  The fire sensor 11 is supplied with operating power from the battery 10 via the 4.3V power supply circuit 17. The voltage drop detection circuit 12, the display device 14, and the speaker device 15 are supplied with operating power from the battery 10 through the 3.2 V power supply circuit 18.

  Next, the battery connection notification processing operation of the fire alarm device 1 having the above-described configuration will be described below with reference to the flowchart of FIG.

  First, the battery 10 is connected to the fire alarm device 1 at the time of construction (step S1), and supply of operation power to the fire alarm device is started. Thereby, the operation of the circuit shown in the block diagram of FIG. 2 is started (step S3), and then self-diagnosis for checking the presence / absence of each part in the fire alarm device 1 is started (step S5).

  Next, a fire signal from the fire sensor 11 is input to the CPU 13a (step S7). Next, the input fire signal is converted into digital data, and it is determined based on the value of this digital data whether or not the fire sensor 11 has failed (step S9). If the fire sensor 11 has not failed (No in step S9), the process proceeds to step S11. If the fire sensor 11 has failed (Yes in step S9), the process proceeds to step S19.

  In step S11, it is determined whether or not the speaker in the speaker device 15 is disconnected. If the speaker is not disconnected (No in step S11), the process proceeds to step S13. If the speaker is disconnected (Yes in step S11), the process proceeds to step S19.

  In step S13, it is determined whether or not a voltage drop of the battery 10 has occurred. If the battery voltage drop has not occurred (No in step S13), the process proceeds to step S15. If the battery voltage drop has occurred (Yes in step S13), the process proceeds to step S19.

In step S 15, the result of the diagnosis by steps S9 to S13, since there is no fault anywhere, it is determined that the self-diagnosis OK. Next, both the alarm lamp 14a (red LED) and the alarm lamp 14b (green LED) of the display device 14 blink (or turn on) for a short time (for example, 1 second), and beep sound (for example, from the speaker device 15). ) Beeping for a short time (step S17). Next, the process is completed, and then the operation shifts to the normal operation mode of the fire alarm device 1, but the description is omitted.

  As described above, when the self-diagnosis result is OK, the alarm lamp 14a (red LED) and the alarm lamp 14b (green LED) of the display device 14 are displayed by blinking and the confirmation sound by the beep sound from the speaker device 15 is displayed. Since the notification by both occurs for a short time, the installer can confirm both the visual and auditory senses that the self-diagnosis is OK and the battery connection is correctly performed.

  On the other hand, in step S19, the self-diagnosis result is determined to be NG due to the failure of the fire sensor 9 and / or the occurrence of any abnormality such as disconnection of the speaker and / or battery voltage drop. Next, the alarm lamp 14b (green LED) of the display device 14 starts blinking (step S21). Next, it is determined whether or not the switch SW1 is turned on (step S23). While the alarm lamp 14b (green LED) of the display device 14 is blinking, if the pull string is pulled and the switch SW1 is turned on (Y in step S23), then the alarm sound from the speaker device 15 is output. Generation is started (step S25).

  For example, when the fire sensor 11 is out of order, this alarm sound generates an alarm by a beep sound “Pipi” and a voice message “Need to check. Please contact the dealer”. Further, no alarm sound is generated when the speaker device 15 is disconnected. When a battery voltage drop occurs, an alarm with a beep sound and a voice message “Battery is dead. Please contact your dealer” are generated. These voice messages are sequentially generated to inform the reason for the self-diagnosis NG every time the drawstring is pulled and SW1 is turned on.

  Therefore, when the installer confirms that the warning lamp 14b (green LED) blinks and finds that some abnormality has occurred, the contractor pulls the pull string of the switch SW1 to obtain a voice message about the content of the abnormality. It can be confirmed by the presence or absence.

  As described above, when the self-diagnosis result is NG, the installer first knows that an abnormality has occurred by visually blinking the alarm lamp 14b (green LED) of the display device 14, and then pulls the switch SW1. Since the alarm sound is generated from the speaker device 15 by pulling the sound, the content of the abnormality can be confirmed by hearing, so that a treatment corresponding to the content can be performed.

  After the above-described process for confirming the battery connection of the fire alarm device 1, if a fire is detected in the normal operation mode, the alarm lamp 14 a (red LED) of the display device 14 is turned on and the speaker device 15 An alarm sound, for example, an alarm with a beep sound “Pi Phi Phi Phi” and a voice message “Fire is fire.

  As described above, the best mode of the present invention has been described, but the present invention is not limited to this, and various modifications and applications are possible.

  For example, in the above-described embodiment, both the display device 14 and the speaker device 15 are operated in step S17. However, the present invention is not limited to this, and only one of them may be operated.

  Moreover, although the case where it applied to a fire alarm is demonstrated in the above-mentioned embodiment, this invention is not limited to this, It is applicable also to a gas leak alarm.
