Step 1 - Mounting the Unit and

Connecting the Ground

Mount the Siren under the hood as near to the front of the vehicle as
possible. It must be securely screwed into the metal frame of the
vehicle to pick up the shock vibrations during an intrusion or forced
entry. Secure the bracket tightly with one of the two self-tapping
screws provided. Use the other screw to run through the eyelet of
the ground terminal for the BLACK wire and then secure the other
side of the bracket to the vehicle. This will allow you to ground the
unit where you are mounting it. ALWAYS MOUNT THE SIREN SO
THE WIRES ARE HANGING DOWNWARD FROM THE CASE - this
will prevent any water buildup in the siren case.

Be sure to keep the siren and wires away from any moving parts.
For best results, mount the siren in the best location that allows the
sounds to emanate from the siren with the least amount of
obstruction.

Tools Needed:

• Drill

• Pliers

• Phillips Head Screwdriver

• Small Adjustable (crescent) Wrench

Warning: When working around the car battery, never allow
any metal tools to short across the two battery terminals or
from +12 Volts to ground!
