Description

  The present invention relates to a display device for a fire alarm, and more particularly to a display device that can clearly show the performance of a fire alarm.

  2. Description of the Related Art Conventionally, fire alarms that notify the occurrence of a fire have been installed in buildings such as houses, offices, or public facilities. For example, a fire alarm is equipped with a sensor that detects smoke concentration. When the smoke concentration detected by the sensor exceeds a predetermined threshold, it is determined that a fire has occurred, and an alarm is output to extinguish the fire. And encourage evacuation.

  It is desirable for fire alarms to detect fires as soon as possible and to start fire fighting and evacuation as soon as possible.On the other hand, if the smoke concentration is set to be judged to be a fire with a low threshold, there are many false alarms. There is a problem.

  Therefore, the applicant of the present application is provided with a sensor that detects the carbon monoxide concentration, and when the carbon monoxide concentration shows an abnormal value, a fire alarm device that lowers the smoke concentration threshold that is judged to be a fire, and other When the smoke concentration of a fire alarm installed in a room or the like shows an abnormal value, a fire alarm has been proposed that lowers the smoke concentration threshold for determining a fire (Patent Document 1). According to this, if there are other abnormalities, it can be judged that there is a fire even if the smoke concentration is lower than normal, and an alarm can be output, so it is possible to detect the fire early and other abnormalities. If not, the occurrence of a fire is determined based on the normal smoke concentration, so that false alarms can be suppressed.

Further, as shown in FIG. 4, a separate room detection alarm device 12 is provided at the center of the back surface of the second display area 22. The separate room detection alarm device 12 has the same external shape as the high performance alarm device. Since the timing of outputting the fire alarm and the CO concentration alarm can be explained by the display alarm device 9 in the first exhibition area 21, the separate room detection alarm device 12 can always output the fire alarm and the CO concentration alarm. There is no need.

  As shown in FIG. 2, the second light source 13 is provided in the upper part of the second display area 22. The second light source 13 is a light source that illuminates the second display area 22. Note that the second light source 13 only needs to emit at least white light. As shown in FIGS. 1 and 4, the first display area 21 and the second display area 22 have a plurality of LEDs arranged at equal intervals so as to connect the display alarm device 9 and the separate room detection alarm device 12. The pseudo communication cable 14 is formed. The pseudo communication cable 14 simulates communication between the display alarm device 9 and the separate room detection alarm device 12 and the communication direction between the display alarm device 9 and the separate room detection alarm device 12. It is shown as an example. For example, as described later, when the separate room detection alarm device 12 indicates that information indicating that the smoke density is a value suspected of the occurrence of a fire has been transmitted to the display alarm device 9, the separate room detection alarm device is used. The LEDs are sequentially turned on and off from the device 12 toward the display alarm device 9.

  The comparison target display area 23 is an display area provided on the left side of the housing 3 in FIG. As shown in FIGS. 1 and 4, a comparison alarm device 15 is fixed at the center of the rear surface of the comparison target display area 23. The comparison alarm device 15 has the same external shape as the conventional fire alarm device, and outputs a fire alarm based on a signal received from the main control unit 8. The comparison alarm device 15 is provided with a light emitting unit 15b and a speaker 15a that blink when a fire alarm is output, and a microcomputer that can control the light emitting unit 15b and the speaker 15a is incorporated therein. As shown in FIGS. 2 and 4, the comparison target display area 23 is provided with the third light source 16 and the pseudo fire source 11b, respectively, but the first light source 10 and the pseudo fire source 11a of the first display area 21 are provided. Since it is the same structure as, description is abbreviate | omitted.

