Description

[Technical Field]

[0001] The present invention relates to a control device provided in an abnormality detection system that detects abnormalities. [Background technology]

[0002] 2. Description of the Related Art In an abnormality detection system, which is a system for detecting abnormalities such as fires, a predetermined type of physical quantity in a monitored area is measured by a sensor, and an abnormality is detected based on the measured physical quantity.

[0003] Some anomaly detection systems increase the reliability of anomaly detection by placing different types of anomaly detection devices in the same monitored area and determining whether or not an anomaly has occurred based on the results of the anomaly detection by each of the anomaly detection devices.

[0004] For example, Patent Document 1 describes a fire extinguishing system in which an infrared linear sensor and an infrared three-wavelength flame detector are placed in the same alert area, and when the infrared linear sensor detects a hot spot and the infrared three-wavelength flame detector detects a fire source in the direction of the hot spot, it takes action to extinguish the fire source.

[0005] [Patent Document 1] Patent Publication No. 2022-86621 Summary of the Invention [Problem to be solved by the invention]

[0006] The types of measuring devices (including combinations of multiple types of measuring devices) that measure physical quantities and that anomaly detection systems use to detect anomalies change with technological advances, etc. Generally, when different types of measuring devices are used in an anomaly detection system, the control device that performs predetermined processing using information output by the measuring device must be changed according to the type of measuring device. In this case, different control devices must be prepared according to the type of measuring device, which poses a problem of increased costs for the manufacture and inventory management of the control devices.

[0007] The present invention provides a means for reducing costs such as manufacturing and inventory management of control devices used in an anomaly detection system when there is a possibility that different types of measurement devices will be employed in the anomaly detection system. [Means for solving the problem]

[0008] The present invention provides a control device that performs predetermined processing based on information output from one or more measuring devices that measure physical quantities to detect abnormalities using sensors, and that includes a plurality of different processing systems that perform the predetermined processing according to the types of the one or more measuring devices, and an enabling means for enabling only one selected processing system from the plurality of processing systems. [Effects of the Invention]

[0009] According to the control device of the present invention, even if different types of measuring devices may be used in the anomaly detection system, there is no need to prepare different control devices corresponding to those different types of measuring devices, thereby reducing costs such as manufacturing and inventory management of the control devices.

[0011] [Embodiment] A fire extinguishing system 1 according to one embodiment of the present invention will be described below. Fig. 1 is a diagram showing the configuration of the fire extinguishing system 1. The fire extinguishing system 1 is a system that detects fires (an example of an abnormality) in a monitored area and extinguishes the fires.

[0012] In the example of Fig. 1, the monitored area is divided into two sections, section R1 and section R2, but the monitored area may be a single section or may be divided into three or more sections. However, in the following description, it is assumed that the monitored area is divided into section R1 and section R2 as shown in Fig. 1.

[0013] The fire extinguishing system 1 includes, as components corresponding to each of the multiple compartments, a detection device 11, a nozzle 12, a valve mechanism 13, and an operating device 14. The fire extinguishing system 1 also includes, as components common to the multiple compartments, a pump 15 and a control device 16.

[0014] The detection device 11 is a device (an example of a measurement device) that continuously measures a predetermined type of physical quantity that changes when a fire occurs and detects a fire by detecting the change in the physical quantity. The detection device 11 is placed in the monitored area (section R1 or section R2) to measure the physical quantity in the monitored area.

[0015] In this embodiment, the type of the detection device 11 is one of the following three types. (1) A composite detector having both a first type detector 111 and a second type detector 112 (2) A first-type single detection device having only the first-type detection device 111 (3) A second-type single detection device having only the second-type detection device 112

[0016] The first type detection device 111 is a fire detection device connected to a fire extinguishing control device 161 provided in the control device 16. On the other hand, the second type detection device 112 is a fire detection device connected to a fire receiving panel 162 provided in the control device 16.

