SAFETY MESSAGE TO PERSONNEL SERVICING
FEDERAL SIGNAL ELECTRONIC SIRENS
WARNING
The lives of people depend on your
proper servicing of Federal products. It
is important to read and follow all in-
structions 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 elec-
tronic technician.
•
Your hearing and the hearing of others, in or
close to your emergency vehicle, could be dam-
aged 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.
•
DO NOT connect this system to the positive
terminal of the battery until servicing is com-
plete, and you have verified that there are no
short circuits to ground.
•
In order for the electronic siren to function
properly, 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 effec-
tiveness 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 guidelines.
Failure to follow all safety precautions and
instructions may result in property damage,
serious injury, or death to you or others.
