INSTALLATION.
The Model BP350S is designed specifically for mounting in pre-drilled
holes in the E350 bumper. If the speakers are installed using other
mounting arrangements, the safety and effectiveness of the installation
must be carefully evaluated.
To install the Model BP350S, proceed as follows:
1.
Cut the adhesive-backed air dam templates (one driver side and
one passenger side) from the supplied template sheet. Be sure to follow the
outside edge of the lines when cutting out the templates. See figure 1.
2.
To attach the templates to the underside of the air dam, remove
the backing from a template. See figure 2. Align the back side of the
template with the back side of the air dam, and adhere the template to the
air dam’s underside.
3.
See figures 2 and 3. Cut vertically along the template lines up to
the bumper. Make an initial horizontal cut between the two vertical cuts as
close to the bumper as possible. Remove the cut portion of the air dam.
4.
See figure 4. Using the vertical cuts as a guide, mark a cut line
on the air dam 3-inches from the rear edge of the bumper as shown. Cut and
remove the air dam in the marked area.
5.
Install the 1/4-20 and 5/16-18 mounting bolts in the speaker
projector using flat washers and bolt retainers as shown in figure 5.
WARNING
To avoid reduction of sound output and damage to the speakers,
ensure that the speakers are mounted with the drain hole facing
downward as indicated by the label on the projector.
6.
See figure 5. Position the speaker in the opening cut in the air
dam and secure using flat washers, split lockwashers and nuts.
CAUTION
Before drilling holes in ANY part of a vehicle, be sure that both
sides of the mounting surface are clear of parts that could be
damaged; such as brake lines, fuel lines, electrical wiring or other
vital parts.
7.
Using the slot in the speaker tab as a guide, scribe a drill
position mark on the air dam. Drill a
3/16" hole at the drill position mark.
8.
Secure the air dam to the speaker using a #8-32 screw, 0.88"
O.D. washer, lockwasher and nut as shown in figure 6.
9.
If installing two speakers, repeat steps D.2. through D.8. on the
vehicle's other side.
10.
Connect the two leads from the speaker to the electronic siren’s
speaker cable. If two speakers are installed, it is necessary to connect the
speakers in-phase. This is accomplished by connecting the two speaker leads
marked “1” to the same lead of the siren’s speaker cable, and the two
speaker leads marked “2” to the other lead of the siren’s speaker cable. Refer
to the instructions packed with the electronic siren for additional details.
WARNING
All effective sirens and horns produce loud sounds (120 dB) that
may cause permanent hearing loss. Always minimize your
exposure to siren sound and wear hearing protection. Do not
sound the siren indoors or in enclosed areas where you and others
will be exposed to the sound.
11.
Test the system for proper operation.
