This wire will become grounded when alarm is armed. Current capacity of this wire is 200mA. This output
can control starter disable, when intrusion is detected and system is triggered. Vehicle is prevented from
any unauthorized starting.
a). Find wire from starter solenoid (usually located on starter) and going to ignition switch.
b). When found, connect one probe of voltmeter to ground and connect other end of probe to starter wire.
It should receive "12 volts" only when ignition key in "START" position.
c). After locating correct wire, cut it in half, try to start vehicle. Engine should not "crank over".
d). If extended wires are needed, they must be exactly the same gauge as cut wire. Connect cut wire from
key switch to RED wire (pin #30) of relay and connect starter wire to WHITE wire (pin #87a) of relay.
e). Connect ORANGE wire from control module to ORANGE wire (pin #86) of relay.

2. Within 10 seconds push and release the valet switch. Alarm will stop sounding and enter the disarm
mode. You can now start and operate the vehicle normally.
OVERRIDE THE ALARM WITH PASSWORD PIN CODE: (See Alarm Feature IV - 2Programming):
Unlike valet switch easily found, and defeated, this security system allows the consumer to program a
password pin code, offering a higher level of security.
1. Enter the vehicle and turn the ignition switch to the 'ON’ position. (Alarm will sound.)
2. Within 5 seconds, enter your chosen first 10ths digit by pressing and releasing the valet switch.
3. Within 15 seconds of the last entered 10ths digit, turn the Ignition switch “OFF” then “ON”.
4. Within 15 seconds, enter your chosen second 10ths digit by press and release the valet switch.
5. Turn the ignition switch “OFF” position.

Note 1: You must override the alarm within 60 seconds. If not, the system will automatically re-arm.
EXAMPLE: To override the system with the password code 83, you would;
1. Enter the vehicle and turn the ignition switch to 'ON’ position. Alarm will sound.
2. Within 5 seconds, press and release the valet switch 8 times
3. Within 15 seconds of the last entered 10ths digit, turn the Ignition Switch “Off” then “ON”.
4. Within 15 seconds, press and release the valet switch 3 times
5. Turn the Ignition Switch to “Off” position.
[4] Chirps form siren/horn, [3] flash from parking light and LED will go off indicating system was disarmed.
J. VALET MODE: (System in Disarm or Valet mode):
The valet switch allows you to temporarily bypass all alarm functions, eliminating the need to hand your
transmitter to parking attendants or garage mechanics. When the system is in valet mode, all alarm
functions are bypassed, however the remote panic feature and remote door locks will remain operational.
To use the valet mode, the system must first be disarmed either by using your remote transmitter, or by
operating the Manual override sequence.
Enter Valet Mode:
1. From the disarmed condition, turn the ignition to the “ON” position.

2. Push and hold the valet switch for 2 seconds until the LED turns on. The LED will remain on as long as
the system is in 'valet mode'. One parking light flash confirms entering of valet mode.
Exit Valet Mode:
1. Return to normal operation, turn ignition 'on'.
2. Push and hold valet switch for 2 seconds. LED will turn off indicating system has exited the valet mode.
Two parking light flashes confirm exiting of valet mode.
Remote Valet Mode:
1. Press and release button on transmitter 3 times within 3 seconds to enter or exit valet mode.
2. One parking light flash will confirm you have entered ‘valet mode’ and two parking light flashes will
confirm you exited ‘valet mode’.
K. TRIGGER THE SYSTEM:
When armed, your vehicle is protected as follows:
1. Light impacts will trigger the warn-away signal.
2. Heavy impacts / Doors open / Hood open / Trunk open / Turning on the ignition key will trigger the
programmed sequence.
The starter disable relay (if installed) prevents the vehicle’s starter from cranking. The siren, horn, parking
lights, and dome light will turn on to alert of an intrusion for 30 seconds. Then it will stop and automatic
reset and re-arm. If the one of sensors or detectors is still active, the alarm system will sound a maximum
of 6 times of 30 seconds cycles.
NOISE ABATEMENT CIRCUIT: Your system has “Noise Abatement Circuit”. It prevents annoying
repetitive trigger sequences due to faulty door pin switches or environmental condition such as thunder,
jackhammers, airport noise, etc.
Here is how “Noise Abatement Circuit” works: The alarm triggers five times. Each time the same sensor or
switch is triggering the alarm, the “Noise Abatement Circuit” will interpret this pattern of triggers or false
alarms. After the fifth trigger, “Noise Abatement Circuit” ignores, or by pass, that sensor or switch until the
other sensor or switch is trigger.
“Noise Abatement Circuit” covers doors, hood, and trunk differently: If the alarm is triggered by an open
door for six full cycles (three minutes), the doors will be bypassed until the trigger ceases.
L. DOME LIGHT CONVENIENCE DELAY & SUPERVISION:
The alarm has a unique feature that will turn on your vehicle dome light as following:
1. Upon disarming, the interior lights will remain on for 30 seconds.
2. If the vehicle is intruded, the interior light will flash for the same duration as the siren.
Note: Turning ON the ignition switch or arming the alarm will turn off the dome light.
M. IGNITION CONTROL POWER DOOR LOCKS: (See Feature “II – 3” Programming):
1. Turn the ignition switch on and close all the vehicle’s doors. After 3 seconds, the system will
automatically lock the central locking system.
2. Turn the ignition switch off. The system will automatically unlock the central locking system.
N. TRUNK RELEASE / CHANNEL 3 OUTPUT: (See Alarm Feature “III –3” Programming):
Press and hold button on transmitter for 2 seconds to control trunk release or other devices.
Channel 3 is user-programmable timer output. You may program the built-in timer to send a ground signal
for any time interval between 1 second and 2 minutes. For instance, this timer output may be used to turn
on the headlights, power windows, or sunroof.
Note: Factory default setting at 1-second pulse grounded for trunk release output.
O. CHANNEL 4 OUTPUT:
Press the transmitter and buttons at the same time to active Channel 4 function. The momentary
output sends a ground signal for as long as the two buttons are pressed together (Up to 8 seconds).
P. POWER ON MEMONRY:
This security system is equipped with circuitry that will allow the unit to remember its alarm state if the
power is lost and then reconnected.
Q. ALARM UPGRADE:
This unit is capable of being upgraded to an alarm system to detect if a thief is trying to open a door, the
hood, or the trunk and has an input for a shock sensor to detect impact to the vehicle by a thief. If you
