Transmitter Functions
The receiver uses a computer-based Learn Routine to learn the
transmitter buttons. This makes it possible to assign different
transmitter buttons to different receiver functions. The transmitter
initially comes programmed with Standard Configuration, but may
also be customized by an authorized dealer. The buttons indicated
in the instructions in this manual correspond to a Standard
Configuration transmitter.

Using Your System
The transmitter buttons indicated in this guide correspond to the
standard transmitter configuration. Remember, this is not the only
way your transmitter may be set up.
You can activate, or arm, the system by pressing on your
transmitter for one second. When the system arms, you will hear a
short siren sound, or chirp, and see the lights flash once.
While the system is armed, the status LED will flash approximately
once per second, showing that the system is actively protecting
your vehicle. If you hear a second chirp after arming and see the
status LED flashing in groups, refer to the Diagnostics section of
this guide. This extra chirp is called Bypass Notification.
The system also can be programmed to arm itself automatically
(called passive arming). If the system is programmed for passive
arming, it will automatically arm 30 seconds after the ignition is
turned off. Whenever the system is in its 30-second passive-
arming countdown, the status LED will flash twice as fast as it
does when the system is armed. At the 30-second point, the siren
will chirp to indicate that the system is armed.
NOTE: Some faulty zones may prevent the system from passively arming.
(See Arming Diagnostics and Table of Zones sections of this guide.)
Additionally, each time a sensor is triggered during the passive arming
countdown, the 30-second countdown starts over.
Arming

7
©2001 Directed Electronics, Inc.
When armed, your vehicle is protected in the following ways:
■Light impacts will trigger the Warn Away®signal. When
triggered, the siren will chirp and the parking lights will flash
for a few seconds.
■Heavy impacts will trigger the system. The full trigger
sequence is 30 or 60 seconds of constant siren and flashing
parking lights.
■If the tilt switch is triggered or the ignition is turned on while
the system is armed, the full trigger sequence will activate.
■The starter kill prevents the vehicle’s starter from cranking.
Multi-Level Security is a feature that is only available when using
a Standard Configuration transmitter (see Transmitter Functions
section of this guide). Multi-Level Security Arming allows you to
select which of the security system's inputs or sensors will be
active and which will be bypassed at the time that the system is
armed (see Table of Zones section of this guide). Pressing
again within five seconds of arming the security system will acti-
vate the Multi-Level Security Arming feature. Each time is
pressed again, a different security level is selected. The different
security levels can be selected as follows:
■Pressing one time: The siren chirps once. The system is
armed.
■Pressing a second time within five seconds: The siren
chirps twice followed by a long chirp. Zone Two is now bypassed.
Multi-Level Security Arming

8©2001 Directed Electronics, Inc.
■Pressing a third time within five seconds: The siren
chirps three times followed by a long chirp. Zone Four is now
bypassed.
■Pressing a fourth time within five seconds: The siren
chirps four times followed by a long chirp. Zones Two and
Four are now bypassed.
■Pressing a fifth time within five seconds: The siren
chirps five times followed by a long chirp. All input zones,
except the ignition (Zone 5), are now bypassed.
NOTE: For watercraft, we recommend turning off the shock sensor (Zone
Two) whenever the craft is in the water to avoid false triggers.
NOTE: Multi-Level Security Arming only applies to a single arming cycle.
Once the system is disarmed and then re-armed, all the zones will be
active again.
To disarm the system, press . You will hear two chirps, and the
lights will flash twice. If the siren chirps either four or five times
when disarming, refer to the Diagnostics section of this guide.
This is called Tamper Alert.
This feature allows you to disarm the system without the transmit-
ter should it be lost, damaged or disabled. In order to disarm
without a transmitter, you must have the ignition key and know
where the Valet®switch is located. Be sure to check with the
installer for the location of the Valet switch.

