A fire-control riser system that provides a multi-function unitary valve
system including providing pressure test, pressure relief, and drain/test
fluid flow capability for fire-control sprinkler systems. Furthermore,
the fire-control riser system comprises an enclosure that provides for
easier installation, pre-assembled components and protects such riser
systems from damage during the construction process. Additionally, the
fire-control riser system may be substantially comprised of plastic
material. The system utilizes an improved flow switch coupling-attachment
system that includes no-thread attachment or threaded attachment. The
system also provides for multi-function components as well as reduced
ports for component installation thereby reducing potential leak areas.
