TROUBLESHOOTING GUIDE
See page 19 for testing tips.
SITUATION
Poor transmitter range.
Transmitter LED doesnt flash when button pushed.
Transmitter not work when siren sounding.
Alarm not respond to pressing transmitter button.
Under passive arming (switch sensing), siren does
not chirp when the last door/hood/trunk is closed.
Under passive arming (current sensing), siren does not
chirp when the last door/hood/trunk is closed.
Not all doors trigger the alarm.
Too many false alarms.
When alarm triggered, pressing transmitter shuts
siren and lights OFF, but alarm stays armed.
More than one chirp when arming (active mode).
Siren does not chirp.
Siren chirps or LED flashes while driving.
Siren continually emits a strange quiet sound.
Cut main power wire (red wire), and alarm looses
power.
Testing of hardwired zone, on-board or auxiliary
sensor, or current sensor does not trigger alarm.
Engine does not start and LED is steady on after
car has sat for some time with alarm disarmed.
SOLUTION
Replace the battery.
Mount alarm brain in another location.
Fold or roll up (do not cut) alarm brain antenna.
Make sure battery contact with clip is tight and clean.
Replace the battery.
Replace the transmitter.
Increase the distance between siren and alarm brain, and
make sure the two are not grounded together.
Re-code the transmitter.
Check blue or blue/white wire (depending on which switch) at
brain with VOM. If ground when door or hood or trunk
open, and not when closed, then problem with wire harness or
brain. Otherwise, check switch, wire, or connection.
Remind your customer about the feature, or program it off.
Connect trigger wire to under-dash courtesy lights, or
connect individual pin switches to each door.
Reduce shock/glass-break sensor sensitivity, and double-
check all door and hood/trunk pin switches.
This is a feature of the alarm, and not a problem.
Check all openings to see which is not closed properly.
Reprogram to restore chirp.
Check the connection.
Check the alarm brain ground for good contact, and make
sure it is not grounded together with siren.
Connect these two wires to separate sources of +12VDC.
(Feature not available for (-) parking light systems).
Wait 4 sec. (hardwired triggers) or 10 sec. (current sense)
after arming before testing.
Remind your customer how Automatic Starter Disable
works, or program it off.
POSSIBLE PROBLEM
1. Low or dead transmitter battery.
2. Metal of car body reflecting RF waves.
3. RF interference.
1. Loose battery connection.
2. Low or dead transmitter battery.
3. Defective transmitter.
Alarm brain too close to siren.
Transmitter not matched to alarm.
Door/hood/trunk pin switch not connected, or
broken, or its height is not adjusted properly.
Not a problem With current sensing, alarm can
only detect open doors, not closed doors.
Door switches are isolated by diodes.
Shock or glass-break sensor, or door pin
switches, or current sensing.
Patented Stay-Safe Disarm.
Alarm detects open circuit, does zone bypass.
Set for chirp delete.
Yellow wire of 10-pin connector loose.
Poor alarm brain ground.
Fused orange wire and fused red wire
connected to the same source.
Tried to test the triggers too soon after the
alarm was armed.
Automatic Starter Disable is engaged.

