Fire unites transnational market leaders in structural fire protection: the companies in the group - including Multimon as the nucleus - usually project fire protection systems on a turnkey basis, i.e. they supply everything from one source, from planning to installation and commissioning. The systems are mainly used in high-rise buildings, shopping centres, warehouses, production facilities, logistics centres, underground garages or in listed buildings. They consist of fire alarm systems and various fire extinguishing equipment, such as sprinkler systems as well as systems using water mist, gas or foam to fight fires. The companies of Fire Holding are among the suppliers that can deliver all essential systems. The components of the systems are mainly not produced by the companies themselves, but are purchased from other manufacturers. The essential know-how lies in the efficient and rule-compliant design, installation and maintenance of the systems. Fire protection regulations are increasing, and systems that are already installed must be regularly maintained and upgraded if necessary.

The group maintains (as of June 2021) more than 20 locations in Germany and in Eastern European countries. Almost 80 per cent of the turnover is generated in Germany, the most important foreign market is Poland with about 16 per cent of the turnover.
