The Fireboy-Xintex CMD5-MD Carbon Monoxide Alarm warns boaters of dangerous levels of this toxic gas. Once wired into your boat's 12v or 24v system the CMD5-MD detector uses ultra low current to power the sensor. The microprocessor sensor in CMD5-MB uses a "Time Weighted Average" (TWA) process to monitor CO concentration, temperature and time to calculate levels of Carboxyhemoglobin (COHb). COHb is the degree to which the oxygen carrying capacity of the blood is impeded by the union of carbon monoxide to the hemoglobin and is expressed as a percentage. The human body absorbs CO easier than oxygen and COHb is the ratio of absorbed carbon monoxide to oxygen in the bloodstream. The CMD5-M alarm calculates this COHb as a function of time and determines the appropriate alarm response.
