GENERAL DESCRIPTION
The SA-430 Siren Amplifier is a premium unit designed for single or dual 100W speaker use
from a 12 volt DC power source (negative ground). The control head is only 1 inch deep and
can be installed in minimum clearance areas. Connection between the control head and
amplifier is via a single lead wire with common ground.
A 6-position rotary switch controls the primary operating modes of Phaser, Yelp, Wail,
Manual, Horn and Radio. A Siren control button is provided for control of the output tone
when in the Manual mode, and control of Horn and Yelp Overrides, depending on the function
switch setting. An independent toggle switch controls power. A hole is provided in the
amplifier to adjust Radio volume.
Depending upon the version, the microphone may or may not be directly mounted to the
control head. Units with an “F” suffix have the microphone permanently mounted to the
faceplate. Units with an “FX” suffix are provided with an extension harness and connectors for
remote mounting of the microphone.
An auxiliary input is provided for connection to a positive or negative horn ring circuit or
switch, performing the same function as the Siren button. A latching siren cutout input is
provided for connection to a door switch, etc. to disable the siren when exiting the vehicle.
An 8-position DIP switch on the amplifier allows selection of various options: Two-Tone to
replace Phaser, Phaser disable, Horn disable and Horn Ring Cycler (HRC), which allows
cycling through Wail, Yelp, Phaser and Standby by tapping the horn ring when the function
switch is in the Horn position. The front panel is backlighted with LED's for night visibility.
This durable unit utilizes short circuit, high voltage, and reverse polarity protection systems for
maximum service life over a wide temperature range.