[0017] In this application, the term "device" refers to both a single device such as (2) or (3) above, and a collection of multiple devices (detection device group) such as (1) above. Also, in this application, the term "type of device" refers to both a single device type such as "first type detection device 111" or "second type detection device 112," and a combination of multiple devices such as "first type detection device 111 and second type detection device 112."

[0018] 1 illustrates the case where the type of the detection device 11 is the above-mentioned type (1). Note that if the type of the detection device 11 is the above-mentioned type (2), the fire receiving panel 162 is not necessary.

[0019] In the event of a fire occurring, the nozzle 12 sprays a fire-extinguishing liquid in the compartment where the fire has occurred. Therefore, the nozzle 12 is disposed within the monitored area (compartment R1 or compartment R2).

[0020] The valve mechanism 13 is disposed on a supply pipe that supplies fire extinguishing liquid from the pump 15 to the nozzle 12, and opens and closes the supply pipe. Note that the valve mechanism 13 does not necessarily have to be disposed within the monitored area (compartment R1 or compartment R2).

[0021] The operating device 14 is a device that allows a user to instruct the fire extinguishing control device 161 to start or stop spraying of fire extinguishing liquid in the compartment where the fire is occurring (compartment R1 or compartment R2) when a fire occurs. Therefore, the operating device 14 is placed within the monitored area (compartment R1 or compartment R2).

[0022] However, if a terminal of a communication line drawn from the fire extinguishing control device 161 is located within the monitored area (compartment R1 or compartment R2), the user may bring the operation device 14, which is normally placed outside the monitored area, into the monitored area (compartment R1 or compartment R2) in the event of a fire, and connect it to the terminal of the communication line to communicate with the fire extinguishing control device 161. Also, if the fire extinguishing control device 161 is capable of wireless communication with the operation device 14, the user may bring the operation device 14, which is normally placed outside the monitored area, into the monitored area (compartment R1 or compartment R2) in the event of a fire, and communicate wirelessly with the fire extinguishing control device 161. In these cases, the fire extinguishing system 1 does not need to have an operation device 14 corresponding to each of the multiple compartments, and it is sufficient to have one operation device 14 that can be used in any of the compartments.

[0023] The pump 15 draws up the extinguishing liquid from a tank (not shown) storing the extinguishing liquid, applies pressure to send it to a supply pipe, and thereby pressure-feeds the extinguishing liquid toward the nozzle 12.

[0024] The pump 15, supply pipe, nozzle 12 and valve mechanism 13 constitute a fire extinguishing system for extinguishing a detected fire.

[0025] The control device 16 performs a predetermined process using the information output from the detection device 11. In this embodiment, the control device 16 is a device group including a fire extinguishing control device 161 and a fire receiving panel 162.

[0026] The fire extinguishing control device 161 has a display and a speaker, and continuously determines whether or not a fire has occurred in each of the multiple compartments based on information obtained from at least one of the first-class detection device 111 and the fire receiving panel 162. If it determines that a fire has occurred, it issues a warning sound or a warning message from the speaker to notify people in the vicinity that a fire has occurred, and displays the compartment in which the fire has occurred on the display. Furthermore, when a user operates the operation device 14 to instruct the start of spraying of fire extinguishing liquid, the fire extinguishing control device 161 controls the pump 15 and the valve mechanism 13 so that fire extinguishing liquid is sprayed from the nozzle 12 of the compartment corresponding to the operation device 14.

[0027] The fire extinguishing control device 161 performs different predetermined processes as follows in relation to the determination of whether or not a fire has occurred, depending on the type of the detection device 11.

