[0015] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0016] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0017] (Embodiment) [composition] The configuration of the detection system according to the embodiment will be described below. Fig. 1 is a block diagram showing the functional configuration of the detection system according to the embodiment.

[0018] 1 is a system capable of notifying that a fire has occurred in a building 90 under construction. The building 90 here is, for example, an apartment building, a factory, a research facility, a medical facility, or an accommodation facility, but is not limited thereto.

[0019] The detection system 10 comprises a plurality of fire alarms 20, a repeater 30, a base station 40, a server device 60, and an information terminal 70. It is sufficient that the detection system 10 comprises at least one fire alarm 20. The detection system 10 comprises one repeater 30 for the plurality of fire alarms 20, but the detection system 10 may comprise a plurality of repeaters 30 for the plurality of fire alarms 20, for example, a plurality of repeaters 30 in one-to-one correspondence with the plurality of fire alarms 20.

[0020] The fire alarm 20 is temporarily installed in the building 90 under construction to detect the occurrence of a fire in the building 90, at least until the building 90 is completed. The fire alarm 20 is an example of a detector, and a plurality of fire alarms 20 is an example of a detector system. The fire alarm 20 includes a smoke sensor 21, a first communication unit 22, a second communication unit 23, a control unit 24, a memory unit 25, an alarm unit 26, a housing 27, and an operation unit 28.

[0021] The smoke sensor 21 is a sensor for detecting the occurrence of a fire in the building under construction 90. The smoke sensor 21 includes a light-emitting element such as a light-emitting diode, and a light-receiving element such as a photodiode. In the smoke sensor 21, the light emitted by the light-emitting element is scattered by smoke particles and enters the light-receiving element, and the smoke sensor 21 can detect the occurrence of smoke based on the amount of light that enters the light-receiving element.

[0022] The fire alarm 20 may include a heat sensor (temperature sensor) instead of the smoke sensor 21 or in addition to the smoke sensor 21. The heat sensor is another example of a sensor for detecting the occurrence of a fire.

[0023] The first communication unit 22 is a communication circuit for the fire alarm device 20 to communicate with the repeater 30. The first communication unit 22 is, for example, a wireless communication circuit that performs wireless communication with the repeater 30. The communication standard of the communication performed by the first communication unit 22 is not particularly limited.

[0024] The second communication unit 23 is a communication circuit for the fire alarm 20 to communicate with a receiver (described later). The second communication unit 23 is, for example, a wireless communication circuit that performs wireless communication with the receiver, but may also be a wired communication circuit that performs wired communication with the receiver. The communication standard of the communication performed by the second communication unit 23 is not particularly limited.

[0025] When the smoke sensor 21 detects the occurrence of a fire, the control unit 24 activates the alarm unit 26 to alert people located in the building under construction 90. When the smoke sensor 21 detects the occurrence of a fire, the control unit 24 notifies the user of the information terminal 70 of the occurrence of a fire by transmitting notification information to the server device 60 using the first communication unit 22 (or the second communication unit 23). The control unit 24 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the control unit 24 are realized, for example, by the microcomputer or processor constituting the control unit 24 executing a computer program stored in the storage unit 25.

[0026] The storage unit 25 is a storage device that stores computer programs executed by the control unit 24. The storage unit 25 is realized by, for example, a semiconductor memory.

[0027] When the control unit 24 determines that a fire has occurred, the notification unit 26 issues a notification to people located in the building under construction 90. The notification unit 26 is realized by, for example, at least one of a speaker and a light-emitting element, and issues a notification by at least one of sound and light.

[0028] The housing 27 accommodates the smoke sensor 21, the first communication unit 22, the second communication unit 23, the control unit 24, the storage unit 25, the notification unit 26, and the operation unit 28. The housing 27 is formed of, for example, a resin material.

[0029] The operation unit 28 receives operations from a user. The operation unit 28 is, for example, a push button provided on the housing 27.

[0030] The repeater 30 is a gateway device that enables the fire alarm device 20 to communicate with the base station 40. In other words, the repeater 30 is a device that enables the fire alarm device 20 to communicate with the server device 60 through a mobile communication network. The repeater 30 is temporarily installed in, for example, a building 90 under construction. The base station 40 is a base station of the mobile communication network and is located, for example, outside the building 90 under construction.

