  Further, although not shown in detail, an alarm sound stop switch (not shown) is mounted on the printed circuit board 30 at a set position that is turned on when the alarm sound stop button 5 is pressed, and a control unit. 31 is electrically connected.

  On the rear surface of the housing 20, the battery storage unit 7, the mounting unit 8 for fixing the fire alarm 1 to a wall material or the like, and a transmission signal output unit (not shown) for transmission output are drawn. A groove 9 for fixing wiring (not shown) is provided.

  Next, the operation of the fire alarm 1 will be described. The fire alarm device 1 of the present embodiment includes a fire occurrence monitoring function for monitoring the occurrence of a fire and an inspection function for checking various functions of the fire alarm device 1. First, the inspection function will be described.

  In the check function, the control unit 31 automatically checks various functions of the fire alarm device 1 based on the pressing operation of the alarm sound stop button 5 by the user every predetermined period and when no alarm is given. . Here, the function check of the voltage of the battery 10, the function check of the fire detection unit 2, and the function check of the wireless communication unit 32 will be described as examples.

  First, the function check of the battery voltage will be described. The control unit 31 detects the voltage applied by the battery 10 and compares it with a pre-stored battery exhaustion threshold. If the voltage level applied by the battery 10 is equal to or lower than the battery exhaustion threshold, it is determined as abnormal (battery exhausted state), and if it exceeds the battery exhaustion threshold, it is determined normal.

  Next, functional inspection of the fire detection unit 2 will be described. The control unit 31 acquires the detection voltage level output from the fire detection unit 2 and compares the detection voltage level with a preset disconnection threshold value to determine whether or not the fire detection unit 2 is disconnected. . And if the fire detection part 2 is disconnected, it will judge that it is abnormal, and if it is not disconnected, it will judge that it is normal.

  Next, a function check of the wireless communication unit 32 will be described. The function check of the wireless communication unit 32 is to check whether or not the wireless signal transmission / reception operation is normally performed between the fire alarm 1 and another fire alarm. When the fire alarm 1 transmits a radio signal, it is checked whether or not a response signal from the destination fire alarm 1 can be received. A specific operation example will be described below.

  The control unit 31 transmits a check signal for checking the function of wireless communication to other fire alarms via the wireless communication unit 32. When the other fire alarm device receives this inspection signal, it transmits a function inspection response signal to the fire alarm device 1. When the control unit 31 receives a response signal from another fire alarm device via the wireless communication unit 32, the control unit 31 determines that the wireless communication with the other fire alarm device is functioning normally.

  Here, the control unit 31 repeatedly transmits (for example, three times) the inspection signal at a predetermined time interval until a response signal from another fire alarm is received. If the control unit 31 does not receive a response signal from another fire alarm within a predetermined time even if the inspection signal is repeatedly transmitted, an abnormality occurs in wireless communication with the other fire alarm. Judge that

  Further, the control unit 31 measures the field strength of wireless communication and compares the field strength level with a preset field strength threshold to determine whether the field strength is insufficient. If the electric field strength is insufficient, it is determined as abnormal, and if it is not insufficient, it is determined as normal. The control unit 31 performs the above-described wireless communication function check in the same manner with all other fire alarms.

  By such an operation, the control unit 31 outputs an abnormality alarm if the result of its own function check is abnormal. As an output of the abnormal alarm sound, the speaker 3 outputs a voice message such as “There is an abnormality,” for example.

  As an output of the abnormality alarm display, for example, a predetermined representative display such as blinking “orange” of the representative indicator lamp 4 is performed, and a predetermined detailed display using the auxiliary indicator lamps 41, 42, and 43 is simultaneously performed. Do. Here, as the predetermined detailed display, for example, the urgency level regarding various functional inspection abnormalities is displayed using auxiliary indicator lamps 41, 42, and 43 set in accordance with the urgency level.

  Here, as the predetermined detailed display, when the voltage of the battery 10 is abnormal, for example, the control unit 31 divides the voltage level range from the battery depletion threshold value to 0 V into three ranges. The range from the battery exhaustion threshold to the first voltage level is the urgency level “low”, the range from the first voltage level to the second voltage level is the urgency level “medium”, and the second voltage level to 0V. The urgency level is set to “Large”. Then, regarding the voltage level applied by the battery 10, when the emergency level is “high”, “red” of the auxiliary indicator lamp 41 blinks once in a predetermined cycle, and when the emergency level is “medium”, the auxiliary indicator lamp 42 “Orange” is blinked once in a predetermined cycle, and when the emergency level is “small”, “green” of the auxiliary indicator lamp 43 is blinked once in a predetermined cycle.

