We've been designing and building security and communication products for over 55 years, right here in Hudson, Wisconsin. What started as Don Springer building power supplies in his basement in 1969 has grown into a lineup of more than 500 products — from emergency phones and entry systems to paging interfaces and mass notification systems. For us, "Made in the USA" isn't just a label — it's a commitment to keeping engineering, production, and support local, so we stay close to our customers and our craft.
