Description

The present invention relates to an alarm system that outputs an Earthquake Early Warning to an alarm that detects and warns of an abnormality such as a fire or a gas leak.

Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in houses have become widespread. Of these, residential fire alarms are called residential alarms.

In such a residential alarm, a sensor unit and an alarm unit are integrally provided in the residential alarm system, and when a fire is detected by the sensor unit, the alarm unit issues a fire alarm by voice message or the like. Since the fire alarm can be monitored and alarmed by itself without the need for receiving equipment, it is easy to install and inexpensive, and it has become widespread due to the mandatory installation in general houses.

We also propose an interlocking smoke detector system that, when a fire alarm is issued by any smoke detector by communicating between multiple smoke detectors, the other smoke detectors also give an interlocking alarm. Has been done.

In such a Smoke detector system, when a fire is detected by the Smoke detector, the interlocking Smoke detector that detected the fire says, for example, "Woo Woo fire alarm has been activated. Please check." I am trying to output a voice message. When an alarm is given by the Smoke Detector, the alarm is stopped by operating the alarm stop switch provided on the Smoke Detector.

On the other hand, there is known a dedicated earthquake early warning device that receives an earthquake early warning transmitted when an earthquake of a predetermined scale or larger occurs and issues an alarm. For example, the Earthquake Early Warning device is in a reception standby state by selecting a specific FM radio broadcast, and after the Earthquake Early Warning makes a predetermined chime sound twice, for example, "Earthquake early warning. Be wary of strong shaking." For example, the first chime sound is analyzed, the Earthquake Early Warning signal is detected, the broadcast playback operation is activated, and the automatic sound following the chime sound is output at a loud volume from the speaker to cause an earthquake. I try to notify you of the occurrence.

JP-A-2007-094719 Utility Model Registration No. 3154579 JP-A-2009-244937 International Publication No. 2009/118951 JP-A-2009-244937 Japanese Unexamined Patent Publication No. 2008-217435 Japanese Unexamined Patent Publication No. 62-173600 Japanese Unexamined Patent Publication No. 2008-035423 Japanese Unexamined Patent Publication No. 2010-026545 JP-A-2007-128221 Japanese Unexamined Patent Publication No. 2009-048665 Japanese Unexamined Patent Publication No. 01-197900 JP-A-2009-218707

However, with such a conventional Earthquake Early Warning device, the Earthquake Early Warning broadcast can be heard only within the range where the sound from the Earthquake Early Warning device can be heard, and the 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, depending on the room, the radio wave condition may be poor and the FM radio wave may not be received with sufficient strength, and even if it is installed in such a place, it may not function effectively. is there.

An object of the present invention is to provide an alarm system that makes it possible to know the 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 early warning device and an alarm device.
The Earthquake Early Warning device can set in advance a prohibition mode that prohibits itself from notifying information indicating the Earthquake Early Warning, and when an Earthquake Early Warning signal by broadcasting is detected without the prohibition mode set, an Earthquake Early Warning occurs. In addition to notifying information indicating the Earthquake Early Warning, a device event signal indicating the Earthquake Early Warning is transmitted to the alarm, and if an Earthquake Early Warning signal is detected while the prohibition mode is set, the information indicating the Earthquake Early Warning is displayed. It is characterized in that it transmits an earthquake early warning device event signal to an alarm device without notifying itself, and further notifies an abnormality when an event signal indicating an abnormality is received from the alarm device.

The alarm notifies the abnormality when it detects an abnormality in the warning area, transmits an event signal indicating the abnormality to the earthquake early warning device, and further receives an event signal indicating an earthquake early warning from the earthquake early warning device. It is possible to set in advance whether or not to notify the information indicating the Earthquake Early Warning.

According to the present invention, for example, an earthquake early warning by FM broadcasting is received by a residential monitoring / alarm system composed of one or a plurality of alarms that detect an abnormality such as a fire and output an abnormality alarm. By linking the earthquake early warning device to be reproduced, when the earthquake early warning device receives the earthquake early warning by FM broadcasting, an event signal indicating the earthquake early warning is transmitted to the alarm device in the alarm system, and each received one. An earthquake early warning device can be notified from an alarm device. For example, if an earthquake early warning device is installed in one place of a house, an earthquake early warning device can be notified in another room where an earthquake early warning device is installed. Since the number of earthquakes is minimal, the cost is low, and if an alarm is installed, it is possible to know the occurrence of an earthquake and respond immediately even if you are in another room.

When an alarm device detects an abnormality such as a fire and gives an alarm, an event signal indicating the abnormality is sent to the earthquake early warning device, and the earthquake early warning device can also notify the abnormality such as a fire.

In addition, since the earthquake early warning device is linked to the alarm device, the notification area of the earthquake early warning device is expanded, so even if the notification target area is outside the notification area provided by the notification unit provided in the earthquake early warning device. It suffices if it is within the area where the alarm can be notified. Therefore, the earthquake early warning device can be installed in a place with good radio wave conditions where FM broadcasting can be received well regardless of its own area, and it is an emergency by FM broadcasting. It is possible to reliably receive the earthquake early warning and notify the occurrence of an earthquake from the earthquake early warning device itself and the linked alarm device, and even if the earthquake early warning device is installed in a place where the alarm device is not installed, that place. It is possible to notify an abnormality such as a fire alarm with.

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

In addition, by operating the test switch provided on the Earthquake Early Warning device, an event signal (device event signal) indicating the Earthquake Early Warning test can be sent to the alarm to easily perform the Earthquake Early Warning test, and at the same time. An abnormality alarm notification test can be easily performed with an earthquake early warning device. It is also possible to send an event signal to stop the alarm to stop the alarm of the alarm.

