PURPOSE: An alarm bouncing elimination method is provided to eliminate an alarm bouncing in an alarm sensing system based on a maintenance time of an alarm generation state. CONSTITUTION: The method comprises steps of detecting a value of a malfunction generation register by a set period(210), increasing a counter value(212), detecting if the value of the malfunction generation register is abnormal or varied(214), initializing the counter value in the case that the value of the malfunction generation register is normal or not varied(216), detecting if the counter value is over a critical value in the case that value of the malfunction generation register is abnormal or varied(218), returning to the step 210 in the case that the counter value is not over a critical value, and determining a malfunction generation and performing a corresponding operation in the case that the counter value is over a critical value(220).
