Summary of operation
The module is particularly designed for the use in vehicles compatible
to the Faller* car system, that are run with two accumulator batteries. It
has six in- and outputs for the connection of LEDs, motor, reed contact
and a loudspeaker. Additional white LEDs for the front lighting can be
connected to the additional output. It is not necessary to use all
outputs. The in- and outputs are controlled from the software stored in
the IC. The software is designed for controlling an emergencyvehicle.
The voltage of 2,4 V that is provided by the vehicle accumulator batteries, is
doubled by the module. This enables white and blue LEDs to be connected,

FCS-4 English
Page 23
which normally need a voltage of more than 2,4 V. Red and yellow LEDs
may be connected directly via series resistors to the accumulator batteries,
provided they are not to be controlled by the software.
Front lighting
There can be connected up to two additional white LEDs for the front
lighting to the additional output. These LEDs are not controlled by the
software.
N.B. In contrast to the LEDs connected to the outputs controlled by the
software these should be connected via series resistors. Otherwise the
connected LEDs are damaged and the circuit may not work as intended.
Back lighting
It is possible to connect two red LEDs to one output of the module for
the back and stop lights. While breaking and some seconds after
stopping, the back lights are switched brighter, provided that the reed
contact existing in the vehicle is connected to the module.
Flashing lights
It is possible to connect two LEDs to one output of the module for the
flashing lights. These flash shortly two times each alternately and go off
again for a short time. The flashing lights are in operation as long as
the vehicle is supplied with voltage.
Siren
It is possible to connect a loudspeaker to one output of the module
which is switched on and off in short intervalls while the vehicle is in
motion. If the reed contact existing in the vehicle is connected to the
module the loudspeaker is switched off when the vehicle stops and
switched on while starting.
Driving of the motor
The reed contact that is in the vehicle can be connected to the module.
The module then influences the motor: After a stop it starts gently.
Additionally the back lights are switched brighter while the vehicle is
stopping and a few seconds after a halt and the siren is switched off.

Required tools and materials
Make sure you have the following tools and materials ready for use:
§an electronic soldering iron (max. 30 Watt) with a fine tip,
§a soldering iron stand,
§a tip-cleaning sponge and a heat-resistant mat,
§a small side cutter and wire stripper,
§a pair of tweezers,
§tin solder (0,5 mm. diameter),
§enamelled copper wire or thin connecting wire,
§LEDs for the lights,
§if necessary: series resistors for the front lights.
Safe and correct soldering
Caution:
Incorrect soldering can cause dangers through fires and heat. Avoid
these dangers by reading and following the directions given in the
chapter Safety instructions. If you have had training in soldering you
can skip this chapter.
§Use a small soldering iron with max. 30 Watt. Keep the soldering tip
clean so the heat of the soldering iron is applied to the solder point
effectively.
§Only use electronic tin solder with flux.
§When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
§Solder quickly: holding the iron on the joints longer than necessary
can destroy components and can damage copper tracks or
soldering eyes.
§Apply the soldering tip to the soldering spot in such a way that the wire
and the soldering eye are heated at the same time. Simultaneously add
solder (not too much). As soon as the solder becomes liquid take it

English FCS-4
Page 26
away. Hold the soldering tip at the spot for a few seconds so that the
solder flows into the joint, then remove the soldering iron.
§The joint should be held still for about 5 seconds after soldering.
§To make a good soldering joint you should use a clean and
unoxidised soldering tip. Clean the soldering tip with a damp piece
of cloth, a damp sponge or a piece of silicon cloth.
§After soldering check (preferably with a magnifying glass) tracks for
accidental solder bridges and short circuits. This would cause faulty
operation or, in the worst case, permanent damage. You can
remove excess solder by putting a clean soldering tip on the spot.
The solder will become liquid again and flow from the soldering
spot to the soldering tip.
Special features of the additional components
Resistors
Resistors reduce current. Their mounting orientation is of no
importance. The value of resistors for smaller power ratings
(under 5 W) is indicated through colour rings. Every colour
stands for another figure. The added resistor has a value of
10 kΩ (colour rings brown - black – orange – gold).
Diodes
Diodes allow the current to pass through in one direction only
(forward direction). The diode type is printed on the body.
Diodes must be mounted in a given direction. The negative
end is marked with a ring.
Transistors
Transistors are current amplifiers which convert low signals
into stronger ones. They have three contacts. As they are
polarized, they have to be mounted in a certain direction. Die
BC-Types have a housing in form of a half cylinder (SOT-
housing). The three connecting points are called basis (B),
collector (C) and emitter (E).

