Description

  The present invention relates to a test device for a fire detector.

  2. Description of the Related Art Conventionally, there is a test apparatus that is installed in a facility such as a building and performs a test by operating a spot-type fire detector that detects a fire based on heat, smoke, and the like accompanying a fire. Such test devices include, for example, a heating tester and a smoke tester, the former for heating and operating a heat-sensitive fire detector, and the latter for operating a smoke-detection fire detector. Each fire detector is tested by injecting an aerosol, for example an aerosol containing liquid paraffin, into the fire detector.

  In these test devices, a hood is generally attached to the top of the test device body that generates heat or aerosol for operating the fire detector, and this is brought into contact with a mounting surface (for example, a ceiling surface) of the fire detector to be tested. Cover around the fire detector. Thus, the fire detector is efficiently operated by forming a closed space around the fire detector to be tested and applying heat or aerosol (for example, see Patent Document 1).

  On the other hand, fire detectors are generally formed in a generally cylindrical shape having a low height, and an operation indicator light for indicating the fact when activated, or a light emitting area of the operation indicator lamp is provided at a peripheral portion of the fire sensor. (For example, see Patent Document 2). If the hood provided in the test device is formed of a transparent or translucent material, the operation confirmation lamp can be visually recognized. Then, the tester who tests the fire detector using the test apparatus can confirm the operation of the fire detector by visually confirming the operation confirmation light of the fire detector tested by himself through the hood.

  However, when a test is performed from directly below a fire detector using a conventional test device, the fire detector becomes a blind spot in the test device main body and cannot directly recognize the operation confirmation light from the tester. For this reason, the test may not be able to be performed by one person, and a measure such as performing the test with a plurality of persons was required. In addition, even after the fire detector was activated, if the tester who could not visually recognize the operation confirmation light continued to operate without recognizing that it had been activated, the test equipment was wasted and time wasted. .

  In view of the above circumstances, it is an object of the present invention to provide a test device that allows a tester to directly view an operation confirmation lamp even when an operation test is performed from directly below a fire detector.

  The present invention includes a main body having an actuation means for operating a fire detector, and a hood provided on a top of the main body and having a cylindrical portion covering at least a periphery of the fire detector. A test device used by attaching the main body to the tip of a support rod that supports the fire detector, wherein at least a part or the whole of the bottom of the hood is formed of a light-transmitting member, and a tester directly below the hood forms a hood. A non-protruding portion that does not protrude directly below the translucent member is provided on the side of the main body so as not to block the line of sight to the operation confirmation light provided in the fire detector of the test object via the translucent member. A test apparatus characterized in that:

  Further, the present invention is the test apparatus, wherein a shape of the main body projected directly below the main body is substantially rectangular, and a short side of the main body is located inside a bottom peripheral edge of the hood.

  Further, the present invention is the test apparatus, wherein a plurality of protrusions projecting outward are provided on the outer periphery of the hood and / or the outer periphery of the main body.

  Further, the present invention is the test apparatus, wherein the protrusion is formed of an elastic body and includes a protrusion for absorbing an impact on the hood and / or the main body.

  According to this invention, a space located immediately below the translucent member is formed on the side of the non-projecting portion of the main body. The space does not obstruct the line of sight from the tester immediately below the fire detector to the operation confirmation light provided on the fire detector to be tested via the translucent member. Thus, the tester himself / herself can visually recognize the operation confirmation lamp of the fire detector under test through the space on the side of the non-projecting portion of the main body and the translucent member even from directly below the fire detector. That is, the tester himself can recognize the operation of the fire detector during the test. As a result, a fire detector operation test can be performed by one person.

  Therefore, according to the present invention, even if the operation test is performed from directly below the fire detector, it is possible to obtain a test apparatus in which one tester himself can directly visually recognize the operation confirmation light of the fire detector.

  Further, according to the present invention, the shape of the main body projected directly below is substantially rectangular, and the short side is positioned inside the bottom peripheral edge of the hood. The space formed on the side of the fire detector shall be large enough not to obstruct the line of sight from the tester directly below to the operation confirmation light provided on the fire detector to be tested via a translucent member. However, a sufficient volume of the main body can be ensured.

  Further, according to the present invention, by providing a plurality of projections projecting outward on the outer periphery of the hood and / or the outer periphery of the main body, it is possible to prevent the test apparatus from rolling due to the projections. . For example, the test device can be prevented from rolling when placed on the floor.