[0031] The server device 60 notifies the information terminal 70 of the occurrence of a fire based on the notification information received from the fire alarm 20. The server device 60 includes a communication unit 61, an information processing unit 62, and a storage unit 63.

[0032] The communication unit 61 is a communication circuit for the server device 60 to communicate with the fire alarm 20 and the information terminal 70. The communication unit 61 is, for example, a wired communication circuit for performing wired communication, but may also be a wireless communication circuit for performing wireless communication. The communication standard of the communication performed by the communication unit 61 is not particularly limited.

[0033] The information processing unit 62 performs information processing for notifying the occurrence of a fire and for notifying the maintenance of equipment. The information processing unit 62 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the information processing unit 62 are realized, for example, by the microcomputer or processor constituting the information processing unit 62 executing a computer program stored in the storage unit 63.

[0034] The storage unit 63 is a storage device that stores computer programs and the like executed by the information processing unit 62. The storage unit 63 is realized by, for example, a semiconductor memory.

[0035] The information terminal 70 is a portable information terminal such as a personal computer, a tablet terminal, or a smartphone. The information terminal 70 is used by a user to receive a notification that a fire has occurred in the building under construction 90. The user of the information terminal 70 may be a worker working on the building under construction 90, or a manager managing the workers. In FIG. 1, the information terminal 70 is located outside the building under construction 90, but if the user of the information terminal 70 is a worker, the information terminal 70 is located in the building under construction 90.

[0036] The information terminal 70 includes a display unit 71 that displays an image (notification screen). The display unit 71 is realized by a display panel such as a liquid crystal panel or an organic EL panel.

[0037] [Fire alarm installation status] The fire alarm 20 is usually installed in the ceiling of the space within the building 90, but since there may be periods during which the ceiling of the building 90 under construction is not yet formed, there is room for consideration as to how to install the fire alarm 20 in the building 90 under construction.

[0038] Furthermore, in the building 90 under construction, locations where fires are likely to occur, such as storage locations for flammable materials and hot work sites, will change as the construction of the building 90 progresses. Therefore, it is desirable to install the fire alarm 20 so that its installation location can be changed flexibly.

[0039] In the detection system 10, for example, the fire alarm 20 is attached to a stand, which is a portable piece of equipment, and the stand with the fire alarm 20 attached is installed in a building 90 under construction. Figure 2 is a diagram showing an example of a stand with the fire alarm 20 attached.

[0040] The stand 80 is, in other words, a mounting base, and is made of, for example, a metal material, but may be made partially or entirely of a resin material. Also, a portion of the stand 80 may be made of wood. The repeater 30 may also be attached to the stand 80. Fig. 3 is a diagram showing an example of a stand 80 to which the fire alarm 20 and the repeater 30 are attached.

[0041] The installation location of the fire alarm 20 attached to the stand 80 as described above can be easily changed by changing the installation position of the stand 80. In other words, the fire alarm 20 is useful as a fire alarm whose installation location can be easily changed.

[0042] In addition, the fire alarm 20 has the advantage that it is not attached to the building 90 under construction itself and therefore does not interfere with construction work. Furthermore, if the fire alarm 20 is installed at a height equivalent to the ceiling of the completed building 90 using the stand 80, the fire alarm 20 can exhibit the same performance as if it were installed on the ceiling.

[0043] [Fire outbreak notification behavior] Next, a description will be given of the operation of notifying the occurrence of a fire by the detection system 10. Fig. 4 is a sequence diagram of the operation of notifying the occurrence of a fire by the detection system 10.

[0044] When the control unit 24 of the fire alarm 20 determines that the smoke level (amount of smoke) sensed by the smoke sensor 21 is equal to or greater than the threshold (S11), it activates the notification unit 26 to notify workers located in the building under construction 90 of the occurrence of a fire (S12). The workers are notified by at least one of sound and light.

[0045] In addition, control unit 24 uses first communication unit 22 to transmit notification information to server device 60 (S13). Although not shown in detail in FIG. 4, the notification information is transmitted to server device 60 via relay 30 and base station 40.

[0046] The communication unit 61 of the server device 60 receives the notification information. The information processing unit 62 uses the communication unit 61 to transmit the received notification information to the information terminal 70 that has been registered in advance (S14).

