1. Introduction
About the Security System
The Sigma S-Series security systems build on the features of previous Sigma
models and offer the highest level of security, convenience and flexibility.
Operated correctly, this Sigma security system will protect your vehicle
against today’s sophisticated thief, however this security system is designed
as a deterrent against the theft of, or from a vehicle, and as such cannot offer
any guarantee against such occurrences. Always follow the advice of the
Police, always lock your vehicle, park in a well-lit area whenever possible and
never leave valuable items in a vehicle where they can be seen. Due to the
advances in vehicle security, more vehicles are being stolen using the
owner’s keys or in car-jacking situations. S30 and S34 models have an
optional Internal Panic Button facility, sophisticated locking options and
offer a Key Theft Protection feature (optional keypad required for S34) to
prevent carjacking and the theft of a vehicle even with the keys, however,
always ensure your keys are not left unattended or in a vulnerable place.
Your local Police Crime Prevention Officer will be pleased to advise you
about general vehicle security precautions.
The Sigma S30 & S34 vehicle security systems comply with the Thatcham
MIRRC criteria. The Thatcham MIRRC organisation was set up on behalf of
the ABI (Association of British Insurers) to establish design and
manufacturing quality standards for vehicle security systems. Security
systems complying with the Thatcham MIRRC criteria are rigorously tested
for quality, functionality, electro-magnetic interference resilience and their
ability to resist physical and electronic attack from a vehicle thief.

Parts included in your Sigma Vehicle Security System
• Certificate of Installation. When completed correctly by your installing dealer
this certificate may entitle you to a discount on your vehicle insurance premium
(applies to most major insurance companies).
• Electronic Control Unit. The security system’s ECU is concealed within the
vehicle and connected to the various points, forming the “brain” of the whole
system. The immobilisation relays and wiring plugs are covered by a steel
housing to protect them from physical attack on the S30 models with Thatcham
approved immobilisation.
• Immobilisation. 2 self-arming, independent, engine immobilisation circuits are
provided on the S30 Thatcham approved security system. A single
immobilisation circuit is also available on the S34 security system, which only
becomes self-arming if the Key Theft Protection feature is turned on.
• Perimeter Protection. Provided by independent boot/bonnet and door circuits.
The door circuits also being configurable for positive or negative inputs.
• Radio Keys. Two, single button, weatherproof, high security Radio Keys which
are resistant to radio frequency code scanning/grabbing and incorporate a 66-
bit random code encryption.
• Siren. The compact high power Siren unit has an independent self-contained
power supply and is connected to the Security System’s control unit by a secure
data-link.
• Tri-colour LED. The dashboard mounted LED (light emitting diode) is the
security system’s status light and also acts as a visual deterrent.
• Ultrasonic Sensors. Intelligent, self-adjusting, ultrasonic sensors provide
interior protection and are mounted inside the passenger compartment.
• Unique PIN Code. Two self-adhesive labels show the unique PIN code and serial
number for your security system. These should be kept in a safe place.
Optional Items
• Accessories. Pagers, Internal Sirens, LEDs and Window Closers etc. can be
activated from the unit’s accessory outputs (max. current 200mA).
• Additional Sensors. Glass Break, Tilt, Dual/Single Stage Shock and Dual/Single
Zone Microwave Sensors can be plugged directly into the sockets on the rear of
the unit to work alongside the security system’s Ultrasonic Sensors that provide
interior protection. A pre-warn facility is built into the security system for Dual
Stage Sensors.
• Internal Panic Switch. A dash mounted switch that will instantly trigger the
siren and flash the indicators in the event of personal attack.
• Multifunction Keypad. The dashboard mounted Keypad can be used as an
emergency override to arm/disarm the security system (refer to page 21), to
change the way the system operates (page 25) and is required to operate the
system’s Key Theft Protection feature (pages 11 & 14).
• Touch Key Override. A dashboard mounted Receptacle and two Touch Keys
provide a heavy-duty emergency override to arm/disarm the security system.
• Two Button Radio Key. Allows additional control of the alarm system’s outputs
when the Extended Lock Pulse, Total Closure, and Total Open/Boot Release
features are required to be operated from the Radio Key in addition to Panic
Mode. Also required to Remotely Delete Ultrasonic Sensors off.

