Auer Signal was founded as J. Auer Fabrik elektrischer Maschinen by Johann Auer in Vienna in 1910. The company initially produced electric drive motors.

In 1938, the son of Johann Auer, Hubert Auer, started the production of motor sirens.

In 1978, he handed over the management to his sons Georg and Michael Auer, who developed the first explosion-proof signal devices and telephones for the industry.

In 1986, they also began to produce optical and acoustic signalling devices. The strong growth led to the foundation of a German sales company in 2001. In the following years, the international sales structure was built up. Today the company is represented worldwide.

In 2007, a new, modern production site was built and opened in Perfektastrasse 102.

In 2015, Christian Auer and his sister Antonia Korger took over the management of J. Auer in the fourth generation.

In 2017, they changed the company name to Auer Signal.
