Answer: A fire department connection is a part
of the sprinkler system that the fire department can connect their hoses to
if they need to pump additional water into the sprinkler system. A typical
scenario, is to see the FDC located in the parking lot island near the post
indicator valve. The F.D.C. has 2 brass threaded connections with red caps.
Another scenario is to see it on the wall of the building outside the fire
sprinkler riser room. Both circumstances are dependent on the fire
department requirements. Many fire departments to not want to have the
connection on the wall of a burning building. Walls collapsing and falling
debris have injured thousands of fire fighters while they were trying to
connect fire hoses to the F.D.C. on the wall of the building. It is safer
for the fire department to have the F.D.C. in the parking lot island.
