The detection processing unit 4A detects a fire and a gas leak from the detection results of the fire detection unit 2 and the gas detection unit 3.

  The alarm processing unit 4B controls the display output unit 7 and the audio output unit 8. When a fire or a gas leak is detected by the detection processing unit 4A, the alarm processing unit 4B controls the display output unit 7 and the audio output unit 8 to generate a display alarm and an audio alarm informing that.

  The external output processing unit 4C causes the external output transmission unit 9 to output various types of information such as a fire or gas leak alarm. The storage unit 4D is composed of the RAM, ROM, etc., and stores data necessary for the processing of the microcomputer 4. That is, the fire detection unit 2, the gas detection unit 3 and the microcomputer 4 constitute an abnormality detection / alarm means. The switch processing unit 4E detects on / off of a switch element 13B that constitutes a voice switch 13 described later.

  As shown in FIG. 2, the fire detection unit 2, the gas detection unit 3, the microcomputer 4, the LED 5, the speaker 6, the display output unit 7, and the audio output unit 8 are mounted on the wiring board 10 and accommodated in the case 11. ing.

  Further, as shown in FIG. 1, the composite alarm device 1 converts an AC plug P for connection to an AC power source and an AC power source from the AC plug P into a direct current to generate a fire detection unit 2 and a gas detection unit 3. , Microcomputer 4, LED 5, speaker 6, display output unit 7 and audio output unit 8 (hereinafter abbreviated as “microcomputer 4 etc.”), and an operation means for turning on / off the audio alarm And an audio switch 13.

  As shown in FIG. 2, the voice switch 13 protrudes from the back surface of the case 11 and is slidable between an ON side (ON position) and an OFF side (OFF position), and the knob 13A is on the ON side. And a switch element 13B that is turned on when the knob 13A is on the OFF side. The user can perform a switching operation by sliding the knob 13A.

  The switch element 13B is mounted on the wiring board 10. The switch processing unit 4E of the microcomputer 4 can detect whether the voice switch 13 is on or off by monitoring the on / off state of the switch element 13B.

  Next, the operation of the composite alarm device 1 configured as described above will be described with reference to the flowchart shown in FIG. The composite alarm device 1 configured as described above is shipped with the knob 13A of the voice switch 13 set to the ON side when shipped from the factory.

  When the AC plug P is connected to an outlet, power is supplied from the power supply unit 12 to the microcomputer 4 and the like. In response to this power supply, the microcomputer 4 starts the process shown in FIG. 3 and enters a fire and gas leak monitoring state. When power is supplied, the microcomputer 4 acquires detection results from the fire detection unit 2 and the gas detection unit 3 (step S1). Next, when the microcomputer 4 detects a fire or a gas leak based on the detection result acquired in step S1 (Y in step S2), the microcomputer 4 turns on the LED 5 and generates an alarm sound from the speaker 6 to thereby generate an audio alarm and Both display alarms are generated (step S3).

  In response to the generation of this alarm, the user slides the knob 13A of the voice switch 13 to the OFF side. When the microcomputer 4 detects that the voice switch 13 is switched from the ON side to the OFF side during the generation of the voice alarm and the display alarm (Y in step S4 and Y in step S5), the voice alarm is stopped and displayed. After continuing the alarm (step S6), the process proceeds to step S8. Also, if the switching operation from the ON side to the OFF side of the voice switch 13 is detected while the voice alarm is stopped and only the display alarm is generated (Y in step S4 and N in step S5), the voice alarm is generated again. (Step S7), the process proceeds to Step S8. On the other hand, if the switch from the ON side to the OFF side of the voice switch 13 is not detected (N in step S4), the microcomputer 4 does not proceed to step S6, so both the voice alarm and the display alarm are continued. In the state, the process proceeds to step S8.

  In step S8, the microcomputer 4 acquires the detection results from the fire detection unit 2 and the gas detection unit 3 again. If the fire and gas leak continue based on the acquired detection result (Y in step S9), the microcomputer 4 returns to step S4. On the other hand, when the fire and the gas leakage have not continued (N in step S9), the microcomputer 4 stops all alarms (step S10) and then returns to step S1.