Programmable Features*
The security system is microprocessor controlled and this enables you to benefit
from a number of enhanced user-friendly convenience and security features. If you
wish to have any of these enabled, consult your dealer. These include:
• Auto-Arm can automatically arm the security system a timed period after
the last door is closed, if the system is accidently left disarmed. This feature
can also include locking if required.
• Auto-Rearm can automatically re-arm the security system (and re-lock the
doors) if a door is not opened in a timed period following the system having
been disarmed.
• Closed Loop Protection Built in accessory protection circuit.
• Door Open, Closed Loop & Auto-Arm Warning Bleeps will alert you, with a
series of bleeps when first armed, that a door, boot or the bonnet is open,
the Closed Loop Protection circuit is broken or Auto-Arm is selected.
• Extend CDL Lock Output this feature enables the CDL Lock Pulse to be
extended when the Radio Key button remains held on arming (up to a
maximum of 26 seconds). This feature provides an alternative method to
operating Total Closure on vehicles equipped with a Total Closure circuit
that can be operated in this way.
• Headlamp Illumination provides an output to illuminate the vehicle’s
headlamps on arming (and disarming if required) to illuminate your way
from the vehicle.
• Interior Lamp Illumination provides an output to illuminate the vehicle’s
interior lamp on disarming the system.
• Key Theft Protection with this feature selected, even if the vehicle’s keys
and Radio Key are used to disarm the alarm system the vehicle can only be
started after entering the correct 4-digit PIN into the Keypad.
• Safety Lock/Unlock can automatically lock the doors and boot when the
ignition is turned on, unlocking them again when the ignition is turned off.
• Total Closure this feature can provide an output when arming the system.
The output can be operated in one of 2 ways; “Timed” in which case the
output always occurs upon arming for a preset period, or “Hold Down”
where the output only occurs when, and for the period that, the Radio Key
button remains depressed (up to a maximum of 26 seconds).
• Total Open/Boot Release this feature can provide an output when
disarming the system. The output can be operated in one of 2 ways; “Timed”
in which case the output always occurs upon disarming for a preset period,
or “Hold Down” where the output only occurs when, and for the period that,
the Radio Key button remains depressed (up to a maximum of 26 seconds).
• 2nd Stage Unlock This feature allows the user to only unlock all the vehicle’s
doors and boot when specifically required. Normal disarming of the system
provides a Standard CDL Unlock output that can be configured to unlock
the driver’s door only, however, pressing the Radio Key button again briefly
provides a 2nd Stage. Unlock output to unlock the remaining doors and the
boot.
* Some of the above features may not be available on certain vehicles or may
require additional labour and/or parts, incurring extra cost. Please consult your
installing dealer.

2. Basic Operation of the Security System
Arming the Security System
• Vacate the vehicle closing all windows, doors, boot and bonnet.
• Briefly press and release the Radio Key button, whilst standing near the vehicle.
• The security system will acknowledge arming by illuminating the vehicle’s
hazard warning lights for a 3 second period (if the hazard lights flash 2, 3, 4, 5 or
6 times at this point this indicates that certain sensors have been deleted - see
page 9).
• The doors will lock if this facility is included with your security system.
The security system will then enter a “pre-set state”, which comprises of the Settle Time
and Ultrasonic Threshold Time. This period is used by the security system’s
microprocessor to monitor the vehicle’s internal environment and adjust the sensitivity
of the ultrasonic sensors if necessary.
If a door, boot or bonnet has been inadvertently left open or the optional Closed Loop
Protection Circuit is broken the siren will continuously bleep, (if the Door Open, Closed
Loop & Auto-Arm Warning Bleep feature is selected), for 15 seconds as a warning to
close everything securely. If this happens, disarm the security system (see below), close
all doors etc. securely, and re-arm. Failure to do this within 15 seconds will result in a full
alarm trigger.
Disarming the Security System
• Briefly press and release the Radio Key button, whilst standing near the vehicle.
• The security system will acknowledge disarming by illuminating the vehicle’s
hazard warning lights for a 1 second period.
• If the alarm has been triggered during the armed period, then the siren will emit
3 Trigger Warning Bleeps.
• The doors will unlock if this facility is included with your security system.
Ultrasonic Interior Protection
The S-Series range of alarm systems are all supplied with sophisticated microprocessor
controlled Ultrasonic Sensors as the primary interior protection system. Unlike
conventional ultrasonic detectors this system ensures that an actual entry has
occurred rather than just air movement, air pressure fluctuation, seat belt movement,
etc.
Whenever the system is armed:
• Initially the dashboard LED displays a rapid green flash for the first 15 seconds.
This is the Settle Time, during which the Ultrasonic Sensors are inactive. This
allows the air movement inside the vehicle to stabilise.
• The dashboard LED then displays a long bright amber flash for the next 15
seconds. During this Ultrasonic Threshold Time, the Ultrasonic Sensors are now
active. The alarm system’s microprocessor monitors the interior of the vehicle,
and if any “background” movement is detected that would otherwise cause a
false alarm, the sensitivity is reduced from that programmed by the installer.
The amber LED will illuminate for a second, to indicate the detection of any
“background” movement.

