7. Select the pipe connector, and change its system classification from
Fitting to Fire Protection Wet and change the flow direction to Out.
Map the flow to the Gallons per Minute parameter you created.
8. Delete any undesired existing linework.
Flow Direction
In our POC family, the pipe connector flow direction is set to Out
because water flows
out
of the water meter/POC and
in
to the pipe.
Conversely, water flows
out
of the pipe and
in
to each fire sprinkler, so
the flow direction for the pipe connector in a sprinkler family should be
set to In.
Fire Pump Assembly
You should try to preassemble as many of the fire-protection components
as possible to help reduce production time.
Figure 16.2
shows a fire pump
preassembled so that you would have to change out only certain
components—for example, changing the pump for a smaller or larger pump,
depending on what is called for by the calculated fire flow demand.
