PURPOSE: A suction type reliability test equipment of gas leakage alarm device is provided to automatically test quantity of gas and a leakage of gas and increase reliability of test. CONSTITUTION: The suction type reliability test equipment of gas leakage alarm device comprises a mode switch, a first electronic valve, a forth electronic valve, an air pump, a manometer, an optical sensor, a timer, and a controller. In the suction type reliability test equipment of gas leakage alarm device, the mode switch selects a pump suction test more or an airtight test mode. The first electronic valve and the forth electronic valve are opened by the mode switch. The air pump is drove by the mode switch. The manometer measures air pressure through the air pump. The optical sensor detects a height of manometer. The timer is drives by a output signal of the optical sensor. The controller displays a quantity of suction for the pump and a quantity of leakage for the air.
