Congratulations on the purchase of your Crime Guard 250i6 vehicle security
system.ItismostimportanttonotethattheCrimeGuard250i6hasauniqueand
flexibledesign,whichallowsthe system to be installedinseveral configurations,
or levels of sophistication, and thus affects the total operations. The exact op-
erations of your system reflect this, and therefore it is most important that this
operations guide be carefully read and referred to. Regardless of how config-
ured, you’ll find your system both easy to operate and reassuring in its effective
theft deterrence capabilities.
Some principle components to become familiar with:
The Transmitter: Regardlessofhowthesystemisconfigured,theremotetrans-
mitter is used to operate the system. Two transmitters can operate the system,
and two are supplied with the system already programmed to operate it.
Everytransmitterhasitsownunique,invisiblecode,andthuscannotbeduplicated.
The transmitter has four buttons: an “Arm” button, a “Disarm” button and button
3 which can be used, if desired, to arm and disarm your system silently, and to
bypass the built-in shock sensor. The “Arm” and “Disarm” buttons also operate
the Remote Panic feature. Button 3 is also used in transmitter and features’
programming operations. Button 4 Can be used with optional Rec-43 to operate
an auxillary channel.

Step 1: After ensuring the system’sBluewireisnon-grounded,removeandthen
restore power to the system. The siren will chirp once, and the parking
lights, if connected, will flash 6 times.
Step 2: Immediately upon the single siren chirp, press and release
Button 3 on the first transmitter. The system will respond with one chirp.
Step 3: Within 6 seconds, press and release Button 3 on the second
transmitter to be programmed. The response will be one, then another
chirp, which indicates both transmitters have been programmed, and
the system is exiting Transmitter Programming Mode.
Shouldonlyone transmitter be programmed, after6 seconds of no programming
activity the system will sound two chirps and automatically exit Transmitter Pro-
gramming Mode. Also, if only one transmitter is programmed, one preexisting
transmitter code will be retained. Should it be desired to purge the preexisting
code, simply program the single new transmitter twice into the system.

Step 5: If programming multiple features, once the first feature has been config-
ured and acknowledged by 1 or 2 chirps, select the next feature by re-
peating Step 3 and Step 4.
Step 6:Onceallofthe selected features have been programmedas desired, the
system may removed from Features Programming Mode by allowing it
time to out via 10 seconds of no programming activity, or by pressing
and holding the Transmitter Button3 for 4 seconds. Regardless of
method,thesystem’sexit from Features Programming Mode is indicated
by 3 long siren chirps.
How to Program Transmitters to the System
Whenever the 250i6 is powered up, it automatically enters a Transmitter Pro-
gramming Mode. If the hood detection circuit (this is a Blue wire) is connected,
this wire must be in a “non-grounded” state when the system is powered up in
order for it to enter Transmitter Programming Mode. Where this applicable, sim-
ply hold the hood detection switch down, or temporarily disconnect it. “Powering
up” the system will entail first removing, and then restoring power and ground to
the system’s control module and siren assembly. This is easily accomplished

UponArming: • The siren will chirp one time.
• If connected, the parking lights will flash once.
• The optional starter interrupt, if installed, will engage.
• If installed, the Status Indicator Light will begin to flash slowly.
• Another option is having the doors automatically lock when-
ever the system is armed. This requires connecting an opt-
ional interface (the Omega “DM-1”).

Step 1: The system must be connected to power and ground, and be disarmed.
Step 2: Press and hold either transmitter’s “Disarm” and button 3 together
for 4 seconds; the system will chirp 5 times confirming entry to Features
Programming Mode.
Step 3: Within 10 seconds of entering Features Programming Mode, press and
release the transmitter’s Button 3 the number same of times that
equals the number of the feature to be programmed. After a pause, the
system will repeat the feature number with a like number of siren chirps.
Step 4: After the system acknowledges the feature to be programmed, press
eitherthe “Arm” Button to turn the feature on (thesystem’sresponse will
be 1 chirp), or the “Disarm” Button to turn the feature off (the system’s
response will be 2 chirps).
How to Program Features
The 6 programmable features, described on the previous two pages, are very
easily programmed by the following procedure:

