Lotus Service Notes 340R
When triggered, the electronic siren will sound and the hazard warning lamps will flash 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 alarm when triggered, disarm as described below.
Disarming the Alarm
To disarm the alarm prior to entering the vehicle, or if the alarm has been triggered, press once the button
on the transmitter key. This command will be acknowledged by:
One flash of the hazard warning lamps;
Extinguishing of the alarm tell tale on the fascia top.
If the alarm had been triggered during the last armed period, the alarm tell tale will light and 'off blink' a
code(s) for about 30 seconds to indicate which of the triggers was responsible:
4 blink offs every 6 seconds - engine lid or front access panels;
8 blink offs every 6 seconds - ignition input;
1 blink off every 6 seconds - microwave sensor;
This coding will be repeated each time the alarm is disarmed until the memory is cleared by pressing the
transmitter button with the ignition switched on.
Intrusion Sensing
A microwave sensor is mounted in the
rear bulkhead electronics compartment, and
is able to detect substantial physical move-
ment within the cockpit, and trigger the alarm.
The range and sensitivity of the intrusion sen-
sor may be adjusted if necessary by turning
an adjuster screw on the unit.
If desired, the alarm may be armed with-
out the intrusion sensor or battery interruption
ciruits being active by:
with the alarm disarmed, hold the trans-
mitter button pressed for a 4 second period.
This will be acknowledged by 3 flashes of the
hazard lamps, and blinking of the alarm tell
tale.
Note:
# Intrusion sensing will automatically be reinstated the next time the alarm is armed.
# Do not inhibit operation of the radar detector by placing bags or large objects against the cabin rear
bulkhead.
Transmitter Key Battery Replacement
The batteries for the key head transmitters
should be renewed at six monthly intervals to
ensure continuity of operation.
To replace transmitter battery:
a). Use a thin blade to prise apart the two
halves of the transmitter key head, and with-
draw the battery.
b). The transmitters are powered by a 3v
long life lithium battery type CR2032. With
normal use, this should last between 3 and 5
years. After opening the new battery packag-
ing, touch only the sides of the battery, and fit
the battery into the key case with the positive
side (+) upwards as shown.
c). Press the battery case together.