Explanatory drawing which showed the format of the event signal and the apparatus event signal used in this embodiment. Flow chart showing the monitoring process by the Smoke Detector in FIG. A flowchart showing the monitoring process of the Smoke Detector following FIG. Flow chart showing processing by the Earthquake Early Warning device of FIG.

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

Smoke detectors 10-1 to 10-6 have a function of transmitting and receiving event signals wirelessly to and from each other, and monitor each warning area. Here, six units are used to monitor fires in the entire house. If a fire breaks out in the kitchen of the house 24, the Smoke Detector 10-2 detects the fire and starts an alarm. Detecting this fire and starting an alarm is called "alarming" in the Smoke Detector. When Smoke Detector 10-2 issues a report, Smoke Detector 10-2 functions as an interlocking source, and a fire breaks out against other Smoke Detectors 10-1, 10-3 to 10-6 that are interlocking destinations. The event signal indicating is transmitted wirelessly. When the other Smoke Detectors 10-1, 10-3 to 10-6 receive an event signal indicating a fire from the interlocking Smoke Detector 10-2, they can be linked by an alarm sound and an alarm display. Alarm operation is performed.

The self-events (called alarm events) detected by the resident police include not only the above-mentioned fire occurrence, but also fire recovery, alarm stop operation, suspension of Earthquake Early Warning and Earthquake Early Warning test, and others. It also includes the reception of various event signals from the alarms and devices of. These will be described later.

As the alarm operation of the Smoke Detector 10-2, which is the interlocking source, for example, an alarm sound is output by a voice message such as "Woo Woo fire alarm has been activated. Please check." On the other hand, the interlocking destination Smoke Detectors 10-1, 10-3 to 10-6 output an alarm sound with a voice message such as "Woo, another fire alarm has been activated. Please check."

Further, as a display (referred to as an alarm display) associated with the alarm of the Smoke Detector 10-2, which is the interlocking source, for example, LED 22 (described later) is turned on. On the other hand, in the interlocking destination Smoke Detector 10-1, 10-3 to 10-6, the LED 22 blinks. This makes it possible to distinguish between the alarm display by the LED 22 in the interlocking source alarm and the interlocking destination alarm.

The interlocking source LED 22 may be blinking and the interlocking destination LED 22 may be blinking, or the interlocking source alarm and the interlocking destination alarm may be blinking, blinking, or lighting display of the same LED 22. Further, for example, a two-color display may be provided in which a red LED and a yellow LED are provided, the interlocking source drives the red LED, and the interlocking destination drives the yellow LED. Of course, a two-color LED capable of emitting both red and yellow can be adopted by integrating the two LEDs.

If the alarm stop switch 20 (described later) is operated while the Smoke Detectors 10-1 to 10-6 are emitting an alarm sound, the alarm sound and the alarm display are stopped.

At this time, for example, when the alarm stop operation is performed by the Smoke Detector 10-2, which is the interlocking source, all the Smoke Detectors 10-1 to 10-6 (hereinafter, Smoke Detectors 10-1 to 10-). When 6 is generically referred to without distinction, the alarm (alarm sound output and / or alarm display output) of the Smoke Detector 10) is stopped, and the interlocking destination Smoke Detector 10-1, 10-3 to 10 If the alarm stop operation is performed in any of -6, the alarm of Smoke Detector 10-2 will not be stopped, but the alarm of Smoke Detector 10-1, 10-3 to 10-6 will be stopped. To. Further, the earthquake early warning device 25, which will be described next, may also be able to perform the alarm stop operation of the alarm device in the same manner.

The Earthquake Early Warning device 25 detects, for example, an Earthquake Early Warning signal by FM broadcasting as its own event, reproduces and outputs it, and transmits an event signal indicating the Earthquake Early Warning to the Smoke Detector 10. Here, the event detected by the Earthquake Early Warning device 25 corresponds to the device event described in the claims. Events detected by the Earthquake Early Warning device include, in addition to the above-mentioned Earthquake Early Warning signal reception, operation of the operation unit, event signal reception from the Smoke Detector 10, and the like. Further, the event signal transmitted by the Earthquake Early Warning device is called a device event signal.

The Earthquake Early Warning device 25 detects an Earthquake Early Warning signal by FM broadcasting, reproduces and outputs it, and wirelessly transmits an event signal indicating the Earthquake Early Warning to the alarm device 10. Here, the Earthquake Early Warning by FM broadcasting is designed to repeat "(Chime sound twice) Earthquake Early Warning. Please be careful of strong shaking." Therefore, the Earthquake Early Warning device 25, for example, When the reception of the Earthquake Early Warning signal is judged and detected by analyzing the signal of the first chime sound, the reception standby state is switched to the playback operation, and the following "Earthquake Early Warning. Be wary of strong shaking." Output at the set volume from the speaker of.

When the earthquake early warning device 25 of the present embodiment receives an earthquake early warning device event signal from the earthquake early warning device 25, the earthquake early warning device 10 uses information indicating the earthquake early warning as a voice message. Output. An example of a voice message indicating information indicating an Earthquake Early Warning is "Peepy Earthquake Early Warning. Please be wary of strong shaking."

Further, when the Earthquake Early Warning device 25 receives an event signal indicating a fire from the Smoke Detector 10, it outputs an alarm sound indicating a fire. The fire alarm sound of the Earthquake Early Warning device 25 is, for example, a voice message such as "Woo Woo fire alarm has been activated. Please check." Further, the Earthquake Early Warning device 25 may display a fire by lighting, blinking, blinking, or the like of an LED together with a fire alarm sound.