[0028] (1) When the detection device 11 is a composite detection device having both the first type detection device 111 and the second type detection device 112, the fire extinguishing control device 161 operates in a state where there is a signal input from the first type detection device 111 (an example of a fire detection device) and a signal input from the fire receiving panel 162. In this case, when the fire extinguishing control device 161 receives a fire detection notification from the first type detection device 111 arranged in any compartment notifying that a fire has been detected, and also receives a fire detection notification from the fire receiving panel 162 notifying that a fire has been detected in that compartment, the fire extinguishing control device 161 determines that a fire has occurred in that compartment. Hereinafter, the state of the fire extinguishing control device 161 that performs the above-described processing in a state where there is a signal input from both the first type detection device 111 and the fire receiving panel 162 is referred to as the "composite detection mode."

[0029] (2) When the detection device 11 is a first-class single detection device having only the first-class detection device 111, the fire extinguishing control device 161 operates when there is a signal input from the first-class detection device 111 and there is no signal input from the fire receiving panel 162. In this case, the fire extinguishing control device 161 operates when there is a signal input from either the first-class detection device 111 or the fire receiving panel 162. When a fire detection notification is received from the first type detection device 111 arranged in a compartment notifying that a fire has been detected, it is determined that a fire has occurred in that compartment. Hereinafter, the state of the fire extinguishing control device 161 that performs the above-mentioned processing when there is a signal input from the first type detection device 111 but there is no signal input from the fire receiving panel 162 is referred to as the "first type single detection mode."

[0030] (3) When the detection device 11 is a type 2 single detection device having only the type 2 detection device 112, the fire extinguishing control device 161 operates in a state where there is no signal input from the type 1 detection device 111 and there is a signal input from the fire receiving panel 162. In this case, when the fire extinguishing control device 161 receives a fire detection notification from the fire receiving panel 162 notifying that a fire has been detected in any compartment, it determines that a fire has occurred in that compartment. Hereinafter, the state of the fire extinguishing control device 161 that performs the above-mentioned processing in a state where there is no signal input from the type 1 detection device 111 and there is a signal input from the fire receiving panel 162 is referred to as the "type 2 single detection mode."

[0031] The fire receiving panel 162 has a display and a speaker, and when it receives a fire detection notification indicating that a fire has been detected from any of the second-class detection devices 112, it issues a warning sound or a warning message from the speaker to notify people in the vicinity that a fire has occurred, and displays the compartment in which the fire has occurred on the display. Furthermore, when the fire receiving panel 162 receives a fire detection notification indicating that a fire has been detected from any of the second-class detection devices 112, it outputs a fire detection notification indicating that a fire has been detected in that compartment to the fire extinguishing control device 161, and also transmits the fire detection notification to a higher-level system (not shown).

[0032] As described above, the fire extinguishing control device 161 operates in one operation mode selected from three states (hereinafter referred to as "operation modes"): the combined detection mode, the first type single detection mode, and the second type single detection mode, depending on the type of detection device 11 included in the fire extinguishing system 1. Therefore, the fire extinguishing control device 161 includes a circuit (an example of a processing system) for operating in the combined detection mode, a circuit (an example of a processing system) for operating in the first type single detection mode, and a circuit (an example of a processing system) for operating in the second type single detection mode.

[0033] Note that, among these three circuits, parts of two or more may be used in common. For example, part of the electrical circuit constituting the circuit for operating in the combined detection mode may constitute part of the circuit for operating in the first type single detection mode.

[0034] The fire extinguishing control device 161 includes an enabling means for enabling only one selected circuit out of three circuits corresponding to the three operation modes.

[0035] 2 is a plan view of mode setting unit 1611, which is an enabling means provided in fire extinguishing control device 161. Mode setting unit 1611 is mounted on circuit board 1610 on which the above-mentioned three circuits provided in fire extinguishing control device 161 are mounted. Mode setting unit 1611 has three cutting jumpers J (an example of a member to be cut), namely, cutting jumpers J1 to J3.

