Connecting the N8084 Rapid-sequencing 6-LED Emergency Vehicle Lightbar
Installing the N8084 is very straightforward. Because the module has circuitry on both sides, care must be taken to be sure that the components or wires soldered will not make contact with any metal object which could cause a short circuit. Included with the module are two 6” lengths of #32 insulated wire. If necessary, these can be used for power input wires. If used, we recommend the red wire be used for the + DC connection. It would be connected to solder point 1 as shown in Fig. 1. This wire could also connect through a switch to the + DC connection for remote control of the lighting effect. The other (black) wire should be connected to – DC and to solder point 2. Any well regulated DC power source can be used to power this module providing the voltage is at least 6VDC and doesn't exceed 18VDC. Our N3512 and N3518 Power supplies are ideal for this use. Also, due to the very low power consumption, this device can also be powered by a battery, such as a standard 9-volt.
Figure 1 Important note: A low-wattage iron with a pointed tip should be used for connection of wires. Too much heat or solder can easily damage the wires, decoder or module and void the warranty. Also, all connecting wires should be pre-tinned before soldering them to the module. This will make connection quick and easy and ensure excessive heat is not applied to the solder points.
Connecting LEDs
When
connecting the LEDs, proper polarity must be observed. LEDs are “polarity
sensitive” and will not function if connected backwards.
The N8084
is
configured to connect
six
(6)
20 ma LEDs (3
series pairs)
in any mix of red, yellow or orange LEDs, between
solder points
3 through 6
as shown in Figure 2 below.
These LEDs will use the on-board current protection resistor so no external
resistor is necessary.
Using wire
appropriate for the size of the LEDs and their placement in your project.

This completes connection of the N8084 module. It is recommended that a thorough re-inspection of all connections and module placement be performed prior to applying power. We hope you enjoy the added realism our module provides. © 2020 Ngineering |