If the event signal contains an identification code (ID) that identifies the Smoke Detector, the Earthquake Early Warning device 25 decodes it, and the content of the voice message indicates which of the Smoke Detector 10 issued the fire alarm. And can be displayed. As mentioned above, the interlocking Smoke Detector system does not have a dedicated receiver, but in this way, the Earthquake Early Warning device 25 can be used as a device that plays the role of a fire receiver in so-called fire alarm equipment. It is possible to collectively manage the fire monitoring network of the Smoke Detector.

Further, the Earthquake Early Warning device 25 is provided with a test switch, and when the test switch is operated, a device event signal indicating an Earthquake Early Warning test is transmitted. Then, the information indicating the Earthquake Early Warning test is notified from the Smoke Detector 10 that has received this by a voice message or the like. A voice message that informs you of information indicating an Earthquake Early Warning test is, for example, "Peepy Earthquake Early Warning test.

When the test switch of the Earthquake Early Warning device 25 is operated, the earthquake warning notification test of the Earthquake Early Warning device 25 itself is performed, and a voice test message such as "Woo Woo fire test" is output.

That is, in the present embodiment, when the test switch of the Earthquake Early Warning device 25 is operated, the device event signal indicating the Earthquake Early Warning test is transmitted to the Smoke Detector 10 to test the notification of the Earthquake Early Warning, and the emergency The earthquake early warning device 25 itself conducts a fire notification test. By doing so, the Earthquake Early Warning device 25 can be linked to the Earthquake Early Warning 10 and the fire alarm notification test of the Earthquake Early Warning device 25 can be performed at the same time.

The implementation of the test using the test switch is not limited to this form, and when the test switch is operated, a device event signal indicating the fire alarm test is transmitted to the Smoke Detector 10 to perform the fire alarm test, and an Earthquake Early Warning is issued. The device 25 itself may perform the fire alarm notification test, or the earthquake early warning device 10 may be sent a device event signal indicating the earthquake early warning test to test the earthquake early warning device. The test notification of the earthquake early warning may be performed. At these times, the Smoke Detector that received the device event signal transmitted from the Earthquake Early Warning device should return the response event signal, and after receiving this, the Earthquake Early Warning device 25 itself should perform the test notification. You can do it. By doing so, the two-way communication test is simultaneously performed between the Earthquake Early Warning device 25 and the Smoke Detector 10, and more reliable operation guarantee can be performed.

Of course, the fire test and the 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 Earthquake Early Warning test may be provided separately.

If the Earthquake Early Warning device 25 is installed in the same place as any of the Smoke Detector 10, the Earthquake Early Warning will be output by voice from both of them, making it difficult to hear. Therefore, in the present embodiment, a prohibition mode for prohibiting the output of the Earthquake Early Warning can be set on the housing guard 10 by a dip switch or the like, and the same place as the Earthquake Early Warning device 25 (a place where the warning and the notification range overlap). By setting the prohibition mode for the residential police equipment installed in), even if an event signal indicating an Earthquake Early Warning is received from the Earthquake Early Warning device 25, the information indicating the Earthquake Early Warning is not output. To do.

The prohibition mode setting function can be used in the same way even when multiple smoke detectors are installed in the same place.

In this way, the prohibition mode setting function may be provided on the side of the Smoke Detector, but in general, it is assumed that the Smoke Detector has more installations than the Earthquake Early Warning device, so it is a system device. It may be provided in the Earthquake Early Warning device 25 in consideration of the overall cost and the like. In this way, it is not necessary to install a prohibition mode setting function on a large number of installed residential guards, the overall cost of system equipment can be suppressed, and an Earthquake Early Warning device can be used to check whether or not a prohibition mode is set. It has the effect of preventing the operation from becoming complicated, such as having to follow only.

In addition, when considering the duplicate notification of the Earthquake Early Warning device and the Smoke Detector and the duplicate notification of the Smoke Detector, both the Smoke Detector and the Earthquake Early Warning device are provided with a prohibition mode setting function and installed. It may be possible to set each according to the situation and the like. At this time, of course, when a plurality of Earthquake Early Warning devices are installed in the same place, it is possible to set so as to avoid duplicate notifications between the Earthquake Early Warning devices.

Of course, even in an installation situation where alarms and notification sounds are output in duplicate, it is not always necessary to use the prohibition mode setting, and it is appropriately selected and set at the user's discretion.

2A and 2B are explanatory views showing the appearance of the wireless smoke detector according to the present invention, FIG. 2A shows a front view, and FIG. 2B shows a side view.

In FIG. 2, the housing of the Smoke Detector 10 of the present embodiment is composed of a cover 12 and a main body 14. A plurality of smoke inlets are opened around the center of the cover 12, and a smoke detection unit 16 is arranged inside the cover 12 so as to detect a fire when the smoke from the fire reaches a predetermined concentration.

A smoke detection unit 16 is provided inside the plurality of openings provided in the cover 12, an acoustic hole 18 is provided on the lower left side of the smoke detection unit 16, and a buzzer and a speaker are built in behind the smoke detection unit 16 to provide an alarm sound and sound. The message can be output. An alarm stop switch 20 is provided below the smoke detection unit 16.

The alarm stop switch 20 also functions as an inspection switch that instructs the self-inspection of the function of the Smoke Detector 10. For example, when the alarm stop switch 20 is operated during a fire alarm, the alarm is stopped, and when the alarm stop switch 20 is operated in the normal state, a function check is performed and the result is notified.

