PURPOSE:To contrive to alarm the danger due to an incomplete burning in a living space by a method wherein a processing part is provided to output a signal when an oxygen concentration becomes lower than the designated value, an alarm part is provided to alarm according to the signal, and an alarm transmitting part is provided. CONSTITUTION:A detecting part 1 measures continuously an oxygen concentration in a high airtight living space where an opening type burning apparatus is used, the results are transmitted to a processing part 2. The processing part compares a concentration information from the detecting part 1 with the preset alarm concentration and 18% concentration. When the concentration becomes lower than the alarm concentration, the processing part 2 sends a signal to an alarm driving part 3. The alarm driving part 3 operates a buzzer 4 and a lamp 5, notifies the danger occuring of CO2 gas generation due to the decreasing of the oxygen concentration to the people in the living space. At the further decreasing of the oxygen concentration down to the 18% concentration which is the tolerance limits for the human body, the processing part 2 outputs a signal to an alarm transmitting part 6, then the alarm transmitting part 6 transmits an alarm to an alarm monitoring center through a signal line 7. |
