Detectomat GmbH

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 many years of experience and our exacting quality standards.

Our product portfolio ranges from individual components right the way up to complex system solutions, all directly from the manufacturer. At the headquarters of Detectomat Systems GmbH in Ahrensburg, Germany, we develop, produce and distribute products that meet the needs of the market.

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 headed up 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 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.


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