The alarm stop switch 20 is composed of a switch cover formed of a translucent member and a tact switch (not shown) arranged inside the switch cover. An LED 22 that displays an alarm is arranged near the tact switch inside the switch cover as shown by a dotted line. When the LED 22 lights up, blinks, or blinks, the operating light passes through the switch cover portion of the alarm stop switch 20. The operating state of the LED 22 can be seen from the outside.

Further, a mounting hook 15 having an insertion hole in a substantially central portion is provided on the upper part of the back side of the main body 14, and a screw or the like is screwed into the wall of the room to be installed, and the screw is passed through the insertion hole of the mounting hook 15 to be hooked. The Smoke Detector 10 can be fixedly installed on the wall surface in a so-called wall-mounted manner.

The smoke detector 10 in FIG. 1 is provided with a smoke detector 16 and takes as an example a smoke detector that detects smoke caused by a fire. In addition to this, the temperature of a thermista or the like that detects heat caused by a fire is taken. Smoke detectors equipped with detection elements, smoke detectors that detect other physical phenomena associated with fires, alarms that detect gas leaks other than fires, and various alarms that detect intruders, earthquakes, and other abnormalities (abnormalities) A device and an alarm device formed by combining these are also included in the subject of the present invention. The alarm system of the present invention may be configured by mixing these various alarm devices.

FIG. 3 is a block diagram showing an embodiment of the Earthquake Early Warning receiver and the Smoke Detector provided in the warning system of FIG. 1, and the Smoke Detector shows the Smoke Detector 10-1 installed in the living room. , Other Smoke Detectors 10-2 to 10-6 have the same configuration.

The Smoke Detector 10-1 includes a processor 28 known as a one-chip CPU, and for the processor 28, a wireless communication unit 30, a recording circuit unit (memory) 32, a sensor unit 34, and a notification unit 36 equipped with an antenna 31. , The operation unit 38 and the battery power supply 40 are provided.

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 other Smoke Detectors 10-2 to 10-6, and further from the Earthquake Early Warning device 25. It is possible to receive the device event signal of. In the case of Japan, the wireless communication unit 30 is, for example, STD-30 (radio equipment standard for low power security system radio stations) or STD-T67 known as a standard for specific low power radio stations in the 400 MHz band. It has a configuration compliant with (standards for radio equipment for specified low power radio stations telemeters, telecontrols, and data transmissions).

Of course, the wireless communication unit 30 will have the contents conforming to the standard of the assigned radio station in the area for the place other than Japan.

In the memory 32 as a storage unit, a serial number 48 which is a serial number indicating the order of event signals, a source code 50 which is an ID (self-identifier) for identifying each resident police device, and a house as shown in FIG. A group code 52 for forming an interlocking group that gives an interlocking alarm by the installed Smoke Detectors 10-1 to 10-6 is stored.

The serial number 48 is for managing the relay processing of event signals between alarms, especially in wireless communication, but since it is not directly related to the present invention, detailed description thereof will be omitted.

As the source code 50, for example, a 26-bit code code is used so that it does not overlap with any of the Smoke detectors provided in Japan as the same code, and the serial number of the Smoke detector is used.

The group code 52 is a code that is commonly set for a plurality of smoke detectors constituting the interlocking group, and the group code included in the event signal from the other smoke detectors received by the wireless communication unit 30 is registered in the memory 32. Since this event signal is processed as a valid signal when it matches the group code 52, it is unnecessary to use an alarm device installed in a neighboring house or the like and belonging to another group that does not require interlocking. Interlocking can be avoided.

The group code 52 does not necessarily have to be the same code for each smoke detector, and it can be determined whether or not the group to which the self belongs and the group to which the other smoke detectors belong are the same by performing an operation or the like based on the code. Anything is fine.

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

The notification unit 36 is provided with a speaker 56 that outputs an alarm sound or the like and an LED 22 that displays an alarm or 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 amplification unit (not shown). The LED 22 displays an abnormality such as a fire or the like by blinking, blinking, or 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 the alarm sound of fire or failure is output from the notification unit 36 by the speaker 56 or when the alarm is displayed by the LED 22. For example, if the alarm stop switch 20 is operated during the alarm indicating the interlocking source, the alarm sound and the alarm display are stopped, while if the alarm stop switch 20 is operated during the alarm indicating the interlocking destination, the alarm sound is stopped but the alarm is displayed. Alarm stop processing 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 interlocking destination is not performed, the alarm stop switch 20 functions as an inspection switch, and when the alarm stop switch 20 is operated in this state, a predetermined self-inspection operation is executed. A voice message or the like indicating the inspection result is output from the speaker 56 of the notification unit 36.

If the alarm stop switch 20 is operated during the failure alarm, the failure alarm stop process may be performed after performing a predetermined self-inspection operation and notifying the result. By doing so, for example, the failure alarm stop process is performed after rechecking the sensor failure or the like, so that the user can be made to recognize the failure state more clearly. Then, if the failure state is resolved at this time, a message such as "the failure has been resolved" may be output to shift to the 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 surface of the main body or the like, and can set on / off the notification prohibition mode of the Earthquake Early Warning. When the prohibition mode is set (on) by turning on the mode switch 21, even if the device event signal indicating the Earthquake Early Warning is received from the Earthquake Early Warning device 25, the information output indicating the Earthquake Early Warning is output from the notification unit 36. Absent.

