SAFETY MESSAGE TO PERSONNEL SERVICING
GALLS SIREN SPEAKERS
The lives of people depend on your proper
servicing of Galls products. It is important to
read and follow all instructions shipped with
the products. In addition, listed below are
some other safety instructions and precau-
tions 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.
•
Galls 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 guidelines.
Failure to follow all safety precautions and
instructions may result in property damage, serious
injury, or death to you or others.
