Elkhart Brass Scorpion RF 8394-07 - Manual (Page 6)

6
If the proximity sensor changes state while the monitor is in the “master stream” position and the
monitor discharge is in the 0° to 30° “up” range, the monitor controller will automatically lower the
discharge to 0° to prevent possible interference with the ladder, or impingement of stream upon
personnel.
Caution:
All monitor motors are 12VDC. If using a non-Elkhart nozzle, another 12VDC
nozzle should be used, or nozzle control may not function properly.
NOZZLE
Scorpion RF Nozzles –
There are two nozzles available for the Scorpion RF.
SM-1250E & SM-2000E
The maximum monitor flow capacity is 2000 gallons per
minute. Monitors can be supplied with the SM-1250E (SM-
1250BE for model 8394-07) 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 RF control of the spray pattern from a
straight stream to wide fog.
A similar nozzle, the SM-2000E (SM-2000BE for 8394-07), provides a flow range of 500 to 2000
gallons per minute at 80 psi. 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 these
monitors.
SM-1250E; 350 GPM @ 50 PSI – 1250 GPM @ 75 PSI
SM-2000E; 500 GPM @ 50 PSI – 2000 GPM @ 80 PSI
CONTROL
Handheld RF Controller
– 81282001
A sealed handheld RF transmitter contains all the controls necessary for
operation of the monitor. The handheld remote allows the operator to
direct the monitor from a significantly improved point of view. With the
wireless remote, the operator can view the stream from the side and
confirm that the stream is hitting its target. Separate push button
switches are provided for up, down, left, right, fog, and stream
functions. The handheld remote has user selectable frequency and
security codes that allow multiple monitors to operate on the same fire
ground at the same time. The remote has an automatic power down
feature that will shut down the power after 5 minutes of no activity. As
an additional power saving feature the radio signal is only transmitted
while a button is pushed. The handheld remote case has a NEMA 4
rating.