Using this function, for example, it is necessary when a smoke detector is installed in the room where the Earthquake Early Warning device is installed, or when multiple smoke detectors are installed in the same room. Since it is possible to output information only to a predetermined device in the room according to the situation, it is possible to avoid duplicate information output by a plurality of devices. In this case, for example, the battery consumption of the prohibited Smoke Detector is suppressed. You can get the effect of being able to do it.

The battery power supply 40 uses, for example, a lithium battery or an alkaline dry battery having a predetermined number of cells, and the battery capacity is, for example, 10 due to the reduction in power consumption of the entire circuit unit including the wireless communication unit 30 in the Smoke Detector 10-1. Guarantees a year of battery life.

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 earthquake early warning processing unit 66 as functions realized by executing a program.

The event detection unit 58 detects an event such as an abnormality (fire in this case) detected by the sensor unit 34, an alarm stop by the operation unit 38, and an abnormality recovery in which the abnormality detection of the sensor unit 34 disappears. Further, the event detection unit 58 transmits the event content obtained as a result of decoding the event signal from the other Smoke detectors 10-2 to 10-6 and the device event signal from the 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 an abnormality detection by the sensor unit 34, an alarm stop by the operation unit 38, an abnormality recovery in which the abnormality detection of the sensor unit 34 disappears, or the like. The event signal is transmitted from the wireless communication unit 30 to the interlocking destination resident police device or the earthquake early warning device. The reception processing unit 62 receives and decodes the event signal from the other Smoke detectors 10-2 to 10-6 and the device event signal from the earthquake early warning device 25 via the wireless communication unit 30.

The type of device event signal is a signal indicating an Earthquake Early Warning or a case where a fire alarm or the like of the Smoke Detector 10 is stopped by operating an operation unit 78 (described later) provided in the Earthquake Early Warning device 25. There is a signal indicating an alarm stop, a signal indicating an Earthquake Early Warning test by operating a test switch 88 (described later) provided in the operation unit 78 of the Earthquake Early Warning device 25, and the like.

Further, when the Smoke Detector 10 receives the device event signal indicating the alarm stop transmitted from the wireless communication unit 80 (described later) of the Earthquake Early Warning device 25 by operating the test switch 88, the Smoke Detector 10 itself may be the interlocking source. The alarm may be continued and stopped if it is an interlocking destination.

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, drives the LED 22 to display an alarm indicating the interlocking source, and further. , The event signal indicating a fire is transmitted to other Smoke Detectors 10-2 to 10-6 and the Earthquake Early Warning Device 25.

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 sets the interlocking source from the speaker 56 of the notification unit 36. An alarm sound indicating, for example, "Woo Woo Fire is a fire" is repeatedly output, the LED 22 is turned on to display an alarm indicating the interlocking source, and an event signal indicating a fire is output via the transmission processing unit 64 and the transmission circuit 42. The transmission circuit 42 of the wireless communication unit 30 transmits from the antenna 31 to other Smoke Detectors 10-2 to 10-6 and the emergency earthquake alarm device 25.

Further, the alarm processing unit 64 receives an event signal indicating a fire from any of the other Smoke detectors 10-2 to 10-6 by the receiving circuit 44 of the wireless communication unit 30, and the reception processing unit 62 becomes effective. Occasionally, the speaker 56 of the notification unit 36 repeatedly outputs an alarm sound indicating the interlocking destination, for example, an alarm sound indicating "Woo, another fire alarm has been activated. Please check", and at the same time, the LED 22 blinks to indicate the interlocking destination. An alarm is displayed to indicate. When the Earthquake Early Warning device 25 receives an event signal indicating a fire from the Smoke Detector 10-1, the Earthquake Early Warning device 25 uses a speaker 74 (described later) to confirm, for example, "Woo Woo fire alarm has been activated." Please output a voice message of "Please".

Here, the event detection unit 58 detects a sensor failure and a low battery failure. To detect a sensor failure, the smoke detection signal output from the smoke detection unit 16 of the sensor unit 34 is read by A / D conversion at a predetermined measurement time interval T1, for example, T1 = 1 second interval, and held in the buffer area of the memory 32. Then, for example, every 10 minutes at a predetermined time interval T2 = 10 minutes, the average value of the detected data for 10 minutes held in the buffer area of the memory 32 is obtained, and this average value is the predetermined reference level (called the zero point level). When the value falls below the level, it is determined that the sensor unit 34 has a failure because the output is stopped.

The reason why the 10-minute average value of the smoke concentration detection signal falls below the zero point level may be due to a failure such as a disconnection of the light receiving element provided in the smoke detection unit 16 or a stop of the light receiving amplifier. Is high. Even when the sensor unit 16 is provided with a temperature detecting element such as a thermistor, the sensor failure can be similarly detected by various processes.

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 hour intervals, comparing it with a predetermined threshold voltage, and when it is below this threshold voltage, it is low. The low battery failure is determined when the battery failure is determined and the low battery failure is continuously determined a predetermined number of times.

When the event detection unit 58 detects a sensor failure or low battery failure, the alarm processing unit 64 outputs a sensor failure or low battery failure alarm indicating the interlocking source by the alarm sound from the speaker 56 of the notification unit 36 and the display of the LED 22. Let me. Further, the alarm processing unit 64 transmits an event signal indicating a sensor failure or a low battery failure to another Smoke Detector 10-2 to 10-6 or an Earthquake Early Warning Device 25, and the Smoke Detector 10-2 to 10-6. Also, the Earthquake Early Warning device 25 is made to issue a sensor failure or low battery failure alarm indicating the interlocking destination with an alarm 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 housing guards 10-2 to 10-6 via the receiving circuit 44 and the receiving processing unit 62. A sensor failure or low battery failure alarm indicating the interlocking destination is output by the alarm sound from the speaker 56 of the unit 36 and the display of the LED 22.