  Further, according to the present invention, the projection is made of an elastic body and includes a projection that absorbs an impact on the hood and / or the main body. Alternatively, the impact on the main body can be prevented. For example, it is possible to prevent the hood and / or the main body from being impacted even if the test apparatus falls.

  An embodiment of the present invention will be described with reference to FIGS. 1 to 7 by taking, as an example, a case in which the present invention is applied to a heating tester which heats a heat-sensitive fire detector and performs an operation test. The present invention can be applied to a test device for performing various operation tests for a fire detector. That is, various heating testers for heat-sensitive fire detectors, for example, using benzene, heating by the heat of the catalytic reaction using platinum as a catalyst, heating by hot water, heating by the chemical reaction heat of slaked lime, The present invention can be applied to a device heated by a heater driven by electric power. Further, the present invention can be applied not only to such a heating tester, but also to a smoke detector for a smoke detection type fire detector, for example, a smoke detector for injecting aerosol. The test device to which the present invention can be applied is not limited to the above-described heating test device or smoke test device, but can be applied to a test device for performing an operation test of a spot-type fire detector having an operation confirmation light. is there.

  First, the outline of the configuration of the heating tester 1 according to the present invention and the appearance of the operation test of the fire detector D by the heating tester 1 attached to the tip of the support rod 5 will be briefly described with reference to FIG. explain. The fire detector D to be tested by the heating tester 1 is a heat-sensitive spot-type fire detector, such as a constant-temperature spot-type detector, a differential-type spot-type detector, and a compensation-type spot-type detector. Vessels.

  The heating tester 1 includes a main body 2, a hood 3 provided on the top of the main body 2, and a bracket 4 for rotatably supporting the main body 2, and for supporting the main body 2 toward the fire detector D. It is used by attaching to the tip of the support rod 5. Then, for example, when performing an operation test of the fire detector D installed on the ceiling surface C, the tester H supports the main body 2 toward the fire detector D with the support rod 5 and the fire detector with the hood 3. While covering D, its upper end is brought into contact with the ceiling surface C, and an operation test is performed in that state (see FIG. 1). The hood 3 may cover the periphery of the sensing unit of the fire detector D instead of covering the entire fire detector D. According to the heating tester 1, although the details will be described later, even when the operation test is performed from immediately below the fire detector D as shown in FIG. L can be visually recognized directly.

  Next, the configuration of the heating tester 1, particularly the configuration of the main body 2 and the hood 3, will be described in detail.

  The main body 2 has a substantially rectangular parallelepiped shape, and contains an operating means for operating the fire detector D inside. On both long side walls 2a and 2b, shaft attachment portions 4c and 4d are provided above the center of gravity of the heating tester 1, and both arm portions 4a and 4b of the substantially U-shaped bracket 4 are attached to the shaft attachment portions 4c. , 4d. The main body 2 is pivotally supported by the bracket 4 so as to be rotatable around an axis along the short side direction. In the bracket 4, reference numeral 4e denotes a connection portion with the support rod 5, and the distal end of the support rod 5 is detachably connected to the connection portion 4e (see FIGS. 1 and 2).

  The hood 3 has a substantially cylindrical shape with a bottom and an open upper end, and is provided at the top of the main body 2 as described above. In an operation test, the upper end is brought into contact with the ceiling surface C, The fire detector D is located inside a substantially cylindrical tubular portion 3a having the bottom 3b, and the surroundings can be covered (see FIGS. 1 and 2). Here, in the case of the present embodiment, the cylindrical portion 3a and the bottom portion 3b are separately formed, and both are joined. Specifically, the lower opening edge of the cylindrical portion 3a is fitted into a concave groove provided on the outer peripheral edge of the bottom portion 3b, and thereby the two are joined (see FIGS. 6 and 7). The formation of the hood 3 is not limited to this, and for example, both may be formed by integral molding. Reference numeral 3c denotes a hood cover covering the entire upper opening edge of the cylindrical portion 3a. Specifically, similarly to the bottom portion 3b, it is formed separately from the cylindrical portion 3a, and the upper opening edge of the cylindrical portion 3a is fitted into a concave groove provided on the outer peripheral edge, thereby being joined to the cylindrical portion 3a. (See FIGS. 6 and 7). The formation of the hood cover 3c is not limited to this, and may be formed by integral molding with the cylindrical portion 3a, similarly to the bottom 3b.