A. Testing RF reception and range — To test if
the alarm brain is receiving signals from the
RF transmitter, and to test range, watch the
alarm status LED. The LED should turn on
steady as long as any button on the RF
transmitter is being pressed. If the LED does
not turn on, this means the alarm brain is
not receiving the transmitter signal.
B. Testing wire connections — Often, when
trying to trace a problem between a
trigger input, wiring, and the alarm brain,
one place to test is at the alarm brain
itself. Set the VOM for (+) or (-),
depending on the trigger, then probe the
appropriate wire near the alarm brain
while testing the trigger. For instance, to
determine why a (-) door trigger is not
TIPS FOR TESTING THE ALARM
working, probe and test the BLUE WIRE of
the 6-pin connector near that connector. If
the BLUE wire shows (-) when the door is
opened, then the problem may be caused
by the user not arming the alarm correctly,
or the alarm brain may be defective. But if
the BLUE wire does not show (-) when the
door is opened, the problem may be a
loose or defective pin switch or wire
connection.
C. Sensor delay times — The various sensors
have a short 4-second delay from the time
the alarm is armed until the sensor can be
triggered. Therefore, after arming the
alarm, wait until after the delay period
before testing the sensor to be sure that
sensor is operating properly.
Page 2 Page 19
The alarm can learn a max. of 4 remotes. RF
Code Wash™ deletes all previous remotes
when any new remote is learned. This prevents
unauthorized use of lost or stolen transmitters,
and alerts the user if someone has secretly
code learned a new transmitter. However, it
also means that, when code learning is being
done, ALL THE USER'S TRANSMITTERS MUST
BE CODE LEARNED AT THE SAME TIME.
A. Procedure:
(1) Disarm the alarm.
(2) Open a car door.
(3) Turn the ignition switch on and then off
three times.
(4) Press the VELT button three times
within 15 seconds of turning the
ignition off the third time. The siren
chirps once.
(4) Within 15 seconds, push button #1 of
the first transmitter to be learned. At this
time, all previous codes are deleted,
and the alarm learns this transmitter's
code. 1 chirp confirms code learned.
(If no button is pressed within this 15-
second period, code learning is exited,
and old codes are retained.)
(5) Within 15 seconds, push button #1 of
the second transmitter to be learned (if
applicable). 1 chirp confirms learned.
(6) Repeat step (5) until all transmitters are
learned. The siren chirps once for
each transmitter when its code is
successfully learned.
B. Exit the code learning procedure — The
alarm chirps the siren two times, exits the
code learning mode, and is disarmed after
learning the fourth transmitter's code, or if
you turn the ignition switch on, or if you do
nothing for 15 seconds.
C. Enforcer 300C vs. Enforcer 300L — The
Enforcer 300C uses SECO-LARM's
CODEBUMP™ code-hopping system. All
transmitters come coded by the factory,
and cannot be recoded by the installer or
user. The Enforcer 300L uses fixed-code
transmitters.

GENERAL CONSIDERATIONS
IMPORTANT: THIS ALARM IS INTENDED FOR
INSTALLATION BY QUALIFIED PROFESSIONALS ONLY.
READ BOTH THIS MANUAL AND THE OWNERS MANUAL
COMPLETELY BEFORE BEGINNING THE INSTALLATION
6. Mount all components in such a way that
they do not impair or interfere with the
normal operation of the car’s moving
parts.
7. Mount all components and run all wires so
they cannot be easily reached from
underneath the vehicle.
BEFORE YOU START, DON’T FORGET:
1. Ask the customer where to install the LED.
It should be visible from the right and left
sides of the car. It should not be exposed
to direct sunlight.
2. Ask the customer where to install the push-
button switch. It should be inconspicuous,
yet easy to reach in case of an emergency.
3. Turn the domelight OFF, or remove the
domelight fuse, to save car battery power
during the installation. (But turn the
domelight ON or replace the fuse before
testing using current sensing.)
1. Make sure all electrical connections are
securely soldered.
2. Do not run wires too tightly. Allow some
slack in case the wires are accidentally
pulled by someone servicing the vehicle in
the future. Remember that wires may
shrink or break due to impact, heat, and
so on.
3. Do not allow wires to rub against sharp
edges which could cause short circuits.
Use grommets when wires are run
through holes in the car body or firewall.
4. Protect and hide wires with flexible tubing
or by wrapping with electrical tape if
possible. Ideally, the wires should be
indistinguishable from the vehicle’s factory
wiring.
5. Mount all plastic components away from
sources of extreme heat such as the
exhaust manifold or turbocharger to
prevent melting. Also mount all
components away from areas that receive
water directly.

