GENERAL DESCRIPTION
The SC-411RD Remote Light Control/Siren is a premium unit designed for dual 100W speaker use. The pri-
mary operating modes are Radio, Cycler, Standby, Yelp, Wail, and Phaser. A Noise Canceling PA Override
and push-button Horn Override are available in all modes except Radio. A push-button is provided for toggling
between Wail, Yelp, and Phaser tones, and Manual siren control in silent modes. The Phaser tone can be
optionally replaced by Two-Tone or disabled entirely. Auxiliary inputs are provided for connection to horn ring
circuit or switch. A latching siren cutout input is provided for connection to a door switch, etc. to stop siren tones
when exiting the vehicle. PA volume control is on the front panel while Radio volume control is on the amplifier.
The front panel is backlit with LED's for night visibility, dimmable with a front panel switch and/or connection to
dash lights. The siren circuits utilize short circuit, high voltage, and reverse polarity protection for maximum
service life. An indicator light on face is provided for siren output diagnostics.
The SC-411RD also provides a 4-position lever switch with LED indicators for primary lighting system control of
up to 50 amps total and automatic siren tone in last position. Six programmable lighted push-button switches
with replaceable legends provide auxiliary lighting or other device control up to 10 amps per switch. Each out-
put is fused and monitored with visual and audible indicators for diagnostics. An alert periodically sounds (may
be disabled) when outputs are on to help prevent leaving lights on unintentionally. A video camera trigger output
is activated with the lever switch or programmed auxiliary switches. Two switches are dedicated to arrow stick
control (left, right, center) with function indication and specific control outputs.
All optional settings are programmed from the remote head face. These settings are synchronized between the
head and amplifier using our QuickClone™ duplication technology, a quick-copy feature for simple transfer of
option setting among multiple heads and amplifiers for efficient fleet installations.