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

Further, the alarm processing unit 64 interlocks by transmitting an event signal indicating a sensor failure to another Smoke Detector 10-2 to 10-6 or an Earthquake Early Warning device 25 via the transmission processing unit 60 and the transmission circuit 42. A sensor failure alarm indicating the above is output. At this time, for example, "another alarm device is out of order" or "an alarm device is out of order" is output as an alarm sound, and a blinking display different from that of the interlocking source is displayed.

If the event signal contains an identification code (ID) that identifies the Smoke Detector, the Earthquake Early Warning device 25 will decode it, and the content of the voice message will indicate which of the Smoke Detector 10 has failed. It can be displayed. This point is the same for the low battery failure described below. The interlocking Smoke Detector system does not have a dedicated receiver, but in this way, the Earthquake Early Warning device 25 can be used as a device that plays the role of a fire receiver in so-called fire alarm equipment. , It becomes possible to manage the monitoring network of the residential alarm system collectively.

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

Further, the alarm processing unit 64 transmits an event signal indicating a low battery failure to another residential alarm 10-2 to 10-6 or an earthquake early warning device 25, thereby issuing a low battery failure alarm indicating the interlocking destination as an alarm sound. As a result, "Pip another alarm is out of battery" or "Pip alarm is out of battery" is output and a blinking display different from the interlocking source is displayed.

Further, when 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 when the other residential alarms 10-2 to 10-6 When either or the reception of the event signal indicating the alarm stop or the device event signal reception is detected from the Earthquake Early Warning device 25, the output of the fire alarm by the voice message from the speaker 56 and the alarm display of the LED 22 is stopped. At this time, the alarm display by the LED 22 may be stopped after continuing for a predetermined time. 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 alarm stop 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 indicating the interlocking source or the low battery failure alarm, the alarm processing unit 64 emits an alarm sound indicating its own interlocking source. An event signal indicating the stop of the alarm to the other housing police 10-2 to 10-6 and the Earthquake Early Warning device 25, which are stopped and the failure display is continued for a predetermined time and then stopped, and the failure alarm is being output to indicate the interlocking destination. Is transmitted to stop the failure warning sound and the failure display of the residential police 10-2 to 10-6 and the Earthquake Early Warning device 25.

When the Earthquake Early Warning processing unit 66 receives a device event signal indicating an Earthquake Early Warning from the Earthquake Early Warning device 25 via the receiving circuit 44 and the receiving processing unit 62, the Earthquake Early Warning processing unit 66 transmits a voice message as information indicating the Earthquake Early Warning. The LED 22 is turned on, blinking or blinking while being output from the speaker 56 of the notification unit 36.

Further, when the Earthquake Early Warning processing unit 66 receives the device event signal indicating the Earthquake Early Warning test from the Earthquake Early Warning device 25, the Earthquake Early Warning processing unit 66 outputs a voice message indicating the Earthquake Early Warning test from the speaker 56 of the notification unit 36. Turn on, blink or blink LED 22.

Further, when the Earthquake Early Warning processing unit 66 has set a prohibition mode for prohibiting the output of information indicating the Earthquake Early Warning by turning on the setting of the mode switch 21, the Earthquake Early Warning device 25 issues an Earthquake Early Warning. Even if the indicated device event signal is received, the voice message of the information indicating the Earthquake Early Warning test is not output.

Prohibition of voice message output by the mode switch 21 may also be set for Earthquake Early Warning.

Further, when the prohibition mode setting switch is provided in the operation unit 78 of the earthquake early warning device 25 described later, the fire alarm output from the earthquake early warning device 25 may be prohibited by setting the prohibition mode switch.

Further, even when the voice message or the acoustic 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 Earthquake Early Warning and the Earthquake Early Warning test, and the acoustic output and the display output.

In this way, the notification method can be selectively set according to the type of event for which notification output is performed, and an appropriate notification pattern can be set according to the user's wishes 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 is composed of a processor 68, an FM receiver 70 having an antenna 71, a voice amplification unit 72, a speaker 74, a display unit 76, an operation unit 78, and a wireless communication unit 80. The Earthquake Early Warning analysis unit 90, the device event detection unit 92, the transmission control unit 94, the reception control unit 96, and the alarm control unit 98 are provided as functions to be realized by execution.

The FM receiving unit 70 synchronizes the tuner with the FM station selected by the operation of the operating unit 78, receives the FM broadcast radio wave via the FM antenna 71, demodulates it as an audio signal, and outputs it. The audio amplification unit 72 is stopped in the standby state, and therefore, the reproduction output of the FM broadcast received from the speaker 74 is not performed. When the Earthquake Early Warning signal is detected by the analysis processing of the processor 68, the voice amplification unit 72 is switched to the operating state, and at that time, the broadcast content of the Earthquake Early Warning reproduced and output from the FM receiving unit 70 is transmitted via the amplification unit 72. Is output from the speaker 74. The display unit 76 displays a reception standby display, an earthquake early warning reception display, a channel selection frequency display, and other displays necessary for receiving FM broadcasts, as well as a fire warning 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 Smoke Detector 10. Similar to Smoke Detector 10-1, the wireless communication unit 80 conforms to STD-30 or STD-T67, which is known as a standard for specific low power radio stations in the 400 MHz band, for example, in Japan. It has a configuration.