  As shown in FIGS. 1 and 2, the front plate 5 includes the first front plate 51 covering the opening 4 of the first display area 21 and the second front covering the opening 4 of the second display area 22 as described above. It is divided into a face plate 52 and a third front plate 53 that covers the opening 4 of the comparison target display area 23. These front plates 5 can be controlled in a transparent state and a four-stage cloudy state. Here, the “transparent state” in the present invention refers to a state where visible light is transmitted and the exhibition space 2 is visible. It should be noted that the present invention is not limited to complete transparency, and may be transparent so that each alarm device installed in each exhibition area can be sufficiently visually recognized. Further, the “white turbid state” in the present invention means a state in which a person who observes the display device 1 of the fire alarm device is white and turbid by causing diffuse reflection of visible light on the front plate 5 or emitting the front plate 5 itself. By visually recognizing, the state can be understood that pseudo smoke is generated. The “white turbidity” in the present invention means how much each alarm device can be visually recognized in the white turbid state, for example, a value that can be indicated by numerical values such as light transmittance, haze value, or turbidity. .

  The front plate 5 is formed by attaching a film capable of controlling the state of light diffusely reflecting and the state of transmitting light by energization on one surface of the acrylic plate. As such a film, for example, a functional liquid crystal film whose orientation can be changed by energization can be used. Further, for example, a white turbid state may be realized by irradiating an acrylic plate with white light from a direction different from a normal light source and causing irregular reflection.

  As shown in FIG. 3, the operation unit 6 operates a first operation unit 61 that artificially operates the states of the first display area 21 and the comparison target display area 23, and operates a state of the second display area 22 in a pseudo manner. The second operation unit 62 is divided. The first operation unit 61 includes a first smoke concentration input unit 63, a first CO concentration input unit 64, and a first reset input unit 65. The first smoke density input unit 63 is configured to be able to input four levels of pseudo smoke density of 2% / m, 5% / m, 7.5% / m, and 10% / m. Further, the first CO concentration input unit 64 is configured to be able to input two levels of pseudo CO concentrations of 30 ppm and 550 ppm. Since the pseudo smoke concentration and the pseudo CO concentration in the first display area 21 and the comparison target display area 23 are set to the same value, the comparison of the performance of the fire alarm is made credible. The simulated smoke concentration and the simulated CO concentration in the display area 21 and the comparison target display area 23 fluctuate at the same value in conjunction with the inputs of the input units 63, 64, 65 of the first operation unit 61.

  The second operation unit 62 is provided with a second smoke density input unit 66 and a second reset input unit 67. The second smoke density input unit 66 is configured to be able to input a pseudo smoke density of only 5% / m. The simulated smoke density in the second display area 22 varies in conjunction with the input of each input unit of the second operation unit 62.

  As shown in FIGS. 1 and 5, the display unit 7 is provided on the comparison target display area 23, and displays a comparison target house display area 7 a that displays the state of the comparison target display area 23, a first display area 21, and Provided on the second display area 22 is a main house display area 7b for displaying the states of the first display area 21 and the second display area 22. In the comparison target house display area 7a, a comparative smoke alarm concentration meter 71, a comparative smoke concentration meter 72, and a comparative CO concentration meter 73 are displayed as bar graph meters. Specifically, various values are displayed by sequentially lighting the segment elements that can emit light in a line from the left.

  The comparison smoke alarm concentration meter 71 is a meter that displays a fire detection threshold value of the comparison alarm device 15 that is a value at which a conventional fire alarm device detects the occurrence of a fire and outputs a fire alarm. The “condition different from the fire alarm condition” in the present invention corresponds to the fire detection threshold value of the comparison alarm device 15 in the present embodiment. The fire detection threshold value of the comparison alarm device 15 is always 10% / m in this embodiment. Therefore, the comparative smoke warning concentration meter 71 always displays 10% / m.

  The comparative smoke concentration meter 72 and the comparative CO concentration meter 73 display the pseudo smoke concentration and the pseudo CO concentration received by the first smoke concentration input unit 63 and the first CO concentration input unit 64 of the operation unit 6, respectively. is there. The comparative smoke concentration meter 72 can display 4 levels of 2% / m, 5% / m, 7.5% / m, and 10% / m, and the comparative CO concentration meter 73 is 30 ppm. And 550 ppm can be displayed.

