It started in 1942, in the wake of a World War—American Signal Corporation (ASC) made a pledge to the world to provide first alert and early warning technologies, to ultimately save lives. Our air raid sirens and speaker arrays were the first step to creating a safer world and today, while our technologies have certainly evolved, our mission has stayed the same.

ASC has been an industry leader in mass notification since the beginning.  Our air raid sirens paved the way for giant voice systems, which heralded digital alerts and today’s integrated systems. We’ve seen the evolving need for innovation in our industry and have been influencers in how these technologies have developed over time.

Core values are principles that guide an organization’s internal conduct as well as its relationship with the external world.

American Signal Corporation and its employees have adopted the following principles that we esteem as an organization, they are the philosophical foundation of our corporate ideology.  These are the core values that we hold dear and use to make decisions and guide our individual behaviors.

  • Be the absolute best at what we do today – American Signal Corporation faces the challenges presented by rapid growth.  Throughout our evolution operational excellence is expected at all times.  We must be the best today.  Each employee plays an equally important role in establishing and preserving this core value.  Be the absolute best you can be today.
  • Be the innovators of tomorrow’s solutions – Innovator – a person who introduces new methods, ideas, or products.  American Signal Corporation must not only provide the highest quality products and services for our markets, but we must continuously innovate.  We need to out-think, out-engineer, and out-deliver our competition.
  • Accept no defects, create no defects, and pass no defects – By accepting no defects we hold suppliers and upstream processes accountable and allow zero defects to enter our operation, by holding ourselves individually responsible for producing zero defects we prevent the introduction of defects, by self-assessing and through rigorous quality assurance we shall allow no defects to pass down stream and ultimately to our clients.
  • Remember that everyday lives depend on our products – Our mass notification and early warning products save lives.  As there is no value to place on human life, there is no limit to our expenditure on quality and reliability in our designs and manufacturing.  We must produce as if our own lives depend on our own performance.
