Hyperfrequency Radar Module(Microwave Sensor) installation (7926)

FUNCTIONThe H.R.M. emits a microwave signal which forms adetection envelope within which any movement will resultin an alarm trigger. It is only active when the alarm isarmed and takes at least 15 seconds to stabilise andbecome active from arming. They are designed to beconcealed behind plastic or fabric trim, which do not affectmicrowave emissions.

INSTALLATIONBefore mounting the H.R.M. it is essential to establish theoptimum location. This is normally in the centre console,horizontally in between the back of the front seats, for 4seater vehicles.

In 2 seater vehicles the H.R.M. is best located at the front ofthe centre console facing back at an angle of 45 degrees.To do this, leave the H.R.M. until the rest of the installationis 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 is transmittedfrom the adjuster side of the H.R.M.

Note B: Microwave transmissions are blocked by metal, soconsole brackets, radios, seat frames etc. will affect theperformance of the H.R.M. The use of the vehicle must betaken into account, i.e. if the H.R.M. is mounted beneath acoin tray, the detection envelope will be completelychanged if the tray is subsequently filled with coins. It is,therefore, essential that the H.R.M. is not mounted behindany area which could possibly be covered by metal objectsin the normal use of the vehicle.

3. It may be necessary to move the H.R.M. or incline it toachieve desired coverage.

Note C: Two or more H.R.M.s may be required to coverlarger vehicles.

4. Mount in the optimum location using the bracketprovided.

5. If badly adjusted/positioned the H.R.M. may triggerfrom outside the confines of the vehicle. Always checkfor stray radiation through the windows and sunroof.

INSTALLATION NOTESNote 1: Be sure to secure the black plastic harness cover to

the back of the alarm to prevent water ingress and goodcontinuity between the harness plug and socket (seediagram 13).

Note 2: If additional cable is required, use only cable of thesame or greater current handling capacity.

Note 3: Ensure that all connections are electrically sound andmade through a suitable connector and protected fromwater ingress. Poor connections may cause erraticoperation of the alarm system.

Note 4: Take care to route cables away from the exhaust,cooling systems and any moving parts. Secure the alarm'sharness to original vehicle's harness or to a good fixingpoint of the vehicle.

Note 5: All alarm wiring should be lapped using tape ofsimilar appearance to the original vehicle. Extra tape maybe added to the vehicle's original harness to give similarappearance.

Note 6: The alarm circuit board includes special circuitbreakers which protect the main circuit board and theindicators from attack by shorting. The 15 Amp fuse in thealarm harness's power supply (Red wire) is to protect theharness from shorting due to poor installation. It isrecommended that the fuse holder and fuse is installed.

Note 7: Cable tie the ultrasonic and glass break cables to themain alarm harness siren each side of the 2-way connectorsto ensure they cannot be accidentally disconnected.

STATUS HISTORY - DIAGNOSTIC READ OUTIf the alarm has triggered in your absence you will be notifiedby the indicators flashing 4 times when the alarm is disarmed.The status history will then be displayed by a sequence offlashes from the alarm's LED. This will indicate the following:1 Flash Door, boot or bonnet opened2 Flashes Optional sensor trigger (Hyperfrequency

Radar Module - 7926HF)3 Flashes Ultrasonic sensor trigger or glass break trigger

(7928)4 Flashes Ignition sense - Ignition turned on while alarm

armed5 Flashes Voltage drop sensor triggered6 Flashes Tamper mode7 Flashes Serial line data link8 Flashes Serial line data link

MULTIPLE TRIGGERSThe alarm will also display multiple triggers, therefore if thedoor is opened and the ultrasonic then detects movementinside the vehicle the LED will display 2 flashes followed by 3flashes.

CLEARING DIAGNOSTIC MEMORY - STATUS HISTORYTurning the ignition �On' or arming the alarm system will clearthe Status History.

REMOTE KEY AND TOUCH KEYPROGRAMMING PROCEDURENote:i All Remote keys or Touch keys required to operate the

alarm system must all be programmed at the sametime. This includes all existing Remote/Touch keys aswell as new keys. Any Remote/Touch keys notreprogrammed at this point will not operate the alarmsystem.

ii You will require the unique Pin code number from thecustomer for this procedure. If the number has beenmisplaced it can be obtained by faxing the AlarmTechnical Help Line quoting the model number of thealarm and the alarm�s serial number which can befound on a white label under the alarm harness coveron back of the alarm.

iii A maximum of four Remote keys and four Touch keyscan be programmed into the alarm system.

iv If only Remote keys require programming it is notnecessary to re-code the Touch keys at this time andvice 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 Touch keys.A1 Press both buttons on the remote control until the

LED on the Remote key stops flashing (approximately10 seconds). On releasing the buttons the LED on theRemote key will illuminate.

A2 Repeat procedure A1 for ALL Remote keys required tooperate the alarm system. This includes existing andnew Remote keys.

Entering Pin Number:Each alarm system has a unique Pin Code number which

can be found on the card in the alarm box. This cardmust 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 the IgnitionON.

B3 Count the number of flashes until this is equal to the1st number of your Pin code (i.e. 2 flashes = No. 2, 4flashes = No.4) then turn the Ignition OFF and backON.

B4 Repeat procedure B3 for the following 3 digits of yourPin Code remembering to turn the Ignition OFF andback ON after each Code number.

B5 With the Ignition in the ON position, push an existingTouch key into its receptacle.IF Pin Number is correct the LED will illuminate.

Note: If at any time you fail while entering your Pin Code.Turn the ignition OFF for 10 seconds and start again.

PROGRAMMING REMOTE KEY/TOUCHKEYSRemote 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 for approximately 2seconds. The LED on the vehicle will flash to indicatethat the Alarm system has registered the codenumber.

C3 Repeat procedure C2 for All the Remote keys. (Thisalso 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 Alarm systemhas registered the code number.

C5 Repeat procedure C4 for all the Touch keys. (This alsoincludes all existing Remote keys).

Exit Programming Remote Key/Touch Keys & Test:

D1 Turn the ignition off. (This will exit programmingmode).

D2 Test all Remote keys and Touch keys.

Programming Remote Immobiliser:

Note: If the Immobiliser�s code number is greater than13122, Subract 13122 from the Immobiliser�s codenumber until the number is greater than 0 and less than13122.

i.e. Immobiliser Code 99999 = 08145 (13122 subtracted7 times)

i.e. Immobiliser Code 88888 = 10156 (13122 subtracted6 times)

(The code number must have 5 digits - therefore 875becomes 00875)

The procedure must be performed when the alarm is inthe UNSET condition:-

E1 Switch the ignition ON/OFF three times in five seconds.

E2 The LED will light for three seconds. Touch a touchkey once while the LED is on; the LED will switch offand the buzzer will sound for 1 second to indicate thebeginning of the immobiliser code auto-learningprocedure.

E3 Switch ON the ignition and count the blinking of LEDcorresponding to the first digit of immobiliser code;turn the ignition OFF.

E4 Repeat procedure E3 for the next 4 codes. To dial the�0� it is necessary to count 10 blinks of the LED (forexample: 234 will be 00234).

E5 After the 5th digit the LED will light for 2 seconds toconfirm the programming of the code.
