3-1. UNPACKING
After unpacking the Model PA4000, examine it
for damage that may have occurred in transit. If
the equipment has been damaged, file a claim
immediately with the carrier stating the extent
of the damage. Carefully check all envelopes,
shipping labels and tags before removing or
destroying them.
3-2. AMPLIFIER INSTALLATION
The Amplifier is NOT waterproof. It must be
mounted in a location which is sheltered from
falling rain, snow, standing water, etc. It must
also be installed in an adequately ventilated area.
Never install near heater ducts. Do not mount the
Amplifier under the vehicle’s hood.
1. Select a suitable mounting location for the
Amplifier. Some possible mounting locations
are: in the equipment cabinet, under the front
seat, or in the trunk (under the rear deck,
near the rear seat speakers, if vehicle is so
equipped). Keep in mind that the control cable
is 15 feet long.
2. Using the mounting holes on the amplifier as a
template, scribe four drill position marks at the
mounting location.
DRILLING PRECAUTIONS: 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 exposureto
carbon monoxide or other potentially harmful
fumes. Failure to observe this warning could cause
serious injury or death.
c. The mounting hardware supplied in the
siren accessory kit provides the siren
user with a choice of mounting hardware;
thread-forming screws with lockwashers
or 1/4-20 cap screws with lockwashers and
hex nuts. Consequently, the holes drilled in
the mounting surface must be appropriate
for the mounting screws selected. If the
thread-forming screws are to be used, drill
3/16" holes at the drill position marks.
Drill 9/32" holes at the position marks if
the 1/4-20 cap screws, lockwashers and
nuts will be used.
d. Secure the Amplifier to the mounting
surface using the mounting hardware,
including lockwashers.
3-3. CONTROL HEAD INSTALLATION
When installing equipment inside air bag equipped
vehicles, the installer MUST ensure that the
equipment is installed ONLY in areas recommended
by the vehicle manufacturer.
Failure to observe this warning will reduce the
effectiveness of the air bag, damage the air bag, or
potentially damage or dislodge the equipment,
causing serious injury or death to
you or others.
The Control Head is designed to be flush mounted
in any relatively flat surface. To install, proceed as
follows:
1. Select a location for the Control Head on the
mounting surface that does not impair the
drivers’ ability to safely drive the vehicle as he
operates the siren. The selected location should
afford good visibility and free accessibility to
the Control Head controls.
2. Place the mounting template, supplied in the
accessory kit, over the selected mounting
location. Scribe a mark for each of the four
mounting holes. Also, scribe a cut mark along
the heavy dark line on the template.
DRILLING PRECAUTIONS: 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 exposureto
carbon monoxide or other potentially harmful
fumes. Failure to observe this warning could cause
serious injury or death.
