The story of Calectro began in 1969, when a young Swedish engineer by the name of Karl Johan Pettersen returned from a position in Denmark and began importing components for the building automation industry. His company grew steadily throughout the 70s and 80s, a time of numerous changes to fire safety legislation in Sweden and the rest of Europe. And by the end of the 1980s, Calectro was successfully supplying industrial and building automation clients in Sweden with various detectors, sensors and related equipment.
Calectro started with duct smooke detectors back in 1978, with a two tube system.This became a very important product for our company. We have always tried to be innovative, to listen to what our customer wants and to lead the development in our market segments. In 1994, we therefor developed our first Uniguard one-tube-solution. We are very proud of how revolutionary our product was then and still is today.
