Description

[Technical field]

[0001] The present invention relates to an apparatus equipped with a fire receiving unit. [Background technology]

[0002] Conventionally, when constructing a fire alarm system in a building, a test device that is communicatively connected to terminal equipment has been proposed as a technology for performing operation checks and setting checks on the terminal equipment even when a fire receiver is not installed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-122489 A (pages 2-3) Summary of the Invention [Problem to be solved by the invention]

[0004] The test device described in Patent Document 1 is composed of a parent unit and a child unit each composed of a notebook computer, and can check the operation and settings of terminal devices even in buildings where no fire receiver is installed. However, the test device is a dedicated test device whose functions have been developed separately from the actual fire receiver. Even if the terminal device connected to the test device operates without any problems, the operation of the terminal device connected to the actual fire receiver may differ from the operation of the terminal device when the test device is connected. In that case, the operation check and setting check of the terminal device must be redone, which may result in an increase in the number of workers to avoid a longer construction period or an extension of the construction period, leading to an increase in construction costs. In addition, when a dedicated test device is used, a control program for the test device must be developed separately from the control circuit and control program that constitute the fire receiver. Therefore, the initial cost of developing a fire alarm system becomes large. In addition, the worker who uses the test device must learn how to use the test device separately from the actual fire receiver, which may lead to an increase in the burden on the worker.

[0005] The present invention has been made in light of the above-mentioned problems, and provides an apparatus that can suppress the increase in costs involved in developing and constructing a fire alarm system, and can reduce the burden on workers who check the operation and settings of terminal equipment. [Means for solving the problem]

[0006] The device according to the present invention comprises: It is a display A fire receiving unit having a display device, a terminal block, and an operation unit, and a case having a carrying means and accommodating the fire receiving unit, A first surface, which is the largest surface among the surfaces constituting the case, is formed with a first opening having substantially the same size as the first surface, The display device, the terminal block, and the operation unit are disposed in the case. The above No. 1 To the outside through an opening Positioned so that it is exposed ,before The display device, the terminal block, and the operation unit is disposed on the inside of the case with respect to the opening surface of the first opening. . In addition, the device of the present invention comprises a fire receiving unit having a display device which is a display, a terminal block, and an operating unit, and a case having a transportation means and accommodating the fire receiving unit, the case comprising a first housing having a first surface which is the largest surface among the surfaces constituting the case as its front surface and an internal storage space, a second housing which is connected to the first housing in an openable and closable manner, has a second surface which is the same size as the first surface and faces the first surface, and has an internal storage space, a first opening formed on the first surface and which is approximately the same size as the first surface, and a first cover which covers the first opening in an openable and closable manner, the display device, the terminal block, and the operating unit are accommodated in the first housing, and when the first cover is removed, the display device, the terminal block, and the operating unit are arranged so as to be exposed to the outside through the first opening of the case, and when the first cover is attached, the first cover constitutes at least a part of the first surface. Effect of the Invention

[0007] According to the present invention, since the fire receiving unit is housed in a case having a transport means, the device can be brought to any location in a building under construction and connected to a terminal device. Therefore, even if a fire receiver is not installed in the building, the operation and setting of the terminal device installed in the building can be checked. The device of the present invention is equipped with a fire receiving unit, and is not a dedicated test device whose functions have been developed separately from the fire receiver installed in the building. Therefore, by connecting the device of the present invention to check the operation and setting of the terminal device, it is possible to make the terminal device perform the same operation as when the fire receiver is connected to the terminal device. In addition, there is no need to develop a dedicated test device separate from the fire receiver. Therefore, the increase in the cost of developing and constructing the fire alarm system is suppressed. In addition, since the worker who checks the operation and setting of the terminal device does not need to learn how to operate a test device separate from the fire receiver, the burden on the worker is also reduced.

[0009] The device according to the present invention will be described below with reference to the drawings. The present invention is not limited to the following embodiments, and can be modified in various ways without departing from the spirit of the present invention. The present invention includes all combinations of possible configurations among the configurations shown in the following embodiments. The device shown in the drawings is an example of the device of the present invention, and the device of the present invention is not limited to the device shown in the drawings. In the following description, terms indicating directions (e.g., "upper", "lower", "right", "left", "front", "rear", etc.) are used as appropriate to facilitate understanding, but these are for explanation and do not limit the present invention. In each drawing, the same reference numerals are assigned to the same or equivalent parts, and this is common throughout the entire specification. In each drawing, the relative dimensional relationship or shape of each component may differ from the actual one.

