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 operator easy access.
Devices should be mounted only in locations that conform to their SAE identification code as
described in SAE Standard J 1849. 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 or loss of eye contact with the roadway.
The user should install a fuse sized to approximately 125% of the maximum Amp capacity in the
supply line to protect against short circuits. For example, a 30 Amp fuse should carry a maximum
of 24 Amps. DO NOT USE 1/4" DIAMETER GLASS FUSES AS THEY ARE NOT SUITABLE FOR
CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit breakers are very sensitive to high
temperatures and will "false trip" when mounted in hot environments or operated close to their
capacity.
CONNECTION OF A 58 WATT SPEAKER TO THE 100 WATT TERMINAL WILL CAUSE THE
SPEAKER TO BURN OUT, AND WILL VOID THE SPEAKER WARRANTY!
The sound projecting opening should be pointed forward, parallel to the ground, and not obstructed
or muffled by structural components of the vehicle. Concealed or under-hood mountings 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.
