20100201531 | CARBON MONOXIDE DETECTOR - A carbon monoxide detection apparatus having one or more carbon monoxide sensors operatively connected to an appliance. The one or more carbon monoxide sensors can detect a threshold level of carbon monoxide and cause the detection apparatus to activate the appliance cutoff switch. Alternatively, the connection to the appliance may be for the measurement of carbon monoxide in a substantially continuously flowing airstream; and/or for measuring in two air locations, one an airstream and the other ambient. An audible alarm may be included for sounding an audible alarm. A separate device may be included which may be activated or deactivated. | 08-12-2010 |
