Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm device of a type in which a predetermined alarm sounds when a predetermined emergency push button switch such as an alarm unit is operated to issue an alarm.

[0002]

2. Description of the Related Art Conventionally, as an example of an alarm device of alarm unit type used for disaster prevention and crime prevention in a house, there are those shown in FIGS. 10 and 11, for example. These conventional ones have an emergency push button switch 1e.
The alarm unit Ae differs from the alarm unit Ae in that the alarm unit Ae is provided integrally or separately. However, in either case, when the emergency push button switch 1e is operated, a predetermined alarm output means (not activated) incorporated in the alarm unit Ae is operated. (Shown) is configured to sound a predetermined alarm.

In such an alarm device, since the continuity of the alarming operation is required, the emergency push button switch 1e is required.
Even if you press once and then release, the alarm must continue to sound. Therefore, conventionally, when the emergency push button switch 1e is pressed, the ON state of the switch is mechanically maintained. Also,
As another means, the emergency push button switch 1e is operated so that the alarm unit Ae is maintained in the alarm mode state by the electric latch function.

On the other hand, the alarm ringing for emergency needs to be stopped by the user thereafter. Therefore, the conventional alarm device is provided with the alarm stop switch 5e for stopping the alarm, but in the related art, by operating the alarm stop switch 5e, an alarm output means for making an alarm sound. Although the operation of is stopped,
The alarm mode status could not be reset.

[0005]

In the conventional emergency push button switch 1e constructed such that the ON state is mechanically maintained, even if the alarm stop switch 5e is operated, The on-state of the push button switch 1e cannot be released. In order to cancel such a state, it is necessary to return the switch button pressed by the emergency push button switch 1e to the original state, which is troublesome.

Similarly, even if the alarm unit Ae is configured to be able to maintain the alarm mode state by the electrical latch function, the alarm mode cannot be released only by operating the alarm stop switch 5e.
It is necessary to separately perform a reset operation for electrically canceling the mode. Therefore, conventionally, after the user operates the alarm stop switch 5e, it is troublesome for the user to separately reset the alarm state, and when the user forgets the reset operation, the alarm device is maintained in the alarm mode. Therefore, there is a fatal difficulty that an alarm cannot be sounded even if the emergency situation occurs again and the emergency push button switch 1e is operated.

The present invention has been proposed in view of the above points, and eliminates the need to separately perform the reset operation of the emergency push button switch and the reset operation of the alarm mode after the operation of stopping the alarm ringing is performed, and it is simple. It is possible to not only stop the alarm ringing but also to release the alarm mode properly by performing various operations, and to properly eliminate the problem that the subsequent alarm cannot be issued due to forgetting to release the alarm mode. The purpose is to provide an alarm device that can
