GENERAL DESCRIPTION

The SC-407 Light Control/Siren is a premium unit designed for single or dual 100W speaker use and lighting control. The primary siren operating modes are Yelp, Wail, Standby and Radio. A Noise Canceling PA Override and push-button Horn Override are available in all modes except Radio. A push-button is provided for push-on/push-off Phaser operation in the Yelp and Wail modes, and Manual siren control in the Standby mode. The Phaser function can be optionally replaced by Two-Tone or disabled entirely with program jumpers. Another option allows cycling through Wail, Yelp, and Phaser by pressing the horn ring when the function switch is in the Standby position (Horn Ring Cycler 2). A latching siren cutout input is provided for connection to a door switch, etc. to disable the siren when exiting the vehicle. Radio and PA volume controls are provided on the front panel. The front panel is backlighted with LED's for night visibility. This compact unit utilizes short circuit, high voltage, and reverse polarity protection systems for maxi- mum service life.

The SC-407 provides a 4-position lever switch with LED indicators for primary lighting system control of up to 60 amps total, and four illuminating rocker switches provide additional lighting control with 20 amp per switch rating. The lever switch provides automatic Wail or Yelp siren activation in position 3 (can be disabled). The light controls are directly connected via heavy lead wires to assure high reliability.
