ACTIVATING THE ALARM SYSTEM.
The alarm can be activated by pressing key1 on the remote or by inserting the electronic key into the
appropriate socket. The operation is confirmed by a visible signal consisting of one flash of the turn
indicators lasting approximately one second. During the flash, the following functions are enabled:
a) Module output (PINK wire / +A)
b) LED output (lit continuously to indicate neutral activation time)
c) Engine immobilizer
d) Activation of door-locking control (with the timing selected in programming phase).
If the electronic key is used, all the functions described under points a), b) and c) will be activated,
except d) ACTIVATION OF DOOR-LOCKING CONTROL which does not occur so that the user can
get out of the vehicle).
Moreover, by using the electronic key, a car entry time of approximately 10 seconds will be
generated to allow the user to get into the car and deactivate the alarm system with the electronic
key without creating a false alarm.
While the user gets into the car, entry time is indicated by the continuous light of the LED.
NEUTRAL ACTIVATION TIME – CUTTING OUT OF EXTERNAL SENSORS / STOPPING UPWARD WINDOW /
COMFORT.
Neutral activation time lasts approx. 45” and it is indicated by the continuous light of the LED. This
time interval allows the user to get out of the vehicle without causing false alarm conditions. During
the first 25” of the neutral time it is possible to cut out the external sensors and stop the windows’
upward travel by pressing key 2 on the remote (Note: the stop window function requires the
installation of a special module – see art. 2344 – or the COMFORT function fitted on the car).
CUTTING OUT THE EXTERNAL SENSORS / STOPPING WINDOW UPWARD TRAVEL / COMFORT) IS INDICATED
BY A BRIEF FLASH OF THE TURN INDICATORS.
NOTE: SENSOR CUTOUT IS LIMITED TO A SINGLE ALARM ACTIVATION CYCLE.
CUTTING OUT THE SIREN.
To cut out the sound of the siren and enable the alarm signal only through the turn indicators you
must follow this procedure:
a) With the system off, turn the ignition key to the ON position – the LED will light up for about 0.5
seconds.
b) While the LED is ON (0.5 seconds), press key 2 on the remote – the LED will immediately turn
off.
The siren will be cut out for the next alarm activation cycle. To reactivate the siren, just
deactivate and reactivate the alarm system.
SYSTEM READY AFTER NEUTRAL TIME.
At the end of the neutral time (approx. 45”), the security system is completely armed and ready to
intervene in cases of attempted theft or sabotage.
Completely armed status is indicated by the flashing of the LED, which will be piloted according to
the following timing scheme in order to minimise power consumption:
LED ON : 200MS
LED OFF : 2”
EVENTS THAT CAN GENERATE AN ALARM CONDITION:
a) Cutting of system wire.
b) Attempt to start engine.
c) power drain. (this function is active only if enabled in the accessory function programming
phase and can be used only in countries where the law does not prohibit the use of this
sensor).
d) Attempt to open the doors
e) Attempt to open boot.
f) Attempt to open engine bonnet.
g) Intrusion detected by internal ultrasound volume sensor and optional external modules (even by
radio).
h) Intrusion detected by external sensors (option) (also by radio ).
i) Panic alarm – by pressing key 2 on the remote (this function is active only if enabled in the
accessory function programming phase and it can be used only in countries where the law
permits this type of alarm activation).
NOTE: In order to filter noise and/or undesired signals, the POSITIVE POLE UNDER KEY, DOORS
PUSHBUTTON and BOOT PUSHBUTTON inputs have a DEBOUNCE time of 200mS. Therefore
these inputs will cause the generation of an alarm cycle only if the signals coming in last longer than
200mS.
ALARM CYCLE.
An alarm cycle generated by an attempt to break in consists of the activation of the sirens connected
to the alarm device (unless previously cut out) and the flashing of the turn indicators for a maximum
of 30”.
NOTE: During the alarm signal , the LED will be on.
You can cut off the alarm cycle without deactivating the system by pressing key 2 on the remote. As
you do so, the audio/visual alarm signals will be immediately cut off, and the system will switch to
the mode NEUTRAL TIME BETWEEN SUCCESSIVE ALARMS.
To minimise sound pollution in cases where the cause of the alarm persists, the DOORS
PUSHBUTTON, ELECTRICAL INPUT SENSOR, and EXTERNAL SENSORS inputs are subject to a
limitation of up to five alarm cycles per system activation period. The count is reset upon next
deactivation of the alarm system.
NOTE: THE POSITIVE POLE UNDER KEY INPUT AND THE WIRE CUT FUNCTION HAVE NO ALARM
LIMITS.
NEUTRAL TIME BETWEEN SUCCESSIVE ALARMS.
At the end of each alarm cycle there is a neutral time period, lasting up to approx. 5”, during which
there will be no reaction to the causes of alarm. During the neutral time between successive alarms,
the LED will emit a continuous light. Normal flashing will be resumed at the end of the neutral time.
DEACTIVATING THE ALARM SYSTEM.
The alarm system can be deactivated by pressing key 1 on the remote, or by inserting the electronic
key into the appropriate socket (or by means of an emergency PIN-CODE procedure during the
neutral time between successive alarms).
Following this action, the centralized door-unlocking command will be implemented at once,
according to the timing programmed at the installation phase, and two different types of confirmation
signals will be generated:
1) DEACTIVATION WITHOUT INDICATING ALARM CONDITIONS: If no theft or break-in
attempts have been detected during the surveillance period, the system will give out a visible
signal consisting of three flashes of the turn indicators.
2) DEACTIVATION WITH INDICATION OF ALARM CONDITIONS: If one or more attempted
thefts or break-ins have been detected during the surveillance period, the system will give out a
visible signal consisting of 5 flashes of the turn indicators.
WHEN THE ALARM SYSTEM IS DEACTIVATED, THE FOLLOWING OUTPUTS / FUNCTIONS ARE DISABLED:
a) MODULE OUTPUT (PINK wire / +A)
b) LED OUTPUT
c) ENGINE IMMOBILIZER function
