Description

本発明は加煙感知器および加煙感知器の試験方法に係り、例えば、天井などの高所に設置された加煙感知器の総合的機能を試験することができる加煙感知器および加煙感知器の試験方法に関する。   The present invention relates to a smoke detector and a method for testing the smoke detector, for example, a smoke detector and a smoke detector capable of testing the overall function of the smoke detector installed at a high place such as a ceiling. The present invention relates to a test method for a sensor.

建物の天井などに設置された加煙感知器は、火災受信機に接続されて火災警報システムを構成し、加煙感知器が煙を感知すると感知信号を出力して火災警報システムが警報を発する。火災警報システムは、所定の期間ごとに機器の正常作動を試験する必要がある。従来より、加煙感知器の作動試験は、線香などの燃焼に伴う煙を利用するものや、ガスボンベから噴射させた試験ガスを用い、天井に取り付けられている加煙感知器に実際に煙（試験ガス）を作用させることにより作動試験が行われる。屋内スポーツ施設、ホール、工場などの高天井に設置された加煙感知器は、足場を組んで試験作業が行われていたが、このような煩雑な点検作業や、高所作業のリスクを回避するため、ワイヤ、ベルト等の吊り材を介して煙感知器を昇降装置に昇降自在に吊下げて配設し、地上で試験作業が行えるようにした昇降装置が知られている（例えば特許文献１、２参照）。
特許第３６７７１６１号公報 特開２００１−２８０８３号公報 A smoke detector installed on the ceiling of a building is connected to a fire receiver to form a fire alarm system. When the smoke detector detects smoke, it outputs a detection signal and the fire alarm system issues an alarm. . Fire alarm systems need to test the normal operation of the equipment at regular intervals. Conventionally, smoke detectors have been tested for operation using smoke generated by burning, such as incense sticks, and test gases injected from gas cylinders. An operation test is performed by applying a test gas. Smoke detectors installed on high ceilings in indoor sports facilities, halls, factories, etc. have been tested with a scaffold, but avoiding the risk of such complicated inspection work and work in high places Therefore, a lifting device is known in which a smoke detector is suspended from a lifting device via a lifting material such as a wire or a belt so as to be lifted and lowered so that a test operation can be performed on the ground (for example, Patent Documents). 1 and 2).
Japanese Patent No. 3677161 JP 2001-28083 A

ところで、特許文献１及び特許文献２に記載の昇降装置は、昇降装置に配置された固定接点と、ワイヤに吊下げられた昇降部（煙感知器）に配置された給電接点とを備え、昇降部が上昇した定常位置にあるときには、固定接点と給電接点とが接続されて昇降部に配置された煙感知器に電力を供給している。従って、煙感知器の試験のために昇降部を下降させると、固定接点と給電接点との接続が遮断され、煙感知器への電力供給がなされなくなる。   By the way, the lifting device described in Patent Document 1 and Patent Document 2 includes a fixed contact disposed in the lifting device and a power supply contact disposed in a lifting part (smoke detector) suspended from a wire. When the unit is in the raised normal position, the fixed contact and the power supply contact are connected to supply power to the smoke detector disposed in the elevating unit. Therefore, when the elevating part is lowered for the test of the smoke detector, the connection between the fixed contact and the power supply contact is interrupted, and the power supply to the smoke detector is not performed.

一方、火災警報システムは、煙感知器だけでなくシステム全体として正常に作動することを総合的に試験する必要がある。煙感知器が配設された昇降部を下降させて行う、電力供給が遮断された状態での試験では、煙感知器単体の検査は行えるものの、システム全体の総合検査を行うことができないという不都合があった。このような総合検査を行うには、煙感知器が上昇位置にある電力供給された状態で試験を行わなければならず、煙感知器が屋内スポーツ施設、ホール、工場などの高天井に設置されている場合、足場を組んで高所作業を行う必要があり、これに伴うリスク、費用の観点から改善の余地があった。   On the other hand, it is necessary to comprehensively test that the fire alarm system operates normally as a whole system, not just the smoke detector. In the test where the power supply is cut off by lowering the elevating part where the smoke detector is installed, the smoke detector itself can be inspected, but the overall system cannot be inspected. was there. In order to perform such comprehensive inspections, the smoke detector must be tested with the power supplied in the raised position, and the smoke detector is installed on a high ceiling in indoor sports facilities, halls, factories, etc. However, there is room for improvement in terms of the risks and costs associated with it.

