plug-in harnesses
The super bright LED operates at 2V DC. Make sure the LED wires are not shorted to ground as the LED will be
damaged. Multiple LED’s can be used, but they must be wired in series. The LED fits into a 9/32 inch mounting
hole. Be sure to check for clearance prior to drilling the mounting hole.
The Valet
®
/Program switch should be accessible from the driver’s seat. It plugs into the blue port on the side of
the unit. Since the system features Valet
®by using the remote transmitter, the switch can be well hidden.
Consider how the switch will be used before choosing a mounting location. Check for rear clearance before drilling
a 9/32-inch hole and mounting the switch.The GRAY wire in the two-pin plug may also be used as a (+) ghost
switch input and can be connected to any (+) switch in the vehicle. (See Feature Descriptionssection of this
guide.)
The black three pin port is provided for personal computer programming of the unit. When using the DEI Bitwriter
(P/N 998T) or optional PC Interface Module (P/N 996T) it is possible to configure any and all of the program-
mable functions. The PC Interface Module works with an IBM compatible PC. (The 998T does not require the IBM
compatible PC.) For more information please refer to the guide packaged with the programmer. This port can also
be used to interface the Valet
®Car★Com (DEI P/N 820T) with the security system.

on-board dual stage shock sensor
There is a dual-stage shock sensor inside the control unit. Adjustments are made via the rotary control as indi-
cated in the diagram. Since the shock sensor does not work well when mounted firmly to metal, we do not
recommend screwing down the control module. The full trigger of the on-board shock sensor reports Zone 2. See
theTable of Zones section of this guide.
NOTE:When adjusting the sensor, it must be in the same mounting location that it will be after
the installation is completed. Adjusting the sensor and then relocating the module requires read-
justment.
optional sensor harness, 4-pin connector
The four-pin sensor harness is optional, and is not included with this unit.
These wires supply constant 12 volts and ground to the optional sensor.
These wires are multiplex inputs. If a (-) input of less than 0.8 seconds is supplied to either wire, the Warn-Away
response will occur. A (-) input of longer than 0.8 seconds to either wire will initiate the triggered sequence and
report Zone 4.

internal programming jumper
This jumper is used to determine the light flash output. In the (+) position, the on-board relay is enabled and
the unit will output (+)12V on the WHITE wire, H1/2. In the (-) position, the on-board relay is disabled. The
WHITE wire, H1/2, will supply a 200 mA (-) output suitable for driving factory parking light relays.
bypassing sensor inputs
There are times when you need to temporarily bypass all sensor inputs to the unit, such as when remote start-
ing the vehicle. Anytime an auxiliary channel output is used, all inputs are bypassed for 5 seconds. During the
5 second bypass period, ground can be supplied to the H1/6 Blue wire without triggering the unit. When the 5
second bypass period ends, if the unit sees ground on the H1/6 Blue wire, all trigger inputs except the door
trigger input will remain bypassed until 5 seconds after ground is removed from the BLUE wire. This can be done
using the status output of a 551T remote start unit as shown below:

system features learn routine
™
The System Features Learn Routine
™dictates how the unit operates. Due to the number of steps, they have been
broken up into two menus. It is possible to access and change any of the feature settings using the
Valet
®
/Program switch. However, this process can be greatly simplified by using the optional DEI Bitwriter or
Personal Computer Interface, P/N 996T. Any of the settings can be changed and then assigned to a particular
transmitter, up to four, a feature called Owner Recognition. Each time that particular transmitter is used to
disarm the system, the assigned feature settings will be recalled. Owner Recognition is only possible when pro-
gramming the unit via the 996Tor the 998TDEI Bitwriter.
Using the optional DEI Bitwriter or PC Interface, the learn routine may be locked. Make sure the learn
routine is unlocked before programming features. If the siren generates one long chirp when attempting
to program the unit, the learn routine is locked and must be unlocked using the DEI Bitwriter or PC before proceeding.
1. Open a door.(The H1/5 GREEN wire or the H1/7 VIOLET wire must be connected.)
2. Ignition. Turn the ignition on, then back off: (The H1/9 YELLOW wire must be connected.)
3. Select a Menu.Press and HOLDthe Valet
®
/Program button: (The Valet
®
/Program button
must be plugged into the blue port.) After three seconds the siren will chirp once indi-
cating entry to the Basic Features Menu #1. If this is the menu you wish to access, release
the button and go on to step 4. If the button is not released, you will jump to the
Advanced Features Menu #2 and the siren will chirp twice. Once you have selected the
desired menu, release the Valet
®
/Program button and then go to step four.
4.Select a Feature.Press and release the Valet
®
/Program button the number of times corre-
sponding to the step you wish to change. For example, to access the third feature, press
and release three times. Then press the button once more and HOLDit. The siren will chirp
the number of times equal to the step you have accessed.
5.Program the Feature.While HOLDINGthe Valet
®
/Program button, you can toggle the
feature on and off using the remote transmitter. Pressing Button I will select the one chirp
or default setting. Pressing Button II will select the two chirp setting. (See
Transmitter/Receiver Learn Routinesection of this guide.)
NOTE:The Valet
®pulse count feature (2-5) and the Channel three timed output (2-9) have five
possible settings each. Pressing channel 2 will toggle through all the possible settings.