  In the home display area 7 b, a first living room display area 7 c is formed on the first display area 21, and a second living room display area 7 d is formed on the second display area 22. In the first room display area 7c, a first smoke alarm concentration meter 74, a first smoke concentration meter 75, and a first CO concentration meter 76 are displayed as bar graph meters, respectively. In the second room display area 7d, a second smoke alarm concentration meter 77 and a second smoke concentration meter 78 are displayed as bar graph meters, respectively. These meters also display various values by sequentially lighting the segment elements that can emit light in a line from the left in the same manner as each meter in the comparison target house display area 7a.

  The first smoke alarm concentration meter 74 is a meter that displays a fire detection threshold value of the display alarm device 9 that is a value at which a high-performance alarm device detects a fire occurrence and outputs a fire alarm. The “predetermined fire detection threshold” in the present invention corresponds to the fire detection threshold of the display alarm device 9 in the present embodiment. As the fire detection threshold, a normal value and a low set value are set. The normal value is 10% / m, and the low set value is 7.5% / m. The fire detection threshold of the display alarm device 9 is 5 when the pseudo CO concentration at which the first CO concentration input unit 64 of the operation unit 6 receives input is 30 ppm or more, and when the second smoke concentration input unit 66 of the operation unit 6 is 5 ppm. When accepting the input of the pseudo smoke density of% / m, it is lowered to the low set value. Here, the “predetermined smoke concentration abnormal value” in the present invention is 5% / m in the present embodiment, and the “predetermined CO concentration abnormal value” is 30 ppm in the present embodiment.

  The first smoke concentration meter 75 and the first CO concentration meter 76 have the same configuration as that of the comparative smoke concentration meter 72 and the comparative CO concentration meter 73 and display the same contents, and thus description thereof is omitted. To do.

  The second smoke alarm concentration meter 77 is a meter that displays a fire detection threshold value of the separate room detection alarm device 12. Since the separate room detection alarm device 12 is an exhibit of the same high performance alarm device as the display alarm device 9 in this embodiment, the fire detection threshold of the separate room detection alarm device 12 is the fire detection value of the display alarm device 9. Similar to the threshold value, a normal value and a low set value are set, the normal value is 10% / m, and the low set value is 7.5% / m. The fire detection threshold of the separate room detection alarm device 12 is lowered to a low set value when the first smoke concentration input unit 63 of the operation unit 6 receives an input of a pseudo smoke concentration of 5% / m or more.

  The second smoke density meter 78 displays the pseudo smoke density received by the second smoke density input unit 66 of the operation unit 6, and the second smoke density input unit 66 accepts only the pseudo smoke density of 5% / m. Therefore, the second smoke density meter 78 is in a state where all the segment elements of the meter indicating that the pseudo smoke density in the second display area is 0% / m and the pseudo smoke density is 5% / m. One of the states indicating that is displayed.

  As shown in FIG. 2, the main control unit 8, based on the input from the operation unit 6, fires the front panel 5, each alarm device 9, 12, 15, each light source 10, 13, 16, the display unit 7, etc. The state of each part of the display device 1 of the alarm device is controlled. The main control unit 8 is, for example, an MPU (Micro Processing Unit), but is not limited thereto, and may be any configuration as long as the state of each unit can be controlled based on an input from the operation unit 6. There may be. In the present embodiment, the main control unit 8 is provided at a position connecting the operation unit 6 and each unit. However, the main control unit 8 is not limited to this. For example, the main control unit 8 is provided in each of the alarm devices 9, 12, and 15. In addition, a control device provided in each microcomputer and other units may cooperate to control the fire alarm display device 1.

  Next, an example of processing performed by the main control unit 8 when the operation unit 6 of the fire alarm display apparatus 1 configured as described above receives an input will be described with reference to FIGS. The operation unit 6 can be independently input with a first smoke concentration input unit 63, a first CO concentration input unit 64, a first reset input unit 65, a second smoke concentration input unit 66, and a second reset input unit 67. Yes, the pseudo smoke concentration and the pseudo CO concentration of the first display area 21 and the comparison target display area 23 can be input independently. Note that the sequential processing is in no particular order, and the order in which each determination is performed does not have to be in the order described in FIGS.

