Description

The present invention relates to disaster prevention equipment.

Conventionally, there has been known a detector that is installed on a ceiling or the like to detect heat caused by a fire (see, for example, Patent Document 1). This detector is periodically tested, and is configured to output information about the test by illuminating an indicator light on the outer cover of the detector.

JP 2012-198757 A

However, the testing of the detector in Patent Document 1 was performed, for example, by applying heat to the detector using a cylindrical test jig that covered at least a portion of the detector. Therefore, while applying heat with at least a portion of the detector covered by the test jig, the indicator light of the detector becomes hidden by the test jig and cannot be seen, which may prevent the user from understanding information about the test while heat is being applied.

Therefore, there was room for improvement in terms of making it possible to grasp information about the test even when at least a portion of the detector is covered by the test jig.

The present invention was made in consideration of the above problems, and aims to provide a disaster prevention device that allows users to grasp information about the test even when at least a portion of the disaster prevention device is covered by a test device.

In order to solve the above-mentioned problems and achieve the object, the disaster prevention equipment described in claim 1 is a disaster prevention equipment to be installed in a monitored area, and comprises an outer cover, a light emitting means for emitting light to output at least information related to a test of the disaster prevention equipment, a light-conducting protective means attached to the outer cover and housing a detection element for detecting heat of the monitored area by a frame portion while exposing the detection element from the outer cover to the space of the monitored area through an opening, and a thin-walled portion that is a portion thinner than other portions of the outer cover , and the protective means comprises a spectroscopic portion for causing light from the light emitting means to enter the protective means and also to enter the thin -walled portion , and at least a portion of the thin-walled portion is exposed to the outside of a testing device when the protective means is covered with the testing device to test the disaster prevention equipment, and the light incident on the thin-walled portion is
It is visible from the outside of the test device.

A disaster prevention device according to a second aspect of the present invention is the disaster prevention device according to the first aspect, wherein the thin portion extends from the front side of the outer cover to the side side of the outer cover.

According to the disaster prevention device of the first aspect, for example, it is possible to allow information relating to a test to be grasped.

Below, an embodiment of the disaster prevention device according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiment.

[Basic Concept of the Embodiment]
First, a basic concept of the embodiment will be described. The embodiment generally relates to disaster prevention equipment.

"Disaster prevention equipment" refers to equipment used for disaster prevention, and is a concept that includes, for example, equipment that detects abnormalities in a monitored area, and examples of such equipment include heat detectors, fire detectors, gas detectors, and smoke detectors. In addition, "disaster prevention equipment" includes, for example, an outer cover and a display means.

A "monitored area" is an area that is the subject of monitoring by disaster prevention equipment, and specifically refers to a space with a certain extent, and is a concept that includes, for example, rooms in a building (e.g., room A on the first floor, room B on the first floor, etc.), corridors, stairs, etc. Furthermore, an "abnormality in a monitored area" is a state in which the state of the monitored area is different from normal, and specifically refers to a concept that includes the outbreak of a fire, a gas leak, etc.

An "outer cover" is, for example, something that covers at least a portion of the components of a disaster prevention device.

"Display means" refers to a means that outputs at least information related to the testing of disaster prevention equipment by emitting light, and is provided on the outer cover. Specifically, the concept includes an object or part where at least a part of the display surface of the display means is exposed to the outside of the testing device when at least a part of the outer cover is covered with the testing device to test the disaster prevention equipment.

The term "display means" refers to, for example, a concept that includes a part or a protrusion from the side of the cover, a concept that includes at least a part or a projection formed on the edge of the front of the outer cover, a concept that includes light guiding means, and a concept that includes thin sections. The term "display surface of the display means" refers to, for example, a surface of the display means that is exposed to the outside of the disaster prevention device, a surface that emits light, and a surface that is visible to the user.

The "light guiding means" is, for example, a means formed in the outer cover, and is a concept that includes an object or a portion that guides light from the light emitting means. The "thin portion" is, for example, a portion that is thinner than other portions of the outer cover, and is a concept that includes a portion onto which light from the light emitting means is irradiated, and also includes a portion that transmits part of the irradiated light. The "light emitting means" is, for example, a means that outputs light.

