Definitions:
- Deactivated: The alarm is not activated and is not protecting the vehicle.
- Activated: The alarm is protecting the vehicle and will be triggered if there is an input signal from one of the sensors.
- Triggered: An alarm cycle has started. The siren sounds for 25 seconds and the turn signal lamps flash for approximately 5 minutes.
- Reactivated: The alarm has been triggered and an alarm cycle has been completed. If a check of the sensors in the vehicle shows that they are OK the alarm will be reactivated.
