  With conventional gas alarms such as gas leak alarms and incomplete combustion alarms, even when home gas alarms and commercial gas alarms with different installation targets have the same level of environmental resistance performance The alarm sound may be different for home use and business use. For this reason, for example, a home gas alarm that emits a voice synthesis sound and a business gas alarm that emits a buzzer sound or an electronic sound may be handled as different models.

  Patent Document 1 stores in advance a plurality of selectable alarm sound signals determined in accordance with an installation target by the alarm sound storage means, and uses an alarm command as a selection signal for the plurality of types of alarm sound signals. A gas alarm with a changeover switch is described. That is, the gas alarm device of Patent Document 1 can provide a gas alarm device having compatibility with a home gas alarm device and a commercial gas alarm device by switching the alarm method.

  In this way, since the alarm sound can be selected by operating the changeover switch, the type of the alarm sound is different, so that one type of gas leak alarm device that conventionally required two models for home use and one for business use is combined. Was possible.

  Also, in general, the function of a gas alarm should be checked regularly or at any time during and after the installation of a gas alarm so that the alarm can be reliably issued when an alarm is required. Is required.

  Patent Document 2 discloses a gas alarm device including an inspection signal generating unit that generates a signal for causing the alarm unit to perform the same operation as the operation performed by the alarm unit by the determination of the alarm determination unit in response to a manual operation of the inspection start operation unit. Is described. By observing a series of operations in this way, the operation of the alarm means can be checked.

A city gas sensor can detect a leak gas such as hydrocarbon gas, an LP gas sensor can detect LP gas, and a CO sensor can detect carbon monoxide gas generated by incomplete combustion. A type sensor element or a catalytic combustion type gas sensor element can be used. As the fire sensor, a temperature sensor that senses an increase in temperature, a known scattered light smoke sensor having a smoke sensing function, or the like can be used. This embodiment demonstrates the case where it is set as the alarm device X as the gas alarm device which applied the city gas sensor as the detection means 10. FIG.

(Calculation means)
The calculation means 20 includes a concentration calculation unit that calculates the city gas concentration based on the output of the detection means 10 detecting the leakage of the city gas. The concentration calculation unit may use a microcomputer that can calculate the city gas concentration based on the output signal from the detection means 10.

  The calculation means 20 controls the alarm means 40 to send an alarm signal S1 to the alarm means 40 and issue an alarm by the alarm means 40 when the detection means 10 continuously detects the city gas concentration above the alarm level.

(Memory means)
As long as the memory | storage means 30 is a memory and storage which can memorize | store multiple types of alarm sound signals, what kind of aspect may be sufficient as it. In the storage means 30, as a plurality of types of alarm sound signals, for example, a synthetic sound signal required by a home gas alarm device (for example, a synthetic voice such as “Does gas leak?”) It is good to memorize | store two types of electronic sound signals (for example, electronic sounds, such as "beep, a beep, a beep, a beep") required by an alarm device. The number of alarm sound signals to be stored may be two or more, and the forms of synthesized speech and electronic sound may be other than the above.

(Alarm means)
When the calculation means 20 determines that the detection means 10 has continuously detected the detected gas concentration equal to or higher than the alarm level, the alarm means 40 receives the alarm signal S1 from the calculation means 20 and selects the selected alarm sound signal. A warning is issued by voice based on In the present embodiment, the alarm means 40 is constituted by a speaker and its drive circuit, and converts the alarm sound signal S2 into an alarm sound S3 and outputs it.

(Power switch part)
The power switch unit 50 may be in any form as long as it is a switch-like member capable of switching the alarm device X on and off.

(Inspection switch)
The inspection switch unit 60 may be in any form as long as it is a switch-like member that executes an inspection operation for confirming whether the alarm means 40 operates normally.
The check operation checks whether the same operation as the operation performed by the alarm unit 40 can be reproduced when the calculation unit 20 determines that the detection unit 10 continuously detects the detected gas concentration equal to or higher than the alarm level. . For example, when the inspection switch unit 60 is turned on, an alarm signal S1 is sent from the arithmetic means 20 to the alarm means 40, and it is confirmed whether or not a sound based on the selected alarm sound signal is emitted from the alarm means 40. it can. At this time, if it can be confirmed that a desired sound is being emitted, the operator can recognize that the alarm device X is operating normally.

(Control part)
The control means 70 is set to switch to one of a plurality of types of alarm sound signals by simultaneously pressing the power switch unit 50 and the inspection switch unit 60 when power is turned on.
When the pressing operation is performed, the control means 70 outputs the warning sound signal S2 of either the synthesized sound signal or the electronic sound signal selected by switching to one of a plurality of types of warning sound signals to the warning means 40. It is set so that it can output toward In this state, when the alarm signal S1 is sent from the arithmetic means 20 to the alarm means 40, the control means 70 controls so that the alarm sound signal S2 is sent to the alarm means 40 to issue an alarm.

  In the alarm device X of the present invention, when the alarm sound signal of the alarm device X is switched, the power switch unit 50 and the inspection switch unit 60 are simultaneously pressed to select one of a plurality of types of alarm signal. You can switch to In this configuration, the structure of the alarm device X can be simplified because the dedicated changeover switch for selecting the alarm sound can be omitted.

  The control means 70 may be set to execute the inspection operation when the alarm sound signal is switched.

  In this configuration, the inspection operation can be performed when the alarm sound signal is switched, that is, when the power switch unit 50 and the inspection switch unit 60 are pressed simultaneously. Thereby, simultaneously with switching to one of a plurality of types of alarm sound signals, a sound based on the selected alarm sound signal is emitted from the alarm means 40 by the inspection operation. Therefore, it is possible to immediately confirm which alarm sound signal is the switched alarm sound signal.

[Another embodiment 1]
In the above-described embodiment, when the alarm sound signal of the alarm device X is switched, the power switch unit 50 and the inspection switch unit 60 are simultaneously pressed when the power is turned on, so that any one of a plurality of types of alarm sound signals can be selected. It was set as the aspect which can be switched to. However, the present invention is not limited to such a mode, and the control unit 70 can be switched to one of a plurality of types of alarm sound signals by simultaneously pressing the power switch unit 50 and the inspection switch unit 60 when the power is turned on. It is possible to switch to one of a plurality of types of alarm sound signals by pressing the inspection switch unit 60 in the switching acceptance mode.

In this configuration, by simultaneously pressing the power switch unit 50 and the inspection switch unit 60, for example, the switching acceptance mode is set only for a predetermined time, and by pressing the inspection switch unit 60 within the predetermined time, a plurality of operations are performed. It can be switched to one of the types of alarm sound signals. On the other hand, if the control means is set so that the switching acceptance mode is canceled when a predetermined time elapses, the alarm sound signal cannot be switched even if the inspection switch unit 60 is pressed after the switching acceptance mode is canceled. Can be configured.
As a result, during the switching acceptance mode, a plurality of types of alarm sound signals can be selected at any time, so that the alarm sound signal can be reliably selected.

[Another embodiment 2]
In the embodiment described above, a notification means (not shown) for notifying the type of the warning sound signal after the switching may be provided when the warning sound signal is switched.
The notification means may be configured to recognize which alarm sound signal (for home use or business use) is visually or audibly, for example. The visually recognizable notification means may be configured to determine the type of alarm sound selected by, for example, a lamp display such as an LED. The notification means that can be recognized by hearing may be configured to notify the type of alarm sound by voice by pressing a switch or the like at a desired timing when the alarm device X is operating.

  With this configuration, when the operator wants to confirm the type of alarm sound, it can be confirmed immediately.
