for the van version, the loading platform. They send the signal indicating the status of the doors and of the bonnet to the ECU.
Door-blocker/unblocker motors
Each door has its own motor for closing/opening the lock on the door.
Operation of the motor is enabled by switching the remote-control switches on the circuit card of the ECU on/off for a
pre-established period of time, programmable in the EEPROM of the ECY.
These motors can be activated in two different ways:
- by means of the pushbutton on the remote-control key (blocking/unblocking of all the doors)
- - by means of the switch on the switch panel (blocking/unblocking of the rear door only, in the van version).
With the +15 power supply on, operation of the motors by pressing the pushbutton on the remote-control key is not possible.
Activation of the motor of the rear door by means of the switch on the switch panel is possible, on the other hand, regardless
of the presence or otherwise of the +15 power supply.

This module carries out volumetric detection inside the cab, by means of the two sensors located on the sides of the ceiling-light
(A) inside the cab, starting from when the anti-theft protection is activated. It sends the data to the ECU. Any changes in the
state inside the cab due, for example, to the windows being smashed or an object being accidentally moved, will be transmitted
to the ECU, which will command the anti-theft protection to switch on.
The module includes a LED for signalling that the anti-theft protection has been switched on. This is also mounted in the
ceiling-light inside the cab (B), and in addition to the state of the anti-theft protection (active, inactive), it also signals that key
learning has been accomplished and any failures in the system.

Siren
The siren is located inside the engine compartment. It is self-powered by an internal battery that enables it to sound when it
is disconnected from the vehicle, and it must comply with specific requisites, such as supplying a value greater than or equal to
100 dB at a distance of 1 metre from the siren after 5 minutes of operation.
The batteries of the siren are recharged in the following ways:
- trickle-charging
- rapid charging
- charging after disconnecting the siren from the vehicle
Trickle-charging is always activated in order to compensate for the normally occurring loss of charge of the batteries. The
batteries will be charged by supplying a 12 mA current for one minute at intervals of one hour.
Rapid charging takes place for a duration of 14 hours with a current of 12 mA. This method is used when the siren is connected
for the first time, or when it is reconnected to the system following maintenance operations on the vehicle that require the battery
to be disconnected. Once the required time has elapsed, charging stops. This type of charging does not require the +15 power
supply to be on.
With the third type of charging, if the siren of the vehicle is disconnected while it is not sounding, the whole time for which it
remains disconnected will be the same required to recharge the batteries when it is connected to the system again. If, on the
other hand, the siren is disconnected after it has been triggered, when it has to be reconnected to the system the batteries will
be charged for 45 seconds for each second that the siren remained disconnected. This recharging process is only carried out
with the +15 power supply off. If the batteries are below the minimum charging level, they will be recharged, with the +15 power
supply on, for 14 hours at 12 mA.
