CHAPTER 8
Safety Messages to Personnel Servicing Federal Signal
Electronic Sirens
The 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. |In addition, 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 pad.
•
To properly service an electronic siren or control pad, 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. 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.
