Security (Mislock Warning): Description and operation

Mislock Warning

When the CCU enters a partial armed condition or the alarm is armed with the tail door window down, the CCU will sound a mis-lock warning. The mis-lock warning is market selectable. The mis-lock warning is sounded from either the vehicle horn for a period of 0.02 seconds or from the BBUS for a period of 0.1 seconds.

Alarm Activated

The audible and visual warning activated by the CCU when an alarm trigger is received by the CCU, is market selectable. The audible warnings can be a constant tone from the horn for a period of 30 seconds or an intermittent tone from the horn for 30 seconds, with the horn sounding for 0.5 seconds and off for 0.5 seconds. The visual warning is flashing of the hazard warning lights for 30 seconds.

When a BBUS is fitted, all alarm and miss-lock warnings will be sounded via the BBUS.

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

The BBUS is market programmable and when fitted will provide security warnings: alarm sounder and mislock.

In the event of a tamper detection i.e. power loss to the BBUS, the sounder can only be silenced with reconnection of power to the BBUS and a disarm request followed by an arm request.

In the alarm armed condition the BBUS will sound if it detects a power supply/battery disconnection. If the alarm is not armed the BBUS can be disconnected without the device sounding. Therefore, to prevent the BBUS sounding inadvertently, before any work on the vehicle which requires battery disconnection is carried out, ensure the alarm is not armed.

It is recommended that the BBUS is changed after three years due to limits of battery life.

Remote Handset (RF Transmitter)

Two remote handsets are supplied with each vehicle. Two buttons on the handset control the locking and unlocking and alarm arm and disarm functions remotely. The remote handset transmits a coded signal which is recognized by the RF receiver. If the handset battery is removed or changed, or the vehicle battery is disconnected, the synchronization of the handset and the RF receiver will be lost.

Remote Handset Re-synchronization Re-synchronization can be achieved using the handset by operating either handset button five times in quick succession with the ignition off.

Remote Handset Battery Low Warning If the remote handset battery voltage becomes low, when the handset transmits a signal to the CCU, it also transmits a low battery signal when the driver's door is opened. The CCU buzzer sounds a 10 second warning and the alarm LED flashes for 10 seconds to signify to the driver that the handset battery requires replacement. When the battery is replaced, the remote handset will require re-synchronization with the CCU.
