Mode for Carrying Out the Invention

[0016] 1. Configuration FIG. 1 is a diagram showing the configuration of a display system according to an embodiment. The display system S is a system that monitors a certain space (hereinafter referred to as the "monitoring target space") and displays information regarding the monitoring target space. Terminal devices for detecting abnormalities are arranged in the monitoring target space. In this sense, it can be said that the display system S is a monitoring system that monitors whether there is an abnormality in the monitoring target space. The display system S is composed of a display device 10, a fire receiver 30, and a plurality of fire detectors 40-1, 40-2, ···, 40-n (hereinafter collectively referred to as the fire detector 40). The abnormality detected in this example is a fire, and the fire detector 40 is an example of a terminal device. The display device 10 and the fire receiver 30 are connected by wire. The fire receiver 30 and each fire detector 40 are connected by wire and communicate with each other.

[0017] The display system S is a system that displays status information of the fire detector 40 on the display device 10. Status information of the fire detector 40 is collected via the fire receiver 30 and notified on the display device 10. Status information is information indicating the status of the fire detector 40. The status of the fire detector 40 can be normal or abnormal. Abnormal status includes, for example, a state in which a fire has been detected and a state in which the fire detector 40 has malfunctioned. The details of the method for notifying status information can be arbitrarily set by the user. Hereinafter, this setting will be referred to as the "status change setting". The status change setting includes monitoring settings and non-monitoring settings. Monitoring settings are settings for how to notify the status of the fire detector. Non-monitoring settings are settings to enable or disable each of at least one notification method in the monitoring settings. Non-monitoring settings also relate to stopping notifications regarding status information. The display system S makes it easier to change the status change settings.

[0018] The fire detector 40 is a device that detects fire. The fire detector 40 detects fire by detecting radiant energy, heat, or smoke from flames. When the fire detector 40 detects a fire, it transmits status information indicating that a fire has been detected to the fire receiver 30.

[0019] The fire alarm receiver 30 receives status information from each fire detector 40, displays the received status information on its own screen, and transmits the status information to the display device 10. The fire alarm receiver 30 records the identification information of the fire detector 40 that detected the fire and the time when the fire detector 40 detected the fire, linking them together. The fire alarm receiver 30 also stores the addresses of the fire detectors 40 connected to it.

[0020] Figure 1 shows an example where one fire alarm receiver 30 is connected to one display device 10, but this connection relationship is not limited to one-to-one. For example, multiple fire alarm receivers 30 may be connected to one display device 10. In this case, the display device 10 can integrate and display information from multiple fire alarm receivers 30. The display device 10 has its own memory area for storing this information and can process information obtained from multiple fire alarm receivers 30 across all devices. For example, the display device 10 has functions to sort and display information from multiple connected fire alarm receivers 30 in chronological order, output historical data, and make it easier to refer to past history.

[0021] Figure 2 illustrates the functional configuration of the display system S. The display system S includes a display control means 201, a display means 202, a receiving means 203, a first storage means 204, a transmission means 205, a receiving means 206, a second storage means 207, an information transmission means 208, an information receiving means 209, a method determination means 210, a notification means 211, a time determination means 212, and a recovery means 213. The display control means 201, the display means 202, the receiving means 203, the first storage means 204, the information receiving means 209, the method determination means 210, the notification means 211, the time determination means 212, and the recovery means 213 are implemented in the display device 10. The receiving means 206, the second storage means 207, and the information transmission means 208 are implemented in the fire receiver 30. The transmission means 205 is implemented in the fire detector 40.

[0022] The functions of the display device 10 are described below. The first storage means 204 stores the unmonitored setting database 800. The display control means 201 controls the display means 202 to display various information. The display means 202 displays various information according to the control by the display control means 201. The receiving means 203 accepts, via user operation, the designation of the fire detector 40 to be set to unmonitored, the input of the unmonitored setting, and the input of the recovery time. The information receiving means 209 receives status information and information indicating the notification method from the fire receiver 30. The method determination means 210 re-determines the notification method for the status information by referring to the unmonitored setting database 800. The notification means 211 notifies the status information according to the notification method determined by the method determination means 210. The time determination means 212 determines that the current time has reached the recovery time. The recovery means 213 restores the unmonitored setting related to the status information to a monitored setting.