[0010] Embodiment 1 Fig. 1 is a perspective view of the device 100 according to the first embodiment. Fig. 2 is a perspective view of the device 100 according to the first embodiment with a first cover 14 removed. The device 100 includes a case 10 and a fire receiving unit 30 housed in the case 10. A user can carry the fire receiving unit 30 using the case 10.

[0011] The case 10 includes a first housing 11, a second housing 12, and a carrying means 13. The first housing 11 and the second housing 12 are containers with an opening on one side. The first housing 11 and the second housing 12 are connected to each other via a hinge 20 (see Figs. 5 to 7) so as to be openable and closable. In the state shown in Figs. 1 and 2, the edges of the openings of the first housing 11 and the second housing 12, which are opposed to each other, are in contact with each other, and this state is called the closed state of the case 10. The first housing 11 and the second housing 12 are made of, for example, a synthetic resin or a metal. The first housing 11 and the second housing 12 may have the same shape and volume, or may have different shapes and volumes. In this embodiment, the volume of the second housing 12 is larger than the volume of the first housing 11.

[0012] The carrying means 13 is a structure for an operator to carry the device 100. In this embodiment, the carrying means 13 is a handle attached to the upper part of the second housing 12. Although the handle is shown in a laid-down state in Fig. 1 and Fig. 2, this handle can be rotated and raised by the user's operation, and the user can grip the handle in the raised state.

[0013] As shown in FIG. 2, a first opening 112 is formed in a first surface 111 constituting the front surface of the first housing 11. As shown in FIG. 1, this first opening 112 is covered by a first cover 14. The first cover 14 is provided so as to be separable from the case 10. The first housing 11 and the first cover 14 are connected by a lock mechanism 15. The lock mechanism 15 is a member for restricting the opening operation of the first cover 14, and has an engagement piece 151 attached undetachably to the first cover 14 and an engaged part 152 attached undetachably to the case 10. The hook-shaped engagement piece 151 is engaged with the engaged part 152, thereby preventing the first cover 14 from being detached from the case 10. The engagement piece 151 may be provided on the case 10, and the engaged part 152 may be provided on the first cover 14. The engaging piece 151 and the engaged part 152 are attached undetachably to the case 10 or the first cover 14, respectively, and therefore become one with the case 10 or the first cover 14 when the first cover 14 is removed from the case 10. Therefore, the locking mechanism 15 will not fall off and be lost when the first cover 14 is opened or closed. Also, as the locking mechanism 15, a screw for fixing the first cover 14 and the case 10 can be provided.

[0014] 1, a second cover 16 is provided on the second housing 12 at the rear of the case 10. As shown in FIG. 2, a second opening 122 is formed in the second housing 12, and this second opening 122 is covered by the second cover 16.

[0015] Around the first opening 112 of the first housing 11, one or more buffer members 17 protruding toward the outside of the case 10 are provided. The buffer members 17 protrude forward from the first surface 111 of the first housing 11, and function as legs when the case 10 is placed with the first surface 111 facing down. Therefore, when the case 10 is placed with the first surface 111 facing down, the operation display device 6 of the fire receiving unit 30 described later, exposed from the first opening 112, can be prevented from contacting the floor or an object on the floor. By using a material having elasticity such as rubber, synthetic resin, or urethane as the material of the buffer members 17, it is possible to suppress the impact when the buffer members 17 hit an object from being transmitted to the fire receiving unit 30.

[0016] Here, when the fire receiver receives a fire signal sent from a terminal device such as a fire detector or a repeater, it visually or audibly notifies the occurrence of a fire. When the fire receiver receives a fire signal, it outputs a signal notifying the occurrence of a fire to a terminal device such as an alarm device such as a buzzer or a light, a smoke control device such as a fire door or a shutter, or a fire extinguishing device, and operates the terminal device. The fire receiving unit 30 of this embodiment has a function of receiving a signal similar to that of the fire receiver and outputting a similar signal. The fire receiving unit 30 is configured as a part of a fire receiver installed in a building, and is recognized by the terminal device as a device that is substantially the same as the fire receiver in terms of input and output.

