GENERAL DESCRIPTION
The SA400 Siren Amplifier is a premium unit designed for single or dual 100W
speaker use from a 12 volt DC power source (negative 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 rocker switch controls power. A permanently
mounted noise canceling PA microphone with front panel volume control overrides all
modes except Radio. An internal control is used to adjust Radio volume. 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. An internal 5-position DIP switch
allows selection of various options: Two-Tone to replace Phaser, Phaser disable,
Horn disable, short Manual and Horn Ring Cycler (HRC), which allows cycling
through Wail, Yelp, Phaser and Standby by pressing the horn ring when the function
switch is in the Horn position. The front panel is backlighted with LED's for night visi-
bility. This durable unit utilizes short circuit, high voltage, and reverse polarity protec-
tion systems for maximum service life over a wide temperature range.
