American Signal Corporation (ASC) manufactures outdoor mass notification systems. All of our warning systems are built in our world headquarters and manufacturing facility in Milwaukee, WI. Milwaukee, a traditional home to precision manufacturing services has been home to our company for more than a century. Our historic success laid the foundation for our technologically advanced products. Our mass notification warning systems are in place throughout the United States and around the world. Many have been in operation for decades; many have been installed within the last ten years as the world grows and more people are at risk of a wider variety of emergencies.
Electronic outdoor warning systems, comprised of high-powered speaker arrays (HPSA), are a growing portion of our current mass notification system deployments. Giant Voice, outdoor Emergency Voice Notification Systems (EVNS), outdoor Public Address (PA), no matter the name, HPSAs are the most effective way to broadcast warning tones and pre-recorded voice warnings. Live PA functions allow remote or local officials to issue specific warnings and directions during an emergency or an evacuation. American Signal omni-directional I-Force HPSAs are the most efficient designs built in America today. ASC E-Class HPSAs are among the most versatile and cost-effective methods to provide specific notifications to everyone in the area.
Tempest Series electro-mechanical sirens are the workhorses of ASC outdoor warning systems. These are the tone-only warning sirens used to alert the public to severe weather, fire station calls, industrial accidents; any event that requires the public to take immediate action to secure their safety. Tempest mechanical sirens generate loud, unmistakable tones that provide and immediately recognizable warnings to the public. ASC manufactures a focused line of outdoor mechanical warning sirens. We manufacture the loudest siren built in the United States. While volume alone does not constitute an effective warning, louder sirens do provide warning coverage across larger areas. This makes our loudest siren the most efficient way to warn large, up to six-mile diameter, areas. Our other sirens are more focused, effective, and appropriate for smaller areas and municipalities with higher population densities. No matter the community or facility, ASC Tempest sirens are the most effective way to warn people of an emergency.
