An apparatus (20) provides an emergency alert function that detects redundant notifications of emergency events. According to an exemplary embodiment, the apparatus (20) includes a signal receiving element (21) operative to receive first emergency alert signals representing a first notification of a first emergency event and second emergency alert signals representing a second notification of a second emergency event. A processor (27) enables an alert output responsive to the first emergency alert signals. The processor (27) suppresses the alert output responsive to the second emergency alert signals if at least two predetermined conditions are satisfied. The at least two predetermined conditions include the first emergency event being a same type of event as the second emergency event, and the first emergency event having an expiration time within a predetermined time period before or after an expiration time of the second emergency event. ® KIPO & WIPO 2008
