Description

  The present invention relates to an alarm system that outputs an emergency earthquake warning to an alarm device that detects an abnormality such as a fire or a gas leak and issues an alarm.

  2. Description of the Related Art Conventionally, an alarm device that detects an abnormality such as a fire or a gas leak in a house and issues an alarm is widespread. Of these, the residential disaster alarm is called the house alarm.

  In such a house alarm, a sensor unit and an alarm unit are integrated in the house alarm, and when a fire is detected by the sensor unit, a fire alarm is issued by a voice message or the like from the alarm unit. Since fire monitoring and alarming can be performed by a single living arrestor without the need for a receiving facility or the like, installation is simple and inexpensive, and it has become widespread along with the mandatory installation in ordinary houses.

  In addition, by communicating between multiple house alarms, if a fire alarm is issued by any house alarm, other house alarms will also be linked, and an interlocking house alarm system will be proposed. Have been.

  In such a house alarm system, when a fire is detected by the house alarm, the interlocking house alarm that detected the fire may, for example, say, "Please confirm that the Woo Woo fire alarm has been activated." Outputs voice messages. When an alarm is issued by a living arrest device, the alarm is stopped by operating an alarm stop switch provided on the housing arrest device.

  On the other hand, a dedicated emergency earthquake early warning device that receives an emergency earthquake early warning transmitted when an earthquake of a predetermined size or more occurs and issues an alarm is known. The Earthquake Early Warning System, for example, selects a specific FM radio broadcast and is in a reception standby state. After the Emergency Earthquake Early Warning emits a predetermined chime twice, for example, "Emergency Earthquake Broadcasting. Beware of strong shaking." The automatic chime sound is played twice, for example, the first chime sound is analyzed, an emergency earthquake early warning signal is detected, and the broadcast reproduction operation is started. The occurrence is notified.

JP 2007-094719 A Japanese Utility Model Registration No. 3154579 JP 2009-244937 A International Publication No. 2009/118951 JP 2009-244937 A JP 2008-217435 A JP-A-62-173600 JP 2008-03543A JP 2010-026545 A JP 2007-128221 A JP 2009-048665 A

  However, in such a conventional emergency earthquake early warning device, the broadcast of the emergency earthquake early warning can be heard only within a range where sound from the emergency earthquake early warning device can be heard, and the emergency earthquake early warning device is installed in each room. It is necessary, but there are problems such as high cost and the need to secure installation space in various places.

  In addition, since it is basically an FM radio receiver, the radio wave conditions are poor in some rooms and FM radio waves cannot be received with sufficient intensity. is there.

  An object of the present invention is to provide an alarm system capable of knowing occurrence of an earthquake even in a room where an earthquake early warning device is not installed or in a place where the FM broadcast reception environment is not good, in cooperation with an alarm device. And

The present invention relates to an alarm system including an earthquake warning device and an alarm device,
The earthquake early warning device can set in advance a prohibition mode that prohibits the self-reporting of the information indicating the emergency earthquake early warning. In addition to notifying the information indicating the early warning, transmitting the device event signal indicating the emergency earthquake early warning to the alarm device, and when detecting the emergency earthquake early warning signal in the state where the prohibition mode is set, the information indicating the emergency earthquake early warning is transmitted. Without alerting itself, it sends a device event signal indicating an emergency earthquake warning to the alarm device, and if an event signal indicating an abnormality is received from the alarm device, notifies the abnormality,
The alarm device, when detecting an abnormality in the alert area, notifies the abnormality, transmits an event signal indicating the abnormality to the earthquake early warning device, and further receives a device event signal indicating the emergency earthquake early warning from the earthquake early warning device. It is characterized in that it is possible to report information indicating an earthquake early warning.

The alarm device can set in advance a prohibition mode for prohibiting the notification of the emergency earthquake early warning. When the device event signal indicating the emergency earthquake early warning is received in the state where the information indicating the emergency earthquake early warning is set in the prohibited mode, the information indicating the emergency earthquake early warning is not notified .

  According to the present invention, for example, an emergency earthquake early warning by FM broadcasting is received by a residential monitoring / warning system composed of one or a plurality of alarm devices for detecting an abnormality such as a fire and outputting an abnormality alarm. By linking the Earthquake Early Warning device to be reproduced, when the Earthquake Early Warning device receives an emergency earthquake early warning by FM broadcast, an event signal indicating the emergency earthquake early warning is transmitted to the alarm device in the alarm system, and each received An alarm can notify the occurrence of an earthquake.For example, just by installing an earthquake warning device in one place in a house, an earthquake occurrence can be notified in another room where the alarm device is installed. It requires only a minimum number of devices, so the cost is low, and if an alarm is installed, even if you are in another room, you can know the occurrence of an earthquake and respond immediately.

  Further, when an alarm such as a fire is detected by an alarm device and an alarm is issued, an event signal indicating the abnormality is also sent to the earthquake early warning device, and the earthquake early warning device can also notify the abnormalities such as a fire occurrence.

  Also, since the earthquake early warning device is linked to the alarm, the area that can be notified by the earthquake early warning device is expanded, so even if the area to be notified is outside the area that can be notified by the alarm unit provided in the earthquake early warning device. It is only necessary to be within the alerting area of the alarm device. Therefore, the seismic alert device can be installed in a location with good radio wave conditions that can receive FM broadcasting irrespective of its own alerting area. Earthquake early warnings can be reliably received to notify the occurrence of an earthquake from the earthquake early warning device itself and the associated alarm, and even if the earthquake early warning device is installed in a place where no alarm is installed, the location Alerts you of abnormalities such as fire alarms.

  Also, for example, for an alarm installed in the same room as the earthquake early warning device, setting the mode to prohibit the reporting of event information on the earthquake early warning device side such as emergency earthquake early warning can be set, so that both the earthquake early warning device and the alarm , It is possible to eliminate the difficulty of hearing due to the notification of the occurrence of an earthquake, and to suppress unnecessary power consumption by setting a prohibition mode for an alarm device that does not need to output a notification.

  In addition, by operating the test switch provided on the earthquake early warning device, an event signal (device event signal) indicating the emergency earthquake early warning test can be sent to the alarm device to easily perform the emergency earthquake early warning test. It is possible to easily perform a notification test of an abnormal alarm with the earthquake early warning device. Also, an alarm stop event signal can be sent to stop the alarm of the alarm device.