[0017] Generally, fire receivers are classified into wall-mounted and free-standing types. The dimensions of the wall-mounted fire receiver are, for example, about 850 mm×480 mm×150 mm (H×W×D). The weight is about 28 kg to 32 kg, for example, 31 kg. The dimensions of the free-standing fire receiver are, for example, about 2000 mm×600 mm×300 mm (H×W×D). The weight is about 95 kg to 100 kg, for example, 97 kg. In contrast, the fire receiving unit 30 has dimensions of, for example, about 505 mm×638 mm×231.5 mm (H×W×D). The weight of the fire receiving unit 30 is about 12 kg to 16 kg, for example, 14.5 kg. Thus, the dimensions and weight of the fire receiving unit 30 are smaller than those of the wall-mounted and free-standing fire receivers, making it relatively easy for an operator to carry it. The fire receiving unit 30 is smaller in size and weight than the fire receiver because the fire receiving unit 30 is mainly composed of the operation display unit and control circuit, which are components of the fire receiver.

[0018] The fire receiving unit 30 includes an operation display device 31, a terminal block 32, and an operation unit 33. The operation display device 31 is, for example, a liquid crystal display with a touch panel, and functions as a display device that accepts operations by an operator and displays information notifying the occurrence of a fire using characters or figures. The terminal block 32 is a group of terminals for electrically connecting a terminal device to the fire receiving unit 30. The operation unit 33 is an input device such as a switch or a button, and is used to operate the fire receiving unit 30. Note that a display device without a touch panel may be provided instead of the operation display device 31.

[0019] The operation display device 31, the terminal block 32, and the operation unit 33 are provided so as to be exposed to the outside of the case 10 when the first cover 14 is removed. In the example of FIG. 2, the operation display device 31, the terminal block 32, and the operation unit 33 are fitted in a first opening 112 formed in a first surface 111 of the first housing 11. With the first housing 11 and the second housing 12 in a closed state, an operator can access the operation display device 31, the terminal block 32, and the operation unit 33 simply by removing the first cover 14. Since an operator does not need to open the case 10 to access the operation display device 31, the terminal block 32, and the operation unit 33, operability for the operator can be improved.

[0020] Fig. 3 is a rear view of device 100 according to embodiment 1. Fig. 4 is a perspective view of device 100 according to embodiment 1 with second cover 16 removed. Second housing 12 is a member that constitutes the rear of case 10. As shown in Fig. 3, second surface 121 that constitutes the rear surface of second housing 12 is formed with second opening 122. As shown in Fig. 3, this second opening 122 is covered by second cover 16.

[0021] As shown in Fig. 4, inside the second opening 122 in the second housing 12, there are provided an outlet 34 for the fire receiving unit 30, a power cable 35, and a power switch 40. The outlet 34 is an insertion port for a plug (not shown) for supplying power to an external device of the device 100. A plug (not shown) is inserted into and removed from the outlet 34 via the second opening 122. Power is supplied from the fire receiving unit 30 to the external device connected to the plug via the outlet 34. The power cable 35 is wiring for the fire receiving unit 30 to receive power. The power switch 40 is a switch for switching the power supply to the fire receiving unit 30 between on and off.

[0022] 4, the outlet 34, the power cable 35, and the power switch 40 are provided so as to be exposed to the outside of the case 10 when the second cover 16 is removed. Therefore, with the first housing 11 and the second housing 12 closed, the user can access the outlet 34, the power cable 35, and the power switch 40 simply by removing the second cover 16. Since the worker does not need to open the case 10 to access the outlet 34, the power cable 35, and the power switch 40, operability for the worker can be improved.

[0023] A partition plate 18 is provided in the second housing 12 to separate the second housing 12. The partition plate 18 has a surface parallel to the second surface 121 and a surface extending forward from the periphery of this surface, forming a space between the partition plate 18 and the second opening 122. An outlet 34 and a power cable 35 are attached to the partition plate 18. A wiring introduction hole 19 is also formed in the partition plate 18. The wiring introduction hole 19 is a hole that connects the space in front of and behind the partition plate 18, that is, the inside and outside of the second housing 12. A cable that connects the fire receiving unit 30 arranged in the case 10 and the device arranged outside the case 10 is inserted into the wiring introduction hole 19. By providing the partition plate 18, components such as a circuit board 37 and a cable 39 (see Figs. 5 and 6) inside the case 10 are not exposed from the second opening 122 when the second cover 16 is removed. Therefore, even if the second cover 16 is opened when operating the outlet 34 and the power cable 35, it is possible to prevent an operator or object from unintentionally contacting other components in the case 10. Also, since the partition plate 18 is provided with a wiring introduction hole 19, it is possible to connect the circuit board 37 or the terminal block 32 to an external device by passing a cable connected to the circuit board 37 or the terminal block 32 through the wiring introduction hole 19. Also, by passing this cable through the wiring introduction hole 19, it is possible to prevent multiple cables connecting the fire receiving unit 30 to external devices from becoming scattered.

