Your Benefits

  • Early and reliable warning for optimum efficiency during self-rescue phase

Overview

Fast and reliable smoke detection for every type of tunnel

Fast and reliable detection of smoke in tunnels delivers information which helps to save human lives and avoid material damage. The SMOTEC450 detects smoke particles in tunnels within seconds and alerts the control system immediately – long before visibility is reduced too much by dense smoke. False alarms caused by fog are avoided by heating up the drawn air.

Double safety, because the device monitors itself. The automatic check cycle of the SMOTEC450 checks all important components of the system each day without the tunnel having to be closed and without incurring personnel costs.
