Abstract
The invention provides a system and method for activating one or more warning devices, such as weather warning sirens, environmental warning devices, flash flood gates, and the like, from a remote or central location. Warning devices situated across geographically dispersed areas can be remotely controlled from a central location, such as a weather center, on the basis of detected and predicted weather patterns and other environmentally hazardous events. One or more warning devices can be quickly and easily activated through a computer-implemented user interface that allows a user to select a group of warning devices that are in the path of an approaching hazardous event. Each warning device is activated through a communication line that transmits an activation code to each device. Each device provides confirmation that it has been activated, and the resulting activation is indicated on a computer screen.
