SYSTEM TOTAL ARMING
SYSTEM PARTIAL ARMING
Press the lock button on the vehicle original remote control
The system can be armed without activating the volumetric protection, the external sensors (infrared
wireless) and the comfort feature. To exclude these features proceed as follows:
Disarm the alarm system and turn ignition key OFF
Open the driver door, touch the override key to its receptacle, c

Exclusion is bound to each single arming cycle.
USER MANUAL
2.3 -
When passive arming is enabled, the system automatically arms approx. 60 sec. after ignition is
switched OFF and the last door is opened and closed. Arming is confirmed by a Beep (selectable
feature) and a flash of the turn indicators..
PASSIVE ARMING
When the system arms passively, interior protection and comfort output (automatic
window roll-up) are excluded.
Opening a door during the 60 sec. arming countdown will cause the procedure to
interrupt; it will resume once the door is closed.

2.9 - ALARM MEMORY
(selectable )
The LED memory allows to identify the last alarm event signaled by 5 flashes of the turn indicators and
5 Beeps feature when the system is disarmed. Turn ignition key ON, the status LED will
flash according to the last alarm detected prior to disarming (see table below).
The flash sequence is repeated 3 times; to interrupt, turn ignition key OFF.

3.0 - WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT
The present device falls within the field of application of the current WEEE Directive. The crossed-out
wheeled bin symbol on the equipment or on its packaging indicates that the product, at the end of its
useful life, must be discarded separately from other waste to allow adequate treatment and recycling.
The user must therefore take the equipment, at the end of its useful life, to an appropriate waste
collection facility.

WHITE-ORANGE wires must ALWAYS be connected if system is to operate via
the turn indicators.

If the turn indicators lock/unlock flashes are identical, connect the door lock motors.
If the turn indicators flash when unlocking via the car mechanical key, do not make this
connection.
!
To arm/disarm via the turn indicator flashes, connect the WHITE-ORANGE wire to the turn indicators.
• If arming/disarming is only activated via the turn indicators, set dip-switch N. 4 “OFF”.
• If arming/disarming is activated via the turn indicators and door lock motor unit, set dip-switch N. 4 “ON”.
8.0 - HOW TO LEARN TURN INDICATOR LOCK/UNLOCK FLASHES
In order to arm/disarm via the turn indicators, the system must learn the vehicle lock (arm) and unlock
(disarm) flashes.
Connect the WHITE-ORANGE wire to the turn indicators and proceed as follows
Disconnect the 8-pin harness connector from the 8-pin alarm connector
Turn ignition key
Connect the 8-pin harness connector to the 8-pin alarm connector; the LED will turn ON steady
urn ignition key lose all doors and press the lock button on the original remote control
When the turn indicators stop flashing, a Beep will confirm the learning of the arming flashes
Press the unlock button on the vehicle original remote control
When the turn indicators stop flashing, 2 Beeps will confirm the learning of the disarming flashes

NEGATIVE OUTPUT SELECTION (DURING ALARM) FOR HORN OR ADDITIONAL SIREN
Programmable output used to sound the siren (steady) or the horn (pulsed). (Default setting: siren)
If the vehicle’s horn is preferred, this feature changes the output from steady to pulsed, allowing the
use of the horn for the alarm’s audible responses

able below applies to the factory settings. Accessing the programming procedure will reset the
the features to their initial settings
Optical signals activated by connection to the Hazard switch ONLY turn ON during an
alarm condition.
The alarm BLUE wire must be connected to the Hazard switch. In this case, do not
connect the ORANGE wires (see chapter 6.3).
!
The procedure must be carried out entirely by scrolling from one feature to the other using either the
ignition key or the override key (see par.11.0).
If the vehicle already has optical lock/unlock signals, the turn indicator alarm flashes
should be disabled

Cycling ignition key OFF/ON disables the features while using the override touch key enables
them.ABeep or a Bop will confirm the operation and the LED will flash as indicated (par.
NB:
In both cases, the system moves on to the next feature.
Repeat the above steps to enable or disable the other features.
When the last feature is configured, in addition to the confirmation tone, 2 Bops, 1 Beep and 2
flashes of the turn indicators will confirm the end of the programming procedure.
With the alarm system disarmed, cycle ignition key ON.
