Safety Messages to Installers of Sound/Light Systems
People's lives depend on your proper installation and servicing of Federal Signal products. It is
important to read and follow all instructions shipped with this product. 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.
