Abstract
Abstract The personal alarm security device of the present invention is a hand-held apparatus that emits a loud sound when activated. The device is shaped to be held easily in the hand, and the preferred embodiment includes an indent where the forefinger may be positioned. Using a photoelectric switch, a beam of light is projected across the indent once the device is armed for use. The device is easily armed be removing an arming pin from a receptacle in the housing. Positioning the forefinger in the indent while the device is being armed breaks the circuit, and prevents the alarm from sounding. However, once armed, when the forefinger is removed, a loud siren is activated that can only be deactivated by replacing the arming pin, allowing the battery to wear out or destroying the device.
