Advances in rate of rise detection and linear heat detection could possibly detect a heat source before CO is created providing an earlier warning of a possible trouble condition. Some new products can provide continuous detection for 11000 feet while being broken into 128 separate zones giving the capability of locating the heat source within 86 feet. It is my opinion that these shuold not replace CO detectors, but also should not be discontinued.