In the following embodiments, the case where the "disaster prevention device" is a heat detector is described. In particular, in embodiment 1, the case where the display means is a light guide means is described, and in embodiment 2, the case where the display means is a thin-walled portion is described.

[Specific Contents of the Embodiment]
Next, the specific contents of the embodiment will be described.

(Embodiment 1)
First, a description will be given of embodiment 1. In this embodiment, a case will be described in which the display means is a light guide means.

(Configuration - Sensor)
First, the configuration of the sensor according to the present embodiment will be described. FIG. 1 is a perspective view of the sensor according to the embodiment of the present invention, FIG. 2 is a plan view of the sensor, FIG. 3 is a side view of the sensor, and FIG. 4 is a cross-sectional view taken along the line A-A in FIG. 2. In each figure, the Z axis indicates the vertical direction, and the X and Y axes perpendicular to the Z axis indicate the horizontal direction. For example, the terms "front portion", "rear portion", and "side portion" will be described as terms that refer to parts of the sensor 100. Specifically, when the sensor 100 is installed on the mounting target 900, which is the ceiling surface, the side of the sensor 100 that is located on the floor surface side (the opposite side of the mounting target 900 with the sensor 100 as the reference) (the -Z direction in FIG. 3) is referred to as the "front portion", and the side of the sensor 100 that faces the mounting target 900, which is the ceiling surface (the +Z direction in FIG. 3) is referred to as the "rear portion". The peripheral surface of the sensor 100 that is connected to the "front portion" and the "rear portion" is referred to as the "side portion." The definitions of the "front portion,""rearportion," and "side portion" are the same in the second embodiment.

The detector 1 in each of Figures 1 to 4 is a disaster prevention device, specifically a heat detector that detects heat, and is attached to an attachment target 900, which is, for example, a ceiling surface, via an attachment part 101 (e.g., a so-called "detector base"; detailed structure not shown) of the detector 100 in Figure 3, and as an example, includes an outer cover 11, a protective part 12, a prevention part 13 in Figure 1, and a thermistor 14 and a light-emitting part 15 in Figure 4.

(Configuration - Sensor - Outer cover)
The outer cover 11 in Fig. 1 covers at least a part of the components of the sensor 100. The specific type and configuration of the outer cover 11 are arbitrary, but for example, as shown in Fig. 3, the outer cover 11 has a cylindrical portion with the same diameter even when it is away from the mounting portion 101 and a tapered portion with a smaller diameter as it is away from the mounting portion 101, has light-shielding properties except for portions where specifically noted, and has a light guide portion 111 and an operation hole 112 in Fig. 2. Note that "light-shielding properties" refers to the ability to block light, and is a concept that indicates, for example, the ability of the outer cover 11 to block light from the inside to the outside.

The light guide unit 111 is the display means and the light guide means described above. The specific type and configuration of the light guide unit 111 are arbitrary, but for example, it is formed in a part of the outer cover 11, is formed of any material to function as a light guide that guides light and emits light, is formed separately from the part of the outer cover 11 that has light blocking properties, and passes light from the inside to the outside of the outer cover 11. In addition, the light guide unit 111 is, for example, a display surface of the light guide unit 111 (a surface exposed to the outside of the sensor 100 shown in Figures 2 and 3) that extends from the front side of the outer cover 11 (-Z direction) to the side side of the outer cover 11 (+X direction or -X direction), and two light guide units are provided, and as shown in Figure 2, the display surface of the light guide unit 111 is linear when viewed from the front side of the outer cover 11, and is provided at a position corresponding to the position of the operation hole 112.

The operation hole 112 is an operating means for physically operating the detector 100. The specific type and configuration of the operation hole 112 are arbitrary, but for example, it is a hole into which a protrusion of a specified tool is inserted to rotate the outer cover 11 of the detector 100 relative to the mounting part 101.