  First, in FIG. 6, the main control unit 8 determines whether or not there is an input to the first smoke density input unit 63 (S100). If it is determined that there is an input to the first smoke density input unit 63 (S100: YES), the first front plate 51 and the third front plate 53 are controlled to the white turbidity corresponding to the inputted pseudo smoke density (S101). That is, when the input value is 2% / m, the cloudiness is controlled to be low, and the higher the input value is 5% / m, 7.5% / m, 10% / m, the higher the turbidity is. Control to the cloudy state. As a result, when the first display area 21 and the comparison target display area 23 are viewed through the first front plate 51 and the third front plate 53, the visitor feels that the smoke density increases as the input value increases. Can be recognized.

  If the first front plate 51 and the third front plate 53 are controlled to be clouded, then the display of the first smoke density meter 75 and the comparative smoke density meter 72 of the display unit 7 is changed according to the input values (S102). ). Further, the simulated fire sources 11a and 11b simulating cigarettes are turned on (S103), and it is produced that a fire has occurred due to the fired cigarette as a fire source.

  Then, the control unit determines whether or not the pseudo smoke density input to the first smoke density input unit 63 is equal to or higher than the smoke density abnormal value (S104). The smoke density abnormal value is 5% / m in the present embodiment. Here, the abnormal smoke concentration value is a value lower than the fire detection threshold value, and is not a value by which it can be determined that a fire has occurred by this numerical value alone, but is a numerical value at which the occurrence of a fire is suspected.

  If it is determined that the pseudo smoke density input to the first smoke density input unit 63 is equal to or higher than the smoke density abnormal value (S104: YES), then the display of the second smoke alarm density meter 77 is changed (S105). Specifically, the display of the second smoke alarm concentration meter 77 is lowered from 10% / m to 7.5% / m. That is, since it is determined in S104 that the pseudo smoke density in the first display area 21 is abnormal, the fire detection threshold of the separate room detection alarm device 12 provided in the second display area 22 is lowered, so that an early fire is generated. It is shown to the visitors that it is in a state where it can detect the occurrence of fire and output a fire alarm.

  When the display of the second smoke alarm concentration meter 77 is changed (S105), the pseudo communication cable 14 is then turned on (S106). That is, the information that the display alarm device 9 in the first display area 21 has determined that the smoke concentration is an abnormal value has been transmitted to the separate room detection alarm device 12 in the second display area 22 to the visitor. Show. If it is determined in S104 that the pseudo smoke density input to the first smoke density input unit 63 is not equal to or higher than the smoke density abnormal value (S104: NO), the process proceeds to S107 as it is.

  Once the process of S106 is performed, it is next determined whether or not the pseudo smoke density input to the first smoke density input unit 63 is equal to or higher than the fire detection threshold of the display alarm device 9 (S107). Specifically, the determination is made by comparing the fire detection threshold value stored in the memory (not shown) of the main control unit 8 or the microcomputer of the display alarm device 9 with the input value of the pseudo smoke density. If it is determined that it is equal to or greater than the fire detection threshold (S107: YES), it is determined that a fire has occurred, and thus an alarm is output to the display alarm device 9 (S108). Specifically, the light emitting unit 9b of the display alarm device 9 blinks to indicate a fire alarm, and a buzzer or a sound for notifying that a fire has occurred is output from the speaker 9a. If it is determined in S107 that the fire detection threshold is not exceeded, the process proceeds to S109.

  Next, it is determined whether or not the pseudo smoke density input to the first smoke density input unit 63 is 10% / m or more (S109). 10% / m in this determination processing is the fire detection threshold value of the comparison alarm device 15. The fire detection threshold value of the comparative alarm device 15 is always 10% / m. If it is determined that the simulated smoke density is 10% / m or more (S109: YES), it is determined that a fire has occurred in the comparative alarm device 15, and therefore an alarm is output to the comparative alarm device 15 (S110). . Specifically, the light emitting unit 15b of the comparison alarm device 15 blinks to indicate a fire alarm, and a buzzer or a sound for notifying that a fire has occurred is output from the speaker 15a. In S109, when it is determined that the pseudo smoke density is not 10% / m or more (S109: NO), the process returns to the start and repeats the process from S100.