[0024] Fig. 5 is a diagram illustrating the inside of the first housing 11 of the device 100 according to the first embodiment. Fig. 5 shows the inside of the first housing 11 as viewed from the front. The first housing 11 and the second housing 12 are rotatably connected by a hinge 20. Fig. 5 shows the back of the operation display device 31 and the terminal block 32 shown in Fig. 2. A cable 39 is connected to the terminal block 32. A circuit board 37 of the fire receiving unit 30 is provided inside the first housing 11.

[0025] The circuit board 37 includes a circuit for controlling the operation of the operation display device 31, a circuit for processing input signals from the terminal block 32 and the operation unit 33, a power supply circuit, and a circuit for controlling signals input and output between the terminal device and the circuit board 37. A CPU is mounted on the circuit board 37 as a device for controlling the entire fire receiving unit 30. The number of circuit boards 37 and their arrangement within the case 10 are not limited to the example shown in the figure.

[0026] Fig. 6 is a diagram illustrating the inside of second housing 12 of device 100 according to embodiment 1. Fig. 6 shows the inside of second housing 12 as viewed from the front. A circuit board 37 is provided inside second housing 12, similar to first housing 11. The circuit board 37 inside first housing 11 and the circuit board 37 of second housing 12 are electrically connected by a cable 39.

[0027] Inside the second housing 12, a metal plate 21 is provided along the inner side of the second housing 12. The metal plate 21 is made of aluminum, for example. In the example of FIG. 6, the metal plate 21 is provided along the remaining three inner sides of the generally rectangular second housing 12, excluding the inner side on which the partition plate 18 is provided. A gap allowing ventilation is provided between the metal plate 21 and the inner side of the second housing 12. A heat-generating component 38 mounted on a circuit board 37 is thermally connected to a part of the metal plate 21. The heat-generating component 38 is a component that becomes hot when electricity is applied. The heat of the heat-generating component 38 is transferred to the metal plate 21 and dissipated to the air via the metal plate 21. Since the metal plate 21 functions as a heat-dissipating component, heat dissipation from the heat-generating component 38 is promoted, and the heat generation of the heat-generating component 38 can be suppressed. In addition, the metal plate 21 is provided with a gap between the metal plate 21 and the inner side of the second housing 12. Therefore, this gap functions as a heat insulating layer between the second housing 12 and the metal plate 21, and makes it possible to suppress an increase in temperature of the second housing 12 due to heat transfer from the heat-generating component .

[0028] FIG. 7 is a diagram illustrating a state in which the case 10 of the device 100 according to the first embodiment is open. The case 10 is configured by connecting the first housing 11 and the second housing 12 by the hinge 20 as described above. The open state of the case 10 refers to a state in which the first housing 11 rotates by the first angle θ around the hinge 20 in a direction away from the second housing 12. Here, the first angle θ is 90 degrees or more. When the case 10 containing the fire receiving unit 30 is opened and placed so that the second housing 12 is located on the lower side, the case 10 is configured to maintain a stationary state. In other words, the weights and arrangements of the first housing 11, the second housing 12, and the fire receiving unit 30 contained therein are determined so that the first housing 11 opened by the first angle θ does not rotate and contact the floor, and the second housing 12 does not float off the floor. When an operator opens the first housing 11 and operates the components inside the case 10, the operator can stably work on the components inside the case 10 because the first housing 11 and the second housing 12 are stationary.

[0029] Next, an example of use of the device 100 of this embodiment will be described. When constructing a fire alarm system including a terminal device such as a fire detector and a fire receiver in a building, the terminal device and the fire receiver are often not installed at the same time, and the terminal device is generally installed prior to the fire receiver. It is necessary to perform an operation test including an operation check and a setting check on the installed terminal device, but it is not possible to perform the operation test without a connected fire receiver. If a test device is prepared for the operation test, the initial cost of developing the fire alarm system will increase. In addition, if the operation test is performed after the fire receiver is installed, the amount of work in the latter stages of the construction period will increase, so an additional worker will be required, and the construction cost of the fire alarm system will increase.

