5.5.4.6 Detector Alignment Optional
With this optional method, the detector uses a combined ‘movement and static’ detection
algorithm. In this case the detector is aimed slightly towards oncoming traffic and towards
the centre of the centre of the carriageway, as shown in Figure 19 below.
To use this installation method, use configuration DIP switch 6 (set to ‘1’), or using the
appropriate terminal command ‘DAA’ set to ‘1’, to activate the combined ‘movement and
static’ detection algorithm

.
For optimum performance, this alignment is not recommended. However, this alignment
can be used where the users would prefer to limit detection to vehicles moving towards
the detector and a drop in detection performance is acceptable. This may also be of use
on installations, for example, with very narrow lanes.
