l Switching for electric central door locking systems.l An LED indicator light provides a visual indication

when the alarm system is armed. It will also displaytrigger codes if the alarm has been triggered in yourabsence.

l A safety circuit ensures that the alarm cannot bearmed while the vehicle's engine is running.

l Panic alarm.l Ultrasonic exclusion from radio key.l Optional microwave sensor exclusion from radio key.l Self learning radio keys.l Touch key override.l Door open warning.l Switching for �Total Closure� window or sunroof

closing system.

INSTALLATION NOTESAlarm Unit:l Mount the alarm unit with the screws provided in a

suitable position in the passenger compartment.l The active range of the radio key transmitter is

approximately 3 metres but may vary dependingon the type of vehicle and prevailing weatherconditions.

l Mount the Emergency Touch Override Receptacle ina location that is accessible. This may be in aswitch blank, dashboard, glove box etc.

l Mount the ultrasonic transmitter and receiver unitsinside the vehicle and position them to scan themaximum internal area of the vehicle. They shouldnot be positioned near air vents. The top of each �A'pillar is the normal position for the ultrasonictransmitter and receiver units, being careful thatthey are not fouled by the sun visors.

CENTRAL DOOR LOCKINGCOMMANDS

Confirm the type of door locking system the vehiclehas and connect using the appropriate application.

1. Single Point Locking System:For vehicles fitted with a single point lockingsystem (central door locking system can only beoperated from the driver�s door). Fit the door motorand connect as shown in diagram 8. Connect theViolet/Orange to a positive supply via a fuse holderand 7.5 Amp fuse. The alarm is preset for a 1second output on the Violet & Orange wires (Lock/Unlock).

2. Negative Command Door Locking System:For vehicles fitted with a negative command centraldoor locking system connect as shown in diagram9. The alarm is preset for a 1 second output on theViolet & Orange wires (Lock/Unlock).

3. Positive Command Door Locking System:For vehicles fitted with a positive command centraldoor locking system connect as shown in diagram11. Connect the Violet/Orange to a positive supplyvia a fuse holder and 7.5 Amp fuse.

4. Direct Motor Control:For vehicles which require the alarm to directlypower the existing door motor wire to operate thecentral door locking system, connect as shown indiagram 10. For this to operate correctly the doormotor wires must be negative while the motor is inthe rest position.

INSTALLATION NOTESNote 1: If additional cable is required, use only cable of

the same or greater current handling capacity.Note 2: Ensure that all connections are electrically sound

and made through a suitable connector and protectedfrom water ingress. Poor connections may causeerratic operation of the alarm system.

Note 3: Take care to route cables away from the exhaust,cooling systems and any moving parts. Secure thealarm's harness to original vehicle's harness or to agood fixing point of the vehicle.

Note 4: All alarm wiring should be lapped using tape ofsimilar appearance to the original vehicle. Extra tapemay be added to the vehicle's original harness to givesimilar appearance.

Note 5: The alarm circuit board includes special circuitbreakers which protect the main circuit board and theindicators from attack by shorting. The 15 Amp fuse inthe alarm harness's power supply (Red wire) is toprotect the harness from shorting due to poorinstallation. It is recommended that the fuse holder andfuse is installed.

Note 6: Cable tie the ultrasonic and glass break cables tothe main alarm harness siren each side of the 2-waycvonnectors to ensure they cannot be accidentallydisconnected.Diagram 10

Optional HRM - Hyperfrequency RadarModule (Microwave Sensor) InstallationFUNCTIONThe H.R.M. emits a microwave signal which forms adetection envelope within which any movement willresult in an alarm trigger. It is only active when thealarm is armed and takes at least 15 seconds tostabilise and become active from arming. They aredesigned to be concealed behind plastic or fabrictrim, which do not affect microwave emissions.

INSTALLATIONBefore mounting the H.R.M. it is essential to establishthe optimum location. This is normally in the centreconsole, horizontally in between the back of the frontseats, for 4 seater vehicles.

