SAFETY MESSAGE TO PERSONNEL SERVICING
FEDERAL SIGNAL SIREN SPEAKERS
WARNING
The lives of people depend on your proper servicing
of Federal products. It is important to read and
follow all instructions shipped with the products.
In addition, listed below are some other safety
instructions and precautions you should follow:
•
Read and understand all instructions in this
manual before servicing the electronic siren or
speaker.
•
To properly service an electronic siren or speaker:
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 service on a
vehicle.
•
Electronic circuit and speaker repairs must be
performed by a qualified and competent electronic
technician.
•
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 recommen-
dations. 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.
•
DO NOT connect this system to the positive
terminal of the battery until servicing is complete,
and you have verified that there are no short
circuits to ground.
•
In order for the electronic siren to function prop-
erly, the ground connection must be made to the
NEGATIVE battery terminal.
•
After repair, test the electronic siren and speaker
system to ensure that it is operating properly.
•
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
both federal, state and local standards or guide-
lines.
Failure to follow all safety precautions and instruc-
tions may result in property damage, serious injury, or
death to you or others.
Opening the unit will void the warranty. This speaker
has no field serviceable parts. The factory can and will
service your speaker. If you are experiencing problems with
the speaker, send it to:
