1. An arrangement for remotely testing a fire suppression sprinkler system, comprising:
- conduit means for supplying a fire suppression fluid to a plurality of sprinklers;
means for sensing a flow of said fire suppression fluid in said conduit means;
means for providing a flow through a passageway corresponding to the flow of said fire suppression fluid through one of said sprinklers;
remotely controlled valve means for selectively opening and closing said passageway, whereby said fire suppression sprinkler system may be remotely tested, said remotely controlled valve means having an inlet and an outlet;
second valve means for selectively opening or closing a second passageway, said second valve means having an inlet and an outlet, at least one of said inlet and said outlet of said second valve means always being in communication with said inlet or said outlet of said remotely controlled valve means.

6. A valve arrangement for use in a fire suppression sprinkler system, said valve arrangement comprising:
-
first valve means for controlling the flow of a fluid, said first valve means comprising an inlet and first and second outlets, said first valve means comprising a first configuration selectively preventing flow from the inlet to the first outlet and a second configuration selectively permitting flow from the inlet to the first outlet at a preselected rate corresponding to the flow through a single fire suppression sprinkler, said first valve means also permitting flow from the inlet to the second outlet when said valve means is in said first configuration;
second valve means for controlling the flow of a fluid, said second valve means comprising an inlet and an outlet, said inlet of said second valve means being in communication with the second outlet of said first valve means, said second valve means comprising a first configuration selectively preventing flow from the inlet to the outlet of the second valve means and a second configuration selectively permitting flow from the inlet to the outlet of the second valve means;
means for restricting the flow through the second valve means to a preselected rate corresponding to the flow through a single fire suppression sprinkler. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A valve arrangement for remotely testing a fire suppression sprinkler system, said valve arrangement comprising:
-
conduit means for supplying a fire suppression fluid to a plurality of sprinklers;
means for sensing a flow of said fire suppression fluid in said conduit means;
supply valve means for controlling a flow of fluid through said conduit means;
first testing valve means for testing the means for sensing a flow of said fire suppression fluid in said conduit means, said first testing valve means comprising an inlet and an outlet, said first testing valve means comprising a first configuration selectively preventing flow from the inlet to the outlet and a second configuration selectively permitting flow from the inlet to the outlet at a preselected rate corresponding to the flow through a single fire suppression sprinkler;
second testing valve means for testing the means for sensing a flow of said fire suppression fluid in said conduit means, said second testing valve means comprising an inlet and an outlet, said inlet of said second valve means being in communication with the conduit means downstream of the supply valve means; and
,means for restricting the flow through the second testing valve means to a preselected rate corresponding to the flow through a single fire suppression sprinkler. - View Dependent Claims (22, 23, 24, 25, 26, 27)
