GENERAL HANDBOOK FOR HEIMDALL

DETECTORS

Doc. No.

667/HB/31900/000

5.7.4.4 Detector Height

The detector can be mounted at any height between 3.3m and 4m.

5.7.4.5 Detector Alignment – Default

The detector is aimed at an angle of 60 degrees from the horizontal, as shown in Figure

32 below. Adjustment of this angle is not recommended and will impact on detection

performance.

Figure 31 : Angle Notches in Heimdall Detector

The detector should point along the line of the kerb from its installed position; this should

allow detection up to and over the kerb.

At the closest point to the detector the zone is wider to take in the tactile paving, while the

thinner end of the detection zone stretches out to the end of the zone (Maximum 4m).

This can be altered using the DIP switch 6 under the side access panel, OFF is Long

zone (default) while ON shortens the end part of the zone for thinner crossings.

In Figure 32 the zone is shown with the wider part nearest the detector extending into the

road. This would pick up vehicles though the Heimdall software filters these out. This filter

has the side effect of making the near zone smaller, DIP switch 1 can be switched to 1 to

disable this filter in situations where the vehicle filter is not required and a wider near

zone is desirable.
