According to fire tests conformant to EN 54the CO 2 cloud from open fire can usually be detected before particulate. The New York Times. Due to the varying levels of detection capabilities between detector types, manufacturers have designed multi-criteria devices which cross-reference the separate signals to both rule out false alarms and improve response times to real fires. The origin of the North Berkshire fire was determined to be the kitchen, and Fire Marshal Steve Walton says investigators believe it may have started at the stove.
