SYSTEM COMPONENTS
MONITOR
Monitor – 7400
The monitor is specially designed for severe
duty cycles. Unique waterway swivel joints utilize stainless steel
thrust rods and needle roller thrust bearings for unprecedented
durability in all firefighting applications. The monitor can be
controlled by hardwired input devices via CAN bus or by an optional
upgraded Radio Frequency (RF) device. The monitor may be
powered with 12 or 24 Volts.
High power, permanent magnet variable speed DC gear motors that
drive the left-right and up-down monitor motions are NEMA 4 rated
for use in harsh environments. The monitor
has a flow efficient 3½” vaned waterway to minimize turbulence and
provide superior nozzle streams. The water supply connection in the
monitor base is a 4”-150# flange, and the discharge nozzle
connection has a 3½” national hose male thread.
An optional 4” electric valve kit is available to allow the user to control water flow directly from the EXM
input device. This enables “pump and roll” functionality with complete control by the operator in the
cab.
Caution:
All EXM monitor motors are 12VDC. If using a non-EXM nozzle, another
12VDC nozzle should be used, or nozzle control may not function properly.
NOZZLE
Nozzles –
There are two nozzles available for the .
SM-1250E & SM-2000E
Each nozzle automatically adjusts to maintain effective stream
and maximum reach at variable flows. These nozzles have
been calibrated to work at lower pressures, from 75 to 80
PSI, to better suit real world conditions.
SM-1250E; 350 GPM @ 50 PSI - 1250 GPM @ 75 PSI
SM-2000E; 500 GPM @ 50 PSI - 2000 GPM @ 80 PSI