To disarm the security system,
turn the ignition to the "on"
position. Press the Valet switch
the selected number of times (1-5
presses) within 15 seconds. The system should now disarm. If it
does not, you may have waited too long to press the Valet switch;
turn the ignition off and on and try again.
LOCATION OF VALET SWITCH______________________________
IMPORTANT! The unit can be programmed to respond to 1-5 pulses of
the Valet®switch for the disarm function. Be sure to check with the
installer for the desired programming.
If the vehicle battery has been disconnected or is low on power,
the back-up battery siren will sound.
Disabling and Re-Enabling the Back-Up Battery Siren
DRW-35

10 ©2001 Directed Electronics, Inc.
To disable the back-up battery siren, follow these steps:
1. Locate the back-up battery siren.
2. Remove the water protective cap on the
back side of the siren to expose the siren
lock switch.
3. Insert the siren key into the siren lock
switch and turn the key to the LEFT to
disable the back-up battery siren.
Once the vehicle battery has been reconnected or full charge is
restored, the back-up battery siren can be re-enabled.
To re-enable the back-up battery siren, follow these steps:
1. Turn the siren key back to the RIGHT.
2. Replace the water protective cap on the
back side of the siren.
WARNING! If the siren lock switch key is turned to
the enable position without the vehicle battery
being connected, the back-up battery siren will
sound.
If you are threatened in or near your vehicle, you can attract
attention by triggering the system with your transmitter! Just
press for 1.5 seconds, and you will enter Panic Mode. The
siren will sound and the parking lights will flash for the pro-
grammed siren duration. To stop Panic Mode at any time, press
on the remote transmitter again.
Panic Mode

11
©2001 Directed Electronics, Inc.
You can prevent your security system from automatically arming
and triggering by using Valet®Mode. This is very useful when
washing or servicing the vehicle. In Valet Mode, the security sys-
tem will not arm, even with the remote transmitter, but all con-
venience functions will continue to operate normally.
To enter or exit Valet®Mode with the Valet switch:
1. Turn the ignition on.
2. Turn the ignition off.
3. Press and release the Valet
switch within 10 seconds.
The status LED will light solidly
if you are entering Valet Mode, and it will go out if you are exit-
ing Valet Mode.
Your system has DEI®’s Nuisance Prevention®Circuitry (NPC®). It
prevents annoying repetitive trigger sequences due to faulty sen-
sors or environmental conditions such as thunder, jackhammers,
airport noise, etc. Here’s how it works:
The alarm triggers three times. Each time, the same shock sensor
or switch is triggering the alarm. The three triggers are within 60
minutes of each other. NPC will interpret this pattern of triggers
as false alarms. After the third trigger, NPC ignores, or bypasses,
Nuisance Prevention®Circuitry
DRW-35
Valet®Mode

12 ©2001 Directed Electronics, Inc.
that sensor or switch (along with any other sensors or switches
sharing the same zone) for 60 minutes.
If the bypassed sensor tries to trigger the system while it is being
bypassed, the 60-minute bypass period will start over. This ensures
that a sensor that continually triggers will remain bypassed.
The mercury tilt switch, the optional luggage carrier/saddlebag
protector, and the ignition switch (Zones 1, 3 and 5, see Table of
Zones section) are protected differently by NPC. If any one of
these zones is triggered for three, full 30-second cycles (one and
one half minutes), the system will bypass the zone until the
trigger ceases.
NOTE: Arming and disarming the system does not reset this function!
The only ways to reset a bypassed zone are for it to not trigger for 60
minutes, or to turn on the ignition. If testing your system, it is
important to remember that the NPC programming can cause zones to be
bypassed and appear to stop working. If five chirps are heard when dis-
arming, NPC has been engaged. If you wish to clear the NPC™
memory, turn the ignition key on.
Diagnostics
The microprocessor at the heart of your system is constantly mon-
itoring all of the switches and sensors that are connected to it. It
detects any faulty switches and sensors and prevents them from
disabling the entire system. The microprocessor will also record
and report any triggers that occurred during your absence.