  In the present embodiment, the heating tester 1 has the bottom 3b of the hood 3 formed of a translucent member (a transparent or translucent member). Specifically, the entire bottom 3b is formed as a translucent member. In addition, a non-protruding portion that does not protrude directly below the bottom 3b of the hood 3 is provided on a side portion of the main body 2, and the side of the non-protruding portion is positioned immediately below the translucent member 3b. A space S that does not obstruct the line of sight to the operation confirmation light L having the light emitting area is formed on the periphery of the fire detector D to be tested via the translucent member 3b. Specifically, the main body 2 has a substantially rectangular parallelepiped shape as described above, and a flat side surface portion parallel to a direction directly below the long side walls 2a and 2b is the non-projecting portion, and the side is A space S that is located immediately below the translucent member 3b and does not block the line of sight from the tester H directly below to the operation confirmation lamp L via the translucent member 3b is formed (FIGS. 1 and 2). reference).

  Therefore, according to the heating tester 1, even from directly below the fire detector D, the tester H performs the test through the space S on the side of the non-projecting portion of the main body 2 and the translucent member 3 b. The operation confirmation light L of the fire detector D is visible. In other words, the tester H itself can recognize the operation of the fire detector D during the test, and can perform the operation test of the fire detector D alone (see FIGS. 1 and 2). Even when the operation confirmation light L is not located at the periphery of the fire detector D, the light emission area of the operation confirmation light L is the periphery of the fire detector D and corresponds to the position corresponding to the translucent member 3b. , Even if the tester H is directly below the fire detector, the emission of the operation confirmation light L can be visually recognized.

  The heating tester 1 has a substantially rectangular shape in which the main body 2 is projected directly below, and its short side is located inside the periphery of the bottom 3b of the hood 3. Specifically, the main body 2 has a substantially rectangular parallelepiped shape, and all four sides of the top are located inside the periphery of the bottom 3b of the hood 3 (see FIG. 4B). According to the heating tester 1, the space S formed on the side of the side walls 2a and 2b, which are the non-projecting portions of the main body 2, is not obstructed from the line of sight from the tester H directly below to the translucent member. While ensuring a sufficient size, the volume of the main body 2 can also be ensured with a sufficient size.

  Further, in the case of the present embodiment, a plurality of projections 3d, which protrude outward and are made of an elastic body (elastomer, for example), are provided on the outer periphery of the bottom 3b of the hood 3 (see FIGS. 4 and 5). These projections 3d can prevent the heating tester 1 from rolling. In addition, the projections 3d absorb the impact, and can prevent the impact from being applied to the inside of the heating tester 1.

  Specifically, the plurality of projections 3d project outwardly in a shape forming a corner at the tip, but the projection 3d may have a rounded tip. Further, it is assumed to be continuous in the circumferential direction so as to form a polygonal shape in plan view, and to form a shape in which four corners of a quadrangle are cut out in a substantially V shape in plan view (FIGS. 4 and 4). (See FIG. 5). In the present embodiment, the plurality of protrusions 3d have a hollow portion, and have a shape that is easily crushed by an external force and easily absorbs an impact.

  Further, the heating tester 1 is provided with a shock absorbing member 2c made of an elastic body also in the main body 2. The shock absorbing member 2c has a frame shape along the outer shape of the main body 2, and is provided at the bottom of the main body 2 (see FIG. 4B). The impact absorbing member 2c can also prevent an impact from being applied to the inside of the heating tester 1, and particularly can prevent an impact from being applied to the inside of the main body 2.

  Although the hood cover 3c is provided at the upper opening edge of the hood 3, the hood cover 3c may be made of an elastic body, and the hood cover 3c may be configured to absorb the impact.

  Here, regarding the material of the hood 3, at least a part of the bottom 3b that forms the space S immediately below may be made of a translucent member, but the entire bottom 3b is made of a translucent member. It may be. Further, the entire hood 3 including the cylindrical portion 3a, the hood cover 3c, and the protrusion 3d may be made of a light-transmitting member, so that the operation confirmation lamp can be visually recognized from a wide direction. It is preferable because it can be performed. Further, the bottom 3b may be formed as a translucent member and an elastic body together with the projection 3d. In that case, for example, it may be made of transparent or translucent silicone rubber. The food cover 3c can also be made of, for example, transparent or translucent silicone rubber. The tubular portion 3a can be made of, for example, a transparent or translucent plastic without using an elastic member.

