Introduction
The LFAMP is intended for use as a Secondary Acoustical Warning Device for use with your standard Code 3 
siren. The LFAMP generates a penetrating low frequency tone which, when used in conjunction with your
standard Code 3
 siren, may help to alert others to the approach of an emergency vehicle. The LFAMP
should be used only in conjunction with the normal operation of your standard Code 3 Ò siren. The
standard siren must be used as your primary acoustical warning device.

WARNING!
!
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 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.
