Electrical (Alarm Reset): Description and operation

Alarm Reset

When the alarm has been activated, it can be silenced with the ignition off by either disarming or repeat arming using the vehicle key or the remote handset.

Battery Backed-Up Sounder (BBUS)

The BBUS is market selectable and, when fitted, is located in the driver’s side wing above the wheel arch liner, near the side repeater flasher. The BBUS provides all security alarm and miss-lock warning sounds. In the event of tampering with the BBUS, power loss will sound the alarm and the BBUS can only be silenced by reconnection to the power supply and a disarm and arm request made with the vehicle key or remote handset.

If the BBUS is disconnected with the alarm activated, the BBUS will sound. The BBUS can be removed with the alarm deactivated without sounding. The battery life of the BBUS is approximately three years, after which, replacement is recommended.

Emergency Key Access (EKA)

The EKA feature permits an armed vehicle to be fully disarmed using the key. This feature is useful if the remote handset is not available or is inoperative.

When the vehicle has been locked using the key or the remote handset, unlocking and disarming of the alarm system is normally achieved by means of the remote handset. If the remote handset is not available or inoperative, access to the vehicle can be obtained by unlocking the driver’s door with the vehicle key which initiates the EKA status.

When the vehicle enters the EKA state, the following occurs:

• The driver’s door unlocks (other doors remain in their locked condition)
• The alarm LED continues to slow flash
• Perimetric protection is suspended on all panels, except the bonnet
• Engine immobilisation and crank disable remain activated
• Volumetric protection is deactivated.

EKA requires the entry of a four number code in the CCU. The code is randomly generated and is not connected with the VIN. Each number in the code can be between 1 and 15. The EKA code is entered by turning the key in the driver’s door lock to the lock and unlock positions in accordance with the code.

If the EKA code, for example is 3, 6, 2 and 11, the following procedure would be required to fully unlock and disarm the vehicle:

NOTE: When entering the code, unlocking and locking will operate as normal on the first turn of the key. The procedure starts with the vehicle in the locked condition and the first turn to the unlock position initiates the EKA state.

• Turn the key once to the unlock position and wait for a minimum of six minutes before proceeding to enter the EKA code
• Turn the key to the unlock position three times
• Turn the key to the lock position six times
• Turn the key to the unlock position two times
• Turn the key to the lock position eleven times
• Finally, turn the key to the unlock position once.

If the code is entered correctly, the CCU will unlock all doors, fully disarm the alarm and mobilise the ignition and starter relay circuits. If the code is entered incorrectly, the vehicle will remain in the EKA state. Three incorrect attempts at code entry will result in the CCU initialising a thirty minute time out period. The CCU will fail to respond to any further code entry attempt during this period.

If a code is entered incorrectly, the system can be reset by opening and closing the driver’s door or turning the ignition on and off. An aborted attempt will not count on the CCU’s tally of incorrect attempts.
