Movement Sensor

Information and verification, alarm

Symptom and function description
All alarm inputs are continuously monitored when the alarm is activated. The alarm is activated by pressing the LOCK button. A long flashing signal, from the vehicle's direction indicators, confirms that the alarm is activated and that the doors are locked. The alarm LED will start to flash directly after the system has been activated.
The alarm should trip when:
- Door, bonnet or boot lid are opened.
- The ignition switch is turned with a non-approved key or subjected to force.
- Movement detected in the passenger compartment (only applies if the vehicle is equipped with a movement sensor).
- The vehicle is lifted or towed away (only applies if the vehicle is equipped with a level movement sensor).
- Someone attempts to disconnect the siren or battery.
- The panic function is activated via the remote key.
The siren is used as the sound source for the alarm function. The siren includes an internal battery which is charged when the lights are on. The climate affects the life of the battery. The battery cannot be replaced as a single component. Consequently the siren should be replaced at regular intervals.

Hint: For more information, see Design and Function.

Verification
Check the different alarm system functions as follows:

Note! The alarm must not trip during testing. If the alarm goes off it should be possible to deactivate using the remote key's unlock button or by putting the remote key in the starter switch. A signal confirming alarm deactivation must be given by the direction indicators (two short flashes).

Testing the movement sensor
- Sit in the vehicle.
- Deactivate the movement sensor, then activate the alarm.
- Wait 30 seconds. Without moving.
- Test the movement senor in the passenger compartment by moving.

Testing the function of the indicator LED
- Check the LED status before and after alarm activation and with the ignition switched on.
Interpret LED indication flashing as follows:
- Unlit LED, indicates that the alarm is deactivated
- The LED flashes rapidly, after the alarm has been deactivated, up until the ignition is switched on. Indicates that the alarm has been tripped.
- The LED flashes once per second after the vehicle's direction indicators have produced one long flashing signal. Flashing indicates that the alarm is activated.
