PROBLEM TO BE SOLVED: To detect an imperfect combustion of a plurality of combustion machineries with a single carbon monoxide detecting device. SOLUTION: The voltage between the electrodes 12, 13 of carbon monoxide sensor element part 17 reflecting the information on carbon monoxide concentration is amplified by an amplifier 18. The output of the amplifier 18 is compared with a prescribed voltage value determined by a voltage comparison means 20 in a voltage comparator 19, and, if it is greater, the command of combustion stop is given to a plurality of combustion meachineries by a combustion stop command means 21. Thereby, the danger of carbon monoxide poisoning can be prevented. |
