CONGRATULATIONS on your purchase of a state-of-the-art vehicle security sys-  
tem. This system has been designed to provide years of trouble-free opera-  
tion. Due to the complexity of this system, it must be installed by an autho-  
rized dealer only. Installation of this product by any other person other than an  
authorized dealer voids the warranty. All dealers are provided with a preprint-  
ed dealer certificate to verify that they are authorized.  
THE SYSTEM REQUIRES NO SPECIFIC MAINTENANCE. Your remote control is powered  
by a miniature 12V battery, type GP23A, that will last about a year under nor-  
mal use. When the battery weakens, operating range will be reduced and the  
LED on the remote will light dim.  
YOUR WARRANTY card must be returned and the bar code serial number must  
not be removed. If the warranty card is not returned you don’t have a warran-  
ty. It is also necessary to keep your proof of purchase which reflects that the  
product was installed by an authorized dealer. Make sure you receive the  
warranty card from your dealer.  
THIS OWNERS GUIDE should help you to get the most out of your system. Please  
take the time to read it thoroughly, prior to using the system.  
NOTE: This product is designed for fuel injected, automatic transmission vehicles only. Use of this  
product in a standard transmission vehicle is dangerous and contrary the product's intended use.  
IMPORTANT! Most GM trucks and sport utility vehicles do not have an electric neutral safety  
switch. They use a mechanical switch that cannot prevent a remote start system from energizing  
the starter. When remote starting such a vehicle never leave the keys in the ignition or leave  
the vehicle parked in gear. Always put the vehicle in park before operating this remote start sys-  
tem. Activating this system while the shift lever is in a drive gear will cause the vehicle to lurch  
forward and may cause damage to persons or property as a result.

Using Your System  
Arming  
You can turn on, or arm, the system by pressing Button I of your transmitter  
for one second. When the system arms, you will hear a short siren sound, or  
chirp, and see the parking lights flash once. If the vehicle’s power door locks  
are controlled by the system, the doors will lock.  
While the system is armed, the Status LED will flash about twice a second,  
showing that the system is actively protecting your vehicle.  
If you hear a second chirp after arming and see the Status LED flash in  
groups, see Diagnostics section. This extra chirp is called Bypass Notification.  
The system can be programmed to arm itself automatically (called passive  
arming). If the system is programmed for passive arming, it will automatically  
arm 30 seconds after the ignition is turned off and the system "sees" you  
leave the vehicle by opening and closing a door. Whenever the system is in  
its 30-second passive arming countdown, the Status LED will flash twice as  
fast as it does when the system is armed.  
NOTE: If any protected entry point (such as a door or a switch-protected trunk or hood) is open,  
the system will not passively arm (unless forced passive arming is programmed on. See  
Programming Options section). Additionally, each time a sensor is triggered during the arming  
countdown, the 30-second countdown starts over.  
When armed, your vehicle is protected in the following ways:  
®
Light impacts will trigger the Warn Away signal. When triggered, the siren  
will chirp and the parking lights will flash for a few seconds.  
Heavy impacts will trigger the system. The trigger sequence is 30 sec-  
onds of constant siren and flashing parking lights.  
If a door is opened, the system will immediately start chirping the siren and  
flashing the parking lights. Three seconds later, the siren output changes  
to a continuous blast.This progressive response gives you time to disarm  
the system with your transmitter if you inadvertently open the door while  
the system is armed, while still providing instant response (even if the door  
is immediately closed).  
Turning on the ignition key will trip the same progressive response as  
opening a door.  
The optional starter kill prevents the vehicle’s starter from cranking.