(Configuration - Sensor - Protection part)
The protective section 12 in Fig. 1 is a detection element protection means. The "detection element protection means" is, for example, a device that houses and protects a thermistor 14, which is a detection element. The type and configuration are arbitrary, but for example, it is formed as a part of the outer cover 11 and is formed of any material to function as a light guide that guides light and emits light. The protective portion is formed separately from the light-shielding portion of the outer cover 11 and allows light to pass from the inside to the outside of the outer cover 11. 12 is for protecting, for example, the thermistor 14 in FIG. 4 and has a hollow portion for accommodating the thermistor 14. The thermistor 12 is disposed on the opposite side (−Z direction) of the mounting portion 101 from the outer cover 11. 1, and is provided at the center of the outer cover 11 in the direction in which the outer cover 11 spreads (in a direction parallel to the XY plane). It is formed integrally with the 4. The protective section 12 includes, for example, a frame section 121 and an opening section 122 shown in FIG. 1, and a spectroscopic section 123 shown in FIG.

The frame portion 121 is, for example, a portion that forms at least a part of the outer shape of the protective portion 12, and is also a portion that includes one circular member that forms the tip portion (-Z direction) of the detector 100, and six support members that support the circular member between the circular member and the outer cover 11.

The openings 122 are, for example, portions through which hot air flows in and out of the thermistor 14 provided in the hollow portion of the protective portion 12, and are provided in six portions separated by the six support members of the frame portion 121 described above.

The spectroscopic unit 123 is, for example, a part that refracts, disperses, or reflects the light output from the light-emitting unit 15, and is also a part that faces the light-emitting unit 15.

(Configuration - Sensor - Prevention part)
The prevention unit 13 in Fig. 1 is a prevention means for preventing a contact object from coming into contact with the thermistor 14 housed in the protection unit 12. The prevention unit 13 is an object to be prevented from being touched by the opening 122, and is a concept including, for example, a user's finger. The specific type and configuration of the prevention unit 13 are arbitrary, but for example, it may be a protrusion provided at the opening 122. be.

(Configuration - Sensor - Thermistor)
The thermistor 14 in Fig. 4 is a detection element. A "detection element" is, for example, a component for detecting a physical quantity of a detection target. The "physical quantity of a detection target" is, for example, a quantity that may occur or change due to an abnormality in the monitoring area, and is a concept that includes, for example, temperature due to heat or hot air currents. The specific type and configuration of this thermistor 14 are arbitrary, but, for example, it detects temperature due to heat or hot air currents, protrudes in a direction (Z-axis direction) perpendicular to the direction in which the outer cover 11 spreads, and is housed in the protective part 12.

(Configuration - Sensor - Light Emitting Unit)
The light emitting unit 15 in Fig. 4 is the light emitting means described above. The specific type and configuration of the light emitting unit 15 are arbitrary, but for example, the light emitting unit 15 causes the light guiding unit 111 and the protective unit 12 to emit light, and outputs light toward the spectroscopic unit 123, and can be configured using a light emitting diode or the like.

(Light Emitting)
Next, light emission by the thus configured sensor 100 will be described. The sensor 100 may emit light at any timing, for example, when outputting information related to a test of the sensor 100, or when the sensor 100 judges a fire based on the temperature of heat detected by the thermistor 14. The process by which the sensor 100 judges a fire can be the same as the conventional process, and therefore the description thereof will be omitted. Fig. 5 is a diagram illustrating the optical path in Fig. 4.

A control unit (not shown) of the sensor 100 in FIG. 5 outputs light from the light-emitting unit 15. In this case, the light from the light-emitting unit 15 is refracted, dispersed, or reflected by the spectroscopic unit 123, and is guided to the entire light-guiding unit 111 and protective unit 12 as shown in FIG. 5. Note that for ease of explanation, only the optical path of the light from the light-emitting unit 15 on the left side of the drawing is shown in FIG. 5, but in reality, light is also output from the light-emitting unit 15 on the right side of the drawing and is guided to the entire light-guiding unit 111 and protective unit 12. Then, the entire light-guiding unit 111 and protective unit 12 in FIG. 1 emit light.

(test)
Next, a test of the thus configured detector 100 will be described. The term "test" refers to testing the capabilities of the detector 100. The specific content of the test of the detector 100 is arbitrary, but for example, a test will be described in which a test is performed to see whether the detector 100 detects the applied heat when heat is applied to the detector 100 by simulating the occurrence of a fire using a test device described later. Here, the following description will be given assuming that the controller of the detector 100 is configured to obtain the temperature detection result of the thermistor 14, detect a fire when the obtained temperature is equal to or higher than a threshold value, and output information indicating that the detector 100 has detected a fire in the test by continuing to output red light from the light-emitting unit 15 in FIG. 4.

