Patent ID: 8122968

Claim:
Apparatus comprising: a fire suppression arrangement, wherein the arrangement includes at least one fire detector, wherein the at least one fire detector is operative to detect at least one condition corresponding to a fire, wherein the arrangement includes a sprinkler line having an inlet, wherein the sprinkler line includes at least one conduit comprising a thermoplastic composition, fire suppression fluid in the at least one conduit, fire suppression fluid source, at least one thermally-activated sprinkler, at least one flow control valve, and a predetermined fluid outlet disposed separately from all of the at least one sprinkler wherein said at least one sprinkler has an outlet, wherein the at least one flow control valve is in operative connection with the at least one fire detector, wherein the at least one flow control valve is closed when the at least one condition is not detected, and wherein the at least one flow control valve is operative to open responsive to detection of the at least one condition by the at least one fire detector, wherein said fire detector is operative to cause an electrical signal to be generated, wherein said electrical signal from said fire detector is received by said flow control valve and said electrical signal causes said flow control valve to change from its normally closed condition to an open condition, wherein the at least one open flow control valve also causes fluid flow from the source into the sprinkler line through the inlet, wherein opening of the at least one flow control valve causes fluid to flow through the sprinkler line and through said separately disposed outlet, prior to activation of said thermally-activated sprinkler: and wherein the at least one fire detector is positioned relative to the at least one sprinkler, such that the at least one fire detector is operative to detect the at least one condition prior to activation of any of the at least one sprinkler.
