Smoke detection for early fire detection in railroad tunnels

Fire in a railway tunnel can have catastrophic consequences – that's why every minute counts. The VISIC50SF tunnel sensor detects fire very quickly and reliably based on the particle concentration in the tunnel air. Compared to temperature measurements, the advantage of this method is a fast response time and almost complete prevention of false alarms.
