This new CO detec tor by Xintex combines the CO Sentinel Carbon Monoxide Detector with generator shutdown protection and multiple location warning taking CO detection and safety to the next level. Not only does the CO Sentinel Carbon Monoxide Detector warn you when dangerous CO fumes are detected it also causes all other connected Sentinel CO detectors to sound alarms and shuts down your connected generators. The CO Sentinel uss a microprocessor to measure accumalted Co levels. The computerized alarm uses a time-weighted average that doesn't react prematurely to brief and concetrated, yet harmless whiffs of CO, but knows to alert you in time of the cumulative effect of low concentrations. The circuit is coated on both sides for added protection in the harsh marin enviorment.