本発明は、前述した問題点に鑑みてなされたものであり、その目的は、加煙感知器が高天井に設置された火災警報システムの総合試験を地上で安全かつ容易に行うことができる加煙感知器および加煙感知器の試験方法を提供することにある。   The present invention has been made in view of the above-described problems, and an object of the present invention is to enable a comprehensive test of a fire alarm system in which a smoke detector is installed on a high ceiling to be safely and easily performed on the ground.

前述した目的を達成するために、本発明は、所定高さに設置される昇降装置と、前記昇降装置に懸架されて昇降可能な煙感知部と、前記煙感知部が所定高さの定常位置にあるときに前記煙感知部に対して電気的に接続される接続部とを備える加煙感知器であって、前記煙感知部に対して着脱可能な煙発生部を有することを特徴としている。   In order to achieve the above-described object, the present invention provides an elevating device installed at a predetermined height, a smoke detecting unit suspended by the elevating device, and a steady position where the smoke detecting unit is at a predetermined height. A smoke detector having a connection portion electrically connected to the smoke detector when the smoke detector is attached to the smoke detector. .

このように構成された加煙感知器においては、昇降装置に懸架されて昇降可能な煙感知部に対して、着脱自在とされた煙発生部が設けられている。これにより、高天井などの高所に加煙感知器が配置されていても、足場などを組むことなく、昇降装置によって煙感知部を地上まで下降させ、煙発生部を安全且つ容易に煙感知部に取り付けることができる。また、昇降装置は、煙感知部が所定高さの定常位置にあるときに煙感知部に対して電気的に接続される接続部を備えるので、地上において煙感知部に煙発生部を取り付けた後、煙感知部を定常位置まで上昇させて昇降装置と煙感知部との接続部を電気的に接続させ、加煙感知器の試験準備を行うことができる。   In the smoke detector configured as described above, a smoke generating unit that is detachable from the smoke detecting unit that is suspended by the lifting device and can be moved up and down is provided. As a result, even if a smoke detector is placed in a high place such as a high ceiling, the smoke detector is lowered to the ground by the lifting device without using a scaffolding, etc., and the smoke generator can be detected safely and easily. Can be attached to the part. Further, since the lifting device includes a connection portion that is electrically connected to the smoke detection unit when the smoke detection unit is in a steady position at a predetermined height, the smoke generation unit is attached to the smoke detection unit on the ground. Thereafter, the smoke detector is raised to a steady position, and the connection between the lifting device and the smoke detector is electrically connected to prepare the smoke detector for testing.

従って、この加煙感知器においては、高所に配置された加煙感知器の機能を、地上で安全且つ容易に試験することができ、従来のような足場などを組まなければ煙感知部に通電した状態での総合試験ができないという問題を解消できることになる。   Therefore, in this smoke detector, the function of the smoke detector placed at a high place can be tested safely and easily on the ground. This solves the problem that a comprehensive test cannot be performed in the energized state.

また、本発明は、前記煙発生部が前記煙感知部に取り付けられた状態で発煙可能であることを特徴としている。   Further, the present invention is characterized in that smoke can be emitted in a state where the smoke generator is attached to the smoke detector.

このように構成された加煙感知器においては、煙発生部が取り付けられた煙感知部を所定高さの定常位置に位置させて煙発生部から発煙させるようにすれば、加煙感知器の機能を、地上で安全且つ容易に試験することができる。   In the smoke detector configured as described above, if the smoke detector to which the smoke generator is attached is positioned at a steady position at a predetermined height so as to emit smoke from the smoke generator, Function can be tested safely and easily on the ground.