Function of the purple wire
See current sensing notes before use
The Enforcer 300C/300L is programmed via eight DIP switches on the alarm brain.
The various functions are programmed by turning the DIP switches on and off with a pointed
object such as an awl. Refer to Table 1 to see which functions are controlled by which DIP
switches.
Table 1 — Chart of DIP switch programming functions:
The alarm’s main brain, which controls all the
alarm’s functions, is very sophisticated, and
care must be taken when mounting. Note:
A. DO NOT MOUNT THE ALARM BRAIN
UNTIL ALL CONNECTIONS HAVE BEEN
MADE AND THOROUGHLY TESTED.
B. Do not mount the alarm brain where it is
exposed to extreme heat or moisture. DO
NOT MOUNT IT IN THE ENGINE
COMPARTMENT.
C. Mount the alarm brain out-of-sight under
the dashboard. Securely tie-wrap it in
place so it cannot be easily reached by
thieves or disconnected by accident.
D. Make sure the alarm brain does not
disrupt the normal operation of any
moving parts under the dash.
E. Do not mount in front of the heater,
defroster, or air conditioning ducts.
MOUNTING THE ALARM BRAIN
F. RF considerations — Transmitter range will
vary. For greatest range:
(1) Metal blocks RF transmission, while
glass and plastic have no effect. The
higher the alarm brain is mounted (the
closer to the windshield), and the
farther from metal, the greater the
transmitter range. Never mount in the
trunk.
(2) Do not mount near pagers, CB radios,
car horns, or air horns.
(3) Do not lengthen or cut the black
antenna wire or mount the antenna
wire to the metal car body, unless in an
area of excessive RF interference.
(4) RF interference — If there are
difficulties arming and disarming in
areas of strong RF interference, such as
near an airport or a military base, tape
the antenna wire to the car’s metal
body, or roll or fold it (do not cut it).
This may reduce range, but it should
reduce arming and disarming
difficulties.
The only difference between the two models of
the Enforcer 300 series is in the type of
transmitter used:
A. The Enforcer 300C uses SECO-LARM's
patented CODEBUMP™ code-hopping
algorithm.
DIFFERENCES BETWEEN ENFORCER 300C
AND ENFORCER 300L
B. The Enforcer 300L uses fixed code
transmitters.
NOTE — The transmitters all come pre-coded
by the factory.

1. 8-wire connector, RED WIRE (5A fuse,
to +12VDC)
Remove the 5A fuse, and connect this wire to
constant (unswitched) source of +12VDC.
Connect directly to the vehicle’s fuse box, or
to the battery (+) terminal.
IMPORTANT FOR SAFETY, DO NOT
INCREASE THE LENGTH OF THE RED WIRE.
IMPORTANT DO NOT PLUG IN THE
FUSE UNTIL ALL OTHER CONNECTIONS
ARE MADE.
2. 8-wire connector, BLACK WIRE (to
chassis ground), fig. 1
Choose a good chassis ground location. This
is the most important point of a successful
installation. A poor ground connection will
cause the siren to continuously emit a low
siren sound whenever the alarm is armed.
Use one of the car's factory bolts to connect to
chassis ground. If none is available, scrape
paint and dirt from the metal surface, and use
a grounding lug and star washer.
3. 8-wire connector, PINK WIRE
(to siren), fig. 2
A. Mount the siren under the hood to the
vehicle’s metal body. Mount as close to
the grill as possible for best sound. The
siren must not touch the engine. Mount
with the mouth facing down so water will
not collect inside the siren.
B. Connect the siren’s BLACK WIRE directly to
the vehicle’s metal chassis. Scrape paint
from the metal surface, and use a factory
grounding bolt or a star washer.
C. Connect the alarm’s PINK WIRE directly to
the siren’s RED WIRE.
4. 8-wire connector, 3 x ORANGE WIRES
(to flash pos. or neg. parking lights),
fig. 3
A. Determine if the parking lights are
positively or negatively switched — Using a
VOM meter, test the wires coming from the
parking light switch. Look for a wire which
changes polarity when the parking lights
are turned on:
(1) Positive (+) parking light system — If a
wire goes to +12VDC when the
parking lights are turned on, but is not
+12VDC with the parking lights turned
off, this is the (+) parking light wire.
(See fig. 3a)
(2) Negative (–) parking light system — If
a wire goes to ground when the
parking lights are turned on, but is not
ground with the parking lights turned
off, this is the () parking light wire.
(See fig. 3b)
(3) NOTE:
a. Most vehicles have (+) parking
light systems. A few (mainly
Japanese) have (–) parking light
systems (the (–) signal usually
triggers a relay to send +12VDC to
the parking lights).
b. If the voltage on the (+) or (–)
parking light wire varies when you
dim or brighten the interior lights,
then this is not the correct wire.

