5.7.4 Detector Installation Instructions

Note: There must be no obstruction between the front face of the detector and the

detection zone, i.e. no obstruction by backing boards, signal aspects or foliage. Foliage

such as trees and bushes that are within the detection zone, will mean there is a risk of

false detects and possibly Permanent or no detect situations

Failure to adhere to these recommendations will reduce detector performance

5.7.4.1 Standard Detector Installation - Recommended

The standard traffic pole with the head mounted to one side is a suitable installation

scenario, where the aspect (traffic light) is mounted to one side of the detector location

and therefore provides for a clear view of the expected detection area.

In this situation the Kerbside should be mounted with the standard Kerbside mounting

bracket, which ensures the correct mounting distance in front of the nearside. The user

should reference Table 9-1 - p105 for part numbers.

Use of this bracket assumes that the pole has been installed with its mounting holes in

parallel to the kerb; if this is not the case then please see section 5.7.4.3.

Figure 25, below, illustrates the recommended detector and aspect configuration for all

new site installations that require a Heimdall detector Kerbside.
