Safety Messages to Installers of Federal Signal 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.
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.
• 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 federal, state and local standards or guidelines.
During Installation
• Do NOT get metal shavings inside the product. Metal shavings in the product
can cause the system to fail. If drilling must be done near the unit, place an ESD-
approved cover over the unit to prevent metal shavings from entering the unit.
Inspect the unit after mounting to ensure that there are no shavings present in or
near the unit.
