III. SYSTEM COMPONENT DESCRIPTIONS
A. 8294-06 and 8394-07 Scorpion RF Monitors
(Figure 6) The 8294-06 Scorpion is a cast aluminum monitor with
4" waterway while the 8394-07 is cast brass. The waterway
contains a central vane to minimize large-scale turbulence and
provide superior fire streams. Monitor water supply connection is
a 4 inch 150 lb. ANSI pattern flange. The discharge nozzle
connection is 3-1/2 inch National Hose thread. Nozzle stream
direction is controlled by two permanent magnet type planetary
gear motors, one controlling rotation about the axis of the water
inlet, and the other controlling nozzle elevation and depression.
Right angle gear cases between the gear motor and the monitor
allow for convenient manual override of the electric motors in the
event of a power failure during firefighting operations. All
gearing is enclosed within the monitor housings.
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.
Figure 6
8294-06 Monitor with 284-A
and SM-2000E
B. 8294-06 EXT Scorpion RF Monitor
The extended travel Scorpion has the same highly efficient waterway and flow capacity as the
Scorpion RF monitor. The monitor waterway is supplied through a 4” 150# flat faced flange base.
The 8294-06 EXT monitor has a mechanical stop to allow 180º for added protection in an aerial
application.
The extended travel Scorpion RF has special features to optimize performance as an aerial master
stream device when used on a straight aerial ladder with pinnable waterway. The pinnable waterway
feature allows the waterway to be pinned to the second fly section of the ladder (egress position), thus
keeping the monitor and nozzle away from the end fly section when it is necessary to place the ladder
tip at a window sill or roof parapet.
The 8294-06 EXT contains a special wiring harness connection at the inlet flange to allow attachment
of an OEM provided proximity sensor. The proximity sensor is used to tell the monitor controller
which positions the waterway and monitor is. As a result, the monitor discharge Up-Down travel
range differs for the two waterway and monitor positions as indicated in Table 1.

5
Waterway/Monitor Position Up-Down Travel Range
Master Stream +80º to -135º
Egress 0º to –135º
Table 1
The 0º position is when the nozzle is aimed parallel to the ladder.
As a further enhancement, the left-right motor direction of rotation automatically reverses when the
monitor discharge is in the range of 0º to +80º. Without this feature, when the discharge travels above
0º, “left” would functionally become “right” and vice versa.
If the proximity sensor changes state while the monitor is in the “master stream” position and the
monitor discharge is in the 0º to 80º “up” range, the monitor controller will automatically lower the
discharge to 0º to prevent possible interference with the ladder, or impingement of stream upon
personnel.
Figure 7
8294-06 EXT Monitor
.
C. 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 and 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 up to ¼ mile away using a
battery powered handheld transmitter.

6
An encoder, part of the horizontal motor, provides horizontal motion control feedback. The counter in
combination with the PIC controller enables the monitor to oscillate between programmable endpoints
that are set directly from the remote transmitter.
The encoder enables the PIC controller to remember a home or stow position. This stow position can
be used as a storage position for the monitor during transport. Once the “Stow” feature is activated,
the monitor will automatically return to the home or stow position.
The control system also provides secondary motor protection with the use of electronic current sensing
circuitry. If the monitor encounters an obstruction before reaching a 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: The circuit board and circuit components are
protected from moisture by an acrylic resin conformal coating. All relays have sealed
covers.
D. RF Transmitters
The 8294-06, 8294-06 EXT, and 8394-07 monitors use W.E.T. (Wireless Electronic Technology), an
innovative wireless radio link, to send all commands from the RF transmitters to the monitor
controller. This new wireless link gives the operator the ability to view the discharge stream and target
from virtually any point of view within ¼ mile of monitor.
1. 81282001 Handheld RF Transmitter
(Figure 8) 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.

2. 81327011 Primary Panel Mount RF
Transmitter
(Figure 9) The fixed RF transmitter sends signals to the
monitor via an encoded radio signal, requiring no wires
between the RF transmitter and the monitor. It is powered
by the 12V or 24V vehicle electrical system. The faceplate
is intended for a flush mount onto the pump or aerial ladder
control panel. Separate sealed push button switches are
provided for up, down, left, right, fog, and stream functions.
This fixed RF transmitter provides two-button access to the
Stow feature. It will override any low-priority controls,
allowing the apparatus operator to retain ultimate control
over the monitor.
3. 81327001 Secondary Panel Mount RF
Transmitter
(Figure 10) The fixed RF transmitter sends signals to the
monitor via an encoded radio signal, requiring no wires
between the RF transmitter and the monitor. It is powered
by the 12V or 24V vehicle electrical system. The faceplate
is intended for a flush mount onto the pump or aerial ladder
control panel. Separate sealed push button switches are
provided for up, down, left, right, fog, and stream functions.

