Pandora DXL-1700L service-security system
Immobilizer mode
This mode is enabled by default, use a phone to disable this mode (see ‘Control over system via
phone’ section). When engine is running, base unit of Pandora security system performs a search
for immobilizer tags in radio zone. If no tags were detected, LCD remote will play ‘NO TAG FOUND’
ringtone. If no radio tags were detected when the ignition is switched on, the system will block
the engine with all radio relays that were programmed into the system. Engine blocking will only
occur when motion sensor detects movement of the car. If additional analogue blocking relays were
installed, they will block the engine immediately, before or when the car starts moving, it depends
on system settings.
Antihijack mode
This mode is disabled by default, use a phone to enable this mode (see ‘Change settings via
phone’ section). Antihijack mode helps to prevent aggressive seizure of the car using delayed engine
blocking on door opening.
Every time when the engine is running on opening/closing a door, immobilizer requests response
from a remote using unique algorithm. After a door was opened while the engine is running,
if the system cannot detect a radio tag, the engine will be stopped after 1 minute (general safety
requirement). ‘ENGINE BLOCKING WARNING’ ringtone will play before blocking.
If engine blocking is performed via radio relay after warning signals are over or on new attempts
to start the engine, immobilizer will only allow the engine to start when the car is not moving, and
will block it again if it starts movement. Immobilizer will be in active mode in no more than 2 seconds
after the ignition is switched on. If the car starts moving, the immobilizer will block the engine for 15
seconds. When registered tag appears in the radio zone, blocking will be canceled and the system will
return to the normal operation.
If the engine is blocked via analog relay, engine operation will be stopped after warning signals
are over, until a registered tag appears in the radio zone or on registering movement – depending on
the settings.
Immobilizer code using original car controls
Code immobilizer is a function that allows disarming and controlling timer channels using
original car controls (button, lever or pedal). To enter immobilizer code, programmed button (lever,
pedal) should be pressed a number of times equal the digit of the code. Pauses between presses
should not exceed 1 second. Pauses more than 1 second will be interpreted as the start of next digit
input. Immobilizer code can consist max of 4 digits from 1 to 9.
After entering a correct immobilizer code, depending on the settings, either the engine blocking
will be lifted or a programmed timer channel will be activated.
Replacing immobilizer tag battery
Carefully open the cover of the tag’s battery compartment. Extract discharged battery and insert
a new one keeping in mind the correct polarity. Replacing a battery will not cause a loss of tag code
information, as authorization data is stored in the non-volatile memory of the MCU.
Carefully close the cover of the tag’s battery compartment. All elements of construction should be
rigidly locked in places. If it is so, the tag can be operated as usually.
Control over system in case of emergency
Use a phone to deactivate the system quickly. To disarm the system via a phone, call the system’s
number. When it answers, dial command
0*
. If the call is not made from the owner’s number, guest
PIN-code should be entered. Factory set guest PIN-code is
1-2-3-4
. To switch off immobilizer RF tag/
Antihijack mode, dial command
998*
(after dialing, enter individual PIN-code that is located on the
owner’s plastic card).
If the system cannot be deactivated via a phone, apply emergency disarming/switching off
immobilizer RF tag using VALET button.
Emergency disarming/switching off immobilizer using VALET button
In case you cannot disarm the system using a remote, owner’s individual PIN-code can be used.
Individual PIN-code is written on the owner’s plastic card under protective layer. Erase the protective
layer and use VALET button to input PIN-code.
1. Using VALET button, input the first digit of the code (press the button a number of times, equal
to the first digit; pauses between presses should not exceed 1 second). The system will confirm with
