Abstract
A fire detection system includes a detection tube and a sensing device. The detection tube contains a sensing fluid having a first physical condition and a second physical condition. The sensing fluid is in the first physical condition below a temperature threshold, and is in the second physical condition above the temperature threshold. The sensing fluid is at least partially liquid in the first physical condition. The sensing device is movable to open in response to a transition of a portion of the sensing fluid from the first physical condition to the second physical condition.
