Federal Signal Corporation STREETHAWK FHL4856R Wiring And Maintenance Instructions

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 this
product and the related add-on 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 profi-
ciency 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. Remove all
burrs from drilled holes. To prevent electrical
shorts, grommet all drilled holes through
which wiring passes.
• A light system is a high current device. In
order for it 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 is to be used.
• This product may contain high intensity LED
devices. To prevent eye damage, DO NOT stare
into the light beam at close range.
• High voltages are present inside the strobe
light equipped models during and after
operation. Ensure that power is disconnected
and wait at least ten minutes before removing
the dome.
• Locate light system controls so the VEHICLE
and CONTROLS can be operated safely under
all driving conditions.
• 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 instruc-
tions may result in property damage, serious injury, or
death to you or others.
I. GENERAL.
The light assembly comes from the factory with ten (10)
stationary light lenses, gaskets, and mounting hardware in kit
form. This enables the user to choose and install the color
combination that best suits the application.
WIRING AND MAINTENANCE
FEDERAL ALL LIGHT STREETHAWK® LIGHT ASSEMBLY
WARNING
FOR
Using a lens colored differently than an LED will
greatly reduce the light output, thereby reducing
the effectiveness of the light for emergency
signaling purposes. Either use a clear lens or
match the color of the lens with the LED.
Federal recommends that lenses be installed prior to
mounting the light assembly on the vehicle. To install a lens in
any position, proceed as follows (see figure 5):
A. Install gasket on rim of lens.
B. Insert lens and gasket into lens opening. Secure with two
#6 screws. Tighten to 10-15 in./lbs. of torque.
II. ELECTRICAL WIRING.
A. General.
The Light Assembly is completely wired at the factory
and does not require any additional internal wiring. (If desired, to
allow Intelli-Flash Mode 2, connect the wht/red Intelli-Flash wire
to an unused power cable wire or a user-supplied wire.) The cable
connected to the Light Assembly contains all the conductors
necessary for proper control of all basic and optional functions (see
figure 1).
To prevent personal injury and/or damage to
vehicle components, in the event of a short-circuit
in the power cable, install a fuse in each incoming
cable conductor.
Figures 6 and 7 illustrate the external/internal Light
Assembly wiring by function. Using figures 1, 6, and 7 as a guide,
make the appropriate electrical connections shown in Table 1. Be
sure to use fuses (current ratings shown in the applicable diagram
in figures 6 and 7), wire and switches with adequate current
capacity for each function.
Any of the light assembly functions can be activated by
applying 12VDC to the appropriate control line. The
heavy black lead (-) must be connected to vehicle ground,
to perform a function check.
B. Programming the Intelli-Flash (see figure 7).
To operate the flasher in Mode 1, close SW1. To operate
the flasher in Mode 2, close SW1 and SW2.
Turn on the flasher in Mode 1. Short across the program-
ming pins until the desired pattern is running. Allow the pattern
to run for at least 15-seconds to program Mode 1.
Turn on the flasher in Mode 2. Short across the program-
ming pins until the desired pattern is running. Allow the pattern
to run for at least 15-seconds to program Mode 2.
