Description

  The present invention preliminarily stores detection means for detecting a change in the external environment, calculation means for calculating the degree of change in the external environment based on a result detected by the detection means, and a plurality of selectable alarm sound signals. On / off switching between storage means and warning means for receiving a warning signal from the calculation means and notifying the change of the external environment when it is determined that the calculation means has detected a change in the external environment above the warning level. The present invention relates to an alarm device provided with a power switch section and an inspection switch section for performing an inspection for confirming the operation of the alarm means.

  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.

JP-A-9-147266 Japanese Patent Laid-Open No. 11-16068

  In the gas alarm device described above, when it is intended to have both the function of selecting the alarm sound by operating the changeover switch and the function of checking the operation of the alarm means, the two functions of the changeover switch and the check switch are provided. A switch was needed.

In addition, in the gas alarm device of Patent Document 1, it is necessary to perform an inspection operation for actually sounding an alarm sound in order to determine whether to generate a synthesized voice, a buzzer sound, or an electronic sound after switching the alarm sound. was there.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a gas alarm device capable of switching an alarm sound and checking an alarm operation with a simple structure and easily confirming the alarm sound.

  In order to achieve the above object, an alarm device according to the present invention includes a detection unit that detects a change in an external environment, a calculation unit that calculates a degree of a change in the external environment based on a result detected by the detection unit, and a selection.

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 by the inspection operation. Therefore, it is possible to immediately confirm which alarm sound signal is the switched alarm sound signal. Therefore, it is not necessary to depress the inspection switch unit again after switching the alarm sound signal, and the alarm sound can be easily confirmed.

  A third characteristic configuration of the alarm device according to the present invention includes: a detection unit that detects a change in the external environment; a calculation unit that calculates a degree of a change in the external environment based on a result detected by the detection unit; and a selectable unit Storage means for preliminarily storing a plurality of types of alarm sound signals, and an alarm signal received from the calculation means when the calculation means detects a change in the external environment that is equal to or higher than an alarm level, and is stored in the storage means An alarm device provided with alarm means for outputting any one of the alarm sound signals as sound, a power switch section for switching on and off, and an inspection switch section for executing an inspection operation for confirming the operation of the alarm means. Therefore, when the power is turned on, the power switch unit and the inspection switch unit are simultaneously pressed to switch to one of a plurality of types of alarm sound signals. , A mode, by depressing operation of the test switch portion when the relevant switching reception mode, lies in having the set control means to switch to one of a plurality of types of alarm sound signal.

According to this configuration, the switch receiving mode is set by pressing the power switch unit and the inspection switch unit simultaneously, and switching to one of a plurality of types of alarm sound signals is performed by pressing the inspection switch unit in this state. be able to.
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.

  A fourth characteristic configuration of the alarm device according to the present invention lies in that a notification means for notifying the type of the alarm sound signal after switching is provided when the alarm sound signal is switched.

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