  On the other hand, if no fire or gas leak has occurred based on the detection result acquired in step S1 (N in step S2), the microcomputer 4 determines whether or not the voice switch 13 is on the OFF side ( Step S11). If it is OFF (Y in step S11), the microcomputer 4 counts up the count value T of the timer (step S12). On the other hand, if the microcomputer 4 is ON (N in step S11), the microcomputer 4 resets the count value T of the timer to 0 (step S15) and then stops if a notification in step S14 described later is output. (Step 16), the process returns to Step S1. As a result, the count value T of the timer is a duration time in which the voice switch 13 is set to the OFF side and no abnormality is detected.

  As a result of counting up, when the count value T reaches a predetermined time or more (Y in step S13), the microcomputer 4 keeps the state where the voice switch 13 is OFF and no abnormality is detected for a predetermined time or more. It is determined that the voice switch 13 is functioning as a notification unit, and the LED 5 and the speaker 6 are controlled to notify that the voice switch 13 is on the OFF side (step S14). For example, “sound switch 13 is still OFF. Please return to ON” is output from speaker 6. Thereafter, if the voice switch 13 is turned on (N in step S11), the timer count value T is reset to 0 (step S15), and the notification that the voice switch 13 is turned off is stopped ( Step S16), returning to step S1.

  According to the composite alarm device 1 described above, by operating the audio switch 13, only the audio alarm can be stopped. Thereby, the user can stop only the troublesome voice alarm easily by operating the voice switch 13.

  Further, according to the composite alarm device 1 described above, when the state is changed from a state in which no abnormality is detected to a state in which an abnormality is detected (Y in step S2), regardless of the position of the voice switch 13 (the voice switch 13 is turned off) In both cases, both an audio alarm and a display alarm are output (step S3). Thereby, after the voice switch 13 is turned OFF and the voice alarm is stopped (step S5), for example, the insecticide or alcohol adhering to the activated carbon evaporates and the detection of the abnormality is not continued (N in step S9). After the alarm is stopped (step S10), when an abnormality is detected again (Y in step S2), both an audio alarm and a display alarm can be generated (step S3), and the user is surely notified of the abnormality. be able to.

  Further, according to the composite alarm device 1 described above, when the voice switch 13 is switched from the ON side to the OFF side while both the voice alarm and the display alarm are generated (Y in step S4 and Y in step S5), the microcomputer 4 Stops only the audio alarm. In this state, if the abnormality detection is continued, the display alarm is continued. Thereby, when a false alarm occurs, the user can easily stop only the troublesome voice alarm by switching the voice switch 13 from the ON side to the OFF side.

  Further, according to the composite alarm device 1 described above, when the audio switch 13 is switched from the ON side to the OFF side while the audio alarm is stopped and only the display alarm is generated (Y in step S4 and N in step S5), the microcomputer 4 generates a sound alarm again. As a result, even when the voice alarm is stopped, the user can generate the voice alarm again by a simple switch operation, can know why the composite alarm device 1 was warning, opened the window and ventilated. Appropriate measures can be taken.

  In the state described above (when the voice switch 13 is on the OFF side and both the voice alarm and the display alarm are generated), the voice switch 13 is switched from the OFF side to the ON side, and then from the ON side to the OFF side. Is switched to Y in step S4, and the voice alarm can be stopped again.

  Further, according to the composite alarm device 1 described above, the microcomputer 4 indicates that the voice switch 13 is in the OFF side when the voice switch 13 is in the OFF side and no abnormality is detected for a predetermined time or longer. The effect is notified using the LED 5 and the speaker 6 (step S14). Thereby, the user can be made aware that the voice switch 13 remains in the OFF side, and the user can switch the voice switch 13 to the ON side which is the original position.

  According to the above-described embodiment, the duration of the state in which the voice switch 13 is in the OFF side and no abnormality is detected is counted using a timer. However, the present invention is not limited to this. Absent. For example, the composite alarm device 1 has a built-in energization timer that counts the energization time, but the duration may be obtained from the count value of the energization timer.

  Moreover, according to embodiment mentioned above, although it was the composite alarm device 1 which alarms a gas leak and a fire, it is not restricted to this. For example, the present invention may be applied to a gas alarm that warns only of a gas leak or may be applied to a fire alarm that warns only of a fire. It is also conceivable to apply it to a CO alarm that warns of the occurrence of carbon monoxide.

  Further, according to the above-described embodiment, the voice switch 13 is a slide switch that can be switched between the ON side and the OFF side, but is not limited to this. It is also possible to use a push switch or the like.

  Moreover, according to embodiment mentioned above, although the composite alarm device 1 received the power supply from the electrical outlet, it is not restricted to this. For example, a battery may be built in the composite alarm device 1, and power may be supplied from the battery.
