INSTALLATION AND OPERATING INSTRUCTIONS
SAFETY MESSAGE TO INSTALLERS OF SIREN SPEAKERS
WARNING
The lives of people depend on your proper installation and
servicing of Federal products. It is important to read and
follow all instructions shipped with the products. In addition,
listed below are some other important safety instructions and
precautions you should follow:
Before Installation
Qualifications
• To properly install an electronic siren: you must have a
good understanding of automotive electrical procedures
and systems, along with proficiency in the installation
and service of safety warning equipment. Always refer to
the vehicle's service manuals when performing
equipment installations on a vehicle.
Sound Hazards
• Your hearing and the hearing of others, in or close to
your emergency vehicle, could be damaged by loud
sounds. This can occur from short exposures to very loud
sounds, or from longer exposures to moderately loud
sounds. For hearing conservation guidance, refer to
federal, state, or local recommendations. OSHA
Standard 1910.95 offers guidance on “Permissible Noise
Exposure.”
• 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.
• Federal Signal siren amplifiers and speakers are
designed to work together as a system. Combining a
siren and speaker from different manufacturers may
reduce the warning effectiveness of the siren system and
may damage the components. You should verify or test
your combination to make sure the system works
together properly and meets federal, state and local
standards or guidelines.
During Installation
• DO NOT get metal shavings inside the product. Metal
shavings in the product can cause the system to fail. If
drilling must be done near the unit, place an ESD
approved cover over the unit to prevent metal shavings
from entering the unit. Inspect the unit after mounting
to be sure there are no shavings present in or near the
unit.
• DO NOT connect this system to the vehicle battery until
ALL other electrical connections are made, mounting of
all components is complete, and you have verified that
no shorts exist. If wiring is shorted to vehicle frame, high
current conductors can cause hazardous sparks resulting
in electrical fires or flying molten metal.
• Be sure the siren amplifier and speaker(s) in your
installation have compatible wattage ratings.
• In order for the electronic siren to function properly, the
ground connection must be made to the NEGATIVE
battery terminal.
FOR
MODEL MS100-01
COMPACT SPEAKER
• Sound output will be severely reduced if any objects are
in front of the speaker. If maximum sound output is
required for your application, you should ensure that the
front of the speaker is clear of any obstructions.
• Install the speaker(s) as far forward on the vehicle as
possible, in a location which provides maximum
signaling effectiveness and minimizes the sound
reaching the vehicle’s occupants. Refer to the National
Institute of Justice guide 500-00 for further information.
• 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 air
bag 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. Insure 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 air bag.
• 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.
After Installation
• After installation, test the siren system 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 and/or reinstalling the product.
Failure to follow all safety precautions and instructions may
result in property damage, serious injury, or death to you or others.
A. GENERAL.
NOTE
The Model MS100 is a compact speaker designed to
be mounted using the supplied bracket.
If the MS100 is installed using another mounting
system, the safety and effectiveness of the installation
must be carefully evaluated.
IMPORTANT
This speaker complies with SAE J1849 EVS3
and CCR Title 13 Class A requirements when
used with Federal Signal Corporation electronic
sirens.
B. UNPACKING.
After unpacking the unit, inspect it for damage that
may have occurred in transit. If the unit has been
damaged, do not attempt to install or operate it. File a
claim immediately with the carrier, stating the extent of

D. INSTALLATION.
Because of the variety of vehicles and possible
mounting arrangements, installation details and
mounting bracket fabrication must be determined by the installer.
a. Select an appropriate mounting location
which provides both adequate support and sufficient
clearance for the speaker assembly. In addition , the
mounting location should provide maximum signaling
effectiveness while minimizing the sound reaching the
vehicle’s occupants.
b. Attach the supplied bracket to the speaker
using the 5/16-18 x 3/4" bolts and split lockwashers as
shown in figure 1. Do not tighten the bolts at this time.
WARNING
To avoid reduction of sound output and damage
to the speaker, ensure that the speaker is
mounted with the wires exiting from the right
side of the speaker when looking at it from the
front.
c. If necessary, remove the bracket from the
speaker. Using the bracket as a template, scribe four
drill positioning marks at the selected mounting location.
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.
NOTE
The installation procedure in paragraph D.1.
may not apply to all vehicles. Some vehicle
specific instructions are included below. Before
proceeding, check to see if instructions for your
vehicle are included. Otherwise, use the procedure in paragraph D.1.
1. General.
The supplied bracket is designed for mounting
directly on a surface which has been determined to be
suitable for speaker installation. In addition, it may be
used to install the speaker on an adapter bracket
fabricated by the installer.
The bracket has two sets of speaker mounting
holes. Use the outer pair of holes when mounting on a
horizontal surface. Use the inner pair of holes when
mounting on a vertical surface. When using the inner
pair of holes (vertical surface mounting), space restrictions may require removal of the excess bracket material that protrudes in front of the speaker.
d. Drill 3/16" mounting holes at the position
marks.
NOTE
Some mounting arrangements may require
installing the bracket on the mounting surface
before securing the speaker to the bracket.
e. Secure the bracket, or assembled unit, unit
to the mounting surface using the 1/4" x 5/8" type B
screws and 1/4" lockwashers as shown in figure 1.
Position the front of the speaker perpendicular to a
horizontal mounting surface or parallel to a vertical
mounting surface, and secure the speaker to the bracket
with the 5/16-18 x 3/4" bolts.
f. Connect the two leads from the speaker to
the electronic siren’s speaker cable. When two speakers
are used, it is necessary to connect them in phase. This
can be accomplished by connecting the two “red” speaker
leads to one lead of the siren’s speaker cable, and the
two “black” speaker leads to the other siren speaker
cable lead. Refer to the instructions packed with the
electronic siren for additional details.
