Sirens can be mounted on or near government buildings, on tall structures such as water towers, as well as in systems, where several sirens are distributed around a town for better sound coverage. Some newer sirens are electronically driven by speakers.</SPAN></SPAN></P><P /><P STYLE="margin:0 0 0 0;"><SPAN>During World War II in the wake of Pearl Harbor, thousands of sirens warned hundreds of thousands of US combatants, support personnel, and civilians living in the Pacific theater. Since the end of the war, tens of thousands of sirens have been deployed in all 50 states, and 60 countries across a broad range of military and government facilities, industries, and communities to provide mass notification to tens of millions of people. Most sirens give a rotational-directional, 360 degree sound coverage pattern.</SPAN></P></DIV></DIV></DIV>