Arming While Driving  
1
Your system can be armed while driving the vehicle! Simply  
press Button I on your transmitter while the vehicle is running.  
The system will chirp once and then once more to indicate  
that the ignition is on.The system will not respond to any input  
except the door triggers and the starter kill relay (if installed) will not be acti-  
vated. Once you have reached your destination, the system must be disarmed  
by pressing Button I on the transmitter once more. The siren will chirp twice  
and the LED will stop flashing. If you do not disarm the system, it will trigger  
when the any door is opened to exit the vehicle.  
Disarming  
1
To turn off, or disarm the system, press Button I again. You will  
hear two chirps, and the parking lights will flash twice. If power  
locks are controlled by he system, the doors will unlock. If the  
siren chirps either four or five times when disarming, see Diag-  
nostics section. This is called Tamper Alert.  
High Security Disarm  
1
Your system includes a High Security Disarm feature. During  
the trigger sequence, using the transmitter to disarm the sys-  
tem will only stop the trigger sequence (the siren will stop and  
the parking lights will stop flashing). However, the system will remain armed  
and the doors will stay locked. This is extremely useful if you must stop the  
system from sounding, but are unable to check the vehicle visually. The trig-  
ger will stop, but the vehicle will remain protected.  
To disarm with the transmitter during a trigger, press Button I on your trans-  
mitter. The siren will stop sounding. Next press Button I once more and the  
system will chirp four or five times (reporting the trigger) and disarm.  
Disarming Without a Transmitter  
This feature allows you to disarm the system without the transmitter should it  
be lost, damaged or disabled. In order to disarm without a transmitter, you  
must have the vehicle's ignition key and know where the valet button is. Be  
sure to check with the installer for the location of the Valet button.

Turn on the ignition. Push the Valet switch within 15  
seconds. The system should now disarm. If it does  
not, you may have waited too long, so turn the igni-  
tion off and on and try again.  
TM  
Silent Mode  
To temporarily turn off the arm or disarm chirps, use Silent ModeTM. Simply  
press Button II briefly before arming or disarming, and the confirmation  
chirp(s) will be eliminated for that one operation only. If you want the arm/dis-  
arm chirps turned off permanently, your dealer can do this for you.  
®
NOTE: The Warn Away response to lighter impacts is bypassed if the system is armed using Silent  
Mode™. This ensures that no chirps will be emitted by the siren in an area you want chirp free.  
®
The system is still fully able to trigger. Only the Warn Away response is defeated.  
Panic Mode  
If you are threatened in or near your vehicle, you can attract  
attention by triggering the system with your transmitter! Just  
press Button I for 1.5 seconds, and you will enter Panic Mode.  
The siren will sound and the parking lights will flash for 30 sec-  
onds. To stop Panic Mode at any time, press Button I on the  
transmitter again.  
2
Valet® Mode  
1
You can prevent your system from automatically arming and  
triggering by using Valet® Mode. This is very useful when  
washing the vehicle or having it serviced. In Valet® Mode, the  
system will not arm, even with the transmitter, but all conve-  
nience functions (door locks, trunk release, etc.) will work nor-  
mally.

®
To enter or exit Valet Mode with the Valet switch:  
Turn ignition to "run" position, then turn to "off" posi-  
®
tion. Press and release the Valet switch within 10  
seconds. The Status LED will light steady if you have  
®
entered Valet Mode, and it will go out if you exited  
®
Valet Mode.  
®
Using Remote Valet as you enter or exit the vehicle:  
Open any door. Press Button I (or the arm/disarm Button) Press button II (or  
the channel 2 button). Press Button I again. The Status LED will light steady  
®
®
if you have entered Valet Mode, and it will go out if you exited Valet Mode.  
Remote Starting the Vehicle  
Pressing Buttons I and II at the same time  
1
2
will begin the remote start sequence. The  
parking lights will flash to confirm that the  
motor is going to start. It is important to  
release the transmitter buttons as soon as  
the parking lights flash. If the buttons are pressed longer than  
two seconds, the system will stop the remote start sequence. About three  
seconds after the parking lights flash, the system will engage the starter until  
the vehicle is successfully running. If the motor is not running after six sec-  
onds, the system will stop cranking the starter. After three seconds, the sys-  
tem will try to start the motor again. If your motor is not running after three  
attempts, the system will stop the remote start sequence. It is not necessary  
to disarm your system before remote starting the vehicle. The shock sensor  
will be bypassed whenever the system is running the motor.  
IMPORTANT! It is unsafe to run a vehicle’s motor in a garage or other closed off area. Breathing  
the exhaust from the vehicle is hazardous to your health. Never activate the remote start system  
in an enclosed space.