13
©2001 Directed Electronics, Inc.
If the system is armed while an input is active (e.g. sensor trig-
gering) the unit will chirp once when arming and then one more
time a few seconds later. This is called Bypass Notification.
The security system will ignore the input that was active when the
system was armed, until the input goes away. Three seconds later
the system will monitor that input normally. For example, if the
tilt switch (motorcycles only) is at an unusual angle, and you try
to arm the system, you may hear Bypass Notification chirps. Once
the tilt switch is restored to its proper angle, the vehicle will be
monitored normally.
NOTE: Bypass Notification will not occur if the chirps have been pro-
grammed OFF.
Extra disarm chirps are the Tamper Alert. If four chirps are heard
when disarming, the security system was triggered in your
absence. If five chirps are heard, a zone was triggered so many
times that Nuisance Prevention®Circuitry has bypassed that zone.
In either case, the status LED will indicate which zone was
involved (see Table of Zones section). The system will retain this
information in its memory, and continue to chirp four or five times
each time it is disarmed, until the next time the ignition key is
turned on.

The zone number is the number of LED flashes used by the
security system to identify a specific input. The standard input
assignments are listed in the following Table of Zones, along with
spaces to write in any optional sensors or switches you have
had installed.

If the Warn Away®response is triggered, the LED will not report it.
Code-Hopping®
The receiver and transmitters each use a mathematical formula
called an algorithm to change their code each time the transmitter
is used. This technology has been developed to increase the secu-
rity of the unit. The control unit knows what the next codes should
be. This helps to keep the transmitter "in sync" with the control
unit even if you use the remote control out of range of the vehicle.
Table of Zones

15
©2001 Directed Electronics, Inc.
However, if the transmitter buttons have been pressed many times
out of range of the vehicle, or the battery has been removed, it
may get out of sync with the control unit and fail to operate the
system. To re-sync the remote control simply press on the
transmitter several times within range of the receiver. The alarm
will automatically re-sync and respond to the transmitters normally.
Rapid Resume Logic
This DEI®system will store its current state to non-volatile
memory. If power is lost and then reconnected the system will
recall the stored state from memory. This means if the unit is in
Valet®Mode and the battery is disconnected for any reason, such
as for a service visit, when the battery is reconnected the unit will
still be in Valet Mode. This applies to all states of the system
including arm, disarm, and Valet Mode.
High Frequency
Your system transmits and receives at 434 MHz. This provides a
cleaner spectrum with less interference and a more stable signal.
Enjoy a phenomenal increase in range – even in areas with high
radio interference.

16 ©2001 Directed Electronics, Inc.
Power Saver Mode
Your system will automatically enter Power Saver Mode while
armed or in Valet Mode, after a period of time in which no opera-
tion has been performed. This lowers the current draw on the
vehicle's battery and prevents the system from draining the bat-
tery. Power Saver Mode takes over under the following conditions:
■Power Saver when the system is armed: After the system has
been armed for 24 hours, the LED will flash at half its normal
rate, decreasing the system's current draw.
■Power Saver in Valet Mode: When the system enters Valet
Mode the LED illuminates steadily. If the vehicle is not used
(ignition is not turned on) for a period of one hour while the
system is in Valet Mode, the LED will shut off. If the system
remains in Valet Mode, the LED will come back on the next
time the ignition is turned on and then back off.

Programming Options
Programming options control what your system does during
normal operation, and require few or no additional parts. However,
some programming options may require additional installation
labor.
The following is a list of the program settings, with the factory
settings in Bold:
■Active arming (only with the transmitter) or passive arming
(automatic arming 30 seconds after the ignition is turned
off).
■Arming/disarming confirmation siren chirps on or off.
■Siren duration can be programmed for either 30 or 60
seconds.
■Siren output can be programmed for constant or pulsed
output when the system is triggered.
■Valet pulse count: The number of presses of the Valet®switch
required to disarm the security system can be programmed
from 1-5 presses. The default setting is one press.
