Abstract
An alarm device includes a first detecting unit and a controlling unit. The first detecting unit has an isolating circuit, a first enabling circuit, a second enabling circuit and an output circuit. The isolating circuit generates an adjusting signal according to an input signal. The first enabling circuit generates a first enabling signal according to the adjusting signal. The second enabling circuit generates a second enabling signal according to the first enabling signal. The output circuit outputs a first detecting signal according to the second enabling signal. The controlling unit outputs a control signal according to the first detecting signal. The control signal controls an electronic device to operate under a standby mode when the first detecting signal refers to an abnormal status.
