Carbon monoxide detector and control system and method of operation

1. A method of controlling a device having an on-state and an off-state and capable of producing carbon monoxide in the on state, the control system including a control actuator, a sensor, and a controller in communication with the control actuator and the sensor, said method comprising:

sensing with the sensor a carbon monoxide level proximate to the device;

communicating the carbon monoxide levels from said step of sensing to the controller;

determining with the controller based on communicated carbon monoxide levels if the device is located in an enclosed area or outdoors;

activating the control actuator with the controller to ensure that the device is in the off-state in response to determining that the device is located in an enclosed are during said step of determining.

2. The method of claim 1 further including the steps of:

determining that the carbon monoxide level does not exceed a predetermined threshold; and

determining that the carbon monoxide level does not exceed a predetermined rising average.

3. The method of claim 2 further including the steps of:

determining that the carbon monoxide levels are below a preset low threshold;

deactivating the control actuator to allow the control actuator to enter a run state in response to determining that the carbon monoxide levels are below a preset low threshold; and

clearing any alarm conditions.

4. The method of claim 3 further including repeating the cycle of steps at regular intervals.

5. A method of controlling a device having an on-state and an off-state and capable of producing carbon monoxide in the on state, the control system including a control actuator, a sensor, and a controller in communication with the control actuator and the sensor, said method comprising:

sensing with the sensor a carbon monoxide level proximate to the device;

communicating the carbon monoxide levels from said step of sensing to the controller;

determining with the controller the presence of a rising average of carbon monoxide levels and determining if the device is located in an enclosed space or outside and activating the control actuator with the controller to ensure that the device is in the off-state in response to determining that the device is located in an enclosed space;

comparing the rising average of carbon monoxide levels to a predetermined rising average threshold level, upon determining that a rising average of carbon monoxide levels exists during said determining step;

activating the control actuator with the controller to ensure that the device is in the off-state in response to said step of comparing showing that the rising average of carbon monoxide levels exceeds the predetermined threshold.

6. The method of claim 5 , wherein said step of determining includes the step of determining a rising average over a set period of time.

7. The method of claim 5 wherein said steps of sensing, determining, comparing and activating occur before a user attempts to initiate the on state with the device.

8. The method of claim 7 further including a step of preventing initiation of the on state with the control actuator in response to the rising level of carbon monoxide exceeding the predetermined threshold level in said step of comparing.

9. The method of claim 8 wherein said step of determining also includes determining with the controller if the level of carbon monoxide sensed in said step of sensing exceeds a predetermined level.

10. The method of claim 7 further including a step of changing the on state to the off state with the control actuator in response to determining that the level of carbon monoxide exceeds a rising average, in said step of determining.

11. The method of claim 7 further including a step of preventing initiation of the on state with the control actuator in response to determining that the level of carbon monoxide exceeds a maximum threshold.

12. The method of claim 7 further including a step of changing the on state to the off state with the control actuator in response to determining that the level of carbon monoxide exceeds a maximum threshold.

13. The method of claim 5 wherein said step of sensing includes measuring the current output of the sensor and further including the step of calculating the accumulation levels of carboxyhemoglobin that would be occurring in the human body.

14. The method of claim 5 further including a step of performing a self-diagnostic on at least one of the carbon monoxide sensor, control actuator and battery capacity.

15. The method of claim 5 further including a step of determining the carbon monoxide levels are below a preset low limit while said control actuator is in the off-state in response to said step of activating and further including the step of instructing the control actuator with the controller to be in the on-state.

16. The method of claim 15 further including the step of clearing alarm indicators in response to said step of determining the carbon monoxide levels are below a preset low limit.

17. The method of claim 15 further include a step of multiple cycles of determining the carbon monoxide levels are below a preset low limit before performing said step of instructing the control actuator with the controller to be in the on-state.
