Description

  The present invention relates to a composite type alarm device, and more specifically, a composite type that detects an abnormal state of a plurality of detection objects at an installation location and displays an alarm so that the detection object in the abnormal state can be identified. It relates to alarm devices.

  Of the fires that occurred, most of them were house fires such as houses and apartment houses. And many of them are due to "delay of discovery" because of delay in noticing the fire. In addition, many of the deaths due to house fires are elderly, and the risk of the elderly being a fire victim is higher than that of younger people. Therefore, in order to prevent house fire, prevent death due to fire, and reduce damage, early detection of fire is the most important, so the spread of fire alarms to general houses is desired.

  The location of the fire alarm is determined according to its sensing performance. Those having a heat sensing function are installed in the vicinity of the center of the wall surface where the floor area of the installation site is approximately 30 square meters or less and the range from 15 cm to 50 cm below the ceiling surface. Those with smoke detection performance are installed near the center of the wall surface in the range from 15 cm to 50 cm below the ceiling. Those with flame detection performance are installed on the wall.

  In addition, city gas alarms for city gas, which is lighter than air such as city gas, provided in ordinary houses are within a horizontal distance of 8 centimeters from the gas appliance on the same wall or ceiling surface as the gas appliance. The lower end of the alarm is installed at a position within 30 cm from the ceiling.

  As described above, since the fire alarm and the city gas alarm are close to each other, a composite gas fire alarm in which the fire alarm and the city gas alarm are integrated has been provided. And this applicant has provided the gas fire alarm device with few false alarms by integrating a gas alarm device and a fire alarm device, and integrating and processing the signal of a gas sensor and a fire sensor (patent document 1). reference).

JP 2000-30165 A

  As described above, in the case of a composite type alarm device that realizes a plurality of types of alarm objects with a single unit, a plurality of lamps (light sources) corresponding to each display color are provided on the front surface of the apparatus body, and the display colors of the emitted lamps are displayed. The alarm target is recognized by the user or the like by a combination of display colors and a combination of display colors and voices.

  For example, when a lamp corresponding to three colors of green, yellow, and red is used, in the gas leak alarm method, the first stage flashes red, the second stage lights up with a red lamp, and an alarm is given by synthesized speech. In this way, the gas leak state is recognized. In the incomplete combustion alarm method, when the concentration is low, the yellow lamp blinks, and after a delay time, a warning is generated by a synthesized voice. When the concentration is high, the yellow lamp is lit, after a delay time, an alarm is generated by a synthesized voice. By doing so, the state of incomplete combustion is recognized. In the fire alarm system, after the red lamp blinks and accumulates, the red lamp is lit and a warning is generated by a synthesized voice to recognize the occurrence of the fire.

  Also, depending on the model, the gas leak alarm method is that the first stage uses a melody alarm to blink the green and yellow lamps alternately, and the second stage uses a red lamp, green lamp off, and synthesized voice. By making an alarm, the gas leak state is recognized. The alarm method for incomplete combustion is to turn on the yellow lamp immediately when the concentration is low, and give a warning by synthetic voice after 5 minutes. In order to recognize the state of incomplete combustion. The fire alarm system recognizes the occurrence of a fire by lighting a red lamp and giving an alarm using synthesized speech.

  In this way, in the case of a composite type alarm device, the alarm method varies depending on the model, and basically, since the alarm is rarely performed, it is difficult for the user to remember the alarm method. . Therefore, even if an alarm display is performed in response to the occurrence of an alarm state, it is difficult to determine the alarm state from the alarm display, and there is a tendency to make an alarm sound determination.

  In addition, it is possible to recognize the alarm target by combining the display color of the lamp and the alarm sound. However, if multiple alarm targets are detected at the same time, it is difficult to determine the alarm target from the display color of the lamp. The current situation is that it must be judged from the alarm sound. In particular, for a hearing-impaired person or the like, there is a problem that only a display pattern with different lighting / flashing is insufficient for instantaneously determining an alarm because the method of notifying the alarm is only an alarm display.

  Also, in recent years, in order to make the number of deaths due to house fire a phenomenon, the Fire Service Act has been amended to require the installation of residential fire alarms including composite alarms in newly built and existing detached houses. Therefore, an early solution of the above-described problem is desired.