■Other features can be programmed within the same menu.
■Another menu can be selected.
■The learn routine can be exited if programming is complete.
1.Press and release the Valet
®
/Program switch the number of times necessary to advance from the feature you
just programmed to the next one you want to program.
2.Then press the Valet
®
/Program switch once more and HOLDit.
For example, if you just programmed the third feature in the menu and you would like to program the seventh
feature in the menu, you would press and release the Valet
®
/Program switch four times and then press it once
more and HOLDit. The siren would chirp seven times to confirm access to the seventh feature.
1.Press and HOLDthe Valet
®
/Program switch.
2.After three seconds, the unit will advance to the next menu and the siren will chirp, indicating which menu
has been accessed.
For instance, if you just programmed some features in Menu #1 (Basic Features) and you desire to program a
feature in Menu #2, you press and HOLDthe Valet
®
/Program button. After three seconds, the siren chirps twice
indicating access to Menu #2.
To exit the learn routine, do one of the following:
1.Close the open door.
2. Turn the ignition on.
3. No activity for longer than 15 seconds.
4. Press the Valet

feature descriptions
The features of the system are described below. Features that have additional settings that can be selected only
when programming with the PC interface or Bitwriter are indicated by the following icon:
1-1 ACTIVE/PASSIVE ARMING:When active arming is selected, the system will only arm when the transmitter is
used. When set to passive, the system will arm automatically 30 seconds after the last door is closed. To alert
the consumer of passive arming, the siren will chirp 20 seconds after the door is closed. This provides the con-
sumer with an audible warning prior to the system actually arming. At the 30 second mark, the system will arm
but the siren will not chirp.
1-2 Chirps ON/OFF: This feature controls the chirps or voice messages (if using the 516M voice module) that
confirm the arming and disarming of the system.
1-3 IGNITION CONTROLLED DOOR LOCKS ON/OFF: When turned on, the doors will lock three seconds after
the ignition is turned on and unlock when the ignition is turned off. The TechSoft Programmeror the 998T
Bitwriter
™will display separate steps for ignition lock and ignition unlock. They can be programmed on or off inde-
pendently.
1-4 ACTIVE/PASSIVE LOCKING:If passive arming is selected in step 1-1, then the system can be programmed
to either lock the doors when passive arming occurs, or only lock the doors when the system is armed via the
transmitter. Active locking means the system will not lock the doors when it passively arms. Passive locking means
that the system will lock the doors when it passively arms.
NOTE: Remember, when passive arming is selected, the unit will chirp 20 seconds after the last door is
closed. The system does not actually arm or lock the doors until 30 seconds after the door has been closed.
1-5 PANIC WITH IGNITION ON: This step controls whether or not the Panic Mode is available with the ignition
on. In some states, there are laws prohibiting a siren from sounding in a moving vehicle. This feature makes the
system compliant with these regulations.
1-6 DOOR LOCK PULSE DURATION:Some European vehicles, such as Mercedes-Benz and Audi, require longer lock
and unlock pulses to operate the vacuum pump. Programming the system to provide 3.5 second pulses, will
accommodate the door lock interface in these vehicles. The default setting is 0.8 second door lock pulses.
1-7 FORCED PASSIVE ARMING ON/OFF:To use this feature, passive arming must be selected in step 1-1. When
turned on, forced passive arming will ensure that the system will passively arm, even if a zone is left open or
invalid. Forced passive arming occurs one hour after the ignition is turned off.
menu #1 - basic features