9
• After the first 32 seconds a short bright red flash from the dashboard LED every
second indicates that the system is now fully armed and the Ultrasonic Sensors
are set to their pre-programmed maximum or their automatically reduced level
if some “background” movement was detected during the Threshold Time.
The detection system also employs a movement/time method where a certain amount
of movement in a given time is also required to cause a trigger.
This method of detection offers a high level of protection against false alarms
commonly associated with other systems employing inferior methods of detection.
Arming the Security System with Ultrasonic Sensors Deleted
It may sometimes be necessary to arm the security system with certain sensors deleted
- such as the Ultrasonics Sensors if you wish to leave people or animals inside the
secured vehicle, although sensible safety precautions should be exercised if
considering this action!
The Ultrasonic Sensors, and any other optional sensors that may have been added to
the Dual or Single Stage Accessory Sensor Sockets, can be deleted in a number of
combinations. This can be done in three ways:
1. Using the optional Keypad, before exiting the vehicle:
See Page 25 for details.
2. Using the optional Two Button Radio Key, from outside the vehicle after
arming the system:
See the Two Button Radio Key operating instructions for details.
3. Using the Radio Key and ignition, before exiting the vehicle:
• With the vehicle’s ignition turned on, briefly press and release the Radio
Key button the necessary number of times to select the sensor
combination required, shown in the table on the following page.
• The dashboard mounted LED will flash each time the Radio Key button
is pressed.
• Turn off the vehicle’s ignition.
• Vacate the vehicle closing all doors, boot and bonnet.
• Briefly press and release the Radio Key button, whilst standing near the
vehicle.
• The security system will acknowledge arming with the necessary sensor
combination by flashing the vehicle’s hazard warning lights the
corresponding number of times, instead of the normal 3 second
illumination.
• The doors will lock if this facility is included with your security system.
In all cases the deleted sensors will be restored the next time you arm the security
system in the normal way.

10
Panic Mode/Siren Test
To enter Panic Mode press and hold the Radio Key button down for 3 seconds, the
system will change state (i.e. from armed to disarmed or disarmed to armed) and then
enter Panic Mode. Whilst in Panic Mode the siren will sound and the hazard lights will
flash indefinitely. To exit Panic Mode, briefly press and release the Radio Key button.
This time the system will not change state, just exit Panic Mode.
N.B. If any of the Extended CDL Lock Pulse, Total Close or Total Open/Boot Release
features have been programmed to occur when the Radio Key button is “Held Down”,
then Panic Mode will no longer be available from the Single Button Radio Key. The
optional Two Button Radio Key should be used if Panic Mode is still required from the
Radio Key in addition to “Hold Down” operation of these features from button 1.
Starting the Vehicle – S30 Models without Key Theft Protection
The security system is armed and disarmed with the Radio Keys, however the two
immobilisation circuits on the S30 also automatically set a pre-set time (the Stall & Start
Time; usually 30 seconds) after the ignition is switched off. This is a Thatcham MIRRC
requirement, so that the driver cannot forget to set the immobilisation system.
Disarming the system and starting the vehicle:
Whilst the security system is fully armed the dashboard mounted LED will display a
short bright flash every second.
• Press the Radio Key button briefly to disarm the security system in the normal
way.
• The dashboard mounted LED will be switched to a solid green state for a pre-
set time (the Stall & Start Time; usually 30 seconds). Whilst the LED is solid green
you may start the vehicle.
If the ignition is not turned on whilst the green LED is illuminated (i.e. within 30 seconds
of disarming the system, or turning the engine off), the immobiliser will re-set. When
the immobiliser automatically re-sets, this is indicated by a short bright red flash from
the dashboard LED every 3 seconds.
Starting an immobilised vehicle:
• To start the vehicle simply turn on the ignition, briefly press and release the
Radio Key button (the dashboard mounted LED will flash once).
• Start the vehicle.
You may repeat this “switch ignition on – press Radio Key button – start vehicle”
sequence as often as you like.
Alternatively, when the dashboard LED is displaying a short bright red flash every 3
seconds, arm then immediately disarm the security system, then start the vehicle
within 30 seconds (dependent on programming) whilst the LED is solid green again.

