ALARM DEVICE, ALARM SYSTEM AND COMBUSTIBLE LIQUID CONTAINING DETECTION GAS

摘要

PROBLEM TO BE SOLVED: To provide an alarm device capable of setting off an alarm, even before a fire breaks out.SOLUTION: A gas containing a detection gas which is detectable by at least either a sense of smell or a gas detection sensor is mixed with a liquid becoming nanosized bubbles. When the sensor is placed near a combustible material, the liquid can diffuse the detection gas, when the temperature of the combustible material rises up to a level of prior to ignition.