  Therefore, in view of the above-described problems, the present invention provides a composite alarm device that can be noticed only by displaying an alarm and that can quickly recognize an abnormal state detection target and a countermeasure. It is an issue.

In order to solve the above problems, the composite alarm device according to claim 1 according to the present invention, as shown in the basic configuration diagram in FIG. A detection unit 13; a determination unit 11a1 for determining whether the state detected by the state detection unit 13 satisfies a predetermined abnormality determination condition; and a detection target provided corresponding to the detection target Display control means 11a2 for displaying a plurality of alarm display means 20 for alarming an abnormality of an object, and for displaying the alarm display means 20 corresponding to the detection object determined by the determination means 11a1 to satisfy an abnormality determination condition. In the composite alarm device that warns of abnormality of the plurality of detection objects by display of the alarm display means 20, each of the plurality of alarm display means 20 If, in order to show the display plate of the translucent that the adhesive member on the back side are provided with covers an opening formed in said casing of composite alarm, the sense target allocated to the light source And a pictogram display unit 21 provided on the surface of the display plate for displaying a pictogram for recognizing a method for dealing with an abnormality in the detected object or the detected object, and emitting light by light from the light source. The display control means 11a2 causes the light source to emit light when the plurality of abnormalities are detected, and causes the pictogram display units 21 corresponding to all of them to have different timings. It is a means to make it light-emit instantaneously and to display.

According to the composite alarm device of the present invention described in claim 1, the state detection means 13 detects a plurality of detection objects such as methane gas, carbon monoxide gas, and temperature at the installation location. When the determination unit 11a1 determines that the state satisfies the abnormality determination condition, the light source corresponding to the detection object determined to be in the abnormal state is emitted by the display control unit 11a2, and the light is displayed as a pictograph. The pictograph display unit 21 is displayed by the emitted light from the unit toward the user or the like. When a plurality of abnormalities are detected, the pictogram display units 21 corresponding to all of them are instantaneously emitted and displayed at different timings by the display control means 11a2, so that a plurality of pictograms are combined. An abnormality is detected in the detection object.

  As described above, according to the composite alarm device of the present invention described in claim 1, when an abnormal state of a detection target object is detected at the installation location in the apparatus main body, a pictograph of a pictograph display unit corresponding to the detection target object Since the pictograms for recognizing how to deal with the abnormality of the alarm object are displayed by the display, the alarm object in the abnormal state and the coping method can be recognized from the pictogram displayed by the pictogram display unit. Therefore, it is possible to reduce damage and further contribute to the improvement of safety at the installation location. Furthermore, if the pictogram display unit is formed so as to protrude from the surface of the apparatus main body so that the light emitted from the light source corresponding to the observation object is emitted toward the user or the like, for example, the composite alarm device If you have a gas leak detection function, the installation location will be near the ceiling surface, so the pictogram display part will be raised so that it faces downward, and if you have an LP gas leak detection function, Since the place is near the floor, if the pictogram display part is raised so that it faces upward, the visibility of the composite alarm can be improved, so the abnormality can be detected more reliably and quickly. The object can be recognized.

Also, if the light source is made to emit light instantaneously at different timings according to the detection of the abnormal state of the detection object, the pictogram display part that protrudes from the surface of the device body flashes at the time of alarm. Therefore, the user or the like can be visually recognized, so that the user or the like can be focused on the pictogram display unit, and the visibility at the time of alarm can be improved.

  Further, since the light emitted from the light source is diffused by the diffusing member and the pictogram display portion is displayed by the diffused light, the pictogram display portion can be efficiently emitted by the light emitted from the light source. The visibility at the time can be further improved. In addition, the amount of light attenuation in the air layer interposed between the light source and the pictogram display unit can be reduced by the diffusion member.

  As shown in FIG. 2, the composite alarm device 10 includes a housing 10a formed in a substantially box shape with synthetic resin or the like, and is provided on the back side of the housing 10a at an installation location corresponding to its sensing performance. It is fixed via a fixed member. The composite alarm device 10 is operated by electric power supplied from a power supply unit (not shown) including a commercial power supply.

