L.E.D. 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 significantly 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:
LED X 2100 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
OPTIONS & SPECIFICATIONS
Many options are available for the LED X 2100. This section is designed to describe the function of the various LED X 2100
options.
LED WARNING 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.
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.
!
WARNING!
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.
- Refer to the control head manual packaged with the lightbar for control
head installation and operation instruction.
Arrowstik® / Narrowstik®
OPTIONAL HALOGEN ARROWSTIK® (7-wire) / L.E.D. NARROWSTIK® (11-wire) WIRING AND CONTROL HEAD INSTALLATION -
After installation of the lightbar, route the smaller of the two power cables through the vehicle to the location chosen for the control
head. Cut the cable to length and strip back the outer insulation to expose the seven or eleven colored wires. Strip back 1/8” - 1/4” of
colored insulation from each of the wires in the cable. Connect these wires to the seven position / eleven position terminal plug
enclosed in the user parts bag, according to the diagram on the bottom of the control head.
