<p>PURPOSE:To eliminate the delay of alarm generation at the time of a rapid gas ejection by enhancing discrimination accuracy. CONSTITUTION:A gas detecting part having a gas detecting element 10, a discriminating part 19, an alarm generating part 20 and, besides, an infrared ray detecting element 21 for detecting an infrared ray given from a human being are provided. A gas leakage alarming equipment is constituted in such a manner that the discriminating part 19 makes the alarm generating part 20 execute an operation when the output of the infrared ray detecting element 21 is equal to below the specified output and also the output from the gas detecting part becomes more than the specified output with slow transition, makes the alarm generating part 20 execute the operation when the output of the infrared ray detecting element 21 is equal to below the specified output and also the output from the gas detecting part becomes more than the specified output with steep transition and restrains alarm generation when the output of the infrared ray detecting element 21 is more than the specified output and also the output from the gas detecting part becomes more than the specified output with steep transition.</p> |
