Abstract

Systems and methods for the remote testing of a paddle-type flow detector, such as are common in fire protection systems. Specifically, the systems and methods provide for mechanical movement of the vane to test activation of the flow detector under a flow condition, and which measure the amount of time the vane takes to return to the ready position to verify the presence of a paddle on the vane.
