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.

1. A flow control assembly for a fire sprinkler system, comprising: a. a valve housing including a single valve body, said valve body defining, an inlet opening an outlet opening and a fluid flow path between said inlet opening and said outlet opening;b. a flow control valve disposed within said fluid flow path downstream, of said inlet opening and upstream front said outlet opening, wherein said flow control valve is mounted to said valve body;c. a swing check valve disposed within said fluid flow path of said valve body downstream from said flow control valve and upstream from said outlet opening, said swing check valve having a clapper connected to an actuator arm, wherein said clapper swings automatically into an open position in response to a pressure drop downstream from said outlet opening;d. an electrical switch mounted to an outside surface of said valve body; ande. a mechanical linkage having a first end that extends through a pivoting seal assembly and into said valve body and engages with said actuator arm of said swing check valve and a second end coupled to said electrical switch, wherein said first end translates with said actuator arm and said second end automatically actuates said electrical switch in response to a pressure change between the inlet opening and the outlet opening, wherein said electrical switch provides an alarm signal to indicate water flow through said fluid flow path based on movement of said swing check valve. 2. The flow control assembly as in claim 1, wherein said electrical switch provides an alarm signal to indicate water flow through said fluid flow path based on movement of said swing check valve. 3. The flow control assembly as in claim 2, further comprising an alarm signal delay device electronically connected to said electrical switch, wherein said alarm signal delay device delays or prevents transmission of said alarm signal. 4. The flow control assembly as in claim 1, wherein said valve housing includes a fluid plenum that is in fluid communication with said fluid flow path, said actuator arm extending within said fluid plenum. 5. The flow control assembly as in claim 4, wherein a first end of said mechanical linkage extends through said valve body into said fluid plenum. 6. The flow control assembly as in claim 1, wherein said valve body at least partially defines a test and drain outlet opening disposed downstream from said swing check valve and upstream from said outlet opening. 7. The flow control assembly as in claim 1, further comprising a pressure gage that extends through said valve body to provide a pressure measurement within said fluid flow path. 8. The flow control assembly as in claim 1, further comprising a relief valve that extends through said valve body, wherein said relief valve is in fluid communication with said fluid flow path. 9. The flow control assembly as in claim 1, further comprising a valve position indicator disposed outside of said fluid flow path, wherein said valve position indicator is mechanically linked to said flow control valve. 10. The flow control assembly as in claim 1, wherein the valve housing includes a first side portion and an opposing second side portion, the flow control assembly further comprising a handle mechanically linked to said flow control valve, wherein said flow control handle is reversible between said first and second sides. 11. The flow control assembly as in claim 1, wherein said flow control valve includes a valve stem that extends through said valve body, and said flow control valve includes a displacement switch mechanically coupled to said valve stem. 12. A fire sprinkler supply system, comprising: a. a standpipe riser;b. a fire sprinkler head disposed downstream from said standpipe riser; andc. a flow control assembly that provides for fluid communication between said standpipe riser and said fire sprinkler head, wherein said flow control assembly comprises:i. a valve housing comprising a single: valve body, said valve body defining an inlet opening in fluid communication with said standpipe riser and an outlet opening in fluid communication with said fire sprinkler head, wherein said valve body defines a fluid flow path between sai inlet opening and said outlet opening;ii. a flow control valve disposed within said fluid flow path of said valve body downstream of said inlet opening and upstream from said outlet opening, wherein said flow control valve is mounted to said valve body;iii. a swing check valve disposed within said fluid flow path of said valve body downstream from said flow control valve and upstream from said outlet opening, said swing check valve having a clapper connected to an actuator arm, wherein said clapper swings into an open position in response to a pressure drop downstream from said outlet opening;iv. an electrical switch mounted to an outside surface of said valve housing; andv. a mechanical linkage having a first end that extends through a pivoting seal assembly and into said valve body and that engages with said actuator arm of said swing check valve, said mechanical linkage having a second end coupled to said electrical switch, wherein said first end of the mechanical linkage translates with said actuator arm and said second end automatically actuates said electrical switch, in response to a pressure change between the inlet opening and the outlet opening, wherein said electrical switch provides an alarm signal to indicate water flow through said fluid flow path based on movement of said swing check valve. 13. The fire sprinkler supply system as in claim 12, wherein said electrical switch provides an alarm signal to indicate water flow through said fluid flow path based on movement of said swing check valve. 14. The fire sprinkler supply system as in claim 13, wherein said flow control assembly further comprises an alarm signal delay device electronically connected to said electrical switch, wherein said alarm signal delay device delays or prevents transmission of said alarm signal. 15. The fire sprinkler supply system as in claim 12, wherein said valve body defines a fluid plenum that is in fluid communication with said fluid flow path, said actuator arm being disposed within said fluid plenum. 16. The fire sprinkler supply system as in claim 15, wherein a portion of said mechanical linkage extends through said valve body into said fluid plenum. 17. The fire sprinkler supply system as in claim 12, further comprising a drain pipe, said valve body including a test and drain outlet opening disposed downstream from said swing check valve and upstream from said outlet opening, wherein said test and drain outlet opening provides for fluid communication between said fluid flow path and said drain pipe. 18. The fire sprinkler supply system as in claim 12, wherein said flow control assembly further comprises a pressure gage that extends through said valve body to provide a pressure measurement within said fluid flow path. 19. The fire sprinkler supply system as in claim 12, wherein said flow control assembly further comprises a relief valve that extends through said valve body, wherein said relief valve is in fluid communication with said fluid flow path. 20.
