A. 8294-04 Scorpion Monitor
(Figure 2) The 8294-04 Scorpion is a cast aluminum
monitor with 4" waterway. The waterway contains a
central vane to minimize large-scale turbulence and
provide superior fire streams. Monitor water supply
connection is a 4 inch 150 lb. ANSI pattern flange. The
discharge nozzle connection is 3-1/2 inch National Hose
thread. Nozzle stream direction is controlled by two
permanent magnet type planetary gear motors, one
controlling rotation about the axis of the water inlet, and
the other controlling nozzle elevation and depression.
Right angle gear cases between the gear motor and the
monitor allow for convenient manual override of the
electric motors in the event of a power failure during
firefighting operations. All gearing is enclosed within the
monitor housings.

8294-04 Monitor with SM-2000E Nozzle
The maximum monitor flow capacity is 2000 gallons per minute. Monitors are normally
supplied with the SM-1250E
constant pressure (automatic) type master stream
nozzle. This nozzle has a flow range of 300 to 1250gpm@80psi, and has an electric drive
mechanism for remote control of the spray pattern from a straight stream to wide fog. Other
nozzles that my be used on this monitor are:
¾ SM-1000E
300 to 1000gpm@80psi
¾ SM-1500E
500 to 1500gpm@75psi
¾ SM-2000E
500 to 2000gpm@80psi.
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
