Functional description

The alarm system is controlled by alarm control unit M30 integral with the siren. The control unit is supplied directly by the battery at pin 3 of connector A from the line protected by fuse F10 and at pin 7 of connector B (supply for the direction indicators) from the line protected by fuse F9 ; both fuses are located in junction unit B1 . The supply controlled by the ignition (INT) reaches pin 12 of connector B of control unit M30 through a line protected by fuse F1 of control unit B1 . Pin 9 of connector A is earthed. Control unit M30 controls door closure via switches N50 , N55 , N51 , N56 , which send an earth signal to pins 8, 15, 9 and 16 of connector B respectively when the door is open (the same switches light up the timed lights:  See E2510  COURTESY LIGHTS ). The bonnet lid is controlled by switch I10 , which is connected to pin 18 of connector B, while the boot lid is controlled by switch I11 , which is connected to pin 17 of connector B (the same switch turns on the boot light:  See E2520  GLOVE COMPARTMENT LIGHT - LUGGAGE COMPARTMENT LIGHT - SUN VISOR LIGHT ). Pin 13 of connector B supplies the emergency switch H70 which sends the ON and OFF signals to pins 7 and 4, respectively of connector A. Pin 1 of connector A of M30 sends alarm led control signal E40 . The left volumetric sensor ( K60 ) and the right volumetric sensor ( K61 ), receive a supply and earth from pins 8 and 11, respectively, of connector A of M30 and send the alarm control signal to pin 12 of connector of M30 . Pins 1 and 2 of connector B of M30 produce control signals for turn signals (  See E2020  DIRECTION INDICATORS / HAZARD WARNING LIGHTS ). The receiver for the remote control M35 is supplied directly by the attery at pin 3 from the line protected by fuse F10 and at pin 7 from the line protected by fuse
