Code 3® PriZm II™ LED Reflector 360° Corner Modules
The RX 2700 Lightbar is equipped with new Code 3® PriZm II™ LED Reflector 360° corner LED modules that provide a full
360° of warning. The lighthead has been designed to exceed all applicable requirements for 360° warning devices in Red,
Blue, Amber and White.
Operating Specifications for 360° module:
Operating Voltage: 10-16 VDC, Reverse Polarity Protection
Current Draw :
Red/Amber - .5A avg @ 12.8 Volts
Blue/White - .8A avg @ 12.8 Volts
Available Colors - Red, Blue, Amber and White
Master/Slave Operation (See Directional Modules section below if so equipped)
Some 360 degree corner modules consist of a "master" and a "slave" driver circuit board and LED light engines with a single
integrated heatsink bracket. The "master" circuit board (rear position) must always be powered for the "slave"(front position)
to flash. The "master" is always located in the rear position of the module. The lightbar is wired to allow running only the rear
facing LED on each module by removing power to the front facing "slave" module. This gives a "front-cutoff" function. The
flash pattern for each corner pair can be selected by shorting together the 2-pin header J1, on the "master" momentarily and
releasing. The module is set-up for "Cycle Flash" as a standard. Holding down the 2-pin header for 5 seconds, or longer, and
releasing will return the pattern to Cycle Flash. The following chart describes the available patterns and order (Both heads will
be in the mode selected. Both heads will flash together unless in Front Cut-off mode):

LED DIRECTIONAL MODuLES
In addition to the 360 warning modules the lightbar may be equipped with a number of single head front-rear warning LED mod-
ules. These modules are available in either the, PriZm II LED REFLECTOR Module, 3-LED REFLECTOR, 3-LED OLP OPTIX
(dual stack 3-LED lightheads) in steady-burn and flashing versions. The steady-burn versions can be flashed by connecting the
module(s) to any flasher that does not require ground through the load (example: Code 3® 900 series flasher). The flashing
modules will have "Cycle Flash" as the standard pattern. The flash pattern can be changed by shorting the 2-pin header, J1 as
shown in Figure 1, momentarily then releasing. Table 1 shows the available patterns and the order when stepping through pat-
terns. The module can be reset to "Cycle Flash" by shorting the header for greater than 5 seconds and releasing.
See next page for operating specifications and available colors for front-rear modules.
Dim Operation
Lightbar LED modules are equipped with a low power "Dimming" mode. Dimming will be controlled by applying +12V by way of the
appropriate wire(color) in the wire harness/wire list. When DIM is engaged the LED's will operate in a reduced power mode. For
safety purposes, the corner modules in lightbars are not connected to the dimming circuit. This ensures that when corner modules
are turned on, full 360 degree coverage and compliance with SAE warning light standards is provided. The DIM control wires(two
white wires) located on each of the modules are connected from one module to the next. To disable the dimming function on a
particular module, disconnect the white wires. Then reconnect the white wire to the white wire on another module that has dimming
enabled.
The Dim setting reduces the light output of emergency warning lights reducing the effectiveness of
them especially in brightly lit areas. Failure to use adequate light for the circumstances can cause
motorists to fail to see the emergency vehicle and lead to serious personal injury or death. Never
use the DIM setting in a brightly lit area. Use of the DIM setting may cause emergency lights to not
comply with applicable emergency warning light standards. Use caution when using the DIM setting to
assure that motorists can clearly see the emergency vehicle.
