Smoke detection for early fire detection in road tunnels

Get Adobe Flash player

Every minute counts in a tunnel fire: Because the concentration of soot particles increases faster than the temperature, optical sensors can detect a fire very early. The VISIC50SF tunnel sensor uses the scattered light method with protected measurement volume. It is able to achieve such high reliability that its alarms are processed automatically.
