INSTALLATION
Proper installation of the system is essential for years of safe, reliable operation. Please read all
instruction before installing the system components. Failure to follow these instructions can
cause serious damage to the components 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 horn system 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

MOUNTING
Amplifier
The amplifier is waterproof and may be located under hood in the engine compartment or other
areas. Allow clearance for wiring. Inspect behind mounting area for clearance. Use #8 screws
(supplied loose) for mounting.
Speaker
The speaker is weather resistant and is intended to be mounted on the outside of the vehicle or
under front hood. Mount the speaker facing forward and as far forward on the vehicle as possible
to minimize sound exposure to occupants. Choose a location that minimizes obstructions in front
of the speaker to maximize forward sound. Attach the speaker to a sturdy part of the vehicle to
prevent vibration and possible damage. Attach the speaker angled slightly toward the road so the
front openings will drain off any fluids. Cover openings of speaker while drilling any holes.
DO NOT get metal shavings inside the speaker.
Switch Panel
Mount the switch panel underneath the vehicle dash board using #8 screws (supplied loose).
Locate the panel away from the driver’s or passenger’s legs. Allow clearance for wiring. Inspect
behind mounting area for clearance. Make all electrical connections before final mounting.
ELECTRICAL CONNECTIONS
Amplifier
Electrical connections to the amplifier are made using butt splices (not supplied). The butt splices
need to be waterproof when unit is mounted under hood or other weather susceptible areas.
A
label on the amplifier identifies each lead function. An in-line fuse is provided on the amplifier.
The power supply for the amplifier must be capable of delivering peak currents up to 50 amps for
adequate short circuit protection and reliable operation. Most vehicle horn circuits with relays
provide adequate power on the vehicle horn side of the relay. However do not provide power to
both the vehicle horn and this amplifier from one horn relay circuit as this will exceed circuit rating.
NOTE: Permanent disconnection of the vehicle horn is NOT recommended.
Switch Panel
Electrical connections to the switch panel are made using 3/16” quick-connect terminals (supplied
loose).
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.

OPERATION
USING SWITCH PANEL
In an emergency situation, set the HORN SELECT switch to AIR and turn on the LITE switch in
one sweeping motion. When the horn ring on the vehicle is pressed the amplifier and speaker
produce a simulated air horn sound. A power indicator on the amplifier also lights up. The power
indicator is located on the same surface where wires emerge from amplifier.
When the emergency is over, turn off the LITE switch and set the HORN SELECT switch to VEH
in one sweeping motion. When the horn ring is pressed the regular vehicle horn will sound.
NOT USING SWITCH PANEL
As soon as power is applied, the amplifier and speaker produce a simulated air horn sound and
the power indicator lights up. The power indicator is located on the same surface where wires
emerge from amplifier.

SERVICE
The complete system consists of the amplifier, speaker, and switch panel components along with
the wiring and electrical connections. A blown fuse on the amplifier does not necessarily
mean the amplifier is bad. If the system stops functioning or exhibits problems, first check that
the wire and electrical connections to each component are OK then check the following.
On the switch panel, check for power into (center terminal) and out of the switch. On the HORN
SELECT switch, check for power while pressing the horn ring. If there is not power into the
switch, check wire for bad connections and check fuses or breakers in the circuit. If there is
power into but not out of the switch, the switch itself may be bad.
While activating the amplifier (with horn ring), look for the power indicator to light up. If it
lights up the amplifier is OK. If not, check the fuse on the amplifier. If the fuse is OK then check
the RED and BLK power input leads for good supply and ground connections. If power into the
amplifier is OK then the amplifier may be bad.
If the fuse on the amplifier is blown, disconnect the speaker leads at the amplifier and replace
the fuse. As before, activate the amplifier and look for the power indicator to light up. If the fuse
blows again then the amplifier may be bad.
If the power indicator on the amplifier lights up, disconnect the leads at the speaker and check
the speaker inputs with an ohm meter. If the reading is less than 1 ohm or reads as open circuit
then the speaker may be bad. If the ohm meter reading is OK then the wiring or connections
between the amplifier and speaker may be faulty.
The following chart shows typical symptoms and possible causes.
PROBLEMS
