Description

The present invention relates to an alarm device and an alarm system that detect and alarm an abnormality such as a fire or a gas leak and relay and transmit a signal to another alarm device to output an alarm in conjunction.

  Conventionally, residential alarms (hereinafter referred to as “residential alarms”) that detect and warn of fires in houses have become widespread. In recent years, a plurality of residential alarms can communicate with each other to provide a single residence. Wireless dwelling alarms for linked alarm systems that can alarm alarm information with other alarms have been put into practical use, and some of these operate by battery power.

  In a linked alarm system that performs wireless communication, if a fire is detected by a certain home alarm, the home alarm that detected the fire is, for example, “Woo Woo Fire Alarm has been activated. Please send a voice message saying "Please," while the linked house alarm outputs a voice message saying "Check if a fire alarm for each Woo has been activated". In addition, the indicator light of the interlocking home alarm device is turned on, and the indicator light of the interlocking destination home alarm device is blinking so that the interlock source or the interlocking destination can be distinguished from the display of the indicator light.

  In addition, when an alarm is issued by the interlocking source and the interlocking home dwelling unit, the alarm of the operated dwelling unit can be stopped by operating the alarm stop switch provided in the dwelling unit. .

  FIG. 1 is an explanatory view showing the appearance of a wireless house alarm according to the present invention. FIG. 1 (A) shows a front view and FIG. 1 (B) shows a side view.

  In FIG. 1, the residential alarm 10 according to the present embodiment includes a cover 12 and a main body 14. A smoke inlet is opened in the center of the cover 12, and a smoke detector 16 is disposed inside the cover 12 so that a fire is detected when smoke from the fire reaches a predetermined concentration.

  An acoustic hole 18 is provided on the lower left side of the smoke detector 16 provided in the cover 12, and a buzzer and a speaker are built in behind this so that an alarm sound and a voice message can be output. An alarm stop switch 20 is provided below the smoke detector 16. The alarm stop switch 20 also has a function as an inspection switch for instructing a functional inspection of the home alarm. 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 a normal state, a function check is started and the result is notified.

  The alarm stop switch 20 includes a switch cover formed of a translucent member and a tact switch (not shown) arranged inside the switch cover. In the vicinity of the tact switch inside the switch cover, an LED 22 for displaying is arranged as indicated by a dotted line. When the LED 22 is lit, the LED 22 is lit from the outside through the switch cover portion of the alarm stop switch 20. I understand it.

A mounting hook 15 is provided on the upper rear side of the main body 14, and a screw or the like is screwed into the wall of the installation room, and the mounting hook 15 is passed through the screw , so that the residential alarm 10 can be installed on the wall surface. it can.

  In addition, in the residential alarm 10 of FIG. 1, although the residential alarm which detects the smoke by the fire provided with the smoke detection part 16 is taken as an example, temperature of the thermistor etc. which detects the heat by a fire besides this is also taken. House alarms with detection elements, house alarms that detect other physical phenomena associated with fires, alarms that detect gas leaks in addition to fires, various alarms that detect intruders, earthquakes, and other abnormalities, etc. Alarm devices formed by combining these are also included in the subject of the present invention.

  FIG. 2 is an explanatory diagram showing an installation state of the alarm system of the present embodiment for a house. In the example of FIG. 2, there are residence alarm devices 10-1 to 10-4 for detecting and alarming the fire of this embodiment in each of the kitchen, living room, main bedroom, and child room provided in the house 24. The resident guard 10-5 is also installed in the garage 26 which is installed and is built outdoors.

  The home alarm devices 10-1 to 10-5 have a function of transmitting / receiving event signals to / from each other wirelessly, and perform fire monitoring of the entire house.

  If a fire has occurred in the child's room of the house 24, the residence guard 10-4 detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm. When the resident alarm 10-4 is triggered, the resident guard 10-4 functions as an interlocking source, and fires are issued to the other resident alarms 10-1 to 10-3 and 10-5 that are the interlocking destinations. An event signal indicating is transmitted by radio. When the other home alarm devices 10-1 to 10-3 and 10-5 receive the event signal indicating the fire alarm from the home alarm device 10-4 as the interlocking source, the alarm sound and display indicate the interlocking destination. The alarm action is performed.

