GENERAL DESCRIPTION
The SC-409 Light Control/Siren is a premium unit designed for single or dual 100W speaker use.
The primary 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 input is 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 on the front panel while Radio volume control is on rear panel. The
front panel is backlit with LED's for night visibility. The siren circuits utilize short circuit, high voltage, and reverse polarity protection systems for maximum service life. Output indicator light on
face for siren output diagnostics.
The SC-409 also provides a 4-position lever switch with LED indicators for primary lighting system
control of up to 60 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 20 amps per switch. Each output 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 unintentially. A video camera trigger output is activated with the lever switch or
programmed auxiliary switches.

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 dam-
age 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 damage, injury or death.
Qualifications - The installer must have a firm knowledge of basic electricity, vehicle electrical
systems and emergency equipment.
Mounting - Mount the unit for easy access by the vehicle operator. DO NOT mount in air bag
deployment area. Assure clearances before drilling in vehicle.
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 connection 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 unit with attached microphone, mounting bracket, microphone bracket with screws, mounting bolts, connectors and these instructions. Contact supplier immediately if any components are
missing.
MOUNTING
The mounting bracket supplied can be installed above or below the unit. Choose a mounting
location convenient to the operator and away from any air bag deployment areas. Inspect behind
mounting area for clearance. Assure adequate ventilation to prevent overheating. Consider wire
routing and access to connections, as well as microphone bracket placement. Install mounting
bracket to vehicle using 1/4" hardware (not supplied).
If mounting in a rack or console, make sure that mounting bolts do not enter case more than 1/4".
OPTION SWITCHES
Various options may be selected by turning on
or off DIP switches internally mounted on the
printed circuit board inside the case.
Accessing Option Switches - Remove the
12-Pin plug to prevent shorting then remove
the case cover by removing two screws at the
bottom rear corners of the unit.
SWA-1 (CUT_P) Cutout Input Polarity - The
cutout input is normally activated by positive.
Turn switch off to activate with negative.
SWA-2 (AUX_P) Auxiliary Input Polarity - The auxiliary input is normally activated by positive.
Turn switch off to activate with negative.
SWA-3 (TO) Timed Override - While 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 selected (turn on switch) the unit automatically goes back to the previous tone after 10
seconds without having to press Manual push-button again. In summary, press Manual button
once to override tone, then unit automatically goes back to previous tone.
SWA-4 (SWP) Sweep/Intersection Function (SWP/INT) - While in Wail, Yelp, or Phaser mode,
momentarily activating the auxiliary input will change the unit into sweep and intersection function.
See OPERATION section for further details. Turn this switch on to enable this function.

ELECTRICAL CONNECTIONS
Electrical connections to the unit are made using terminal block plugs and screw terminals located
on the back. A label on the unit identifies each terminal function. You should install the plug on
the unit before wiring. If the unit needs service the plugs can be easily removed without unwiring.
The power supply for the amplifier (12-P plug) must be capable of delivering peak currents up to
50 amps for adequate short circuit protection and reliable operation. The preferred source is
directly at the vehicle battery. The amplifier is fused.
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.
Wire Size and Termination - The diagram shows the minimum wire size used for each connec-
tion, along with recommended lead color. If the wire is longer than 10 ft. use the next larger wire
size. Use only high quality crimp connectors for installation on the vehicle.
Unit Enable Input Connection - 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.
Permanent power connection is not recommended as this keeps unit on unattended and may
drain battery. The lever switch may also be setup like a power switch for the entire unit. See
Instant On under OPTION SWITCHES section.
Auxiliary Input Connection - The Auxiliary Input allows activation by an external source of either
the Horn or other function. See OPTION SWITCHES section for polarity selection.
NOTE: Permanent disconnection of the vehicle horn is NOT recommended.
Cutout Input Connection - The Cutout Input turns off any siren tone output when activated, and
remains off until a control is activated or changed. See OPTION SWITCHES section for polarity
selection.
Radio Input Connection - Connect to radio output terminals or its speaker. The Radio Volume
control is on the back side of the unit and is a one time setting depending on the radio connected.
Set the volume on the radio itself for normal sound level on its own speaker. Then with Rotary
switch at Radio and unit powered up, adjust the Radio Volume control for desired output level.
Video Trigger Output Connection - A video camera trigger output is activated with the lever
switch or programmed auxiliary switches. See LEVER AND AUXILIARY CONTROL SWITCH
PROGRAMMING section.
