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. RF Monitor

The RF Monitor is specially designed for use on off-road or wild land fire
fighting apparatus. The
transmitter or by handheld transmitter so risk to firefighters is significantly reduced.

The
stainless steel gears and motors that are completely enclosed and sealed for maximum
protection from the elements. The RF 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 RF control box. This enables “pump and roll” functionality with
complete control by the operator in the cab of the truck via wireless joystick control. The
electric valve can also be controlled using the optional handheld wireless transmitter.

RF features durable Elk-O-Lite® construction combined with rugged,

RF is controlled from inside the cab through a wireless

B. RF Receiver/Control Module

The monitor control circuit uses a state-of-the-art PIC (Programmable Integrated Circuit) chip
design. This device allows numerous control features while keeping circuit board size to a
minimum. Relays within this box provide motor reversing control for the Up/Down, Left/Right,
valve Open/Close and nozzle Straight Stream/Fog functions.
All functions are sent to the RF receiver/control module via an encoded radio frequency link.
The radio link reduces the number of control wires down to just the two power leads,
dramatically simplifying the installation procedure. The link also allows wireless control from
up to ¼ mile away using a battery powered handheld transmitter.

A rotary pulse counter, part of the horizontal motor, provides horizontal motion control
feedback. The counter in combination with the PIC controller enables the monitor to move
between programmable endpoints that are programmed by the user for rotation up to
360°total (+/- 180° from center). This feature also allows the unit to be programmed to
oscillate between positions within the total travel setting. This feature can be programmed
easily with any of the wireless transmitters. No mechanical stops to adjust.

The control circuit also provides secondary motor protection with the use of electronic current
sensing circuitry. If the monitor encounters an obstruction before reaching a pre-set limit,
this circuitry quickly senses motor stall current and automatically shuts off power to the
motor. As soon as the control switch is released, the circuit resets to allow subsequent
operation of the monitor.

Caution:

Any modification of the enclosure will destroy the NEMA 4 rating, and will void the warranty
coverage of the RF Receiver/Control Module.

The following additional functions/features are provided in the RF receiver/control module:

Reverse Polarity Protection: If battery connections are reversed, this feature

prevents power from being applied to circuits, and prevents damage to
electronic components.

Circuit Board Moisture Protection: In addition to being protected within a

NEMA 4 sealed enclosure, the circuit board and circuit components are
protected from moisture by an acrylic resin conformal coating.

C. RF Transmitters

The 8494 RF monitor uses W.E.T. (Wireless Electronic Technology), an innovative wireless
radio link, to send all commands from the RF transmitters to the RF Receiver/Control
Module. The new W.E.T. wireless link gives the operator the ability to view the discharge
stream and target from virtually any point of view. The 8494-RF monitor comes standard
with a joystick or a twin joystick transmitter. An optional handheld transmitter can be
purchased from Elkhart Brass and can be programmed to work with any W.E.T. enabled
monitor.

1. Primary Transmitter

The Sidewinder RF has two joystick transmitter options. Either joystick transmitter can be
used and will override the handheld transmitter.

81498001 Joystick Transmitter

(Figure 3) The RF joystick is suitable for
mounting inside the apparatus cab. The joystick
controls all four monitor functions plus
oscillation. Up/Down and Left/Right monitor
functions can be operated simultaneously. The
water valve is controlled with a trigger switch on
the front of the joystick. The water valve can
also be locked open by activating the button
located on the enclosure top. 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.
Oscillation is programmed by using the joystick
in conjunction with the oscillate button.

Caution: Joysticks are not environmentally sealed. They are meant for in cab use

only. Use outside of cab will void the warranty coverage.

2. Secondary Hand Held Transmitter

81502001 Handheld Transmitter
(Figure 4) A sealed handheld remote contains all the controls

necessary for operation of the monitor, oscillation, nozzle, and
water valve. 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 it is hitting the target. Separate
push button switches are provided for up, down, left, right, fog,
stream, valve open, and valve close 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.

Caution: Any modification of the enclosure of the handheld transmitter will destroy

the NEMA 4 rating, and will void the warranty coverage of the remote control.

D. 5000 Series Nozzles

Three constant flow electric nozzles are offered with the

RF monitor with flows ranging from 15
to 350 GPM. The nozzle pattern is electrically actuated
and controlled by the monitor control box. The 5000-04
Series nozzles have a flush feature to clear debris from
the nozzle without shutting down the water flow.
