A gas detection method and system for detecting a predetermined gas in a system is disclosed. A gas detection system includes a valve system for initially positioning a first gas sensor in fluid communication with a first sensing location and a second gas sensor in fluid communication with a second sensing location. In response to detecting the predetermined gas with a selected sensor from a selected sensing location, the other sensor that did not detect the predetermined gas is placed in fluid communication with the selected sensing location for which the selected sensor sensed the predetermined gas. If the other sensor also detects the predetermined gas in the selected sensing location, an alarm occurs. If the other sensor does not detect the predetermined gas in the selected sensing location, the selected sensor is recalibrated.
