Installation guide
Halo Touchless Car Operating System
Step 1: sensor location
Decide where to place Halo sensor, line up positioning
guide on faceplate and use it to drill the fixing holes.
Note: the Halo sensor has a maximum range of 320mm in
the X axis - do not mount sensor further than 320mm from
pushbuttons.
The metal positioning guide is the same footprint as the Halo
unit. It can be used for left and right fitment, allowing for
easy placement.
If the customer requires a symmetrical layout, we offer the
option of installing two Halo units. The second unit will not
contain a sensor and can be sold with the same print on the
side, or without print.
Steps 1 & 2 only apply if your Halo is being fitted to an existing car operating
panel (COP) faceplate. Otherwise, please proceed to step 3.

(c) Small laser-cut arrow:
indicates where to begin
your measurements.
This will be known as
the ‘0 point’ of the
X and Y axes.

Step 2: measurements
Take button measurements & send to supplier for
programming (see programming guide).
Use the laser cut arrow on the positioning guide as the 0
point of the X and Y axes. Measure from both axes to the
centre of your buttons, as shown in the diagram. Using
the table below as a guide, take measurements for all
buttons and submit for programming (please download
programming form).
You will not be able to proceed with the following steps until steps 1 & 2 have
been completed and you have received your programmed Halo sensor.
Step 3: Halo attachment
Attach Halo sensor to the faceplate, with connector
passing through the 10.5mm hole.

Step 4: CPU & 8 way call card attachment
Attach the CPU & 8 way call card to the
rear of the COP faceplate.
Step 5: wiring
Insert ribbon cable into the CPU board as shown.
Please observe the orientation.
CPU board 8 way call card
Insert ribbon cable into Halo
sensor and close black tab.
Connect CPU board to 8 way call card,
then wire this to your pushbuttons.
