Fire suppression system

摘要

A fire detection system includes a detection tube (22) and a sensing device (16). The detection tube (22) contains a sensing fluid (23) having a first physical condition and a second physical condition. The sensing fluid (23) is in the first physical condition below a temperature threshold, and is in the second physical condition above the temperature threshold. The sensing fluid (23) is at least partially liquid in the first physical condition. The sensing device (16) 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.
