GF80.50-P-3014CAU Triggering Alarm With Panic Switch, Function



GF80.50-P-3014CAU Triggering Alarm With Panic Switch, Function
- with CODE (551) Anti-theft alarm system (ATA [EDW])
- with CODE (763) Radio remote control with panic switch


Function requirements, general
^ Terminal 15C OFF

Alarm triggered by panic switch, general
With the panic alarm it is possible to trigger the visual and acoustic antitheft alarm (ATA) with the transmitter key (A8/1) (e.g. in an emergency).

Function sequence when panic alarm and ATA alarm are triggered simultaneously:
The panic alarm has priority over the ATA alarm.

If both alarms are actuated the alarm with the higher priority is output and the ATA alarm is suppressed. This alarm is still actuated in the background. If one of the two alarms is terminated or is interrupted, the other is still actuated.

The alarm triggering with the panic switch comprises the following subfunctions:
^ Function sequence for actuating panic alarm
^ Function sequence for panic alarm output
^ Interrupting function sequence for panic alarm

Function sequence for actuating panic alarm
When the panic alarm button on the transmitter key is actuated for t ≥ 2 s,. it transmits a radio signal via the FM, AM and CL antenna amplifier (A2/18) (model 207.3) or FM, AM and CL antenna amplifier (A2/55) (model 207.4) to the rear SAM control unit with fuse and relay module (N10/2). This relays the signal to the electronic ignition lock control unit (N73) via the interior CAN (CAN-B). Parallel to the radio signal, an infrared signal is transmitted to the driver front door infrared remote control receiver (A26/1) (precise aiming required). This signal is read in by the left front door control unit (N69/1) and transmitted to the electronic ignition lock control unit.
In both cases the electronic ignition lock control unit checks the access authorization of the transmitter key. If the access authorization is valid, the electronic ignition lock control unit transmits the "Activate panic alarm" command to the rear SAM control unit.

It then transmits the requests for visual and acoustic alarm via interior CAN (CAN B).

Function sequence for panic alarm output
The panic alarm output comprises the following partial functions:
^ Function sequence for hazard warning system actuation
^ Function sequence for interior illumination actuation
^ Function sequence for acoustic alarm

Function sequence for hazard warning system actuation
When an ATA [EDW] alarm is triggered, the rear SAM control unit requests the hazard warning flashing function via the interior CAN. The request must be transmitted cyclically so that the flasher frequency results from the bright time and the cycle time. The front SAM control unit with fuse and relay module (N10/1) receives the request and generates a corresponding flasher frequency which is output to the interior CAN.

The following components are actuated:
- by the front SAM control unit:
- Left front turn signal lamp (E1e5)
- Right front turn signal lamp (E2e5)

- by the rear SAM control unit:
- Left rear turn signal lamp (E3e1)
- Right rear turn signal lamp (E4e1)

- by the left front door control unit:
- Left outside mirror turn signal lamp (E6/5)

- By the right front door control unit (N69/2):
- Right outside mirror turn signal lamp (E6/6)

- by the instrument cluster (A1)
- Left turn signal lamp indicator lamp (A1e1)
- Right turn signal lamp indicator lamp (A1e2)

The duration of the visual and acoustic panic alarm is the same, however, stored separated in the alarm siren (model 207.3 up to 31.5.10) and rear SAM control unit.

Function sequence for interior illumination actuation
When an ATA [EDW] alarm is triggered, the rear SAM control unit requests the activation of the interior illumination via the interior CAN. The following components of the vehicle interior illumination are actuated by the front SAM control unit:
- Right front footwell lamp (E17/15)
- Left front footwell lamp (E17/16)
- Rear interior lamp (E15/3e3) in rear dome lamp (E15/3)
- Left front interior lamp (N70/3e4) and right front interior lamp (N70/3e5) in overhead control panel electronic system (N70/3)

Function sequence for acoustic alarm
Model 207.3 up to 31.5.10:
The acoustic alarm is output by actuating the alarm siren by the rear SAM control unit with rear SAM-LIN (LIN B4).

Model 207.3 as of 1.6.10, model 207.4:
The acoustic alarm is output by the left horn (H2) and right horn (H2/1). The horns are actuated by the rear SAM control unit and horn relays (N10/1kO).

Interrupting function sequence for panic alarm
The panic alarm is interrupted when the panic alarm button on the transmitter key is actuated briefly.
The function sequence for interrupting the panic alarm is the same as for actuating the panic alarm.