[0036] FIG. 3 is a perspective view showing the outer shape of the cutting jumper J. The cutting jumper J is a bent, plate-shaped metal member having a body Ja extending in a direction along the circuit board 1610, a pair of legs Jb extending from each end of the body Ja toward the circuit board 1610, and a foot Jc extending from the lower end of the legs Jb in a direction along the circuit board 1610. Each of the pair of legs Jc is joined to a different position on the circuit board 1610. Note that the metal used to make the cutting jumper J is preferably aluminum, which can be easily cut with a cutting tool such as nippers. In the cutting jumper J illustrated in FIG. 3, a notch C is provided in the middle of the leg Jb to facilitate cutting the leg Jb.

[0037] 2 shows the mode setting unit 1611 in a state where none of the cutting jumpers J are cut off. In this state, none of the three circuits corresponding to the three operating modes are enabled.

[0038] When leg Jb of cutting jumper J1 is cut from the state shown in Figure 2, of the circuits corresponding to the three operating modes, only the circuit corresponding to the composite detection mode becomes active, and the circuits corresponding to the Type 1 single detection mode and Type 2 single detection mode become inactive.

[0039] Furthermore, when leg Jb of cutting jumper J2 is cut from the state shown in Figure 2, of the circuits corresponding to the three operating modes, only the circuit corresponding to Type 1 single detection mode becomes active, and the circuits corresponding to the combined detection mode and Type 2 single detection mode become inactive.

[0040] Furthermore, when leg Jb of cutting jumper J3 is cut from the state shown in Figure 2, of the circuits corresponding to the three operating modes, only the circuit corresponding to the Type 2 single detection mode becomes active, and the circuits corresponding to the combined detection mode and Type 1 single detection mode become inactive.

[0041] When two or more of the three cutting jumpers J are cut, all three circuits corresponding to the three operating modes are disabled.

[0042] 4 shows a state in which the detection device 11 provided in the fire extinguishing system 1 is a composite detection device having both a first type detection device 111 and a second type detection device 112, with the cutting jumper J1 disconnected. In the state shown in FIG. 4, only the circuit corresponding to the composite detection mode is enabled.

[0043] In this application, an active circuit means a state in which current flows through the circuit while the device is operating, contributing to the operation of the device, and an inactive circuit means a state in which no current flows through the circuit while the device is operating, and therefore does not contribute to the operation of the device.

[0044] The user can set the fire extinguishing control device 161 to an operating mode in which a predetermined process is performed according to the type of detection device 11 provided in the fire extinguishing system 1 by cutting one of the three cutting jumpers J.

[0045] Once the cutting jumper J is disconnected, it cannot be easily restored to its original state. Therefore, the mode setting unit 1611 irreversibly enables only one selected circuit from among multiple circuits corresponding to multiple operating modes. In this application, "irreversible" means that it is difficult to restore the original state to the extent that repair or replacement of a component is required. In other words, once a user disconnects one of the cutting jumpers J of the mode setting unit 1611 to enable only a circuit corresponding to one of the operating modes, the enabled circuit cannot be easily changed. As a result, once the operating mode of the fire extinguishing control device 161 is set, there is no inconvenience such as the user unintentionally touching the mode setting unit 1611 and switching the operating mode of the fire extinguishing control device 161.

[0046] According to the above-described fire extinguishing control device 161, it is possible to use a fire extinguishing control device 161 of the same configuration in any of a plurality of fire extinguishing systems 1 employing different types of detection devices 11. Therefore, costs for manufacturing the fire extinguishing control device 161, inventory management, etc. are reduced compared to when fire extinguishing control devices 161 of different configurations must be prepared depending on the type of detection device 11 employed in the fire extinguishing system 1.

[0047] [Variations] The above-described embodiment is one embodiment of the present invention, and various modifications can be made within the scope of the technical concept of the present invention. These modifications are shown below. Note that two or more of the modifications shown below may be combined as appropriate.

[0048] (1) In the above-described embodiment, the predetermined processing that the fire extinguishing control device 161 performs based on the information output from the detection device 11 is one example, and may be modified in various ways.

