Automatic Smoke/Carbon Monoxide Power Cut-Off Method and System

An automatic smoke/carbon monoxide power cut-off system for a furnace, comprising:

• a microprocessor co-located with the furnace;
• a thermostat having a smoke/carbon monoxide sensor in wireless communication with the microprocessor and configured to detect presence of smoke/carbon monoxide and wirelessly transmit a sensor signal to the microprocessor, and the microprocessor being configured to generate a trigger signal in response to the sensor signal indicative of smoke/carbon monoxide exceeding a predetermine level;
• and
• a power cut-off device coupled to the microprocessor and configured to automatically cut off power to the furnace in response to the trigger signal, so that the furnace automatically stops operation.

An automatic carbon monoxide power cut-off system for a carbon monoxide source, comprising:

• a microprocessor co-located with the carbon monoxide source;
• a carbon monoxide sensor in wireless communication with the microprocessor and configured to detect presence of carbon monoxide and wirelessly transmit a sensor signal to the microprocessor, and the microprocessor being configured to generate a trigger signal in response to the sensor signal indicative of carbon monoxide exceeding a predetermine level;
• and
• a power cut-off device coupled to the microprocessor and configured to automatically cut off power to the carbon monoxide source in response to the trigger signal, so that the carbon monoxide source automatically stops generating carbon monoxide.

A method of operating carbon monoxide generating equipment comprising:

• monitoring carbon monoxide levels in the ambident air;
• generating a trigger signal in response to sensing carbon monoxide levels exceeding a predetermine threshold;
• notifying a user;
• and
• performing one of the following:
• cutting off power to the carbon monoxide generating equipment in response to receiving user command to shut off the equipment;
• changing the predetermined carbon monoxide threshold in response to receiving user command to change the carbon monoxide threshold;
• and
• automatically cutting off power to the carbon monoxide generating equipment in response to an absence of user command after a predetermined time period after notifying the user.
