Operation of Fireboy-Xintex Carbon Monoxide Alarm(s)
Should a very high level of carbon monoxide exist, the CO Alarm will alarm in a few minutes.
However, if small quantities of CO are present or high levels are short-lived, the micro controller
will accumulate the information and determine when an alarm level has been reached. This
feature eliminates nuisance alarms. For example, in a boat it is possible to see high levels of CO
for a very short time such as when docking or maneuvering. The CO Alarm takes this all under
consideration by totaling the quantity of CO detected over a period of time.
The CO Alarm is programmed to alarm at a COHb level of 10%. Alarm points are 70 ppm (60-240
minutes), 150 ppm (10-50 minutes), and 400 ppm (4-15 minutes). Alarm will clear when the CO
level drops below 40 ppm.
