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 also  See E2510  COURTESY LIGHTS ).