Once the system has successfully started the motor, it will turn the climate  
controls on. If cooling or heating of the vehicle is desired, you must preset the  
controls to the desired temperature and turn the blower motor on. The motor  
will run for the selected time and the parking lights will flash or come on solid  
while the motor is running. (See programming Options page 13)  
Shutting Down the Remote Start System  
Pressing Buttons I and II again, during remote start operation, will shut down  
the remote start system and the motor will turn off. You can also shut down  
the remote start system by pressing on the brake pedal. You may want to  
enter the vehicle and drive it without shutting off the motor. To drive the vehi-  
cle without shutting down the motor:  
1
1. Disarm the system (if armed) by pressing Button I on the  
transmitter.  
2. Enter the vehicle and turn the ignition to the run position.  
3. Step on the brake pedal.  
The remote start system will be shut down when you step on the brake.  
However the motor will continue to run since the ignition has been turned on.  
You may now operate the vehicle as usual.

for the programmed time, every three hours for a total of six operations.  
To enter timer mode:  
1. Start the vehicle with the key.  
2. Press and HOLD Buttons 1 & 2 on the transmitter  
(or press and HOLD optional momentary switch.)  
3. Turn ignition OFF. (The vehicle will stop running.)  
1

4. Release transmitter (or push-button.)  
5. Engine will restart to confirm system is in timer mode.  
You may shut the vehicle down by pressing on the brake pedal or let it run for  
its programmed time. In either case, the engine will restart every three hours  
for six operations.  
To exit timer mode: Turn on the ignition with the key when the vehicle is not  
running.  
NOTE: If the system receives a shutdown input while operating in the timer mode, the engine will  
stop and restart in 3 hours!

Remote Start Take Over  
A vehicle equipped with this system can remain running after the key is  
removed. This feature is useful for those times when you will be out of the  
vehicle for short periods of time and would like to leave the motor running and  
the climate controls on. Before turning off the engine:  
1. Press Buttons 1 & 2 on the transmitter and release  
(or press and release the optional momentary switch.)  
1
2
2. Turn the ignition key OFF - engine will stay running.  
3. The engine will run until the programmed time elapses or  
shut down input is received.  
NOTE: While the brake pedal is being pressed, this feature will not work  
TM  
Nuisance Prevention Circuitry  
Your system has DEI's Nuisance Prevention Circuitry (NPC ). It prevents  
annoying repetitive trigger sequences due to faulty door pin switches or envi-  
ronmental conditions such as thunder, jackhammers, airport noise, etc.  
Here's how it works:  
Let's say the alarm triggers three times. Each time, the same sensor or switch  
is triggering the alarm.The three triggers are within 60 minutes of each other.  
NPC will interpret this pattern of triggers as false alarms. After the third trig-  
ger, NPC ignores, or bypasses, that sensor or switch (along with any other  
sensors or switches sharing the same zone).  
If the bypassed sensor tries to trigger the system while it is being bypassed,  
the 60-minute bypass period will start over. This ensures that a sensor that  
continuously triggers will remain bypassed.  
Doors are covered by NPC differently: If the alarm is triggered by an open  
door for three full cycles (one and one half minutes), the doors will be by-  
passed until the trigger ceases.  
NOTE: Arming and disarming the system does not reset this function! The only ways to reset a  
bypassed zone are for it to not trigger for 60 minutes, or to turn on the ignition. If testing your  
system, it is important to remember that the NPC programming can cause zones to be bypassed  
and seem to stop working. If five chirps are heard when disarming, NPC has been engaged. If  
you wish to clear the NPC memory, turn the ignition on.

Safety Features  
This system has several important safety features to ensure proper operation  
of the motor and prevent accidental damage to the engine or its components.  
Over and Under Rev Protection  
The system monitors the engine speed and will shut the engine off if the  
RPMs rise above or fall below programmed levels. This prevents damage to  
the motor due to fuel delivery system failures or other problems which may  
cause the engine to race.  
NOTE: The system uses a wire connected to the vehicle to sense engine speed. This wire must be  
connected for over and under rev protection to work.  
Shut Down Inputs  
The system uses several inputs to shut down the remote start operation of the  
motor or prevent it if they are active. The two most important are hood and  
brake inputs. The hood input will prevent the motor from starting as well as  
shut it down any time the hood is opened. The brake pedal will shut down the  
motor at any time during remote start operation, as well as preventing the  
remote from activating while it is being pressed.  
Starter Anti-Grind Circuitry  
Whenever the vehicle is remote started, advanced anti-grind circuitry within  
the unit will prevent the starter from being engaged, even if the key is turned  
to the start position. This prevents accidental damage to the starter motor  
should the key be turned to the start position during remote start operation.  
NOTE: Anti-grind circuitry only works when the remote start system is operating the motor and the  
Failsafe® starter kill relay is installed.