また、本発明は、所定高さに設置される昇降装置と、前記昇降装置に懸架されて昇降可能な煙感知部と、前記煙感知部が所定高さの定常位置にあるときに前記煙感知部に対して電気的に接続される接続部とを備える加煙感知器の試験方法であって、前記煙感知部を前記定常位置から下降させ、発煙可能な煙発生部を前記煙感知部に取り付けた後、前記煙感知部を前記定常位置まで上昇させて前記煙感知部を前記接続部に接続させることにより、前記煙発生部から発生する煙を前記煙感知部に感知させることを特徴としている。   The present invention also provides a lifting device installed at a predetermined height, a smoke detection unit suspended by the lifting device and capable of moving up and down, and the smoke detection unit when the smoke detection unit is in a steady position at a predetermined height. A smoke detector having a connection part electrically connected to a part, wherein the smoke sensor is lowered from the steady position, and a smoke generator capable of generating smoke is added to the smoke sensor. After the mounting, the smoke detection unit is raised to the steady position and the smoke detection unit is connected to the connection unit, thereby causing the smoke detection unit to detect smoke generated from the smoke generation unit. Yes.

このような加煙感知器の試験方法においては、煙感知部を定常位置から下降させ、煙発生部を煙感知部に取り付けた後、定常位置まで上昇させて接続部によって煙感知部と昇降装置とを電気的に接続させ、煙発生部から煙を発生させて煙感知部で感知させるようにしたので、高所に配置された加煙感知器の機能を、地上で安全且つ容易に試験することができ、従来のような足場などを組まなければ煙感知部に通電した状態での総合試験ができないという問題を解消できることになる。   In such a smoke detector test method, the smoke detector is lowered from the steady position, the smoke generator is attached to the smoke detector, and then raised to the steady position, and the smoke detector and the lifting device are connected by the connecting portion. Are connected to each other, smoke is generated from the smoke generator and detected by the smoke detector, so that the function of the smoke detector placed at a high place can be tested safely and easily on the ground. It is possible to solve the problem that a comprehensive test cannot be performed in a state in which the smoke detection unit is energized unless a conventional scaffold is assembled.

本発明によれば、従来のような足場などを組まなければ煙感知部に通電した状態での総合試験ができないという問題を解消でき、これにより天井などの高所に配置された加煙感知器の機能を、地上で安全且つ容易に試験することができるという効果が得られる。   According to the present invention, it is possible to solve the problem that a comprehensive test cannot be performed in a state in which the smoke detection unit is energized unless a conventional scaffolding is provided, thereby enabling a smoke detector disposed at a high place such as a ceiling. It is possible to obtain an effect that the function of the above can be safely and easily tested on the ground.

先ず、加煙感知器について説明する。図１及び図２に示すように、加煙感知器１は、固定金具２を介して屋内スポーツ施設、ホール、工場などの高天井に設置される昇降装置３と、昇降装置３から繰り出され、或いは巻き取られるワイヤ４によって、昇降装置３に昇降自在に懸架される昇降体５とを備える。昇降体５には、煙を感知したとき感知信号を出力する煙感知部６が配設されている。昇降装置３は、その内部にモータ、及び該モータによって回転する巻取りドラム（いずれも図示せず）を備え、巻取りドラムの回転によりワイヤ４を巻き取り、或いは繰り出して昇降体５を上昇、或いは下降させる。   First, the smoke detector will be described. As shown in FIG. 1 and FIG. 2, the smoke detector 1 is drawn out from the lifting device 3 and the lifting device 3 installed on the high ceiling of an indoor sports facility, hall, factory, etc. via the fixing bracket 2. Alternatively, an elevating body 5 that is suspended by the elevating device 3 so as to be movable up and down by a wound wire 4 is provided. The elevating body 5 is provided with a smoke detection unit 6 that outputs a detection signal when smoke is detected. The lifting device 3 includes a motor and a winding drum (not shown) that is rotated by the motor, and the winding device 5 winds up or feeds the wire 4 by the rotation of the winding drum, and lifts the lifting body 5. Or lower.

このような加煙感知器１は、通常、１つの建物内に複数台が設置されており、その電気回路は、図３に示すようになっている。即ち、昇降装置３は、第１の入側固定接点７ａ、第２の入側固定接点７ｃ、第１の出側固定接点７ｂおよび第２の出側固定接点７ｄを有する。第１の入側固定接点７ａおよび第２の入側固定接点７ｃは火災受信機に接続される。第１の出側固定接点７ｂおよび第２の出側固定接点７ｄは送り配線９に接続される。   A plurality of such smoke detectors 1 are usually installed in one building, and the electric circuit thereof is as shown in FIG. That is, the lifting / lowering device 3 has a first entry side fixed contact 7a, a second entry side fixed contact 7c, a first exit side fixed contact 7b, and a second exit side fixed contact 7d. The first incoming fixed contact 7a and the second incoming fixed contact 7c are connected to the fire receiver. The first outgoing fixed contact 7 b and the second outgoing fixed contact 7 d are connected to the feed wiring 9.

