Clearly spoken words instead of unfamiliar sounds

In difficult, unfamiliar and confusing situations, the spoken word has a major advantage: An electro-acoustic speaker system enables you to speak directly to building occupants. This prevents a lack of attention and eliminates misinterpretations from the start. Clear instructions make it possible to quickly prompt large groups of people to save themselves, gaining valuable minutes.

Reduction in response times (BS DD 240-1 study)

If people are able to save themselves in time, this can have a positive impact on further actions by emergency personnel. When emergency responders find an almost empty building, they can immediately take the necessary measures without having to first account for the building’s occupants. Saving lives always has the highest priority.

Buildings with large groups of people pose a special challenge. These include:

  • Hotels

  • Government buildings

  • Shopping centers

  • Schools

  • Universities

State-of-the-art voice alarm systems from Siemens are optimized for such applications. The systems provide clear and intelligible announcements about the danger and give precise instructions that are immediately understood. These announcements can initially be stored texts. During the intervention, they can be supplemented by live announcements from emergency personnel in specific areas of the affected building complex.