  In addition, as a predetermined detailed display, when the fire detection unit 2 is abnormal, the control unit 31 divides the detected voltage level range from the disconnection threshold value to 0 V into three ranges, for example. Then, the range from the disconnection threshold to the first detection voltage level is the urgency level “low”, the range from the first detection voltage level to the second detection voltage level is the urgency level “medium”, the second detection voltage level The urgency level is set to “large” in the range from 0 to 0V. Then, regarding the detection voltage level output from the fire detection unit 2, when the emergency level is “high”, the “red” of the auxiliary indicator lamp 41 blinks twice at a predetermined cycle, and when the emergency level is “medium”, “Orange” of the indicator lamp 42 is blinked twice at a predetermined cycle, and “green” of the auxiliary indicator lamp 43 is blinked twice at a predetermined cycle when the emergency level is “small”.

  In addition, as a predetermined detailed display, in the case of an abnormality in the wireless communication unit 32, the control unit 31 divides, for example, an electric field intensity level range from an electric field intensity threshold value to 0 V / m into three ranges. The range from the electric field strength threshold to the first electric field strength level is the urgency level “low”, the range from the first voltage level to the second electric field strength level is the urgency level “medium”, from the second voltage level. The range up to 0V / m is set as “Urgent” “High”. With regard to the field strength level of wireless communication, when the emergency level is “high”, “red” of the auxiliary indicator lamp 41 blinks three times at a predetermined cycle, and when the emergency level is “medium”, “ “Orange” is blinked three times at a predetermined cycle, and “green” of the auxiliary indicator lamp 43 is blinked three times at a predetermined cycle when the emergency level is “small”.

In the present embodiment, in consideration of the case where there are a plurality of functional inspection abnormalities, the details of all abnormalities can be displayed by changing the number of times the auxiliary indicator lamps 41, 42, 43 blink. Alternatively, only an abnormality with a high priority may be prioritized and continuously displayed.
Moreover, the control part 31 transmits the function abnormality information (an own address, the content of the function abnormality, etc.) regarding the function abnormality detection to other fire alarms as an interlocking signal related to the function abnormality. Then, when the other fire alarm device receives the interlock signal, a plurality of fire alarm devices can be interlocked to issue a function abnormality alarm.

  In this state, when the alarm sound stop button 5 is pressed, an alarm sound stop switch (not shown) is turned on and the ON signal is input, so that the control unit 31 causes the speaker 3 to generate an alarm sound. The output of is stopped. In addition, after operation of the alarm sound stop button 5, when a fixed time elapses, normal operation is started and the inspection function is restored.

  In addition, when various functions of the fire alarm device 1 are automatically inspected based on the pressing operation of the alarm sound stop button 5 by the user, if the function inspection result is normal, the control unit 31 performs the function normal alarm. Is output. As an output of the normal alarm sound, a voice message such as “Pi is normal” is output from the speaker 3. Further, as the output of the normal alarm display, a predetermined representative display such as lighting of “orange” of the representative indicator lamp 4 is performed. Here, the detailed display using the auxiliary indicator lamps 41, 42, 43 is not performed simultaneously.

  Next, the fire occurrence monitoring function will be described. The control unit 31 acquires the detection voltage level output from the fire detection unit 2, and compares the detection voltage level with a preset fire threshold value to determine whether or not a fire has occurred in the monitoring area. . By such an operation, the control unit 31 outputs a fire alarm when a fire is detected. As an output of the fire alarm sound, the speaker 3 outputs a voice message such as “Woo Woo, Can Can, Fire, Fire”. As the output of the fire alarm display, a predetermined representative display such as blinking “red” of the representative indicator lamp 4 is performed. Here, the detailed display using the auxiliary indicator lamps 41, 42, 43 is not performed.

  Furthermore, the control unit 31 transmits fire information (its own individual address, detection level, etc.) as abnormality information related to fire detection to another fire alarm as an interlocking signal related to fire. And the other fire alarm device receives the said interlocking | linkage signal, A several fire alarm device can interlock | cooperate and perform a fire alarm.

  In this state, the above various functions are inspected, and if the inspection result is abnormal, the alarm sound stop button 5 is pushed by the user. Then, an alarm sound stop switch (not shown) is turned on, and the controller 31 stops the output of the alarm sound from the speaker 3 by inputting the ON signal. It should be noted that after a certain period of time has elapsed after the alarm sound stop button 5 is operated, normal operation is started and the fire occurrence monitoring function is restored.

  With the above configuration, the fire alarm device 1 performs the above various functional inspections every predetermined period or when the alarm sound stop button 5 is pressed, and if the inspection result is abnormal, the fire alarm device 1 uses the speaker 3. An abnormality alarm is given by the output of the abnormality alarm sound and the abnormality representative display of the representative indicator lamp 4. For example, if the voltage of the battery 10 is abnormal as a result of various functional inspections, a voice message “An error has occurred” is output from the speaker 3 and “Orange” of the representative indicator 4 flashes. To do. Furthermore, for example, when the voltage level of the battery 10 is “high” in urgency, “red” of the auxiliary indicator lamp 41 blinks once in a predetermined cycle.

