GF80.50-P-2004SK Trigger Anti-Theft Alarm, Function

GF80.50-P-2004SK Trigger Anti-Theft Alarm, Function
- with CODE (551) Anti-theft alarm system (ATA [EDW])

Component Identification:

Function prerequisites:
^ Anti-theft alarm (ATA) activated.

Alarm actuation via contact switch
If the
^ left door contact switch (S17/3),
^ right door contact switch (S17/4),
^ ATA engine hood switch (S62),
^ ATA glove compartment switch (S62/7),
^ ATA center console compartment switch (S62/8) or
^ trunk lid rotary tumbler microswitch (S88/1)
are not in their non-actuated state for longer than 0.4 s an alarm is triggered. The rear SAM control module with fuse and relay module (N10/2) initiates an acoustic and visual alarm

Alarm actuation with alarm signal horn with additional battery (H3/1)
The alarm signal horn with additional battery (H3/1) is actuated cyclically by the rear SAM control module with fuse and relay module (N10/2). If no reply is received from the alarm signal horn with additional battery (H3/1) within 1 s, an alarm is triggered. The output is only visual, since the alarm signal horn with additional battery (H3/1) cannot be actuated

If the alarm signal horn with additional battery (H3/1) detects loss of the power supply or the communication, it outputs an acoustic alarm automatically.

Alarm actuation with towing sensor (TS)
The rear SAM control module with fuse and relay module (N10/2) checks the input of the ATA inclination sensor (B33) several times per second.
If the ATA inclination sensor (B33) recognizes a position change of the vehicle, the rear SAM control module with fuse and relay module (N10/2) triggers an acoustic and visual alarm.

Alarm actuation by interior motion sensor
(with code (882b) Interior monitoring (only with ATA))
The alarm decision is made with regard to duration and speed of the motion in the passenger compartment by the interior motion sensor transmitter/receiver (A26/14).
The interior motion sensor transmitter/receiver (A26/14) transmits the corresponding signal to the overhead control panel control module (N70) via a serial interface. The overhead control panel control module (N70) relays this signal via the CAN B (CAN) to the rear SAM control module with fuse and relay module (N10/2), when then triggers an acoustic and optical alarm

Alarm memory
Triggered alarms (maximum 15) are read out in the rear SAM control module with fuse and relay module (N10/2) and central gateway control module with STAR DIAGNOSIS.

The alarm memory of the system diagnosis in the central gateway control unit offers additional information such as window and sliding roof position at the time of the ATA actuation.
