SR75H REMOTE CONTROL CAR ALARM SYSTEM 4
OPERATING YOUR SPARKRITE SR75H ALARM SYSTEMS
The radio remote control transmitter conforms to DTI legislation with each unit
allocated a unique security code. Additional remote controls are available on special
order from your nearest stockist or direct from Sparkrite using the enclosed order
form, quoting your serial number located on the back of the remote control.
ARMING YOUR ALARM
To arm the SR75H alarm system proceed as follows.
•Remove the ignition key and leave the vehicle, closing all doors, windows, sunroof,
boot and bonnet.
•Press the button firmly on the remote control. The siren will chirp once. The dash
mounted LED will illuminate to confirm the alarm has been armed.
•After a 20 seconds delay the LED will commence flashing to confirm that the system
is now fully armed.
When the alarm is armed, the current sensing and shock sensing circuits will not trigger the
alarm until a 20 sec exit delay has expired. This is to allow movement of the vehicle and in
some cases courtesy light to cease.
DISARMING YOUR ALARM
To Disarm the Alarm:
•Press the remote control transmitter button firmly once, the siren will chirp twice to
indicate the alarm has been disarmed.
•If you trigger the alarm accidentally, follow the normal disarming procedure keeping
the remote control button depressed until the alarm stops.
ENTRY ALERT
If when disarming the alarm the siren gives 3 chirps this indicates that the alarm has been
triggered in your absence. You should carefully check your vehicle before attempting to
drive away.
REMOTE PANIC
If you feel threatened outside of your vehicle and are within operating range you can trigger
your SR75H by holding the remote control button depressed for 3 seconds. This will
commence an alarm cycle of 30 seconds and draw attention to your situation and the
vehicle. The alarm can be silenced by pressing the remote control button again.

FITTING INSTRUCTIONS
IMPORTANT:
•Your SR75H is suitable for 12V negative earth vehicles only.
•Refer to Car Owners manual for the procedure for disconnection of your
battery before commencing the installation of this alarm.
•The vehicle battery must be disconnected during the installation procedure
except where it is necessary to carry out circuit testing specified.
•Vehicles fitted with digital radios having a security code or memory feature will
require re-programming on completion of the installation.
•Ensure you have noted the security code of your radio before disconnecting
the vehicle battery.
VEHICLE WIRING TESTING
If you are unable to easily identify the correct wire on the vehicle to make a
connection it is recommended a 12 volt test lamp or multi-meter is used. Care must
be taken to ensure that the wire being tested is not shorted out to earth by the test
lamp or multi-meter probes.
INSTALLATION NOTES
The wiring harness is supplied with an in-line (10 amp) fuse on the RED lead. If the
fuse blows, you must investigate the cause and replace with a fuse for the same
rating. When routing the harness around the engine compartment and through a
bulkhead inside the vehicle, ensure the wire’s insulation cannot be damaged on
sharp metal edges. The harness should be concealed and protected wherever
possible by using good quality insulation tape. It is recommended that wherever
possible connection to the vehicle wiring is carried out at the steering column or at
the fuse box. This will prevent tampering from outside the vehicle.
MAKING RELIABLE CONNECTIONS
All connections in the engine bay area must be made using either solder joints or
good quality crimp termination’s.
WARNING: The use of Insulation Displacement Connectors such as scotchlocks
(IDC’s) is not recommended in the engine bay area. The use of IDC’s in this area
may result in the alarm failing to operate correctly or cause false alarms.
IDC connectors can be used inside the vehicle, but you must follow the instructions
below to ensure a reliable connection.

