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

General function requirements
^ C. 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 is actuated on the transmitter key for t ≥2 s, it transmits a radio signal via the roof antenna module (A2/93) to the rear SAM control unit (N10/8) and then to the EIS control unit (N73).
Parallel to this radio signal, an infrared signal is sent to the left front IR receiver (precise aiming required). A26/1 This signal is read in by the left front door control unit (N69/1) and is transmitted to the EIS control unit.
In both cases, the EIS control unit checks the access authorization of the transmitter key.
If the access authorization is valid, the EIS 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.

Additional function requirements for panic alarm output
^ Panic alarm triggered

Function sequence for panic alarm output
The alarm is output by the exterior lights, interior illumination as well as the alarm siren (H3).
The acoustic alarm is output when the rear SAM control module actuates the alarm signal horn.
The interior illumination is switched on by the overhead control panel control unit (N70).
The following components of the exterior lights are actuated:
- by the front SAM control unit:
- Left front fog lamp (E5/1)
- Right front fog lamp (E5/2)

- by the rear SAM control unit:
- Left brake light, taillamp, parking light and left side marker lamp (E3e9)
- Right brake light, taillamp, parking light and left side marker lamp (E4e9)

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.