  As shown in FIG. 3, the composite alarm device 10 includes a microprocessor (MPU) 11 that operates according to a predetermined program. As is well known, the MPU 11 includes a central processing unit (CPU) 11a that performs various processes and controls according to a predetermined program, a ROM 11b that is a read-only memory storing a program for the CPU 11a, and various data. And a RAM 11c, which is a readable / writable memory having an area necessary for processing operations of the CPU 11a.

  The combined alarm device 10 is further capable of holding various stored data even when the power supply from the power supply unit is cut off, and has an electrical erasing / removing area having various storage areas necessary for processing operations of the CPU 11a. A rewritable read-only EEPROM 12 is provided, and the MPU 11 is connected to be readable and writable.

  The EEPROM 12 instantaneously causes the light source to emit light, abnormality determination condition information indicating an abnormality determination condition for determining whether or not the state of the detection target at the installation location of the apparatus main body is normal, and mode information indicating the alarm mode. Various information such as timing information indicating timing and flash determination condition information indicating determination conditions for determining whether or not to perform a flash alarm is stored.

  The composite alarm device 10 further includes a fire detector 13a that detects the occurrence of a fire, a gas detector 13b that detects a gas leak, and a CO detector 13c that detects CO (carbon monoxide) generated by incomplete combustion. These detection units are connected to the MPU 11.

  In the best mode, the case where the state detection means in the claims is realized by the fire detection unit 13a, the gas detection unit 13b, and the CO detection unit 13c will be described, but the present invention is not limited to this. When the combined alarm device 10 is a gas leak combined alarm device, various forms can be adopted, such as realizing the state detecting means only by the gas detector 13.

  The fire detection unit 13a is, for example, a fire sensor suitable for a device such as a heat sensor or a smoke sensor, and the fire sensor is provided in a state of being exposed to the outside of the housing through a through hole formed in the front of the housing. The fire sensor is protected by a protective member provided around the through hole. And the fire detection part 13a outputs the status signal regarding the fire in an installation place to MPU11.

  The gas detector 13b is, for example, a gas sensor suitable for a device such as a semiconductor gas sensor or a catalytic combustion type gas sensor, and the concentration of gas flowing from a plurality of slits formed from the upper right part of the front to the side of the housing. Are detected, and a detection signal corresponding to the concentration is output to the MPU 11.

  The CO detection unit 13c uses, for example, a contact combustion type CO sensor, and detects the concentration of CO gas flowing in from the slit or the like, as in the gas detection unit 13b, and outputs a detection signal corresponding to the concentration. Output to MPU11.

  In the best mode, the case where the gas detection unit 13b and the CO detection unit 13c are realized by separate sensors will be described. However, the present invention is not limited to this, and various cases such as realization by a single sensor are possible. Different forms are possible. In that case, it is possible to cope with this by detecting gas and CO at different timings.

  The composite alarm device 10 further includes an alarm unit 16 that emits an alarm sound based on synthesized speech, and an alarm display unit 20 that displays an alarm. For example, the alarm unit 16 converts the audio information output by the MPU 11 into an audio signal and outputs the audio signal from the speaker to the outside of the apparatus.

  The alarm display unit 20 corresponds to the alarm display means in the claims, and includes a plurality of light sources such as a fire light source 17a, a CO light source 17b, a gas light source 17c, and a power source light 17d. For example, an LED, a bulb, a lamp or the like suitable for the device is used. In the best mode, as shown in FIG. 4, a red LED is used as the fire light source 17a and the gas light source 17c, a yellow LED is used as the CO light source 17b, and a green LED is used as the power source 17d. As shown in FIG.

  The alarm display unit 20 further includes a diffusion member 19 that diffuses the light emitted from each light source. The diffusion member 19 formed by a light guide member or the like includes a first lens 19a corresponding to the fire light source 17a, a second lens 19b corresponding to the CO light source 17b, and a first lens 19c corresponding to the gas light source 17c. A third lens 19c, and a fourth lens 19d corresponding to the power source 17d.

  The shapes of the first lens 19a to the third lens 19c are substantially the same, and only the fourth lens 19d is formed slightly smaller than them. Since the power source light source 17d is always lit when the composite alarm device 10 is energized, the user or the like is composited based on whether or not the fourth lens 19d shines green. The energization state of the type alarm device 10 can be recognized.

