Safety Messages to Personnel Servicing Federal Electronic Sirens
People’s lives depend on your proper servicing of Federal Signal products. It is
important to read and follow all instructions shipped with the products. 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 control head.
• To properly service an electronic siren or control head, 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 service manuals when performing service on a vehicle.
• Electronic repairs must be performed by a qualified and competent electronics
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 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 complete and you have verified that there are no short circuits to
ground.
• 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 effectiveness of the siren system and may damage
the components. 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.
