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.

Installation and Operating Instructions
SC-411RD-10
INSTALLATION
Proper installation of the unit is essential for years of safe, reliable operation. Please read all instruction before
installing the unit. Failure to follow these instructions can cause serious damage to the unit or vehicle and may
void warranties.
SAFETY PRECAUTIONS
For the safety of the installer, vehicle operator, passengers and the community please observe the following
safety precautions. Failure to follow all safety precautions and instructions may result in property dam-
age, injury or death.
Qualifications - The installer must have a firm knowledge of basic electricity, vehicle electrical systems and
emergency equipment.
Mounting - Mount the control head for easy access by the vehicle operator. DO NOT mount in air bag deploy-
ment area. Assure clearances before drilling in vehicle. Mount the amplifier in a protected area with at least 1”
clearance on all sides for heat dissipation.
Wiring - Use wiring capable of handling the current required. Make sure all connections are tight. Route wiring
to prevent wear, overheating and interference with air bag deployment. Install and check all wiring before con-
nection to vehicle battery.
Testing - Test all siren functions after installation to assure proper operation. Test vehicle operation to assure
no damage to vehicle.
Keep These Instructions - Keep these instructions in the vehicle or other safe place for future reference.
Advise the vehicle operator of the location.
UNPACKING
Inspect contents for shipping damage. If found alert carrier immediately. Contents should include control
head with attached microphone, amplifier, (2) mounting brackets with screws, microphone bracket with screws,
legend sheet, (3) connectors, 25ft CAT 5e interconnect cable and these instructions. Contact supplier immedi-
ately if any components are missing.
MOUNTING - Control Head
Choose a mounting location convenient to the operator and away from any air bag deployment areas. Inspect
behind mounting area for clearance. Consider wire routing and microphone bracket placement. Connect inter-
face cable prior to mounting.
The control head can be surface, flush or bracket mounted using the supplied brackets and hardware. If longer
fasteners are used assure that screws do not enter rear of unit more than 3/8".
MOUNTING - Amplifier
Choose a mounting location that will assure at least 1” clearance on all sides with adequate ventilation to pre-
vent overheating. Inspect behind mounting area for clearance. Consider wire routing and access to connec-
tions. Make all wiring connections prior to mounting.
ELECTRICAL CONNECTIONS - Amplifier
Electrical connections to the unit are made using removable terminal blocks and screw terminals. Labels on the
unit identifies each terminal function. A CAT-5e cable connects between the control head and the amplifier. If
the unit needs service the plugs can be easily removed without unwiring. Connect all wires prior to applying
power to the unit and prior to final mounting. Attach leads by stripping 3/8", inserting into plug and clamp by
tightening screw. Make sure the screw is tight and the wire can't be pulled out. Failure to adequately tighten
the screw can result in improper operation or burning the connector and wire.
POWER Input - This is like a power switch for the entire unit. Connect to a positive circuit controlled by the
vehicle ignition switch, usually a terminal at the vehicle fuse panel.
OPTIONAL CONNECTIONS - Amplifier

SIRCTRL Input (Optional) - During installation, the siren control input may be connected to the horn ring or
other switching device. Activation of this input will produce Horn tone or other functions depending on Rotary
Switch position as shown in the above table.
LITCTRL Input (Optional) - During installation, the light control input may be connected to a momentary switch.
Activation of this input will cycle through the lever switch positions, with the lever switch overriding if moved.
CUTOUT Input (Optional) - During Installation, the cutout input may be connected to the vehicle door switch or
other switching device. Activation of this input will turn off any siren tone and remains off when deactivated until
a siren control is changed.
Timed Override (Optional) - With Rotary Switch in Wail, Yelp, or Phaser mode, momentarily pressing the
Manual push-button will toggle between tones overriding the Wail, Yelp, or Phaser tone. With this option se-
lected the unit automatically goes back to the Wail, Yelp, or Phaser tone after 10 seconds.
Sweep/Intersection Function (Optional) - The Sweep function is an automatic sequence of Yelp, Phaser, and
Horn tones allowing hands free operation. The Intersection function is a more rapid automatic sequence of
Yelp, Phaser, and Horn tones allowing hands free operation through intersections.
With Rotary Switch in WAIL, YELP, or PHSR position, tap the horn ring to start Sweep function. Tap the horn
ring again to start Intersection function. Repeatedly tapping the horn ring will switch between Sweep and Inter-
section functions. Tapping the horn ring twice quickly will return to Wail, Yelp, or Phaser mode. Pressing and
holding the horn ring will produce Horn tone until released. Then the siren will return to the Sweep or Intersec-
tion sequence.
Second Speaker Output (Dual Tone) - This unit provides a second siren amplifier that will produce independ-
ent siren tones based on option settings. Radio Repeat and PA are reproduced through both amplifiers.

LIGHT SYSTEM CONTROLS
A 4-position lever switch provides control of primary lighting functions. It also provides automatic activation of
the siren. Six additional programmable pushbuttons provided for auxiliary lighting or other device control. Two
dedicated switches operate directional control lights (“Arrow Stick”), with flashing indicators on the control panel.
Lever Switch - The lever switch by default provides progressive (additive) control of lighting functions. The
third position also provides Automatic Siren. The installer can change to non-progressive operation.
Automatic Siren - Position 3 of the lever switch provides Automatic Siren control. If the siren controls are set
where there is no siren tone output, the Automatic Siren will override with Wail or other tone. The cutout input
will stop the siren tone. This feature may be disabled.
Auxiliary Control Switches - Six lighted pushbutton switches are provided for various other lighting functions
or device control. The switch lights Red when activated. The switches may also be programmed for different
functions, and these switches may be combined with each lever switch position to automatically turn on and off.
Arrow Stick Control Switches - Two dedicated switches are provided to control traffic director lights on the
vehicle. Press left or right buttons to set the direction. Turning on both will set the output to left, right and cen-
ter. Lights show the operation selected.
Switch Legends - Different legends may be selected to match the device controlled. A sheet of labels is sup-
plied.
OUT/DIM - The backlighting and indicator lights can be dimmed or turned off by repeatedly pressing the OUT/
DIM button. An optional connection to the vehicle dash lights may also control this level. This button will light
whenever a siren tone is produced.
Video Trigger Output - A video camera trigger output is activated with the lever switch in position 1, 2, or 3.
Programmed auxiliary control switches may also activate the output.
Alert - While the lever switch or auxiliary control switches are on, an alert beep is sounded every 15 seconds.
This can be optionally disable.
DIAGNOSTICS
The unit monitors all outputs for faults, which are usually traced to shorted circuits. The unit indicates these
faults by flashing one or more lights and beeping. The following table shows fault indications and likely causes.

SERVICE
This unit is designed to provide years of reliable service under even the worst conditions. Many times there
may appear to be a problem with the unit when the true problem is in the speaker(s), controlled devices, or
improper installation. The following chart shows typical symptoms and possible causes.
A blown siren fuse doesn't necessarily mean that the unit is bad. If a speaker or speaker lead is shorted the
internal fuse will blow before the unit is damaged. Disconnect the speaker leads and replace the fuse. If the
OUT/DIM light comes on with power on and Yelp selected it is OK. Check the speaker(s) or leads for possible
shorting.