[0047] The information terminal 70 receives the notification information, and based on the received notification information, displays a notification screen for notifying that a fire has broken out in the building under construction 90 on the display unit 71 provided in the information terminal 70 (S15). Fig. 5 is a diagram showing an example of the notification screen. In addition to displaying the notification screen, the information terminal 70 may output a notification sound from a speaker (not shown) provided in the information terminal 70 for notifying that a fire has broken out in the building under construction 90.

[0048] The storage unit 53 of the server device 50 stores information associating the identification information of the fire alarm 20 with information relating to the installation location of the fire alarm 20. If the information relating to the installation location includes the name of a building 90 under construction, the name of the building 90 in which the fire occurred can be displayed on the notification screen as shown in Fig. 5. Although not shown, if the information relating to the installation location includes information regarding the floor on which the fire alarm 20 is installed and the area (district) to which the building 90 belongs, the floor on which the fire occurred and the area in which the fire occurred can be displayed on the notification screen.

[0049] Furthermore, if the information regarding the installation location includes information indicating the coordinates (e.g., latitude and longitude) of the building 90, a map can be displayed on the notification screen and the location of the fire can be indicated on the map. In this case, for example, at least one of the server device 50 and the information terminal 70 communicates with a server device (not shown) that manages map information to obtain map information for displaying the map on the notification screen.

[0050] In this way, by installing (temporarily installing) a fire alarm 20 in the building under construction 90, the detection system 10 can alert workers located within the building under construction 90 of the occurrence of a fire in the building under construction 90, and also notify the user of the information terminal 70.

[0051] [Configuration of the detection system after the building is completed] When the building 90 under construction is completed, a different fire alarm from the fire alarm 20 used in the building 90 under construction is generally installed in the completed building 90. In contrast, in the detection system 10, the fire alarm 20 can be continuously used even after the building 90 is completed.

[0052] After the building 90 is completed, the manner in which the fire alarm 20 is installed in the building 90 is stipulated by law etc. Specifically, the fire alarm 20 must be installed in a predetermined location, such as the ceiling of a space within the building 90, and must be communicatively connected to a predetermined receiver. Fig. 6 is a block diagram showing a first example of the functional configuration of the detection system after the building 90 is completed.

[0053] 6, the detection system 11 after the building 90 is completed includes a plurality of fire alarms 20, a receiver 50, a server device 60, and an information terminal 70. It is sufficient that the detection system 11 includes at least one fire alarm 20.

[0054] The receiver 50 is a device that is installed in a disaster prevention center or a central control room in the completed building 90, and receives notification information from the fire alarm 20 and transmits the received notification information to the server device 60. The receiver 50 is a dedicated device for constructing a fire alarm system. There are various types of receivers 50, such as a P-type receiver and an R-type receiver.

[0055] As can be seen by comparing Fig. 1 and Fig. 6, the fire alarm 20 communicatively connects to the repeater 30 using the first communication unit 22 while the building 90 is under construction (Fig. 1), and communicatively connects to the receiver 50 using the second communication unit 23 after the building 90 is completed (Fig. 6). In other words, the fire alarm 20 is provided with the second communication unit 23 that is not used during the construction of the building 90, in order to communicatively connect to the receiver 50 after the building 90 is completed. This allows the fire alarm 20 provided in the detection system 10 in which the building 90 is under construction to continue to be used in the detection system 11 after the building 90 is completed.

[0056] When the building 90 is under construction, the server device 60 receives the notification information through the repeater 30 and the base station 40, and when the building 90 is completed, the server device 60 receives the notification information through the receiver 50.

[0057] [Example 1 of fire alarm transfer procedure] Next, a procedure for transferring the fire alarm 20 from the detection system 10 in Fig. 1 to the detection system 11 in Fig. 6 will be described. Fig. 7 is a flowchart of an example 1 of the transfer procedure for the fire alarm 20.

[0058] The installer performing the transition work removes the fire alarm 20 from the stand 80 and installs it on the ceiling inside the completed building 90 (S21). The installer also installs the receiver 50 in a disaster prevention center or a central control room (S22). If the second communication unit 23 of the fire alarm 20 and the receiver 50 perform wired communication, the installer performs wiring work to wire-connect the fire alarm 20 (second communication unit 23) and the receiver 50 (S23). Note that if the second communication unit 23 and the receiver 50 perform wireless communication, the work in step S23 can be omitted.

[0059] Next, the installer performs a predetermined operation on the operation unit 28 of the fire alarm 20 (S24). The predetermined operation is, for example, an operation of pressing the operation unit 28 (push button), but it may also be a long press operation or the like.

