ALARM SYSTEM AND HORN: DESCRIPTION AND OPERATION (page 7 of 8)

ALARM SYSTEM AND HORN

DESCRIPTION AND OPERATION 86-4-23

In order for speed related locking to activate the following conditions must be met:

l

All doors unlocked.

l

Engine running.

l

Vehicle speed greater than 4 mph (7 km/h).

Acclimatisation related locking
Acclimatisation related locking allows the engine to be started and then the vehicle locked with a spare key and left 
unattended to allow the vehicle interior to reach the desired temperature.

There are two configurations for acclimatisation related locking:

l

Acclimatisation related locking not active.

l

Acclimatisation related locking active.

Once the engine is started, the vehicle is locked with a spare key at the driver's door while the engine is running.  
During these conditions the alarm is not armed.

In order to activate acclimatisation related locking the following conditions must be met:

l

Engine running.

l

All doors closed.

Visual warnings
The direction indicators serve as a visual indication when the alarm is triggered. The direction indicators are also used 
as a visual indication during lock/unlock procedures.

There are three configurations of alarm armed/disarmed indication:

l

No direction indicators on, alarm armed/disarmed/trigger.

l

Direction indicators on, alarm trigger only.

l

Direction indicators on, alarm armed/disarmed/trigger.

Dependent on system configuration the direction indicators flash one short pulse to confirm that the alarm is armed 
and flash two short pulses to confirm that the vehicle is super locked.  If the alarm is triggered the direction indicators 
operate in phase with the audible warning.  When the alarm is disarmed, the direction indicators flash one long pulse.

Audible warning
An audible warning device is used to indicate that the alarm has been triggered, or a mislock has occurred, or an EKA  
request has occurred, or the EKA code has been entered.

There are six audible warning configurations:

l

No sound (audible warnings disabled).

l

Alarm sounder only.

l

Vehicle horn only.

l

Alarm sounder and vehicle horn.

l

BBUS only.

l

Alarm sounder, vehicle horn and BBUS.

Depending on which market the vehicle is sold, either the vehicle horn, a specific alarm sounder, or a BBUS operates 
in phase with the direction indicators when the alarm is triggered. The audible warning device operates for 
approximately 30 seconds at 0.25 second on, and 0.25 second off. The BCU allows the alarm to be triggered up to 3 
times in any armed period. 

Theft deterrent LED
An LED located in the instrument pack indicates the status of the alarm system.

There are eight theft deterrent alarm configurations:

l
