THEFT ALARM SYSTEM

THEFT ALARM SYSTEM (EXCEPT JAPAN) Vehicle Status Indication

Vehicle status is indicated by up to three devices: (a) Alarm Sounder (Z171), (b) hazard lights, (c) Theft Alarm LED (B151). When the vehicle arms in either mode, the hazard lights will flash three times and the LED will flash rapidly for 10 seconds. LED will then flash at a slower rate while vehicle is armed. When the vehicle disarms, hazard lights will flash once and LED will extinguish. If LED remains lit, it indicates that the alarm has been triggered. Turning on ignition or arming the alarm will extinguish LED. The LED will give a long pulse flash to indicate the Alarm Sensor (X213) being activated.

Central Locking

Central Locking is controlled by the Theft Alarm Unit (Z163) and may be operated by the key, sill button(s) or handset. The system works on both front doors on four door vehicles or driver’s door on two door vehicles. NOTE: The central door locking system will shut down for a period after more than 15 consecutive operations.

Inertia Switch

An inertia switch is incorporated in the Theft Alarm Unit (Z163). If ignition is on and the vehicle receives an impact sufficient to activate the inertia switch, the unit will signal to unlock central locking actuators and flash hazard lights. Central locking will remain disabled for 30 seconds. To reset, turn ignition off and then on after the 30 second period has elapsed.

Alarm Sensor (X213)

The sensor operates by emitting an air pressure carrier wave and receiving the wave back. Any disturbace within the vehicle which disturbs the wave will be detected, triggering the alarm. When the volumetric sensor is activated it monitors movement within the vehicle for 15 seconds before detecting and responding to intrusions. If the sensor detects movement within the vehicle it delays arming until a 15 seconds quiet period has elapsed. If continuous movement is detected, the alarm will not arm volumetrically.

Radio Frequency System

The RF system uses four frequencies according to market. If the coaxial aerial is not fitted system performance will be impaired. Both ECU and handset have a colour-coded label. Frequency Colour Territory ECU/Handset: 418.0 MHz, Pink/pink: UK, Ireland 224.5 MHz, Yellow/yellow: France 433.92 MHz, Blue/blue: Europe (not France, Switzerland, Italy, Denmark) 433.92 MHz, White/blue: Switzerland, Denmark 315.0 MHz, Green/green: Rest of World, Italy, Australia 315.0 MHz, Orange/green: Gulf, Japan