Starting the Vehicle – S30 & S34 Models with Key Theft Protection
With the Key Theft Protection feature selected, only the alarm system is armed and
disarmed by the Radio Keys (or Touch Keys, Keypad or Ignition PIN entries). The
immobilisation circuit(s) act independently of the alarm, setting automatically a pre-
set time (the Stall & Start Time; usually 30 seconds) after the ignition is switched off and
can only be unset after disarming the alarm, by entering the security system’s unique
PIN into the Keypad (or Ignition in extreme cases). This feature prevents theft of a
vehicle even with the owner’s keys. The Keypad only allows three attempts to enter the
correct PIN code. If a third incorrect PIN code is entered, the security system will ignore
all further PIN code entries for 3 minutes. This is a security feature.
Disarming the system and starting the vehicle:
Whilst the security system is fully armed the dashboard mounted LED will display a
short bright red flash every second.
• Disarm the alarm system in the normal way (or Touch Key, Keypad or Ignition
PIN).
• The dashboard mounted LED will be switched to a solid red state for a pre-set
time (the Stall & Start Time; usually 30 seconds) after disarming, as a warning
that Key Theft Protection is active and the vehicle is still immobilised. When this
period lapses the LED returns to the usual immobilisation indication of a short
bright red flash every 3 seconds. (Turning the ignition on will cause the LED to
extinguish, but the vehicle will remain immobilised).
• To start the vehicle (whilst the LED is now flashing, in the previous solid state or
even with the ignition on) simply enter the security system’s unique PIN into
the Keypad.
• If the correct PIN is entered the LED will extinguish, indicating that the vehicle
can now be started (If the ignition is on when the correct PIN is entered, then
the LED will already be off, so there will be no confirmation).
If the ignition is not tuned on within 30 seconds of entering the correct PIN, or turning
the engine off, the immobiliser re-sets, this is indicated by a short bright red flash from
the dashboard LED every 3 seconds.
Starting an immobilised vehicle:
• To start the vehicle (whilst the LED is flashing or even with the ignition on)
simply enter the security system’s unique PIN into the Keypad.
• If the correct PIN is entered the LED will extinguish, indicating that the vehicle
can now be started (If the ignition is on when the correct PIN is entered, then
the LED will already be off, so there will be no confirmation).
IMPORTANT NOTICE
Immobilisation only is indicated by a short bright red flash from the dashboard
LED every 3 seconds. Although the vehicle is immobilised, the alarm system is not
armed in this instance and the interior, doors, boot and bonnet circuits are
not protected until the security system is armed. Only when the dashboard
mounted LED displays a short bright red flash every second is the security
system fully armed.

12
If the Security System is Triggered
If the security system is triggered, the hazard lights will flash and the siren will sound
at full power for approximately 30 seconds, after which the hazard lights and siren
will stop and the security system will immediately re-arm ready for any further attack.
The security system has an anti-nuisance feature, known as the Shut Down Count
which allows each protected circuit to only trigger 10 times (the Shut Down Count) in
any armed period, after which the circuit causing the continual trigger will shut
down, leaving all other circuits protected.
Disarming the security system whilst the siren is still sounding:
Briefly press the Radio Key button to disarm the security system whenever it is
sounding. If the door locking option is installed however, and the Radio Key button is
pressed to disarm a sounding system, the doors will remain locked as a safety feature.
To unlock the doors simply re-arm then disarm the security system again.
Disarming the security system after a trigger has occurred:
Briefly press the Radio Key button to disarm the security system in the normal
manner. The doors will unlock if this facility is included with your security system. The
security system will acknowledge disarming by illuminating the vehicle’s hazard
warning lights for a 1 second period and 3 Trigger Warning Bleeps will be heard to
indicate that a trigger has occurred during the last armed period.
Trigger Identification:
Should the alarm have been triggered in the last armed period, then the dashboard
LED will flash to confirm the circuit triggered, when the ignition is turned on. The
number of flashes corresponds with the circuits in the table below. The ignition can
be turned off and back on to display the circuit as many times as necessary, however
arming the security system again will re-set the memory.