  As shown in FIG. 4, one end side of each lens facing the light source is formed such that the cross section in the width direction intersecting with the longitudinal direction of the lens is an arc, and the other end side is a flat surface. The diffusing member 19 includes a connecting member 19e that connects the first lens 19a to the fourth lens 19d on the other end side, and the connecting member 19e is formed in a flat plate shape whose outer shape is substantially rectangular. .

  Further, the housing 10a is formed with an opening 10b having a shape corresponding to the outer shape of the connecting member 19e, and the opening of the connecting member 19e so that the surface thereof is continuous with the surface of the housing 10a. 10b.

  The alarm display unit 20 further includes a display plate 20a that covers the diffusion member 19 fitted in the opening 10b and fixes the diffusion member 19 to the housing 10a. The display plate 20a is formed of a substantially rectangular base member using a translucent resin member or the like, and an adhesive member is provided on the back surface thereof.

  Pictograph display units 21a to 21d for displaying pictographs for indicating detection objects assigned to the respective light sources are provided at positions on the surface of the display plate 20a facing the other ends of the first lens 19a to the fourth lens 19d. The other surface portion is coated with a paint having the same color as that of the housing 10a, and the surface thereof is further subjected to graining.

  The pictograph display unit 21a uses a fire as a detection target, and is a pictograph of "flame" as shown in FIG. The pictograph display unit 21b uses CO gas as the detection target, and is a pictograph of “open a window and ventilate” as shown in FIG. 2 in order to recognize a countermeasure for incomplete combustion. . The pictogram display unit 21c uses methane gas as the inspection object, and is a pictograph of "tighten the gas plug" as shown in FIG. 2 in order to recognize a countermeasure when a gas leak occurs. The pictogram display unit 21d is a pictograph of the power source.

  In the best mode, the case where the display plate 20a includes a pictogram display unit 21d corresponding to the power source will be described. However, the present invention is not limited to this, and the pictogram display unit 21d is configured based on the configuration. It can also be set as the structure deleted.

  As for the formation of the pictogram display portions 21a to 21d on the display plate 20a, the surface of the display plate 20a is subjected to a graining process to easily change the intensity of the color of light emitted from the light source. Therefore, the pictogram display portions 21a to 21d can be displayed with the optimum display luminance by forming the surface of the display plate 20a with the roughness of the surface corresponding to the strength of the display color.

  Further, in the display plate 20a, only the pictogram portions of the pictogram display portions 21a to 21d can transmit the light diffused by the first lens 19a to the fourth lens 19d. A user or the like can make the user visually recognize that each pictogram is shining with the light emitted from the display units 21a to 21d.

  In the best mode, the case where the diffusing member 19 is fixed to the housing 10a by the display plate 20a will be described, but the present invention is not limited to this, and the diffusing member 19 is provided with a locking piece or the like. Various forms such as a form attached to the housing 10a can be adopted.

  Next, an example of the fire light source 17a, the CO light source 17b, the gas light source 17c, and the power source light source 17d will be described with reference to the circuit shown in FIG. In FIG. 5, the anode of the LED 171 is connected to the power source V, and the cathode is connected to one end of a resistor 172 that is a load resistor for normal luminance and a resistor 173 that is a load resistor for high luminance (flash). The other ends of the resistors 172 and 173 are connected to the collectors of the transistors 174 and 175. The emitters of the transistors 174 and 175 are grounded, and the bases are connected to the MPU 11 via resistors 176 and 177, respectively.

  When the MPU 11 causes the LED 171 to emit light with normal luminance, the base of the transistor 174 is turned on and the base of the transistor 175 is turned off. When the LED 171 emits light with high brightness instantaneously, the base of the transistor 175 is instantaneously turned on at a predetermined timing while the base of the transistor 174 is turned on. As a result, the LED 171 that emits light with normal luminance is caused to emit light with high luminance instantaneously, so that the user can visually recognize the LED 171 as if it is flashing.

  Next, an example of the mode state stored in the EEPROM 12 will be described with reference to the drawing of FIG. In the best mode, it is assumed that the composite alarm device 10 provides alarms for three types of fire, gas leak, and incomplete combustion (CO).

