Alarm Triggered By Interior Motion Sensor (IMS)
Function prerequisites
An alarm can be triggered by the interior motion sensor (IMS) when:
- at least one of the left or right infrared transmitter and receiver units (interior motion sensor) (A26/4, A26/5) is activated and
- the IMS function has not been switched off.
Function
The interior motion sensor (IMS) monitors the inside of the windows with infrared (IR) light with the aid of the interior motion sensor transmitter and receiver units.
The interior motion sensor transmitter and receiver unit signals a break-in attempt to the pneumatic system equipment (PSE) control module (combined) (A37) via a data bus. The PSE control module (A37) then triggers an optical and acoustic alarm.
On the T-models, the rear side windows and rear window are also monitored by glass breakage sensors.
NOTE: A maximum of three alarms in sequence can be triggered by the IMS feature.