Figure 6 is a side view showing the test device and the detector, Figure 7 is a diagram showing a test jig for the cross-sectional view of Figure 4, and Figure 8 is a diagram showing a test adapter for the cross-sectional view of Figure 4. Note that in Figures 7 and 8, the test jig 81 and the test adapter 82 are shown with dashed lines for the sake of convenience. In Figures 7 and 8, a part of the detector 100 is provided in the hollow inside the test jig 81 and the test adapter 82 and is not actually visible, but is shown with solid lines for the sake of convenience. The detector 100 is tested using the test device 800 in Figure 6.

(Testing - Testing Equipment)
The test device 800 is a device used for testing the detector 100, and includes, for example, a handle portion and a test jig 81 as shown in FIG. 6, and optionally includes a test adapter 82 as shown in FIG.

(Testing - Testing equipment - Test fixtures)
The test jig 81 is the above-mentioned test device, specifically, it is provided at the tip of the rod-shaped handle of the test device 800, and is, for example, cylindrical with a hollow portion for accommodating at least a part of the detector 100 (e.g., the protective portion 12, etc.) therein and applying heat, and is made of metal. The size of this test jig 81 is arbitrary, but for example, as shown in Fig. 7, a case will be described where the outer diameter of the test jig 81 is larger than the outer diameter of the detector 100 and the inner diameter of the test jig 81 is smaller than the outer diameter of the detector 100.

(Test - Test Equipment - Test Adapters)
The test adapter 82 in Fig. 8 is the above-mentioned test device, specifically, it is detachably attachable to the tip side (+Z direction) of the test jig 81 in Fig. 6, and is used, for example, to convert the diameter to a smaller diameter than the test jig 81, and is, for example, cylindrical and made of metal, and has a hollow portion that is continuous with the hollow portion of the test jig 81 when attached. The size of this test adapter 82 is arbitrary, but for example, a case will be described in which the outer diameter of the test adapter 82 is smaller than the outer diameter of the sensor 100 as shown in Fig. 8.

(Exam - Specific Content)
Next, a case where a test is performed without using the test adapter 82 and a case where a test is performed with the test adapter 82 will be described.

First, when performing a test without using the test adapter 82, the test jig 81 is abutted against the detector 100 as shown in FIG. 7, and a part of the detector 100 (e.g., the protective section 12, etc.) is housed in the hollow section of the test jig 81, and heat is applied from the hollow section of the test jig 81. In this case, the control section of the detector 100 detects a fire and outputs red light from the light emitting section 15 in FIG. 4. Then, as described above, the red light is guided to the light guiding section 111 and the protective section 12, and the entire light guiding section 111 and the protective section 12 emit light. In this case, a part of the light guiding section 111 and the protective section 12 are hidden by the test jig 81 as shown in FIG. 7 and cannot be seen from the outside, but since the side section 111A, which is a part of the side section side of the outer cover 11 in the light guiding section 111, is exposed, the red light emitted from the side section 111A can be seen. This allows the user to visually recognize the red light emitted from the side portion 111A and grasp information about the test.

Next, when performing a test using the test adapter 82, the test adapter 82 is brought into contact with the sensor 100 from the front side as shown in Figure 8, and a part of the sensor 100 (e.g., the protective section 12, etc.) is housed in the hollow section of the test adapter 82, and heat is applied from the hollow section side of the test adapter 82. In this case, the control section of the sensor 100 detects the heat and outputs red light from the light emitting section 15 in Figure 4. Then, as described above, the red light is guided to the light guiding section 111 and the protective section 12, causing the entire light guiding section 111 and the protective section 12 to emit light. In this case, as shown in FIG. 8, a part of the light guide 111 and the protective part 12 are hidden by the test jig 81 and cannot be seen from the outside, but the side part 111A, which is a part of the side part of the outer cover 11 in the light guide 111, and the front edge part 111B, which is a part formed on the edge of the front part of the outer cover 11 in the light guide 111, are exposed, so the red light emitted from the side part 111A and the front edge part 111B can be seen. Therefore, the user can grasp information about the test by visually checking the red light emitted from the side part 111A and the front edge part 111B.

