Abstract: A method and device for suppressing an electrical fire within an electrical wire carrying conduit. The device is a flexible receptacle containing an admixture of super absorbent polymer and water having substantially superior fire suppression and extinguishing properties that does not provide an electrically conductive environment. The receptacle is drawn though a conduit either before or after wires have been placed in the conduit, and the filled with the admixture. A sleeve may be placed over the receptacle to prevent breaching of the receptacle during installation. Once the receptacle and admixture is positioned within the conduit, should arcing or a buildup of heat occur, the receptacle will rupture and the admixture will cover the specific area. These particular properties and ratios of the admixture will enable electrical fires to be extinguished more rapidly and not flare back up. The admixture further encapsulates noxious and toxic gases associated with electrical fires.

Abstract: A valve body has a piston that slides within the body through four successive positions. The piston has a head, and an upper and lower skirt, with a port in the upper skirt. In the first position, a bias force urges the piston to the first of four positions, in which the piston port is closed. In a second position, the piston port aligns with a low pressure port in the valve body, when a low pressure supply of water is connected. In a third position, greater pressure again closes the piston port. In a fourth position, at a still greater pressure, the piston port aligns with a high pressure port in the valve body. The bias force or a location of the piston port can be varied for valves along a supply line, whereby varying supply pressure opens different valves, thereby enabling addressing of valves according to supply pressure.
