MONITOR

Scorpion RF Monitors – 8294-06 & 8394-07

The 8294-06 and 8294-06 EXT 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

3½” 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.

Scorpion RF Monitor – 8294-06 EXT

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 180° 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.

Waterway/Monitor

Position

Up-Down Travel Range

Master Stream +30° to -135°

Egress +0° to -135°

Table 1: EXT Travel Ranges

The 0° 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 0° to +30°. Without this feature, when the

discharge travels above 0°, “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 0° to 30° “up” range, the monitor controller will automatically

lower the discharge to 0° to prevent possible interference with the ladder, or impingement of

stream upon personnel.

Caution: All monitor motors are 12VDC. If using a non-Elkhart nozzle, another 12VDC

nozzle should be used, or nozzle control may not function properly.

NOZZLE

Scorpion RF Nozzles –

There are two nozzles available for the Scorpion RF.

SM-1250E & SM-2000E

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.

SM-1250E; 350 GPM @ 50 PSI – 1250 GPM @ 75 PSI

SM-2000E; 500 GPM @ 50 PSI – 2000 GPM @ 80 PSI

CONTROL

Handheld RF Controller – 81282001

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

SM-1250E (P/N: 03781211) &

SM-2000E (P/N: 03990201)

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.

Primary Panel Mount RF Controller – 81327101

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 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. Comes with 10 foot coax antenna

cable and (1) 90° antenna and (1) straight antenna.

Secondary Panel Mount RF Controller – 81327201

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 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. Comes with 10 foot coax antenna cable

and (1) 90° antenna and (1) straight antenna.

Caution: Any modification of the Handheld Controller or Panel Mount enclosures will

destroy the NEMA 4 rating to that piece of equipment and will void the warranty

coverage.

MONITOR ACCESSORY

Primary OEM RF Transmitter – 81353101

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

controller, but has a wiring harness for the installer to connect to

the switches. Comes with 10 foot coax antenna cable and (1)

90° antenna and (1) straight antenna.

Secondary OEM RF Transmitter – 81353201

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 Secondary Panel Mount RF

controller, but has a wiring harness for the installer to connect to

the switches. Comes with 10 foot coax antenna cable and (1)

90° antenna and (1) straight antenna.

Secondary Switch Box Control for Aerial Application –

81549001

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

Auxilary Battery Pack – 81492001

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

Caution: Any modification of the enclosures of any of the transmitters or switch box

will destroy the NEMA 4 rating, and will void the warranty coverage. Ensure all O-ring

and gaskets are properly installed when closing receiver or controller enclosures.

DC to DC Converter Function – 24272000

An optional 24 to 12VDC converter board can be added to the RF receiver control module

to allow 24 VDC power to the monitor. The converter will supply enough 12VDC power to

the monitor to run all motors simultaneously. It is reverse voltage protected and meets SAE

J1113-11 (Immunity to Conducted Transients on Power Leads) requirements.

INSTALLATION INSTRUCTIONS

Installation Overview:

Installation Step 1: Mount and Wire All System Components

Warning: It is up to the system designer to appropriately handle the open circuit

condition of the stow signal. In the open circuit mode there is no source to turn off the

stow signal load, which may lead to erroneous signal indications if not handled properly.

The stow signal is capable of sinking 250mA maximum. Exceeding this value may blow

the intern

al fuse and the stow output will no longer be able to provide a ground.

Important: Most test lights draw in excess of 1A.

Monitor Mounting –

 4” NPT Base: Thread monitor onto male 4” NPT thread using Loctite 592 or equivalent

thread sealant. Install the monitor in the straight ahead position.

 4”-150# Flat Faced Flange: Attach 4”-150# ANSI

pattern companion flange to water supply pipe so

that the bolt pattern will allow the monitor to be

installed in the straight ahead position. Alignment is

correct when the straight ahead position is centered

between adjacent flange holes. Attach monitor inlet

flange to companion flange on water supply pipe

with eight (8) 2½” 5/8-11 UNC grade 5, carbon steel

or stainless steel bolts & nuts. 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 or equivalent to bolt

threads before tightening nuts. Torque to 60-70 ft-lbs.

Warning: When installing the monitor on a raised face companion flange, it is critical

that the bolts be tightened uniformly to prevent misalignment of the monitor relative to

the flange or valve. If the monitor becomes misaligned, the base flange will fracture and

fail when the bolts on the “high” side are tightened.

RF Settings Setup

Monitor Wiring –

 Crimp a fused lead from a switched positive power source to the red lead (pin C) of

the power harness supplied. Use a 10A fuse for the 8294-06 & 8294-06 EXT, and a 15A

fuse for the 8394-07. Crimp a lead from the vehicle ground to the black lead (pin A) of

the monitor power harness. Shrink and seal the connectors with a heat gun after

crimping.

 The white lead (pin B) is for an optional “Stow Indicator” which could be attached to a

relay or LED supplied by the OEM. The circuit switches in a ground when the monitor is

in a non-stowed position.

 All control functions are sent to the monitor via an encoded RF signal from the RF

controller, and no control wiring is needed.

 The 8294-06 EXT has a proximity sensor. The red wire (pin C) supplies power, the black

lead (pin A) is the ground, and the white lead (pin B) is the signal for the proximity

sensor to show master stream versus an egress position.

Panel Mount RF Controllers –

 Using the Panel Mount RF Controller template in the Component Mounting Templates

section, mark the panel cutout and mounting screw locations.

 Cut a rectangular clearance opening and drill four (4) 7/32” holes.

 Insert fixed RF controller case through the panel cutout. Secure the unit to the panel

with four (4) #10-32 screws. The length of the screws should be the panel thickness plus

3/16”. The screws supplied are ¼” in length. Apply Loctite 242 or equivalent to screw

threads before tightening them.

 The controller antenna is to be mounted using the 10’ antenna cable provided.

Locate one of the antennas outside the vehicle compartment, and in a position that

provides the least obstructed line of sight to the monitor’s antenna.

 Place a 1A fuse between the red lead of the RF controller and a switched positive

power lead on the vehicle. Attach the black lead from the monitor base to the

vehicle ground.

 All control functions are sent to the monitor via an encoded RF signal from the RF

Controller.

OEM RF Transmitter –

 Place a 1A fuse between the red lead of the transmitter and a switched positive

power lead on the vehicle. Attach the black lead from the monitor base to the

vehicle ground.

 Connect all of the switch commons to the ground (black) connection.

 Connect each function to a corresponding switch (see Table 2 on page 11). To

operate the function, close function’s switch to ground. Any combination of

pushbuttons or toggle switches can be used.