(Effects of the embodiment)
Thus, according to this embodiment, when at least a portion of the outer cover 11 is covered by the test jig 81 or the test adapter 82 in order to test the sensor 100, at least a portion of the display surface of the light-guiding section 111, which is the display means, is exposed to the outside of the test jig 81 or the test adapter 82. This makes it possible to make a portion of the light-guiding section 111 visible, for example, even when at least a portion of the sensor 100 is covered by the test jig 81 or the test adapter 82, thereby making it possible to grasp information regarding the test.

In addition, by including a side portion 111A formed on the side portion of the outer cover 11, the display means can be viewed from any direction relative to the detector 100, for example, making it possible to reliably grasp information related to the test.

In addition, since the display means includes a front edge portion 111B formed on the edge of the front portion of the outer cover 11, the display means can be seen, for example, from directly below the detector 100, making it possible to reliably grasp information about the test.

In addition, because the display means is part of the light guide section 111, it is possible to improve the degree of freedom in the installation position of the light emitting section 15, which is the light source for the display means, thereby improving the degree of freedom in the design of the sensor 100.

(Embodiment 2)
Next, a second embodiment will be described. In this embodiment, a case where the display means is a thin portion will be described. Note that each component of the second embodiment is the same as each component of the first embodiment with the same name, unless otherwise specified.

(Configuration - Sensor)
First, the configuration of the detector according to the present embodiment will be described. Fig. 9 is a perspective view of the detector according to the embodiment of the present invention, Fig. 10 is a plan view of the detector, Fig. 11 is a side view of the detector, and Fig. 12 is a cross-sectional view taken along the line B-B of Fig. 10. The detector 200 in each figure is a disaster prevention device, specifically a heat detector for detecting heat, which is attached to an attachment target 900, for example, a ceiling surface, via an attachment part 201 of the detector 200 in Fig. 11, and includes, for example, the outer cover 21, protective part 22, and prevention part 23 in Fig. 9, and the thermistor 24 and light emitting part 25 in Fig. 12.

(Configuration - Sensor - Outer cover)
The outer cover 21 in Fig. 9 covers at least a part of the components of the sensor 200. The specific type and configuration of the outer cover 21 are arbitrary, but for example, the outer cover 21 blocks all or a part of the light and includes the thin portion 211 in Fig. 10.

The thin-walled portion 211 is a display means, and is a portion of the outer cover 21 that is relatively thin compared to other portions. The specific type and configuration of the thin-walled portion 211 are arbitrary, but for example, it is a portion that is thin enough to transmit at least a portion of the irradiated light (i.e., a portion that is thin enough to block only a portion of the irradiated light), is a portion that is formed integrally with other portions of the outer cover 21, extends from the front side (-Z direction) of the outer cover 21 to the side side (+X direction or -X direction) of the outer cover 21, there are two of them, and has a linear shape when viewed from the front side of the outer cover 21 as shown in FIG. 10.

Note that "other parts of the outer cover 21" refers to parts of the outer cover 21, specifically, parts of the outer cover 21 other than the thin-walled part 211, for example, parts that are thick enough to block all of the irradiated light.

(Configuration - Sensor - Protection part)
The protective portion 22 in Fig. 9 is the above-mentioned detection element protection means. The specific type and configuration of the protective portion 22 are arbitrary, but for example, it is formed in a part of the outer cover 21. In addition, the light guide is made of any material to function as a light guide that guides light and emits light. The light guide is formed separately from the light-shielding portion of the outer cover 21. The protective portion 22 is for protecting the thermistor 24 in FIG. 12 and is a part of the frame portion 221 in FIG. 10. 12. The configurations of the frame unit 221, the opening 222, and the spectroscopic unit 223 are the same as those of the first embodiment. , the explanation of which will be omitted.

(Configuration: Sensor, Prevention Unit, Thermistor, Light Emitting Unit)
The configurations of the prevention unit 23 in FIG. 9, the thermistor 24 in FIG. 12, and the light-emitting unit 25 are similar to those of the same names in the first embodiment, and therefore description thereof will be omitted.