4. 81353011 OEM Primary RF Transmitter
(Figure 11) The OEM RF transmitter allows the monitor
installer to use their switching arrangement while still
having the benefit of the W.E.T. It has all of the same
features of the Primary Panel Mount RF transmitter, but has
a wiring harness for the installer to connect to the switches.
5. 81353001 OEM Secondary RF Transmitter
(Figure 11) The OEM RF transmitter allows the monitor
installer to use their switching arrangement while still

6. 81340001 Secondary Switch Box
Control for Aerial Applications
(Figure 12) This component is a surface mount type
switch box with controls for operation of the monitor for
use with the OEM secondary RF transmitter. Separate
sealed toggle switches are furnished for up-down, left-
right, and strt-fog functions. The box has a NEMA 4
rating, and is generally installed at the tip of the aerial
ladder, or in the bucket of the aerial platform. A
terminal strip inside the enclosure allows for connection
of the control cable, and a watertight strain relief fitting
provides for sealing around the cable entry.
7. 81392001 Auxiliary Battery Pack
A 12-volt, 12 amp-hr. sealed lead-acid battery pack is
available to allow operation of the monitor in case of
vehicle electrical system failure. These battery packs are
also used as a means to minimize the required size of
conductors routed up aerial ladders and towers. This is
accomplished by mounting the battery pack near the
monitor, with a small trickle-charge conductor to the
battery from the vehicle system.

V. INSTALLATION INSTRUCTIONS
A. Component Mounting
1. Monitor
a) 4” NPT Base: Apply an appropriate thread sealant to the 4” NPT nipple. Thread the
monitor base onto the nipple. Install with the "straight ahead" position properly aligned.
b) 4” 150# Flat Faced Flanged: Attach 4" 150 lb. class ANSI pattern companion flange to
water supply pipe so that bolt pattern will allow monitor to be installed with the "straight
ahead" position properly aligned. Alignment is correct when the "straight ahead" direction is
centered between adjacent flange holes. Attach monitor inlet flange to companion flange on
water supply pipe with eight (8) 5/8-11 UNC grade 5 carbon steel or stainless steel bolts, 2-1/2
inches long, with nuts. If a wafer type butterfly valve is installed between the monitor and the
companion flange, required bolt length will be 4-1/2 inches. Seal flange joint with gasket, or
suitable flange sealant. Most wafer type butterfly valves have seats that serve as flange
gaskets, and separate gaskets or sealant is not required. Apply Loctite® #242 to bolt threads,
then thread on nuts, and torque to 60-70 ft-lbs.
Warning: When installing monitor on a raised face companion flange, it is critical that
bolts be tightened uniformly to prevent cocking of the monitor relative to the flange or valve. If the
monitor becomes cocked, (see Figure 14) the monitor cast flange base will fracture and fail when the
bolts on the "high" side are tightened.

B. Communication Address Setup
A RF transmitter controls one 8294-06, 8294-06 EXT and 8394-07 monitors. The transmitter is
digitally encoded with a security code to ensure that it does not accidentally control the wrong
monitor. The receiver has a matching decoder and security code that instantaneously decodes and
interprets commands. The security code is a 15-bit selectable code that is set on both the remote
transmitter and the receiver.
The 8294-06, 8294-06 EXT, and 8394-07 monitors are tested and shipped with a security code based
upon the monitor serial number, ensuring each monitor leaves the factory with a unique code
assigned to it. The security settings will normally not need to be changed. In the case of a lost
transmitter or replaced control board, use the following instructions to change the security settings.
Danger: Using two W.E.T. monitors with the same, security code may cause the
inadvertent control of the wrong monitor, resulting in possible property damage and injury to
personnel. Using the factory specified codes will prevent this problem.
Caution: Do not pinch wires when attaching back panel to front panel of the handheld
enclosure. Ensure all O-ring and gaskets are properly installed when closing receiver or transmitter
enclosures.
C. RF Settings
Caution: The RF Receiver/Control Module and all transmitters’ communication addresses
have been set at the factory. They should not require any additional address settings.

1. RF Receiver/Control Module Settings
Remove the cover from the RF receiver/control module. SW4 (Figure 18) allows this board to be
used in different product applications. In order for it to properly operate the Scorpion RF monitor,
it must be set to:
1 8294-06 and 8394-07 Scorpion RF – Blinking Stow Indicator for Dash Panel
Indicator Application
2 8294-06 and 8394-07 Scorpion RF – Non-Blinking Stow Indicator for
Interlock Application
3 8294-06 EXT Scorpion RF
If it is set to a value that is not yet programmed, the status indicator LED, DS5 (Figure 18), will
blink rapidly until a valid setting is selected and power is cycled. If SW4 is set to a valid setting
but not one of the above positions, unpredictable results will occur.
