INTERSCHUTZ, the world's leading trade fair for fire brigades, rescue services, civil protection and safety has now been postponed for the second time and is not scheduled to take place again until 2022. HÖRMANN Warnsysteme will definitely be there. Until then, the new products and siren systems will be presented in a different setting, including a digital trade fair folder and an intensive online consulting, because the need for advice is greater than ever.
