  • Publication number: 20150068777
    Abstract: A fire suppression system comprising multiple thermally activatable automatic sprinklers attached to multiple non-metallic conduits and wherein the pattern of the sprinklers is an asymmetric pattern. The fire suppression system is suitable for unfinished basements and other rooms having exposed joists. The asymmetric pattern is such that the distance between sprinklers installed in the direction of the joist run is at least one foot longer than the distance between sprinklers installed in the direction perpendicular to the joists. The most preferred non-metallic conduits are chlorinated polyvinyl chloride conduits.

  • Publication number: 20140138105
    Abstract: An aqueous fire sprinkler fluid containing low carbon number carboxylate salts for freezing point depression is described. The salts may be used in conjunction with glycols. The salts decrease the combustibility of the glycol containing fluids and give lower viscosity than higher glycol fluids, both benefitting fire sprinkler systems. These salt solutions are friendly to metal and CPVC pipes and are thus useful for fire sprinkler systems by not causing environmental stress cracking of the CPVC components and not being corrosive to the metal parts.

  • Publication number: 20110139264
    Abstract: A fluid handling system is operative to deliver water based fluid through a plurality of plastic pipes and fittings to a plurality of fire suppression sprinkler heads (12). The fluid handling system includes a plurality of fittings (14, 16, 18, 20, 22). The fittings are joined in the system in cemented relation. The fittings and pipes are comprised of chlorinated polyvinyl chloride (CPVC) that is suitable for fire suppression applications. The failure of an installer to connect one or more fittings in the system in cemented relation is detectable through use of an apparatus (24). The apparatus operates to detect uncemented connections while avoiding pressurizing the system above a limit.
