5 Series E60 525xd (M57T2) SAL
The siren with integrate tilt alarm sensor (SINE) emits the acoustic DWA alarm. The DWA control unit activates
the siren via a single-wire bus. In addition to the DWA alarm, the siren can also emit an acoustic confirmation
signal when the system is primed or disarmed (can be set on the Central Information Display and controller).

DWA LED
The DWA LED is located on the underside of the interior mirror.
The DWA LED provides a visual indication of the status of the alarm system. The DWA LED is directly actuated
by the DWA control unit via a wire. The following displays are possible:
•
DWA LED off: DWA is disarmed.
•
DWA LED flashes (frequency = 0.5 Hz): DWA is primed.
•
DWA LED flashes with a frequency of 2 Hz for 10 seconds and then continues with a frequency of 0.5 Hz:
DWA is primed but a door or hatch is not closed or a sensor is defective.
•
DWA LED flashes with a frequency of 2 Hz for 5 minutes and then continues with a frequency of 0.5 Hz:
alarm is triggered.
•
DWA LED lights up for 2 seconds and then flashes with a frequency of 0.5 Hz: the ultrasonic interior
motion sensor and the tilt alarm sensor are deactivated.
System functions
The anti-theft alarm system incorporates the following functions:
-
Priming/disarming
-
DWA alarm triggering (alarm-trigger signal)
-
Automatic adaptation of sensitivity of ultrasonic interior motion sensor
-
Deactivating interior motion sensor and tilt alarm sensor
-
Emergency function for acoustic DWA alarm
-
Combined operation with lock cylinder and remote control
Priming/disarming
The anti-theft alarm system is primed when the central locking is locked/deadlocked. Locking/deadlocking
requires:
The driver's door to be opened and closed after terminal 15 is switched OFF.
The DWA control unit transmits the "Prime" message to the siren with integrated tilt alarm sensor (SINE) via the
local data bus. The siren is then immediately primed. 3 seconds after being primed, the door and hatch
contacts are monitored. The condition for this is that the contacts have idle status (doors and tailgate / rear
window on E61 closed).
The DWA LED starts flashing and the hazard warning lights flash once as a visual confirmation. Depending on
the national version, a short acoustic warning tone may also sound from the siren (see national version).
After the DWA has been primed and all doors and hatches are closed (including the rear window on the E61):
The ultrasonic interior motion sensor starts to map out the interior by means of ultrasonic waves. The interior can
be monitored after approx. 20 seconds.
The monitoring of the interior is interrupted if the side windows and/or the sliding/tilting sunroof are closed using
the convenience closing function.
Like the interior monitoring, the tilt monitoring does not start until the doors and hatches are closed. When it is
activated, the tilt alarm sensor first conducts a 30 second long calibration sequence. Tilt monitoring does not
start until the calibration sequence has been completed.
If the luggage compartment is opened during the calibration sequence, the calibration sequence is interrupted.
