SA-400-17 Installation and Operating Instructions | Page 3 of 12 |
GENERAL DESCRIPTION
The SA-400 Siren Amplifier with Mechanical Tone is a premium unit designed for single or dual 100W speaker use. 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 rocker switch con- trols 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, per- forming the same function as the Siren push-button. An internal 8-position DIP switch allows selection of various options. 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 maxi- mum service life over a wide temperature range.
