194001707 - E7015 ALARM - DESCRIPTION
The alarm system offers volumetric and perimeter protection against intrusion into the vehicle and protection against lifting the vehicle.A special control unit (integrated in the body computer) checks:- the state of the doors and lids, via switches in the catches (perimeter control)- the presence of a moving object inside the passenger compartment, by means of volumetric sensors. (volumetric control);- the condition of the system supply leads;- operation of the ignition switch.The control unit is equipped with a self-diagnostic function which detects and memorises faults and problems in the control unit and system components; in addition, it checks the condition of the connecting cables and saves the number of activations and times the alarm has been operated.The control unit operating logic can be modified in order to satisfy the legal requirements which govern the use of alarm systems in the various markets.For more details, See descriptions 5580E ANTI-THEFT DEVICEThe alarm siren P090 and the volumetric, perimeter and lift sensors for the alarm K062 are connected with the Body Computer by means of a dedicated serial line.For more details, See E1060 A-BUS SERIAL LINEThe volumetric, perimeter and lift sensors control that there are no intrusions in the vehicle and that nothing is removed from it.They are located in the front courtesy light: the volumetric and perimeter sensors consist of a transmitter and a receiver: the wave sent by a transmitter should reach the receiver for the other sensor and viceversa; if this is not the case, an alarm signal is sent to the control unit.The alarm siren is located at the front, under the wheel arch liner on the right of the engine compartment.The door lock system switches are used to monitor the doors and boot.A special separate switch detects bonnet closure.The function may be activated/deactivated by pressing a key next to the sensors: when the sensors are excluded, a led next to the button is turned on.The deterrent LED is located to the side of the driver''s door safety knob: it signals the "central locking" function See E3040 CENTRAL LOCKINGWith the alarm on the LED flashes at 0.8 Hz to indicate that the vehicle is locked. | The deterrent function is also activated if one or more of the doors or the boot is not properly shut. |