Explanatory drawing showing a house equipped with a monitoring system according to the present invention, which is composed of an emergency earthquake alert device and a house alarm Explanatory drawing showing the appearance of a wireless dwelling device according to the present invention. FIG. 2 is a block diagram showing an embodiment of a dwelling alarm and an emergency earthquake warning device provided in the alarm system of FIG. 1. Explanatory diagram showing formats of an event signal and a device event signal used in the present embodiment. Flow chart showing the monitoring process by the dwelling unit in FIG. The flowchart which showed the monitoring processing of the dwelling device following FIG. Flowchart showing the processing by the emergency earthquake alert device of FIG.

  FIG. 1 is an explanatory diagram showing an installation state of an alarm system according to the present invention in a house. In the example of FIG. 1, a wireless dwelling device that detects and alerts a fire in each of the guard areas of the living room, kitchen, children's room, master bedroom, and staircase provided in the house 24 (for housing) Fire alarms) 10-1 to 10-6 are installed, and an earthquake early warning device 25 is installed in a corridor with a good FM radio wave environment. Here, the emergency earthquake alert device 25 corresponds to the earthquake alert device described in the claims.

  The dwelling alarms 10-1 to 10-6 have a function of transmitting and receiving event signals to and from each other by radio, and monitor each guard area. Here, six units monitor fires of the entire house. If a fire should occur in the kitchen of the house 24, the dwelling alarm 10-2 detects the fire and starts an alarm. Detecting this fire and starting an alarm is referred to as "alarming" in a living arrestor. When the house alarm 10-2 issues an alarm, the house alarm 10-2 functions as an interlocking source, and a fire occurs to the other house alarms 10-1, 10-3 to 10-6 to be interlocked. Is transmitted wirelessly. When receiving an event signal indicating the occurrence of a fire from the interlocking source housing alarm 10-2, the other dwelling alarms 10-1, 10-3 to 10-6 serve as interlocking destinations by an alarm sound and an alarm display. Alarm operation.

  The self-detected events detected by the residential police (called alarm events) include not only the above-mentioned fire occurrence, but also fire recovery, alarm stop operation, emergency earthquake early warning and emergency earthquake early warning test stop, etc. Various types of event signals from alarm devices and devices are also included. These will be described later.

  As the alarm operation of the living arrestor 10-2 that is the interlocking source, for example, an alarm sound is output by a voice message such as “Woo woo, the fire alarm has been activated, please confirm”. On the other hand, the linked alarm devices 10-1 and 10-3 to 10-6 output an alarm sound by voice message such as "Please confirm that a different fire alarm device has been activated."

  In addition, as a display (referred to as an alarm display) accompanying an alarm of the dwelling unit 10-2 that is the interlocking source, for example, an LED 22 (described later) is turned on. On the other hand, the LED 22 is blinked in the linked home alarm devices 10-1, 10-3 to 10-6. This makes it possible to distinguish the alarm display by the LED 22 between the interlocking source alarm and the interlocking destination alarm.

  Note that the linked LED 22 may blink and the linked LED 22 may blink, or the same LED 22 may blink or blink and light up for both the linked alarm and the linked alarm. Alternatively, for example, a two-color display may be provided in which a red LED and a yellow LED are provided, the linked source drives the red LED, and the linked destination drives the yellow LED. Of course, a two-color LED that can emit both red and yellow light can be adopted by integrating the two LEDs.

  When the alarm stop switch 20 (described later) is operated in a state where the dwelling alarms 10-1 to 10-6 are emitting an alarm sound, a process of stopping the alarm sound and the alarm display is performed.

  At this time, for example, when the alarm stop operation is performed on the living arresting device 10-2 that is the interlocking source, all of the resident arresting devices 10-1 to 10-6 (hereinafter, the resident arresting devices 10-1 to 10- 6 are collectively referred to without discriminating, the alarm (alarm sound output and / or alarm display output) of the house alarm 10 is stopped, and the house alarms 10-1, 10-3 to 10 which are linked destinations are stopped. When the alarm stop operation is performed in any of −6, the alarm of the dwelling alarm 10-2 is not stopped, and the alarms of the dwelling alarms 10-1, 10-3 to 10-6 are stopped. To In addition, the emergency earthquake warning device 25 described below may be configured to perform the alarm stop operation of the alarm device in the same manner.

  The emergency earthquake early warning device 25 detects an emergency earthquake early warning signal by, for example, FM broadcast as its own event, reproduces and outputs the event, and transmits an event signal indicating the emergency earthquake early warning to the dwelling device 10. Here, the event detected by the earthquake early warning device 25 corresponds to the device event described in the claims. The event detected by the emergency earthquake early warning device includes, in addition to the above-mentioned emergency earthquake early warning signal reception, operation of the operation unit, reception of an event signal from the living arrest device 10, and the like. An event signal transmitted by the emergency earthquake warning device is called a device event signal.

  The emergency earthquake early warning device 25 detects and reproduces and outputs an emergency earthquake early warning signal by FM broadcasting, and wirelessly transmits an event signal indicating the emergency earthquake early warning to the alarm device 10. Here, the emergency earthquake bulletin by the FM broadcast is to repeat twice "(two chime sounds) emergency earthquake bulletin. Please beware of strong shaking." When the first chime sound signal is analyzed and the detection of the emergency earthquake early warning signal is detected and detected, the mode switches from the standby mode to the standby mode to the playback operation, and the following "Earthquake early warning. Beware of strong shaking." Output from the speaker at the set volume.

  With the installation of the emergency earthquake early warning device 25, the house policing device 10 of the present embodiment, when receiving a device event signal indicating the emergency earthquake early warning from the emergency earthquake early warning device 25, outputs information indicating the emergency earthquake early warning as a voice message. Output. A voice message indicating information indicating the earthquake early warning is, for example, "Peepy earthquake early warning. Beware of strong shaking."

  When receiving an event signal indicating a fire from the dwelling alarm 10, the emergency earthquake warning device 25 outputs an alarm sound indicating a fire. The fire alarm sound of the emergency earthquake warning device 25 is, for example, a voice message such as “Woooo fire alarm has been activated, please check”. Further, the emergency earthquake warning device 25 may display the fire by lighting, blinking, blinking, etc. of the LED together with the fire alarm sound.

If the event signal contains an identification code (ID) for identifying a living politician, the emergency earthquake warning device 25 decodes the same, and the voice message content that indicates which of the municipal politics 10 has issued a fire alarm is provided. And display content. As described above, the interlocking type house alarm system does not have a dedicated receiver, but in this case, the emergency earthquake early warning device 25 is used as a device that plays a role of a fire receiver in a so-called fire alarm system. It is possible to collectively manage the fire monitoring network of the house alarm.

