Scooter wiring diagram
SCOOTER main unit ECU (Electronic Control Unit)
Ensure the fitting of the equipment and the associated wiring does not
affect the operation of the scooter. Be sure the alarm and wiring does not
affect moving parts (such as control cables, brakes) and does not touch
hot parts.
The SCOOTER is designed for scooter use and is fully encapsulated so
water ingress is not of a concern. Likewise, the Key Fob is also of a
waterproof design. We recommend however that the unit is not placed in a
position where it is continually subjected to water and/or pressure
Siting/positioning the SCOOTER main unit/ECU (Electronic Control unit)
When mounting the unit, use the 5mm screws/nuts supplied in the fitting kit
or cable tie the unit to a suitable frame tube. Take care to mount the unit
where access to it is protected (the more difficult it is to reach, the harder
the job the ‘thief’ has to bypass the alarm).
Route the wiring alongside the scooter wiring, and tape it in the style of the
original scooter wiring.
Siting/positioning the LED system Indicator
Be aware the LED will result in a small increase of electrical current drain.
The LED draws 1mA of electrical current. The LED provides a visual
indication of the alarm’s status, helps with the diagnostic mode of the
alarm, and will warn a potential thief that your scooter is alarmed and that
the alarm is armed.
For this reason, it is preferable to position the LED where it can be easily
seen. Having decided on a suitable position, drill an 8mm hole, pass the
LED through from the back of the hole and then insert the LED into the LED
holder. Then push the LED holder back into the 8mm hole to mount it
securely. Route the LED wires to the position of the SCOOTER ECU.
The alarm has a loom which ends in a 6-way connector. This connector
connects to the wiring loom which is connected to the scooter.
Installation and Wiring
To make the alarm active, you only need to connect the
Red, Black and Brown wires
Connect the system wires as
A larger version of the wiring diagram
can be found on the back page.
The RED wire is the alarm positive feed.
DO NOT connect this directly to the
scooter battery, but connect to the
positive terminal of the starter solenoid.
Use the Red-tagged ring terminal from
the fit kit.
The BLACK wire is the alarm negative
connection. Connect this wire to a
suitable earthing point on the scooter
frame. DO NOT connect to the battery
negative terminal. Do NOT connect it to a
sub-frame or fairing-frame. An ideal spot
is the connection of the scooter battery
negative lead & frame. Use the Bluetagged ring terminal from the fit kit.
The BROWN wire should be connected
to a circuit which becomes live when the
ignition is switched on. Ideally, this
should be connected between the
ignition switch and the scooter fuse box.
If this is not practical, a good place is the
feed to the rear brake light switch.
Acumen recommends this connection is
Connect the 6-way connectors together
and proceed to Operation
To get full basic operation of the SCOOTER System, Acumen recommends
that you also connect the PINK (indicators) and Black/Red (LED) wires (see page 3)
Should you require further options on the CAT 3 system, please see the Optional Wiring (see page 3)
Optional Wiring
Acumen recommends that the following wires are connected to get full
basic operation of the SCOOTER System, however, they are not critical to
the operation of the system.
Flashing Indicators
The two PINK wires are for the indicators. Connect one Pink wire to the LH
indicator, and the other Pink wire to the RH indicators. Ensure you connect
these wires to the positive side of the indicators - if you connect to the
negative side of the indicators the alarm fuse will fail. Acumen recommend
these connections are soldered.
Flashing LED
The paired Black/Red wires with the two-way connector are for the LED
system indicator. Connect the two plugs together.
Movement Sensing Nudge Facility
The two BLUE wires - one with a male connector on it, one with a female
connector - are to remove/add the nudge facility of the movement sensing.
If the two blue wires are connected, the nudge sensing is added.
Dis-connecting these two wires removes the nudge sensing.
Optional Wiring Connections
(not required for basic operation)
The YELLOW/GREEN wire is the Pager wire. It supplies 12v at 0.5A when the
alarm is reacting. It is designed to connect to the Acumen AlarmMate Pager
(Acumen Pt No 10114) and/or the Acumen external siren (Acumen Pt No
10115) .
If this wire shorts to Ground while the alarm is sounding the alarm ECU will be
The PURPLE wire is the alarm antenna. It should be extended along a plastic
component and taped into position. Do not tape within the wiring harness and
do not connect to ground/earth.
The GREEN wire is the trigger wire for the optional Immobilisation relay.
