Safety Message to Installers of Sound/Light Equipment
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. 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, ensure that both sides of the surface are clear of anything that
could be damaged. All drilled holes should be deburred and all sharp edges should be smoothed.
All wires going through drilled holes should be protected by a grommet or convolute/split-loom
tubing. Additionally, all exterior drilled holes must be sealed with Motorcraft seam sealer T-A-2-B or
equivalent to prevent the potential exposure to carbon monoxide or other potentially harmful fumes.
Failure to observe this warning could cause serious injury or death.
• 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.
• 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.
Overview
The SignalMaster
®
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.