  If it returns to S100 and it is judged that there was no input in the 1st smoke density | concentration input part 63 (S100: NO), it will be judged next whether the 1st CO density | concentration input part 64 of the operation part 6 had an input (S111). . If it is determined that there is an input to the first CO concentration input unit 64 (S111: YES), a first CO concentration input process described later is performed (S200), and then the process returns to the start and the process is newly repeated from S100.

  If it is determined that there is no input to the first CO concentration input unit 64 (S111: NO), it is then determined whether there is an input to the second smoke concentration input unit 66 of the operation unit 6 (S112). If it is determined that there is an input to the second smoke density input unit 66 (S112: YES), a smoke density input process for the second display area 22 described later is performed (S300), and then the process returns to the start, and processes from S100 are newly performed. repeat.

  If it is determined that there is no input to the second smoke concentration input unit 66 (S112: NO), it is then determined whether there is an input to the first reset input unit 65 of the operation unit 6 (S113). If it is determined that there is an input from the first reset input unit 65 (S113: YES), the display alarm device 9, the simulated fire source 11a in the first display area 21, the comparison alarm device 15 in the comparison target display area 23, the simulated fire. The state of each part such as the original 11b, the first front plate 51, and the third front plate 53 is reset (S114), and then the process returns to the start and the process is newly repeated from S100.

  If it is determined that there is no input to the first reset input unit 65 (S113: NO), it is then determined whether there is an input to the second reset input unit 67 of the operation unit 6 (S115). If it is determined that there is an input from the second reset input unit 67 (S115: YES), the state of each part such as the display alarm device 9 and the second front plate 52 in the second display area 22 is reset (S116), and thereafter Returning to the start, the process is newly repeated from S100.

  Next, the first CO concentration input process will be described with reference to FIG. If it is determined in S111 of FIG. 6 that there is an input to the first CO concentration input unit 64 (S111: YES), the emission colors of the first light source 10 and the third light source 16 are changed (S201). Specifically, when 30 ppm is input to the first CO concentration input unit 64 as the pseudo CO concentration, the normal white light sources 10 and 16 are changed to a light yellow emission color, and the first CO concentration input unit 64 When 550 ppm is input as the pseudo CO concentration, the emission color is changed to yellow. Thereby, it is possible to make the visitor understand that the carbon monoxide is present in the first display area 21 and the comparison display area 23 in a pseudo manner at the respective concentrations. In addition, although actual carbon monoxide is colorless and transparent, it becomes visible to a visitor by showing in pseudo yellow.

  When the processing of S201 is completed, the display of the first CO concentration meter 76 and the comparison CO concentration meter 73 on the display unit 7 is then changed to the pseudo CO concentration received by the first CO concentration input unit 64 (S202). . Next, it is determined whether or not the pseudo CO concentration received by the first CO concentration input unit 64 is greater than or equal to the abnormal CO concentration value (S203). The abnormal CO concentration value is 30 ppm in the present embodiment. Here, the abnormal CO concentration value is a numerical value lower than the CO alarm reference value for outputting a CO concentration alarm, and this numerical value alone is not a value that is necessary to output a CO concentration alarm for promoting ventilation or evacuation. This is a numerical value for which a fire is suspected.

  If it is determined that the pseudo CO concentration received by the first CO concentration input unit 64 is greater than or equal to the abnormal CO concentration value (S203: YES), the fire detection threshold of the display alarm device 9 is lowered (S204). Specifically, the fire detection threshold value stored in the memory of the main control unit 8 or the microcomputer of the display alarm device 9 is lowered from the normal value to the low set value. Then, the display of the first smoke warning concentration meter 74 on the display unit 7 is changed from 10% / m to 7.5% / m (S205), and the process proceeds to S206. If it is determined in S203 that the input pseudo CO concentration is not greater than or equal to the CO concentration abnormal value (S203: NO), the process proceeds directly to S206.

