Code 3 C3100 Series Speaker - Manual (Page 3)

Selecting a Mounting
Location: The mounting
location should not only be
as flat as possible but also,
allow the siren to project its
tone parallel to the road.
For detailed information on
mounting locations for
certain specific vehicles,
see the following pages.
Installation: Position the
bracket onto the desired
mounting area and mark
the centers of the 4
mounting holes using the bracket as a template.
Now in the center of each of the 4 holes you marked, drill a 1/8-inch pilot
hole into the mounting surface for each of the 4 screws then enlarge the
pilot holes with a 9/32-inch drill. If you can get access to the other side of
the mounting area, and it is not too thick, you may want to substitute the 4
mounting screws with nuts, bolts and washers (customer supplied) of
comparable strength and size.

absolutely essential that the speaker be mounted so that the wires
exit at the the bottom (toward the ground). Improper mounting will
cause damage to your C3100 Speaker and void the warranty
