Congratulations on your purchase of our First Defense®, the first
car alarm designed to protect both You and Your Car.
First Defense®Protects Your Car:
Built-in 8 stage ceramic crystal shock sensor allows the user to
adjust from feather light to rock hard sensitivity, using the remote
control.
If your car is lightly bumped, First Defense®sounds a 3-second
pulse to ward off potential thieves.
If someone hits the car or climbs through a broken window, the
full alarm is triggerd.
Starter Kill prevents your vehicle from being started when the
alarm is armed. Many insurance companies provide a discount
to insurers whose vehilce is equipped with an ignition or starter
kill. Check with your insurance company.
The current sensor activates the alarm immediately when a door,
trunk or hood is opened (if these openings trigger a light) while
First Defense is armed.
Choose your own unique piercing 108dB siren sound from 8
different possiblilities.
First Defense®Protects You:
Panic Alarm lets you activate the siren and flash your vehicle's
lights to call for help or scare off would-be attackers.
Remote Light Control lets you remotely turn on your vehicle's
lights to light your way for 30 seconds.
Car Locator lets you quickly locate your car in crowded malls,
stadiums or other large parking lots.
Anti-Carjacking sounds the alarm after you are a safe distance
away from the carjacker.
Instructions for
First Defense®Alarm

20630 / 20930 Page 5Page 4 20630 / 20930
Step 1 - Mounting the Alarm and
Connecting the Ground
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!
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.

1) Slip the connector over
the wire you want to
attach to.
2) Push the First Defense®
alarm's wire (un-
stripped) as far as it will
go into the open end of
the connector.
3) Use pliers to press the
metal blade into the
wires.
4) Close the plastic cover
over until it clicks.
How To Use The Scotch-Lock
Connector
The diagram below shows how to use the blue Scotch-Lock
wire connectors to tap into the desired wires. This example
is for the parking light connection.
We recommend that you connect the YELLOW wire to
the parking light wire that measures +12 volts when the
parking lights are on. This will give a visual indication
from both the front and the rear of the vehicle.
Step 2 - Red +12 Volt Wire
Step 4-Yellow Lights Wire
This wire can power up either the headlights or the parking lights of
your vehicle. You cannot connect both. Connect the Yellow wire to the
light wire that shows +12 volts whenever the lights are turned on. This
output is a +12 volt relay output. This output will flash the lights for
panic alarm & car finder features, plus let you turn on your lights to light
your way at night.
Connect the RED wire with its in-line fuse holder and 15 amp fuse to
the +12 volt ("+") side of the battery terminal, using our eyelet
connecter. To do so, simply unscrew the battery terminal connector
nut and then slip the eyelet over the bolt and retighten the nut.
This optional wire will shut off the current sensing feature of this
alarm. This needs to be done if the vehicle's fan motor stays on after
the engine has been shut off on a hot day. Addtionally, some newer
vehicles will have electronic modules that come on and off periodi-
cally after the engine has shut down. If the siren periodically acti-
vates for no explanation after your car was recently parked, then you
may need to connect this wire to shut off the current sense feature.
To disable the current sense feature, connect the Blue wire to a con-
stant +12 volt source. To enable ignition sense, see Step 5.

Step 3 - Blue Current Sense Disable
Wire
Step 5-Orange Ignition Sense Wire
This wire will is only needed if you have connected the Blue current
sense disable wire in Step 3. This wire will sense the ignition of the
vehilce being turned on and therefore sound the alarm should the
ignition be turned on while the alarm is armed. Connect this wire to
a wire that measures +12 volts whenever the ignition is turned on.

