Operation Manual

2) While the status LED is ON, press key 1 on the remote, the LED will turn off at once, reflecting
the activation of the GARAGE function.
To deactivate the GARAGE function, it is sufficient to connect the alarm system with the remote.
Using the electronic key, to turn on and off the alarm system, does not reset the GARAGE function.
Learning Remote Codes
The system can learn up to 8 control devices from among the remotes and electronic keys and
contacts by radio.
If the peripheral devices of the security system have been properly connected (DOOR pushbutton
and BONNET pushbutton), the codes can be learned without intervening directly on the alarm
control unit. This simplifies operations and reduces intervention time.
NOTE: To activate the user/installer learning procedure, the security system must be deactivated by
means of a remote or an electronic key, or by entering the emergency PIN-CODE. Moreover, the
PASSIVE ALARM ACTIVATION procedure must not have been activated.
If the system is in the PASSIVE ALARM ACTIVATION procedure, you must turn the system on and
off with a working remote or electronic key (or wait for the passive activation to end, and then
deactivate the system by entering the emergency PIN-CODE).
ACTIVATING THE LEARNING PROCEDURE:
1) Open, the driver’s side door and keep it open.
2) Open the bonnet and keep it open (obviously the protection pushbutton must be connected to
the alarm system).
3) Turn the ignition key to the ON position.
4) Press a previously learned remote key or put an already memorized electronic key into the
appropriate socket.
The system will signal entry into the learning function procedure by emitting a visual signal
consisting of two slow flashes of the turn indicators.
5) Press one of the two keys on the remote to be learned, or enter the new key to be memorized
into the appropriate slot. The system will confirm the memorization of the device by emitting a
visual signal consisting of one flash of the status LED.
6) Perform step 5) for all the devices to be memorised (remember: the maximum is 8).
DEACTIVATING THE LEARNING FUNCTION:
To end the learning function (after step 6), it is necessary to close the car DOOR and the BONNET
and turn the ignition key to the OFF position. The system will signal the exit from the learning
procedure by emitting a visual signal consisting of one flash of the turn indicators.
NOTE : THE 7503 ALARM SYSTEM DOES NOT ALLOW DELETION OF MEMORIZED DEVICES.
RELEASE PIN-CODE.
The alarm system being described here has a RELEASE PIN-CODE function which allows the user
to turn off the protection device (alarm and/or engine immobilizer) if supplied remotes do not work or
have been lost.
The PIN-CODE provided is made up of four digits from 1 to 9 set at the factory (1-1-1-1). The code
can be personalized by the user by using a “protected” programming procedure activated by means
of a working remote and the car ignition key.
RELEASING THE SYSTEM BY MEANS OF THE PIN-CODE
In order to release the system by means of the PIN-CODE, it is obviously necessary for the
protection device to be in the condition of full activation, i.e. alarm providing surveillance after the
initial neutral time or passive engine immobilizer activated.
In addition to knowing the exact digits of the PIN-CODE, the user must have the car ignition key.
DEACTIVATING THE ALARM:
In this situation it is necessary for the user to get into the car to cause an alarm condition. At the
end of the alarm cycle (lasting approx. 30”), the system will be in the neutral time between
successive alarms (duration approx. 5” – status LED emitting a continuous light). To activate the
release procedure during this phase it is necessary to turn the ignition key to the ON position and
then to the OFF position within approx. 3 seconds.
At the end of this operation, the status LED will turn off and the release procedure by means of the
PIN-CODE can be started.
ATTENTION: if the ignition key remains in the ON position for more than three seconds during the
neutral time between alarms, the system will interpret this situation as an attempted theft and
therefore a new visual/audio alarm cycle will start.
Once the release procedure has begun (i.e. when the ignition key returns to the OFF position), there
will be a pause of approx. 4 seconds, after which the status LED will emit an initial sequence of 9
flashes according to the following timing scheme: 0.5” ON – 1” OFF.
Each of these flashes can represent the number of the first digit of the release PIN-CODE. In other
words:
1st FLASH Ü NUMBER OF 1st DIGIT
2nd FLASH Ü NUMBER OF 2nd DIGIT
3rd FLASH Ü NUMBER OF 3rd DIGIT
4th FLASH Ü NUMBER OF 4th DIGIT
5th FLASH Ü NUMBER OF 5th DIGIT
6th FLASH Ü NUMBER OF 6th DIGIT
7th FLASH Ü NUMBER OF 7th DIGIT
8th FLASH Ü VALUE OF DIGIT 8
9th FLASH Ü VALUE OF DIGIT 9
To exemplify: let us suppose the PIN-CODE for the system is 4-3-2-1.
To enter the first digit (4), turn the ignition key to the ON position for at least one second during the
fourth flash of the status LED, or press the pushbutton on the LED (if LED art. 2324 is used) for at
least one second. This way the first digit (4) will be entered and after a pause of four seconds a new
sequence of nine flashes of the status LED will occur and it will be possible to enter the second digit
of the PIN-CODE (3). As in the procedure to enter the first digit, all you have to do to enter the
second digit is turn the ignition key to the ON position for at least one second during the third flash of
the status LED or press the pushbutton on the LED (if LED art. 2324 is used) for at least one
second.
And so on for the remaining two digits (2 and 1).
After entering the fourth digit, the alarm system will be released / deactivated and the set visual
signals will be emitted. Release by means of the PIN-CODE deactivates the ANTI-DISTRACTION
and PASSIVE ACTIVATION OF THE ENGINE IMMOBILIZER functions. These functions will be
reset upon the first system activation by remote.
In this case the system is not deactivated and the entire procedure must be repeated to attempt a
new release.
If during one of the four sequences of nine flashes no digit is confirmed (“0”), at the end of the ninth
flash the system will return to the normal surveillance cycle. In this case too, the entire procedure
must be repeated in order to attempt a new release.
PERSONALIZING THE PIN-CODE.
As mentioned above, the PIN-CODE is set at the factory with the following digits: 1-1-1-1. These
numbers are the same for all the alarms produced. Therefore the car user must personalize the
release code.
This operation can be performed as follows:
a) Deactivate the alarm system by means of a remote or an electronic key.
