Lotus Service Notes
Passive Immobilisation
In order to provide a measure of automatic vehicle security, independent of any driver initiative, the sys-
tem will 'passively' immobilise the engine's cranking and fuel pump circuits after the ignition has been turned
off for 40 seconds, or a similar period has elapsed since the last mobilising command. With the ignition off,
the alarm tell tale will indicate that immobilisation is in effect by briefly flashing every second. With ignition on,
immobilisation is indicated by a continuously lit tell tale.
To mobilise the car (i.e. allow engine starting) with ignition on or off, press once the transmitter centre
button; the alarm tell tale will be extinguished.
Arming the Alarm/Locking the Doors
To lock the doors and arm the alarm, remove the ignition key, close both doors, and check that the engine
lid/tailgate and body front access panels are secure:
- Press once the raised logo button on the transmitter fob.
- This command will be acknowledged by a single flash of the hazard lamps.
- Both doors will be locked, the engine immobilised and the alarm system armed. A settling period of 40
seconds must expire before the ingress sensors become active.
- The alarm tell tale will repeatedly triple flash.
Note:
i) If the system is armed when a door is not fully shut, three triple beeps will sound as a warning and the
doors will not be locked. Opening a door will not trigger the alarm.
ii) If the system is armed when the engine lid/tailgate or a front access panel is not fully closed, three warning
double beeps will be heard, and the doors will not be locked. Opening a door in this instance will trigger
the alarm.
iii) If one transmitter is used to disarm the alarm, and a second transmitter to re-arm, a system test mode will
be initiated, and operational variations will occur. Allow an undisturbed period of 2 minutes to elapse to
restore normal operation.
When fully armed, and after the settling period of 40 seconds has expired, the alarm will be triggered by
any of the following actions:
- Interruption of the car battery power supply or siren cables.
- Energising the ignition circuit ('hot wiring').
- Opening a door;
- Opening the engine lid/tailgate or a front access panel.
- Movement detected within the cabin (unless de-selected).
If the alarm is triggered, the hazard warning lamps will flash and the wailing siren 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 (e.g. door left open), the alarm will repeat for a maximum of eight 30 second cycles
before excluding the triggering sensor for the remainder of the armed period.
To silence the siren, press once the central, disarm button on the transmitter key. If necessary, press a
second time to disarm the alarm.
Alarm Tell Tale Summary
Tell tale off;
Tell tale on;
Brief flash every second; Immobilised with ignition off.
Repeating triple flash;
Interior Movement Sensor
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 shield the signal by placing such items on the bulkhead ledge.
If an animal is to be left in the vehicle, or if for any other reason it is desired to exclude the interior move-
ment sensor when the alarm is set, press once the transmitter logo button in the normal way to set the alarm,
and then press a second time (within 2 seconds) to exclude the interior movement sensor. A single beep will
be heard as confirmation. This exclusion will be automatically cancelled when the alarm is disarmed.
Alarm disarmed, engine mobilised.
Immobilised with ignition on.
Alarm armed.