  Here, as the alarm sound of the home alarm device 10-4 that has become the link source, for example, “Please confirm that the Woo fire alarm has been activated” is output by a voice message. On the other hand, in the interlocked residence alarm devices 10-1 to 10-3, 10-5, a voice message such as “Please confirm that another fire alarm has been activated” is output.

  Moreover, as a display of the home guard 10-4 which became the interlocking | linkage origin, LED22 is lighted, for example (1st display). On the other hand, in the interlocked residence police 10-1 to 10-3 and 10-5, the LED 22 is blinked (second display). Thereby, the display by the LED 50 in the interlocking source alarm and the interlocking destination alarm can be distinguished.

  The interlocking source LED 22 may be blinking (first display), and the interlocking destination LED 22 may be lit (second display). For both the interlocking source alarm and the interlocking destination alarm, It may be blinking or lighting display.

  When any of the alarm stop switches is operated in a state in which the house alarm devices 10-1 to 10-5 are outputting an alarm sound, an alarm sound or display stop processing is performed.

  FIG. 3 shows the alarm stop in the present embodiment. In this embodiment, when the alarm stop switch of the interlocking source is operated during the interlocking alarm, the alarm sound of the interlocking source, the alarm sound of the interlocking destination, and the display of the interlocking destination are stopped, and some indication about the interlocking source is made. At least for a predetermined period. On the other hand, when the alarm stop switch of any linkage destination is operated during the linkage alarm, all the linkage destination alarm sounds are stopped, the linkage source alarm sounds are maintained, and some indication is displayed for the linkage destination for at least a predetermined period. I do.

  FIG. 3 (A) shows that the house guard 10-1 among the house guards 10-1 to 10-5 that are linked to each other detects a fire, and the house guard 10-1 turns on the alarm sound and the LED 22, for example ( A fire alarm indicating the interlocking source is performed by the display of the first display), and the remaining dwelling devices 10-2 to 10-5 perform a fire alarm indicating the interlocking destination by a display that blinks the alarm sound and the LED 22, for example. .

  When the alarm stop switch 20 provided in the interlocking home resident alarm 10-1 is operated in the state of the interlocking alarm, as shown in FIG. However, the display by turning on the LED 22 (first display) continues for a predetermined period. Moreover, the alarm sound and display which are performed in the interlocking destination house alarm devices 10-2 to 10-5 are stopped.

  In this way, the interlocking source continues to be lit (may be lit again after a short period of stoppage). In this case, for example, the drive current is reduced compared to the display before the alarm is stopped, and the dim lighting (third Or a blinking state (second display), and the blinking display at this time may be the same as the blinking display during alarming (second display) at the interlock destination. .

  In addition, even after the alarm stops as an interlocking source, even if it shifts to flashing with a longer cycle (flashing under a driving condition with a small duty ratio: third display), power consumption after the alarm stop operation is suppressed. I can do it. And the alarm sound which shows the interlocking destination currently performed with interlocking | destination residence alarm device 10-2 to 10-5, and the display by blinking of LED22 are all stopped.

  On the other hand, when the alarm stop switch 20 provided in any of the interlocked residence police devices 10-2 to 10-5 is operated, as shown in FIG. 4, the interlocked residence police device 10- Although all the alarm sounds 2 to 10-5 are stopped, the alarm sound output and some kind of display are continuously performed for a predetermined period for the interlocking home alarm device 10-1.

  In this case, the display of the interlocking destination home alarm devices 10-2 to 10-5 continues to flash (second display) without stopping (may be flashed again after stopping for a short time) or alarm. The driving method (fourth display) is different from that before stopping.

  In addition, in any residence alarm device, the alarm sound of the interlocking source may be slightly output during the period until the interlocking source display (history display) is stopped. In other words, after the alarm is stopped, the interlocking home alarm can perform intermittent sound output at a lower volume and / or longer period than during the alarm while displaying the history.

Here, the first to fourth display examples are arranged as follows.
First display: Illuminated Second display: Flashing Third display: Dark lighting / Blinking with a small duty ratio Fourth display: Different from the third display, blinking with a small duty ratio In this way, the first display, According to the combination of the second display, the third display, and the fourth display, it is possible to know the history of operation as the interlocking source or the interlocking destination even after the alarm is stopped.

