The present invention features a self-contained, programmable, telephone-activated emergency visual alert system. Low energy consumption LED visual alert "strobe" signal is directly powered from the inventive control unit. Multiple emergency telephone numbers may be programmed into the control unit making the inventive system highly effective for use in areas without standard "911" emergency dispatch service. In an alternate embodiment, the visual indicator may be located some distance away from the controller unit and be activated by means of an rf or other wireless control link. A small, inexpensive battery at the remote indicator may power the receiver and indicating lamp for long periods of time without the need for battery replacement. Programmable integrated circuits form the basis of the control circuitry allowing low component count, low power consumption and, ultimately, low cost and long term, reliable operation. An audible alert device such as a siren may also be attached to and activated by the inventive system.