  In S206, it is determined whether or not the pseudo CO concentration received by the first CO concentration input unit 64 is 30 ppm or more. If it is determined that it is 30 ppm or more (S206: YES), the value stored in the memory of the main control unit 8 is 2% / m or more as the pseudo smoke density of the first display area 21 and the comparison display area 23 It is determined whether or not (S207). If it is determined that the pseudo smoke density in the first display area 21 and the comparison target display area 23 is 2% / m or more (S207: YES), the display on the second smoke alarm density meter 77 is changed from 10% / m to 7.5. Change to% / m (S208). That is, when the pseudo CO concentration in the first display area 21 is 30 ppm or more and the pseudo smoke concentration is 2% / m or more, although it is not a concentration that outputs an alarm, a fire is suspected. The visitor is informed that the fire detection threshold of the separate room detection alarm device 12 has been changed from the normal value to the low set value.

  When the processing of S208 is completed, the pseudo communication cable 14 is then turned on (S209). That is, the information indicating that the smoke alarm and the CO concentration are higher than usual and the fire is suspected by the display alarm device 9 in the first display area 21 is transmitted to the separate room detection alarm device 12 in the second display area 22. It shows to the visitor that it did. When the process of S209 is completed, the process proceeds to S210.

  If it is determined in S206 that the simulated CO concentration is not 30 ppm or more (S206: NO), or if it is determined in S207 that the simulated smoke concentration is not 2% / m or more (S207: NO), the process directly proceeds to S210. Proceed.

  In S210, it is determined whether or not the pseudo CO concentration received by the first CO concentration input unit 64 is greater than or equal to the CO alarm reference value. The CO alarm reference value is 550 ppm in the present embodiment. If it is determined that the value is equal to or higher than the CO alarm reference value (S210: YES), a CO concentration alarm is output (S211), this process ends, the process returns to the start of FIG. 6, and the determination process is newly repeated from S100. Specifically, the light emitting unit 9b of the display alarm device 9 blinks to indicate a CO concentration alarm, and a buzzer or a sound for notifying that the CO concentration is high is output from the speaker 9a. In the present embodiment, the comparison alarm device 15 does not detect the CO concentration alarm, so it does not output the CO concentration alarm, but the comparison alarm device 15 can detect the CO concentration as a conventional alarm. When using a device, in the process of S211, a CO concentration alarm may be output from the speaker 15a and the light emitting unit 15b from the comparison alarm device. If it is determined in S210 that the value is not equal to or greater than the CO alarm reference value (S210: NO), the process returns to the start of FIG. 6 and the determination process is newly repeated from S100.

  Next, the smoke density input process of the second display area 22 will be described with reference to FIG. If it is determined in S112 of FIG. 6 that there is an input to the second smoke density input unit 66 (S112: YES), the second front plate 52 is controlled to be clouded (S301). Since the second smoke density input unit 66 can input only 5% / m, the second front plate 52 is controlled to the white turbidity when the pseudo smoke density is 5% / m. And the display of the 2nd smoke density meter 78 of the display part 7 is changed into 5% / m (S302). Next, it is determined whether or not the pseudo smoke density received by the second smoke density input unit 66 is equal to or higher than the smoke density abnormal value (S303). In the present embodiment, the abnormal smoke concentration value is 5% / m, and the input value is only 5% / m. Therefore, it is not necessary to actually make this determination. The pseudo smoke density received by 66 is equal to or higher than the smoke density abnormal value (S303: YES). Accordingly, this determination process may be omitted in practice, but in the present embodiment, this determination process is provided in order to easily explain the process of the main control unit 8.

  When the second smoke density input unit 66 determines that the pseudo smoke density received by the input is equal to or higher than the smoke density abnormal value (S303: YES), the fire detection threshold of the display alarm device 9 is then lowered (S304). ). Specifically, the fire detection threshold value stored in the memory of the main control unit 8 or the microcomputer of the display alarm device 9 is lowered from the normal value to the low set value. Then, the display of the first smoke alarm concentration meter 74 on the display unit 7 is changed from 10% / m to 7.5% / m (S305), and then the pseudo communication cable 14 is turned on (S306). That is, the fact that the separate room detection alarm device 12 in the second display area 22 has determined that the smoke concentration is a value suspected of the occurrence of a fire is transmitted to the display alarm device 9 in the first display area 21. , Show to visitors. When the process of S306 is completed, the process returns to the start of FIG. 6 and the determination process is newly repeated from S100. In S303, if the second smoke density input unit 66 determines that the pseudo smoke density accepted by the second smoke density is not equal to or higher than the smoke density abnormal value (S303: NO), the process returns to the start of FIG. repeat.

