Electronic siren early warning systems are becoming a key part of modern civil protection infrastructure, delivering fast and reliable alerts to the population. In SG Mittelweser, Germany, a recent project demonstrates how electronic siren early warning systems can significantly improve emergency communication and public safety.
Several Gibon 600 W electronic sirens were installed across the municipality to expand the coverage of the local public warning system. These outdoor sirens provide immediate acoustic alerts and voice messages, ensuring that residents receive timely warnings during emergencies such as natural disasters or critical incidents. The system supports local authorities in protecting lives and improving overall emergency preparedness.
Electronic Siren Early Warning System in Modern Civil Protection
The Gibon 600 W siren represents the fourth generation of Telegrafia’s electronic sirens. All generations are already deployed across Germany, demonstrating long-term reliability and continuous innovation in early warning technology.
Designed for outdoor use, the Gibon 600 W combines powerful sound output with advanced digital features, making it a key component of modern emergency alert systems.

Key Features of Gibon 600 W Electronic Sirens
Wide Coverage with Four Loudspeakers
The Gibon 600 W electronic siren is designed to provide consistent and effective coverage across large areas. Equipped with four integrated loudspeakers, it ensures uniform sound distribution, allowing warning tones and voice messages to reach the entire community clearly and reliably. This wide coverage is essential for delivering timely alerts in critical situations.
Reliable Power Supply with Backup
The system operates on standard AC mains power and includes a built-in battery backup (2 × 12 V). This ensures continuous operation even during power outages, allowing the siren to deliver reliable alerts when they are needed most. Such redundancy is a key factor in modern early warning systems.
Clear Voice Messages with Digital Processing
Advanced digital signal processing (DSP) enables precise reproduction of alarm tones and voice announcements. High speech intelligibility ensures that emergency instructions are clearly understood by the population, even in noisy or stressful environments. This significantly improves the effectiveness of emergency communication.
The system supports:
- pre-recorded warning tones
- live voice announcements
- programmable alarm scenarios and priorities
Weather-Resistant Design (IP56)
The control unit is housed in an IP56-rated enclosure, providing reliable protection against dust and high-pressure water. This ensures stable and continuous operation of the siren in demanding outdoor conditions, including rain, snow, and dusty environments. Such durability is essential for maintaining the performance of early warning systems in all weather conditions.
Flexible Communication Interfaces
The modular system supports multiple communication technologies, including:
- TCP/IP
- radio communication
- GSM/LTE
- TETRA
- RS232 / RS485
- Wi-Fi
- I/O and POCSAG
It also includes Text-to-Speech, enabling automatic voice alerts in different scenarios.
Integration with National Warning Systems (MoWaS)
The siren is MoWaS-ready, allowing integration with Germany’s modular warning system. It supports automatic activation via CAP (Common Alerting Protocol) messages, ensuring fast and coordinated emergency alerts.
Modern Civil Protection with Early Warning Systems
The deployment of Gibon 600 W electronic sirens in SG Mittelweser demonstrates how modern public warning infrastructure enhances safety and preparedness. By combining powerful acoustic performance with advanced digital communication, these sirens provide a reliable solution for emergency alerting and civil protection.
