17 has an opening of the main body 2. When the tip portions 2b on the side are combined, the irradiation angle γ of the LED 14 irradiates at an angle corresponding to the combined numerical value 18. Then, when the cover 4 is moved upward, the irradiation angle of the LED 14 is reduced to γ 0 and the irradiation range C is narrowed, and when the cover 4 is moved downward, the irradiation angle of the LED 14 is increased and the irradiation range C is widened. Become. A male thread may be provided on the outer circumference of the side wall of the main body 2, and a female thread may be provided on the inner circumference of the cylindrical portion of the cover 4.
【００２０】 上記のように構成したこの実施例においては、まず、検査装置を部屋の天井等 に設置し、取付ける炎式火災感知器の視野角αが例えば６０゜の場合は、図６に 示すように、カバー４を回転して本体２の先端部２ｂを６０゜の目盛１７に合わ せ、ＬＥＤ１４の照射角γを６０゜に調整する。ついで、ＬＥＤ１４を発光させ ると、ＬＥＤ１４の可視光線は照射角６０゜で投光され、照射範囲Ｃつまり監視 範囲Ａを照射する。そして、目視により監視範囲Ａが確認される。In this embodiment configured as described above, first, when the inspection device is installed on the ceiling of a room or the like and the viewing angle α of the flame-type fire detector to be installed is, for example, 60 °, it is shown in FIG. As described above, the cover 4 is rotated to align the tip portion 2b of the main body 2 with the scale 17 of 60 °, and the irradiation angle γ of the LED 14 is adjusted to 60 °. Then, when the LED 14 is made to emit light, the visible light of the LED 14 is projected at an irradiation angle of 60 °, and the irradiation range C, that is, the monitoring range A is irradiated. Then, the monitoring range A is visually confirmed.
【００２１】 一方、目視により確認した監視範囲Ａが警戒すべき区域において不適切と判断 された場合は、検査装置を取付けた状態で照射角γを調整して適切な角度に修正 したり、あるいは、検査装置の取付け位置を変えて適切な取付け位置を見付ける など監視範囲Ａを訂正することができる。On the other hand, when the visually inspected monitoring range A is determined to be inappropriate in a caution area, the irradiation angle γ is adjusted with the inspection device attached to correct it, or The monitoring range A can be corrected by changing the mounting position of the inspection device to find an appropriate mounting position.
【００２２】 なお、上述の実施例ではＬＥＤ１４の照射角γの調整手段を本体２およびカバ ー４に設け、このカバー４を上下に移動させて照射角γの角度を調整する場合を 例示して説明したが、ＬＥＤ１４の実装したプリント基板を上下に移動させて角 度を変えるようにしてもよい。また、透明板１５を省略してもよく、あるいは、 透明板１５の代わりに凹レンズ１６を用いてもよい。さらに、透光窓７に中心部 に透光部を有し透光窓７の外周に沿って光を通さない部分を備えたリング状の部 材を設けたり、透光窓の構造の違うカバーに代えることにより、光源の照射角を 規制するようにしてもよい。 また、光源にＬＥＤ１４を使用した例を示したが、例えばキセノンランプ等の ハロゲンランプ、豆電球、シールドビーム形電球の如き他の光源を用いてもよく 、あるいは、ＬＥＤ１４を含む上記のような光源を点滅させるパルス発生回路を 設ければ監視範囲Ａの確認がさらに容易となる。また、検査装置の内部に電池を 内蔵することにより、電路工事中でも確実に未監視範囲Ｂを発見できる。In the above-described embodiment, the case where the adjusting means of the irradiation angle γ of the LED 14 is provided in the main body 2 and the cover 4 and the cover 4 is moved up and down to adjust the irradiation angle γ is exemplified. Although explained, the printed board on which the LED 14 is mounted may be moved up and down to change the angle. The transparent plate 15 may be omitted, or the concave lens 16 may be used instead of the transparent plate 15. Further, a ring-shaped member having a light-transmitting portion in the central portion of the light-transmitting window 7 and a portion that does not pass light along the outer periphery of the light-transmitting window 7 may be provided, or a cover having a different structure of the light-transmitting window may be provided. Alternatively, the irradiation angle of the light source may be regulated. Further, although the example in which the LED 14 is used as the light source is shown, other light sources such as a halogen lamp such as a xenon lamp, a miniature bulb, and a shield beam type bulb may be used, or the above-mentioned light source including the LED 14 is used. If a pulse generating circuit for blinking is provided, it becomes easier to confirm the monitoring range A. Further, by incorporating a battery inside the inspection device, the unmonitored range B can be surely found even during electric line construction.

【考案の効果】 以上のようにこの考案では、本体と上面に透光窓を有し本体に結合されたカバ ーとからなる筐体と、筐体内に透光窓に対向して収容された電気回路部を有する プリント基板と、プリント基板に実装され炎式火災感知器の監視範囲とほぼ同一 の範囲を照射する光源と、透光窓に設けられた光源の光を透過する透明板とを備 え、あるいは、プリント基板に実装された光源と、透光窓に設けられ光源の光を 炎式火災感知器の監視範囲とほぼ同一範囲に照射するレンズとを備えたので、炎 式火災感知器の取付け位置における監視範囲を視覚によって簡単に確認すること ができる。 また、設置時において、未監視範囲を未然に発見することができるとともに、 感知器として致命的な火災を検出できないという失報状態をも未然に防止するこ とができる。As described above, according to the present invention, the housing including the main body and the cover having the transparent window on the upper surface and coupled to the main body, and the housing is housed inside the housing so as to face the transparent window. A printed circuit board that has an electric circuit, a light source that is mounted on the printed circuit board, illuminates a range that is almost the same as the monitoring range of the flame-type fire detector, and a transparent plate that is provided in the translucent window and that transmits the light from the light source. It is equipped with or equipped with a light source mounted on a printed circuit board and a lens provided in a translucent window to illuminate the light of the light source in the same range as the monitoring range of the flame type fire detector. The monitoring range at the mounting position of the vessel can be easily confirmed visually. In addition, it is possible to detect the unmonitored area at the time of installation, and to prevent a false alarm that the sensor cannot detect a fatal fire.
【００２４】 さらに、プリント基板に実装された光源と、光源の光を炎式火災感知器の監視 範囲とほぼ同一範囲に照射するように調整する調整手段とを備えたので、１つの 検査装置でそれぞれの違った視野角とほぼ同じ角度に照射角を容易に調整するこ とができて便利である。また、警戒区域に合った炎式火災感知器の取付け位置と 視野角に修正することができるとともに、監視範囲の重複を未然に防ぐことがで きる。 また、光源を点滅するように構成したので、監視範囲の確認がさらに容易とな った。Further, since the light source mounted on the printed circuit board and the adjusting means for adjusting the light from the light source to irradiate the light in the almost same range as the monitoring range of the flame-type fire detector are provided, one inspection device can be used. It is convenient because the irradiation angle can be easily adjusted to almost the same angle as each different viewing angle. In addition, it is possible to correct the installation position and viewing angle of the flame-type fire detector that match the warning area, and it is possible to prevent duplication of the monitoring range. Also, since the light source is configured to blink, it is easier to check the monitoring range.