In the memory (not shown), like the memory 32 of the Smoke Detector 10-1, a serial number indicating the order of the event signals and an ID (self-identifier) for identifying the Earthquake Early Warning device are transmitted. The original code and the group code for forming the 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 result of the two chime sounds that first flow in the Earthquake Early Warning by the Earthquake Early Warning analysis unit 90. The alarm control unit 98 operates the voice amplification unit 72 for a predetermined time to reproduce and output the Earthquake Early Warning from the speaker 74. The earthquake early warning chime sound is analyzed by the Earthquake Early Warning analysis unit 90 by, for example, the vector correlation method described in Patent Document 3.

The device event detection unit 92 detects device events such as the earthquake early warning signal reception by the earthquake early warning analysis unit 90 and the event signal reception from the Smoke Detector 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 Earthquake Early Warning to the Smoke Detector 10 side, and outputs information indicating the Earthquake Early Warning. .. The reception control unit 96 receives the event signal from the Smoke Detector 10 via the reception circuit 86.

When the device event detection unit 92 detects the reception of an event signal indicating a fire from any of the housing guards 10, the alarm processing unit 98 operates the voice amplification unit 72 to output an alarm sound from the speaker 74. At the same time, the display unit 76 is made to display a fire. Further, the alarm processing unit 98 stops the alarm sound and the fire display when the device event detection unit 92 receives an event signal indicating fire recovery or alarm stop from any of the residential guards 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, and based on this, the transmission control unit 94 transmits a device event signal indicating an Earthquake Early Warning test to the Smoke Detector 10 side for the test. Notify operation.

Further, the alarm control unit 98 may cause the speaker 74 and the display unit 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 unit 92.

Further, when a mode switch for setting the prohibition of fire alarm is provided in the operation unit 78 and the earthquake early warning device 25 is installed in the same place as the alarm, or when the interlocking notification of the fire alarm is not required, the mode switch is used. The fire alarm may be prohibited by the operation.

The power source of the Earthquake Early Warning device 25 may be a commercial AC power source or a battery. Further, it may be another dedicated power supply.

FIG. 4 is an explanatory diagram showing the formats of the event signal and the device event signal used for the interlocking alarm in the present embodiment. In FIG. 4, the event signal 46 is composed of a serial number 48, a 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 signals, and is incremented by 1 each time the event signal is transmitted. Further, the serial number 48 is generated asynchronously by each of the Smoke Detector 10 and the Earthquake Early Warning Device 25. The serial number 48 is for managing the relay processing of the event signal mainly in wireless communication between the Smoke Detector 10 and the Earthquake Early Warning Device 25, but since it is not directly related to the present invention, a detailed description thereof will be given. Is omitted.

The source code 50 is, for example, a 26-bit code, and uses the serial number of the Smoke Detector 10 and the Earthquake Early Warning device 25. The group code 52 is, for example, an 8-bit code, and the same group code is set for, for example, the Smoke Detector 10-1 to 10-6 and the Earthquake Early Warning device 25 of FIG. 1 that form the same group.

As the group code 52, in addition to setting the same group code for the smoke detectors of the same group, for example, a reference code common to the smoke detectors constituting a predetermined group and a transmission unique to each smoke detector. The group code may be different for each Smoke detector obtained from the calculation with the original code.

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

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

5 and 6 are flowcharts showing an example of the monitoring process in the Smoke Detector 10-1 of FIG. The same process applies to other Smoke detectors 10-2 to 10-6. In FIG. 5, when the power supply by the battery power supply 40 of the Smoke Detector 10-1 is started, initialization, self-diagnosis, and reading of various settings including the presence / absence of the prohibition mode setting are executed in step S1, and an abnormality is found. If not, the process proceeds to step S2 to monitor the fire. When the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, the fire is determined in step S2 and the process proceeds to step S3, and an event signal including a serial number, a source code, a group code, and an event code indicating a fire is included. Is wirelessly transmitted to other residential alarms and the emergency earthquake alarm device 25, and then in step S4, the interlocking source is indicated by an alarm sound such as a voice message or a buzzer sound from the speaker 56 of the notification unit 36 and an alarm display by lighting the LED 22. Output 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 lowered and the fire state is resolved. When the fire recovery is determined, the serial number, the source code, and the group code are determined in step S6. After transmitting an event signal including an event code indicating fire recovery to other residential alarms and the emergency earthquake alarm device 25, the interlocking source is indicated by the alarm sound from the speaker 56 and the alarm display by lighting the LED 22 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, in step S8, the presence / absence of operation of the alarm stop switch 20 is determined, and when the switch operation is determined, the presence / absence of an alarm is determined in step S9. When it is determined in step S9 that an alarm is in progress, the process proceeds to step S10 to transmit an event signal including a serial number, a source code, a group code, and an event code indicating an alarm stop to other residential police equipment and the Earthquake Early Warning device 25. Then, the process proceeds to step S11 to stop the alarm sound output from the speaker 56 indicating the interlocking source, and turn off the alarm display due to the lighting of the LED 22. The LED 22 may be turned off after a lapse of a predetermined time.

When it is determined in step S9 that the alarm is not in progress, a predetermined inspection operation is performed to notify the result, but the illustration is omitted.

Subsequently, the process proceeds to step S12 of FIG. 6, and it is determined whether or not an event signal indicating a fire is received from another Smoke Detector. When it is determined that an event signal indicating a fire is received from another residential alarm, the process proceeds to step S13 to output an alarm sound from the speaker 56 as a fire alarm indicating the interlocking destination, and display an alarm by blinking the LED 22.