[0060] The control unit 24 of the fire alarm 20 is communicatively connected to the repeater 30 using the first communication unit 22 before the predetermined operation is accepted, but when the predetermined operation is accepted, it communicatively connects to the receiver 50 using the second communication unit 23 (S25). At this time, the first communication unit 22 may be powered off in response to the predetermined operation, or may be disabled while still powered on in response to the predetermined operation. The second communication unit 23 may be powered on from off in response to the predetermined operation, or may be disabled while still powered on before the predetermined operation is accepted, and may be enabled in response to the predetermined operation.

[0061] In this way, when the building 90 is completed, the control unit 24 of the fire alarm 20 performs control (processing of step S25) to change the destination of the notification information from the repeater 30 to the receiver 50. This allows the builder to transfer the fire alarm 20 from the detection system 10 used in the building 90 under construction to the detection system 11 used in the completed building 90.

[0062] 7, the control unit 24 switches between the first communication unit 22 and the second communication unit 23 based on a predetermined operation received by the operation unit 28, but the control unit 24 may switch between the first communication unit 22 and the second communication unit 23 based on a switching signal transmitted by an external device. The external device is, for example, the receiver 50, an infrared remote controller, or a general-purpose mobile terminal on which a predetermined application program is installed.

[0063] In this case, the fire alarm 20 receives the switching signal, for example, by the first communication unit 22, but may also be provided with another communication unit (such as an infrared light receiving unit) for receiving the switching signal as necessary. This can save the installer the trouble of operating the operation unit 28.

[0064] In addition, when the second communication unit 23 of the fire alarm 20 and the receiver 50 perform wireless communication, the communication connection of step S25 may be executed in response to the transmission of a signal from the fire alarm 20 to the receiver 50, or in response to the transmission of a signal from the receiver 50 to the fire alarm 20.

[0065] Furthermore, the configuration of the detection system used in the building under construction 90 is not limited to that of the detection system 10. For example, if the first communication unit 22 of the fire alarm 20 is a communication circuit that can communicate directly with the base station 40 without going through the repeater 30, the detection system 10 does not need to include the repeater 30. FIG. 8 is a block diagram showing the functional configuration of a detection system that does not include the repeater 30.

[0066] The control unit 24 of the fire alarm 20 provided in the detection system 10a shown in FIG. 8 can perform control (processing of step S25) to change the destination of notification information from the base station 40 to the receiver 50 when the building 90 is completed, in accordance with the procedure in FIG. 7.

[0067] [Example 2 of fire alarm transition procedure] The configuration of the detection system after the building 90 is completed is not limited to the configuration of the detection system 11 in Fig. 6. Fig. 9 is a block diagram showing a second example of the functional configuration of the detection system after the building 90 is completed.

[0068] The detection system 11a shown in Fig. 9 includes a repeater 30a between the fire alarm 20 and the receiver 50. The repeater 30a is a repeater different from the repeater 30, and is the same as the repeater 30 in that it can communicate with the first communication unit 22 of the fire alarm 20, but differs from the repeater 30 in that it cannot communicate with the base station 40. The repeater 30a can also communicate with the receiver 50.

[0069] The following describes a procedure for transitioning the fire alarm 20 from the detection system 10 in Fig. 1 to the detection system 11a in Fig. 9. Fig. 10 is a flowchart of a second example of the transition procedure for the fire alarm.

[0070] The installer removes the fire alarm 20 from the stand 80 and installs it on the ceiling inside the completed building 90 (S31). The installer also installs the receiver 50 in a disaster prevention center or a central control room (S32), and further installs the repeater 30a inside the building 90 (S33).

[0071] When the repeater 30a and the receiver 50 perform wired communication, the installer performs wiring work to wire-connect the repeater 30a and the receiver 50 (S34). Note that when the repeater 30a and the receiver 50 perform wireless communication, the work in step S34 can be omitted.

[0072] Next, the installer disconnects the communication connection between the fire alarm device 20 and the repeater 30, and establishes a communication connection between the fire alarm device 20 and the repeater 30a (S35). In other words, the installer replaces the repeater 30 with the repeater 30a. Any existing method may be used to disconnect and establish the communication connection.