In 2 seater vehicles the H.R.M. is best located at thefront of the centre console facing back at an angle of45 degrees. To do this, leave the H.R.M. until the restof the installation is complete, then:

1. Connect up the H.R.M.

2. Place the H.R.M. in your preferred location and gothrough the set-up procedure.

Note A: The microwave detection envelope istransmitted from the adjuster side of the H.R.M.

Note B: Microwave transmissions are blocked bymetal, so console brackets, radios, seat frames etc.will affect the performance of the H.R.M. The use ofthe vehicle must be taken into account, i.e. if theH.R.M. is mounted beneath a coin tray, the detectionenvelope will be completely changed if the tray issubsequently filled with coins. It is, therefore,essential that the H.R.M. is not mounted behindany area which could possibly be covered by metalobjects in the normal use of the vehicle.

3. It may be necessary to move the H.R.M. or inclineit to achieve desired coverage.

Note C: Two or more H.R.M.s may be required tocover larger vehicles.

4. Mount in the optimum location using the bracketprovided.

5. If badly adjusted/positioned the H.R.M. maytrigger from outside the confines of the vehicle.Always check for stray radiation through thewindows and sunroof.

Note:i All Remote keys or Touch keys required to operate

the alarm system must all be programmed at thesame time. This includes all existing Remote/Touch keys as well as new keys. Any Remote/Touchkeys not reprogrammed at this point will notoperate the alarm system.

REMOTE KEY AND TOUCH KEY PROGRAMMING PROCEDURE

ii You will require the unique Pin code number fromthe customer for this procedure. If the number hasbeen misplaced it can be obtained by faxing theAlarm Technical Help Line quoting the modelnumber of the alarm and the alarm�s serial numberwhich can be found on a white label under thealarm harness cover on back of the alarm.

iii A maximum of four Remote keys and four Touchkeys can be programmed into the alarm system.

iv If only Remote keys require programming it is notnecessary to re-code the Touch keys at this timeand vice versa.

Procedure for Programming/Re-Programming:A Remote key preparation.B Entering the Pin number.C Programming the Remote keys/Touch keys.D Exit programming and test.Remote Key Preparation:This procedure is not required to program Touchkeys.A1 Press both buttons on the remote control until the

LED on the Remote key stops flashing(approximately 10 seconds). On releasing thebuttons the LED on the Remote key willilluminate.

A2 Repeat procedure A1 for ALL Remote keysrequired to operate the alarm system. Thisincludes existing and new Remote keys.

Entering Pin Number:Each alarm system has a unique Pin Code numberwhich can be found on the card in the alarm box. ThisCard must be given to the customer on delivery of thevehicle.B1 Turn the Ignition ON and OFF 3 times within 7

seconds.The LED will Illuminate for approx. 3 seconds.

B2 Immediately the LED extinguishes, switch theIgnition ON.

B3 Count the number of flashes until this is equal tothe 1st number of your Pin code (i.e. 2 flashes =No. 2, 4 flashes = No.4) then turn the Ignition OFFand back ON.

B4 Repeat procedure B3 for the following 3 digits ofyour Pin Code remembering to turn the IgnitionOFF and back ON after each Code number.

B5 With the Ignition in the On position, push anexisting Touch key into its receptacle.IF Pin Number is correct the LED will illuminate.

Note: If at any time you fail while entering your PinCode. Turn the ignition OFF for 10 seconds and startagain.

PROGRAMMING REMOTE KEY/TOUCH KEYSRemote Keys:C1 Ensure that you have prepared the Remote keys

for programming (see procedure A1 and A2).C2 Press either of the buttons on the remote control.

The LED on the Remote key will flash forapproximately 2 seconds. The LED on the vehiclewill flash to indicate that the Alarm system hasregistered the code number.

C3 Repeat procedure C2 for all the Remote keys.(This also includes all existing Remote keys).

Touch Keys:C4 Press the Touch key into its receptacle. The LED

on the vehicle will flash to indicate that the Alarmsystem has registered the code number.

C5 Repeat procedure C4 for all the Touch keys. (Thisalso includes all existing Remote keys).

Exit Programming Remote Key/Touch Keys andTest:D1 Turn the ignition off. (This will exit programming

mode).D2 Test all Remote keys and Touch keys.