Next, in step S14, it is determined whether or not an event signal indicating fire recovery is received from another resident police device, and when an event signal indicating fire recovery is received, the process proceeds to step S15 to alert the interlocking destination. The alarm sound output from the speaker 56 and the alarm display by blinking the LED 22 are stopped.

Next, in step S16, it is checked whether or not an event signal indicating an alarm stop from another residential police device or an event signal indicating an alarm stop from the Earthquake Early Warning device 25 is received, and an event signal or an apparatus indicating an alarm stop is checked. When it is determined that the event signal has been received, the process proceeds to step S17 to determine whether or not an alarm is in progress, and when it is determined that an alarm is in progress, the process proceeds to step S18 to stop the alarm sound output as the interlocking destination and also stop the alarm display.

Subsequently, in step S19, it is determined whether or not the Earthquake Early Warning prohibition mode is set, and if the prohibition mode is not set, the process proceeds to step S20 to check whether or not an event signal indicating the Earthquake Early Warning is received. When it is determined that the device event signal indicating the Earthquake Early Warning from 25 is received, the 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.

When the prohibition mode setting of the Earthquake Early Warning is determined in step S19, steps S20 and S21 are skipped, and the emergency earthquake notification message is not output even if the reception of the device event signal indicating the Earthquake Early Warning is determined. This is the case where the Smoke Detector 10-1 is installed in the same room as the Earthquake Early Warning device 25 as shown in FIG. The order of steps S19 and S20 may be changed.

Subsequently, the process proceeds to step S22 to check whether or not an event signal indicating an Earthquake Early Warning test has been received, and when it is determined that an event signal indicating an Earthquake Early Warning test has been received, an Earthquake Early Warning test message is notified in step S23. The output 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 process is repeated until an operation stop instruction due to power off is determined.

In the flowcharts of FIGS. 5 and 6, the notification stop processing of the Earthquake Early Warning or the Earthquake Early Warning test by operating the test switch 88 provided in the operation unit 78 of the Earthquake Early Warning device 25 is omitted, but the Earthquake Early Warning During the notification of the early warning or the Earthquake Early Warning test, it may be determined whether or not the device event signal indicating the notification stop is received, and the notification may be stopped when the notification is received.

In addition, it is determined whether or not the alarm stop switch 20 is operated during the notification of the Earthquake Early Warning or the Earthquake Early Warning test, and if there is an operation, the alarm is stopped (or the notification is stopped) to other residential police or the Earthquake Early Warning device. It is possible to send an event signal indicating that the notification by another alarm device or an Earthquake Early Warning device is stopped.

FIG. 7 is a flowchart showing a processing example of the Earthquake Early Warning device 25 shown in FIG. In FIG. 7, when the power of the 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 and the FM station is selected by the channel selection operation of the operation unit 78. ..

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

Subsequently, in step S34, the presence or absence of reception of the earthquake early warning chime sound is determined through the analysis process of the Earthquake Early Warning analysis unit 90. When the chime sound reception is determined, the process proceeds to step S35 and the voice amplification unit 72 is operated. The Earthquake Early Warning broadcast received at that time is output from the speaker 74 at a sufficiently loud volume.

Next, in step S36, the transmission circuit 84 of the wireless communication unit 80 is operated, and a device event signal indicating an Earthquake Early Warning is output to the Smoke Detector 10. Subsequently, in step 37, after waiting for the elapse of a predetermined time, the process proceeds to step S38, and the operation of the audio amplification unit 72 is stopped to stop the output of the broadcast sound.

If the operation unit 78 detects a notification stop instruction during the earthquake early warning broadcast sound output from the speaker 74, the earthquake early warning broadcast sound output is interrupted (not shown).

Subsequently, the process proceeds to step S39, and it is determined whether or not an event signal indicating a fire is received from any of the Smoke Detector 10. When it is determined in step S39 that an event signal indicating a fire is received from any of the residential alarms 10, the process proceeds to step S40, and the speaker 74 and the display unit 76 output a fire alarm by an alarm sound and an alarm display.

Next, in step S41, it is checked whether or not an alarm stop instruction is given by the operation of the operation unit 78 and whether or not an event signal indicating fire recovery or an alarm stop is received from any of the Smoke Detector 10. When it is determined that an operation instruction or an event signal indicating fire recovery or an event signal reception indicating an alarm stop is determined, the process proceeds to step S42 to determine whether or not an alarm is in progress, and when it is determined that an alarm is in progress, the process proceeds to step S43 for an alarm sound and an alarm. Stop the display. When the alarm is stopped based on the operation instruction of the operation unit 78, the device event signal indicating the alarm stop is output from the transmission circuit of the wireless communication unit 80 to the housing guard 10 (not shown). The above process is repeated in step S44 until an operation stop instruction due to power off is determined.

In the above embodiment, a residential alarm that detects a fire and gives an alarm is taken as an example, but an alarm system in which a gas leak alarm, a CO alarm, and various security alarms are arranged and various of them are used. The same can be applied to an alarm system in which the alarm devices of the above are mixed and arranged.

Further, the interlocking output of the abnormality alarm (fire alarm, etc.) from the residential police device to the earthquake early warning device may be performed only by the display. For example, if you want to improve the visual notification effect of an abnormality by using a flashlight that consumes a lot of power, a commercial power supply is sufficient for the sound alarm output such as buzzer sound and voice message. A display device such as the flashlight is installed in the emergency earthquake bulletin device, which has a relatively low need to reduce power consumption by using a dedicated power supply, etc., and is linked to an abnormality (fire) alarm of the residential police.
