COFEM - Model BCO -NO2 Detector for parkings
FromCOFEM SA
Dioxide Nitrogen (NO2) diffusion sensor for COsensor system designed according to the European standard EN 50545-1 and UNE 23300 certified.
The sensor is designed to work with all models of COsensor control panels, both conventional (CCO and MiniCO models) and addressable (ZafirCO). .
It is allowed installation of CO and NO2 sensors in the same detection zone line. Relation between NO2 and CO is lineal indicating 100 ppm of CO with 2,5 ppm of NO2. Connected with addressable control panel, it makes double flash when the concentration read by the sensor is equal or higher than the ventilation level programmed at control panel, and fixed light when concentration read by the sensor is equal or higher than the alarm level programmed at control panel.
NO2 sensors must be distributed at the installation in accordance with standards and/or regulation. A recommendable coverage for these devices are between 200 and 300 m2, and place in a height between 1,5 and 2 m from the floor.