[0030] The device 100 of this embodiment includes a fire receiving unit 30 equipped with an operation display device 31, and a case 10 having a transport means 13 and housing the fire receiving unit 30. Since the fire receiving unit 30 is housed in the case 10 equipped with the transport means 13, the worker can carry the fire receiving unit 30 to any location. Therefore, in a fire alarm system under construction, by bringing the device 100 to a location where a terminal device is installed, the device 100 can be connected to the installed terminal device to perform an operation test of the terminal device. The fire receiving unit 30 of the device 100 of the present invention is recognized by the terminal device as substantially the same device as a fire receiver. Therefore, by connecting to the device 100 and performing an operation test of the terminal device, the terminal device can be made to perform the same operation as when the fire receiver is connected before the fire receiver is installed in the building. In addition, the terminal device may be installed on a high ceiling, but the scaffolding that is set up during installation is generally removed after the terminal device is installed. If the operation test of the terminal device is performed after the scaffolding is removed, when the terminal device does not operate normally and needs to be reinstalled, the scaffolding needs to be reassembled, which increases the construction cost. However, by using the device 100 of this embodiment, the operation test of the terminal device can be performed while the scaffolding remains, so that the increase in the construction cost related to the reassembly of the scaffolding described above can be avoided. In this way, the device 100 of this embodiment can shorten the lead time related to the construction of the fire alarm system. Since the operation test of the terminal device can be performed without waiting for the installation of the fire receiver in the building, it is possible to avoid the need to increase the number of workers in the latter stage of the construction period described above. In addition, since there is no need to prepare a test device for the operation test, the initial cost related to the development of the fire alarm system can be suppressed. In this way, according to this embodiment, it is possible to suppress the increase in the cost of development and construction of the fire alarm system. In addition, since the worker does not need to learn how to use the test device, the increase in the burden on the worker is also suppressed.

[0031] The device 100 of this embodiment can also be used for training workers before installing a fire alarm system, or for practice in handling a fire receiver. When installing or using a fire receiver, the person installing or using it needs to learn and practice how to use it, but by using the device 100 of this embodiment, this can be easily done. Since there is no need to prepare special teaching materials for the person installing or using it, training costs can be reduced.

[0032] Embodiment 2 In this embodiment, a device 100A is described that includes a case 10A having a different shape from the case 10 of embodiment 1. In this embodiment, the differences from embodiment 1 are mainly described, and the same components of device 100A as those in embodiment 1 are denoted by the same reference numerals and description thereof is omitted.

[0033] Fig. 8 is a front view of the device 100A according to the second embodiment. Fig. 9 is a diagram showing a state in which the case 10A of the device 100A according to the second embodiment is open. The device 100A includes the case 10A and the fire receiving unit 30 housed in the case 10A. A user can carry the fire receiving unit 30 using the case 10A.

[0034] The case 10A includes a first housing 11A, a second housing 12A, and a carrying means 13A. The first housing 11A and the second housing 12A are containers with one side open. The first housing 11A and the second housing 12A are connected to each other via a hinge 20 so as to be openable and closable. When the first housing 11A and the second housing 12A are closed, the edges of the openings of the first housing 11A and the second housing 12A, which are opposed to each other, come into contact with each other. The first housing 11A and the second housing 12A are made of, for example, synthetic resin or metal. The first housing 11A and the second housing 12A may have the same shape and volume, or may have different shapes and volumes. In this embodiment, the volume of the second housing 12A is larger than the volume of the first housing 11A. The carrying means 13A is a handle attached to the upper part of the case 10. The cushioning member 17A in this embodiment has a shape that protrudes forward from the first surface 111A and extends in the width direction of the first housing 11A, and is attached to the upper part of the front surface of the first housing 11A. The left and right width of the cushioning member 17A is preferably equal to or greater than the left and right width of the operation display device 31. Note that, although an example in which the cushioning member 17A is provided only on the upper side of the operation display device 31 is shown in Fig. 8, the cushioning member 17A may be provided around the operation display device 31 other than on the upper side.

[0035] The operation display device 31, the terminal block 32, and the operation unit 33 of the fire receiving unit 30 are provided so as to be exposed to the outside of the case 10A. In the example of FIG. 8, the operation display device 31, the terminal block 32, and the operation unit 33 of the fire receiving unit 30 are exposed from a first opening 112A formed in a first surface 111A, which is the front surface of the first housing 11A. When the first housing 11A and the second housing 12A are closed, an operator can access the operation display device 31, the terminal block 32, and the operation unit 33. Since the operator does not need to open the case 10A to access the operation display device 31, the terminal block 32, and the operation unit 33, the operability of the operator can be improved.

