GENERAL DESCRIPTION
The SC-1012 Remote Control Siren Amplifier with Light Control is designed for single 100W
speaker use.
The primary operating modes are Mechanical, Wail, Yelp, and Standby selected by 3-position
rocker switches. Momentary Horn Override, Momentary Phaser Override or push-on/push-off
Phaser operation while in the Mechanical, Wail, and Yelp modes. Manual siren control of Mechanical, Wail, and Yelp. Lights are controlled with two rocker switches. The SC-1012 may be
controlled with supplied switch panel or user supplied switches.
A DIP switch provides options to change tones, disable tones, HRC2 operation, and auxiliary input
polarity. The units utilize short circuit, high voltage, and reverse polarity protection systems for
maximum service life.
Sound Hazard - Sound level from siren speaker (>120dBA @ 10 feet) may cause hearing damage.
Do not operate siren without adequate hearing protection for you and anyone in immediate vicinity.

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 damage, injury or death.
Qualifications - The installer must have a firm knowledge of basic electricity, vehicle electrical
systems and emergency equipment.
Remote Panel Location - Locate the hand control for easy access by the vehicle operator, typically underneath the vehicle dashboard in a location away from the driver’s or passenger’s legs.
DO NOT locate in air bag deployment area. Mounting hardware is not supplied.
Amplifier Mounting - Flanges are provided for mounting (hardware not supplied). 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.

SW-5 Horn Enable - Turn this switch OFF to disable Horn tone. Horn replaced with Yelp.
SW-4 and 5 Tone Disable - All siren tones may be disabled except Manual, Wail and Yelp by
turning OFF both switches. Mechanical will be replaced with Wail. Phaser and Horn will be replaced with Yelp.
SW-6 Short Manual - The Manual siren tone will normally fall and die out when released. Turn
this switch OFF to have Manual stop immediately.
SW-7 Not Used
SW-8 Mechanical Fall - Turn this switch OFF for a quicker mechanical tone fall time.
HORN RING CYCLER 2 (HRC2) - Turn OFF DIP SW-2 and SW-3 to enable this feature. Also
connect the auxiliary input to the horn ring or other switch. While the siren is in standby, tap the
horn ring to bring the unit out of standby into Mechanical tone. Repeatedly tapping the horn ring
will cycle through Mechanical, Wail, Yelp, and Phaser tones. Tapping the horn ring twice quickly
will stop the siren tones and return the unit to standby. Pressing and holding the horn ring will
produce Horn tone until released. Then the siren will return to its previous siren tone or standby.
ELECTRICAL CONNECTIONS
Electrical connections to the unit are made using terminal block plugs and screw terminals located
on the amplifier. Labels on the unit identify each terminal function. Install the plug on the unit
before wiring. If the unit needs service the plug can be easily removed without unwiring. The
power supply of the unit 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 connection, 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.

Auxiliary Input Connection (Optional) - A momentary input typically connected to the horn ring
of the vehicle or other switch. See OPERATION section for auxiliary input functions.
NOTE: Permanent disconnection of the vehicle horn is NOT recommended.
The auxiliary input may be activated with positive or negative voltage. See Auxiliary Polarity
under OPTION SWITCHES section for proper activation polarity. Input current is 1 to 20 mA.

SIREN CONTROLS
MAN - STBY - AUTO SELECTOR SWITCH
A 3-position rocker selector switch controls the primary operating mode
of the siren.
Manual - Provides manual control of Mechanical and Wail tone rise and
fall or momentary Yelp depending on the position of Mech - Wail - Yelp
switch.
Auto - Keeps siren tone running (automatic rise and fall). Tone depends
on the position of Mech - Wail - Yelp switch.
Standby - A silent mode that may be overridden anytime.

Mech - A simulated mechanical siren tone. Tone may be changed or disabled. See OPTION
SWITCHES section.
Wail - A slower changing tone used on highways.
Yelp - A rapidly changing tone used in congested areas.
PHASER SWITCH
A very rapid changing tone used at intersections and very highly congested areas.
With selector switch in Auto, this tone override is toggled on and off by repeatedly
pressing switch. With selector switch in Standby, this tone override is momentary as
long as the switch is pressed. May be optionally replaced with Two-Tone or disabled. Two-Tone is two alternating frequencies like a European HI-LO. See OPTION SWITCHES section.

AUXILIARY INPUT FUNCTIONS
The switch or horn ring attached is intended to be momentary.
When the selector switch is in Auto, activating auxiliary will produce the Horn tone.
With selector switch in Standby, activating auxiliary will normally produce Horn tone. Different
tones are available. See OPTION SWITCHES section.

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,
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 fuse will blow before the unit is damaged. Disconnect the SPKR leads and replace
the fuse. If the amplifier makes noise with Wail mode selected and Enable Input powered the
amplifier is OK. Check the speaker or leads for possible shorting.
