Visual and Audible Warnings
Audible and visual warnings are dependant on market legislation. The hazard warning lamps are controlled by two
outputs from the anti-theft alarm ECU; one for the LH lamps and one for the RH lamps. To illuminate the warning
lamps the output from the ECU is at battery voltage. When the lamps are off, the output is driven to earth.
When the alarm is armed the hazard warning lamps will flash three times to indicate that the system is active.
When the alarm is triggered the sounder will operate in either a pulsed or continuous tone (dependant on market
legislation) and the hazard warning lamps will flash at 0.5 second on/off intervals for 30 seconds. The alarm
system can be triggered for up to three times in any one alarm armed cycle. When the alarm system is disarmed
confirmation will be by one single flash of the hazard warning lamps for 0.3 seconds.
If the hazard warning lamps are active when an alarm trigger is active or the alarm is armed, the visual alarm
active visual warning using the hazard warning lamps will be cancelled.
In addition to the visual and audible warnings, the security LED in the instrument pack also displays alarm system
status information.