  Next, the configuration of the heating tester 1, particularly the configuration of the heating unit 6 and the blowing unit 7, will be described in detail.

  The heating tester 1 includes a heating means 6 and a blowing means 7 inside the main body 2 as operating means of a heat detector type fire detector D.

  The heating means 6 includes a cylindrical outer cylinder 6a having both ends opened, an inner cylinder 6b which is housed inside the outer cylinder 6a at a distance from the outer cylinder 6a and has both ends opened, and an inner cylinder 6b. And a heating element 6c composed of a heating wire housed in 6b. In the heating means 6, an opening directed downward from the outer cylinder 6a is used as a feed port 6d (between the outer cylinder 6a and the inner cylinder 6b), and an upward opening is defined as an outlet 6f (the outer cylinder 6a and the inner cylinder 6b). Between). An opening directed downwards of the inner cylinder 6b is defined as an inlet 6e, and an opening directed upwards is defined as an outlet 6g (see FIG. 6B). Note that the heating means 6 is provided at the upper central portion of the main body 2. Further, a top opening 2d communicating with a bottom opening 3f provided on a bottom 3b of the hood 3 attached to the top of the main body 2 and communicating with the outlets 6f and 6g of the inner cylinder and the outer cylinder of the heating means 6 is provided. Have been. Thereby, the high temperature air blown from the outlets 6f and 6g of the heating means 6 (particularly the outlet 6g of the inner cylinder 6b) blows into the hood 3 through the top opening 2d of the main body 2 and the bottom opening 3f of the hood 3. It is supposed to be.

  The blower 7 blows the air sucked from the outside air inlet 2e to the inlets 6d and 6e of the heater 6 (see arrow A1 in FIG. 6b), and from the inlet 6e of the inner cylinder 6b to the outlet 6g. The air is blown so as to pass through the inner cylinder 6 (see the same arrow A2), and the air is blown from the inlet 6d of the outer cylinder 6a to the outlet 6f so as to pass between the outer cylinder 6a and the inner cylinder 6b. (See arrow A3).

  The heating means 6 and the blowing means 7 are provided as described above, and heat the fire detector D by applying high-temperature air that is heated by the heating element 6c and blows into the hood 3 from the inner cylinder 6b. On the other hand, by blowing air between the inner cylinder 6b and the outer cylinder 6a by the blower 7, the heat of the inner cylinder 6b is suppressed from being transmitted to the outer cylinder 6a, and the heat radiation from the outer cylinder 6a to the inside of the main body 2 is suppressed. It is designed to suppress.

  Therefore, according to this heating tester 1, since the fire detector D is heated by the high-temperature wind using the heating wire as a heat source, the operation test of the fire detector D is repeatedly performed at an arbitrary timing without using combustible materials. It can be carried out. Further, since heat radiation to the inside of the heating test device 1 is suppressed, the mounting density in the main body 2 can be increased, and the heating test device 1 can be downsized. Furthermore, even if the heating output is increased, for example, even if the heating output is increased to such an extent that the fire temperature of the compensation rate system whose operating temperature is 150 ° C. can be operated, heat damage in the main body 2 can be prevented, It is possible to prevent the heating tester 1 from being damaged by heat.

  Further, in the present embodiment, the heating element 6c has a winding portion of the heating element 6c that is wound while being separated in the blowing direction of the blowing means 7 and generates a substantially annular heating region R (see FIG. 5). ing.

  As a result, the air blown from the blowing means 7 to the inlet 6e of the inner cylinder 6b passes through the inner peripheral side R 'and the outer peripheral side R' 'of the substantially annular heating zone R, and the air outlet of the inner cylinder 6b. 6 g is blown into the hood 3 as high-temperature air having an annular high-temperature distribution area to heat the fire detector D, so that it is possible to prevent the heating from being concentrated at one point, and to burn the fire detector D. Can be prevented.

  Further, in the case of the present embodiment, the blower 7 is provided inside the main body 2 in a direction along the side wall 2a of the main body 2 and is located on the side of the heating means 6, and as an example of a centrifugal fan that can be formed to be thinner, It is a turbo fan. Further, the blower means 7 as the centrifugal fan has an outlet 7c for blowing the air sucked from the intake port 7a downward, and the air blown from the outlet 7c is provided in a ventilation passage 8 provided below. (See arrow A1 in Fig. 6b).