  The emergency earthquake early warning device 25 is provided with a test switch. When the test switch is operated, a device event signal indicating an emergency earthquake early warning test is transmitted. Then, the information indicating the emergency earthquake early warning test is notified by a voice message or the like from the house policing device 10 that receives this. For example, a voice message notifying the information indicating the emergency earthquake early warning test is "PPP emergency earthquake early warning test.

  Further, when the test switch of the emergency earthquake early warning device 25 is operated, a test for fire alarm notification of the emergency earthquake early warning device 25 itself is performed, and a voice test message such as “Woooo fire test” is output.

  That is, in the present embodiment, when the test switch of the emergency earthquake early warning device 25 is operated, the device event signal indicating the emergency earthquake early warning test is transmitted to the house policing device 10 to test the emergency earthquake early warning information, and The earthquake warning device 25 itself performs a fire notification test. By doing in this way, the emergency earthquake early warning device 25 can perform the emergency earthquake early warning interlocking to the house alarm 10 and the fire alarm notification test of the emergency earthquake early warning device 25 at a time.

  The execution of the test using the test switch is not limited to this mode. When the test switch is operated, the housing alarm 10 transmits a device event signal indicating a fire alarm test to perform the fire alarm test, and the The device 25 itself may perform a fire alarm notification test, or the device 25 may transmit a device event signal indicating an emergency earthquake early warning test to the housing policing device 10 to test the emergency earthquake early warning device. A test report of the earthquake early warning may be performed. At these times, a response event signal is returned from the house policing device that has received the device event signal transmitted from the emergency earthquake early warning device, and after receiving the response, a test report is issued from the emergency earthquake early warning device 25 itself. You may do it. In this way, the two-way communication test is performed simultaneously between the earthquake early warning device 25 and the dwelling alarm 10, and more reliable operation can be guaranteed.

  Of course, the fire test and the emergency earthquake early warning test may be selected and performed by pressing the test switch. Further, a test switch for instructing a fire test and a test switch for instructing an emergency earthquake early warning test may be separately provided.

  If the emergency earthquake early warning device 25 is installed in the same place as any of the dwelling alarms 10, the emergency earthquake early warning is output from both voices, making it difficult to hear. Therefore, in the present embodiment, the prohibition mode for prohibiting the output of the emergency earthquake early warning to the house alarm 10 can be set by a dip switch or the like, and the same place as the emergency earthquake early warning device 25 (the place where the alarm and the notification range overlap) By setting the prohibition mode for the dwelling devices installed in (1), even if an event signal indicating the emergency earthquake alert is received from the emergency earthquake alert device 25, the information indicating the emergency earthquake alert is not output. I do.

The prohibition mode setting function can be similarly used when a plurality of house alarms are installed in the same place.

  As described above, the prohibition mode setting function may be provided on the house policing device side. However, in general, it is assumed that the number of units installed on the house policing device is larger than the number of emergency earthquake early warning devices. May be provided in the emergency earthquake alerting device 25 in consideration of the overall cost and the like. This eliminates the need to install a prohibition mode setting function in a large number of installed home alarms, reduces the overall cost of system equipment, and provides an emergency earthquake warning device when checking whether a prohibition mode is set. It is effective to prevent the operation from becoming complicated, for example, by performing only the above operation.

  In addition, when considering the overlap alerting of the Earthquake Early Warning System and the house alarm, and the overlapping alerting of the house alarms, both the house alarm and the Earthquake Early Warning System must be equipped with a prohibition mode setting function. You may make it able to set each according to a situation etc. At this time, naturally, when a plurality of emergency earthquake early warning devices are installed at the same place, it is possible to make settings so as to avoid overlapping notification between the emergency earthquake early warning devices.

  Of course, even in an installation situation in which an alarm or a notification sound is output in duplicate, it is not always necessary to use the prohibition mode setting, and it is appropriately selected and set at the discretion of the user.

  The wireless communication unit 30 is provided with a transmission circuit 42 and a reception circuit 44 so that event signals can be wirelessly transmitted and received between the other dwelling devices 10-2 to 10-6. Device event signal can be received. As the wireless communication unit 30, in Japan, for example, STD-30 (a radio equipment standard for a low power security system radio station) or STD-T67 known as a standard for a specific low power radio station in the 400 MHz band, for example. (Standard specifications for radio equipment for specific low-power radio station telemeters, telecontrol, and data transmission).

  Of course, the wireless communication unit 30 has a content that conforms to the standard of the assigned radio station in a region other than Japan.

  In the memory 32 as a storage unit, a serial number 48 which is a serial number indicating the order of the event signal, a transmission source code 50 which is an ID (own identifier) for identifying each dwelling arrestor, and as shown in FIG. A group code 52 for configuring an interlocking group that performs an interlocking alarm with the installed dwelling devices 10-1 to 10-6 is stored.

  The serial number 48 is for managing relay processing of an event signal between alarm devices, particularly in wireless communication, but a detailed description thereof is omitted because it is not directly related to the present invention.

  As the transmission source code 50, for example, a 26-bit code code is used, and the serial number of the dwelling arrestor is used so as not to overlap with any of the dwelling arrestors provided in Japan.

  The group code 52 is a code that is commonly set for a plurality of dwelling arrestors constituting an interlocking group. The group code included in an event signal from another dwelling arrestor received by the wireless communication unit 30 is registered in the memory 32. This event signal is processed as a valid signal when it matches the group code 52, so that it does not need to be connected to an alarm device that is installed in a nearby house or the like and belongs to another group that does not require interlocking. Can be avoided.

  The group code 52 does not necessarily have to be the same code for each dwelling horn, and it is possible to judge whether the group to which the self belongs and the group to which the other dwelling units belong are the same by performing an operation or the like based on this code. Anything is fine.

  The sensor section 34 is provided with a smoke detection section 16 that detects smoke and outputs a signal. As described above, the sensor unit 34 may be provided with a temperature detecting element such as a thermistor for detecting a temperature due to a fire or various elements for detecting a change in other physical phenomena due to a fire, instead of the smoke detecting unit 16. .