[0036] 9, the first housing 11A and the second housing 12A are connected to each other so as to be openable and closable by a hinge 20. The first housing 11A and the second housing 12A are connected to each other by the hinge 20 in a direction in which the first housing 11A and the second housing 12A rotate horizontally.

[0037] An operation display device 31, a terminal block 32, and a circuit board 37 are provided inside the first housing 11A. Fig. 9 shows the rear of the operation display device 31 and the terminal block 32 shown in Fig. 8. A circuit board 37 is provided inside the second housing 12A. The circuit board 37 in the first housing 11A and the circuit board 37 in the second housing 12A are connected by a cable 39. In addition, the terminal block 32 and the circuit board 37 in the second housing 12A are connected by another cable 39.

[0038] A second opening 122A is formed in a second surface 121A constituting a side surface of the second housing 12A. A partition plate 18A that divides the inside of the second housing 12A is provided inside the second housing 12A. The partition plate 18A has a surface parallel to the second surface 121A and a surface extending from the periphery of this surface toward the inside of the second housing 12A, forming a space between the partition plate 18A and the second opening 122A. A power cable 35 is attached to the partition plate 18A.

[0039] The second opening 122A is covered by the second cover 16A. The second cover 16A is attached to the second housing 12A so that the second opening 122A can be opened and closed. When the second cover 16A is closed, the power cable 35 is accommodated in a space between the second cover 16A and the partition plate 18A. The second opening 122A and the partition plate 18A do not need to be provided in the case 10A. In this case, a pull-out hole for pulling out the power cable 35 is formed in the second surface 121A constituting the side surface of the second housing 12A, and the power cable 35 is pulled out from inside the case 10A. Then, a hook for locking the bundled power cable 35 may be provided on the second surface 121A of the second housing 12.

[0040] The device 100A of this embodiment may also include an outlet 34, a power switch 40, a first cover 14, a wire introduction hole 19, and a metal plate 21, as in the first embodiment. In this way, the same effects as those in the first embodiment can be obtained.

[0041] As described above, the device 100A of the present embodiment includes the fire receiving unit 30 equipped with the operation display device 31, and the case 10A having the transport means 13A and housing the fire receiving unit 30. Since the fire receiving unit 30 is housed in the case 10A equipped with the transport means 13A, the worker can carry the fire receiving unit 30 to any location. Therefore, in a fire alarm system under construction, by bringing the device 100A to a location where a terminal device is installed, the device 100A can be connected to the installed terminal device to perform an operation test of the terminal device, and the same technical effect as in the first embodiment can be obtained.

[0042] Variations. A description will be given of a modification of embodiment 1 or embodiment 2. The modification will be described using the reference numerals of the components shown in embodiment 1, but this modification can also be applied to embodiment 2 in the same manner.

[0043] When a handle is provided as the carrying means 13, instead of attaching a handle to the case 10, an extendable or foldable support may be provided to the case 10, and a handle may be attached to the support. In this case, the support and the handle constitute the carrying means 13. A shoulder strap may be provided as the carrying means 13, in which case the worker can carry the case 10 by hanging it from the shoulder. Two shoulder straps may be provided as the carrying means 13, in which case the worker can carry the case 10 on the back. Casters may be provided as the carrying means 13. In this way, the worker can move the case 10 without lifting it, improving the workability during transportation. When casters are provided as the carrying means 13, a handle or a handle provided on the support as described above may be provided in addition to the casters.

[0044] First cover 14 may be provided so as to be separable from case 10 as shown in the first embodiment, or a portion of first cover 14 may be connected to case 10. For example, first cover 14 and case 10 are connected via a hinge. In this way, first cover 14 does not separate from case 10 when first cover 14 is opened, so that loss of first cover 14 can be prevented. Similarly, a portion of second cover 16 may be connected to case 10.

[0045] A repeater that receives a signal from a terminal device such as a fire detector and transmits the received signal to the fire receiving unit 30 may be provided inside the case 10. In this way, an operation test of the fire alarm system including the repeater can be performed using the device 100. When a large-scale fire alarm system having repeaters is constructed, operation tests can be performed in order from the places where construction is completed, so that the lead time for construction of the fire alarm system can be shortened.
