About Sonnenburg

SONNENBURG ELECTRONIC AG, headquartered in Eggenfelden in Lower Bavaria, is a manufacturer of comprehensive alerting and public warning systems. Core products include electronic sirens (SES and SDS series, 300 to 4800 watts), analog and digital siren control receivers, remote-control receivers and stationary radio systems. The sirens are made of seawater-resistant aluminium, can be configured modularly, are low-maintenance and optionally solar-powered. In addition to product manufacturing, the company offers EMS services: SMD and THT PCB assembly, device assembly, control cabinet construction, selective coating of electronic assemblies, and the development of customised electronics solutions on modern production and test facilities. The portfolio is complemented by software such as the LSR siren control centre, the alerting portal and the SESCO sound level planning tool. The alerting systems are used by municipalities, emergency services and industrial companies and are deployed in 25 countries worldwide.