[0049] For example, in the above-described embodiment, the fire extinguishing control device 161 controls the pump 15 and the valve mechanism 13 to start spraying fire extinguishing liquid in response to a user's operation on the operating device 14 to start spraying fire extinguishing liquid, but if the fire extinguishing control device 161 determines that a fire has occurred in any compartment and then a predetermined time has passed without receiving an instruction from the operating device 14 to start spraying fire extinguishing liquid in that compartment, the fire extinguishing control device 161 may automatically control the pump 15 and the valve mechanism 13 to start spraying fire extinguishing liquid in the compartment where it has been determined that a fire has occurred.

[0050] (2) The types of detection device 11 described in the above embodiment are examples, and the types of detection device 11 may be changed in various ways. For example, if there are three types of single detection device 11, the types of detection device 11 may be two or more of the following seven types: A composite detection device having a first type detection device, a second type detection device, and a third type detection device A composite detection device having a first type detection device and a second type detection device A composite detection device having a first-type detection device and a third-type detection device A composite detection device having a second type detection device and a third type detection device A single detector having only a first type detector Single detector having only type 2 detector Single detector having only type 2 detector

[0051] (3) In the above-described embodiment, the combination of the cutting jumpers J that are disconnected (disconnected state) among the multiple cutting jumpers J provided in the mode setting unit 1611 and the circuit corresponding to the enabled operating mode are associated as follows:

[0052] None of the cutting jumpers J1 to J3 are cut: All circuits for the combined detection mode, Type 1 single detection mode, and Type 2 single detection mode are disabled. Cutting jumper J1 is disconnected, and cutting jumpers J2 and J3 are not disconnected: The combined detection mode circuit is enabled. Cutting jumper J2 is disconnected, and cutting jumpers J1 and J3 are not disconnected: The Type 1 single detection mode circuit is enabled. Cutting jumper J3 is disconnected, and cutting jumpers J1 and J2 are not disconnected: The Type 2 single detection mode circuit is enabled. Two or more of the cutting jumpers J1 to J3 are disconnected: All circuits for the combined detection mode, Type 1 single detection mode, and Type 2 single detection mode are disabled.

[0053] The above-described correspondence between the disconnection state and the operation mode is merely an example, and various other correspondences may be adopted. For example, the following correspondences may be adopted.

[0054] None of the cutting jumpers J1 to J3 are cut: All circuits for the combined detection mode, Type 1 single detection mode, and Type 2 single detection mode are disabled. One of the cutting jumpers J1 to J3 is disconnected and the other two are not disconnected: All circuits for the combined detection mode, Type 1 single detection mode, and Type 2 single detection mode are disabled. Cutting jumpers J2 and J3 are disconnected, and cutting jumper J1 is not disconnected: The combined detection mode circuit is enabled. Cutting jumpers J1 and J3 are disconnected, and cutting jumper J2 is not disconnected: The Type 1 single detection mode circuit is enabled. Cutting jumpers J1 and J2 are disconnected, and cutting jumper J3 is not disconnected: The Type 2 single detection mode circuit is enabled. All cutting jumpers J1 to J3 are disconnected: All circuits for the combined detection mode, Type 1 single detection mode, and Type 2 single detection mode are disabled.

[0055] When the correspondence described in the embodiment or the correspondence according to the above-mentioned modified example is adopted, once a circuit of one of the operating modes is enabled, disconnecting an uncut cutting jumper will not enable a circuit of another operating mode.

[0056] For example, when the correspondence described in the embodiment is adopted, when none of the cutting jumpers J1 to J3 are disconnected, the circuit for the combined detection mode is enabled. Subsequently, whether one or both of the remaining cutting jumpers J2 and J3 are disconnected, all of the circuits for the combined detection mode, the first-type single detection mode, and the second-type single detection mode are disabled. Therefore, a control device 16 in which the circuit for the combined detection mode is enabled cannot be easily changed to a control device 16 in which the circuit for the first-type single detection mode is enabled or a control device 16 in which the circuit for the second-type single detection mode is enabled.