[0023] The functions of the fire alarm receiver 30 are described below. The second storage means 207 stores the monitoring setting database 1300. The receiving means 206 receives status information and the address of the fire alarm 40 from the fire alarm 40. The information transmitting means 208 transmits status information and information indicating the notification method to the display device 10.

[0024] The function of the fire detector 40 will be explained. The transmitting means 205 transmits status information along with its address to the fire receiver 30.

[0025] Figure 3 illustrates the hardware configuration of the display device 10. The display device 10 is a computer device comprising a CPU (Central Processing Unit) 101, memory 102, storage 103, communication interface (IF) 104, input unit 105, display 106, and speaker 107. The CPU 101 is a control device that executes programs, performs various calculations, and controls other hardware elements of the display device 10. The memory 102 is a main memory that functions as a work area when the CPU 101 executes programs. The storage 103 is a non-volatile auxiliary storage device that stores various programs and data. The communication interface 104 is a communication device that communicates with other devices according to a predetermined communication standard (e.g., Ethernet®). The input unit 105 is an operation unit consisting of a keyboard, mouse, or touch panel, which inputs various information according to user instructions. The display 106 is a flat panel display such as a liquid crystal display or an organic EL display, which outputs images or characters. The speaker 107 outputs sound.

[0026] In this example, storage 103 stores a program (hereinafter referred to as the "display device program") that causes the computer device to function as the display device 10 in the display system S. The CPU 101 executes the display device program, thereby implementing the functions shown in Figure 2 in the computer device. When the CPU 101 is executing the display device program, the CPU 101 is an example of the display control means 201, method determination means 210, notification means 211, time determination means 212, and recovery means 213; memory 102 or storage 103 is an example of the first storage means 204; communication IF 104 is an example of the information receiving means 209 and notification means 211; input unit 105 is an example of the reception means 203; display 106 is an example of the display means 202 and notification means 211; and speaker 107 is an example of the notification means 211.

[0027] Figure 4 illustrates the hardware configuration of the fire alarm receiver 30. The fire alarm receiver 30 is a computer device comprising a CPU (Central Processing Unit) 301, memory 302, storage 303, communication interface (IF) 304, display 305, input unit 306, and speaker 307. The CPU 301 is a control device that executes programs, performs various calculations, and controls other hardware elements of the fire alarm receiver 30. The memory 302 is a main memory that functions as a work area when the CPU 301 executes programs. The storage 303 is a non-volatile auxiliary memory that stores various programs and data. The communication interface 304 is a communication device that communicates with other devices according to a predetermined communication standard (e.g., Ethernet®). The display 305 is a flat panel display such as a liquid crystal display or an organic EL display, and outputs images or characters. The input unit 306 is an operation unit consisting of a keyboard, mouse, or touch panel, and inputs various information according to user instructions. The speaker 307 outputs sound.

[0028] In this example, storage 303 stores a program (hereinafter referred to as the "fire alarm receiver program") that causes the computer device to function as a fire alarm receiver 30 in the display system S. The CPU 301 executes the fire alarm receiver program, thereby implementing the functions shown in Figure 2 in the computer device. While the CPU 301 is executing the fire alarm receiver program, memory 302 or storage 303 is an example of the second storage means 207, and communication IF 304 is an example of the receiving means 206 and the information transmission means 208.

