What is infrastructure technology

A lot of responsibility - How do I become an electronics technician for building systems?

An office complex needs a new ventilation system. Or maybe an alarm system. And what about fire protection? These are all cases for electronics technicians for building and infrastructure systems.

Jean-Pascal Wolter wants to become one of them. The 22-year-old is currently completing an apprenticeship at the Alfred Eichelberger company in Berlin. "You get around a lot and learn an incredible amount," says Wolter.

Activities range from planning an air conditioning system to regular maintenance of electronically controlled heating and ventilation systems or elevator systems to troubleshooting. "They often do the repairs themselves - or they are in close contact with other service providers," says Anja Schwarz from the Association of German Chambers of Commerce and Industry (DIHK).

Applicants are expected to be able to work in a team. "You should have technical understanding and manual skills," explains Carola Daniel from the General Association of Building Technology. Mathematical knowledge is also required - for example to calculate electrical quantities.

Above all, interested parties must be aware of the responsibility that comes with working on electronic systems and with technical systems. "If you don't work with a lot of caution and care, you not only endanger yourself, but also your colleagues," emphasizes Wolter. Strict safety regulations therefore apply to everyday work.

In practice, for example, the work goes like this: In a building complex, the escape and rescue routes, i.e. the stairwells, should remain smoke-free in the event of a fire. A so-called smoke protection pressure system is installed for this purpose. First of all, the electronics technicians need an overview plan with the existing electrical infrastructure. Then they make sketches of the planned lines, which they will lay later.

The control center of the smoke protection pressure system is a switch cabinet. This allows the system to be programmed in such a way that it automatically opens outside air and supply air flaps when a certain amount of smoke is reached.

As soon as a plant or system is installed and in operation, Wolter and his colleagues have to instruct future users on how to operate it. "To do this, they need good language and a committed demeanor," explains Daniel. Later on, the electronics technicians have to regularly inspect and maintain the systems. If malfunctions occur, then the experts also approach and go to troubleshooting.

According to the Federal Employment Agency, the apprenticeship remuneration varies: in the first year of the apprenticeship it ranges between 550 and 730 euros and then rises to around 700 to 970 euros by the last six months. The exact amount depends on the region and the company in question.

Work after your training

Electronics technician for building and infrastructure systems in electrical engineering companies, in facility management or in janitorial services. Anyone who wants to get ahead can become a master electrical engineer. The job has a future, says Daniel. Because the experts are increasingly in demand.