Once Armed, If the System is Activated:
Page 7
System Armed & Activated
Once the system is in an armed state it monitors all protected zones, and if an
intrusion attempt is detected it will activate, or “trigger”.
An activation consists of the following:
• The siren will start sounding.
• The exterior parking lights, if connected, will flash on and off repeatedly.
An activation has a 30 second duration (or, optionally 60 seconds) unless the
system is disarmed using the transmitter or the Valet/Override switch. If all
protected zones are secure at the end of the activation, the system will stop and
In addition to detecting impacts to the vehicle and detecting a current draw from
the battery (example- interior light illuminating from opened door), the 250i6 has
a detection circuit which may be used to protect the hood, trunk or doors. If this
circuit is in a violated state when arming the system, the confirmation will be
three chirps instead of one. The system will still arm, but it will bypass the open
zone until the zone is secured; once secured, this zone is protected.
mode, and chirps made during the programming of features or transmitters.
4. Parking Light Illumination Upon Disarming: (On / •Off)
- This feature configures the system, upon its disarming, to either flash the
parking lights 2 times, or to flash the parking lights twice and then turn them
onfor30seconds. Thisfeaturemakesitsafertoapproachthevehicle when
disarming it at night by illuminating the area around the vehicle.
5. System Activation Cycle Duration: (•30 / 60 Seconds)
- Thisfeatureconfigures the system’sactivationcycletobe either 30seconds
or 60 seconds in duration before it automatically resets itself.
6. Shock Sensor Prewarning On or Off: (•On / Off)
- This feature turns on or off the prewarning only part of the shock sensor
operation. If prewarning is turned off, the “hard impact” part of the shock
sensor is still fully operable.

Programmable Features
The Crime Guard 250i6 vehicle security system has 6 programmable features
which allow the system to be customized. The following pages provide a brief
explanationforeachfeature,andnotesitsfactorydefaultsetting. Followingthese
descriptions are instructions on how to program the features.
• = Default Factory Setting
1. Current Sensing: (•On / Off)
- This feature enables the armed system to be activated should the system
detect a voltage spike or current draw in the vehicle’s electrical system.
2. Current Sensing Activation Delay: (•3 Seconds / 3 Minutes)
- Allows the option of a longer delay before activation by current sensing can
occur. Thisisforuseinvehicleswithequipment,suchascoolingfans,which
stayson for a short period of time after the ignition has been turned off.
3. Confirmation Chirp: (•On / Off)

-The activated system will instantly disarm.
The Status Indicator Light
The Status Indicator Light visually shows the status of the system and also
provides a high level of visual deterrence. The Status Indicator Light can be
mounted in the holder with the Valet/Override Switch, or mounted in a location
where it can be easily seen by the driver, as well as from outside the vehicle.
Status Indicator Light Off = The system is disarmed and in standby mode.
Status Indicator Light Flashing Slow = The system is armed.
Status Indicator Light Flashing Fast = The system has been activated.
Status Indicator Light On Solid = The system is in the valet mode.

Override.
EMERGENCY OVERRIDE-
How to Disarm the Security System Without the Transmitter:
Emergency Override:
Step 1: Withthesysteminthearmedcondition,enterthevehicleviathedriver's
door (be aware that the alarm will likely activate when the door is opened).
Step 2: Using your key, turn the vehicle’s ignition to the "On" position.
IMPORTANT: in addition to the inclusion of the Valet/Override and Status
Indicator Light, the Crime Guard 250i6’s “ignition input” wire must also be
connected. If the Crime Guard 250i6 was not installed with the Valet/Override
Switch,ortheignitioninputbeingconnected,theonlywaytobypass,orturnoffthe
system is to locate and unplug the control module and siren assembly must be
unplugged from its wiring harness!

Remote Panic can be activated anytime, whether the vehicle’s ignition is turned
on or off, and has a 60 second duration (regardless of the 30 or 60 second acti-
vation setting) unless a transmitter is used to stop it.At the end of the 60 second
cycle,thesystemwill reset and be in either the armed state (if Remote Panic was
activated by the “Arm” button) or in the disarmed state (if Remote Panic was
activated by “Disarm”).
Page 11
To Deactivate Remote Panic: Press & Release either the “Arm”
Button OR the “Disarm” Button
Once Remote Panic has been activated, rather than wait for the system to stop
automatically at 60 seconds, the transmitter may be used to stop the Remote
Panic operation. Simply press and release the “Arm” or “Disarm” button. While
pressing either of these buttons will stop the Remote Panic operation, please
note that the system’s armed or disarmed status will depend upon which button
was used to activate the Remote Panic in the first place. For example, if the
“Arm”buttonwas pressed and held to activate Remote Panic, and if the“Disarm”
buttonwasusedtostopit,the system will revert to the armed statewhenRemote
Panic is stopped, because the “Arm” button was the one used to activate the
operation.
Valet Mode prevents the system from becoming armed. Valet Mode is designed

- The Status Indicator Light will turn on solid Red and the siren will chirp once to
confirm Valet Mode. Now the system cannot become armed.
To Exit Valet Mode:Simply Press & Release the
Valet Switch.
- The Status Indicator Light will turn off to confirm that the system has exited
ValetModeandreturnedto a “standby”mode. Normalarming operations may
be resumed.
The security system must be disarmed, and the vehicle's ignition may be "On" or
"Off" when entering or exiting Valet Mode. If the system is armed, or activated, if
the transmitter is lost or inoperable an Emergency Override must be performed!