  The notification unit 36 is provided with a speaker 56 for outputting an alarm sound and the like and the LED 22 for displaying an alarm and the like. The speaker 56 outputs various voice messages, alarm sounds, and the like held by itself from a voice synthesis circuit unit (not shown) via an amplifier (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, and lighting. A buzzer or the like may be used instead of the speaker 56. Further, instead of the LED 22, a two-color LED, a liquid crystal display, or the like may be provided. Of course, an LED and a liquid crystal display may be provided side by side.

  The operation unit 38 is provided with an alarm stop switch 20. The alarm stop switch 20 functions as an alarm stop switch only when a warning sound of a fire or a failure is output from the notification unit 36 by the speaker 56 or when an alarm is displayed by the LED 22. For example, when the alarm stop switch 20 is operated during the alarm indicating the interlocking source, the alarm sound and the alarm display are stopped. On the other hand, when the alarm stop switch 20 is operated during the alarm indicating the interlocking destination, the alarm sound is stopped, but the alarm sound is stopped. An alarm stop process such as stopping the display or stopping after a predetermined time is performed.

  On the other hand, in the normal monitoring state in which the alarm indicating the interlocking source or the interlocking destination is not performed, the alarm stop switch 20 functions as an inspection switch. When the alarm stop switch 20 is operated in this state, a predetermined self-inspection operation is performed. A voice message or the like indicating the inspection result is output from the speaker 56 of the notification unit 36.

  When the alarm stop switch 20 is operated during a fault alarm, a predetermined self-check operation may be performed to notify the result, and then the fault alarm stop process may be performed. With this configuration, for example, the failure alarm stop processing is performed after rechecking the sensor failure or the like, so that the user can more clearly recognize the failure state. If the failure state has been resolved at this time, for example, a message such as "the failure has been resolved" may be output, and the process may shift to failure stop processing.

  Further, the operation unit 38 is provided with a mode switch 21. The mode switch 21 is a dip switch or the like provided on the back of the main body or the like, and can turn on / off the notification prohibition mode of the emergency earthquake early warning. When the prohibition mode is set (turned on) by turning on the mode switch 21, even if a device event signal indicating the emergency earthquake alert is received from the emergency earthquake alert device 25, the information indicating the emergency earthquake alert is output from the notification unit 36. Absent.

  By using this function, for example, when a house alarm is installed in the room where the emergency earthquake warning device is installed, or when multiple house alarms are installed in the same room, etc. , Information can be output only to a predetermined device in the room, so that redundant information output by a plurality of devices can be avoided, and in this case, for example, battery consumption of a prohibited residential alarm is suppressed. And the like.

  The battery power supply 40 uses, for example, a lithium battery or an alkaline dry battery having a predetermined number of cells, and has a battery capacity of, for example, 10 due to a reduction in power consumption of the entire circuit unit including the wireless communication unit 30 in the house alarm 10-1. It guarantees a battery life of years.

  The processor 28 is provided with functions of an event detection unit 58, a transmission processing unit 60, a reception processing unit 62, an alarm processing unit 64, and an emergency earthquake early warning processing unit 66 as functions realized by executing a program.

  The event detection unit 58 detects events such as detection of an abnormality (here, a fire) by the sensor unit 34, stop of an alarm by the operation unit 38, and recovery from an abnormality in which the abnormality detection of the sensor unit 34 is stopped. Further, the event detection unit 58 outputs the event contents obtained as a result of decoding the event signals from the other dwelling devices 10-2 to 10-6 and the device event signal from the emergency earthquake early warning device 25 via the reception processing unit 62. To detect.

  The transmission processing unit 60 indicates a detection event when the event detection unit 58 detects its own event such as an abnormality detection by the sensor unit 34, an alarm stop by the operation unit 38, or an abnormality recovery such that the abnormality detection of the sensor unit 34 is stopped. The event signal is transmitted from the wireless communication unit 30 to the linked home alarm or the emergency earthquake alert device. The reception processing unit 62 receives and decodes the event signals from the other dwelling devices 10-2 to 10-6 and the device event signal from the emergency earthquake alert device 25 via the wireless communication unit 30.

  The type of the device event signal may be a signal indicating an emergency earthquake early warning or a fire alarm or the like of the dwelling unit 10 that is stopped by operating an operation unit 78 (described later) provided in the emergency earthquake early warning device 25. There are a signal indicating an alarm stop, a signal indicating an emergency earthquake early warning test by operating a test switch 88 (described later) provided on the operation unit 78 of the emergency earthquake early warning device 25, and the like.

  In addition, when the house policing device 10 receives the device event signal indicating the alarm stoppage transmitted from the wireless communication unit 80 (described later) of the emergency earthquake warning device 25 by operating the test switch 88, if The alarm may be continued, and the alarm may be stopped if the link destination is set.

  When the event detection unit 58 detects a fire as its own abnormality, the alarm processing unit 64 outputs an alarm sound indicating the interlocking source from the speaker 56, and drives the LED 22 to perform an alarm display indicating the interlocking source. Then, an event signal indicating a fire is transmitted to the other dwelling alarms 10-2 to 10-6 and the emergency earthquake alert device 25.

  More specifically, when the event detection unit 58 detects a fire based on the smoke detection signal of the smoke detection unit 16 provided in the sensor unit 34, the alarm processing unit 64 determines the link source from the speaker 56 of the notification unit 36. In addition to repeatedly outputting an alarm sound such as "Woo Woo Fire", the LED 22 is turned on to display an alarm indicating the interlocking source, and further, an event signal indicating a fire is transmitted via the transmission processing unit 64 and the transmission circuit 42. The transmission circuit 42 of the wireless communication unit 30 transmits the signal from the antenna 31 to the other dwelling devices 10-2 to 10-6 and the emergency earthquake alert device 25.

  Further, the alarm processing unit 64 receives an event signal indicating a fire from any of the other dwelling devices 10-2 to 10-6 by the receiving circuit 44 of the wireless communication unit 30, and is enabled by the reception processing unit 62. At the same time, an alarm sound indicating the link destination, for example, "Woooo another fire alarm has been activated, please check" is repeatedly output from the speaker 56 of the notification unit 36, and at the same time, the LED 22 flashes and the link destination is blinked. Is displayed. When an event signal indicating a fire from the dwelling alarm 10-1 is received by the emergency earthquake early warning device 25, the emergency earthquake early warning device 25 uses the speaker 74 (described later) to check, for example, "Woo fire alarm has been activated. Please "voice message is output.