[0057] Similarly, when the correspondence according to the above modification is adopted, when cutting jumpers J2 and J3 are disconnected from a state in which none of cutting jumpers J1 to J3 are disconnected, the circuit for the combined detection mode is enabled. Note that in the process of disconnecting these cutting jumpers J2 and J3, for example, a state in which only cutting jumper J2 is disconnected or a state in which only cutting jumper J3 is disconnected may occur, but in either of these states, all circuits for the combined detection mode, Type 1 single detection mode, and Type 2 single detection mode remain disabled.

[0058] When the cutting jumpers J2 and J3 are disconnected and the combined detection mode circuit is enabled, if the undisconnected cutting jumper J1 is disconnected, all of the circuits for the combined detection mode, the first type single detection mode, and the second type single detection mode are disabled. Therefore, a control device 16 in which the combined detection mode circuit is enabled cannot be easily changed to a control device 16 in which the first type single detection mode circuit is enabled or a control device 16 in which the second type single detection mode circuit is enabled.

[0059] As described above, if a combination of cut jumpers J is associated with a circuit corresponding to an enabled operating mode so that when one or more of the uncut cutting jumpers J are cut while a circuit for any operating mode is enabled, the circuits for all operating modes are disabled. This is suitable for cases where there is a constraint that an operating mode once set in the control device 16 in, for example, a factory, should not be easily changed at, for example, the installation site.

[0060] If the above-mentioned constraints were not present, the correspondence between the combination of disconnected cutting jumpers J (disconnected state) and the circuits corresponding to the enabled operation modes could be changed in many different ways. For example, the mode setting unit 1611 may include only cutting jumper J1 and cutting jumper J2, and the following correspondence may be adopted.

[0061] Both cutting jumpers J1 and J2 are not cut: All circuits for the combined detection mode, Type 1 single detection mode, and Type 2 single detection mode are disabled. Cutting jumpers J1 and J2 are disconnected: Combined detection mode circuitry is enabled Cutting jumper J1 is disconnected and cutting jumper J2 is not disconnected: The Type 1 single detection mode circuit is enabled. Cutting jumper J2 is disconnected and cutting jumper J1 is not disconnected: The second type single detection mode circuit is enabled.

[0062] (4) In the above-described embodiment, the mode setting unit 1611 includes a cutting jumper J to irreversibly enable only one selected circuit among the multiple circuits, and the user sets the operation mode of the fire extinguishing control device 161 by cutting the cutting jumper J. The configuration that should be adopted by the mode setting unit 1611 to irreversibly enable only one selected circuit among the multiple circuits is not limited to the configuration using the cutting jumper J.

[0063] For example, a configuration may be adopted in which the mode setting unit 1611 has multiple pinholes instead of multiple cutting jumpers J, and the user can close an open circuit by inserting a metal pin into one of the pinholes so that it is completely buried, thereby enabling only one selected circuit from the multiple circuits. In this case, the pin once inserted into the pinhole cannot be easily removed, so the mode setting unit 1611 can irreversibly enable the circuit.

[0064] (5) In the above-described embodiment, the mode setting unit 1611 is configured to irreversibly enable the circuit. However, if there are sufficient measures to prevent accidents such as a user unintentionally touching the mode setting unit 1611 and switching the operating mode of the fire extinguishing control device 161, the mode setting unit 1611 may be configured with a normal jumper switch or the like, so that the circuit can be reversibly enabled.

[0065] (6) In the above-described embodiment, the circuit enabled by the mode setting unit 1611 is a circuit for operating the fire extinguishing control device 161 in an operating mode corresponding to the type of detection device 11, but the type of circuit enabled by the mode setting unit 1611 is not limited to this.