昇降装置３′も同じ構成であり、第１の入側固定接点７ａおよび第２の入側固定接点７ｃは送り配線９に接続され、第１の出側固定接点７ｂおよび第２の出側固定接点７ｄは送り配線９′に接続される。同様にして、送り配線９′にさらに別の昇降装置（図示せず）が接続され、終端に終端器が接続される。すなわち、火災受信機と終端器との間に複数の昇降装置３が縦続接続される。   The lifting / lowering device 3 'has the same configuration, and the first incoming fixed contact 7a and the second incoming fixed contact 7c are connected to the feed wiring 9, and the first outgoing fixed contact 7b and the second outgoing fixed. The contact 7d is connected to the feed wiring 9 '. Similarly, another lifting device (not shown) is connected to the feed wiring 9 ', and a terminator is connected to the end. That is, a plurality of lifting devices 3 are cascaded between the fire receiver and the terminator.

また巻取りドラムを回転させるモータＭには、正転（上昇）用、逆転（下降）用および共通の電源線が接続されている。したがって、電源線に接続されたスイッチ（図示せず）の動作によりモータＭを正転または逆転させて、ワイヤ４を巻き取り、或いは繰り出して、昇降体５を上昇または下降させる。そして昇降体５の最上昇位置（定常位置）では煙感知態勢となり、下降位置では点検できる状態となる。   The motor M that rotates the winding drum is connected to a normal power supply line for forward rotation (up), reverse rotation (downward), and common. Therefore, the motor M is rotated forward or reverse by the operation of a switch (not shown) connected to the power supply line, and the wire 4 is wound or fed out to raise or lower the lifting body 5. The smoke detection posture is at the highest position (steady position) of the lift 5 and the inspection is possible at the lowered position.

昇降体５は、上昇した定常位置において、第１の入側固定接点７ａに接触する第１の入側給電接点８ａ、第２の入側固定接点７ｃに接触する第２の入側給電接点８ｃ、第１の出側固定接点７ｂに接触する第１の出側給電接点８ｂおよび第２の出側固定接点７ｄに接触する第２の出側給電接点８ｄを有する。   The elevating body 5 has a first incoming feed contact 8a in contact with the first incoming fixed contact 7a and a second incoming feed contact 8c in contact with the second incoming fixed contact 7c at the raised normal position. The first output side power supply contact 8b is in contact with the first output side fixed contact 7b, and the second output side power supply contact 8d is in contact with the second output side fixed contact 7d.

煙感知部６は、昇降体５に取付けられて第１の入側給電接点８ａと第２の入側給電接点８ｃとの間に接続されている。また接続部２８により、第１の入側給電接点８ａと第１の出側給電接点８ｂの相互間、および第２の入側給電接点８ｃと第２の出側給電接点８ｄの相互間をそれぞれ接続している。これにより、昇降装置３は、固定接点７ａ〜７ｄおよび給電接点８ａ〜８ｄを通して火災受信機側と送り配線９とを接続し、昇降装置３′は、固定接点７ａ〜７ｄおよび給電接点８ａ〜８ｄを通して送り配線９と送り配線９′とを接続している。   The smoke sensing unit 6 is attached to the elevating body 5 and connected between the first incoming power supply contact 8a and the second incoming power supply contact 8c. Further, the connection portion 28 allows the first input side power supply contact 8a and the first output side power supply contact 8b to be connected to each other, and the second input side power supply contact 8c and the second output side power supply contact 8d to be connected to each other. Connected. As a result, the lifting device 3 connects the fire receiver side and the feed wiring 9 through the fixed contacts 7a to 7d and the feeding contacts 8a to 8d, and the lifting device 3 'is connected to the fixed contacts 7a to 7d and the feeding contacts 8a to 8d. The feed wiring 9 and the feed wiring 9 'are connected through the through-hole.

