• Mounting the speakers behind the grille
will reduce the sound output and warning
effectiveness of the siren system. Before
mounting speakers behind the grille, make sure
the vehicle operators are trained and understand
that this type of installation is less effective for
warning others.
• Sound propagation and warning effectiveness
will be severely reduced if the speaker is not
facing forward. Carefully follow the installation
instructions and always install the speaker with
the projector facing forward.
• Do NOT install the speaker(s) or route the
speaker wires where they may interfere with the
operation of airbag sensors.
• Installation of two speakers requires wiring
speakers in phase.
• Never attempt to install aftermarket equipment,
which connects to the vehicle wiring, without
reviewing a vehicle wiring diagram available
from the vehicle manufacturer. Ensure that your
installation will not affect vehicle operation
and safety functions or circuits. Always check
vehicle for proper operation after installation.
• Do NOT install equipment or route wiring or
cord in the deployment path of an airbag.
• If a vehicle seat is temporarily removed, verify
with the vehicle manufacturer if the seat needs
to be recalibrated for proper airbag deployment.
• Locate the control head so the vehicle, controls,
and microphone can be operated safely.
• When drilling into a vehicle structure, be
sure 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.
After Installation
• After installation, test the siren and light system
to ensure that it is operating properly.
• Test all vehicle functions, including horn
operation, vehicle safety functions and vehicle
light systems, to ensure proper operation.
Ensure that installation has not affected vehicle
operation or changed any vehicle safety
function or circuit.
• After testing is complete, provide a copy of
these instructions to the instructional staff and
all operating personnel.
• File these instructions in a safe place and refer
to them when maintaining or reinstalling the
product.
Failure to follow all safety precautions and
instructions may result in property damage, serious
injury, or death.