[0029] Although not shown in the diagram, the fire detector 40 includes, for example, a fire detection element, a fire detection circuit, a monitoring circuit, an indicator light, and a signal input / output unit. The fire detection element is a sensor element that senses physical phenomena associated with a fire. Physical phenomena associated with a fire include, for example, at least one of heat (temperature rise due to fire), smoke (smoke generated by fire), and flame (radiant energy of the fire). The fire detection circuit processes the signal output from the fire detection element and detects a fire. The monitoring circuit monitors whether a malfunction (or abnormality) has occurred in the fire detection element or the fire detection circuit, and outputs a signal indicating a malfunction if one occurs. The indicator light is a light-emitting element that indicates that the fire detector 40 has detected a fire or that a malfunction has occurred. The signal input / output unit outputs status information of the fire detector 40 to the fire receiver 30 as an answer to an inquiry from the fire receiver 30. This inquiry is repeated periodically. In this example, in addition to the occurrence of a fire, the fire detector 40 also notifies of a malfunction of the fire detector 40 itself as an abnormality through its status information. In other words, the status indicated by the status information is normal, fire has occurred, or a malfunction has occurred. The response of the fire detector 40 can be either by returning a measurement value from the sensor (i.e., the fire receiver 30 makes the determination of whether or not there is a fire), or by the fire detector 40 itself interpreting the measurement value from the sensor to determine whether or not there is a fire and returning the result. In this specification, both modes are expressed as "the fire detector detects a fire." These hardware elements are housed in a casing. The casing has a mounting structure or fittings for attaching the fire detector 40 to a structure (e.g., a ceiling or wall).

[0030] 2.Operation 2.2.1 Input of Unmonitored Settings Figure 5 is a flowchart illustrating the operation of the unmonitoring setting process in the display device 10. The process in Figure 5 is started by launching the display device program in the display device 10. In step S501, the display device 10 displays a map of the monitored space with image objects superimposed on the display 106.

[0031] Figure 6 is an example of a map 600 of the monitored space. For example, if the display device 10 is installed in an office building, the map 600 of the monitored space displayed on the display device 10 shows a floor plan of a certain floor in the office building. Image objects 601 are superimposed on the map 600 of the monitored space. The image objects 601 show the arrangement of fire detectors 40. The image objects 601 are positioned on the map 600 of the monitored space to correspond to the actual locations of the fire detectors 40 in the monitored space.

[0032] Refer to Figure 5 again. In step S502, the display device 10 accepts the designation of some of the fire detectors 40 to be set to unmonitored. Specifically, the display device 10 accepts the range designation of the monitored space on the map via the user's operation of the input unit 105 while the map 600 is displayed. More specifically, the user's drag operation on the map is accepted as the range designation.

[0033] Figure 7, following on from Figure 6, illustrates a map of the monitored space. Image object 701 is an image object corresponding to the fire detectors 40 included in the range 702 specified in step S502. Image object 601 and image object 701 differ in appearance, specifically in the color of the objects. Because image object 601, which shows an unspecified fire detector 40, and image object 701, which shows a specified fire detector 40, have different appearances, the user can visually distinguish between the specified fire detectors 40 and the unspecified fire detectors 40.

[0034] In step S502, when the fire detector 40 is specified, the unmonitoring setting screen 900 shown in Figure 9 is automatically displayed on the display device 10. In step S503, the display device 10 accepts input of the unmonitoring setting for the fire detector 40 specified in step S502. The unmonitoring setting is entered via the user's operation of the input unit 105 while the setting screen 900 (or input screen) is displayed. The display device 10 reads the unmonitoring setting database 800 and displays the setting screen 900, reflecting the information stored in the unmonitoring setting database 800 shown in Figure 8.