  As shown in FIG. 6, the composite alarm device 10 has four alarm modes of mode 1, mode 2, mode 3, and mode 4. And when mode 1 is fire and incomplete combustion occur simultaneously, mode 2 is fire and gas leak simultaneously, mode 3 is incomplete combustion and gas leak simultaneously, Mode 4 shows a case where all of fire, incomplete combustion, and gas leakage have occurred. In the best mode, the priority order is set to increase in the order of gas leakage, incomplete combustion, and fire. However, various modes such as setting the priority order for each mode can be used.

  The timing information includes timing data indicating the timing of light emission of the light source corresponding to fire, incomplete combustion, and gas leakage, and the timing information is provided so as to correspond to the single alarm target and the above-described mode. Yes. For example, timing information corresponding to mode 4 will be described with reference to a timing chart shown in FIG.

The timing information corresponding to mode 4 includes a delay time D from the reference time, a period T for causing the light source to emit light, and a power feeding time F for each of fire, incomplete combustion, and gas leakage. When the CPU 11a confirms the mode 4, in the mode 4, the fire delay time T is a delay time with respect to the time t0 when the mode 4 is confirmed. Feed only F. Further, since the incomplete combustion delay time D is the time t1 at which the fire light source 17a starts to emit light, the CO light source 17b supplies power for the period T from the time t2 for the power supply time F. Further, the delay time D of the gas leak, because it is time t2 and initiate the luminescence of CO for an optical source 17b, gas source 17c from the time t3 for each period T to feed only power supply time F. Therefore, light is instantaneously emitted in the order of the fire light source 17a, the CO light source 17c, and the gas light source 17c at different timings.

  In addition, since the basic concept is the same for the other alarm modes, only the number of alarm objects is different, description thereof will be omitted. In addition, about the setting value of delay time D, the period T, and the electric power feeding time F, it can be set as a different form, such as setting it as a different setting value for every detection object.

  Next, an example of an outline of processing executed by the CPU 11a of the composite alarm device 10 will be described with reference to the flowcharts of FIGS.

  In step S1, detection signals input from each of the fire detection unit 13a, gas detection unit 13b, and CO detection unit 13c are stored in the RAM 11c as detection information. In step S2 (determination means), each detection information is compared with predetermined abnormality determination condition information, and it is determined whether an abnormal state is detected based on the comparison result. If it is determined that an abnormal state has not been detected (N in S2), the process returns to step S1 and a series of processes are repeated. On the other hand, if it is determined that an abnormal state has been detected (Y in S2), the process proceeds to step S3.

  In step S3 (display control means), by turning on the transistor 174 corresponding to each light source of the alarm display unit 20 corresponding to the detection target that has detected the abnormal state, lighting at a predetermined normal voltage is requested, Thereafter, the process proceeds to step S4.

  In step S4, the detection information in the RAM 11c is compared with predetermined flash determination condition information, and it is determined whether or not a flash alarm is necessary based on the comparison result. If it is determined that the flash alarm is not necessary (N in S4), the process proceeds to step S7. On the other hand, if it is determined that the flash alarm is necessary (Y in S4), the process proceeds to step S5.

  In step 5, the alarm mode is determined based on the detection object determined to require the flash alarm, and is stored in the RAM 11c as alarm mode data. In step S6 (display control means), the alarm mode indicated by the alarm mode data in the RAM 11c and a plurality of light sources corresponding to the alarm mode are specified to activate the display control module, and then the process proceeds to step S7.

  The activated display control module turns on the transistor 175 for each period T based on the corresponding timing information in the EEPROM 12 during the power supply time F, so that a high voltage higher than the normal voltage is generated every period T. Are instantaneously applied to the light source 171, and the light source 171 emits light with high luminance. When a plurality of light sources are controlled, the light source 171 is caused to emit light with high brightness in the order and timing indicated by the timing information of the EEPROM 12 corresponding to the designated alarm mode.

  In step S7, as in step S1, the detection signal input from each detection unit is stored in the RAM 11c as new detection information. In step S8, the detection information and the flash determination condition information are compared, and based on the comparison result, it is determined whether or not there is a detection target that no longer requires a flash alarm. If it is determined that there is no object to be detected (N in S8), the process proceeds to step S12 shown in FIG. On the other hand, if it is determined that there is an unnecessary detection object (Y in S8), the process proceeds to step S9.

