Installation Instructions
WARNING: Never install this product with the engine running
and be certain to keep the alarm's wires away from moving
parts.
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!
Step 1 - Mounting the Alarm and
Connecting the Ground
Mount the Siren under the hood as near to the front of the vehicle as
possible. The siren must be securely screwed into the metal frame
of the vehicle to pick up the shock vibrations during an intrusion or
forced entry. First, unscrew the mounting bracket from the siren.
Secure the bracket tightly to the frame of your vehicle with the two
self-tapping screws provided. Then secure the siren to the bracket.
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.
The BLACK ground wire must be connected to the negative (-)
terminal of the vehicle's battery or another suitable ground location
on the vehicle's chassis.
