The carbon monoxide detector should be installed in a location where wind monoxide may be generated, but at least 1.5 to 3 meters from a potential carbon monoxide source. The sensor must be placed at least 15 cm above the upper line of the windows and doors, but below the ceiling. When mounting on the ceiling, keep a distance of at least 30 cm from the partitions. It is advisable to install 2 sensors for greater operational safety. If the sensor is placed in a room where there is no direct source of carbon monoxide, it is advisable to place the sensor at a breathing height. In the bedroom, for example, the bed line. If the ceiling is not horizontal, attach the sensor to the higher ceiling section.