Diagnostics  
The microprocessor at the heart of your system is constantly monitoring all of  
the switches and sensors connected to it. It detects any faulty switches and  
sensors and prevents them from disabling the entire system. The micro-  
processor will also record and report any triggers that occurred during your  
absence.  
Arming Diagnostics  
If the system is armed with an input active (door open, sensor triggering, etc.)  
the unit will chirp once when arming and then one more time a few seconds  
later. This is called Bypass Notification.  
NOTE: Bypass notification will not occur when using Silent Mode or if chirps have been pro-  
grammed OFF.  
The system will ignore the input that was active when it was armed until it  
goes away. Three seconds later it will monitor that input normally. For exam-  
ple, if your car has interior light exit delay, and you arm the system before the  
interior light goes out, you may get Bypass Notification. Three seconds after  
the light goes out, however, the doors are monitored normally.  
Disarming Diagnostics  
Extra disarm chirps are the Tamper Alert. If four chirps are heard when dis-  
arming, the system was triggered in your absence. If five chirps are heard, a  
zone was triggered so many times that Nuisance Prevention Circuitry has  
bypassed that zone. In either case, the Status LED will indicate which zone  
was involved (see Table of Zones section).The system will retain this informa-  
tion in its memory, and chirp four or five times each time it is disarmed, until  
the next time the ignition key is turned on.

Code HoppingEXPLAINED  
The receiver and transmitters each use a mathematical formula called an  
algorithm to change their code each time the transmitter is used.This technol-  
ogy has been developed to increase the security of the unit. The control unit  
knows what the next codes should be. This helps to keep the transmitter “in  
synch” with the control unit even if you use the remote control out of range of  
the vehicle. However, if the transmitter has been pressed many times out of  
range of the vehicle, or the battery has been removed, it may get out of synch  
with the control unit and fail to operate the system. To re-synch the remote  
control simply press the arm/disarm button of the remote control several times  
within range of the vehicle. The alarm will automatically re-synch and respond  
to the transmitters normally.

High Frequency  
Your system transmits and receives at 434 MHz. This provides a cleaner  
spectrum with less interference and a more stable signal. Enjoy a phenome-  
nal increase in range - even in areas with high radio interference.  
Programming Options  
Programming options control what your system does during normal opera-  
tion, and require little or no additional parts. However, some may require addi-  
tional installation labor.  
The following is a list of the programmable options, with the factory settings  
in Bold.  
Active arming (only with the transmitter) or passive arming (automatic  
arming 30 seconds after the last door has been closed).  
Arming/disarming siren chirps on or off.  
Passive door locking (with passive arming) or active door locking (only  
when arming with the transmitter) . This feature only works if passive arm-  
ing has been selected for step one.  
The ignition-controlled door locking feature on or off. With this feature on,  
the doors will lock 3 seconds after the key is turned on, and unlock when  
the key is turned off.  
Note: If the door is open when the ignition is turned on, the doors will not lock.  
Panic mode enabled/disabled with the ignition on. (Some states have laws  
against siren capability in a moving vehicle).  
Automatic Engine Disable (AED) on or off. The purpose of the feature is to  
protect the vehicle from being stolen at all times, regardless of whether or  
not the alarm is armed. If AED is programmed on, the starter of the vehi-  
cle will be disabled 30 seconds after the ignition is turned off. Once the key  
is turned off, the LED will flash slowly (one-half its normal armed rate) to  
indicate the AED arming cycle. Thirty seconds later, the starter of the vehi-  
cle will be disabled. To start the car, it will be necessary to arm the car with  
the remote and then disarm it with the remote. It is also possible to disarm  
the AED feature by turning the ignition key to the “run” position and press-  
®
ing the valet button once. AED is also disabled when in Valet mode.  
NOTE: This feature will only function if the FailSafe starter kill relay has been installed.  
15

Forced passive arming on or off. If your system is programmed for passive  
arming and the forced passive arming feature has been programmed on,  
the system will passively arm after one hour, even if a protected entry has  
been left open. Forced passive arming ensures that the system will be  
armed if a door has accidentally been left ajar when leaving the vehicle.  
NOTE: When the system passively arms after one hour, the entry point that has been left open,  
and anything connected to the same zone, is bypassed and cannot trigger the system. However,  
the remaining inputs to the system are fully operational.  
TM  
TM  
Siren tones and chirp volume. The output of the Revenger Soft Chirp  
siren consists of six different tones in sequence. Any of these tones can be  
eliminated by your dealer, resulting in a unique, easily identifiable siren  
sound. The siren chirps can be either full volume or 6 decibels quieter  
than the full alarm blast.  
The engine can be programmed to run for 12 or 24 minutes. After the pro-  
grammed run time, the engine will shut down and will not restart, unless in  
timer mode.  
While the remote start system is running the engine, the parking lights of  
the vehicle can flash on and off or come on and light steady.

