Introduction
The RMX™ Lightbar is approximately 5.4" high and delivers 360° of unobstructed warning signal. PriZm II™ refl ector technology
means more signal power and versatility than any other lightbar of its size.
The aerodynamic lines reduce air drag, which results in fuel savings and stability at high speeds. This lightbar has a strong extruded
internal frame, shock-resistant polycarbonate lenses, and warning signals that exceed SAE standards.
The RMX has room for numerous LED options. While we do not recommend a light installed in every location, the design of the RMX
offers the ultimate fl exibility in the location of warning and auxiliary lights.
The use of this or any warning device does not ensure that all drivers can or will observe or react to an
emergency warning signal. Never take the right-of-way for granted. It is your responsibility to be sure you can
proceed safely before entering an intersection, driving against traffi c, responding at a high rate of speed, or
walking on or around traffi c lanes.
WARNING!
The effectiveness of this warning device is highly dependent upon correct mounting and wiring. Read and
follow the manufacturer’s instructions before installing or using this device. The vehicle operator should insure
daily that all features of the device operate correctly. In use, the vehicle operator should insure the projection
of the warning signal is not blocked by vehicle components (i.e.: open trunks or compartment doors), people,
vehicles, or other obstructions.
This equipment is intended for use by authorized personnel only. It is the user’s responsibility to understand
and obey all laws regarding emergency warning devices. The user should check all applicable city, state and
federal laws and regulations.
Code 3, Inc., assumes no liability for any loss resulting from the use of this warning device.
Proper installation is vital to the performance of this warning device and the safe operation of the emergency
vehicle. It is important to recognize that the operator of the emergency vehicle is under psychological and
physiological stress caused by the emergency situation. The warning device should be installed in such a
manner as to: A) Not reduce the output performance of the system, B) Place the controls within convenient
reach of the operator so that he can operate the system without losing eye contact with the roadway.
Emergency warning devices often require high electrical voltages and/or currents. Properly protect and use
caution around live electrical connections. Grounding or shorting of electrical connections can cause high current arcing, which can cause personal injury and/or severe vehicle damage, including fi re.
PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO ENSURE THE SAFETY OF EMERGENCY PERSONNEL AND
THE PUBLIC.
Wiring Instructions (Read Carefully Before Installation)
2
Unpacking & Pre-Installation
Carefully remove the lightbar and place it on a fl at surface, taking care not to scratch the lenses or damage the cable coming out of
the bottom. Examine the unit for transit damage, broken lamps, etc. Report any damage to the carrier and keep the shipping carton.
Standard lightbars are built to operate on 12 volt D.C. negative ground (earth) vehicles. If you have an electrical system other than 12
volt D.C. negative ground (earth), and have not ordered a specially wired lightbar, contact the factory for instructions.
Test the unit before installation. To test, touch the black wire to the ground (earth) and the other wires to +12 volts D.C., in accordance
with the instructions attached to the cable (an automotive battery is preferable for this test). A battery charger may be used, but please
note that some electronic options (fl ashers, etc.) may not operate normally when powered by a battery charger. If problems occur at
this point, contact the factory.
Installation & Mounting
Utilizing non-factory supplied screws and/or mounting brackets and/or the improper number
of screws may result in loss of warranty coverage on the equipment.
WARNING!
MOUNTING HARDWARE - Mounting hardware is usually packed in a small box inside the main carton although some mounting kits
may be shipped separately. Refer to the Installation Manual included in the mounting kit for mounting instructions. Note: Hook-on
mounting for "gutterless" type vehicles will require a special hook for mounting. Several special application hooks are available. Contact the factory for details.
Wiring Instructions
Larger wires and tight connections will provide longer service life for components. For high current wires it
is highly recommended that terminal blocks or soldered connections be used with shrink tubing to protect
the connections. Do not use insulation displacement connectors (e.g. 3M® Scotchlock type connectors).
Route wiring using grommets and sealant when passing through compartment walls. Minimize the number
WARNING!
Before attempting to connect wiring, refer to wire tag attached to the lightbar's main cable. Each wire in the cable controls a
separate lightbar function as described in the wire tag.
of splices to reduce voltage drop. High ambient temperatures (e.g. underhood) will signifi cantly reduce the
current carrying capacity of wires, fuses, and circuit breakers. Use "SXL" type wire in engine compartment.
All wiring should conform to the minimum wire size and other recommendations of the manufacturer and
be protected from moving parts and hot surfaces. Looms, grommets, cable ties, and similar installation
hardware should be used to anchor and protect all wiring. Fuses or circuit breakers should be located as
close to the power takeoff points as possible and properly sized to protect the wiring and devices. Particular
attention should be paid to the location and method of making electrical connections and splices to protect
these points from corrosion and loss of conductivity. Ground terminations should only be made to substantial chassis components, preferably directly to the vehicle battery. The user should install a fuse sized
to approximately 125% of the maximum Amp capacity in the supply line to protect against short circuits.
For example, a 30 Amp fuse should carry a maximum of 24 Amps. DO NOT USE 1/4" DIAMETER GLASS
FUSES AS THEY ARE NOT SUITABLE FOR CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit
breakers are very sensitive to high temperatures and will "false trip" when mounted in hot environments or
operated close to their capacity.
Route the wiring cable into the engine or passenger compartment, taking care to use grommets and to apply sealant around
openings to keep water out. It is advisable to leave an extra loop of cable when installing the lightbar to allow for future changes
or reinstallations. Connect the black lead to a solid frame ground (earth), preferably, the (-) or ground (earth) side of the battery
and bring the other wires to the control head or switches. Connect the wires as directed by the wiring instructions on the cable.

into light beam at close range.
LED Fusing Considerations
Although the average current draw per module is very low, due to the type of circuit used to power each module the instantaneous
peak current to a module can be signifi cantly higher during low voltage conditions. To avoid prematurely blowing ATO style fuses or
tripping breakers, it is recommended the following rule-of-thumb be used to size fuses or breakers. This is especially important in
lightbars with many LED modules running off a single fused source.
Minimum fuse size calculation:
1.5 x (number of modules being fused)
Example:
RMX Lightbar with 2 corner modules (2 per module) and 14 directional modules.
Minimum fuse requirement for single fuse - 1.5 (2+2+14) = 27A minimum