このように、火災受信機と終端器との間を接続する電源供給線の送り配線９、９′が煙感知部６を通して行なわれるように配線されるとともに、煙感知部６が作動したとき、感知信号が火災受信機に送られるように配線されている。   In this way, the feed lines 9 and 9 'of the power supply line connecting between the fire receiver and the terminator are wired so as to be performed through the smoke detection unit 6, and when the smoke detection unit 6 is activated, It is wired so that the sensing signal is sent to the fire receiver.

したがって、昇降体５がモータＭによって上昇して定常位置にある場合は、各固定接点７ａ〜７ｄと各給電接点８ａ〜８ｄが接触して煙感知部６に電力が供給され、煙感知部６が煙を感知して動作すると、火災受信機に感知信号が送信される。また昇降体５がモータＭによって床面の手元まで下降した場合は、煙感知部６に後述する煙発生部１０の取り付けが可能となる。このとき、固定接点７ａ〜７ｄと給電接点８ａ〜８ｄとは離間しているため、火災受信機からの電力は供給されず、システム全体の電源供給が断たれる。   Therefore, when the elevating body 5 is raised by the motor M and is in a steady position, the fixed contacts 7a to 7d and the power supply contacts 8a to 8d come into contact with each other to supply electric power to the smoke detector 6, and the smoke detector 6 When the sensor detects smoke, it sends a detection signal to the fire receiver. When the elevating body 5 is lowered to the floor surface by the motor M, it is possible to attach a smoke generating unit 10 described later to the smoke detecting unit 6. At this time, since the fixed contacts 7a to 7d and the power supply contacts 8a to 8d are separated from each other, the power from the fire receiver is not supplied and the power supply of the entire system is cut off.

また、昇降装置３、３′のいずれかの異常で煙感知部６への電源供給ができなくなった場合、すなわち接点７ａ〜７ｄ、８ａ〜８ｄが開離した場合、配線を昇降体５側で送っているため、システム全体の電源供給が断たれ、異常が検知される。   Further, when the power supply to the smoke detector 6 cannot be performed due to any abnormality of the lifting devices 3 and 3 ', that is, when the contacts 7a to 7d and 8a to 8d are separated, the wiring is connected to the lifting body 5 side. As a result, the power supply to the entire system is cut off and an abnormality is detected.

尚、上記説明においては、複数の昇降装置３、３′が設けられた場合の電気回路について説明したが、昇降装置３の設置台数が１台であっても、同様の電気回路となる。   In the above description, the electric circuit in the case where a plurality of lifting devices 3 and 3 ′ are provided has been described. However, even if the number of lifting devices 3 is one, the same electrical circuit is obtained.

図４から図６に示すように、昇降体５の上面５ａには、金属板が略コの字型に形成された取付金具１６が、その両側壁１７を下方に向けて固定されている。両側壁１７には、略Ｌ字型の係合溝１８が互いに対向して形成されている。   As shown in FIGS. 4 to 6, a mounting bracket 16 in which a metal plate is formed in a substantially U shape is fixed to the upper surface 5 a of the elevating body 5 with its both side walls 17 facing downward. On both side walls 17, substantially L-shaped engaging grooves 18 are formed so as to face each other.

煙発生部１０は、上面に開口１２を有する略有底円筒形のハウジング１１を備える。ハウジング１１の外側面には、先端部２０が略Ｌ字型に折り曲げ形成された一対の係止片１９が固定されている。ハウジング１１の内部空間１５には、ガスボンベ１３が収容されており、噴射ボタン２２が押圧されたとき、煙感知部６の作動を確認するための試験ガス１４を噴射する。ハウジング１１の開口１２の大きさは、煙感知部６の直径より大きく、煙感知部６が開口１２から挿入されて内部空間１５に収容可能となっている。また、ハウジング１１の外側面には、直径方向に貫通する一対の孔２１が設けられている。   The smoke generator 10 includes a substantially bottomed cylindrical housing 11 having an opening 12 on the upper surface. On the outer surface of the housing 11, a pair of locking pieces 19 in which the distal end portion 20 is bent in a substantially L shape are fixed. A gas cylinder 13 is accommodated in the internal space 15 of the housing 11, and when the injection button 22 is pressed, the test gas 14 for confirming the operation of the smoke detector 6 is injected. The size of the opening 12 of the housing 11 is larger than the diameter of the smoke detection unit 6, and the smoke detection unit 6 is inserted from the opening 12 and can be accommodated in the internal space 15. A pair of holes 21 penetrating in the diametrical direction is provided on the outer surface of the housing 11.

