A. 8500-01 Vulcan RF and 8593-01 Copperhead
RF Monitor
(Figure 6) The 8500-01 Vulcan RF Monitor is a cast
aluminum monitor with a highly efficient waterway, while the
8593-01 Copperhead RF Monitor is brass. The waterway
contains a central vane to minimize large-scale turbulence and
provide superior fire streams. Monitor water supply is
provided through the monitor base by either an 3” 150# flat
faced flange, a 3” NPT (Vulcan RF), or a 4” 150# flat faced
flange. The discharge nozzle connection is a 2½“ National
Hose Thread. Nozzle stream direction is controlled by two
permanent magnet type gear motors, one controlling rotation
about the axis of the water inlet, and the other controlling
nozzle elevation and depression.
The monitor flow capacity is 1250 gallons per minute.
Monitors are normally supplied with the SM-1250E or SM-
1250BE
constant pressure (automatic) type master
stream nozzle. This nozzle has a flow range of 300 to 1250
gallons per minute at 75 psi, and has an electric drive
mechanism for control of the spray pattern from a straight
stream to wide fog. For optimum straight stream
performance, stream shapers are provided as part of the
monitor and nozzle system. Solid stream nozzles are also
available for use with this monitor.

The 8500-01 and 8593-01 models have a unique rotating electrical connection between the inlet
base and the body of the monitor gives the monitor the ability to rotate around the base
continuously without twisting any wires. This eliminates any “dead zone” and allows the
operator to take the shortest route to the target.
A hall effect sensor provides the vertical motion feedback. Magnets provide stop locations at 90º
above and 45º below the horizontal plane.
Monitor Features:

Fully vaned, rugged cast aluminum waterway

1250 GPM flow

Rotating connector for unlimited travel in the horizontal direction
B. 8500-01 EXT Vulcan RF and 8593-01 EXT Copperhead RF Monitor
(Figure 7) The aerial Vulcan and Copperhead has the same highly efficient waterway and flow
capacity as the Vulcan RF monitor. The monitor waterway is supplied through a 4” 150# or 3”
150# flat faced flange base. The 8500-01 EXT and 8593-01 EXT monitors have a mechanical
stop to allow 180

for added protection in an aerial application.