11 © 2000 Directed Electronics, Inc. Vista, CA
1-8 AUTOMATIC ENGINE DISABLE (AED) ON/OFF:AED is a full-time, passive starter disable that works
independently of the security system. When turned on, the orange, ground-when-armed output (H1/1) will go
active 30 seconds after the ignition is turned off. The LED will flash at half its normal rate when the ignition is
turned off to indicate that AED is active and will interrupt the starter in 30 seconds. AED does not occur in Valet
®
mode and can be bypassed using the emergency override procedure. The transmitter can be used to disarm AED;
however, the system must be armed and then disarmed with the transmitter, in order to disarm AED.
1-9 ARMED WHILE DRIVING/VEHICLE RECOVERY SYSTEM:In the default setting (Armed While Driving), the
system can be armed with the ignition on. When armed, the ground-when-armed is not active and the sensors
are bypassed. The door triggers will remain active. If programmed to the Vehicle Recovery System (VRS
®
) setting,
VRS will be activated.
1-10 CODE-HOPPING
™ON/OFF: The system uses a mathematical formula to change its code each time the trans-
mitter and receiver communicate. This makes the group of bits or “word” from the transmitter very long. The
longer the word is, the easier it is to block its transmission to the unit. Disabling the Code-Hopping
™feature lets
the receiver ignore the Code-Hopping
™part of the transmitted word. As a result, the unit may have better range
with Code-Hopping™ off.
2-1 SIREN/HORN HONK:The system can be programmed to output pulses instead of a continuous output when
the system is triggered. This is useful to honk the factory horn in applications where a siren is undesirable.
Remember that the unit is only capable of supplying 1 amp of current. A relay will be required to interface with
most factory horn systems.
2-2 SIREN DURATION 30/60 SECONDS: It is possible to program the unit to sound for 30 or 60 seconds
during the triggered sequence. Some states have laws regulating how long a security system can sound.
When using the TechSoft Programmer or Bitwriter™, the siren can be programmed to sound for any length of time
ranging from 1 to 180 seconds. Use the right and left arrows or the + and - keys on your keyboard to change the
siren duration in 1 second intervals. Holding down the key will rapidly increase or decrease the setting. The
desired siren duration can also be directly entered by using the number keys on your computer's keyboard. When
using the Bitwriter, pressing the SELECT button will adjust the siren duration.
2-3 NUISANCE PREVENTION
®CIRCUITRY (NPC™) ON/OFF:NPC™ stops repeated triggering of the same zone. If
one zone is triggered three times in one hour, that zone is bypassed for one hour, starting from the time of the
third trigger. During that hour, if the system detects a trigger on that zone again, the system resets the one hour
timer. If one hour passes and the zone has not triggered again, the zone is activated and can trigger the system
again. NPC™ only monitors sensor inputs, and does not bypass the door trigger or the ignition trigger at any time.
If NPC™ is turned off, the system will respond to repeated triggers on the sensor inputs and will do so indefi-
nitely. Some states have laws regulating how many times a security system can trigger before it is considered a
nuisance and the vehicle is towed away.
menu #2 - advanced features

