Kirchseeon, 21 July 2020 - Covid-19 may partially paralyze the economy, but natural disasters do not prevent the virus. The need for electronic sirens from HÖRMANN Warnsysteme remains little affected by this crisis. The team of the siren pioneer continues to supply and support customers as before the crisis. After all, if sirens are needed, they must be delivered quickly and once they are installed, they must work. The bigger problem for the company is the shortage of staff.
