France
Ensuring safety, Fire detection, Gas extinguishing
ASD is the French distribution subsidiary of the DEF Network. With the support of qualified, trained partners, our aim is to be the leading manufacturer in the French market, offering a complete range of fire safety products and services.
Over 25 years of experience
Created in 1997, ASD’s mission is to distribute electronic fire safety products to its network of referenced partners nationwide.
In 2023, ASD is diversifying and integrating EXTINCTIUM’s business to offer you complete, made-to-measure automatic gas extinguishing systems.
As a recognised training organisation (Qualiopi accreditation obtained in 2021), ASD is able to train its partners’ technical teams in the design, programming, commissioning and maintenance of its products. ASD also provides a technical hotline to help its partners with complex on-site operations.
ASD’s concept direct from factory offers a twofold advantage: the partner is autonomous in terms of product installation, and the operator is free to choose the partner it wishes to work with.