3. Operation of Programmable Features
(if selected and/or installed by your dealer)
Auto-Arm
Auto-Arm automatically arms the security system if the vehicle is accidentally left
unarmed. The security system will automatically arm a pre-set time (the Auto-Arm
Time; usually 60 seconds) after the ignition has been switched off, the vehicle
vacated, and the last door, boot or bonnet has been closed. If a door, boot or bonnet
remains open, or is opened during the Auto-Arm Time, the security system will not
arm until that door, boot or bonnet is closed. As a warning that Auto-Arm is going to
automatically arm the system, the siren will sound 2 warning bleeps when you open
the door to exit the vehicle.
Note: If the “Door Open, Closed Loop and Auto Arm Warning Bleeps” have been
programmed to “off” there will be no warning bleeps to advise you that this feature is
active.
Auto-Arm with Door Locking
This option operates in the same way as Auto-Arm; however the vehicle’s doors will
also automatically lock at the same time the security system Auto-Arms, if this facility
is included with your security system.
Note: Be sure to remove your car keys when leaving the vehicle if you have chosen
the Auto-Arm with Door Locking option, otherwise they may be locked in the vehicle!
Auto-Rearm
Auto-Rearm automatically re-arms the security system if it is accidentally disarmed.
The security system will automatically re-arm and lock (if this facility has been
included with your security system) a pre-set time (the Auto-Rearm Time; usually 60
seconds), from the system being disarmed by the Radio Key, provided that no door,
bonnet or boot has been opened during the Auto-Rearm Time. Any sensors deleted
for the previous armed period will remain deleted if the system Auto-Rearms. This
feature prevents the vehicle being vulnerable if the Radio Key button is pressed by
mistake – perhaps from inside your house while your car is parked close by in the
driveway or street, or if children press the Radio Key button in play! This feature
provides extra security with no inconvenience.
Door Open, Closed Loop & Auto-Arm Warning Bleeps
The security system emits “warning bleeps” which can be turned off by your dealer if
required. The “warning bleeps” take the form of 2 bleeps whenever a door, boot or
bonnet is opened only if Auto-Arm is selected and as a series of repeated bleeps for 15
seconds after the security system is armed as a warning that either:
a) A door, boot or bonnet is still open or ajar.
b) The optional Closed Loop Protection circuit is broken.
When the security system is armed and the repeated bleep is heard, if the security
system is not disarmed, the open door, bonnet or boot not closed or the Closed Loop
Protection circuit not completed within 15 seconds, the security system will trigger.

14
The trigger will continue for ten 30 second cycles, after this the circuit causing the
trigger will be ignored by the security system (to conform with noise abatement laws)
and is no longer protected.
Note: One door left open in this way may affect the protection on all other doors,
depending on the make and model of vehicle. With the “Door Open Warning
Bleeps” programmed to “off” this facility will function in the same way but without
the audible warning.
Extend CDL Lock Output*
This feature is not available on all makes and models of vehicles, but provides an
alternative to the Total Closure output. It is only suitable for vehicles that close the
windows/sunroof when the vehicle’s key is held in the lock position. If this feature has
been selected on your security system and window/sunroof closure is required then
instead of giving the Radio Key button a brief press to arm the security system, press
and hold down the button until the windows/sunroof are fully closed (maximum 26
seconds). Releasing the Radio Key button at any time during window/sunroof closure
stops the windows/sunroof from moving any further. Users of this facility should be
particularly cautious when children or animals are inside or near the vehicle.
Note: If you choose this facility then the Personal Panic/Siren Test feature will no
longer be available from the Single Button Radio Key.
Headlamp Illumination*
Whenever the security system is armed the vehicle’s headlamps will illuminate for a
preset time (the Headlamp Illumination Time; usually 30 seconds), to illuminate your
way from the vehicle. If required, the headlamps can also illuminate for the same
period when disarming; in this instance switching the vehicle’s ignition on will also
extinguish the headlamps.
Interior Lamp Illumination*
Whenever the security system is disarmed the vehicle’s interior lamp will illuminate
for a pre-set time (the Auto-Rearm Time; usually 60 seconds), or until the vehicle’s
ignition is switched on.
Key Theft Protection*
With this feature selected, disarming the security system with the Radio Key (or
Touch Key, Keypad or Ignition PIN) no-longer automatically deactivates the
immobiliser. Before the vehicle can be started the security systems unique PIN must
be entered into the Keypad once the alarm is disarmed. This prevents theft of a
vehicle even with the owner’s keys.
If this feature is selected on S34 models, the single immobilisation circuit becomes
self-arming a pre-set time (the Stall & Start Time; usually 30 seconds) after the
ignition is turned off. This provides additional security, so that if a vehicle were to be
stolen in a carjacking situation (whilst the engine was still running), then 30 seconds
(dependent on programming) after the ignition is next turned off, the vehicle will not
re-start without entering the security systems unique PIN. Refer to Starting the
Vehicle - S30 & S34 Models with Key Theft Protection on page 11 for details of
operation.

