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 installa-

tion and use of safety warning equipment.

• 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 separate

ground connection must be made. If practical, it

should be connected to the fusible link at the front

fender between the negative (-) battery terminal and

chassis ground. At a minimum, it may 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 CON-

TROL can be operated safely under all driving

conditions.

• Do not attempt to activate or deactivate light control

while driving in a hazardous situation.

• 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 SignalMaster™ Models SM518A-NFPA and

SM428A-NFPA are economical, low wattage, directional light

assemblies that are designed for use in a flashing mode. Lens

colors available are: amber (standard), red, blue, green, and clear.

These models provide three distinctive and prioritized

lighting patterns. The highest priority pattern is the left arrow

and right arrow directional signal. When this signal is selected,

the lamps are individually illuminated in a sequential sweeping

motion until all eight lamps are illuminated. The lower priority

pattern is the warn signal. When this signal is selected, an

alternating flash of the four outside lamps with the two inside

lamps occurs. This signal may be used when a directional signal is

not appropriate. The lowest priority pattern is the low power warn

signal. When this signal is selected, the two outside lamps on each

side of the light assembly will alternately flash.

power source. Ensure that the power source is capable of supplying

an additional 25-amperes.

b. Connect the black wire to a known good chassis

ground. This connection must be capable of supplying 25-amperes.

c. Do not connect the red wire to the positive (+)

power source terminal at this time.

2. Control Head Connections.

a. Wrap the control cable’s stripped wire ends

with tape and route the cable to the control head mounting

location.

b. See figure 2. Crimp five 1/4" straight terminals

on the cable wire ends and jumper wire combination.

c. Connect the terminals on the switch as shown

in figure 2.

3. Illuminated Power Switch.

CAUTION

Improper wiring of the illuminated switch feature will

result in printed circuit board damage. Ensure that the

chassis ground lead is connected to the gold (pin #3)

terminal and that the unterminated end of the lead is

connected to a known good chassis ground.

a. See figure 2. Connect the right angle terminal

on the switch bracket ground lead to the gold (pin #3) terminal of

the on-off switch.

b. Route the unterminated end of the ground lead

to a known good chassis ground. Cut the lead to length and crimp

the supplied ring terminal on the lead.

NOTE

If necessary, additional 18-gauge wire may be spliced to

the ground lead.

c. Secure the lead to the chassis ground with a

user-supplied screw.

4. Low Power Warn Connections.

IV. OPERATION.

SAFETY MESSAGE TO OPERATORS

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

below are some important safety instructions and precautions you

should follow:

• Although your warning system is operating properly,

it may not be completely effective. People may not

see or heed your warning signal. You must recognize

this fact and continue driving cautiously.

• Also, situations may occur which obstruct your

warning signal when natural or man-made objects

are between your vehicle and others, such as: raising

your hood or trunk lid. If these situations occur, be

especially careful.

• At the start of your shift, you should ensure that the

light is securely attached and all lamps are operat-

ing properly.

• If a selected function does not perform properly or if

any of the lamps remain illuminated when the

control is off, disconnect the power connector from

the control unit and contact the nearest service

center.

Failure to follow these safety precautions may result in

property damage, serious injury, or death to you, to passengers, or

to others.

flashing pattern, instructing traffic to move left.

2. CENTER Position.

In this position, an alternating pattern is produced.

The four middle lights activate alternately with the two outside

lights on each side.

3. RIGHT Position.

In this position, the light produces a right arrow

flashing pattern, instructing traffic to move right.

C. Low Power Warn.

This pattern alternately flashes both end lamps on each

side of the light assembly.

To activate the low power warn pattern, the vehicle

ignition switch must be “on”, the SignalMaster’s on/off switch must

be “off”, and the vehicle parking brake must be applied.

CAUTION

Damage to the directional light assembly will occur if this

vehicle is jump-started when the light is “on”. Ensure

that the light is switched “off” before jump-starting this

vehicle.

V. MAINTENANCE.

A. General.

WARNING

Crazing (cracking) of lenses will cause reduced effective-

ness of the light. Do not use cleaning agents (which will

cause crazing) such as strong detergents, solvents, or

petroleum products. If crazing of lenses does occur,

reliability of light for emergency signalling purposes may

be reduced until lenses are replaced.

Ordinary cleaning of the plastic lenses can be accom-

plished by using mild soap and a soft rag. Should fine scratches or

a haze appear on a lens, they can ordinarily be removed with a

non-abrasive, high quality, one-step, automotive paste cleaner/wax

and a soft cloth.

B. Lamp Replacement.

CAUTION

Use of higher wattage lamps can result in damage to the

colored lenses.

1. See figure 3. Remove and retain the two screws

which secure the lens. Carefully pull the lens straight away from

the light assembly.
