TROUBLESHOOTING GUIDE

See page 19 for testing tips.

SITUATION

Poor transmitter range.

Transmitter LED doesnt 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.

NOTICE

The information and specifications printed in this manual are current at the time of publication.

However, the SECO-LARM policy is one of continual development and improvement. For this

reason, SECO-LARM reserves the right to change specifications without notice. SECO-LARM is

reproduced or copied, in whole or in part, without the written permission of SECO-LARM. This

vehicle security system is protected by patents in the U.S.A., Great Britain, Germany, Hungary,

Taiwan, China, Japan, and Korea. Other U.S.A. and international patents are pending.

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

which is not ground when all the doors are

closed. Connect to the BLUE WIRE.

6. 8-wire connector, BROWN/WHITE

WIRE (3rd channel auxiliary negative

output), fig. 4

A. Operation — Outputs 300mA transistor

ground for as long as button #3 is

pressed, whether the alarm is armed or

not.

B. Connection — Connect the BROWN/

WHITE WIRE to a 30A relay to control a

trunk release or other accessory. NEVER

CONNECT THE BROWN/WHITE WIRE

DIRECTLY TO AN OPTIONAL

ACCESSORY, AS THIS WILL BURN OUT

THE 3RD CHANNEL OUTPUT, AND

POSSIBLY THE ENTIRE ALARM BRAIN.

7. 6-wire connector, BLACK/WHITE WIRE

(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.

8. 6-wire connector, GRAY/BLACK WIRE

(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

OUTPUT, AND POSSIBLY THE ENTIRE

ALARM BRAIN.

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.

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

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 CARS 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.
