2.
Using the mounting holes on the amplifier as a template, scribe four drill position
marks at the mounting location.
DRILLING PRECAUTIONS: Before drilling holes, check the area into which
you plan to drill to ensure that you do not damage vehicle components. All
drilled holes should be deburred and all sharp edges should be smoothed.
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.

The mounting hardware supplied in the siren accessory kit gives you 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-inch holes at the drill position marks.
Drill 9/32-inch holes at the position marks if you are using the 1/4-20 cap screws,
lockwashers and nuts.
4.
Secure the amplifier to the mounting surface using the mounting hardware,
including lockwashers.
Installing the Control Head
AIRBAG DEPLOYMENT: Do not install equipment or route wiring in the
deployment path of an airbag. Failure to observe this warning will reduce the
effectiveness of the airbag or potentially dislodge the equipment, causing
serious injury or death.
SEAT REMOVAL PRECAUTION: If a vehicle seat is temporarily removed, verify
with the vehicle manufacturer if the seat needs to be recalibrated for proper
airbag deployment. Failure to follow this warning cause serious injury or
death.
The control head is designed to be flush mounted in any relatively flat surface.
To install the control head:
1.
Select a location for the control head on the mounting surface that does not impair
drivers’ ability to safely drive the vehicle as they operate 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.