  Here, the event detection unit 58 detects a sensor failure and a low battery failure. The detection of the sensor failure is performed by reading the smoke detection signal output from the smoke detector 16 of the sensor unit 34 by A / D conversion at a predetermined measurement time interval T1, for example, T1 = 1 second interval, and holding it in the buffer area of the memory 32. Then, for example, at every predetermined time interval T2 = 10 minutes, an average value of the detection data for 10 minutes held in the buffer area of the memory 32 is obtained, and this average value is used as a predetermined reference level (referred to as a zero point level). When it falls below, it is determined that the output of the sensor unit 34 is faulty, for example, that the output is stopped.

  The reason why the 10-minute average value of the smoke density detection signal is lower than the zero point level as described above may be due to a failure such as disconnection of the light receiving element provided in the smoke detection unit 16 or stoppage of the light receiving amplifier. Is high. Note that, even when a temperature detecting element such as a thermistor is provided in the sensor section 16, a sensor failure can be similarly detected by various processes.

  The low battery failure is detected by reading the power supply voltage of the battery power supply 40 by A / D conversion at a predetermined measurement time interval T3, for example, T3 = 4 time intervals, and comparing it with a predetermined threshold voltage. The battery failure is determined, and the low battery failure is determined when the determination of the low battery failure continues for a predetermined number of times.

  When the event detection unit 58 detects a sensor failure or a low battery failure, the alarm processing unit 64 outputs a sensor failure or a low battery failure warning indicating an interlocking source by an alarm sound from the speaker 56 of the notification unit 36 and the display of the LED 22. Let it. Further, the alarm processing unit 64 transmits an event signal indicating a sensor failure or a low battery failure to the other dwelling alarms 10-2 to 10-6 and the emergency earthquake alert device 25 to send dwelling alarms 10-2 to 10-6. Then, the emergency earthquake early warning device 25 is caused to issue a sensor failure or low battery failure warning indicating a link destination by a warning sound and / or display.

  Further, the alarm processing unit 64 notifies when an event signal indicating a sensor failure or a low battery failure is received from any of the other dwelling alarms 10-2 to 10-6 via the reception circuit 44 and the reception processing unit 62. The alarm sound from the speaker 56 of the unit 36 and the display of the LED 22 output a sensor failure or low battery failure warning indicating the link destination.

  When the event detection unit 58 detects a sensor failure, the alarm processing unit 64 continuously outputs, for example, a “pip failure” a plurality of times as an alarm sound of a sensor failure indicating an interlocking source (failure source) from the speaker 56 of the notification unit 36. At the same time, the LED 22 is turned on, for example, and thereafter, the process of outputting the sound of “pip failure” and displaying the LED 22 a plurality of times is repeated at regular intervals.

  The alarm processing unit 64 transmits an event signal indicating a sensor failure to the other dwelling alarms 10-2 to 10-6 and the emergency earthquake early warning device 25 via the transmission processing unit 60 and the transmission circuit 42, thereby interlocking. A sensor failure alarm indicating the destination is output. At this time, for example, an alarm sound such as "Another beep alarm is out of order" or "A beep alarm is out of order" is output, and a blinking display different from the interlocking source is performed.

  If the event signal includes an identification code (ID) for identifying a living arrest device, the emergency seismic alert device 25 decodes the code to determine which of the mortar devices 10 has failed. It can be displayed content. This applies to the low battery failure described below. Although the interlocking type house alarm system does not have a dedicated receiver, in this case, the emergency earthquake warning device 25 can be used as a device that plays the role of a fire receiver in a so-called fire alarm system. In addition, it becomes possible to collectively manage the monitoring network of the dwelling equipment.

  When the event detection unit 58 detects a low battery failure, the alarm processing unit 64 outputs a low battery failure warning sound indicating the interlocking source (failure source) from the speaker 56 of the notification unit 36, for example, "Pip battery dead". The LED 22 is turned on, for example, while outputting a plurality of times continuously, and thereafter, a process of outputting the sound of “battery dead” and displaying the LED 22 a plurality of times is repeated at regular intervals.

  In addition, the alarm processing unit 64 transmits an event signal indicating a low battery failure to the other dwelling alarms 10-2 to 10-6 and the emergency earthquake warning device 25, thereby generating a low battery failure alarm indicating an interlocking destination as an alarm sound. Output “beep alarm is out of battery” or “beep alarm is out of battery” and make a blinking display different from the linked source.

  Further, the alarm processing unit 64 detects the operation of the alarm stop switch 20 during the output of the fire alarm sound indicating the interlocking source or the fire alarm sound indicating the interlocking destination, or detects the operation of the other house alarms 10-2 to 10-6. When an event signal indicating the stop of the alarm or the reception of the device event signal from any of the emergency earthquake early warning devices 25 is detected, the output of the voice message from the speaker 56 and the fire alarm by the alarm display of the LED 22 are stopped. At this time, the alarm display by the LED 22 may be stopped after a predetermined time has elapsed. During the fire alarm indicating the interlocking source, at least the output of the alarm sound may be continued even if the event signal indicating the stop of the alarm or the device event signal is received.

  Further, when the alarm processing unit 64 detects the alarm stop operation of the alarm stop switch 20 provided in the operation unit 38 during the output of the sensor failure or the low battery failure alarm indicating the interlocking source, the alarm processing unit 64 emits an alarm sound indicating the interlocking source. An event signal indicating that the stop is performed after the obstacle display is continued for a predetermined time and stops, and further the other house alarms 10-2 to 10-6 and the emergency earthquake warning device 25 that are outputting the obstacle alarm indicating the link destination are instructed to stop the alarm. Is transmitted to stop the alarm sound and the display of the failure of the dwelling alarms 10-2 to 10-6 and the emergency earthquake warning device 25.

  When receiving the device event signal indicating the emergency earthquake alert from the emergency earthquake alert device 25 via the reception circuit 44 and the reception processing unit 62, the emergency earthquake alert processing unit 66 outputs a voice message as information indicating the emergency earthquake alert. The information is output from the speaker 56 of the notification unit 36 and the LED 22 is turned on, blinks, or blinks.

  When receiving the device event signal indicating the emergency earthquake early warning test from the emergency earthquake early warning device 25, the emergency earthquake early warning processing unit 66 outputs a voice message indicating the emergency earthquake early warning test from the speaker 56 of the notifying unit 36. The LED 22 is turned on, blinks, or blinks.

  Furthermore, when the prohibition mode for prohibiting the output of the information indicating the emergency earthquake alert is set by the setting ON operation of the mode switch 21, the emergency earthquake alert processor 66 transmits the emergency earthquake alert from the emergency earthquake alert device 25. Even if the device event signal shown is received, the voice message output of the information indicating the emergency earthquake early warning test is not performed.

