A. Monitor
The Monitor is specially designed to mount on the front bumper of off-road or wildland
fire fighting apparatus. It rotates either 180
° or 334° to spray straight ahead or to either side for use in
fighting forest, grass, range, brush and similar fires. In addition, because is controlled
from inside the cab, risk to firefighters is significantly reduced.
The
features durable Elk-O-Lite
®
construction combined with rugged, stainless steel
gears and motors that are completely enclosed and sealed for maximum protection from the elements.
The
has a flow efficient 2.0” vaned waterway to minimize turbulence and provide
superior fire streams. Water supply is provided through the monitor base by 2” National Pipe Thread
connection. The discharge nozzle connection is a 1½” 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.
An optional 2.0” electric valve kit is available to allow the user to control water flow directly from the
control box. This enables “pump and roll” functionality with complete control by the
operator in the cab of the truck.
B. 81713000 Control Module
The control module is completely encapsulated in
epoxy for maximum protection from the elements.
The module has reverse polarity protection to
prevent damage to the electronic components. The
module uses feedback from Hall effect sensors to
determine when the monitor travel limits have
been reached. It also uses dynamic braking to stop
the motors for precision motion control.
