Community Warning Systems

Public Alert Systems

Communication is one of the most critical factors in saving lives and minimizing injuries in any emergency situation, both from natural events, such as tornadoes, hurricanes, floods, and tsunamis, and from man-made accidents and threats. Effective and efficient notification systems provide essential alert and warning capabilities for preparedness and planning.

Solutions range from high-power outdoor speakers to fully integrated comprehensive regional alerting by simultaneous telephone, email, internet and audio/visual notifications. ATI’s systems provide compliance with the Department of Homeland Security and Federal Emergency Management Association regulations, helping communities to achieve their goals in emergency planning, response and preparedness.
