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

SIRCTRL Input

- This input allows activation by an external source of either the Horn or other function.

Settable for +12 (default) or ground activation.

LITCTRL Input

- This input allows cycling by an external source through the lever switch positions. Settable for