SR75H REMOTE CONTROL CAR ALARM SYSTEM 6
USING IDC CONNECTORS
1) Choose the correct size connector that suits the alarm and the vehicle wire
diameter.
2) Place the wires in position as shown in the Fig.1 and hold in place whilst
firmly pressing in the metal inserts with pliers. The metal insert will then
automatically strip the insulation from both wires at the point of contact.
3) Close the locking tab to hold the connector together as in Fig.2.
4) Ensure that the vehicle wire and alarm wire is positioned where they cannot
be snagged by vehicle controls or the drivers and passengers feet.
Fig1 Fig 2
MOUNTING THE MAIN ALARM MODULE
Locate a mounting position for the alarm in the vehicle engine compartment close to
the front of the vehicle and in a position where it is difficult to again access to the
alarm wiring from below the car.
Ensure that the alarm is located away from extreme heat, areas subject to water and
at least 12” from the ignition system. (Use silicone sealant enclosed when refitting
boot).
Using the alarm bracket as a template, drill 2 holes and secure the bracket to the car
body-work using the self tapping screws provided making sure the alarm bracket is
solidly mounted. Check behind any panels for hidden pipes or wiring before
drilling holes. Secure the alarm to the bracket using the small bolts supplied
making sure that front face of the alarm is kept vertical (facing the front of the
vehicle) to ensure effective operation of the shock sensor.

HARNESS LOCATION
Position the harness to the rear of the main alarm module and secure where
necessary to the vehicle wiring using insulation tape.
Plug in the main harness connector to the rear of the alarm unit. Do not fit the
rubber boot to the alarm at this stage.
You can now make connections to the car wiring as shown ALL the wires must be
connected in the order outlined in these instructions.
SR75H WIRING CONNECTIONS

SR75H REMOTE CONTROL CAR ALARM SYSTEM 8
ARMED INDICATOR LED
Remove the retaining nut from the LED bezel. Drill a suitable
mounting hole in the dashboard where the indicator may be seen
from the exterior of the vehicle as a visible deterrent. Feed the two
way connector and wire through the hole and secure the LED with
the retaining nut (see Fig.3). Route the wire through a bulkhead
grommet to the alarm and push it carefully through the flexible
rubber boot. Insert the two way connector from the LED into the
socket on the rear of the alarm unit.
GREEN WIRE-ALARM ANTENNA
The GREEN antenna wire must not be cut or connected to anything
metal otherwise the alarm operating range will be affected. Extend
the GREEN wire and secure to the outside of the wiring harness to
achieve optimum performance. Ensure the wire cannot come into
contact with a hot surface, bare metal or immersed in water.

SR75H REMOTE CONTROL CAR ALARM SYSTEM

YELLOW WIRE-ELECTRIC FAN INHIBIT
IMPORTANT: If you have a mechanical cooling fan or the electric
fan does not operate with the ignition turned off, then
the yellow wire MUST be connected to a good
earthing point BEFORE connecting the RED wire of
the alarm.
If the electric cooling fan still operates when the ignition is turned
OFF then a connection from the SR75H must be made to prevent
the current sensing function from false triggering the alarm. The
cooling fan wiring will be configured as shown in Fig. 4 or 5.
NOTE: The engine must be cold before proceeding.
Locate the fan thermal switch by tracing the wiring from the fan
motor. Connect the YELLOW wire as shown in Fig. 4 or Fig. 5 using
a solder joint or a crimp termination to the wire which runs between
the fan motor and thermal switch.
Fig4 Fig 5
BLACK WIRE-EARTH
The BLACK wire must be connected to a good clean metal earthing
point on the body-work of the vehicle. Drill a suitable hole near the
main alarm unit and secure the BLACK wire through the ring
terminal.
NOTE: Do not mount the BLACK earth wire on the alarm bracket
as the anti-corrosion paint will prevent a good earth
contact. If in any doubt the BLACK earth wire can be
connected direct to the battery negative terminal.

SR75H REMOTE CONTROL CAR ALARM SYSTEM 10
RED WIRE-POWER SUPPLY AND CURRENT SENSING
The SR75H is triggered by the operation of the interior light or any
electrical circuit on the vehicle. This is detected by the RED power
supply wire. The trigger sensitivity will vary from vehicle to vehicle
depending on size and age of the car battery and the rating of the
interior light bulb. As a general principle the sensitivity will increase
the further from the battery the main supply connection is made. For
optimal operation the interior light bulb should be rated at 10 watts
minimum. To determine the best connection point a simple test
procedure should be followed as below.
1) Temporarily connect the RED wire to the battery positive
terminal.
2) Close all doors, boot and bonnet then arm the alarm with the
remote control.
3) Wait at least 20 seconds then open any door. If the alarm
triggers you can make the connection to the battery positive
(+) terminal permanent.
4) If the alarm fails to trigger during step 3 disconnect from the
battery and route the RED alarm wire to the fuse box and
repeat the test using permanent live at the fuse box, following
steps 2 and 3 as above.
5) When the test is successful make your connection
permanent.
ORANGE/WHITE WIRE-CENTRAL LOCKING CONTROL
This is only applicable for vehicles that have central locking as a
standard feature. Do not attempt to directly connect
ORANGE/WHITE wire to any part of the vehicle central locking
system. The ORANGE/WHITE wire must only be connected to the
optional Sparkrite SR911 Central Locking interface. This will allow
the vehicle doors to be locked and unlocked by the alarm remote
control. If this feature is not used, insulate the wire and secure it in
a safe position.

