The wireless fire alarm carried by the WISE units was born from the A86 tunnel fire in 2002.

Communication network

  • IP communication system

    Supports high-quality video calls, radio, and wireless phone communication

  • Public address integration

    Broadcasts instructions or routine messages during emergencies

  • Dual connectivity networks

    Provides secure local and internet-enabled Wi-Fi access

  • Dedicated IP local network

    Secure and private network that keeps communications running smoothly and safely

  • Real-time I/O monitoring

    Interfaces with analog input/output systems

On the Femern Link, more than 600 devices form the Femern Link network across the tunnel and the casting facility.

Counting and localisation

  • Accurate positioning

    Tracks individuals and assets by area in real-time

  • Zone-based monitoring

    Live headcounts and zone-level access visibility

  • Smart alerts

    Notifications based on time of presence or restricted area entry

  • Data logging and analytics

    Records of movement data and reports

  • Instant tag search

    Locates any tagged person or object within seconds

In the Alps, the system keeps 1,600 workers tracked daily on Lyon-Turin.

Data integration

  • Cross-system connectivity

    Links fire safety, lighting, gates, and other systems into one coordinated platform

  • Automation across functions

    Trigger smart actions (e.g. unlock gates during evacuation, activate lights in emergency zones) in real time

  • Centralised oversight

    Monitors and manages diverse subsystems through a single, unified interface

  • Open interfaces

    REST API and MQTT available in the solution to exchange data with the client's systems: BMS, supervision, SCADA and business tools
