PRODUCT SAFETY INFORMATION

Important: Before installing and operating provided equipment, read this manual

thoroughly. Proper installation is essential to safe operation.

 All personnel who may be expected to use this equipment must be thoroughly trained in its safe and

proper use.

 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.

 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.

 Whenever possible, this equipment should be operated from a remote location. Do not needlessly

expose personnel to dangerous fire conditions.

 Open water valves supplying this equipment slowly so that piping fills slowly, thus preventing

possible water hammer occurrence.

 After each use, and on a scheduled basis, inspect equipment per instructions in the Maintenance

section.

 Any modifications to the electrical enclosures will destroy the NEMA 4 rating and void warranty

coverage of the enclosure and all components within.

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

SM-2000E (P/N: 03990201)

Scorpion RF LED Monitor – 8294-07 The 8294-07 is a cast aluminum monitor with 4” waterway. 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 Nozzles – There are two standard 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 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, 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

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

Caution: Any modification of the enclosure of the Position Feedback Display will

destroy the NEMA 4 rating, and will void the warranty coverage.

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.

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 a 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 lowpriority controls, allowing the apparatus operator to retain ultimate control over the monitor.

Position Feedback Display – 81584000 The Scorpion RF monitor comes with serial Position Feedback sensors.

These sensors provide feedback to the monitors’ processor even when

the monitor is moved via manual override. This information is then transmitted to the Position Feedback Display.

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.

Step 1 – Mount and Wire All System Components

Step 2 – Communication Address Setup

Step 3 – RF Settings Setup

Step 4 – System Programming

Installation Overview:

Monitor Mounting –

 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.

Monitor Wiring –

 Place a 10A fuse between the red lead (pin C) of the monitor and a switched positive power

lead on the vehicle. Attach the black lead (pin A) from the monitor base to the vehicle ground.

 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 8294-07 has a serial position feedback display. On the Deutsch DTM04-3P connector, the

red wire supplies power, the black wire supplies ground, and the third pin is a plug. On the Deutsch DT04-2P connector, the blue wire is signal for the position feedback display, and the black wire is ground.

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.

 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.
