COMPLETING THE INSTALLATION

You will notice (3) additional wires, which come directly out of the
rubber wire exit boot from the siren control module, and are not part of
the main harness. These wires are used to customize the installation,
and are required in some vehicles.
1. Thin BLACK Wire
This is the antenna wire for the receiver that is built into the siren control
module. Fully extend this wire, and route it as high in the engine
compartment as possible, for maximum transmitter range.
2. WHITE Loop Wire
This wire exits the rubber boot, and immediately loops back into the
rubber boot.
Three minutes after the alarm has been armed, the voltage sensing
circuitry becomes active. This voltage sensing monitors the voltage
level of the vehicle, and when it sees a change ( i.e. a door opens, and
the interior light turns on ), the alarm is triggered.
Many vehicles incorporate an electronic cooling fan, which will auto-
matically switch on after the vehicle has been turned off. If this fan
switches on shortly after the alarm has been armed, the system will not
trigger due to the three minute delay.
If your vehicle does not have an electronic cooling fan which turns on
after the vehicle has been turned off, you may elect to by pass the three
minute arming delay of the voltage sense circuit. The system can be
modified so that six seconds after arming, the voltage sensing circuitry
becomes active. The three minute time delay can be eliminated by
cutting the WHITE wire loop. After cutting the WHITE wire loop,
individually insulate both ends of the wire with electrical tape.
Do not cut this loop if your vehicle is equipped with an electronic cooling
fan, as you will experience false alarms.
3. GREEN Loop Wire
This wire exits the rubber boot, and immediately loops back into the
rubber boot.
Cutting this wire will eliminate the voltage sensing feature of the alarm.
When this wire is cut, opening the doors will not trigger the system.
This loop wire should be cut only if you want to protect the vehicle from
sudden impacts to the glass or body panels, but do not want the alarm
to trigger when a door has been opened.
ADJUSTING THE SENSITIVITY OF THE SHOCK SENSOR
The purpose of a shock detector is to "sense" strong impacts to the
vehicle's glass and body panels, but ignore light bumps to the vehicle.
This alarm is programmed to report these impacts in two ways.
A lighter impact will cause the alarm to sound a series of short "chirps",
warning anyone tampering with the vehicle to stop immediately.
A more forceful impact will cause the alarm to sound for it's full 60
second cycle, informing you that a serious violation attempt has
occurred.
IMPORTANT ! Setting the sensitivity of the shock sensor too high will
cause false alarms. A substantial amount of force is required to
actually break automotive glass, and the shock sensor should be set
accordingly.
Before proceeding with the adjustment, verify that all screws securing
the siren control module to the bracket, and securing the bracket to the
vehicle, are securely tightened.
To adjust the shock sensor;
A. Locate and remove the small rubber plug on the back of the siren
control module.
B. Gently turn the adjustment screw fully counter - clockwise, then
clockwise approximately 1/8 of a turn. Do not over turn this screw,
as maximum rotation is approximately 270°. You should stop
applying pressure as soon as you feel a slight amount of resistance.
C. Close the hood, arm the alarm ( " 1 CHIRP " ), and allow six seconds
for the shock sensor to stabilize.
D. Firmly strike the front bumper of the vehicle with the side of a closed
fist, considering the amount of force required to break a window.
CAUTION ! Never perform this test on the vehicle's glass, as you may
break a window.
E. If the alarm did not sound, or if only the warning chirps were
activated, then the sensitivity will need to be increased. Disarm the
alarm, and open the hood to gain access to the siren control module.
F. Gently turn the adjustment screw approximately 1/8 turn clockwise
( increasing sensitivity ), and repeat the test.
G. Repeat this procedure until a firm strike causes the alarm to trigger,
and a less forceful impact causes the alarm to sound the warning
chirps.
H. When the adjustment is set, replace the rubber plug on the back of
the siren module.

OPERATING THE SYSTEM

1. Arming the System
A. Exit the vehicle, and close and lock all doors.
B. Press and release the larger arming button on the keychain
transmitter. The system will respond with one single chirp.
C. The red dash mounted L.E.D. will begin to flash, and after approxi-
mately six seconds, the shock sensing feature of the system will be
activated. The voltage sensing circuit will begin its countdown, and
after approximately three minutes, opening a light activated door will
trigger the alarm.
IMPORTANT ! If the WHITE loop wire was cut during the installation
procedure, the voltage sensing feature of the alarm will become active
six seconds after arming the system ( see COMPLETING THE IN-
STALLATION, WHITE Loop Wire ). You will not need to wait the three
minutes before opening a door will cause the alarm to trigger.
2. Protection While the System is Armed
A. Opening a door ( or any light activated entry point ), will cause the
alarm to immediately sound for the complete 60 second alarm cycle.
B. While the system is armed, the red dash mounted L.E.D. will
constantly flash, discouraging any would be thieves.
C. Any light impact to the vehicle glass or body panels will cause the
system to immediately sound the warning chirps, discouraging any
further attempts to enter the vehicle.
D. Any forceful impact to the vehicle will cause the system to immedi-
ately trigger for the complete 60 second alarm cycle. At the end of
the cycle, the alarm will re - arm itself, and resume monitoring the
vehicle.
3. Disarming the System
A. When you return to the vehicle, press and release the larger arming
button on the keychain transmitter. The system will respond with two
chirps.
B. The red dash mounted L.E.D. will turn off, indicating that the system
is disarmed, and it is safe to enter the vehicle.
4. Disarming After an Intrusion
When disarming, if the system responds with four chirps, you are being
alerted that the alarm was triggered during your absence. Additionally,
the red dash mounted L.E.D. will blink 3 times .. pause .. blink 3 times
.. etc., to provide an added visual indication that the alarm had been
triggered.
