ABSTRACT:
A test assembly for water-flow alarms having a housing made up of two sections. One section includes a control valve, and the other section a viewing chamber. The control valve is capable of a passing water therethrough at two distinct flow rates, one of which being equivalent to the flow rate passing through the orifice of a sprinkler. The viewing chamber contains a uniquely designed sight module therein through which the flow of water can be viewed. By incorporating the test assembly within a sprinkler system it is possible to reliably test a water-flow alarm without activating the sprinkler within the system.
