mounting in some cases will result in a dramatic reduction in performance. To minimize this
reduction, mount the speaker so the sound emitted is projected directly forward and obstruction
by vehicle components such as hoses, brackets, grille, etc. is minimized.
Electromechanical sirens and electronic siren speakers should be mounted as far from the
occupants as possible using acoustically insulated compartments and isolation mountings to
minimize the transmission of sound into the vehicle. It may be helpful to mount the device on
the front bumper, engine cowl or fender; heavily insulate the passenger compartment; and
operate the siren only with the windows closed.
Each of these approaches may cause significant operational problems, including loss of siren
performance from road slush, increased likelihood of damage to the siren in minor collisions,
and the inability to hear the sirens on other emergency vehicles.
APPROPRIATE TRAINING OF VEHICLE OPERATORS IS RECOMMENDED TO ALERT
THEM TO THESE PROBLEMS AND MINIMIZE THE EFFECT OF THESE PROBLEMS
DURING OPERATIONS.
All devices should be mounted in accordance with the manufacturer's instructions and
securely fastened to vehicle elements of sufficient strength to withstand the forces applied to
the device. Ease of operation and convenience to the operator should be the prime
consideration when mounting the siren and controls. Adjust the mounting angle to allow
!
maximum operator visibility. Do not mount the Control Head Module in a location that will
obstruct the drivers view. Mount the microphone clip in a convenient location to allow the
WARNING!
operator easy access. Devices should be mounted only in locations that conform to their
SAE identification code as described in SAE Standard J1849. For example, electronics
designed for interior mounting should not be placed underhood, etc.
Controls should be placed within convenient reach* of the driver or if intended for two
person operation the driver and/or passenger. In some vehicles, multiple control switches
and/or using methods such as "horn ring transfer" which utilizes the vehicle horn switch to
toggle between siren tones may be necessary for convenient operation from two positions.
*Convenient reach is defined as the ability of the operator of the siren systems to manipulate
the controls from his normal driving/riding position without excessive movement away from
the seat back of loss of eve contact with the roadway.
IMPORTANT WARNINGS TO USERS OF SIRENS: "Wail" and "Yelp" tones are in some
cases (such as in the state of California) the only recognized siren tones for calling for
!
the right of way. Ancillary tones such as "Air Horn", "Hi-Lo", "Hyperyelp", and
"Hyperlo" in some cases do not provide as high a sound pressure level. It is

recommended that these tones be
the presence of multiple emergency vehicles or to momentarily shift from the primary
tone as an indication of the imminent presence of an emergency vehicle.
Any electronic device may create or be affected by electromagnetic interference.
!
After installation of any electronic device, operate all equipment simultaneously to
insure that operation is free of interference.
