Polaris MS4000 Service And Owner's Manual page 110

After the installation, test the siren system to ensure that it is operating properly. Also test all
vehicle functions, including horn operation, vehicle safety functions, and vehicle lighting systems
to insure proper operation. Ensure that the installation has not affected the vehicle operation or
changed any vehicle safety functions or circuits.
Do not test the sound and light system of the vehicle while driving. Operating the vehicle
warning systems may pose a hazard to the operator and other drivers if the systems do not
function as expected. Test the vehicle only in a controlled environment.
Safety Message To Personnel Operating Federal Signal
Siren Speakers
People's lives depend on your safe operation 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:
Qualifications
• To properly use an electronic siren and speaker(s), you must have a good understanding
of general vehicle operation, a high proficiency in the use of safety warning equipment,
and thorough knowledge of state and federal UNIFORM TRAFFIC CODES.
Sound Hazard
• 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, roll up your windows and
wear hearing protection. Do not sound the siren indoors or in enclosed areas where you
and others will be exposed to the sound. Only use the siren for emergency response
situations.
Sound Limitations
• Before using the vehicle, check to see if the siren speakers are concealed from view. If
the siren speaker is not in clear view on the front of the vehicle, use extra caution when
operating the vehicle. A concealed siren speaker installation is less effective at warning
others.
• Maximum sound output will be severely reduced if any objects are in front of the speaker.
If your installation has obstructions in front of the speaker, drive even more cautiously.
• Frequently inspect the speaker to ensure that it is clear of any obstruction, such as mud
or snow, which will reduce maximum sound output.
Signaling Limitations
• Be aware that the use of your visual and audible signaling devices does not give you
the right to force your way through traffic. Your emergency lights, siren, and actions are
REQUESTING the right-of-way.