TheCrimeGuard250i6vehiclesecuritysystemisequippedwithabuilt-in“shock”
sensor which detects impact to the vehicle. As vehicles differ structurally, and
mountinglocations of the system control module vary,this shock sensor is easily
adjustable. Theshocksensoradjustmentisfoundontherearofthecontrolmodule
and siren assembly, below a weatherproofing rubber cover plug. Turning the
adjustment clockwise increases sensitivity, and turning the adjustment counter
clockwise decreases the sensor’s sensitivity. If adjustments are made to the
sensor, the rubber plug must always be replaced.
Shock Sensor & Prewarning
Bypassing the Auxiliary Sensor: If desired, the system may be armed, but
without the auxiliary sensor being part of the system’s protection. Upon arming,
immediately after the single arming confirmation chirp, simply press and release
the Transmitter’s Small Button; the system will chirp the siren once again to
confirmthatthesensor is bypassed. When the sensorhasbeenbypassed,itwill
not activate the alarm, nor will it have the prewarning operation.

As noted in the “Introduction” section of this booklet, the Valet/Override Switch is
not essential, but its inclusion offers several convenience benefits. The Valet/
Override Switch can perform two distinct functions: accessing Valet Mode and
performing an Emergency Override of an armed and activated system. It is
important that you know the location of the Valet Switch; a Valet Switch and LED

Mounting the Control Unit and SirenAssembly: Find a location in the engine
compartment away from the extreme heat of the engine and manifolds. A suit-
able location will offer a firm mounting surface, will also allow sound dispersion
out of the engine compartment, and not be accessible to a thief.The control unit
andsirenassemblymustbepointeddownwardtoavoidmoisturecollectinginthe
unit and to enhance sound dispersal. The unit's wires should be securely con-
nected to the appropriate vehicle wires with the proper terminals, connectors, or
by soldering and tape or heat shrink tubing for insulation. Wires routed through
panels such as the firewall should always be protected by an existing or added
grommet.A vehicle security system is also more effective if its wiring is wrapped
or enclosed in a protective sleeve which matches that already found in the ve-
hicle protecting the factory wiring.

The 250i6 is a uniquely engineered design; it can be installed and have basic
operations with the connection of only two of it’s nine wires. The connection and
utilization of its remaining wires greatly adds to the operational sophistication of
this system, and it also features two independent parking light wires.
Ofthesystem’snine wires, the Red, Black,twoWhites,andYellowwires in most
cases can be connected within the engine compartment. The Blue wire, if it is
connected to a hoop pin switch only, will also remain within the engine compart-
ment. Ifitisto also be connected to a trunk pin switch, or possibly the dome light
circuit to protect the doors, will need to be routed into the vehicle interior through
the firewall. The Gray, Pink and Orange wires will need to be routed through the
firewall and into the vehicle interior. Installation Insert Page 11

in the engine compartment, the easiest way to locate the parking light wire is to
access a corner running light on the fender, or a front parking light in the front
bumper or fascia. The correct wire will typically show +12 Volts when the
headlight switch is in the "Parking Light" and "Head Light" positions. It is also a
goodideatoensurethatthe targetwireis“non-rheostated”,oractuallythedash
illumination circuit. While metering the wire, operate the dash light dimmer
control. The correct wire will show no change in voltage when the dimmer is
operated. DonotattempttoflashtheparkinglightsbyconnectingtheWhitewire

rarely found in the engine compartment, but testing the target wire anyway is
easy. Afewvehicleshave separate left andrightsideparkinglights. When left
& right parking lights are on separate circuits, simply connect one White wire to
eachparkinglightcircuit. The White wiresshouldbeconnectedto the vehicle’s
parking light circuit only- flashing the headlights is not recommended, as it is a
higher current draw, and halogen headlights are not designed to be rapidly
turned on and off.
Yellow Wire - (+12 Volts Ignition Input): Another wire which is not absolutely
necessary for basic system operation, the Yellow wire is an ignition "on" input to

IMPORTANT: When wiring more than one of the vehicle's circuits and/or addi-
tional circuits to this wire, diode-isolation is usually required to maintain each
circuit's proper operation (diodes are available at most electronics stores). An

White Wires - (+12 Volts Flashing Light Outputs): While not necessary for the
Crime Guard 250i6’s basic operation, these wires greatly enhance the system’s
operation, are usually very easy to connect. These are +12 Volts outputs for
exterior flashing light confirmation, and to attract attention to the vehicle if the
security system is activated. Although two White wires are supplied, in most
cases both of these wires are connected to a single wire in the vehicle. The
exceptionwillbecertainvehicles, primarily ofEuropeanmanufacture,whichhave
the left and right parking lights as separate circuits. In these cases, one White

these wires to the vehicle's parking light circuit. As the 250i6 is mounted