15
Safety Lock/Unlock*
Many Police forces now recommend that you lock your vehicle’s doors whilst driving,
Safety Lock/Unlock prevents you from having to remember to do so and is available if
the door locking facility is included with your system. If all the doors, bonnet and boot
are closed and you turn on the vehicle’s ignition all the doors and boot will lock.
When you turn off the ignition all the doors and boot will then unlock. To stop the
doors and boot locking on a single occasion (for example if you wish to start the
engine and then vacate the vehicle to scrape ice from the windows), open a door and
turn on the vehicle’s ignition, after 1 second the vehicle’s hazard lights will give a
single flash. It is then safe to close your door and Safety Lock/Unlock will not lock your
doors until the next time you turn the vehicle’s ignition off then on again.
This feature can also be turned on using the Keypad in the following way:
• To enable Safety Lock/Unlock turn on the vehicle’s ignition, type 7 on the
Keypad and immediately turn off the ignition. Safety Lock/Unlock will now
function as described.
• To disable Safety Lock/Unlock turn on the vehicle’s ignition, type 7 on the
Keypad and immediately turn off the ignition. Safety Lock/Unlock is now
disabled and will not operate your door locks.
Note: For occupant safety the Safety Lock/Unlock feature is configured to only
activate Single Locking circuits & should never operate a vehicle’s Double or Dead
Locking.
Total Closure*
The Total Closure output can be programmed to operate in one of two ways:
1. “Timed”:
This method of operation should only be used on vehicles equipped with built-in
“Anti-Trap” features. If Total Closure has been programmed to operate for a “Timed”
period, then closure of the vehicle’s windows/sunroof will always occur on arming for
the timed period. This timed period is adjustable up to a maximum of 99 seconds.
Users of this facility should be particularly cautious when children or animals are
inside or near the vehicle.
Note:The Panic Mode/Siren Test feature is still available from the Single Button
Radio Key when “Timed” operation is selected.
2. “Hold Down”:
If Total Closure has been programmed to operate on “Hold Down”, then closure of the
vehicle’s windows/sunroof can be performed only when required. In such instances,
instead of giving the Radio Key button a brief press to arm the security system, press
and hold down the button until the windows/sunroof are fully closed (maximum 26
seconds). Releasing the Radio Key button at any time during window/sunroof closure
stops the windows/sunroof from moving any further. Users of this facility should be
particularly cautious when children or animals are inside or near the vehicle.
Note: If you choose this “Hold Down” operation then the Panic Mode/Siren Test
feature will no longer be available from the Single Button Radio Key.

16
Total Open/Boot Release*
The Total Open/Boot Release output can be programmed to operate in one of two
ways:
1. “Timed”:
The “Timed” method of operation is not ideal for most applications as it always
attempts to open the vehicle’s windows/sunroof or boot every time the system is
disarmed. If Total Open/Boot Release has been programmed to operate for a “Timed”
period, then opening of the vehicle’s windows/sunroof or boot will always occur on
disarming for the timed period. This timed period is adjustable up to a maximum of
99 seconds.
Note: The Panic Mode/Siren Test feature is still available from the Single Button
Radio Key when “Timed” operation is selected.
2. “Hold Down”:
If Total Open/Boot Release has been programmed to operate on “Hold Down”, then
opening of the vehicle’s windows/sunroof or boot can be performed only when
required. In such instances, instead of giving the Radio Key button a brief press to
disarm the security system, press and hold down the button until the
windows/sunroof are fully open or the boot opens (maximum 26 seconds). Releasing
the Radio Key button at any time during window/sunroof open stops the
windows/sunroof from moving any further.
Note: If you choose this “Hold Down” operation then the Panic Mode/Siren Test
feature will no longer be available from the Single Button Radio Key.
2nd Stage Unlock*
The Total Open/Boot Release output can be programmed to operate in one of two
ways:
1. “Timed”:
The “Timed” method of operation is not ideal for most applications as it always
attempts to open the vehicle’s windows/sunroof or boot every time the system is
disarmed. If Total Open/Boot Release has been programmed to operate for a “Timed”
period, then opening of the vehicle’s windows/sunroof or boot will always occur on
disarming for the timed period. This timed period is adjustable up to a maximum of
99 seconds.
Note: The Panic Mode/Siren Test feature is still available from the Single Button
Radio Key when “Timed” operation is selected.
2. “Hold Down”:
This feature compliments Safety Lock, and provides additional security when
entering the vehicle, especially if the driver is usually the only occupant. With the 2nd
Stage Unlock feature selected upon disarming the system in the normal way this will
only unlock the driver’s door. To unlock the remaining doors and the boot, the Radio
Key button should be pressed briefly again immediately after disarming the system
and the driver’s door unlocking.
Note: If the Total Open/Boot Release feature is programmed for both “Hold Down”,
2 Stage Unlock and both outputs are required on disarming, then the Radio Key
button should be “Held Down” on the 2nd press.
* These features may not be available on certain vehicles or may require additional
labour and/or parts, incurring extra cost. Please consult your installing dealer.

