An alarm device includes a first portion housing an alarm component for producing an audible sound upon actuation in response to an alarm event and a second portion housing a vibration-inducing component for producing shaking movement in the device upon actuation in response to an alarm event. The first and second portions are pivotably engaged with one another to permit swiveling movement of one of either the first or second portion relative to the other portion. The first and second portions are pivotable between a first position, wherein opposing surfaces of each of the first and second portions are substantially fully aligned with one another, and a second position, wherein opposing surfaces of each of the first and second portions are substantially exposed.