  In this way, when the interlocking source alarm stop switch is operated during the interlocking alarm, the alarm sound of the interlocking source, the alarm sound of the interlocking destination, and the display of the interlocking destination are stopped, and some display for the interlocking source is displayed for at least a predetermined period. Do. On the other hand, when the alarm stop switch of any interlocking destination is operated during the interlocking alarm, the alarm sound of all interlocking destinations is stopped, at least the alarm sound of the interlocking source is maintained, and at least for a predetermined period of time for the interlocking destination Display.

  As a result, it can be seen that the other alarm device (link source) is still in alarm at the link destination, so the link destination alarm device where the alarm stop operation was performed is a place where the alarm sound from the link source cannot be heard. However, since the alarm sound at the interlocking destination is stopped by the alarm stop operation at the interlocking destination, safety can be ensured without being misidentified as a non-fire report or a false alarm.

  In addition, even after the alarm stop operation is completed, the history display is different between the linkage source and the linkage destination at least for a predetermined period (the history of the linkage source may not be displayed), so it is possible to identify the fire source after fire extinguishment, Alternatively, it is possible to easily and reliably identify a home alarm device that has issued a non-fire report. When an alarm stop operation is performed at the interlocking destination, the alarm sound at the other interlocking destination stops, but the alarm sound at the interlocking source is not stopped, so the interlocking source can be found by relying on the sound. Therefore, in this case, the display of the interlocking source may be stopped.

Alarm display by LED22 of the interlocking source home alarm 10-1 continues after stopping, when predetermined time determined by the timer setting or stop when performing the alarm stop operation again.

  FIG. 5 (A) shows the alarm processing in this embodiment separately before the alarm stop, after the interlocking source alarm stop operation, and after the interlocking destination alarm stop operation. FIG. 5B shows the display processing in this embodiment separately before alarm stop, after interlocking source alarm stop operation, and after interlocking destination alarm stop operation.

  FIG. 6 is a block diagram showing an embodiment of a residential alarm provided in the alarm system of FIG. FIG. 6 shows in detail the circuit configuration of the five home guards 10-1 to 10-5 shown in FIG. It becomes the same structure also about the other residence guards 10-2 to 10-5.

  Although the arrow which connects the residence guard 10-1 and the other residence guards 10-2 to 10-5 has shown that each communicates, for example, the residence guard 10-2 and the residence guard 10-3 And so on. Of course, the present invention can also be applied to a system in which the home alarm device 10-1 is used as a base unit of the system and communication is performed only along the route indicated by the arrow in FIG.

  The home guard 10-1 includes a processor 28 known as a one-chip CPU. For the processor 28, a wireless communication unit 30 including an antenna 31, a recording circuit unit (memory) 32, a sensor unit 34, and a notification unit 36. An operation unit 38 and a battery power source 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 transmitted and received wirelessly between the other residential alarm devices 10-2 to 10-5. As the wireless communication unit 30, in Japan, for example, STD-30 (wireless equipment standard of a low power security system wireless station) or STD-T67 known as a standard of a specific low power wireless station of 400 MHz band. It has a configuration that conforms to the standard for specific low-power radio station telemeters, telecontrol and data transmission radio equipment.

  Of course, the wireless communication unit 30 has contents conforming to the standard of the assigned wireless station in the area in places other than Japan.

The memory 22 as a storage unit, the serial number 48 is a sequential number indicating the order of events signals were installed in houses as transmission source code 50 and 2 the ID for identifying the home alarm (identifier) The group code | symbol 52 for comprising the interlocking | linkage group which performs an interlocking | linkage alarm with the house alarm devices 10-1 to 10-5 is stored.

  The serial number 58 is used for managing the relay processing of the event signal in the communication between the alarm devices, but will not be described in detail because it is not directly related to the present embodiment.

  As the transmission source code 50, the number of home guards provided in the country is predicted, and for example, a 26-bit code code is used so as not to be duplicated as the same code.

  The group code 52 is a code that is set in common to a plurality of house alarms constituting the interlocking group, and the group code included in the event signal from another house alarm received by the wireless communication unit 30 is registered in the memory 32. When this event signal matches the group code 52, the event signal is received and processed as a valid signal. Interference can be avoided.

  In addition to the smoke detector 16, the sensor unit 34 may be provided with a temperature detection element such as a thermistor for detecting the temperature due to a fire, and various elements for detecting other physical phenomenon changes associated with the fire.