[0073] In this way, in Example 2 of the transition procedure for the fire alarm 20, the repeater 30a is installed in the building 90 in place of the repeater 30 that was installed in the building 90 during the construction of the building 90. By replacing (replacing) the repeater 30 with the repeater 30a, the builder can transition the fire alarm 20 from the detection system 10 used in the building 90 under construction to the detection system 11a used in the completed building 90. In this case, the fire alarm 20 does not need to have the second communication unit 23 because it is only necessary for the fire alarm 20 to be communicatively connected to the repeater 30 and the repeater 30a and does not need to communicate directly with the receiver 50. If the second communication unit 23 is omitted from the fire alarm 20, the configuration of the fire alarm 20 can be simplified.

[0074] The operation of the detection system 11a when a fire is detected will be described below. When a fire is detected by the fire alarm 20 installed in a building 90 under construction, the repeater 30 of the detection system 10 transmits the notification information received from the fire alarm 20 to the base station 40. In contrast, when a fire is detected by the fire alarm 20 after the building 90 is completed, the repeater 30a transmits the notification information received from the fire alarm 20 to the receiver 50. In other words, when the building 90 is completed, the destination of the notification information is changed from the base station 40 to the receiver 50.

[0075] [Example 3 of fire alarm transfer procedure] In the above-mentioned example 1 of the transition procedure of the fire alarm 20, the fire alarm 20 changes the communication destination, but the repeater 30 may change the communication destination. Figs. 11 and 12 are block diagrams showing the functional configuration of a detection system including a repeater having a communication destination switching function. Fig. 11 is a block diagram showing the functional configuration of a detection system 10b in which a building 90 is being constructed, and Fig. 12 is a block diagram showing the functional configuration of a detection system 11b after the building 90 is completed. As shown in Figs. 11 and 12, the detection system 10b and the detection system 11b include a repeater 30b. Specifically, the repeater 30b includes a first communication unit 31, a second communication unit 32, a third communication unit 33, a control unit 34, and a memory unit 35.

[0076] The first communication unit 31 is a communication circuit for the repeater 30b to communicate with the base station 40. The first communication unit 31 is, for example, a wireless communication circuit that performs wireless communication with the base station 40. The communication standard of the communication performed by the first communication unit 31 is not particularly limited.

[0077] The second communication unit 32 is a communication circuit for the repeater 30b to communicate with the receiver 50. The second communication unit 32 is, for example, a wireless communication circuit that performs wireless communication with the receiver 50, but may also be a wired communication circuit that performs wired communication with the receiver 50. The communication standard of the communication performed by the second communication unit 32 is not particularly limited.

[0078] The third communication unit 33 is a communication circuit for the repeater 30b to communicate with the multiple fire alarm devices 20. The second communication unit 32 is, for example, a wireless communication circuit that performs wireless communication with the multiple fire alarm devices 20, but may also be a wired communication circuit that performs wired communication with the multiple fire alarm devices 20. The communication standard of the communication performed by the third communication unit 33 is not particularly limited.

[0079] It should be noted that if the repeater 30 is capable of communicating with a plurality of fire alarm devices 20 using the first communication unit 31 or the second communication unit 32, the third communication unit 33 can be omitted.

[0080] When the fire alarm 20 detects the occurrence of a fire, the control unit 34 switches between transmitting the notification information received from the fire alarm 20 to the base station 40 or to the receiver 50. The control unit 34 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the control unit 34 are realized, for example, by the microcomputer or processor constituting the control unit 34 executing a computer program stored in the storage unit 35.

[0081] The storage unit 35 is a storage device that stores computer programs and the like executed by the control unit 34. The storage unit 35 is realized by, for example, a semiconductor memory.

[0082] The following describes a procedure for transitioning the fire alarm 20 from the detection system 10b in Fig. 11 to the detection system 11b in Fig. 12. Fig. 13 is a flowchart of example 3 of the transition procedure for the fire alarm 20.

[0083] The installer removes the fire alarm 20 from the stand 80 and installs it on the ceiling in the completed building 90 (S41). The installer also installs the receiver 50 in a disaster prevention center or a central control room (S42), and further installs the repeater 30b in the building 90 (S43). If the repeater 30b is attached to the stand 80 (see FIG. 3), the repeater 30b is removed from the stand and then installed.

[0084] If the repeater 30b and the receiver 50 perform wired communication, the installer performs wiring work to wire-connect the repeater 30b and the receiver 50 (S44). Note that if the repeater 30b and the receiver 50 perform wireless communication, the work in step S44 can be omitted.

