triggering signal is still present (e.g. if a door is left open), the alarm will repeat after a short delay, and continue
in this sequence for a total of ten cycles.
To Disarm the Alarm: Press once the embossed red button on the transmitter key. This command will be
acknowledged by:
a single flash of the hazard lamps, accompanied by a short and a long buzz;
the alarm tell tale changing from steady to flashing illumination.
Note that the flashing of the tell tale prior to next switching on the ignition, provides an indication as to
whether or not the alarm had been triggered during the last armed period. If the flashing is regular at one per
second, no triggering had occured, and after 30 seconds the passive immobilisation will take effect and the tell
tale light steady (see above).
If the flashing is irregular:
a single flash followed by a 2 second break indicates that a door, bonnet, or engine lid sensor had been
triggered during the last armed period.
3 flashes followed by a 2 second break indicates that the microwave sensor (interior movement sensor)
had been triggered during the last armed period.
Note that if the alarm is triggered and is disarmed when the siren is sounding, the first press of the red
button will silence the siren but leave the system armed. Press a second time to disarm.
Switching Off Interior Movement Sensing: If an animal is to be left in the vehicle, the alarm can be armed
without the microwave sensor operating; First arm the system in the usual way by pressing once the red
button. Then within 20 seconds, press once the blue button. This latter action will switch off the microwave
sensor, with an indication being provided by the alarm tell tale flashing rather than being on steady. Note that
the sensor will be automatically reinstated next time the alarm is armed.
Alarm Override Switch
A pair of alarm override and immobiliser touch keys are supplied in order to provide for the following
situations:
Vehicle servicing where the battery is to be disconnected;
Long term parking;
Loss of both transmitter keys.
The power sensing circuitry of the alarm will trigger the siren if the power supply is interrupted, regardless
of the arming status. If the main vehicle battery is to be disconnected, and triggering of the alarm is to be
avoided, it is necessary first to turn off the alarm system using the special override key. Fit the special key into
the switch on the siren housing in the top of the passenger footwell, and turn counterclockwise. When work on
the car has been completed, and the battery reconnected, ensure that the alarm is activated by turning the
override key clockwise.