4. Radio Keys
Your Sigma security system’s Radio Keys (Part number SIGAC111) are small radio
transmitters operating on the approved frequency of 433.92 MHz. Although
extremely robust you must take care of these remote keys to prolong their working
life.
• If you lose or damage a Radio Key, replace it immediately.
• If you need more than two Radio Keys for your security system, your installing
dealer can supply a third or fourth key (a maximum 4 to preserve security).
• The Radio Keys are battery powered and although the batteries are long life
lithium cells, it is recommended that these are changed regularly. Your
installing dealer will be pleased to supply these for you.
Replacing the Battery in a Radio Key
Eventually the lithium battery cell (model number CR2016) will need replacing.
Battery life will depend on use, however, to maintain optimum performance of the
Radio Key it is good practice to replace the lithium battery cell regularly.
There is one cell in each Radio Key. A symptom of low battery power is reduced
operating range from the vehicle. Replacement battery cells should be available from
your installing dealer.
Locate the recess near the keyring and using a small
coin or flat blade; gently prise apart the two halves of
the Radio Key casing.
Note the orientation of the old battery and slide it out
from beneath the spring contact, taking care not to
damage it. Carefully slide the new battery beneath
the spring contact ensuring that the + sign, which is
stamped on one face of the battery, is facing upward
as shown in the photograph. Place the circuit board
within the rubber insert and then clip both halves of
the Radio Key casing back together.
CAUTION:
Lithium battery cells should not be exposed to temperatures exceeding 60°C
(140°F) & may explode or leak if recharged, incinerated or short-circuited. You
must dispose of depleted lithium batteries carefully. Your local authority will
advise you of the correct disposal method in your area.
Teaching New Radio Keys to the Security
System
Radio Keys can be programmed into the
security system using the Ignition PIN
Procedure or optional Keypad. Refer to pages
19-23 of this manual for details.

5. Using the Ignition PIN Procedure
IMPORTANT NOTICE:
In the following sections describing the operation of the Ignition PIN Procedure,
reference to a PIN code will be made. The PIN code for your security system will
have been issued to you on two self-adhesive labels which must be kept in a safe
place. This PIN code is unique to your security system and acts as an emergency
override when entered during the Ignition PIN Procedure and/or into the optional
keypad. You can change the PIN code printed on the issued labels, to one of your
own choice that you can easily remember, however, failure to recall your PIN code
could increase the cost of replacing or adding further Radio Keys and will prevent
you and your installing dealer from overriding the security system in the unlikely
event of Radio Key failure. If you do not know, or have forgotten your PIN code then
your installing dealer can reset this for you, provided that the security system is not
armed. The system’s PIN can only be changed using the keypad.
Disarming the Security System
If the Radio Key fails to operate the security system, due to a depleted battery in the
Radio Key for example or its total loss/damage, the security system can be disarmed
using the Ignition PIN Procedure (alternatively the optional Keypad and Touch Key
can also be used as an override, if supplied with your system. See pages 21 & 20
respectively).
To disarm the security system using the Ignition PIN Procedure:
• Unlock the driver’s door with the vehicle’s key and enter the vehicle (the siren
will sound).
• Cycle the ignition 3 times in 7 seconds i.e. off to on, off to on, off to on (the siren
will sound, if not already doing so).
• The LED will now display solid green for 3 seconds, before proceeding to flash
red. If the first digit of the security system’s PIN is 0, then the ignition must to
turned off whist the LED is still green. Otherwise, allow the green LED to
extinguish and then count the red flashes and turn the ignition off
immediately after the corresponding flash i.e. If the first digit is 3, turn the
ignition off after the 3rd red flash.
• With the first digit selected turn the ignition back on. The LED will display solid
green again for 3 seconds, before proceeding to flash red. Select the 2nd, 3rd
and 4th digits in the same manner as the first.
• When the ignition is turned off to select the 4th digit, the security system will
either:
a) Disarm in the normal way if the PIN code is correct.
If the security system incorporates a self-setting immobiliser (S30 models only) start
the vehicle within 30 seconds. If the Key Theft Protection feature is selected, the
PIN must be entered again, in the same way, now to unset the immobiliser.
b) Remain armed if the PIN code is incorrect.
The security system only allows 3 attempts to enter the correct PIN code.
Note: IF a 3rd incorrect PIN code is entered, the security system will ignore all
further PIN code entries, whether by Ignition Procedure or Keypad, for 3 minutes.
This “PIN lockout” is a security feature.