  The output prohibition of the voice message by the mode switch 21 may be set for the emergency earthquake alert.

  When a prohibition mode setting switch is provided in the operation unit 78 of the emergency earthquake alert device 25 described later, the fire alarm output from the emergency earthquake alert device 25 may be inhibited by setting the inhibit mode switch.

Even when the voice message or the sound output is prohibited, only the display may be performed, and conversely, only the display may be prohibited. Further, this may be specified separately.
That is, the output prohibition setting can be appropriately selected and set for the emergency earthquake early warning and the emergency earthquake early warning test, and the sound output and the display output.

  With this configuration, the notification method can be selectively set according to the type of the event for which the notification is output, and an appropriate notification pattern can be set according to the user's request and the installation status of the device. , Easy to use.

  Next, the earthquake early warning device 25 will be described. The earthquake early warning device 25 includes a processor 68, an FM receiver 70 having an antenna 71, an audio amplifier 72, a speaker 74, a display unit 76, an operation unit 78, and a wireless communication unit 80. As functions to be realized by execution, there are provided an emergency earthquake early warning analysis unit 90, a device event detection unit 92, a transmission control unit 94, a reception control unit 96, and an alarm control unit 98.

  The FM receiving unit 70 tunes the tuner to the FM station selected by the operation of the operation unit 78, receives the FM broadcast radio wave via the FM antenna 71, demodulates the signal as an audio signal, and outputs the demodulated sound signal. The operation of the audio amplifying unit 72 is stopped in the standby state, and therefore, the reproduction and output of the FM broadcast received from the speaker 74 is not performed. When an emergency earthquake early warning signal is detected by the analysis processing of the processor 68, the audio amplifier 72 is switched to the operating state. At this time, the broadcast content of the emergency earthquake early warning reproduced and output from the FM receiver 70 is transmitted via the amplifier 72. Output from the speaker 74. The display unit 76 performs a display required for FM broadcast reception, such as a reception standby display, an emergency earthquake early warning reception display, a tuning frequency display, and a fire alarm display.

  The wireless communication unit 80 is provided with a transmission circuit 84 and a reception circuit 86 so that the device event signal can be wirelessly transmitted from the antenna 82 to the dwelling device 10. As in the case of the domestic policing device 10-1, the wireless communication unit 80 conforms to STD-30 or STD-T67 known as a standard for a 400 MHz band specific low power radio station, for example, in Japan. It has a configuration.

  The memory (not shown), like the memory 32 of the dwelling equipment 10-1, transmits a serial number, which is a serial number indicating the order of the event signals, and an ID (own identifier) for identifying the emergency earthquake alert device. An original code and a group code for forming an interlocking group are stored.

  The device event detection unit 92 provided in the processor 68 detects the reception of the earthquake early warning signal based on the analysis processing results of the two chime sounds flowing first in the emergency earthquake early warning by the emergency earthquake early warning analysis unit 90. The alarm control unit 98 operates the audio amplification unit 72 for a predetermined time to cause the speaker 74 to reproduce and output the earthquake early warning. The analysis of the chime sound of the emergency earthquake alert by the emergency earthquake alert analysis unit 90 is performed by, for example, the vector correlation method described in Patent Document 3.

  The device event detection unit 92 detects a device event such as the reception of an emergency earthquake early warning signal by the emergency earthquake early warning analysis unit 90 and the reception of an event signal from the dwelling alarm 10 by the reception control unit 96. When the device event detection unit 92 detects the reception of the earthquake early warning signal, the transmission control unit 94 transmits a device event signal indicating the emergency earthquake early warning to the house policing device 10 and outputs the information indicating the emergency earthquake early warning. . The reception control unit 96 receives an event signal from the dwelling alarm 10 via the reception circuit 86.

  When the device event detection unit 92 detects reception of an event signal indicating a fire from any of the dwelling alarms 10, the alarm processing unit 98 operates the sound amplification unit 72 to output an alarm sound from the speaker 74. At the same time, the display unit 76 displays a fire. Further, the alarm processing section 98 stops the alarm sound and the fire display when the device event detection section 92 receives an event signal indicating a fire recovery or an alarm stop from any one of the house alarms 10.

  The operation unit 78 is provided with a test switch 88. When the test switch 88 is operated, the operation of the test switch 88 is detected by the device event detection unit 92. Based on the operation, the transmission control unit 94 transmits a device event signal indicating an emergency earthquake early warning test to the dwelling alarm 10 side to perform a test. Perform the notification operation.

  Further, the alarm control section 98 may cause the speaker 74 and the display section 76 to perform a test notification of an alarm sound indicating a fire and a display based on the operation detection of the test switch 88 by the device event detection section 92.

  Further, a mode switch for setting the prohibition of the fire alarm is provided on the operation unit 78, and when the emergency earthquake warning device 25 is installed at the same place as the alarm device, or when the fire alarm interlocking notification is not required, the mode switch is set to the mode switch. Notification of a fire alarm may be prohibited by operation.

  The power source of the earthquake early warning device 25 may be a commercial AC power source or a battery. Further, another dedicated power supply may be used.

  FIG. 4 is an explanatory diagram showing the format of the event signal and the device event signal used for the linked alarm in this embodiment. In FIG. 4, the event signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54.

  The serial number 48 is a serial number indicating the order of the event signal, and is incremented by one every time the event signal is transmitted. Further, the serial number 48 is generated asynchronously by each of the dwelling alarm 10 and the emergency earthquake alert device 25. The serial number 48 is for managing the relay processing of the event signal and the like mainly in the wireless communication between the dwelling alarm 10 and the emergency earthquake alert device 25, but is not directly related to the present invention, and therefore will be described in detail. Is omitted.

  The transmission source code 50 is, for example, a 26-bit code, and uses the serial number of the dwelling alarm 10 and the earthquake early warning device 25 and the like. The group code 52 is, for example, an 8-bit code, and the same group code is set for, for example, the dwelling devices 10-1 to 10-6 and the emergency earthquake alert device 25 of FIG.

  As the group code 52, besides setting the same group code for the same group of dwelling arrestors, for example, a reference code common to the dwelling arrestors constituting a predetermined group, and a transmission code unique to each dwelling arrestor The group code may be different for each dwelling device obtained from the operation with the original code.

