SAFETY MESSAGE TO INSTALLERS
People’s lives depend on your safe installation of our products.
It is important to read, understand and follow all instructions
shipped with the products. In addition, listed below are some other
important safety instructions and precautions you should follow:
• To properly install this light: you must have a good
understanding of automotive electrical procedures
and systems, along with proficiency in the installation and use of safety warning equipment.
• DO NOT install equipment or route wiring in the
deployment path of an air bag.
• When drilling into a vehicle structure, be sure that
both sides of the surface are clear of anything that
could be damaged.
• In order for the light to function properly, a good
ground connection must be made. At a minimum, it
must be attached to a solid metal body or chassis
part that will provide an effective ground path as
long as the light system is to be used.
• Locate light control so the VEHICLE and CONTROL can be operated safely under all driving
conditions.
• Do not attempt to activate or deactivate light control
while driving in a hazardous situation.
• This product controls high intensity LED devices. To
prevent eye damage, DO NOT stare into the light
beam at close range.
• You should frequently inspect the light to ensure
that it is operating properly and that it is securely
attached to the vehicle.
• File these instructions in a safe place and refer to
them when maintaining and/or reinstalling the
product.
Failure to follow all safety precautions and instructions may
result in property damage, serious injury, or death to you or
others.
I. GENERAL.
The Federal Signal SignalMaster Model 331102 is an
economical, low profile, solid state, directional light control that is
designed to operate with any of Federal Signal’s SignalMaster
series eight-lamp directional lights. This control will also operate
two sets of external lamps (Federal Signal Models 320102,
SMLED1, 320112, and 320721, or other 50 watt lamps). The unit
is reversed polarity protected to avoid damage if the positive and
negative power connections are connected incorrectly.
This model provides three distinctive directional signals, left
arrow, right arrow, and center out. An alternating flash pattern
produces a warning signal for use when a directional signal may
not be appropriate. In addition, an auxiliary flash pattern
alternately flashes the external lamps. The directional and
alternating flash patterns can also be selected to operate faster, or
with decreased current draw. The slide switch overrides the
WARN and AUX functions.
When normal directional signal operation is selected, the
lamps individually activate sequentially in a sweeping motion
until all eight are illuminated. When LOW (current) operation is
selected, the lamps turn on/off in sequence until a pattern is
completed. When FAST is selected, the chosen pattern sequences
at an increased rate.
FOR
An auxiliary input and output are provided for integrating
external controls and lights into the SignalMaster system. When
properly connected, a positive (+) 12 volts applied to the AUX IN
terminal will activate the alternating flash pattern. The AUX OUT
terminal can activate a ground-activated relay (user-supplied)
when the AUX switch is operated.
WARNING
These lights are intended for secondary warning only.
They are not intended for use as a primary warning
system.

III. INSTALLATION.
A. SignalMaster Light Assembly.
Install the light assembly as described in the instructions packed with the 320340 universal mounting kit. Route the
cable near the eventual location of the control unit.
B. Control Unit.
WARNING
When installing equipment inside air bag equipped vehicles, the installer MUST ensure that the equipment is
installed ONLY in areas recommended by the vehicle
manufacturer.
Failure to observe this warning will reduce the effectiveness of the air bag, damage the air bag, or potentially
damage or dislodge the equipment, causing serious injury
or death to you or others.

control unit to be mounted in a variety of positions. To install the
See figure 1. The supplied mounting bracket allows the
control unit, proceed as follows:
CAUTION
Install the control unit in an adequately ventilated area.
Never install near heater ducts.
NOTE
When selecting a mounting location for the control unit,
it is necessary to keep in mind the SignalMaster cable
length. Plan wiring and cable routing before installation.
1. Select a mounting location for the control unit that
allows the vehicle and controls to be operated safely at all times.
2. Use the mounting bracket as a template and scribe
two drill position marks at the selected mounting location.
CAUTION
Before drilling holes in ANY part of a vehicle, be sure that
both sides of the mounting surface are clear of parts that
could be damaged; such as brake lines, fuel lines, electrical
wiring or other vital parts.
3. Drill two holes at the previously scribed position
marks.
4. Secure the mounting bracket to the mounting
surface with two user-supplied, thread-forming, 1/4-20 screws.
C. Electrical Connections.
WARNING
Failure to observe this WARNING may result in fire,
burns or blindness.
If shorted to vehicle frame, high current conductors can
cause hazardous sparks resulting in electrical fires or
molten metal.
DO NOT connect this system to vehicle battery until ALL
other electrical connections are made and mounting of all
components is complete.
Verify that no short circuits exist, before connecting to the
Positive (+) battery terminal.

WARNING
Do not connect more than one, 6 or 8 head, halogen
SignalMaster assembly to a SignalMaster controller or the SignalMaster outputs of a SmartSiren.
Electrical fire or damage to the controller or siren
will result.
The control unit is supplied with a seven-position
connector, an eleven-position connector, and insulated spade
connectors (0.250" (1) and 0.187" (2)) to perform the electrical
installation. User-supplied, 14-gauge red and black wires are
required for the (+) BAT and (-) GND connections. User-supplied,
18-gauge red and green wires are required for the (+) IGNITION
and (-) CASE GROUND connections on the seven-position
connector. In addition, user-supplied 18-gauge wire is used for the
AUX IN, AUX OUT, and DASH LIGHTS connections. Using figure
2 as a guide, complete this portion of the installation as follows:
1. Power Connections.
CAUTION
To avoid damage and ensure proper operation, the red
and black wires MUST be installed as shown in figure 2.
a. Strip 1/4" of insulation off of each 14AWG red
and black wire. See figure 2. Crimp a 0.187" wide spade receptacle
on the red wire. Crimp the 0.250" wide spade receptacle on the
black wire.
b. Connect the red and black 14-gauge terminated
wires to the +BAT and GND positions as shown in figure 2.
c. Route the red and black 14-gauge wires
through the firewall and toward the battery. Connect the black
wire to a good frame ground near the battery. In most vehicles, a
wire from the negative terminal of the battery is routed and
attached to the body/frame at the fender. This is a convenient
point to connect the 14-gauge black wire. Do not connect the red
wire to the (+) positive terminal at this time.
d. Connect the 18-gauge red (IGNITION) and
green (CASE GROUND) wires to the connector as shown in figures
2 and 3.
IMPORTANT
The (+) IGNITION (18-gauge red) wire’s termination
point determines when the directional signal can be
activated. When the wire is attached to a vehicle fuse
that is powered when the ignition switch is in the run or
start position, the vehicle’s ignition switch must be in the
run or start position to operate the directional signal.
When the wire is attached to the vehicle battery, the
directional signal can be operated at any time. Note that
the unit draws no current when in the “off” position.
