ETECTOR ANDBOOK INSTALLATION OF TRAFFIC LOOPS AND FEEDER CABLES IN SLOTS Before the work is carried out, the tools listed in the General Principles Installation handbook (see section 1.3.1) should be available. Loop Cable and Slot Dimensions Loop slots are cut into road surfaces for the installation of the following loop cables: 998/4/70671/001 50/0.25 EPR insulated...
ETECTOR ANDBOOK However, in the case of SDE/SA loops, the presence of an isolated heavy metal object can distort the electromagnetic effect of one of the pair of loops so that a false speed assessment is given. In these cases it is necessary to re-site the loops 1 metre away from such objects.
ETECTOR ANDBOOK 2.2.7 Feeders Sharing of a multi-pair feeder cable between different detectors is not recommended. See section 2.7 for feeder types. Loop Configurations Loop positions will be marked prior to slot cutting, as per the positioning instructions shown on the STS. Loop configurations are normally of the following types: Chevrons - Vehicle actuation, SDE/SA...

2.3.8 Turning Loops and SDE/SA Loops Figure 8 to Figure 10 illustrate configurations for turning loops, and SDE/SA loops. The turning loop Figure 9 can be connected to Siemens/Plessey, Microsense and Sarasota detectors observing the calculation for loop turns listed in section 2.5 of this document.
Figure 13 illustrates queue loops and special purpose loops whereby fixed and limits of variable dimensions are shown. These loop configurations can be connected to Siemens/Plessey, Microsense and Sarasota detectors observing the calculations for loop turns as listed in section 2.5 of this handbook.
ETECTOR ANDBOOK Cable Laying and Slot Backfilling Procedures 2.6.1 Loop Cable Laying The loop cable should be dry. Loops are laid starting at the kerb, running the tails out winding the loop and returning via the same slot to the kerb. When winding a multiple diamond loop, the cables must cross at the point where the diamonds meet.
ETECTOR ANDBOOK The feeder cable is supplied with 1.5 mm or 2.5 mm copper conductors and may be manufactured with or without steel wire armour to meet customer specification. The referred types are 1 or 2 pair non-armoured cables with 1.5 conductors and an orange coloured outer covering.
ETECTOR ANDBOOK Backfilling shall be with fine cold asphalt rammed into the slot and finished with a surface layer of hotpour of 20 mm nominal depth. Joint Loop Tails to Feeder Cables STC approved joint is the acrylic joint to specification 915/4/03118/etc. These joints can be used in underground chambers, soil and encapsulated in slots in carriageways.
ETECTOR ANDBOOK 2.11 Loop Detector Settings 2.11.1 Sensitivity For normal VA purposes the detectors should be set to give bicycle detection. This requires a sensitivity setting of 0.01% or 0.02%. If the setting is too sensitive the detector will be unduly sensitive to vehicles in adjacent lanes. This is most likely where a single small loop is installed on a detector channel i.e.

ETECTOR ANDBOOK CABLING This section applies to paired loop feeder cable and multicore cable to Detector Pole Boxes and Signals Heads. Cabling and Preparation of Cables for Termination 1. Traffic intersections are cabled in accordance with the schedule shown on the STS drawing.
ETECTOR ANDBOOK Remove the outer insulation and break off the armour by repeated bending. Cut through the outer insulation 50 mm from the end of the armour without cutting into the armour. Remove outer insulation. Terminate the bedding so that 10 mm projects beyond the armour. Slide a worm drive hose clip over the cable.
ETECTOR ANDBOOK Cut the stepped ends of the shell halves so that they fit over the outer insulation of the cable and the bundle of detector loop tails without interference but, at the same time, giving minimum clearance in order to avoid eccentricity.
ETECTOR ANDBOOK CAUTION: Certain individuals are susceptible to sensitisation and if a skin rash develops medical advice should be sought. Any resin splashes on the skin should be removes before the resin hardens. 3.2.4 Feeder Cable to Detector Loop Tails using the Heatshrink Joint The part number of the kit to be used is 667/4/15084/etc.
Page 45
ETECTOR ANDBOOK Prepare the feeder cable as detailed for the type of joints and the joint kit to be used. Cut the conductors to length ensuring that the joints will be staggered within the joint shell. The outer sheath must project at least 50 mm into the joint shell in the finished joint and no crimp joint should be closer than 75 mm to the end of the shell.