[0035] Figure 8 illustrates the unmonitoring settings database 800. The unmonitoring settings database 800 is stored in the display device 10. The unmonitoring settings database 800 is a database that stores unmonitoring settings related to the status information of the fire detectors 40. The unmonitoring settings database 800 has multiple records. Each record includes a set of detector ID 801 and detector status 802, as well as whether the setting is present or not 803 and the recovery time 804. The presence or absence of the setting and the recovery time are recorded for each of the multiple notification methods. The notification method is the method of notifying status information on the display device 10, for example, audible notification, display notification, or history recording. The unmonitoring setting is a setting to prevent the actions set in the monitoring setting from being performed. Detector ID 801 is an ID for uniquely identifying each of the fire detectors 40. Fire detector status 802 is the state of the fire detector 40 that reflects the information set in whether the setting is present or not 803. Fire detector status 802 can be, for example, normal, fire detected, or malfunction occurred. The setting status 803 indicates whether or not a setting for the notification method of status information is set. The setting status 803 is further divided into setting items for sound alarm 805, alarm display 806, and history record 807. Sound alarm 805 indicates whether or not the setting for notification by sound alarm is enabled or disabled. Alarm display 806 indicates whether or not the setting for notification by alarm display is enabled or disabled. History record 807 indicates whether or not the setting for recording the history of when the fire detector 40 detects a fire is enabled or disabled. Recovery time 804 is the time to restore the unmonitored setting to the monitored setting. Recovery time 804 is further divided into setting items for sound alarm 808, alarm display 809, and history record 810. Sound alarm 808 is the scheduled time to rewrite sound alarm 805 to "enabled" when "none" is stored in sound alarm 805. Alarm display 809 is the scheduled time to change alarm display 806 to "Yes" if "None" is currently stored in alarm display 806. History record 810 is the scheduled time to change history record 807 to "Yes" if "None" is currently stored in history record 807.For example, the first line of the unmonitored settings database 800 indicates that, until October 1, 2024, at 00:00:00 AM, fire detector 40 with detector ID "2" is configured not to emit an audible notification when it detects a fire (i.e., it is unmonitored). Also, the first line of the unmonitored settings database 800 indicates that, until October 1, 2024, at 00:00:00 AM, fire detector 40 with detector ID "2" is configured not to record a history when it detects a fire (i.e., it is unmonitored).

[0036] Regarding the history record 807, the fire alarm receiver 30 also records the history of when a fire is detected. However, as mentioned above, the display device 10 records the history in a memory area independent of the fire alarm receiver 30 and processes this history, so it is significant that the history recording can be turned on and off independently of the fire alarm receiver 30. For example, if the history of fire detection is recorded as is, alarms during inspections or construction (which are false alarms) and alarms during normal times (which represent actual abnormal situations) will be recorded without distinction, and when trying to analyze this history later, the alarms during inspections or construction will become noise. In addition, these histories will put a strain on the memory area. From this perspective, it is significant that the history record 807 can be set to not be monitored.

[0037] Figure 9 is an example of the settings screen 900. The settings screen 900 has multiple UI objects. Each UI object corresponds to a different setting item. Specifically, the settings screen has buttons 901 to 906. Button 901 is a UI object for disabling or enabling audible notification when a designated fire detector 40 detects a fire. Button 902 is a UI object for disabling or enabling alarm display notification when a designated fire detector 40 detects a fire. Button 903 is a UI object for disabling or enabling the recording of the history when a designated fire detector 40 detects a fire. The history includes the identification information of the fire detector 40 that detected the fire and the time when the fire detector 40 detected the fire. Button 904 is a UI object for disabling or enabling audible notification when a designated fire detector 40 malfunctions. Button 905 is a UI object for disabling or enabling alarm display notification when a designated fire detector 40 malfunctions. Button 906 is used to disable or enable the recording of the history of a malfunction in a designated fire detector 40. The history includes the identification information of the fire detector 40 that detected the malfunction and the time when the fire detector 40 detected the malfunction.

[0038] In this embodiment, disabling notifications by sound, disabling notifications by alarm display, and disabling history recording are all set to "unmonitored." On the settings screen 900, no unmonitored settings have been made yet. For example, when button 901 is selected, the screen display changes as shown on the settings screen 1000 in Figure 10.

[0039] Figure 10 is an example of the settings screen 1000. The settings screen 1000 shows that if a fire is detected in any of the fire detectors 40 specified in step S502, the display device 10 will not sound an alarm, but the display device 10 will display an alarm, and the fire detection history will be recorded in the fire receiver 30. It also shows that if a malfunction is detected in any of the specified fire detectors 40, the display device 10 will sound an alarm, the display device 10 will display an alarm, and the fire receiver 30 will record the history of the fire detector malfunction detection. When button 1001 is selected, the display of the settings screen changes as shown in settings screen 900. When the batch setting button 1002 is selected, all setting items are disabled. The items that are disabled are, for example, the display device 10 and the fire receiver 30. That is, even if a specified fire detector 40 detects a fire or a malfunction, the sound notification, the alarm notification, and the history recording will not be performed. The background color of button 1001 is different from the background colors of buttons 901-906. Buttons that are disabled, like button 1001, are displayed with a different appearance than buttons that are enabled.