そして、図５に示すように、煙発生部１０は、煙感知部６を開口１２に挿入しながら、係止片１９の先端部２０を、両側壁１７の係合溝１８に矢印Ａ方向に挿入し、更に矢印Ｂ方向に水平に移動させることによって取付金具１６に係止させ、煙感知部６を内部空間１５に収容した状態で昇降体５（煙感知部６）に取り付けられる。   Then, as shown in FIG. 5, the smoke generating unit 10 inserts the smoke detecting unit 6 into the opening 12, and moves the tip 20 of the locking piece 19 in the engagement groove 18 of the side walls 17 in the direction of arrow A. It is inserted and further moved horizontally in the direction of arrow B to be locked to the mounting bracket 16, and attached to the elevating body 5 (smoke detecting unit 6) while the smoke detecting unit 6 is accommodated in the internal space 15.

また、図６に示すように、煙発生部１０は、略コの字型に形成された押圧レバー２３を備える。押圧レバー２３は、一対の脚部２４と、該一対の脚部２４を連結する連結部２５とにより略コの字型に形成されており、連結部２５がガスボンベ１３の噴射ボタン２２上に配置されてハウジング１１の外側面を貫通する一対の孔２１に挿通されている。押圧レバー２３の両脚部２４は、上方に向かって配置されており、その長さは噴射ボタン２２の上面から昇降体５の取付金具１６の上面までの長さより、わずかに長く設定されている。   Moreover, as shown in FIG. 6, the smoke generation part 10 is equipped with the press lever 23 formed in the substantially U shape. The pressing lever 23 is formed in a substantially U shape by a pair of leg portions 24 and a connecting portion 25 that connects the pair of leg portions 24, and the connecting portion 25 is disposed on the injection button 22 of the gas cylinder 13. And inserted into a pair of holes 21 penetrating the outer surface of the housing 11. Both leg portions 24 of the pressing lever 23 are arranged upward, and the length thereof is set slightly longer than the length from the upper surface of the injection button 22 to the upper surface of the mounting bracket 16 of the lifting body 5.

上記した煙発生部１０による加煙感知器１の作動試験は、次のように行われる。即ち、図示しない制御装置を操作して高天井に設置された昇降装置３のモータＭを回転させ、巻取りドラムからワイヤ４を繰り出して昇降体５を下降させる。このとき、昇降装置３と昇降体５の接点７ａ〜７ｄ、８ａ〜８ｄは非接触状態となり、煙感知部６への電力供給が遮断される。   The operation test of the smoke detector 1 by the smoke generating unit 10 is performed as follows. That is, the controller M (not shown) is operated to rotate the motor M of the lifting device 3 installed on the high ceiling, and the wire 4 is fed out from the winding drum to lower the lifting body 5. At this time, the contacts 7 a to 7 d and 8 a to 8 d between the lifting device 3 and the lifting body 5 are in a non-contact state, and the power supply to the smoke detection unit 6 is interrupted.

そして、地上まで下降させた昇降体５の取付金具１６の係合溝１８に、煙発生部１０の係止片１９を矢印Ａ方向に挿入し、更に矢印Ｂ方向に水平に移動させて取付金具１６に係止する。これにより、煙感知部６が煙発生部１０の内部空間１５に収容された状態で、煙発生部１０が昇降体５（煙感知部６）に取り付けられる。この取付け作業は、昇降体５が地上まで下降した低い位置で行われ、且つ昇降体５と煙発生部１０とは、取付金具１６と係止片１９とを係合させることによって着脱自在となっているので、極めて容易に行うことができる。   Then, the engaging piece 19 of the smoke generating part 10 is inserted in the direction of the arrow A in the engaging groove 18 of the mounting bracket 16 of the lifting body 5 lowered to the ground, and further moved horizontally in the direction of the arrow B to attach the mounting bracket. 16 is locked. Thereby, the smoke generation part 10 is attached to the raising / lowering body 5 (smoke detection part 6) in the state in which the smoke detection part 6 was accommodated in the internal space 15 of the smoke generation part 10. This attachment work is performed at a low position where the elevating body 5 is lowered to the ground, and the elevating body 5 and the smoke generating unit 10 are detachable by engaging the mounting bracket 16 and the locking piece 19. Therefore, it can be performed very easily.

