Abstract
A cartridge with a status indicator, a fire suppression system for incorporating the same, and a method of inspecting whether a fire suppression system is capable of being actuated are provided. The status indicator is connected to the body of the cartridge. The status indicator defines a first state and a second state. The status indicator undergoes a change from the first state to the second state when exposed to a physical change. The physical change may include at least one of a decrease in temperature beyond a threshold, an increase in relative humidity beyond a threshold, and a threshold differential temperature change. The physical change is caused by the discharge of the cartridge. When installed within a fire suppression system, the status indicator enables the visual inspection of whether the fire suppression system is capable of being actuated.