  The notification unit 36 is provided with a speaker 58 that outputs an alarm sound and an LED 22 that performs display. The speaker 58 outputs a voice message or an alarm sound from a voice synthesis circuit unit (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting. Instead of the speaker 48, a buzzer or the like may be used.

  The operation unit 38 is provided with an alarm stop switch 20. The alarm stop switch 20 is effective only when an alarm sound is displayed from the notification unit 36 by the speaker 48 or by the LED 22. On the other hand, the alarm stop switch 20 functions as an inspection switch in a normal monitoring state in which an alarm indicating the interlocking source or the interlocking destination is not performed. When the inspection switch is pressed in this state, a predetermined inspection operation is performed and the notification unit 36 A voice message indicating the inspection result is output.

  The battery power source 40 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and has a battery capacity of, for example, 10 by reducing the power consumption of the entire circuit unit including the wireless communication unit 30 in the residential alarm 10-1. The battery life of the year is guaranteed.

  The processor 28 is provided with an event detection unit 60, a transmission processing unit 62, a reception processing unit 64, an alarm processing unit 66, and an alarm stop unit 68 as functions realized by executing the program.

The reception processing unit 64 determines validity / invalidity and decodes the event signal from the house alarm devices 10-2 to 10-5 received by the reception circuit 44.

The alarm processing unit 66 outputs an alarm sound indicating the interlocking source from the speaker 58 when the event detection unit 60 detects a fire as its own abnormality, and drives the LED 22 to display the interlocking source. Sends an event signal indicating a fire to other home alarms.

More specifically, the alarm processing unit 66 generates an alarm sound indicating the interlock source from the speaker 58 of the notification unit 36 when the event detection unit 60 detects a fire from the smoke detection signal from the sensor unit 34, for example, “Woooo fire”. "Alarm was activated, please check" Please repeatedly output "LED22 is turned on to display the interlock source, and an event signal indicating a fire is transmitted from the antenna 31 by the transmission circuit 42 of the wireless communication unit 30. It is made to transmit toward other dwelling devices 10-2 to 10-5.

  Further, the alarm processing unit 62 receives an event signal indicating a fire from any of the other residential alarm devices 10-2 to 10-5 by the reception circuit 44 of the wireless communication unit 30, and becomes effective in the reception processing unit 64. Sometimes, an alarm sound indicating the link destination is repeatedly output from the speaker 58 of the notification unit 36, for example, “Woooo Please check if another fire alarm has been activated”, and the LED 22 blinks simultaneously. Is displayed.

  The alarm stop unit 68 performs the following processes (1) to (5).

  (1) When the alarm stop operation of the alarm stop switch 20 provided in the operation unit 38 is detected during the output of the fire alarm indicating the interlock source, an alarm sound from the speaker 58 indicating the interlock source, for example, “Woo Woo fire alarm Confirm that it has been activated "and continue the display by turning on the LED 22, and further stop the alarm for the other residential alarm devices 10-2 to 10-5 via the transmission processing unit 62 and the transmission circuit 42. An event signal is transmitted.

  (2) If an event signal reception indicating an alarm stop is detected from another dwelling device 10-2 to 10-5 while an abnormal alarm indicating the interlock source is being output, the alarm sound indicating the interlock source is continued and turned on. The LED 22 that has been turned off is turned off. Thereafter, when the alarm stop switch of the interlocking source (self) is operated, the alarm sound indicating the interlocking source is stopped and the LED 22 is turned on. It may be lit dark, flashing, or flickering. And the event signal which shows a warning stop is transmitted to other dwelling devices 10-2 to 10-5 via the transmission process part 62 and the transmission circuit 42. FIG.

(3) When an alarm stop operation of the alarm stop switch 20 provided in the operation unit 38 is detected during output of an abnormality alarm indicating the interlock destination, the alarm sound from the speaker 58 indicating the interlock destination is stopped and blinking.

If there is no means for discriminating whether the signal is from the linkage source or the linkage destination, the alarm sound from the speaker 58 indicating the linkage destination is stopped and the display of the blinking LED 22 is stopped. To.

(7) when they are continuously displayed after an alarm stop operation as a linkage destination, when the self-alarm stop switch 20 is operated, and continues the display of the LED22 with (may be stopped), the transmission processing unit 62 Then, an alarm stop signal is transmitted to another alarm device via the transmission circuit 42. Note that if there is no means for determining whether the signal is from the interlocking source or the interlocking destination, the event signal indicating the alarm stop is not transmitted to the other alarm devices.