[0066] For example, in addition to the circuitry for the fire extinguishing control device 161 to perform predetermined processing based on information output from the detection device 11, the mode setting unit 1611 may enable or disable circuits according to functions that the fire extinguishing control device 161 can optionally implement.

[0067] For example, if the fire extinguishing control device 161 can detachably mount a speaker, the mode setting unit 1611 may enable a circuit for sound generation processing (an example of additional processing) that is disabled, or disable a circuit for sound generation processing that is enabled. In this case, the user can enable or disable the circuit for sound generation processing by cutting or not cutting a cutting jumper J corresponding to the circuit for sound generation processing, among the multiple cutting jumpers J that the mode setting unit 1611 has.

[0068] (7) In the above-described embodiment, the detection means for detecting an abnormality based on a physical quantity measured by a sensor (or a group of sensors) in a monitored area is provided in a device (detection device 11) that includes a sensor (or a group of sensors), but this is not limited to this. For example, instead of the detection device 11, the fire extinguishing system 1 may include a measurement device that includes a sensor (or a group of sensors) but does not perform abnormality detection processing, and the measurement device may output the measurement results to the control device 16, and the control device 16 may detect an abnormality based on the measurement results received from the measurement device.

[0069] (8) In the above-described embodiment, the abnormality detected by the detection device 11 is a fire. However, the detection device 11 may also detect abnormalities other than fire, such as the leakage of harmful gases or the intrusion of a suspicious person.

[0070] (9) In the above-described embodiment, the fire extinguishing control device 161 is provided with a processing system for executing each of a plurality of predetermined processes, such as a process for operating in the combined detection mode, a process for operating in the first type single detection mode, and a process for operating in the second type single detection mode, each of which includes a circuit corresponding to each of the plurality of processes, i.e., dedicated hardware. The processing system that the fire extinguishing control device 161 is provided with for executing each of the plurality of processes is not limited to dedicated hardware.

[0071] For example, the fire extinguishing control device 161 may be configured to include a processor capable of performing general-purpose data processing, a memory that stores programs corresponding to multiple operating modes, and a circuit that outputs a signal (hereinafter referred to as a "mode signal") to the processor according to the state of the mode setting unit 1611 set by the user, and the processor reads out and executes the program corresponding to the operating mode indicated by the mode signal from the memory.

[0072] (10) There may be cases where the operating mode that should be enabled in the control device 16 does not match the operating mode that is actually enabled in the control device 16 by the mode setting unit 1611, for example, due to an operator's mistake in using the mode setting unit 1611 (such as accidentally cutting the cutting jumper J).

[0073] For example, when the control device 16 is shipped from the factory, the operating mode is set correctly by the mode setting unit 1611, but a situation may arise in which a maintenance worker or the like accidentally cuts an uncut cutting jumper J at the installation site of the control device 16, thereby disabling all operating modes.

[0074] In such a case, an inconvenience may occur in that the control device 16 does not perform the intended operation when an abnormality is detected. The control device 16 may be provided with a mechanism for reducing or preventing the occurrence of such inconvenience.

[0075] For example, when the control device 16 changes the circuit (processing system) of the operating mode that is enabled in response to a change in the state of the mode setting unit 1611, the control device 16 may detect the change and perform predetermined processing such as sounding an alarm, displaying and sounding an alarm message, etc., to prompt the user (such as the administrator of the fire extinguishing system 1) to confirm that the operating mode set by the mode setting unit 1611 is correct.

[0076] Furthermore, for example, when the control device 16 is shipped from the factory, information indicating the operation mode to be set in the control device 16 (hereinafter referred to as "mode information") may be stored, and if the operation mode of the circuit that the control device 16 activates according to the state of the mode setting unit 1611 does not match the operation mode indicated by the stored mode information, the control device 16 may notify the user of the incorrect setting of the operation mode by sounding an alarm, displaying and sounding an alarm message, or may perform predetermined processing such as automatically shutting down the control device itself.