(Light Emitting)
Next, a description will be given of light emission by the thus configured sensor 200. FIG 13 is a diagram illustrating an example of the optical path in FIG 12.

A control unit (not shown) of the sensor 200 in FIG. 13 outputs light from the light-emitting unit 25. In this case, the light from the light-emitting unit 25 is refracted, dispersed, or reflected by the spectroscopic unit 223, and is irradiated to the entire thin section 211 and guided to the entire protective section 22 as shown in FIG. 13. Note that for ease of explanation, only the optical path of the light from the light-emitting unit 25 on the left side of the drawing is shown in FIG. 13, but in reality, light is also output from the light-emitting unit 25 on the right side of the drawing, irradiated to the entire thin section 211, and guided to the entire protective section 22. Then, the entire thin section 211 and protective section 22 in FIG. 10 emit light.

(test)
Next, a test of the thus configured sensor 200 will be described. Fig. 14 is a diagram illustrating a test jig for the cross-sectional view of Fig. 12, and Fig. 15 is a diagram illustrating a test adapter for the cross-sectional view of Fig. 12. Here, a case where a test is performed without using the test adapter 82 and a case where a test is performed with the test adapter 82 will be described.

First, when performing a test without using the test adapter 82, the test jig 81 is abutted against the detector 200 as shown in FIG. 14, and a part of the detector 200 (e.g., the protective part 22, etc.) is housed in the hollow part of the test jig 81, and heat is applied from the hollow part of the test jig 81. In this case, the control unit of the detector 200 detects a fire and outputs red light from the light emitting unit 25 in FIG. 13. Then, as described above, the red light is irradiated to the entire thin part 211 and is guided to the entire protective part 22, so that the entire thin part 211 and the protective part 22 emit light. In this case, a part of the thin part 211 and the protective part 22 are hidden by the test jig 81 as shown in FIG. 14 and cannot be seen from the outside, but since the side part 211A, which is a part of the side part side of the outer cover 21 in the thin part 211, is exposed, the red light emitted from the side part 211A can be seen. This allows the user to visually recognize the red light emitted from the side portion 211A and grasp information about the test.

Next, when performing a test using the test adapter 82, as shown in Figure 15, the test adapter 82 is abutted against the detector 200 and a part of the detector 200 (e.g., the protective section 22, etc.) is housed in the hollow section of the test adapter 82, and heat is applied from the hollow section side of the test adapter 82. In this case, the control section of the detector 200 detects a fire and outputs red light from the light-emitting section 25 in Figure 13. Then, as described above, the entire thin section 211 is irradiated and the light is guided to the entire protective section 22, causing the entire thin section 211 and protective section 22 to emit light. In this case, as shown in FIG. 15, a part of the thin portion 211 and the protective portion 22 are hidden by the test jig 81 and cannot be seen from the outside, but the side portion 211A, which is a part of the side portion of the outer cover 21 in the thin portion 211, and the front edge portion 211B, which is a part formed on the edge of the front portion of the outer cover 21 in the thin portion 211, are exposed, so the red light emitted from the side portion 211A and the front edge portion 211B can be seen. Therefore, the user can grasp information about the test by visually checking the red light emitted from the side portion 211A and the front edge portion 211B.

(Effects of the embodiment)
Thus, according to this embodiment, since the display means is part of the thin-walled portion 211, for example, it is not necessary to provide other components for emitting light, so that the number of parts can be reduced, and costs can be reduced.

[Modifications to the embodiment]
Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions described in the claims. Such modifications will be described below.

(About the problem to be solved and the effects of the invention)
First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and may vary depending on the implementation environment of the invention and the details of the configuration, and may solve only some of the problems described above or achieve only some of the effects described above.

(Regarding decentralization and integration)
In addition, the above-mentioned configuration is a functional concept, and does not necessarily have to be physically configured as shown in the drawings. In other words, the specific form of distribution or integration of each part is not limited to that shown in the drawings, and all or part of it can be functionally or physically distributed or integrated in any unit.

(Light guiding section and thin section)
In the first embodiment, as shown in Fig. 2, the light guide section 111 has a linear shape when viewed from the front side of the outer cover 11, but the present invention is not limited to this. For example, the light guide section 111 may have a curved shape (e.g., an S-shape overall) when viewed from the front side of the outer cover 11. Similarly, the thin-walled section 211 in Fig. 10 of the second embodiment may have a curved shape (e.g., an S-shape overall).

