I. GENERAL.

The Federal SignalMaster™ Model SMC14 is an

economical, low profile, solid state, directional light control

that is designed to operate with two Federal Signal four-

lamp directional light assemblies (Model SML4-30). 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. In addition,

an alternating flash pattern produces a warning signal for

use when a directional signal may not be appropriate.

When a directional signal is selected, the lamps are

individually illuminated in a sequential sweeping motion

until all eight lamps are illuminated.

These lights are intended for secondary warn-

ing only. They are not intended for use as a

primary warning system.

A. SignalMaster Light Assembly (Model SML4-30).

Install the light assembly as described in the

instructions packed with the 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 equip-

ment 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.

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.

The control unit is supplied with a six-position

connector and a eleven-position terminal block to perform

the electrical installation. User-supplied, 14-gauge red and

black wires are required for the (+) BAT and (-) GND

connections on the six-position connector. User-supplied,

18-gauge red and green wires are required for the (+) BAT/

IGN and CASE GROUND connections on the six-position

connector. 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 in the six-

position connector as shown in figure 3.

a. Strip 1/4" of insulation off of each wire.

See figure 3. Use small blade screwdriver to depress spring

in connector, insert proper wire and remove screwdriver to

release spring.

b. Connect the red and black 14-gauge wires

to the connector as shown in figure 3.

See figure 1. The supplied mounting bracket

allows the control unit to be mounted in a variety of

positions. To install 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 that the cable is

30-feet long. 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.

Figure 1. Figure 2.

Figure 3.

-3-

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 and green wires

to the connector as shown in figure 3.

IMPORTANT

The 18-gauge red wire’s termination point deter-

mines 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 bat-

tery, the directional signal can be operated at any

time. Note that the unit draws no current when in

the “off” position.

e. Select the desired termination point. As

applicable, route the 18-gauge red wire toward the vehicle

fuse block or through the firewall toward the battery.

Install a user-supplied, 1-ampere, in-line fuse in the 18-

gauge red wire as close to the power source as possible and

terminate as required.

f. Route the 18-gauge green wire to a known

good chassis ground near the SMC14 control. To provide a

good ground connection, scrape any painted surface to bare

metal and terminate as required.

g. Ensure that positions 5 and 6 of the six-

position connector are not used (see figure 2).

h. Plug the six-position connector into the

mating connector on the control unit, and apply pressure

until it locks into place.

2. SignalMaster Cable Connections.

a. Route the SignalMaster cable towards the

control unit, while being careful not to scrape the wires on

any sharp edges.

b. If necessary, cut the cable to the appropri-

ate length.

c. Connect the both sets of SML4 wires to

the terminal block as shown in figure 2. Positions 9 and 10

are not used. Ensure that the driver and passenger wire

sets are connected to the terminal block EXACTLY as

shown in figure 2.

D. Inspection and Final Installation.

1. Ensure that there are no loose wire strands or

other bare wires which may cause a short circuit. Also, all

wires must be protected from any sharp edges which could

eventually cut through the insulation.

2. Connect the remaining end of 14-gauge red

wire from the six position connector to the (+) positive

terminal of the battery with an in-line, user-supplied

fuseholder and 25A fuse. Locate the fuse as near the

battery as possible to protect the entire length of wire.

3. Read and understand paragraph IV OPERA-

TION, and test for proper operation of all functions.

4. Secure the mounting bracket to the control

unit with the 1/4-20 hex head, thread forming screws and

1/4" external tooth lock washers (see figure 1).

IV. OPERATION.

SAFETY MESSAGE TO OPERATORS

Peoples’ lives depend on your safe use of our products.