  At this time, although the abnormality detail display of the auxiliary indicator lamps 41, 42, 43 is performed, it is covered by the alarm sound stop button 5 and cannot be visually recognized from the outside of the housing 20.

  Next, the user who notices this abnormality alarm presses the alarm sound stop button 5 to stop the output of the abnormality alarm sound from the speaker 3. If the user wants to confirm the details of the abnormality, the user pulls the alarm sound stop button 5 to open the opening 21 of the housing 20. Then, it is possible to confirm that only the auxiliary display lamp 41 blinks once in a predetermined cycle as the contents of the detailed display of the auxiliary display lamps 41, 42, and 43.

  As described above, at the beginning of the alarm display, only the representative display of the representative indicator lamp 4 is visible from the outside of the housing 20, and the detailed display of the auxiliary indicator lamps 41, 42, 43 is the alarm sound stop button 5. So that it cannot be seen from the outside of the housing 20. In this way, since the alarm is initially displayed as a simple alarm, the user can recognize that the fire alarm device 10 is malfunctioning without complications.

  Then, if necessary, if the user wants to know the details of the function abnormality, after the operation of stopping the alarm sound of the function abnormality by pressing the alarm sound stop button 5, the alarm sound stop button 5 is subsequently pressed. The detailed display of the auxiliary indicator lamps 41, 42, and 43 can be confirmed simply by opening the opening 21 by pulling, and the operability is good.

  In the above embodiment, the auxiliary indicator lamps 41, 42, and 43 display details before the opening 21 of the housing 20 is opened, but the opening that detects that the opening 21 has been opened. When the detection means is provided and the opening 21 of the housing 20 is opened, the auxiliary indicator lamps 41, 42, and 43 may start detailed display. Thereby, the lifetime of the battery 10 can be extended. As the opening detection means, for example, a magnet is provided below the alarm sound stop button 5, a magnet switch is provided below the corresponding opening 21, and the magnet switch is electrically connected to the control unit 31. .

  Also, an alarm sound stop switch (not shown) can be used as the open detection means. In this case, when the alarm sound stop switch (not shown) on the printed circuit board 30 is set to the upper position of the alarm sound stop button 5 when, for example, the alarm sound stop button 5 is pulled and the opening 21 is opened. What is necessary is just to set it as the setting position which a part contacts and turns on. As described above, the user can add the function that the auxiliary indicator lamps 41, 42, and 43 start the detailed display in addition to the function that stops the warning sound by pulling as the warning sound stop button 5. The operability by can be improved.

  In the above embodiment, the auxiliary indicator lamps 41, 42, 43 as the detail display unit are also used as the alarm sound stop button 5 as a cover that is normally closed from the outside of the housing 20 so as not to be visible. However, the present invention is not limited to this as long as it is a cover that can open the opening 21 by making it detachable from the housing 20.

  Further, the representative display lamp 4 as the representative display section and the auxiliary display lamps 41, 42, and 43 as the detailed display section have been described as examples. However, if the display section can display the representative display and the detailed display, the contents described above are used. It is not limited. Further, the display example of the detail display unit is not limited to the contents described above.

  For example, as the predetermined detailed display using the auxiliary indicator lamps 41, 42, 43, one of the auxiliary indicator lamps 41, 42, 43 corresponding to the urgent level of abnormality of each function check is individually blinked a predetermined number of times. However, it may be turned on. In that case, for example, an auxiliary indicator lamp that can determine the type of abnormality in function inspection based on the number of blinks may be provided separately. At this time, only when an abnormality is displayed in the function check of the wireless communication, one of the auxiliary indicator lamps 41, 42, 43 corresponding to the urgency of the abnormality corresponds to the individual address of the other fire alarm device that cannot perform the wireless communication. If it is made to blink for the number of times, the information can also be displayed.

  In addition, as a predetermined detailed display using the auxiliary indicator lamps 41, 42, 43, the urgent level of abnormality of each function check is displayed by the individual display of any one of the auxiliary indicator lamps 41, 42, 43. However, you may make it display in a bar graph form using the auxiliary | assistant indicator light 41,42,43.

  In addition, if the results of various functional inspections are normal, detailed display using the auxiliary indicator lamps 41, 42, and 43 is not performed at the same time, but detailed display is performed at the same time in the same manner as in the case of an abnormality. Also good.

  Also, as the output of the fire alarm display, only predetermined representative display such as blinking “red” of the representative indicator lamp 4 is performed, but detailed display using the auxiliary indicator lamps 41, 42 and 43 is simultaneously performed. You may make it perform. As the detailed display, for example, the detection voltage level output from the fire detection unit 2 is displayed in a bar graph using the auxiliary indicator lamps 41, 42, 43, or the detection voltage output from the fire detection unit 2 For example, the auxiliary indicator lamps 41, 42, and 43 set in accordance with the level (emergency level) are individually turned on.
