Challenge Electronics originated during the era when many suppliers tried to be one-stop shops for electronic components. And while many of these organizations remain in business, many more have left the business. Since its earliest days, Challenge has been a specialist in audible technology, aligning itself with the finest factory resources strategically so that it could build and maintain an infrastructure of manufacturing, distribution and value added services that is unrivaled by any other supplier in this market. The company is global supplier of sounding devices and ISO 9001:2000-certified organization.