[0040] Refer to Figure 5 again. In step S504, the display device 10 accepts input for the recovery time for the selected item for which the unmonitored setting input was received in step S503.

[0041] Figure 11 is an example of the settings screen 1100. The settings screen 1100 is displayed when an unmonitored setting is entered in step S503 (i.e., on the settings screen 900). Figure 11 shows the recovery time 1101 and the OK button 1102. The recovery time 1101 is the time it takes to restore the unmonitored setting to a monitored setting. The recovery time 1101 is entered through user operation. The user can set any recovery time 1101. After the recovery time 1101 is entered, if the OK button 1102 is selected through user operation, the unmonitored setting process proceeds to step S505.

[0042] Refer to Figure 5 again. In step S505, the display device 10 stores the unmonitored settings received in step S502 in the unmonitored settings database 800. If multiple fire detectors 40 are specified in step S502, the settings received in steps S503 and S504 are written to the unmonitored settings database 800 with a common setting value for all of the specified fire detectors 40.

[0043] 2.2.2 Notification of Status Information Figure 12 is a sequence chart illustrating the operation of the status information notification process. The fire alarm receiver 30 constantly queries the fire detector 40 for status information. If the status information of the fire detector 40 is not normal, the process shown in Figure 12 is initiated. Not normal status information means that the status information indicates fire detection, a malfunction of the fire detector 40, or that the measurement value from the sensor does not meet a predetermined standard.

[0044] In step S1201, the fire detector 40 transmits status information and its own address to the fire receiver 30. The status indicated in the transmitted status information is either fire detection or a malfunction of the fire detector 40. The fire receiver 30 receives the status information from the fire detector 40.

[0045] In step S1202, the fire alarm receiver 30 records the history in the storage 303. Specifically, it records the current time obtained from the fire alarm receiver 30's time management function (not shown), the status information obtained in step S1201, and the address of the fire detector 40 that is the source of the transmission. In addition, the fire alarm receiver 30 stores in the storage 303 information indicating that an abnormality has occurred in the monitored space, as well as the current time, separately from the history.

[0046] In step S1203, the fire alarm receiver 30 refers to the monitoring setting database 1300 and transmits status information and information indicating the notification method to the display device 10. The display device 10 receives status information and information indicating the notification method from the fire alarm receiver 30.

[0047] Figure 13 illustrates the monitoring setting database 1300. The monitoring setting database 1300 is stored in the fire alarm receiver 30. The monitoring setting database 1300 is a database that stores monitoring settings indicating the method of notifying status information. The monitoring setting database 1300 consists of detector ID 1301, fire detector status 1302, and setting presence / absence 1303. Detector ID 1301 is an ID for uniquely identifying each of the fire detectors 40, and is an ID common to detector ID 801. Fire detector status 1302 is the status of the fire detector 40, reflecting the information set in setting presence / absence 1303. Fire detector status 1302 is, for example, fire detected or malfunction. Setting presence / absence 1303 indicates whether or not the setting for notifying status information is set. In the monitoring setting database 1300, all settings have monitoring settings, and "Yes" is stored for all setting presence / absence 1303. The setting status 1303 is further divided into setting items for sound activation 1304, alarm display 1305, and history recording 1306. When the fire receiver 30 receives status information from the fire detector 40, it determines the notification method. For example, in step S1201, when the fire receiver 30 receives status information indicating that a fire has been detected by a fire detector 40 with detector ID 1301 "2", it determines to perform sound notification, display notification, and history recording. In step S1202, the fire receiver 30 transmits information to the display device 10 indicating the notification method determined by the fire receiver 30. The contents of the monitoring setting database 1300 can be changed by the user operating the fire receiver 30.