CURRENT SENSING
A. Program the alarm for switch sensing only,
or for both current & switch sensing.
B. Current sensing does not trigger the alarm
until 4 seconds after the alarm is armed.
C. If the alarm is programmed for current
sensing, but does not detect the opening
of a door, it is possible the domelights do
not draw enough current. In this case, try
a brighter domelight (check the vehicle
manufacturer’s specifications), or connect
a non-polarized capacitor (47µF or larger)
in parallel across the domelight.
D. Note regarding current sensing:
(1) If the domelight burns out or is
constantly left ON, the alarm will not
detect the doors opening.
(2) If current sensing and passive arming
are desired, connect the door pin
switches to the alarm. Otherwise the
alarm will not arm properly.

B. Connect the fused ORANGE WIRE:
(1) Positive (+) parking light system —
Connect the fused ORANGE WIRE
directly to a source of unswitched
+12VDC at the fuse box.
(2) Negative (-) parking light system —
Connect the fused ORANGE WIRE
directly to a solid chassis ground.
C. Connect 1 or 2 non-fused ORANGE
WIREs:
(1) Single-wire parking light systems —
Most vehicles have a single circuit
which controls all parking lights. In
this case, connect both non-fused
ORANGE WIREs to the (+) or (–)
parking light wire.
(2) Dual-wire parking light systems — A
few vehicles (mainly European) have
separate circuits for the parking lights
on the right and left sides of the
vehicle.
In this case, connect one non-fused
ORANGE WIRE to the right-side circuit,
and the other to the left-side circuit.
(See fig. 3c)
D. NOTE — Dual Power Protection (DPP™) —
When you connect the fused ORANGE
WIRE to +12V, it serves as a second power
source for the alarm brain in case the
fused RED WIRE is cut by thieves or
vandals. For such protection, make sure
the fused ORANGE WIRE is connected to a
separate source of +12VDC from the
fused RED WIRE.
5. 8-wire connector, BROWN/BLACK
WIRE (2nd-step door unlock negative
output)
This wire provides optional 2-step door
unlock. If used, when transmitter button #1 is
pressed one time to disarm the alarm and
unlock the doors, only the driver door unlocks.
However, if the transmitter button #1 is
pressed again within one second, all the other
doors unlock.
This wire connects to the passenger door
unlock wire via an additional relay, in most
cases. Actual connection varies from car to
car. For more information, please consult
wiring diagrams provided by the car
manufacturer or third-party references.

(2nd channel auxiliary negative
output), fig. 5
Supplies a 300mA transistor ground output
for as long as button #2 is pressed for 3
seconds, when the alarm is disarmed. For
safety, 2nd channel output operates only:
(1) If the ignition switch is OFF; or
(2) If a car door is open while the ignition
switch is ON.

(domelight neg. output), fig. 6
A. Output — Supplies a 300mA transistor
ground output, When the alarm is
disarmed, the GRAY/BLACK WIRE outputs
steady 300mA for 30 seconds, or until the
ignition key is turned ON.
B. Connection — Connect the GRAY/BLACK
WIRE via a 30A relay to the domelights.
NEVER CONNECT THE GRAY/BLACK
WIRE DIRECTLY TO THE DOMELIGHTS, AS
THIS WILL BURN OUT THE DOMELIGHT