  In step S <b> 9, it is determined whether or not flash alarms for all detection objects are no longer necessary. If it is determined that all of them are not required (N in S9), the display control module is requested to stop the flash alarm of the detection target that no longer requires the flash alarm in step S10 (display control means). Thereafter, the process proceeds to step S12 shown in FIG. Then, the display control module stops the flash alarm of the light source corresponding to the requested detection target.

  If it is determined in step S9 that the flash alarm for all detection objects is no longer necessary (Y in S9), in step S11 (display control means), the display control module that is activated is requested to end. As a result, the flash warning display is terminated, and then the process proceeds to step S12 shown in FIG.

  In step S12 shown in FIG. 9, each detection information is compared with predetermined abnormality determination condition information, and it is determined whether or not the normal state is restored based on the comparison result. If it is determined that the normal state has not been restored (N in S12), the process returns to step S7, and a series of processes is repeated. When it is determined that the normal state has been restored (Y in S12), the process proceeds to step S13.

  In step S13 (display control means), by turning off the transistor 174 corresponding to each light source of the alarm display unit 20 corresponding to the detection target that is lit, it is requested to turn off each light source, and then the process proceeds to step S14. .

  In step S14, it is determined whether or not everything has been restored based on the comparison result. If it is determined that all have not been restored (N in S14), the process returns to step S7 shown in FIG. 8, and a series of processing is repeated. If it is determined that all have been restored (Y in S14), the process proceeds to step S15.

  In step S15, it is determined whether an end request has been received. If it is determined that the end request has not been received (N in S15), the process returns to step S1 shown in FIG. 8, and a series of processing is repeated. If it is determined that a termination request has been received (Y in S15), the process is terminated.

  As is apparent from the above description, in the best mode, the CPU 11a of the composite alarm device 10 functions as a determination unit and a display control unit described in the claims. However, the present invention is not limited to this, and various forms such as realizing the display control means as a driver circuit of the alarm display unit 20 can be adopted.

  Next, an example of the operation (action) of the composite alarm device 10 of the present invention described above will be described in the case where all abnormalities of fire, incomplete combustion, and gas leakage are detected.

  When the composite alarm device 10 detects an abnormality of a detection target based on detection signals input from the fire detection unit 13a, the gas detection unit 13b, and the CO detection unit 13c, an alarm display corresponding to the detection target is displayed. The corresponding light source of the unit 20 is turned on. For example, when an abnormality is detected in the detection signal from the gas detection unit 13b, the gas light source 17c is turned on. The light emitted from the gas light source 17c is diffused by the third lens 19c, and the user or the like visually recognizes the pictogram display unit 21c of the alarm display unit 20 by the diffused light. As a result, the user or the like can recognize from the pictograph of the pictograph display unit 21c that gas leaks and the gas plug needs to be tightened.

  Further, when the combined alarm device 10 recognizes that the gas leak condition has deteriorated without the user or the like noticing the alarm display by the pictogram 21c, it determines that the flash alarm is necessary and lights at a predetermined timing. The gas light source 17c is caused to emit light with high brightness. As a result, the lit pictogram display unit 21c is displayed as if it is periodically flashing, so that the alarm display unit can be noticed by the user or the like.

  Further, when the composite alarm device 10 detects abnormality of a plurality of detection objects based on detection signals input from the fire detection unit 13a, the gas detection unit 13b, and the CO detection unit 13c, the detection objects By turning on all the corresponding light sources of the alarm display unit 20 corresponding to, one or all of the pictogram display units 21a to 21c of the alarm display unit 20 are displayed. Thus, even if a plurality of pictogram display sections 21a to 21c are displayed, each display section is a pictogram, so that the user or the like can easily recognize the abnormality of the detection target based on the pictogram displayed. can do.

  As described above, when an abnormal state of the detection target at the installation location is detected in the apparatus main body, the abnormality of the alarm target is warned by the display by the pictograph of the pictograph display units 21a to 21c corresponding to the detection target. Thus, the displayed pictograph can cause the user or the like to quickly recognize the detection object in the abnormal state, thereby contributing to improvement in safety at the installation location. In particular, it can be expected that a person with hearing loss or the like visually recognizes the danger reliably and promptly by an alarm by pictograms. Further, if a plurality of detection objects are in an abnormal state, an alarm is issued by displaying the pictograms of the corresponding pictogram display units 21a to 21c. Therefore, depending on the alarm sound, what kind of detection target the alarm is for Without having to do so.