20630 / 20930 Page 9Page 8 20630 / 20930
Step 6 - Coaxial Antenna Wire
Route the black Antenna Wire to the front of the grille of the car. The
thick triangular section of the wire is the actual antenna and must be
exposed and not positioned behind metal. This will allow for maximum
transmitter range. Secure the antenna to the front grille of the vehicle
using 2 cable ties. The more exposed the antenna, the better the
range. No antenna cable should remain coiled up - this will greatly
decrease range.
Step 7 - Quick Operational Test
At this point your alarm should be working. Before going on, test it
by pressing the middle (red) button for 1 second to get the CarFinder®
feature. If this feature is working, your alarm should be totally
functional. If you get no response from this test, go on to step 8. If
the quick operational test works, go straight to step 9.
Step 8 - Teaching Transmitters/Sensors
Step 5 - Violet Starter Kill Wire
The VIOLET wire is a transistor ground output that is active whenever
the system has been armed by the transmitter. This output is used
to engage a starter kill relay (optional and not included with this alarm)
to prevent the vehicle from starting whenever the alarm system is
armed. Follow the wiring diagram and instructions below if desired:
Connect the VIOLET wire to pin # 86 of a standard "Bosch" style
SPDT (Single Pole Double Throw) 30 Amp relay. Connect pin # 85
to a wire that provides +12 volts whenever the ignition key is in the
"Run" position. You may find this wire either behind the key area or
under the hood at the ignition coil/module. Locate the vehicle's starter
wire coming off of the ignition key area or under the hood before it gets
to the starter solenoid. This will be a wire that provides +12 volts only
while the key is in the "Start" position. Cut this wire in half. Connect
one side of the cut starter wire to pin # 30 of the relay. Connect the
other side of the cut starter wire to pin # 87a (the middle pin) of the
relay. Tie up the relay and wrap any exposed wires with electrical tape
to protect them from moisture and the elements. Make sure that all
wires are out of the way of moving or hot parts.
First Defense®comes with the transmitter pre-coded to the receiver.
If your alarm does not respond to the transmitter or you are adding
the optional Wireless Alarm Sensor, then do the following:
1) Pull out the 15 amp fuse for a few seconds, then replace it. The
lights will flash 4 times and the siren will chirp once confirming the unit is
in code learning mode.
2) Within 5 seconds of the first step, press button #1 (green) on your
transmitter until the lights flash once (usually hold the button for about
5 seconds), signifying that it has learned the code. If you have
additional transmitters, teach the receiver these by pressing the
second transmitter's button #1 (green) within 5 seconds of the
receiver learning the first transmitter code. (If you are adding a
Wireless Sensor, separate the magnet from the switch until the
receiver chirps once indicating that it has learned the sensor's code.)
3) After programming the last transmitter/sensor, wait 5 seconds for
the 4 exit light flashes. Your alarm is now ready to use! Follow these
steps again to relearn new transmitters, if necessary, in the future.

20630 / 20930 Page 11Page 10 20630 / 20930
TO ENTER PROGRAMMING MODE:
1) Press button #1 for 10 seconds and then
let go of the button only after you have heard
the siren sound.
2) By pressing the GREEN button #1 in the
siren sound selection mode, you can scroll
through the various siren sounds until you find
one you like (you will hear 2 seconds of the
selected siren sound each time you scroll to a
sound).
3) When you have settled on a favorite sound,
simply press button #2 (RED) to exit
programming mode and save the last sound
played. If you don't press any buttons for 5
seconds, you will automatically exit the
programming mode. Press button 1 for a
10 seconds, to
enter programming
mode
You can program the shock sensitivity level of your First Defense®to
maximize sensitivity while reducing false alarms.
TO ENTER PROGRAMMING MODE:
1) Press button #3 for 10 seconds and then let go of the button only
after you have seen the confirmation light flashes or you will not enter
the programming mode! Once you have seen the confirmation light
flashes, you are ready to program your shock sensitivity.
Step 9 - Adjusting Shock Sensitivity
Press button 3 for a 10
seconds, to enter
programming mode
2) By pressing button #1(GREEN) button
again you can scroll through the different
levels of shock. There are 8 levels of shock
and 8 corresponding tones. The higher the
number of flashes, the more sensitive the
alarm is to shock. Remember, you are
simulating the shock which the car would
feel if someone were tampering with your
vehicle). Be very careful when using level
7 or 8 as these are the most sensitve levels
of shock protection and this may cause your
unit to false alarm due to loud noises or
minor vibrations produced by large trucks
passing by, heavy machinery or heavy rain
and thunder.
3) When you have settled on a proper sensitivity level, simply press
button #2 (RED) to exit programming mode and save this sensitivity
level. If you don't press any buttons for 5 seconds, you will
automatically exit the programming mode with the setting of the last
number of flashes.
Step 10 - Choosing A Siren Tone
You can personalize your alarm's sound by selecting one of eight
different siren sounds.

