SAFETY MESSAGETO 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.
• 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 negative
battery terminal. 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
CONTROL 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 SML6-2SML1F and
SML6-2SML1F30 are six-lamp directional light assemblies
with two additional outer lamps controlled by a flasher PCB
assembly. The flasher assembly can be activated by either
+12Vdc or ground. Lens colors available are: amber (standard),
red, blue, and clear.
WARNING
These lights are intended for secondary warning
only. They are not intended for use as a primary
warning system.
II. INSTALLATION.
A. SignalMaster Light Assemblies.
Install the light assembly as described in the
mounting kit instructions, and route the cable near the
eventual location of the control unit.
CAUTION
Install the control unit in an adequately ventilated
area. Never install near heater ducts.
B. Control Unit.
NOTE
Before selecting a mounting location for the control
unit, it is necessary to plan wiring and cable routing.
Use a Federal Signal SMC16 or SMC56 control unit.
Install the control unit and complete the wiring as described in
the control unit instructions.
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.
C. Flasher Connections.
1. SMC56 Control Unit (ground activation via AUX
switch).
See figure 1. Connect the ten-conductor cable’s
pink lead to the fused +12Vdc (+BAT) position on the seven-
position connector. Connect the blue lead to ground. Using a
one-ampere fuse, connect the white wire to the seven-position
connector’s AUX OUT position. Connect the remaining wires as
shown in figure 1. The flasher will operate when the control
unit’s AUX switch is activated.

2. SMC16 Control Unit (+12Vdc activation via
user-supplied switch).
See figure 2. Connect the ten-conductor cable’s
blue lead to ground. Connect the white lead to ground. Connect
the pink lead to one side of a user-supplied switch (one-ampere
minimum). Connect the other side of the switch to +12Vdc. The
flasher will operate upon activation of the user-supplied
switch.
3. SMC16 Control Unit (ground activation via
user-supplied switch).
See figure 3. Connect the ten-conductor cable’s
blue lead to ground. Connect the pink lead to +12Vdc. Connect
the white lead to one side of a user-supplied switch (one-
ampere minimum). Connect the other side of the switch to
ground. The flasher will operate upon activation of the user-
supplied switch.
III. MAINTENANCE.
A. General.
WARNING
Crazing (cracking) of lenses will cause reduced
effectiveness 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
accomplished 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, automo-
tive paste cleaner/wax and a soft cloth.
B. Lamp Replacement.
WARNING
A serious injury may result if lamp is touched when
hot. Always allow lamp to cool before removing.
Halogen lamps are pressurized and if broken can
result in flying glass. Always wear gloves and eye
protection when handling the lamps.
CAUTION
Use of higher wattage lamps can result in damage to
the colored lenses.
1. See figure 4. Remove and retain the two screws
which secure the lens. Carefully pull the lens straight away
from the light assembly.
CAUTION
Service life of lamp will be shortened if glass is
touched. If glass has been handled, clean with a
grease solvent.
2. Remove the defective lamp by carefully pulling it
out of the socket. Install a new lamp by aligning the pins on
the lamp base with the holes in the socket, and carefully
pushing the lamp into the socket.
3. Replace the lens using the previously removed
screws.
