Safety Message to Installers of Federal Signal Light and Sound Systems

The lives of people depend on your safe installation of Federal Signal products. It is important to

read and follow all instructions shipped with the products. 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 electri-

cal procedures and systems along with proficiency in the installation and service of safety warning

equipment.

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 and 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, which may, in certain situations, cause perma-

nent hearing loss. You should minimize your exposure times and wear suitable hearing protection.

During Installation

• DO NOT connect this system to the vehicle battery until ALL other electrical connections are

made, mounting of all components is complete, and you have verified that no shorts exist.

• Be sure the siren amplifier and speaker in your installation have compatible wattage ratings.
• For this electronic siren to function properly, the ground connection must be made to the NEGA-

TIVE battery terminal.

• Sound output will be severely reduced if any objects are in front of the speaker. If maximum sound

output is required for your application, you should ensure that the front of the speaker is clear of

any obstructions.

• Install the speaker in a location which provides maximum signaling effectiveness and minimizes

the sound reaching the vehicle’s occupants.

• Never attempt to install aftermarket equipment which connects to the vehicle wiring, without re-

viewing a vehicle wiring diagram - available from the manufacturer. Insure that your installation

will not affect vehicle operation or mandated safety functions or circuits.

• DO NOT install equipment, route wiring or cord in the deployment path of an airbag.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to

be recalibrated for proper airbag deployment.

• Locate the siren so the vehicle controls can be operated safely.
• When drilling into a vehicle structure, be sure that both sides of the surface are clear of anything

that could be damaged.

• If wiring is shorted to vehicle frame, high current conductors can cause hazardous sparks resulting

in electrical fires or flying molten metal.