(8) when they are continuously displayed after an alarm stop operation as the linkage source, if the self-alarm stop switch 20 is operated, it stops the display of the LED 22. And the event signal which shows an alarm stop is transmitted with respect to another alarm device via the transmission process part 62 and the transmission circuit 42. FIG.

  FIG. 7 is an explanatory diagram showing the format of the event signal used in this embodiment. In FIG. 7, 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 event signals, and is incremented by one each time an event signal is transmitted. In addition, the serial number 48 is generated asynchronously in each of the residential alarm devices 10-1 to 10-5. The serial number 48 is for managing the relay processing of the event signal in the communication between the alarm devices, but will not be described in detail because it is not directly related to the present embodiment.

  The transmission source code 50 is a 26-bit code, for example. The group code 52 is, for example, an 8-bit code, and the same group code is set for, for example, the residential alarm devices 10-1 to 10-5 in FIG.

  In addition, as the group code 52, in addition to setting the same group code to the same group of house alarms, a reference code common to the house alarms constituting a predetermined group, and a transmission source unique to each house alarm A different group code may be used for each residential alarm obtained from the calculation with the code.

  The event code 54 is a code representing the event content such as fire and gas leak. In the present embodiment, a 3-bit code is used. For example, “001” indicates a fire, “010” indicates a gas leak, “ “011” indicates theft, “100” stops the alarm, “101” recovers, and the rest is reserved. Note that the number of bits of the event code 42 can be increased to 4 bits and 5 bits when the type of event is increased, thereby expressing more event contents.

Moreover, in this embodiment, when the event signal indicating the alarm stop is received by the interlocking destination home alarm device, it is necessary to determine whether the transmission source is the interlocking source or the interlocking destination, which indicates a fire. When the event signal is received, the transmission source code 50 is stored in the memory 32. After that, when the event signal indicating the alarm stop is received, the received transmission source code and the transmission source code stored in the memory 32 are stored. If they match, the transmission source can be determined as the interlocking source, and if they do not match, the transmission source can be determined as the interlocking destination. In addition to this, it is also possible to provide a code for identifying whether the event signal is a signal from the link source or the signal from the link destination in the event signal, and this code determination is performed when the event signal is received. Hereinafter, the former method will be described as an example.

  FIG. 8 is a flowchart showing an example of a fire monitoring process in the residential alarm device 10-1 in FIG. 4, which is a process by executing a program of the processor 28.

  In FIG. 8, the fire monitoring process monitors the occurrence of fire in step S1, and if the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, the fire is determined and the process proceeds to step S2. After transmitting an event signal including a transmission source code, a group code, and an event code indicating a fire to another house alarm device by radio, an alarm sound from the speaker 58 and display by lighting of the LED 22 are indicated in step S3. Outputs a fire alarm.

  Subsequently, in step S4, it is determined whether or not there is a fire restoration in which the smoke detection signal from the sensor unit 34 is reduced and the fire disappears. If the fire continues, an alarm stop operation by the alarm stop switch 20 is performed in step S5. If there is no alarm stop operation, the process of determining whether or not an alarm stop event signal has been received from another residential alarm is repeated in step S6. In addition, while the fire is continuing, the transmission of the event signal indicating the fire alert is repeated every predetermined time.

  During the processing cycle of steps S4 to S6, when the smoke detection signal from the sensor unit 34 decreases and the fire disappears, fire recovery is determined in step S4. In step S8, the serial number, transmission source code, group code, and fire recovery are determined. An event signal including the event code shown is transmitted to the other residential alarm, and the process proceeds to step S12 to stop the alarm sound and display indicating the interlocking source. In this case, the normal monitoring state is restored. When fire recovery is determined in step S4, the process may proceed to S11, determine that a predetermined time has elapsed, and then proceed to S12.

  If it is determined in step S5 that the alarm stop switch 20 has performed its own alarm stop operation, the process proceeds to step S9, and an event signal including a serial number, a transmission source code, a group code, and an event code indicating alarm stop is transmitted to the other mortgage. In step S10, the alarm sound from the speaker 58 indicating the interlocking source is stopped and the display by turning on the LED 22 is continued as it is. Instead of continuing lighting as it is, it may be switched to dark lighting, blinking, or blinking.

