HÖRMANN Warnsysteme installed the nationwide siren warning system for Singapore in 1993. The sirens, with their alarm function, occupy a place right at the start of the alert chain. The city-state considers it extremely important for its residents to know what to do when the electronic sirens sound. Over the years, the system has been modernised, adapted to meet new requirements and subjected to long-term maintenance. ‘The 240 electronic sirens of various power outputs have now been in operation for nearly 30 years and are still as reliable as ever. That is a testament to the robust technology of HÖRMANN sirens and their sophisticated design delivering excellent dependability and longevity,’ said managing director Matthias Müllner.
