Lotus Service Notes
- Two flashes of the hazard warning lamps;
- Continuous flashing of the security tell tale.
Check that these indications occur. If not, press the button a second time, as the first press may have
only switched off the passive immobilisation (see above).
Note that if the system is armed when a door or engine cover/front access panel is not fully closed, a
continuous buzz will be heard as warning. If still open after expiry of the arming period, (see below) the alarm
will be armed with that switch group (both doors, or front/rear access lids) excluded from the circuit.
After arming the system, the engine is immediately immobilised, but a period of approximately 45 seconds
must elapse before all functions and sensors become fully active. After this time, the alarm will be triggered
by any of the following actions:
- Interruption of the vehicle battery power supply.
- Energising the ignition circuit ('hot wiring').
- Opening a door;
- Opening the engine cover or a front access panel.
- Movement detected within the cabin.
When triggered, the hazard warning lamps will flash and the electronic wailing siren will sound for a
period of approximately 30 seconds before closing down and resetting, ready for any further triggering input.
If a trigger is continuously present, the alarm will repeat after a short delay, and continue in this sequence for
about ten cycles.
To silence the siren when triggered, press once, and for a full second, the larger button on the transmitter
fob. This will not affect the status of the alarm which will remain armed.
Disarming the Alarm
To disarm the alarm, press once, and for a full second, the larger button on the transmitter fob. This com-
mand will be acknowledged by:
- One flash of the hazard warning lamps;
- Extinguishing of the security tell tale.
If the alarm had been triggered during the last armed period, the disarm command will be acknowledged
by the hazard lamps flashing 4 times, and the buzzer sounding 4 times. The security tell tale will then flash a
code to indicate the triggering source:
- One pulse flashing: door, engine cover/boot lid or body front access panel. On USA cars, check that the
interior lamp is not switched off.
- Two pulse flashing: movement detected in cabin by microwave sensor.
- Four pulse flashing: tampering with ignition circuit.
- Six pulse flashing: interruption of battery supply.
- Seven/Eight pulse flashing: serial data fault; alarm harness including microwave sensor cables and im-
mobiliser fuse.
The coding will be deleted when the ignition is next turned on.
Emergency Disarming/Mobilising
If the transmitter fobs are lost or damaged, the alarm system owner's unique PIN may be used to disarm
the alarm and/or mobilise the engine provided that access is available to the cabin. Follow the transmitter fob
programming instructions (see later) from step 3.
Intrusion Sensing
A microwave sensor is mounted behind the cabin rear bulkhead trim panel, and is able to detect substantial
physical movement within the cockpit, and trigger the alarm. Microwave transmissions are blocked by metal
objects, so it is important not to corrupt the signal by placing such items on the bulkhead ledge.
If desired, the alarm may be armed without the intrusion sensor or battery interruption circuits being active
by arming the system in the usual way with the transmitter larger button, and within 20 seconds, pressing the
smaller button twice.
