Safety Messages to Installers of Sound/Light Systems
People’s lives depend on your proper installation and servicing of Federal Signal

product. Listed below are some other important safety instructions and precautions
you should follow:
Before Installation
Qualifications

the installation and service of safety warning equipment. Always refer to
the vehicle’s service manuals when performing equipment installations on a

• 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

may damage the components. You should verify or test your combination to
