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.

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.

Table 1: EXT Travel Ranges

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.

SM-2000E (P/N: 03990201)

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.

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 (SM1250BE 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

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 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 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 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 lowpriority 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

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.

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.

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

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

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

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.