[0085] Next, the installer performs a predetermined operation on the repeater 30b (S45). The predetermined operation is, for example, an operation of pressing an operation unit (push button) provided on the repeater 30b, but may also be a long press operation or the like.

[0086] Before the predetermined operation is accepted, the control unit 34 of the repeater 30b is connected to the base station 40 by using the first communication unit 31, but when the predetermined operation is accepted, the control unit 34 connects to the receiver 50 by using the second communication unit 32 (S46). At this time, the first communication unit 31 may be powered off in response to the predetermined operation, or may be disabled while still powered on in response to the predetermined operation. The second communication unit 32 may be powered on from off in response to the predetermined operation, or may be disabled while still powered on before the predetermined operation is accepted, and may be enabled in response to the predetermined operation.

[0087] In this way, the control unit 34 of the repeater 30b performs control (processing of step S46) to change the destination of the notification information from the base station 40 to the receiver 50 when the building 90 is completed. This allows the builder to transfer the fire alarm 20 from the detection system 10b used in the building 90 under construction to the detection system 11b used in the completed building 90. In this case, the fire alarm 20 only needs to be communicatively connected to the repeater 30b, and does not need to communicate directly with the receiver 50, so there is no need to include the second communication unit 23. If the second communication unit 23 is omitted from the fire alarm 20, the configuration of the fire alarm 20 can be simplified.

[0088] 13, the control unit 34 switches between the first communication unit 31 and the second communication unit 32 based on a predetermined operation received by the operation unit, but the control unit 34 may switch between the first communication unit 31 and the second communication unit 32 based on a switching signal transmitted by an external device. The external device is, for example, the receiver 50, an infrared remote controller, or a general-purpose mobile terminal on which a predetermined application program is installed.

[0089] In this case, the repeater 30b receives the switching signal by, for example, the first communication unit 31, but may also include another communication unit (such as an infrared light receiving unit) for receiving the switching signal as necessary. This can save the installer the trouble of operating the operation unit.

[0090] Furthermore, when wireless communication is performed between the second communication unit 32 of the repeater 30b and the receiver 50, the communication connection in step S46 may be executed in response to the transmission of a signal from the repeater 30b to the receiver 50, or in response to the transmission of a signal from the receiver 50 to the repeater 30b.

[0091] [Variations] In the above-mentioned example 1 of the transition procedure of the fire alarm 20, the control unit 24 of the fire alarm 20 switched between the first communication unit 22 and the second communication unit 23 before and after the building 90 was completed. Here, if a single communication unit (communication circuit or communication module) can be used to communicate with both the repeater 30 and the receiver 50, the fire alarm 20 may be provided with the single communication unit and switch the communication partner (destination of notification information) of the single communication unit. In other words, it is not essential that the fire alarm 20 be provided with two types of communication units and that the control unit 24 switch between the two types of communication units.

[0092] In the above-mentioned example 3 of the transition procedure of the fire alarm 20, the control unit 34 of the repeater 30b switches between the first communication unit 31 and the second communication unit 32 before and after the building 90 is completed. Here, when a single communication unit (communication circuit or communication module) can be used to connect to both the base station 40 and the receiver 50, the repeater 30b may be provided with the single communication unit and switch the communication partner (destination of notification information) of the single communication unit. In other words, it is not essential that the repeater 30b be provided with two types of communication units and that the control unit 34 switch between the two types of communication units.

[0093] In addition, in the above embodiment, an example has been described in which the detection systems 10, 10a, and 10b equipped with the fire alarm 20 continue to be used even after the building 90 is completed, but a detection system equipped with a detector other than the fire alarm 20 may also continue to be used after the building 90 is completed.

[0094] For example, if a burglary alarm that sounds when it detects an intruder using a human presence sensor or the like is installed in the building 90 under construction, the detection system including the burglary alarm may continue to be used after the building 90 is completed. According to the present invention, a detection system including a detector that is installed in the building 90 under construction and detects some kind of event can continue to be used after the building 90 is completed.

[0124] (Other embodiments) Although the embodiment has been described above, the present invention is not limited to the above embodiment.

[0125] For example, in the above embodiment, the detection system is realized by a plurality of devices. In this way, when the detection system is composed of a plurality of devices, the components (particularly, functional components) of the detection system may be distributed in any manner among the plurality of devices.
