The Fireboy-Xintex CMD6-M CO is a safety necessity for boats with enclosed cabins. This alarm uses a sensor operating with a microprocessor to measure Carbon Monoxide (CO) levels. Using a “Time Weighted Average” (TWA) process, it monitors 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 CMD6-M alarm calculates this COHb as a function of time and determines the appropriate alarm response.

You can link up to six CMD6-M detectors in multiple locations on your boat. This advanced CO alarm will alert boat inhabitants of the presence of CO. Drawing the lowest current of any Fireboy-Xintex CO detectors, the CMD6-M operates on either 12 or 24 VDC. An advanced design leaves the sensor unaffected by common cleaning solvents so you can keep your boat and CO alarm in tip-top shape. You can equip the CMD6-M with an optional RCM-5 relay (sold separately) so that when dangerous carbon monoxide levels are detected, it will shut down your boat’s generator.