  In addition, since the pictogram display units 21a to 21c are configured to display pictograms for recognizing how to deal with the abnormality of the detection target, an abnormal state alarm is generated from the pictograms displayed by the pictogram display units 21a to 21c. Since the object and the coping method can be recognized, it is possible to reduce the damage and further contribute to the improvement of safety at the installation location.

  Furthermore, since the light source is made to emit light instantaneously at a predetermined timing in response to the detection of the abnormal state of the detection target, the user appears as if the pictogram display units 21a to 21c are flashing at the time of a section alarm. Therefore, the user or the like can be focused on the pictogram display units 21a to 21c, and the visibility at the time of alarm can be improved.

  In addition, since the light emitted instantaneously from the light source is diffused by the diffusing member 19, the flash effect of the light source can be emphasized, so that the visibility at the time of alarm can be further improved. The amount of light attenuation by the air layer interposed between the light source and the pictogram display portion can be reduced by the diffusion member.

  In the above-described best mode, the case where the diffusion member 19 (see FIG. 4) is used has been described. However, the present invention is not limited to this, and the diffusion member 19 is omitted. You can also. One example thereof will be described below with reference to the drawing of FIG. In addition, the same code | symbol is attached | subjected to the part which is the same as that of what was demonstrated by this best form, or the detailed description is abbreviate | omitted.

  As shown in FIG. 10, the difference from the configuration of this best mode is that the light source 17a for fire, the light source 17b for CO, the light source 17c for gas, and the light source 17d for power supply are changed from chip LEDs to discrete LEDs. The light shielding wall 10c which prevents the interference of each light source was formed in the housing | casing 10a. With such a configuration, the configuration can be simplified and the number of parts can be reduced.

  Further, the light shielding wall 10c prevents the pictogram display portions 21a to 21d that do not correspond to the light source from being emitted by the light of the light source 17a fire light source 17a, CO light source 17b, gas light source 17c, and power source light source 17d. Therefore, visibility can be further improved.

  Furthermore, as shown in FIG. 11, the composite alarm device 10 described above may have a configuration in which the pictogram display units 21a to 21d are raised. In this case, by embossing or the like, the display plate 20a is formed by raising the portions of the pictogram display portions 21a to 21d of the display plate 20a, and the display plate 20a is adhered to a predetermined portion of the housing (apparatus body) 10a. Thus, the pictogram display portions 21a to 21d can be raised from the surface of the housing 10a. In addition, about the shape of the pictogram display parts 21a-21d, the cross section of the protruding part can be made into various shapes, such as a substantially triangle and a substantially circular arc.

  In this way, the pictogram display units 21a to 21d are arranged in a housing (so that the light emitted from the fire light source 17a, the CO light source 17b, the gas light source 17c, and the power light source 17d is emitted toward the user or the like. Since the apparatus body 10) is formed so as to protrude from the surface of the apparatus 10a, for example, when the combined alarm device 10 has a gas leak detection function for city gas, the installation location is near the ceiling surface. If it has an LP gas leak detection function, the installation location will be in the vicinity of the floor surface, so if the pictogram display part is raised so that it faces upward Since the visibility of the composite alarm device 10 can be improved, an abnormal detection target can be recognized more reliably and quickly.

  Further, if the light source 17a, the light source 17a for fire, the light source 17b for CO, the light source 17c for gas, and the light source 17d for power supply are made to emit light instantaneously at a predetermined timing in response to detection of an abnormal state of the detection object. Since the pictogram display units 21a to 21d that are raised from the surface of the apparatus body can be visually recognized by the user or the like at the time of alarm, the user or the like can be focused on the pictograph display units 21a to 21d. Thus, the visibility at the time of alarm can be improved.

  Further, in the above-described best mode, the case where the alarm display means in the claims is realized by the alarm display unit 20 using a plurality of light sources has been described. However, the present invention is not limited to this, and an alarm display is provided. Various embodiments such as a place where the unit is realized by a liquid crystal display device or the like can be used. If the liquid crystal display device is used in this way, pictograms can be displayed as moving images (animations).