Instructions for connection are included in the immobilisation kit. If you are
not using it, tape the wire to the main harness in a tidy fashion.
The WHITE wire is an optional Trigger wire. If you need to use this circuit, the
alarm will trigger if the switch you add to this circuit changes it’s state. (ie;
open to closed, or closed to open) Connect the wire to a switch and the other
side of the switch to a suitable ground. When the switch changes the alarm
will sound. It can be connected to items such as a magnetic reed seat switch,
or pressure mat under the m/c side stand, or the Acumen garage kit.
NOTE If a poor connection is made in this circuit the alarm will interpret any
change of state - regardless of how short in time - as an alarm and will react
accordingly. Make sure all connections are sound, waterproof and cannot
The visual indications are based on the assumption that the Pink
wire (Indicators) and the Black/Red wires (LED) have been
connected (See page 3).
The standard key fob has three buttons; Lock, Unlock and Silent.
To Arm the system.
Convenience (Ferry) Mode
In Convenience mode the movement/nudge sensor will cease to function.
With the alarm active, press the Silent button. You will get one long tone and
one flash of the indicators.
If the LED flashes once/per second the movement sensing is active
If the LED flashes once every two seconds, the movement sensing is disabled.
You can ‘toggle’ between Convenience Mode enabled and disabled by simply
pressing the silent button.
Press the Lock button of the fob. The alarm will beep twice and
flash the indicators twice. The system LED will start to flash after 5
seconds and the unit will monitor hot-wire, accessory switch,
movement and nudge. (The system will not arm if the ignition is
switched on).
Diagnostics Mode
To Disarm the system.
a. When the alarm is sounding the LED will flash a number of times, pause,
then flash the same number again. This will go 30 seconds until the
system stops sounding.
Press the Unlock button. The system will give one short beep and
flash the indicators once.
NOTE If the system gives one long beep this means the alarm has
been sounding. Enter diagnostics mode to find the reason why.
It is possible to determine the trigger source that caused the alarm to sound.
Only the last reason is recorded.
Diagnostic mode can be accessed two ways;
b. Alternatively, disarm the alarm and then press the silent button. The LED
will flash a number of times and the system will beep the same number of
times. Every time you press the silent button the system will flash/beep in
accordance with the following table.

Spares and Accessories
The alarm will not react to the fob
Check the fob batteries (type CR2016).
Place the fob as near as possible to the alarm
system main unit. If it will now disarm there
are probably spurious radio signals in the
vicinity. Move the scooter to another area.
Acumen can supply a range of spares &
accessories to enhance the features of the
SCOOTER system:
Spare and replacement remote fobs and
The key fob can be up-graded to the same flipfob as used on the Acumen ‘Thatcham’
specification CAT1 and CAT21 systems. The Flipfob uses Microchip KeeLoq® code-hopping
technology which prevents scanning and
recording of transmitter codes. When ordering,
specify Acumen part number 51020 and your
make, model and year of scooter.
Check the system fuse. If the alarm has no
power it cannot power the radio receiver.
Switch on the scooter ignition - if it disarms
now the alarm’s power supply is at fault (fuse
or connections).
False alarms.
Remember! The alarm may think it is being stolen,
which is different to it being faulty!
Enter Diagnostic mode and find out why the
alarm is/was reacting.
Take appropriate action - such as:
Enter Convenience Mode if it’s a windy
day (see page 4).
Check earth/power connections if you
repeatedly get a ‘power interrupted’
3. The alarm fuse keeps failing.
The system cannot ‘blow’ the fuse. It is what the
alarm switches that blows the fuse - usually the
indicators. Make sure there are no shorts in the
indicator system and if a new fit, make sure the
alarm PINK wire(s) is/are not connected to the
negative side of one, or both of the m/c indicators.
NOTE The Acumen SCOOTER cannot ‘know’ both
types of fob at the same time. If it ‘knows’ the
standard fob, it cannot ‘know’ a flip fob at the same
time. It can ‘know’ 2 x standard fobs at the same
time, or 2 x flip fobs at the same time, but not 1 of

General Security Precautions.
While the Acumen SCOOTER provides state of the
art electronic security and protection, it will not, by
itself, ensure your scooter will not be stolen. We
recommend you undertake basic security
precautions such as;
Parking in a locked garage if possible,
Parking in well lit areas if a garage is not
Using a bike cover where appropriate,
Using a chain or shackle and ground anchor.
