The monitor will analyze the air sample and display the CO concentration in parts per million (ppm). The system’s green
“NORMAL” operation light will illuminate and the red “HIGH CO” light will fl icker approximately every second when the CO
level is below 10ppm (5ppm Canadian). If the CO concentration level exceeds the alarm set point, the green “NORMAL”
light will turn off, the red “HIGH CO” light will illuminate, the audible alarm will sound, and the remote alarm connections
will energize. Once the CO concentration levels drop below the alarm set point, all alarm indicators will deactivate and the
unit will return to “NORMAL” operation.