  Thus, the thickness of the main body 2 can be reduced by forming the blower 7 to be thinner while being positioned on the side of the heater 6. Further, since the heating means 6 and the blowing means 7 are concentrated on the upper part of the main body 2, a space can be secured below them, and the space can be used as a mounting space for other parts and members. . For example, as will be described in detail later, it can be used as a storage space for the battery power supply 12 that drives the heating means 6 and the blowing means 7 and the like.

  The blowing means 7 sucks air inside the main body 2 as an air inlet in addition to the first air inlet 7a which sucks external air through an outside air inlet 2e provided on the side wall 2a of the main body 2. The second intake port 7b may be provided.

  Thereby, the air inside the main body 2 can be discharged to the outside via the heating means 6, preventing heat from accumulating inside the main body 2, thereby also preventing heat damage inside the main body 2. it can. Eventually, the air blowing means 7 attached to the side wall 2a of the main body 2 can be provided close to the side of the heating means 6 when it is positioned beside the heating means 6, and the thickness of the main body 2 can be reduced.

  Here, in the present embodiment, the blower means 7 specifically includes a fin that blows air in the centrifugal direction in a thin box-shaped fan case 7 d, and one side surface of the fan case 7 d It is provided so as to be close to or in contact with the side wall 2a. Further, when the first intake port 7a is provided on one side surface of the fan case 7d so as to open toward the outside air introduction port 2e, and when the second intake port 7b is provided, the fan case 7d has The other side surface is provided so as to open toward the heating means 6 side, and the exhaust port 7c is provided at the bottom surface so as to open toward the inlet 8a side which is one end opening of the ventilation passage 8. Have been. As described above, in the present embodiment, a turbo fan is used as a centrifugal fan that can be formed to have a small thickness. However, the present invention is not limited to this, and other centrifugal fans, such as a sirocco fan, blow air in various centrifugal directions. A blower can be used.

  In addition, the ventilation path 8 is specifically provided such that the inlet 8a, which is one end opening, opens toward the exhaust port 7c side of the blowing means 7. In addition, the inlet 8 a of the ventilation passage 8 may be provided so as to contact and communicate with the exhaust port 7 c of the blowing means 7. An outlet 8b, which is the other end opening of the ventilation passage 8, is provided so as to open toward both the inlets 6d and 6e of the heating means 6. Further, the ventilation path 8 is provided so as to form a substantially U-shaped flow path as a whole, and a first deflecting unit that changes the wind direction from below to the side in the flow path. 8c, and a second deflecting unit 8d that changes from a side to an upward direction. Each of the deflecting portions 8c and 8d is formed as a curved surface so as to reduce air resistance. The outlet 8b may be provided with a rectifying means such as a net so that the air blowing to the heating means 6 is equalized.

  As described above, the heating means 6 has the inner cylinder 6b made of a heat-resistant material, but the inner cylinder 6b can be specifically made of, for example, ceramics or pottery. Further, as described above, the outer cylinder 6a in which the inner cylinder 6b is accommodated has the outer cylinder 6a, and air is caused to flow between the outer cylinder 6a and the inner cylinder 6b. An air flow for heat insulation is generated, and heat radiation from the outer cylinder 6a to the inside of the main body 2 is suppressed. The outer cylinder 6a can be made of, for example, a metal material such as stainless steel, but may be made of a resin material having high heat resistance, or may be made of a heat insulating material. By forming the outer cylinder 6a from a heat insulating material, heat radiation from the inner cylinder 6b can be further blocked by the outer cylinder 6a, and heat radiation from the outer cylinder 6a to the inside of the main body 2 can be further suppressed.

  In the heating means 6, the heating element 6c has a winding portion for generating a substantially annular heating region R as described above. In the case of the present embodiment, the winding portion is disposed apart from the inner wall of the inner cylinder 6b and is wound in a coil shape. It may be wound in another mode, but by being wound in a coil shape, processing is easy, and the winding portion for generating the substantially annular heating region R as described above is used. Can be easily obtained.

  Further, the heating tester 1 includes a printed circuit board 9 for controlling the heating means 6 and the blowing means 7 inside the main body 2. As described above, by blowing air also between the outer cylinder 6a and the inner cylinder 6b, heat radiation from the outer cylinder 6a can be suppressed, and the air inside the main body 2 is sucked by the blowing means 7. This can prevent heat from accumulating inside the main body 2. Therefore, even if the heating means 6 is provided inside the main body 2 as in the heating tester 1, heat damage to the printed circuit board 9 provided inside the main body 2 can be prevented.