  If it is determined in step S6 that an alarm stop event signal has been received from another residential alarm device, the process proceeds to step S7 where the alarm sound from the speaker 58 indicating the interlock source is continued and the display by lighting the LED 22 is continued. Instead of continuing lighting as it is, it may be switched to dark lighting, blinking, or blinking, or in this case, it may be stopped.

After the alarm sound is continued and the display is stopped in step S7, or after the alarm sound is stopped and the display is continued in step S10, in this embodiment, the elapse of a predetermined time is determined in step S11. Sometimes the process proceeds to step S12 to stop the alarm sound and display indicating the interlocking source.

In addition, when the alarm stop operation by the alarm stop switch 20 is detected again while determining whether the predetermined time has elapsed since the event signal indicating the alarm stop operation or the alarm stop in step S11, an alarm sound indicating the interlock source The display may be stopped. Further, although the alarm sound indicating the interlock source is stopped, the display may be continued and stopped when it is determined that a predetermined time has elapsed.

  On the other hand, if it is not a fire in step S1, it is determined in step S13 whether or not an event signal has been received from another residential alarm. When it is determined that an event signal indicating a fire from another house alarm is determined, the process proceeds to step S14, where a warning sound from the speaker 58 and a blinking LED 22 are displayed as a fire alarm indicating the interlocking destination.

  Next, in step S15, it is determined whether or not an event signal indicating a fire recovery from another residential alarm is received, and when an event signal indicating a fire recovery is received, the process proceeds to step S16 and is performed as an interlocking destination alarm. The display by the alarm sound from the speaker 58 and the blinking of the LED 22 is stopped.

  If no event signal indicating a fire recovery is received in step S15, it is checked in step S17 whether an event signal indicating an alarm stop from another house alarm is received, and an event signal indicating an alarm stop is received. Is determined, the process proceeds to step S18 to determine whether or not the transmission source is the interlocking source. If it is determined in step S18 that the transmission source is the interlocking source, the process proceeds to step S19, and the display by the alarm sound from the speaker 58 indicating the interlocking destination and the blinking of the LED 22 is stopped. On the other hand, if it is determined in step S18 that the transmission source is the interlocking destination, the process proceeds to step S22. In this case, the alarm sound from the speaker 58 indicating the interlocking destination is stopped, and the display by blinking of the LED 22 is continued. . Instead of continuing the blinking as it is, it may be switched to lighting or dark lighting, blinking or blinking with different periods, or in this case, it may be stopped.

If no event signal indicating alarm stop is received in step S17, it is determined in step S20 whether or not there is an alarm stop operation by the alarm stop switch 20, and when the alarm stop operation is determined,
In step S21, an event signal including a serial number, a transmission source code, a group code, and an event code indicating an alarm stop is transmitted to another house alarm device. Then, the process proceeds to step S22 and an alarm sound from the speaker 58 indicating the interlock destination is output. It stops and the display by blinking of LED22 is continued. Instead of continuing the blinking as it is, it may be switched to lighting or dark lighting, blinking or blinking with different periods, or in this case, it may be stopped.

  FIG. 9 is an explanatory view showing another embodiment of the wireless residential alarm according to the present invention in which the display color of the interlocking source is different from the display color of the interlocking destination.

  In FIG. 9, the house alarm 10 is composed of a cover 12 and a main body provided behind the cover 12. A smoke inlet 16 is opened around the center of the cover 12, and a smoke detector 16 is disposed inside the cover 12. An acoustic hole 18 is provided on the lower left side of the smoke detector 16, and an alarm stop switch 20 is provided on the lower side of the smoke detector 16.

  The alarm stop switch 20 has a tact switch (not shown) arranged inside a switch cover formed of a translucent member, and in the vicinity of the tact switch inside the switch cover, as shown by a dotted line, The red LED 22a for displaying and the yellow LED 22b for displaying the link destination are arranged. When the red LED 22a or the yellow LED 22b is lit, the lighting state can be seen from the outside through the switch cover portion of the alarm stop switch 20. I have to. The other configuration is the same as that of the embodiment of FIG.

  FIG. 10 (A) shows the interlocking relationship among the residential police devices 10-1 to 10-5 of the embodiment of FIG. And the red LED 22a is turned on (first display), the fire alarm indicating the interlocking source is performed, and the remaining resident alarm devices 10-2 to 10-5 are turned on with the alarm sound and the yellow LED 22b (second display). ) Provides a fire alarm indicating the link destination.