In addition, in each embodiment, the case where two light guides and two thin sections are provided has been described, but this is not limited to this. For example, the light guides and the thin sections may be omitted, or one each may be provided, or three or more each may be provided.

(Regarding protrusions)
Also, a protrusion may be provided on the detector of each embodiment, and the protrusion may be used as a display means. FIG. 16 is a plan view of the detector, and FIG. 17 is a diagram illustrating a test jig with respect to the CC cross-sectional view of FIG. 16. A specific implementation method of the protrusion is arbitrary, but for example, by extending the length in the X-axis direction in the light guide 111 of FIG. 2 of the first embodiment, the tip of the light guide 311 having the same configuration as the light guide 111 may be configured as a protrusion 311A as shown in FIG. 16. In the case of the detector 300 configured in this way, when a test jig 81 is provided as shown in FIG. 17, the protrusion 311A, which is a part of the light guide 311, is exposed from the test jig 81, so that when the protrusion 311A emits light due to light from the light emitting unit during testing, the user can visually recognize the light emission. When configured in this manner, the protrusion 311A, which is the display means, protrudes from the side portion of the outer cover of the detector 300, so that, for example, the protrusion 311A, which is the display means, can be reliably seen, making it possible to reliably grasp information regarding the test.

For example, in the case of the sensor 200 of the second embodiment, the outer cover 21 may have an outer shape with a protrusion similar to that of the sensor 300 of FIG. 16, and the protrusion may be made thin, so that the protrusion serves as a display means.

In addition, for example, an indicator light other than the light-guiding portion or the thin portion (for example, a conventional bullet-shaped indicator light, etc.) may be provided on the side of the sensor, and the indicator light etc. may be configured as a protruding portion serving as an indicator means.

(Features)
In addition, the configurations of the above-described embodiments and the features of the modified examples may be combined in any manner. For example, a thin portion may be provided on the outer cover 11 of the sensor 100 in Fig. 2 so that the thin portion emits light together with the light guide portion 111, or a light guide portion may be provided on the outer cover 11 of the sensor 200 in Fig. 10 so that the light guide portion emits light together with the thin portion 211.

The disaster prevention device of appendix 7 is the disaster prevention device described in any one of appendices 1 to 6, and the disaster prevention device is at least a heat detector.

(Effect of supplementary notes)
According to the disaster prevention equipment described in Appendix 1, when at least a portion of the outer cover is covered with testing equipment in order to test the disaster prevention equipment, at least a portion of the display surface of the display means is exposed to the outside of the testing equipment. This makes it possible to make the display means visible, for example, even when at least a portion of the disaster prevention equipment is covered with the testing equipment, thereby making it possible to grasp information regarding the test.

According to the disaster prevention device described in Appendix 2, the display means protrudes from the side portion of the outer cover, so that, for example, the display means can be reliably seen, and therefore information regarding the test can be reliably grasped.

According to the disaster prevention device described in Appendix 3, the display means is formed on the side portion of the outer cover, so that, for example, the display means can be seen from all directions relative to the disaster prevention device, making it possible to reliably grasp information regarding the test.

According to the disaster prevention device described in Appendix 4, the display means is formed on the edge of the front part of the outer cover, so that the display means can be seen, for example, from directly below the disaster prevention device, making it possible to reliably grasp information regarding the test.

According to the disaster prevention device described in Appendix 5, the display means is a light guide, which, for example, improves the freedom of the installation position of the light source (e.g., the light-emitting means) relative to the display means, thereby improving the freedom of design of the disaster prevention device.

In the disaster prevention device described in Appendix 6, the display means is a thin-walled portion, which means that, for example, it is not necessary to provide other components for emitting light, and this allows the number of parts to be reduced, which in turn makes it possible to reduce costs.

According to the disaster prevention equipment described in Appendix 7, since the disaster prevention equipment is at least a heat detector, it is possible to provide a heat detector that can obtain information about the test even when, for example, at least a portion of the disaster prevention equipment is covered by a test device.