[0048] Refer to Figure 12 again. In step S1204, the display device 10 refers to the unmonitored setting database 800 and re-determines the notification method. For example, if the status information received in step S1201 indicates that the fire detector 40 with detector ID 801 (i.e., detector ID 1301) "2" has detected a fire, the display device 10 determines that it will not make an audible notification because the fire detector with detector ID 801 "2" is set to unmonitored for the "sound alarm" setting (i.e., it is set not to make an audible notification). Also, if the information indicates that the fire detector 40 with detector ID 801 "2" has detected a fire, the display device 10 determines that it will not make an audible notification because the fire detector with detector ID 801 "2" is also set to unmonitored for the "history recording" setting (i.e., it is set not to record history). The display device 10 determines that, for setting items that have not been set as unmonitored in the unmonitored setting database 800, it will provide notification according to the notification method received in step S1203. In other words, the display device 10 determines that it will provide notification by display, but will not provide notification by sound or record the history.

[0049] In step S1205, the display device 10 notifies the status information according to the determination result in step S1203. For example, if the status information indicates that the fire detector 40 with detector ID 1301 "2" has detected a fire, the display device 10 will not provide an audible notification or record the history because the fire detector 40 with detector ID 1301 "2" is set to "unmonitored" for both the "sound alarm" setting and the "history recording" setting. On the other hand, regarding the "alarm display" setting, the fire detector 40 with detector ID 1301 "2" is not set to "unmonitored," so the display device 10 will provide a display notification.

[0050] In this way, if some of the fire detectors 40 are set to be unmonitored, it is possible to prevent notifications from being sent by certain notification methods even in situations where the fire detectors 40 might mistakenly detect an abnormality, such as during facility renovation or expansion work. Furthermore, the user can easily set multiple fire detectors 40 to be unmonitored on the map using the display device 10.

[0051] In step S1202, information indicating that an abnormality occurred in the monitored space was stored. However, after it is confirmed that the abnormality in the monitored space has been resolved, information indicating that no abnormality occurred in the monitored space is newly stored, along with the time the operation was performed, according to the operator's operation of the fire alarm receiver 30.

[0052] 2.2.3 Restoring to Monitoring State Figure 14 is a flowchart illustrating the operation of the recovery process in the display device 10. The display device 10 obtains the current time at predetermined intervals from the clock function built into the display device 10 itself. When the current time reaches the recovery time entered in step S504, in step S1401, the display device 10 determines that the current time has reached the recovery time that was entered in step S504.

[0053] In step S1402, the display device 10 restores the unmonitored setting to the monitored setting. Specifically, it rewrites the setting status 803 for the setting item that was determined to have reached its recovery time in step S1401. Specifically, the display device 10 queries the fire alarm receiver 30 for the setting value of the setting item in the monitoring setting database 1300 that matches the setting item of the fire detector 40 that has reached its recovery time. The display device 10 rewrites the setting status 803 for the queryed setting value. For example, if the fire detector 40 that has reached its recovery time is the fire detector 40 corresponding to detector ID 801 "2", the state 802 of that fire detector is "fire detected", and the setting item to be restored is sound alarm 805, the display device 10 rewrites the setting value of sound alarm 805 to the setting value of sound alarm 1304 of the record where detector ID 1301 is "2" and the state 1302 of the fire detector is "fire detected". In this way, by automatically changing the unmonitored setting to a monitored setting within a predetermined recovery time, the effort required for users to change the setting from unmonitored to monitored can be reduced.

[0054] 3. Variant The present invention is not limited to the embodiments described above, and various modifications are possible. Several modifications are described below. Two or more of the modifications described below may be used in combination.

[0055] The device that stores the unmonitoring settings database 800 is not limited to the display device 10, but may be, for example, the fire alarm receiver 30. If the unmonitoring settings database 800 is stored in the fire alarm receiver 30, the display device 10 transmits information related to the unmonitoring settings entered in the display device 10 to the fire alarm receiver 30 and instructs it to rewrite the unmonitoring settings database 800. The fire alarm receiver 30 rewrites the unmonitoring settings database 800 according to the information related to the unmonitoring settings. In this case, the fire alarm receiver 30 generally instructs the display device 10 on the notification method according to the monitoring settings database 1300, but if an unmonitoring setting has been made in the unmonitoring settings database 800, it reflects the unmonitoring setting and instructs the display device 10 on the notification method. Alternatively, instead of reflecting the unmonitoring setting in the unmonitoring settings database 800, the value of the setting status 1303 in the monitoring settings database 1300 itself may be rewritten. When the unmonitored setting is reflected in the monitoring setting database 1300, the monitoring setting database 1300 also stores the recovery time and the setting status 1303 before they were overwritten.

