Connecting the N8087 Early-era Emergency Vehicle Alternating Strobe for 6 LEDs

The N8087 is designed to generate a flashing emergency light effect between three series pairs of LEDs. The LEDs are connected to outputs (solder points 3 - 6) and power is applied to inputs (points 1& 2). this effect reproduces the early-era incandescent (bulb type) of flashes seen on many emergency vehicles.

Installing the N8087 module 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.

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 N3512B 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.

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

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.

When connecting the LEDs, proper polarity must be observed. LEDs are “polarity sensitive” and will not function if connected backwards. The N8087 is configured for the connection of three 20 ma LED series pairs of Red & Blue LEDs to solder points 3, 4 & 5 and 6

The N8087 has on-board current limiting resistance to protect these LEDs so no external resistor is required.

Using wire appropriate for the size of the LED and its placement in the model, wire the first series pair by connecting the first LED anode (the + connection) to solder point 4. Connect the cathode (- connection) of this LED to the anode of the second LED and connect the cathode (- connection) of the second LED to solder point 6. Repeat this wiring method for the second and third series pairs as shown below in Figure 2.

Once again, be sure to use a low-wattage soldering iron when connecting wires to the module.

LEDs are noted with "A" = Anode and "C" = Cathode

This completes connection of the N8087 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.