B. Positive relay switching to factory actuators
(fig. 15) — The factory door lock switch
has 3 wires. One wire always shows
+12VDC. The LOCK WIRE becomes
+12VDC when the door is locked to pulse
a factory relay to lock the doors. The
UNLOCK WIRE becomes +12VDC when
the door is unlocked to pulse a factory
relay to unlock the doors. Most General
Motors cars use this system.
C. Positive reversal switching to factory
actuators (fig. 16) — The factory door lock
switch typically has 5 wires. Two wires
always show ground, and one always
shows +12VDC. The LOCK WIRE shows
ground at rest and during unlock, but
shows +12VDC when the door is locked.
The UNLOCK WIRE shows ground at rest
and during lock, but shows +12VDC
when the door is unlocked. Many GM
trucks, Fords, and Chryslers use this.
D. Single wire, polarity switching (fig. 17) —
The factory door lock switch uses a single
wire to control the door lock and unlock
operation. The single LOCK/UNLOCK
WIRE shows ground when the doors lock,
and +12VDC when they unlock. This is
found on most Mercedes Benz and on
some other European cars.
E. Single wire, positive shunt switching (fig.
18) — This system uses a single wire to
activate the door locks. Applying
+12VDC on the LOCK/UNLOCK WIRE
causes the doors to unlock, and removing
the +12VDC (not applying ground) causes
the doors to lock. Found on some Ford
Probes.
F. Single wire, negative shunt switching (fig.
19) — This system uses a single wire to
activate the door locks. Applying ground
on the LOCK/UNLOCK WIRE causes the
doors to unlock, and removing the ground
(not applying +12VDC) causes the doors
to lock. Found on some Mazdas and
Nissans.
NOTE Program the alarm's
door/unlock timer for 3.5-
second output (see page 17).

10. 6-wire connector, PURPLE WIRE
(positive door trigger input), fig. 6
(or to neg. external accessory, fig. 7)
This wire can be connected to positive door
triggers, or to external accessories such as
spare tires or fog lamps, but not both. See
page 17 for programming this wire.
A. Existing pos. car door switches (fig. 6) —
Use a VOM meter to locate a wire (usually
in the driver’s kick panel) which shows
+12VDC when any vehicle door is
opened, and which is not +12VDC when
all the doors are closed. Connect to the
PURPLE WIRE.
B. Externally-mounted accessory (fig. 7) —
For external accessories such as fog lights
or spare tires, make sure the accessory is
grounded. Then connect the PURPLE WIRE
to the accessory so that the wire is always
grounded. If a thief removes the
accessory, that will break the ground
connection and trigger the alarm.
11. 6-wire connector, BLUE/WHITE WIRE
(neg. hood/trunk trigger input), fig. 8
A. If the vehicle has a trunk light — Use a
VOM meter to locate a wire which shows
ground with the trunk open, and which is
not ground with the trunk closed. Mount a
pin switch in the hood. Connect as shown
in fig. 8a. Don't forget the diode.
B. If the vehicle has no existing hood or trunk
switches — Mount a pin switch in both the
hood and trunk (see fig. 8b).
12. 6-wire connector, YELLOW WIRE
(ignition switch positive input)
Connect to a fuse or wire which outputs
+12VDC when the ignition key is in the ON
and START position, but not the ACC position.
This wire must be connected at all times to
ensure proper arming and disarming, as well
as to operate the push-button switch for valet,
emergency disarm, and temporary disarm.

B. Set sensitivity:
(1) Adjusting the sensor control knob
affects both the 1st and 2nd stage
sensitivity .
(2) Test the pre-intrusion (1st stage) by
lightly shaking a set of keys once. This
should cause the siren to chirp but not
trigger. Adjust the sensitivity by turning
the adjustment knob clockwise (more
sensitive) or counter clockwise (less
sensitive).
(3) Next, test the trigger (2nd stage)
sensitivity by continuously shaking a
set of keys firmly inside the car. The
alarm should trigger.
(4) NOTE:
a. When trigger sensitivity is set to
minimum, the sensor cannot
trigger the alarm.
b. With sensitivity set to maximum,
the sensor is very sensitive.
This may cause unnecessary
chirps and/or false alarms.
c. The glass-break sensor will not
trigger the alarm until 4 seconds
after the alarm is armed.
B. If the vehicle (such as a delivery van) has
no existing car door switches — Mount a
pin switch in every door you wish to
protect. Connect each switch to the BLUE
WIRE.

These wires let the alarm control the power
door lock/unlock systems of most vehicles
without external relays. However, one or two
relays may be required in some cases.
The alarm has a built-in timer which is pre-set
for 0.7 seconds. It can be programmed for
3.5 seconds — see page 17.
Types of door lock/unlock systems — At the
time this manual was completed, there were
seven common types of power door lock/
unlock systems in use:
A. Negative relay switching to factory
actuators (fig. 14) — The factory door lock
switch has 3 wires. One wire always
shows ground. The LOCK WIRE becomes
ground when the door is locked, and
sends a pulse to a factory relay to lock the
doors. The UNLOCK WIRE becomes
ground when the door is unlocked, and
sends a pulse to a factory relay to unlock
the doors. Most Japanese cars use this
system. THIS IS THE MOST COMMON
TYPE OF POWER DOOR LOCK SYSTEM.