Glossary of Terms  
Control Unit The “brain” of your system. Usually hidden underneath the dash  
area of the vehicle. It houses the microprocessor which monitors your vehicle  
and controls all of the alarm's functions.  
®
FailSafe Starter Kill An automatic switch controlled by the security system  
which prevents the vehicle’s starter from cranking whenever the system is  
armed. The vehicle is never prevented from cranking when the system is dis-  
armed, in valet mode, or should the starter kill switch itself fail.Your system is  
ready for this feature, however installation of this feature may require addi-  
tional labor.  
Input A physical connection to the system. An input can be provided by a sen-  
sor, pinswitch or to existing systems in the vehicle, such as ignition or cour-  
tesy lights.  
LED Red light mounted somewhere in the vehicle. It is used to indicate the  
status of your system. It is also used to report triggers and faults in the sys-  
tem or sensors.  
®
Shock Sensor This system is packaged with a Stinger DoubleGuard shock  
sensor.This sensor is mounted in the vehicle and designed to pick up impacts  
to the vehicle or glass.  
Siren Noise generating device usually installed in the engine compartment of  
the vehicle. It is responsible for generating the “chirps” you hear, as well as  
the six tones you hear while the alarm is triggered.  
Transmitter Hand-held, remote control which operates the various functions  
of your system.  
Trigger or triggered sequence This is what happens when the alarm “goes  
off” or “trips. The triggered sequence of your system consists of 30 seconds  
of siren sounding and parking light flashing.  
®
Valet Switch A small push button switch mounted somewhere inside the  
vehicle. It is used to override the alarm when a transmitter is lost or damaged,  
®
or to put it into Valet mode.  
®
Warn Away response Lighter impacts to the vehicle will generate the Warn  
®
Away response. It consists of several seconds of siren chirps and parking  
light flashes.  
Zone A zone is a separate input that the alarm can recognize as unique. Each  
input to the system is connected to a particular zone. Often two or more inputs  
may share the same zone.

Security and Convenience Expansions  
Listed below are some of the many expansion options available. Please con-  
sult your dealer for a complete explanation of all the options available to you.  
Field Disturbance Sensor An invisible dome of coverage is established by  
the 508T “radar” sensor. Your system can react to any intrusions into this  
field with the triggered sequence.  
Backup Battery The 520T keeps the system armed, triggers the alarm and  
keeps the starter kill active if main battery power is disconnected.  
Electronic Hood Lock Prevents the vehicle’s hood from being opened  
whenever the system is armed, keeping thieves away from the system’s  
siren, the battery connections, and other components under the hood.  
Audio Sensor Metal on glass, glass cracking, and breaking glass produce  
distinctive acoustic signatures.The 506T audio sensor uses a microphone  
to pick up sounds, then analyzes them with proprietary acoustic software  
to determine if the glass has been struck.  
Power Trunk Release The Button II output of the system can operate a fac-  
tory power release for the vehicle’s trunk or hatch. Although the on board  
relay can control most power trunk releases, in some cases an optional  
relay is required. If the factory release is not power-activated, the DEI's  
522T trunk release solenoid often can be added.  
Power Locks This system offers lock outputs that can control some manu-  
facturers' power door lock systems. For other systems, additional parts  
may be required.  
®
Valet Start System For the ultimate in convenience, the Valet start system  
can start your vehicle, monitor engine functions and activate your climate  
control system with a push of a button! Over-rev protection, open-hood  
lockout, brake pedal shutoff and automatic timer shutoff are included.  
(Only for automatic-transmission, fuel-injected gasoline vehicles)  
PowerWindow Control Automatic power window control is provided with the  
529T and 530T systems. These can operate power windows, and can roll  
them up automatically when the system is armed, down when you trans-  
mit Button II or III, or both up and down.The 530T also provides one-touch  
switch operation.