SR75H REMOTE CONTROL CAR ALARM SYSTEM
11
BOOT AND BONNET SWITCHES
If your vehicle is not fitted with Boot/Bonnet switches which operate
the interior light these switches are available from Sparkrite as an
accessory kit. The Switch Kit (Part No. SR910) should be installed
and connected as shown in Fig. 6. Ensure the fixing screw for the
switch makes a good earth contact, crimp a piece of wire to the
switch terminal and then connect into the existing interior light
circuit.
Fig 6
SHOCK SENSOR
The SR75H includes an electronic shock sensing device to detect
sudden impact or shock transmitted through the body-work of the
vehicle. Fig 7
The sensitivity adjuster is located on the rear of
the main alarm unit.
To set the shock sensor adjustment:
1) Remove the adjuster blanking plug, arm the alarm and wait
for the 30 second arming period to elapse.
2) Starting with the adjuster at minimum, progressively increase
the sensitivity using a SMALL flat bladed screw driver, until
the shock sensor detects a sharp blow to the centre of the
windscreen with the flat of the hand triggering the alarm.
3) Refit the adjuster blanking plug to prevent water ingress.
NOTE: Do not set the shock sensor at a higher than necessary
setting otherwise false alarms will result. If a bonnet
switch is fitted please ensure that the switch is held closed
(or disconnected) to eliminate the circuit whilst adjusting
this feature.

SR75H REMOTE CONTROL CAR ALARM SYSTEM 12
TESTING THE ALARM INSTALLATION
1) Check all connections are secure and the vehicle battery is connected.
2) Press the remote control button. The alarm will arm with one chirp.
3) Press the remote control button. The alarm will disarm with two chirps.
4) Arm the alarm. Wait approximately 20 seconds, open a door ensuring the
interior light operates. The alarm will trigger. Disarm the alarm. (Refer to
trouble shooting section if alarm fails to trigger).
5) Repeat the arming procedure and trigger via shock sensor, disarm alarm.
6) Test remote panic features by holding down the remote control button for 3
seconds. The alarm will trigger. Release button and press again to disarm
the alarm. If problems are encountered, refer to the trouble shooting guide
before proceeding further.
Finally ensure that all wiring is neatly secured/insulated where necessary and fuses
etc are checked for safety.
Install the window warning labels on the passenger windows and make a note of
your remote control serial number in the space provided on page 14.
Installing the Waterproof Rubber Boot
To protect the alarm from water ingress, the rubber boot must be installed using
Silicone Sealant (supplied) and should be applied as follows:
CAUTION:
Uncured sealant irritates eyes. In case of contact wash with water and consult your
doctor.
Avoid prolonged skin contact. Acetic acid fumes are released during curing, ensure
adequate ventilation is provided.
Firstly, clean all surfaces thoroughly. Apply a thin even bead of silicone around the
outer lip of the back alarm moulding, The remaining silicone will now be applied
down the narrow section of the rubber boot. The silicone should be worked between
and around the wires ensuring ample coverage. Once the silicone is in place a tie
wrap (supplied) should be fastened around the narrow section of the rubber boot.
The tie wrap will force part of the silicone back out of the rubber boot, this excess
should NOT be wiped/cleaned away, but worked back into the boot.
The silicone sealant will be fully cured after 24 hours.
Complete the installation by neatly securing the alarm wiring harness using tie wraps
and/or insulation tape.
WARNING: Failure to carry out these instructions will result in water ingress, false
alarms and will invalidate any warranty claim.