[0056] The specific system configuration of the display system S is not limited to the examples of embodiments. For example, the display device 10 and the fire alarm receiver 30 may be connected by a network, and the fire alarm receiver 30 and the fire detector 40 may also be connected by a network. Furthermore, terminal equipment is not limited to fire detectors. At least some of the terminal equipment used in the display system S may be gas detectors, sprinklers, fire pumps, fire dampers, fire doors, or surveillance cameras.

[0057] In the unmonitored setting, the notification methods that can be configured are not limited to audible notifications, display notifications, or history recording. In place of, or in addition to, at least some of these, "notification by message to a mobile phone terminal" may be adopted as a configuration item.

[0058] Specific examples of unmonitored settings are not limited to those in this embodiment. In this embodiment, a setting where the presence / absence of setting 803 is "none" is considered an unmonitored setting, but a setting where the presence / absence of setting 803 is "present" may also be considered an unmonitored setting. For example, if the setting item is "Do not display alarm" and that setting is "present", then no notification is sent to the display device 10, and this can be considered an unmonitored setting.

[0059] The image objects placed on the map of the monitored space are not limited to the examples described in the embodiments, and only need to be distinguishable between designated fire detectors 40 and undesignated fire detectors 40. Designated fire detectors 40 and undesignated fire detectors 40 only need to differ to an extent that they are distinguishable in appearance, such as the shape, color, size, and temporal changes (e.g., flashing) of the image objects.

[0060] After an unmonitored setting is entered on the settings screen 900, the settings screen 1100 is not necessarily displayed; it does not have to be displayed. In this case, the recovery time may be automatically set to a predetermined default value. The default value is, for example, 0:00 AM 14 days after the date the unmonitored setting was entered.

[0061] The designation of fire detectors 40 to be set to unmonitored is not limited to being done by drag operation. For example, fire detectors 40 to be set to unmonitored may be designated by the user selecting multiple image objects 601 by clicking or tapping consecutively on the map within a predetermined time. Alternatively, all fire detectors 40 located in a selected room may be selected by the user selecting any room from among multiple rooms separated on the map by clicking or tapping on the room on the map.

[0062] Instead of determining the notification method in step S1203, the display device 10, which has received an instruction to change the operating state or operating setting of the designated fire detector 40, may send a change instruction to the designated fire detector 40, and that fire detector 40 may notify the fire receiver 30 using a notification method in accordance with that change instruction. For example, if a fire detector 40 that is set to not make an audible notification when a fire is detected detects a fire, that fire detector 40 will instruct the fire receiver 30 not to make an audible notification.

[0063] The correspondence between functional elements and hardware elements in the display system S is not limited to those exemplified in the embodiments. For example, some of the functions described as those of the display device 10 in the embodiments may be implemented on another server. For example, some or all of the functions of the display device 10 may be provided on the fire alarm receiver 30. Alternatively, some of the functions described as those of the display device 10 in the embodiments may be implemented on other devices on the network. Also, for example, some of the functions described as those of the fire alarm receiver 30 in the embodiments may be implemented on another server. Alternatively, some of the functions described as those of the fire alarm receiver 30 in the embodiments may be implemented on other devices on the network.

[0064] The operation of the display system S is not limited to the examples described above. The processing steps of the display system S may be rearranged as long as they do not contradict each other. In addition, some of the processing steps of the display system S may be omitted.

[0065] The various programs exemplified in the embodiments may be provided by download via a network such as the Internet, or they may be provided recorded on a computer-readable non-temporary recording medium such as a DVD-ROM (Digital Versatile Disc Read Only Memory). [Explanation of symbols]