Teaching New Radio Keys & Touch Keys to the Security System
IMPORTANT NOTICE:
When teaching one or more Radio Keys into the security system all previous
Radio Keys will be erased from the system, similarly teaching one or more Touch
Keys into the system will erase all previous Touch Keys. Therefore, you must
always teach ALL the Radio Keys required to operate the security system at the
same time or, if programming Touch Keys, ALL the touch keys at the same time.
Programming only Radio Keys however, does not delete the current Touch Keys
and vice versa.
If an additional Radio Key or Touch Key is required or an existing Radio Key or Touch
Key is lost the new key can be programmed to the security system using the Ignition
PIN Procedure (alternatively the optional Keypad can also be used to teach Radio
Keys & Touch Keys, if supplied with your system. See page 23 & 24).
To programme new Radio Keys and/or Touch Keys:
• Ensure all the Radio Keys and/or Touch Keys required to work the system are
at hand and that the security system is disarmed (using an existing Radio Key,
Touch Key, Keypad or previously described Ignition PIN Procedure).
• Cycle the ignition 3 times in 7 seconds i.e. off to on, off to on, off to on. The LED
will now display solid green for 3 seconds, before proceeding to flash red. If the
first digit of the security system’s PIN is 0, then the ignition must be turned off
whilst the LED is still green. Otherwise, allow the green LED to extinguish and
then count the red flashes and turn the ignition off immediately after the
corresponding flash i.e. If the first digit is 3, turn the ignition off after the 3rd
red flash.
• With the first digit selected turn the ignition back on. The LED will display solid
green again for 3 seconds, before proceeding to flash red. Select the 2nd, 3rd
and 4th digits in the same manner as the first.
• When the ignition is turned off to select the 4th digit, the LED will display 2 red
flashes every 2 seconds to indicate the security system is ready to learn Radio
Keys and/or Touch Keys in the next 15 seconds.
• If Radio Keys are to be taught press the 1st Radio Key button briefly. The
dashboard LED will illuminate red for 1 second and the siren will bleep as
confirmation that the Radio Key has been learnt. Repeat this for the remaining
Radio Keys.
• If Touch Keys are to be taught briefly press the 1st Touch Key to the receptacle
and remove it. The dashboard LED will illuminate red for 1 second and the
siren will bleep as confirmation that the Touch Key has been learnt. Repeat
this for the remaining Touch Keys.
15 seconds after the last Radio Key or Touch Key has been taught the security
system will automatically exit programming mode.

6. Using the Optional Touch Key Override
Your Sigma security system’s Touch Keys utilise Dallas IC technology. Although
extremely robust you must take care of these Touch Keys to prolong their working
life.
• If you lose or damage a Touch Key, replace it immediately.
• Your installing dealer can supply up to 4 Touch Keys to operate your security
system (maximum 4 to preserve security).
• The Touch Keys are not battery powered and so should not be split or require
any maintenance.
Disarming the Security System
If the Radio Key fails to operate the security system, due to a depleted battery in the
Radio Key for example or its total loss/damage, the security system can be disarmed
using the Touch Key (alternatively the built-in Ignition PIN Procedure or the optional
Keypad, if supplied with your system, can also be used. See pages 18 & 21). To do this,
enter the vehicle (the siren will sound), briefly press the Touch Key to the receptacle
and remove it, the security system will disarm in the normal way. If the security
system incorporates a self-setting immobiliser (S30 models only) start the vehicle
within 30 seconds. If the Key Theft Protection feature is selected, the PIN must now
be entered using the Keypad (or Ignition Procedure in extreme cases) to unset the
immobiliser.
Arming the Security System
If the Radio Key fails to operate the security system, due to a depleted battery in the
Radio Key for example or its total loss/damage, the security system can be armed
using the Touch Key (alternatively the optional Keypad can be used, if supplied with
your system, see page 21). To do this open and leave open the vehicle’s door, briefly
press the Touch Key to the receptacle and remove it, the security system will arm
in the normal way (along with Door Open, Closed Loop & Auto-Arm Warning Bleeps if
switched on), immediately close the door and manually lock the door with the
vehicle’s door key.
Teaching New Touch Keys to the Security System
Touch Keys can be programmed into the security system using the Ignition PIN or
optional Keypad. Refer to pages 19 & 24 of this manual for details.
