Dadonville, France
SEFI is a company founded in Pithiviers in 1970 and specialized in the production of security installations. The main activity of the firm was originally subcontracted work in electronics, but since 1976 SEFI has been part of Réseau DEF, a network of companies distinguished with fire protection systems. In 1999, the company expanded by setting up a research and development facility in Massy, where today 30 employees are active. The production of modern systems is located in the new, energy-efficient building in Dadonville (45). SEFI develops and produces the latest security installations as well as maintains older systems. The company specializes in the manufacture of ESC-Systems and CMSI-Centralizers, which for example control fire suppression and evacuation.