  When the alarm stop switch 20 provided in the interlocking source home alarm device 10-1 is operated in the state of the interlocking alarm, as shown in FIG. However, the display by turning on the red LED 22a (first display) continues for a predetermined period. Moreover, the alarm sound and the display by lighting of yellow LED22b which are performed in the interlocking | destination residence alarm device 10-2 to 10-5 stop.

  As described above, the red LED 22a continues to be lit at the link source (may be lit again after a short time stop). In this case, for example, the drive current is reduced compared to the display before the alarm is stopped, and the dark LED is lit. Or may be shifted to a blinking state.

  Further, even if the interlocking source shifts to flashing with a longer cycle after the alarm stop (flashing under a driving condition with a small duty ratio), power consumption after the alarm stop operation can be suppressed. And the alarm sound which shows the interlocking destination currently performed with the interlocking | destination residence alarm device 10-2 to 10-5, and the display by lighting of yellow LED22a are all stopped.

  On the other hand, when the alarm stop switch 20 provided in any of the interlocked residence police 10-2 to 10-5 is operated, as shown in FIG. 11, the interlocked residence police 10- Although all the alarm sounds 2 to 10-5 are stopped, the alarm signal output and some display such as lighting, blinking, or blinking of the red LED 22b are continuously performed for a predetermined period for the interlocking source home alarm device 10-1.

  In this case, the display by the yellow LED 22b of the interlocking destination home alarm devices 10-2 to 10-5 continues to be lit without stopping (may be flashed again after stopping for a short time), or before the alarm is stopped. The driving method is different blinking or blinking.

  It should be noted that any home alarm device may output the interlocking source alarm sound slightly during the period until the display (history display) by the interlocking source red LED 22a is stopped. That is, after the alarm is stopped, the interlocking home alarm can perform intermittent sound output at a lower volume and / or longer period than the alarm while displaying the history by the red LED 22a.

  Thus, when the interlocking source alarm stop switch is operated during the interlocking alarm, the display of the interlocking source alarm sound, the interlocking destination alarm sound, the interlocking destination yellow LED 22b is stopped, and the interlocking source is indicated by the red LED. To display at least a predetermined period. On the other hand, if the alarm stop switch of any linkage destination is operated during the linkage alarm, all the linkage destination alarm sounds are stopped, at least the warning sound of the linkage source is maintained, and the linkage destination is red for at least a predetermined period. Some display is performed by the LED 22a.

  As a result, it can be seen that the other alarm device (link source) is still in alarm at the link destination, so the link destination alarm device where the alarm stop operation was performed is a place where the alarm sound from the link source cannot be heard. However, since the alarm sound at the interlocking destination is stopped by the alarm stop operation at the interlocking destination, safety can be ensured without being misidentified as a non-fire report or a false alarm.

  In addition, even after the alarm stop operation is completed, the history display with different display colors is performed at the link source and the link destination at least for a predetermined period (the link source may not display the history), so the fire source after fire extinguishing is specified. In addition, it is possible to easily and reliably identify a home alarm device that has issued a false or non-fire report. When an alarm stop operation is performed at the interlocking destination, the alarm sound at the other interlocking destination stops, but the alarm sound at the interlocking source is not stopped, so the interlocking source can be found by relying on the sound. Therefore, in this case, the display by the red LED may be stopped for the interlocking source.

Alarm display by the red LED22a the linkage source of home alarm 10-1 continues stopped after the time predetermined time determined by the timer setting or stop when performing the alarm stop operation again.

  In addition, although the display for identifying the interlocking source and the interlocking destination and the display for identifying before and after the alarm stop are shared by one LED, a plurality of display units may be provided and distributed as necessary.

  That is, in the system, it is only necessary to identify the interlocking source and the interlocking destination during the alarm, and each alarm device may perform some display at least for a predetermined period after the alarm stop operation. At that time, in the interlocking source, the display may be stopped without waiting for the elapse of a predetermined period after the alarm stop operation.

  In the above embodiment, the interlocking source is displayed in red and the interlocking destination is displayed in yellow. However, the interlocking source and the interlocking destination may be displayed in any different display colors. Further, the LEDs 22a and 22b may be shared by multicolor LEDs.