Now everything is complete and it is time to try out the system.
•Press button #3 (yellow) and the headlights should come
on. They will turn off in 30 seconds or you can turn them off
by pressing the YELLOW button again.
•Press button #2 (red) for 1-2 seconds to get the CarFinder®
feature. The siren will sound for 1-2 seconds and the lights
will flash.
•Press and hold button #2 (red) for 3 seconds to get the Panic
mode. The alarm will sound and the lights will flash for 30
seconds. You can turn off the alarm by pressing the RED
button again.
•Press button #1 (green) for 1 second. You will hear one chirp
signifying that the alarm is now armed. Open the car door
and the current draw caused by the interior dome light coming
on will set off the car alarm. Hold down button #1 (green) for
2 seconds to turn off the alarm. Push the left button again to
rearm the system. This time, hit the vehicle with your fist to
simulate a thief breaking into your car - and test out the shock
sensor mode. Again, turn off the alarm by pressing button #1
(GREEN) for 2 seconds.
•Please note that any radio frequency type product is subject
to many conditions including interference from other products.
"Line-of-sight" range should be up to 400 feet in front of the
vehicle, but will be less from different angles of the vehicle
and under other conditions (such as being inside a building
or other structure, or being in a high radio interference area).
•The shock sensor and warn away have a zone bypass. If the
shock is triggered 4 times within a 12 hour period, then the
shock sensor zone will be bypassed for 12 hours. (Note:
Wireless sensors do not have a zone bypass).
Step 11 - Trying Out the Alarm Step 12 - Using with a Wireless Sensor
First Defense®is capable of working with Wireless Alarm Sensor,
models 20615 or 20915 (not included). The Wireless Alarm Sensor
is a small device that will monitor a door like those on the back of
pickup trucks, truck caps, Tonneau covers or those on a tool box. It
allows the user to have multiple alarm trigger sources without the
extra expense and hassle of hardwiring them to the alarm module.
First Defense®will work with up to any combination of up to eight
handheld transmitters or sensors. So, for example if you have two
handheld transmitters that you are using with the alarm, then the
maximum number of sensors that can be added are six for a total of
eight. The unit is powered by an included lithium battery, which has a
lifespan of 1 - 3 years.
The sensor consists of three pieces. The larger piece is the actual
sensor and built-in transmitter that transmits its status to the alarm
module. It is hardwired to a smaller piece that is a magnetic reed
switch. The other smaller piece is a magnet. The two smaller pieces
must be mounted next to each other using the self adhesive strips
that come with the sensor or small screws. The hardwired piece
needs to be mounted on a stationary portion or door frame, right next
to the other smaller piece which needs to be mounted on the piece
that swings open (i.e. the door). When the two are next to each other
the magnet piece will hold the reed switch piece closed. When the
magnet moves away from the reed switch, then the reed switch will
send a signal to the transmitter through the wires contected to it and
the larger transmitter piece will transmit a signal to the alarm that will
cause it to trigger.
The alarm will respond to a wireless sensor in one of three different
ways depending on whether the alarm is armed or disarmed and
whether the Wireless Sensor battery is low or not:
Unit is unarmed and the Wireless Sensor is triggered, then the alarm
module will flash the lights one time.
Unit is unarmed and the Wireless Sensor is triggered and the battery

Nothing Happens At All: Be sure that the fuse is securely in the
Red wire coming from the siren body and that power is reaching the
unit (test by using a voltage tester on the Red wire to find +12 Volts).
Also, review transmitter learning. Refer to step 8.
The Fuse Blows Every Time: Disconnect the Yellow wire and try
again. If the fuse doesn't blow with the Yellow wire disconnected,
then the only problem is that you are not on the low beam wire coming
off the back of the head lamp. Refer to step 4.
If The Headlights Don't Work: Using a Voltmeter or test light, make
sure the Yellow wire is Scotch-Locked to the low-beam headlight
wire that is "hot" (+12 volts) when the low beams are on. Refer to
step 4.