  For this reason, the printed circuit board 9 can be provided on the side opposite to the blowing means 7 with the heating means 6 interposed therebetween. That is, since the air blowing means 7, the heating means 6, and the printed circuit board 9 are arranged side by side in the short side direction of the main body 2 and concentrated on the space on the top side, a large space is provided below the inside of the main body 2. Can be secured. The lower space can be used as a storage space for various components, for example, the battery power supply 12 or the like.

  Further, as described above, since the heating tester 1 can prevent heat damage to components inside the main body 2, even if the battery power supply 12 and the like are stored inside the main body 2, the heat Harm can be prevented. The printed circuit board 9 is provided on the side wall 2b opposite to the side on which the blowing means 7 is provided, with the heating means 6 preferably disposed at the center for heating the fire detector D interposed therebetween. Alternatively, they are provided close to each other along the side wall 2b. This also allows the thickness of the main body 2 to be reduced.

  Further, the heating tester 1 is provided with a proximity sensor 10 on the top of the main body 2, and when the distance from the fire detector D becomes equal to or less than a predetermined value, electricity is supplied to the heating element 6c of the heating means 6 to start the test. In other cases, the test may not be conducted and the test may not be started.

  Thus, it is possible to prevent the heating tester 1 from being energized more than necessary before approaching the fire detector D to be tested, and furthermore, it is possible to make the battery power source last longer and repeat the test. The reason why the proximity sensor 10 is provided is that, as described above, heat damage to components inside the main body 2 can be prevented. In this embodiment, the proximity sensor 10 is provided on the side of the heating means 6 (side of the long side of the main body 2), and the sensor opening formed on the top of the main body 2. The sensor section is exposed from the window 2j toward the center of the top of the hood 3.

  Further, the heating tester 1 is provided with an indicator light 11 for displaying the operation status. The indicator light 11, together with the main power switch 13 and the operation switch 14, is provided on the side surface of the side wall 2b on the side where the printed circuit board 9 is provided inside. Thus, the printed circuit board 9 requiring connection and the like, the indicator light 11, the main power switch 13, the operation switch 14, and the like can be provided close to each other, and can be integrated with the printed circuit board 9.

  Further, although not shown in the drawing, an output varying means for varying the output of electric power from the battery power source 12 for driving the heating element 6c of the heating means 6 may be further provided. By providing such an output variable means and changing the magnitude of the output or the rate of increase of the output according to the operating temperature of the fire detector D to be tested, the fire detector D can be used for high-temperature operation, for example, when the operating temperature is 150 ° C. It is possible to provide an operable output even with the compensation rate type constant temperature sensor of the above.

  In addition, the indicator lamp 11 is provided in such a manner that the tester H can grasp the operating state of the proximity sensor 10 and the output state of the output varying means according to each operating state of the heating tester 1. Can be displayed. As a result, the tester H can properly understand whether or not the test is being performed, the output setting status, and the like, and can prevent an operation error and can prevent the fire detector from being damaged by burning.

  Next, the configuration of the heating tester 1, particularly, the battery power supply 12 inside the main body 2 will be described in detail.

  The heating tester 1 includes a heating unit 6 and an air blowing unit 7 and a battery power supply 12 for supplying electric power for driving them, as an operating unit of the heat-sensitive fire detector D, inside the main body 2.

  Thus, since the fire detector D is heated by the high-temperature wind using the heating element 6c as a heating wire as a heat source, the operation test of the fire detector D can be repeatedly performed at an arbitrary timing without using combustible materials. it can. Further, since the electric wire for supplying electric power is not exposed between the bracket 4 which supports the main body 2 from the outside and the inside of the main body 2, even if there is an obstacle around the fire detector D, the obstacle is not affected. The wires will not get caught.

  Therefore, according to the heating tester 1, the operation test of the fire detector D can be repeatedly performed at an arbitrary timing without using a combustible material, and an electric wire is connected to an obstacle around the fire detector D. It can be prevented from getting caught.

  Further, in the case of the present embodiment, as described above, the blowing means 7 is provided on the side of the heating means 6 inside the main body 2. Further, a printed circuit board 9 is provided. The heating means 6, the air blowing means 7 and the printed circuit board 9 provided side by side with them, and the ventilation path which is located below the heating means 6 and the air blowing means 7 and communicates the air blowing means 7 and the heating means 6. A battery power supply 12 is housed below the battery power supply 8.
