In 1993, HÖRMANN Warnsysteme installed the nationwide siren warning system for Singapore. With their alarm function, the sirens are at the very beginning of the warning chain. The city state attaches great importance to ensuring that the population knows what to do when the electronic sirens sound. Over the years, the system has been modernized, adapted to new requirements and maintained on a long-term basis. "The 240 electronic sirens of various power types have been in reliable use for almost 30 years now. This demonstrates the robust technology of the HÖRMANN siren and the sophisticated design concept, which stands for high reliability and durability," says Managing Director Matthias Müllner.
