Alarm apparatus and alarm method
First Claim
1. An alarm apparatus comprising:
- an electric conductor disposed at a window pane;
a voltage supply device that supplies a voltage to the electric conductor;
a voltage detection device that detects the voltage of the electric conductor;
a disconnection determination device that makes a determination regarding a disconnected state of the electric conductor based on the voltage of the electric conductor detected by the voltage detection device;
an alarm determination device that determines whether or not to perform alarming based on a result of determination regarding the disconnected state of the electric conductor by the disconnection determination device; and
an alarm device that performs the alarming based on the determination by the alarm determination device, wherein the alarm determination device has an alert mode of performing the alarming if the disconnection determination device determines that the electric conductor is in the disconnected state, and a pre-alert mode of refraining from performing the alarming if the disconnection determination device determines that the electric conductor is in the disconnected state.

Abstract
An alarm apparatus includes an electric conductor disposed at a window pane, a voltage supply device that supplies a voltage to the electric conductor, a voltage detection device that detects the voltage of the electric conductor, a disconnection determination device that makes a determination regarding a disconnected state of the electric conductor based on the detected voltage of the electric conductor, an alarm determination device that determines whether or not to perform alarming based on a result of determination of the disconnection determination device; and an alarm device that performs the alarming based on the determination by the alarm determination device. The alarm determination device has an alert mode of performing if the electric conductor is in the disconnected state, and a pre-alert mode of refraining from performing the alarming if the electric conductor is in the disconnected state.

16. An alarm method comprising:
-
detecting a voltage of an electric conductor disposed at a window pane, making a determination regarding a disconnected state of the electric conductor based on the detected voltage, and determining whether or not to perform alarming based on a result of determination regarding the disconnected state of the electric conductor, wherein a pre-alert mode and an alert mode are provided for determination as to whether or not to perform the alarming, and during the pre-alert mode, the alarming is not performed even if it is determined that the electric conductor is in the disconnected state, and during the alert mode, the alarming is performed if it is determined that the electric conductor is in the disconnected state.

17. An alarm apparatus comprising:
-
an electric conductor disposed at a window pane;
voltage supply means for supplying a voltage to the electric conductor;
voltage detection means for detecting the voltage of the electric conductor;
disconnection determination means for making a determination regarding a disconnected state of the electric conductor based on the voltage of the electric conductor detected by the voltage detection means;
alarm determination means for determining whether or not to perform alarming based on a result of determination regarding the disconnected state of the electric conductor by the disconnection determination means; and
alarm means for performing the alarming based on the result of determination by the alarm determination means, wherein the alarm determination means has an alert mode of performing the alarming if it is determined by the disconnection determination means that the electric conductor is in the disconnected state, and a pre-alert mode of refraining from performing the alarming if it is determined by the disconnection determination means that the electric conductor is in the disconnected state.