FCS-4 English
Page 27
Light emitting diodes (LEDs)
When operated in the forward direction the LEDs light. They
are available in several different versions (differing in colour,
size, form, luminosity, maximum current, voltage limits). The
longer lead of wired LEDs is always the anode (positive pole).
With SMD-LEDs the cathode normally is shown by a mark on
the housing.
Light emitting diodes should always be connected via a series
resistor which limits the current and prevents failure. With
circuits designed for the connection of LEDs the series
resistors are often integrated on the circuit board.
Reed contacts
Depending on their version reed contacts fulfill the task of a
closer or a change-over switch. They respond to a magentic
field, thus making possible contactless switching operations.
They consist of a glass bulb filled with a protective gas.
Sealed in the glass bulb are two or three reeds made of a
magnetic material. When bending the legs the glass bulb they
can be easily damaged through mechanical strain.
Mounting the FCS-4
Preparation
Open the housing of the vehicle. Locate the position for the module.
Disconnect all connections from the accumulator batteries, the motor and
the mounted reed contactexcept for the wire to the charging contact.
Follow the connection diagram fig. 2 (page II in the centre of this
handbook) and the special features of the addional components.
In many vehicles the resistor R7 shown in the connection diagram is
mounted into the lead-in wire to the motor. The resistor has to be
connected to the plus pole of the accumulator batteries if not yet
mounted that way. If there is no resistor, R7 is not applicable.

English FCS-4
Page 28
!
Connection to the supply voltage
Connect the connecting point X2 to the plus pole of the accumulator
batteries and the minus pole of the accumulator batteries to the
existing switch S of the vehicle. Connect the second pole of the switch
to the connecting point X1.
Caution:
The module should not be connected the wrong way round. Otherwise
it will be destroyed when put into operation.
Connection of the existing reed contact
The existing reed contact has three connecting points, one at side A
and two at side B. Connect the connecting point at side A to the
connecting point X1 and the existing switch S.
In order to check which one of the two connecting points of side B you
have to connect to the module, connect temporarily the plus pole of the
motor to the plus pole of the accumulator batteries and the minus pole
of the motor to one of the two connecting points at side B of the reed
contact. If the motor does not run with this connection, you have to
connect this connecting point to the plus pole of the motor and the
other connecting point of the reed contact with the connecting point X9
and the enclosed resistor R10. If the motor runs with this connection,
you have to make the connections the other way round. Connect the
second side of the resistor R10 to the connecting point X3.
Connection of the motor
Connect the enclosed diode 1N4148 to the connections of the motor.
Observe the polarity of the diode. Then connect the minus pole of the
motor to the minus pole of the accumulator batteries. Next connect the
collector (C) of the enclosed transistor BC 327 to the plus pole of the
motor, the basis (B) to the connecting point X7 and the emitter (E) to
the resistor R7. If there is no resistor R7, connect the emitter directly to
the plus pole of the accumulator batteries.

Connection of the LEDs for the flashing lights
Connect the anodes (+) of the two LEDs for the flashing lights to the
connecting points X4 and X5. Connect the cathodes (-) of the LEDs both
to the connecting pointX3.
Connection of the LEDs for the stop and back lights
The two LEDs for the stop and back lights have to be connected in series,
i.e. the anode (+) of the one LED has to be connected to the cathode (-)
of the other LED. Next connect the disconnected anode with connecting
point X8 and the disconnected cathode with connecting point X3.
Connection of the loudspeaker
First connect the basis (B) of the enclosed transistor BC 327 to the
connecting point X6, the emitter (E) to the plus pole of the accumulator
batteries and the collector (C) to the plus pole of the loudspeaker. Next
connect the minus pole of the loudspeaker to the connecting point X1. If
the polarity of the loudspeaker is not given, you may connect it anyway.
You can reduce the sound volume of the loudspeaker by mounting a
resistor between the collector of the transistor and the plus pole of the
loudspeaker. The resistor should have a value of 10 to 100 Ohm.
Connection of the diodes for the front light
You may connect up to two white LEDs for the front lighting to the
voltage output of the module. These LEDs are not controlled by the
stored software. They light as soon as the module is connected to the
power supply. Follow the connection diagram fig. 2!
Connect the anodes (+) of the LEDs to the soldering point X2 and the
cathodes (-) to the soldering point X3.
Caution:
The LEDs for the front light, which are connected to the voltage output
must be operated via series resistors! Otherwise the connected LEDs
are damaged and the circuit may not work as intended.

English FCS-4
Page 30
!
Computation of the series resistors for the front light LEDs
In order to spare the accumulator batteries it is recommended to
restrict the input of the LEDs for the front lighting to approx. 10 mA.
This guarantees as well a sufficient brightness. In this case you can
determine the series resistor from the following formula:
R = (UB- UF) / I = (4,8 - UF) / 0,01
R: necessary series resistor [Ohm]
UB: voltage at the voltage output of the circuit [V]
UF: forward voltage of the LED [V]
I: Current through the LED [A]
Example for a LED with UF= 4 V:
R = (4,8 – 4,0) / 0,01 = 80 Ohm
As the calculated value in this example does not correspond to a
commercial resistor we choose the next lower value, that means a
resistor of 68 Ohm.The input of the LED then is ca. 12 mA.
