A gas-detecting apparatus, having a gas inlet and a gas outlet, for detecting a false alarm is disclosed. The gas-detecting apparatus comprises a control module, a sensor module, and an air chamber. In an example embodiment, the sensor module is electrically connected with the control module. The sensor module has a sensor inlet and a sensor outlet. The sensor inlet is fluidly coupled to the gas inlet of the gas-detecting apparatus. The air chamber has an air inlet and an air outlet, wherein the air inlet is fluidly coupled to the gas inlet of the gas-detecting apparatus and the air outlet is fluidly coupled to the gas outlet. The control module is configured to receive a first sensing signal for a first level of gas from the sensor module and determine whether magnitude of the first sensing signal is higher than a first threshold value. In an instance when the magnitude of the first sensing signal is higher than the first threshold value, the control module causes the air chamber to supply ambient air to the sensor module through the sensor inlet of the sensor module.
