Abstract
A system that includes, a carbon monoxide detector and first and second connectors, the carbon monoxide detector connected across the first and second conductors, the first and second conductors having a voltage imposed on the conductors that supply power to the carbon monoxide detector, the carbon monoxide detector signals detected carbon monoxide by clamping the first and second conductors to a first voltage less than the imposed voltage; and the carbon monoxide detector signaling a fault within the carbon monoxide detector by clamping the first and second conductors to a second voltage less than the imposed voltage where the second voltage is different than the second voltage and also different than the first voltage.
