GENERAL DESCRIPTION
The SA-430 Remote Siren Amplifier with Mechanical Tone is a premium unit designed for single or dual 100W speaker use. 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 selector switch controls the primary operating modes of Radio, Standby, Mechanical, Wail, Yelp, and Phaser. Two-Tone may optionally replace Phaser. A Siren push- button switch is provided for Manual control of the output tone or Horn override, depending on the selector switch and option switch settings. 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 push-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, Manual Mechanical, Manual Wail, and Horn Ring Cycler 2 (HRC2), which allows cycling through Mechanical, Wail, Yelp, and Phaser by tapping the horn ring when the selector switch is in the Standby 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.