13. 2-wire connector, WHITE WIRES (to
starter disable), fig. 9
No external relay needed for most engines.
A. Locate the starter solenoid wire (carries
power from the ignition switch to the
starter solenoid). This wire must show
+12VDC only when the ignition is in the
start position.
B. Cut the starter solenoid wire.
C. Test the starter solenoid wire as follows:
(1) If the wire is cut before the engine is
started, the engine should not turn over.
(2) If the wire is cut while the engine is
running, it should not affect the
engine’s operation.
D. Connect the WHITE WIRE to the two halves
of the cut starter solenoid wire.
14. 2-pin RED connector, PLUG-IN LED,
fig. 10
A. Determine where to mount — The LED
should be easily seen by potential thieves
and vandals. However, do NOT mount
where the LED is easily exposed to
sunlight. Discuss the location with the
customer before mounting.
B. Drill a 1/4" hole in the LED location.
C. Run the LED connector through the hole,
and then plug into the alarm brain.
IMPORTANT DO NOT CONNECT THE
LED DIRECTLY TO THE CARS BATTERY, OR
THE LED WILL BURN OUT.
15. 2-pin WHITE connector, PLUG-IN
VELT BUTTON (push button), fig. 10
A. Determine where to mount — Location is
not important for security, as the VELT
switch cannot be used without the ignition
key. It should be hidden from view, yet
easily accessible by the user in an
emergency. IT IS IMPORTANT THE USER
EASILY REMEMBERS THE BUTTON'S
LOCATION.
B. Drill a 9/32" hole where the VELT switch
will be mounted.

Figs. 11 to 13
A. Install the included shock sensor:
(1) Cable-tie the sensor securely to at least
two points under the dash. Do not
screw it to metal. Mount so you can
reach the adjustment pods. (NOTE —
The shock sensor can be mounted at
any angle.)
(2) Plug the sensor into the alarm brain's
4-pin connector.
B. Set sensitivity:
(1) Setting the pre-intrusion stage – Turn
the red knob (secondary adjuster for
trigger output) to minimum before
adjusting the yellow knob. Now,
lightly tap the vehicle. If pre-intrusion
output is set correctly, the yellow LED
should come ON (the siren chirps &
parking light flash 5 times), but the red
LED should not. If the yellow LED does
not come on, turn the yellow pot
clockwise to increase sensitivity. To
reduce sensitivity, turn the yellow knob
counter-clockwise.
(2) Setting the trigger (2nd) stage – Hit the
vehicle hard enough to trigger the
alarm. At correct sensitivity, both
yellow and red LEDs should come on.
If not, adjust the red knob to either
increase or decrease sensitivity.
(3) NOTE:
a. When sensitivity is set to minimum,
the shock sensor is turned OFF, and
cannot trigger the alarm.
b. When sensitivity is set to
maximum, the shock sensor is
very sensitive. This may cause
unnecessary chirps and/or false
alarms.
c. The shock sensor and auxiliary
sensors will not trigger the alarm
until 4 seconds after the alarm is
armed and no further motion is
detected.
C. To connect more than one SECO-LARM
dual-stage shock, microwave, or glass
break sensor, splice the wires of the
connectors together, or use an
SR-199-315 Y-connector (fig. 12).
D. To install non-SECO-LARM auxiliary
sensors — Splice to the shock sensor's wire
harness (fig. 13). For single-stage
sensors, do not use the YELLOW WIRE.
IMPORTANT — These four wires are
transistor +12VDC or ground inputs and
outputs with max. ratings of 300mA. Take
care when connecting accessories to these
wires.
17. Jack with BLACK CABLE,
DUAL-STAGE GLASS-BREAK SENSOR
A. Install the remote microphone — Screw or
tape under the dashboard where it is out
of sight, yet can pick up the sound of glass
breaking from any of the car's windows.
Plug it into the alarm brain.
