The Acumen SCOOTER consists of the following main
components;

• SCOOTER main unit ECU (Electronic Control Unit)

• SCOOTER wiring harness

• 1 x Remote Fob

• Fitting kit including System fuse, spare fuse & Red LED system
indicator

Tool Required:

• Pliers/Cable strippers/Cable cutters

• Drill with 5.5mm and 8mm bits

• Soldering equipment

• Adhesive lines heatshrink tubing

• High quality insulating tape

• Masking tape (for drilling LED hole)

• Multimeter

• General workshop tools

• 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
washing.

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.

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

Connect the system wires as
follows:

A larger version of the wiring diagram
can be found on the back page.

The

RREEDD

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

BBLLAACCKK

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

BBRROOWWNN

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
soldered.
