Logo DEF Network Company network of fire safety experts



Detectomat GmbH was established in 1977 and is one of the leading providers in the field of fire detection technology.

As a medium-sized company and part of the DEF Network, one of the largest independent manufacturers of fire protection system technology in Europe, we offer products and services that are built on our long time experience and our high level quality standards. Our product portfolio consists of individual components and ranges up to complex system solutions for fire detection technology and VA/PA voice alarms.

What makes us unique is that, as a specialised system provider within a large corporate group, we can offer everything from one single source.

Our parent company is the DEF Network, which is based in Massy, France. This consortium was established in 1958 by Daniel Lécuyer and has since grown to become Europe’s largest independent manufacturer of fire protection system technology. The group is now run by Philippe Lécuyer, the son of its founder.

With a strong market presence thanks to branches in ten other countries, the company is on solid ground and can guarantee flawless execution and delivery performance even on major projects. The fire detection technology developed by DEF has been used in international projects involving constructions such as the Eurotunnel and the Louvre Museum in Paris, as well as in major projects at universities, power plants and airports. These high-profile projects are a reflection of the trust placed in the DEF Network the world over.

With a decentralised, international development team of more than 130 specialists, we work to create an optimised digital framework for our products and services. We view high-performance software tools for planning, project design, programming and commissioning as a vital piece of the puzzle when it comes to cost-effectiveness and future-proof applications.

With the takeover of Simax electronics GmbH by Detectomat Systems in early 2022, the existing product range has been expanded to include voice alarm systems, the position of our company as a manufacturer of high-quality safety products for the fire alarm specialist market has been strengthened, and processes have been tailored to the requirements in Germany.


We offer high-quality and user-friendly products, as well as practical technologies and a range of services that are focused on the customer, from initial consultation through to after-sales support.