The event code 54 is a code representing the content of an event such as a fire or gas leak (for example, in the case of a house alarm having a gas leak alarm or a gas leak detection function). In the present embodiment, a 4-bit code is used. For example, 0001 = fire 0010 = gas leak 0011 = alarm stop 0100 = recovery 0101 = sensor failure 0110 = low battery failure 0111 = emergency earthquake alert 1000 = emergency earthquake alert test. Here, 0000 is used without event detection, for example, for periodic notification.

  By increasing the number of bits of the event code 42 to 5 bits or 6 bits, more event contents can be represented. For example, the recovery event code may be divided into fire recovery and failure recovery. In an alarm device that detects an abnormality other than a fire, the above-mentioned 0001 may be replaced with an abnormal event to be detected, or the type of an abnormal event to be detected may be added to, for example, the above. In this way, for example, alarm devices having different types of abnormalities to be detected can be mixed in the same group.

  FIG. 5 and FIG. 6 are flowcharts showing an example of the monitoring process in the dwelling device 10-1 of FIG. The same processing is performed for the other dwelling devices 10-2 to 10-6. In FIG. 5, when the power supply from the battery power supply 40 of the house alarm 10-1 is started, in step S1, initialization, self-diagnosis, and reading of various settings including the presence or absence of the setting of the prohibition mode are executed. If not, the process proceeds to step S2 to monitor the fire. If the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, a fire is determined in step S2 and the process proceeds to step S3, where an event signal including a serial number, a transmission source code, a group code, and an event code indicating a fire. Is transmitted wirelessly to the other house alarm and the emergency earthquake alerting device 25, and in step S4, the linking source is indicated by an alarm sound such as a voice message or a buzzer sound from the speaker 56 of the notifying unit 36 and an alarm display by turning on the LED 22. Outputs a fire alarm.

  Subsequently, in step S5, it is determined whether or not there is a fire recovery in which the smoke detection signal from the sensor unit 34 is reduced and the fire state is eliminated, and if the fire recovery is determined, the serial number, the transmission source code, and the group code are determined in step S6. After transmitting an event signal including an event code indicating a fire recovery to the other dwelling arrestors and the emergency earthquake alerting device 25, the link source based on the alarm sound from the speaker 56 and the alarm display by turning on the LED 22 is shown in step S7. Stop the fire alarm. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed.

  Subsequently, it is determined in step S8 whether or not the alarm stop switch 20 has been operated. If the switch operation has been determined, it is determined in step S9 whether or not an alarm has been issued. If it is determined in step S9 that an alarm is being performed, the process proceeds to step S10, in which an event signal including a serial number, a transmission source code, a group code, and an event code indicating that the alarm is stopped is transmitted to the other dwelling equipment and the emergency earthquake warning device 25. Then, the process proceeds to step S11, in which the output of the alarm sound indicating the interlocking source from the speaker 56 is stopped, and the alarm display by turning on the LED 22 is turned off. Note that the LED 22 may be turned off after a predetermined time has elapsed.

  When it is determined in step S9 that the alarm is not being performed, a predetermined inspection operation is performed and the result is reported, but is not shown.

  Subsequently, the process proceeds to step S12 in FIG. 6, and it is determined whether or not an event signal indicating a fire from another house alarm has been received. If it is determined that an event signal indicating a fire has been received from another house alarm, the process proceeds to step S13, where an alarm sound is output from the speaker 56 as a fire alarm indicating a link destination, and an alarm is displayed by blinking the LED 22.

  Next, in step S14, it is determined whether or not an event signal indicating fire recovery has been received from another dwelling unit, and if an event signal indicating fire recovery has been received, the process proceeds to step S15 and is performed as an alarm of a link destination. The output of the alarm sound from the speaker 56 and the display of the alarm by the blinking of the LED 22 are stopped.

  Next, in step S16, it is checked whether or not an event signal indicating an alarm stop from another dwelling arrestor or a device event signal indicating an alarm stop from the emergency earthquake warning device 25 has been received. If it is determined that the event signal has been received, the process proceeds to step S17 to determine the presence or absence of an alarm. If it is determined that the alarm is being performed, the process proceeds to step S18 to stop the output of the alarm sound as the link destination and stop the alarm display.

  Subsequently, in step S19, it is determined whether or not the prohibition mode has been set for the emergency earthquake flash report. If the prohibition mode has not been set, the process proceeds to step S20 to check whether or not an event signal indicating the emergency earthquake flash report has been received. When it is determined that the device event signal indicating the emergency earthquake early warning from 25 has been received, an emergency earthquake early warning message is output from the speaker 56 of the notification unit 36 in step S21, and at the same time, the LED 22 is turned on, for example.

  If it is determined in step S19 that the emergency earthquake early warning prohibition mode has been set, steps S20 and S21 are skipped, and no emergency earthquake notification message is output even if it is determined that a device event signal indicating the emergency earthquake early warning has been received. This is a case where the house alarm 10-1 is installed in the same room as the earthquake early warning device 25 as shown in FIG. Steps S19 and S20 may be interchanged.

  Subsequently, the process proceeds to step S22 to check whether an event signal indicating the emergency earthquake early warning test has been received. If it is determined that the event signal indicating the emergency earthquake early warning test has been received, a test message for the emergency earthquake early warning is notified in step S23. The signal is output from the speaker 56 of the unit 36, and at the same time, the LED 22 is turned on, for example. The above processing is repeated until an operation stop instruction due to power off is determined.

  In the flowcharts of FIGS. 5 and 6, the process of stopping the notification of the emergency earthquake early warning or the emergency earthquake early warning test by operating the test switch 88 provided in the operation unit 78 of the emergency earthquake early warning device 25 is omitted. It is only necessary to determine whether or not a device event signal indicating the stop of the notification has been received during the notification of the flash report or the earthquake early warning test, and stop the notification when the device event signal has been received.

  Also, it is determined whether or not the alarm stop switch 20 has been operated during the notification of the emergency earthquake early warning or the emergency earthquake early warning test, and if the operation has been performed, the alarm is stopped (or the notification is stopped) to the other house alarms and the emergency earthquake early warning device. Can be transmitted, and the notification by another alarm device or the earthquake early warning device can be stopped.

  FIG. 7 is a flowchart showing a processing example of the emergency earthquake alert device 25 shown in FIG. In FIG. 7, when the power of the emergency earthquake early warning device 25 is turned on, initialization and self-diagnosis are performed in step S31, and if there is no error, the process proceeds to step S32 to perform a tuning process of the FM station by the tuning operation of the operation unit 78. .

