The￿alarm￿system￿in￿the￿I01￿is￿equipped￿with￿an￿ultrasonic￿interior￿movement￿detector￿for￿monitoring
the￿passenger￿compartment.￿The￿ultrasonic￿interior￿movement￿detector￿(USIS)￿is￿fully￿integrated￿in
the￿roof￿function￿center￿(FZD).
The￿door￿contacts,￿engine￿compartment￿lid￿contact￿switch￿and￿the￿opening￿of￿the￿tailgate￿are
monitored￿by￿the￿Body￿Domain￿Controller.￿As￿soon￿as￿a￿status￿changes,￿the￿ultrasonic￿interior
movement￿detector￿receives￿this￿information￿via￿the￿K-CAN2.￿In￿the￿event￿of￿an￿activated￿alarm
system￿a￿siren￿with￿tilt￿alarm￿sensor￿is￿activated￿by￿the￿control￿unit￿in￿the￿event￿of￿a￿break-in.
The￿SINE￿is￿connected￿to￿the￿FZD￿via￿a￿local￿interconnect￿network￿bus.