次いで、制御装置を操作して巻取りドラムでワイヤ４を巻き取り、昇降体５を元の定常位置まで上昇させると、押圧レバー２３の両脚部２４の先端が天井２６に当接して押圧レバー２３を押し下げる。これにより、ガスボンベ１３の噴射ボタン２２が、押圧レバー２３の連結部２５によって押圧されてガスボンベ１３から試験ガス１４が噴出する。   Next, when the control device is operated to wind the wire 4 with the take-up drum and raise the elevating body 5 to the original steady position, the tips of both leg portions 24 of the press lever 23 come into contact with the ceiling 26 and the press lever 23. Press down. Thereby, the injection button 22 of the gas cylinder 13 is pressed by the connecting portion 25 of the pressing lever 23, and the test gas 14 is ejected from the gas cylinder 13.

ガスボンベ１３から試験ガス１４が噴出されると同時に、或いは若干遅れて、昇降装置３の固定接点７ａ〜７ｄと、昇降体５の給電接点８ａ〜８ｄとが接触して、電力が昇降体５（煙感知部６）に供給される。これにより、煙感知部６は、ガスボンベ１３から噴出した試験ガス１４を感知して感知信号を出力して火災受信機に送信し、火災警報システムが警報を発する。   At the same time when the test gas 14 is ejected from the gas cylinder 13 or with a slight delay, the fixed contacts 7a to 7d of the lifting / lowering device 3 and the power supply contacts 8a to 8d of the lifting / lowering body 5 come into contact with each other. Supplied to the smoke detector 6). As a result, the smoke detector 6 detects the test gas 14 ejected from the gas cylinder 13 and outputs a detection signal to transmit it to the fire receiver, and the fire alarm system issues an alarm.

以上の操作により、加煙感知器１が正常作動することを確認した後、再び、制御装置を操作して昇降装置３のモータＭを回転させ、昇降体５を下降させる。このとき、昇降体５の下降に伴って押圧レバー２３が天井２６から離れると、押圧レバー２３による噴射ボタン２２の押圧が解除されるので、ガスボンベ１３からの試験ガス１４の噴出が停止する。そして、昇降体５を更に降下させ、先とは逆の手順で煙発生部１０を昇降体５（煙感知部６）から取り外す。次いで、昇降体５を元の定常位置まで上昇させて試験を終了する。   After confirming that the smoke detector 1 operates normally by the above operation, the controller 5 is operated again to rotate the motor M of the elevating device 3 and lower the elevating body 5. At this time, when the pressing lever 23 moves away from the ceiling 26 as the elevating body 5 descends, the pressing of the injection button 22 by the pressing lever 23 is released, so that the ejection of the test gas 14 from the gas cylinder 13 stops. And the raising / lowering body 5 is further lowered | hung, and the smoke generation part 10 is removed from the raising / lowering body 5 (smoke detection part 6) in the reverse procedure. Next, the lifting body 5 is raised to the original steady position, and the test is terminated.

従来、昇降体５（煙感知部６）を下降させた状態での試験では、煙感知部６への電力供給が遮断されるため、煙感知部６単体の部分的な作動試験しか行えなかったが、前述した本発明の加煙感知器１によれば、火災警報システム全体の総合試験を行うことができ、信頼性の高い作動試験が可能となる。   Conventionally, in a test in a state where the lifting body 5 (smoke detection unit 6) is lowered, power supply to the smoke detection unit 6 is interrupted, so that only a partial operation test of the smoke detection unit 6 can be performed. However, according to the smoke detector 1 of the present invention described above, a comprehensive test of the entire fire alarm system can be performed, and a reliable operation test can be performed.
