TunnelTech 102

Cold Smoke Monitor

The TunnelTech 102 Cold Smoke Monitor is an essential part of any road or rail tunnel safety system. The CODEL CSM detects smoke from a fire to rapidly warn the operator of the hazard.

Secondly, used in combination with other TunnelTcch 101 VIS monitors, the operator can quickly detect the focus of the fire if it is also equipped with the optional PT 101 temperature sensor to accurately measure ambient air temperature in a range of -15 to 105°C.
