Detectors 203
Detectors 203 : Particle Detectors: (4.26) Smoke Detector: (2) Design: (2. 4) Carbon Monoxide and Carbon Dioxide Detection: Some smoke alarms use a carbon dioxide sensor or carbon monoxide sensor to detect extremely dangerous products of combustion. However, gas sensors able to warn of poisonous levels of those gases in the absence of a fire have sensitivities based on the uptake of carbon monoxide by haemoglobin, and are not generally sensitive or fast enough to be used as fire detectors