  Subsequently, the process proceeds to the reception standby operation of step S33. In the reception standby operation, the FM receiver 70 is operated to receive and reproduce the FM broadcast radio wave, but the operation of the audio amplifier 72 is stopped and the broadcast from the speaker 74 is not being broadcast.

  Subsequently, in step S34, the presence or absence of the chime sound of the emergency earthquake bulletin is determined through the analysis processing of the emergency earthquake bulletin analysis unit 90. When the chime sound reception is determined, the process proceeds to step S35, in which the voice amplifier 72 is operated. The broadcast of the emergency earthquake bulletin received at that time is output from the speaker 74 at a sufficiently large volume.

  Next, in step S36, the transmission circuit 84 of the wireless communication unit 80 is operated to output a device event signal indicating the emergency earthquake warning to the dwelling device 10. Subsequently, in step S37, after elapse of a predetermined time, the process proceeds to step S38, in which the operation of the audio amplification unit 72 is stopped, thereby stopping the output of the broadcast sound.

  Note that, when the notification stop instruction from the operation unit 78 is detected during the output of the emergency earthquake early warning broadcast sound from the speaker 74, the output of the emergency earthquake early warning broadcast sound is interrupted (not shown).

  Subsequently, the process proceeds to step S39, in which it is determined whether or not an event signal indicating a fire has been received from any of the dwelling alarms 10. If it is determined in step S39 that an event signal indicating a fire has been received from any of the dwelling alarms 10, the process proceeds to step S40, in which the speaker 74 and the display unit 76 output a fire alarm with an alarm sound and an alarm display.

  Next, in step S41, together with the presence or absence of an alarm stop instruction by operating the operation unit 78, it is checked whether or not an event signal indicating fire recovery or an event signal indicating an alarm stop has been received from any of the dwelling alarms 10, If it is determined that an instruction from the operation or an event signal indicating a fire recovery or an event signal indicating an alarm stop has been received, the process proceeds to step S42 to determine the presence or absence of an alarm. Stop the display. When the alarm is stopped based on the operation instruction of the operation unit 78, a device event signal indicating the stop of the alarm is output from the transmission circuit of the wireless communication unit 80 to the dwelling alarm 10 (not shown). The above processing is repeated until an operation stop instruction due to power-off is determined in step S44.

  Although the above embodiment has been described with reference to an example of a house alarm which detects a fire and issues an alarm, a gas leak alarm, a CO alarm, an alarm system in which various security alarms are arranged, and various types of such alarm systems. The present invention can be similarly applied to an alarm system in which the alarm devices are mixed and arranged.

  Further, as another embodiment of the emergency earthquake alert device, a function of a house alarm is provided in the emergency earthquake alert device, and an alarm such as a fire is detected by the emergency earthquake alert device, and an alarm is issued as an interlocking source. An event signal may be transmitted to an alarm to be linked.

  In addition, the alarms do not necessarily have to be linked with each other, but may be any as long as a predetermined alarm can link with the emergency earthquake early warning device. Some alarms may be linked and other alarms may not be linked. Furthermore, it does not prevent that there is only one alarm device. On the other hand, a plurality of emergency earthquake alert devices may be provided. At this time, the emergency earthquake warning devices may be configured to be able to cooperate with each other.

  Further, the respective linkages between the alarm device and the earthquake early warning device may not be based on wireless communication, but may be based on wired communication, or may be based on a mixture of wired and wireless.

  Further, the operation means shown as the alarm stop switch 20 and the test switch 88 in the above embodiment is not necessarily a switch, but may be a device for instructing an alarm history output by external communication using a remote control device or the like. Any means or method may be applied. The same applies to the dip switch for setting the prohibition mode and other switches provided on the operation unit 78 of the emergency earthquake alert device 25.

  In addition, it is not possible to prohibit the alarm output function of house alarms (fire alarms for houses) according to the standard. However, if an appropriate alarm other than the house alarm is used, the alarm on the alarm side will be disabled. A mode setting function for prohibition can be provided. By doing so, for example, instead of outputting an abnormality (e.g., a fire in the case of a house alarm) alarm from the emergency earthquake early warning device 25, an abnormal alarm from an alarm device installed near the emergency earthquake early warning device 25 is output. Can be taken as a pattern to prohibit.

  In addition, the interlocking output of the abnormal alarm (fire alarm or the like) from the house police to the earthquake early warning device may be performed only by the display. For example, a house alarm alone is sufficient for sound alarm output such as a buzzer sound and a voice message, but when it is desired to enhance the visual notification effect of an abnormality using a flashlight or the like that consumes a large amount of power, a commercial power supply is required. The use of a flashlight or other display device in an emergency earthquake warning device that requires a relatively low need to reduce power consumption due to the use of a dedicated power supply or the It may be operated to enhance the effect of display notification.

  Further, the flowchart in the above-described embodiment describes a schematic example of the processing, and the order of the processing is not limited to this. In addition, a delay time can be provided between each process or between processes as necessary, or another determination can be inserted.

  In addition, the processor of each device described in the above embodiment can replace some or all of its functions with another unit using, for example, wired logic. Other electrical and functional components, including the processor, can be integrated as appropriate.

  Further, the emergency earthquake early warning device may directly receive the emergency earthquake early warning of FM broadcast as in the above-described embodiment, or may receive the emergency earthquake early warning indirectly through another device or facility.

  In addition, “received”, “not received”, “received”, “determined reception”, etc. described in the above embodiment also determine whether the received signal is recognized as valid. Contains.

  Also, depending on the standard of the alarm device, the display by the LED in the above embodiment may not be recognized as an “alarm”, but in the present invention, regardless of whether or not it is included in the “alarm” in the standard, the alarm display , Display accompanying an alarm, or simply display. Any display means may be used as long as the object of the present invention can be achieved. The display unit may be provided separately from the alarm device.

 Also, the display units of the emergency earthquake early warning device 25 and the house alarm 10 (alarm device) may be provided with an abnormal (fire in the above embodiment) alarm display unit and an emergency earthquake early warning display unit, respectively. good.

  Further, in the above-described embodiment, the dwelling alarm operated by a battery power supply is taken as an example.

  In addition, the above embodiment can be applied not only to houses but also to alarms for various uses such as buildings and offices.

  Further, the above embodiment takes an example in which the sensor unit and the alarm output processing unit are integrally provided in the alarm device. However, as another embodiment, an alarm device in which the sensor unit and the alarm output processing unit are separated is used. There may be.
