Abstract: The present invention concerns a portable building fire suppression system which allows fire-fighters to position the device within a building early on in the firefighting process. The device may use automated controls to begin fire suppression. Further, a number of electronics including lighting, smoke detection, alarms, camera, motion sensor, and the like may be included on the portion of the device inserted into the building. These electronic systems may provide vital information early in the firefighting process to inform fire fighters about conditions within the building.

Abstract: An improved suction nozzle is comprised of a narrow constant height slot passageway open at one end and communicating at the other end with an expansion chamber which, in turn, is connected to a cylindrical manifold. An orifice in the end of the manifold assists in the development of parallel fluid flow along the manifold axis.
