A flow control assembly for a fire sprinkler system includes a valve housing having an inlet opening and an outlet opening. The valve housing defines a fluid flow path that extends between the inlet opening and the outlet opening. A flow control valve is disposed within the fluid flow path. A swing check valve is disposed within the fluid flow path of the valve housing downstream from the flow control valve. The swing check valve includes a clapper that is connected to an actuator arm. An electrical switch is disposed outside of the valve housing. A mechanical linkage includes a first end that extends through the valve housing and engages with the actuator arm. The mechanical linkage also includes a second end that is coupled to the electrical switch. The first end translates with said actuator arm.
