Arming the DWA

Arming the DWA

The DWA is armed from the driver's door or by the Remote Control when the vehicle is double-locked. The DWA is armed as soon as the locked status sent by the CAS over the KCAN-S is confirmed. The following phases are involved:

Immediately after arming:

- The emergency siren is armed and monitors its voltage supply.
- The DWA commences line monitoring on the local DWA K bus.

3 Seconds after arming:

- Each of the door and lid contacts to be monitored is included in the alarm table after having been in the rest position for 3 seconds.
- Faulty contacts are evaluated as closed, but are not included in the alarm table.

3 seconds after double-locking the vehicle or after locking the last door or lid:

- The referencing phase of the tilt sensor and interior sensor starts.
- The sensitivity level is set depending on the window and sunroof position.
- If the trunk lid is opened during the referencing phase, the referencing phase is interrupted and re-started after the trunk lid is locked.

20 seconds after locking the last door or lid:

- The interior sensor is included in the alarm table when its referencing period is completed.

30 seconds after locking the last door or lid:

- The tilt sensor is included in the alarm table when its referencing period is completed.
- If no acknowledgement telegram is received from the tilt sensor within 60 s of arming, this signal is deleted.
- If at least one input signal is not in idle state or if a sensor is defective, this is signalled by the flashing LED.

Deactivation of the Tilt Sensor and Interior Sensor

The interior sensor and the tilt sensor can be deactivated to prevent the alarm from being triggered by the tilt sensor during transportation by ship or train when the anti-theft alarm system is armed.

It also helps to prevent animals left in the vehicle from triggering the alarm via the interior sensor. This can be done by again double-locking the vehicle within 10 seconds of arming the vehicle.

The LED comes on for 1s to acknowledge the deactivation. It is possible to deactivate the tilt sensor and the interior sensor using VKM.