  As described above, according to the fire alarm display device 1 of the present embodiment, the first front plate 51 and the third front panel 51 correspond to the pseudo smoke density received by the first smoke density input unit 63 of the operation unit 6. Since the white turbidity of the face plate 53 is controlled and the white turbidity of the second front plate 52 is controlled in accordance with the pseudo smoke density received by the second smoke density input unit 66, the first display area 21 of the exhibition space 2 is controlled. The state where the comparison target display area 23 and the second display area 22 are filled with smoke can be shown in a pseudo manner. Further, the fire alarm display device 1 is configured such that when the first CO concentration input unit 64 of the operation unit 6 receives an input of the pseudo CO concentration, the first light source 10 and the comparison target display region 23 of the first display region 21. Since the emission color of the third light source 16 is changed from white to light yellow or yellow, it is possible to easily explain how the display space 2 is filled with carbon monoxide.

  Therefore, it is possible to indicate a state of being filled with smoke and carbon monoxide without being necessary for safety and ventilation, so that the timing at which the display alarm device 9 outputs a fire alarm or a CO concentration alarm is visually easy to understand. Can explain the performance of fire alarms in an easy-to-understand manner.

  In particular, since the fire detection threshold of the first display area 21 is lowered from 10% / m to 7.5% / m based on the pseudo CO concentration received by the first CO concentration input unit 64, there is an abnormality in the CO concentration. In such a case, it is possible to determine that a fire is detected even at a smoke concentration lower than normal, and a fire alarm can be output, so that it can be easily understood that a fire can be detected early.

  The fire alarm display device 1 of the present embodiment has a second display area 22 in which a separate room detection alarm 12 is installed in addition to the first display area 21 in which the display alarm 9 is installed. The first display area 21 and the second display area 22 are recognized as separate rooms in the same building by unifying the shape imitating the roof on the top surface of the casing 3 and the color scheme and pattern of the casing 3. Since the second smoke concentration input unit 66 reduces the fire detection threshold of the first display area 21 from 10% / m to 7.5% / m, based on the pseudo smoke concentration that the input accepts. Even if there is an abnormality in the smoke concentration in the second display area 22, it is easy to understand that a fire alarm can be output even if the smoke concentration is lower than normal, and a fire alarm can be output. Can be explained. Since the pseudo communication cable 14 is provided between the display alarm device 9 and the separate room detection alarm device 12, the display alarm device 9 and the separate room detection alarm device 12 communicate with each other to determine the value of the fire detection threshold value. It can be shown visually that it is controlled.

  The fire alarm display device 1 according to the present embodiment has a comparison display area 23 in which the comparison alarm 15 is installed in addition to the first display area 21 in which the display alarm 9 is installed. The first display area 21 and the comparison target display area 23 can be recognized as separate buildings by differentiating the shape of the roof on the top surface of the casing 3 and the color scheme or pattern of the casing 3. Since the fire detection threshold of the comparative alarm device is always 10% / m, the fire of the display alarm device 9 is based on the simulated smoke concentration in the second display area 22 and the simulated CO concentration in the first display area 21. Compared with the point where the value of the detection threshold is lowered, the display alarm device 9 which is a high-performance alarm device can detect the occurrence of a fire early without causing a false alarm compared to the conventional fire alarm device. It can be shown in an easy-to-understand manner.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  For example, the comparison display area 23 and the second display area 22 are not indispensable components, and if at least the first display area 21 and the first front plate 51 are provided, the performance of the fire alarm can be minimized to the minimum. It can be shown clearly.

  The fire alarm display device 1 according to the present invention can be suitably used, for example, in a facility that exhibits the technology of housing equipment.
