I. PRODUCT SAFETY
Important:
Before installing and operating this equipment, read & study this manual thoroughly.
Proper installation is essential to safe operation. In addition, the following points
should be adhered to in order to ensure the safety of equipment and personnel:
1. All personnel who may be expected to use this equipment must be
thoroughly trained in its safe and proper use.
2. Before flowing water from this device, check that all personnel (fire
service and civilian) are out of the stream path. Also, check to make
sure stream direction will not cause avoidable property damage.
3. Become thoroughly familiar with the hydraulic characteristics of this
equipment, and the pumping system used to supply it. To produce
effective fire streams, operating personnel must be properly trained.
4. Whenever possible, this equipment should be operated from a remote
location. Do not needlessly expose personnel to dangerous fire
conditions.
5. Open water valve supplying this equipment slowly
fills slowly, thus preventing possible water hammer occurrence.
6. After each use, and on a scheduled basis, inspect equipment per
instructions in section VI.
7. Any modifications to the electrical enclosures will destroy the NEMA 4
rating and void warranty coverage of the enclosure and all components
within.

II. SYSTEM COMPONENT DESCRIPTIONS
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
gears and motors that are completely enclosed and sealed for maximum protection from the elements.
The
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
operator in the cab of the truck.
features durable Elk-O-Lite® construction combined with rugged, stainless steel
has a flow efficient 2.0” vaned waterway to minimize turbulence and provide
control box. This enables “pump and roll” functionality with complete control by the
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.

C. 81122001 Standard Control Box
The standard control box consists of a weathertight enclosure with toggle switches that is suitable
for mounting inside or outside the apparatus. The
toggle switches control the water supply (On-Off),
monitor direction (Left-Right and Up-Down), and
nozzle pattern (Straight Stream-Fog).
D. 81172001 Joystick Control Box
(Optional)
The joystick control box is suitable for mounting
inside the apparatus cab. The joystick controls all
four functions. The water supply is controlled
with a trigger switch on the front of the joystick.
The water can also be run continuously by
activating the toggle switch mounted on the
enclosure. Nozzle pattern is changed using the
rocker switch on the top of the joystick. The
monitor direction is changed by moving the
joystick in the desired direction.

E. 5000 Series Nozzles
Three constant flow electric nozzles are offered
with the
ranging from 15 to 350 GPM. The nozzle pattern
is electrically actuated and controlled by the
monitor control box.

F. 81181001 Water Valve Kit (Optional)
The water valve kit provides a
convenient remote on-off control of the water
supply to the 8494 . This allows the
operator complete control of the unit from the
safety of the vehicle cab. It also allows a “pump
and roll” capability. The water valve motor
prevents water hammer, yet closes quickly enough
to help preserve the limited on-board water supply.
The 81181001 Water Valve Kit is for 12VDC use
only. The 81298001 Water Valve Kit (24V) is
available for use with 24VDC systems. It includes
a 24-12 volt converter to power the water valve
and control module.
G. SM-10FE De/Anti-Icing Nozzle
Designed for the aircraft deicing industry, this
nozzle has been designed for use with type 1 deicing, type 2 anti-icing, or type 4 anti-icing fluids.
The SM-10FE has Viton® O-rings to withstand the
use of the Ethylene Glycol and Propylene Glycol
solutions used to de-ice aircraft. The nozzle is
constant gallonage at pressures below 90 Psi and
becomes automatic at 95 Psi. It is designed to
deliver 20 GPM at 50 Psi and 30 –120 GPM from
90-110 Psi.
Available in 12 VDC or 24 VDC.
