Nature is becoming increasingly erratic, demonstrating its power through natural elements threatening our planet. Disaster scenarios are written almost daily, affecting people regardless of their location, status, or preparedness for what is to come. Early warning and notification systems include acoustic warning components, primarily electronic sirens and monitoring systems with sensors. Thanks to these components, they can essentially eliminate losses, at least in human lives.

Why build a system to warn of natural hazards
Nature is becoming increasingly erratic, demonstrating its power through natural elements threatening our planet. Disaster scenarios are written almost daily, affecting people regardless of their location, status, or preparedness for what is to come. Early warning and notification systems include acoustic warning components, primarily electronic sirens and monitoring systems with sensors. Thanks to these components, they can essentially eliminate losses, at least in human lives.
Warning system description
Telegrafia’s early warning systems for natural disasters (tsunamis, fires, tornadoes, volcanic eruptions, or earthquakes) are designed as state-of-the-art systems, covering large and rugged areas with sirens. They can be interfaced with a variety of existing weather, underwater earthquake, sea level, or river level monitoring systems. The systems are equipped with the Vektra® software application modules for the individual system elements (Warning, Notification, and SCADA). When the Vektra® SCADA software detects a problem or hazard, all sirens are automatically activated by the Vektra® Warning application. At the same time, the competent persons, most commonly the first responders or emergency response workers, are informed by a voice or text message of the occurrence of an emergency by the Vektra® Notification application.
Early warning systems for tsunamis, tornadoes and other natural hazards include:
- Monitoring system
- Control centre
- Pavian electronic sirens
- Communications infrastructure
- Notification

Advantages of the solution
- Wide area coverage in any environment thanks to the reliability of electronic sirens and the strength of their acoustic warning signal
- Direct connection of sensors and sirens without additional hardware
- Possibility of using data obtained from meteorological and hydrometeorological stations and their automatic evaluation
- Automated control of other SCADA devices based on monitoring outputs (e.g. shutting off the gas supply)
- Automatic activation of early warning and notification
- Simplification of the evacuation process thanks to the possibility of live announcements, text-to-speech function, and excellent intelligibility of the spoken word
- Playback of audio recordings from the siren memory or external sources
- Intelligent operation thanks to silent siren tests, remote self-diagnostics, and the possibility of interfacing with third-party systems
- The full operation, even in the event of a power failure using solar panels
