Overview
The Model 330104 SMC1 is a directional light controller. It is designed to operate the full selection of
Federal Signal SignalMaster directional light bars from four to eight light heads, either continuous or split,
at 12V or 24V. The control circuitry is protected against reverse polarity by a 2 A fuse and a diode. The
light bar requires its own appropriately sized fuse.
This model provides six distinctive directional signals. There are standard left-arrow, center-out, and
right-arrow patterns as well as special left-arrow, center-out, and right-arrow patterns that comply with
CAC Title 13, Article 22 if used with the appropriate SignalMaster directional light bar in Tables 1 and 2 on
page 2.

The WARN function provides a non-directional flash pattern for use when a directional signal may not be
appropriate. One pattern can be selected from the ten patterns available, which include seven standard
patterns and three patterns that are compliant with CAC Title 13, Article 22. Some patterns are optimized
for LED products and flash too quickly for a halogen light bar. The default pattern is the classic SMC warn
pattern with four center light heads alternating with the two light heads on each end.
When standard directional signal operation is selected, the lamps illuminate sequentially in a sweeping
motion until all are illuminated, and then the pattern repeats. When Title 13 Mode is selected, the lamps
are extinguished more quickly than in standard mode. Title 13 Mode provides patterns that comply with
the 40 percent to 60 percent on-time and flash rate of 60 FPM to 120 FPM, which are requirements of
CAC Title 13, Article 22.
Although the controller operates at 12 Vdc to 24 Vdc, ensure that the SignalMaster light bar is of the
proper voltage for the electrical system of the vehicle. Do not operate a 12 V SignalMaster at 24 V or a
24 V SignalMaster at 12 V, or shortened lamp life will result.

DRILLING PRECAUTIONS: When drilling holes, check the area into which you are drilling to
ensure that you do not damage vehicle components. All drilled holes should be deburred and all
sharp edges should be smoothed. All wire routing going through drilled holes should be pro-
tected by a grommet or convolute/split-loom weaving.
3. Drill a hole sized for the installer-provided hardware to be used in step 4 at each drill position mark.
4. Secure the mounting bracket to the mounting surface with two installer-supplied, thread-forming,
1/4-inch screws or other hardware appropriate for the installation.
5. Before fastening the controller to the bracket, continue with the electrical connections as described
in the next sections.

Connecting Power to the Controller
HIGH-CURRENT ARCING: Do not connect this system to the vehicle battery until all other elec-
trical connections are completed and you have veried that no shorts exist. High current shorts
can cause hazardous sparks or burning wire, resulting in an electrical re.
The controller is equipped with a nine-position terminal block and an insulated spade connector.
Installer-supplied red and black wires of the proper gauge for the current and run length of the specific
installation are also required. For the recommended wire gauge, see Table 5 on page 5. The ground
wire should be sized to handle the total current used by the light bar and controller. Connect the light bar
using a red wire of the appropriate gauge to a fused positive power source. Installer-supplied 18 AWG
(minimum) red wire is required for the connection of the controller to the positive power source.
To make the power connections to the controller:
1. Strip 1/4 inch of insulation from the main ground wire and crimp the proper spade connector onto it.

BATTERY EXPLOSION: To avoid a battery explosion, always disconnect the negative battery
cable rst and reconnect it last. Avoid causing a spark when connecting near or to the battery.
The gases produced by a battery can cause a battery explosion that could result in vehicle
damage and serious injury.
CONNECTING THE RED AND BLACK WIRES: To avoid damage and ensure proper operation, the
red and black wires MUST be installed as shown in Figure 2 on page 6.
2. Connect the black ground wire to the lug as shown in Figure 2 on page 6. Securely tighten the
binding screw using a 1/4-inch flat tip screwdriver passing through the opening in the cover.
3. Route the ground wire through the firewall and toward the battery. Connect it to a good frame
ground near the battery. For gauge recommendations, see Table 5. In most vehicles, a wire from the
negative terminal of the battery is routed and attached to the screw at the body/frame at the fender.

Distance to
Battery 20 A Peak
5 ft 18 AWG
10 ft 16 AWG
20 ft 12 AWG
30 ft 12 AWG
40 ft 10 AWG
4. Connect the red wire from the nine-conductor cable of the SignalMaster™to the vehicle battery
through a 20A fuse holder that is located as close to the battery as possible. Do not install the
fuse until all other electrical connections have been made. To run between the fuse and the
SignalMaster, use a properly-sized red wire. For wire gauge recommendations, see Table 5.
5. Select a termination point for the 18 AWG red power wire from the controller. As applicable, route
the 18 AWG red wire toward the vehicle fuse block or through the firewall toward the battery. If the
controller power is to be connected to the battery, install a installer-supplied, in-line fuse in the
18AWG red wire as close to the battery as possible and terminate it as required. If the red wire is to
be terminated to the fuse block, select an appropriate fused circuit.
IMPORTANT: The termination point of the 18 AWG red wire from the controller 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 ignition switch must be in the run position to
operate the directional signal. When the wire is attached to the vehicle battery, the directional signal
can be operated at any time. To avoid draining the battery, Federal Signal recommends that the
power wire from the controller be terminated to a switched source.
NOTE: The controller draws 7 mA (0.007 A) in the o position when connected directly to the vehicle
battery.
6. Strip 1/4 inch of insulation from all of the wires that will enter nine-position the terminal block. Make
all of the required connections to the terminal block as described in the next section.
7. Connect the 18 AWG red wire to the position labeled on the terminal block for +12-24 Vdc.