© 2000 Directed Electronics, Inc. Vista, CA12
2-4 PROGRESSIVE DOOR TRIGGER ON/OFF:The system responds to a door trigger input with a progressive
response. When the door is opened with the system armed, the siren will chirp 10 times prior to the full trig-
gered sequence. The door trigger is still treated as an instant trigger and closing the door quickly will not prevent
a full triggered sequence from occurring. If the progressive door trigger is programmed off, the full siren output
will occur the moment the door is opened.
2-5 VALET PULSE COUNT 1 to 5 PULSES: The system can be programmed to count the number presses of the
valet switch before disarming the security system or VRS
®
. The factory default setting is one pulse. The unit can
be set for 2 to 5 pulses using the two-chirp setting to select the pulse count.
GHOST SWITCH OPTION:For added security, the GRAY wire on the two-pin Valet
®
/Program can be
connected to any switch in the vehicle that provides a positive (+) momentary pulse.
2-6 DOOR TRIGGER ERROR CHIRP ON/OFF: With the door trigger error chirp programmed off, the system will not
report an invalid zone on arming when the door trigger wire is active. This eliminates the extra chirps that occur
when interfacing with vehicles that have exceptionally long dome light delay circuits.
2-7 IGNITION-CONTROLLED DOMELIGHT SUPERVISION ON/OFF: If turned on, the system will turn on the dome-
light for 30 seconds when the ignition is turned off. The optional domelight supervision feature must be installed.
2-8 DOUBLE PULSE UNLOCK ON/OFF: Some vehicles require two pulses on a single wire to unlock the doors.
When the double pulse unlock feature is turned on, the BLUE H2/C wire will supply two negative pulses instead
of a single pulse. At the same time, the GREEN H2/A wire will supply two positive pulses instead of a single pulse.
This makes it possible to directly interface with double pulse vehicles without any extra parts.
2-9 CHANNEL 3 VALIDITY/LATCHED/LATCHED RESET WITH IGNITION/30 SECOND TIMED/SECOND UNLOCK
OUTPUT: Channel 3 can be programmed for these output configurations. The unit is set to the default validity
output. To change the configuration, use the two-chirp setting to toggle to the different configurations.

transmitter/receiver learn routine
™
The system comes with two transmitters that have been taught to the receiver. The receiver can store up to four
different transmitter codes in memory. Use the following learn routine to add transmitters to the system or to
change button assignments if desired.
When the learn routine has previously been programmed using an optional hand-held system programmer
(p/n 998T) or PC Interface module, it may have been locked. Before proceeding with reprogramming the
learn routine, it must be unlocked by using either p/n 998T or the PC Interface module - this cannot be done
manually with the Valet switch. If the learn routine is locked, transmitters cannot be programmed to the system.
1.Open a door. (The H1/5 GREEN wire or the H1/7 VIOLET wire must be connected.)
2.Key.Turn the ignition on. (The YELLOW wire, H1/9 must be connected.)
3. Select the receiver channel:Press and release the Valet
®
/Program button the number of
times necessary to access the desired channel.
NOTE:If adding a remote, a button must be taught to the unit in the Channel 1 or Channel 4 posi-
tion prior to programming other channels, unless programming to one of the Auto Learn
Configurations.
Press and HOLDthe Valet
®
/Program button once more. The siren will chirp and the LED will blink the number of
times corresponding to the channel that is accessed.

4. Press the transmitter button: While HOLDINGthe Valet
®
/Program switch, press the
button from the transmitter that you wish to assign to the selected channel. The unit will
chirp indicating successful programming. It is not possible to teach a transmitter button
to the system more than once.
Channels #4-6: Channels 4 through 6 are used to assign the arm, disarm and panic functions to separate buttons
on the remote control. Teaching a button to Channel 4 erases all information about that remote from memory.
Any auxiliary functions that are desired will have to be reprogrammed. Similarly, if the remote is set up to use
the separate arm, disarm and panic channels and a button from that remote is entered into channel one, the
remote will be erased from memory, and the system will only recognize the button that was entered into channel
one.
Channel #9: If any transmitter button from a known transmitter is programmed to Channel 9, all transmitters
will be erased from memory and will revert to the default feature settings (see the Features Menusection of this
guide). This is useful in cases where the one of the customer's transmitters is lost or stolen. This will erase any
lost or stolen transmitters from the system's memory. It can also be used to start from scratch if the transmitter
buttons were programmed incorrectly.
5.Release:Once the code is learned, the Valet
®
/Program button can be released.
Learn Routine™ will be exited if:
■Ignition is turned off.
■Door is closed.
■Valet
®
/Program button is pressed too many times.
■More than 15 seconds elapse between steps.
One long chirp indicates that Learn Routine™ has been exited.

transmitter configurations
Using the Auto Learn functions in the Transmitter/Receiver Learn Routine, the transmitters can be programmed
either with the standard single button arm/disarm configuration (default) or with the expanded configuration,
which requires an optional 4-button transmitter.
Your system has an expanded configuration that can be fully utilized from your four-button transmitter. In the
expanded configuration, your system will operate similarly to many factory keyless entry systems that use sepa-
rate remote transmitter buttons for the arm, disarm, panic and auxiliary output functions:
