Abstract: A fire extinguishing agent concentration measuring system having a first window, a second window positioned relative to the first window thereby defining a sensing volume between the first window and the second window, and a structure positioned relative to the first window and the second window configured to cause fluid flowing into the sensing volume from an environment within which the fire extinguishing agent concentration measuring system is placed to swirl within the sensing volume.

Abstract: A fire extinguishing agent concentration measuring system including a first window, a second window positioned relative to the first window thereby defining a sensing volume between the first window and the second window, a tube configured to port a flow including the agent from an environment through the sensing volume, and a fluid motion mechanism in operable communication with the tube configured to cause the flow through the tube and through the sensing volume.

Abstract: A test kit includes a tube arranged to channel smoke generated by a smoke generator, a mount arranged to support the tube relative to the smoke generator in a predetermined orientation and a predetermined spacing relative to the smoke generator, and a sensor. The sensor is arranged for coupling to the tube and generating data indicative of one or more property of the smoked generated by the smoke generator and channeled by the tube to monitor performance of the smoke generator. Test arrangements, test systems, and methods of monitoring smoke generators are also described.

Abstract: A fire extinguisher includes a source conduit, a flow control device connected to the source conduit, and a supply conduit. The supply conduit is connected to the flow control device, is fluidly coupled therethrough to the source conduit, and is thermally coupled to the source conduit to communicate heat between pressurized fire suppression agent entering the flow control device through the source conduit and expanded fire suppression agent issuing from the flow control device through the supply conduit. Fire suppression systems and methods of controlling flow of fire suppressant agents are also described.

Abstract: A fire extinguisher includes a main dome surrounding an interior. An internal plate is mounted inside the interior of the main dome, dividing the interior into an internal space housing agent and a secondary internal space. The internal space housing agent and the secondary internal space are both pressurized above ambient. The secondary internal space is free of agent, and can be pressurized, e.g., to no less than the total pressure of the internal space housing agent.
