The new lead-in cable shall be spliced to the loop wires utilizing <br /> 34 Buchanan splice caps and crimper and a scotch cast epoxy 82-B1 splice kit or <br /> 35 approved equal as detailed in City Standard Drawings 806A, B and C. Where,the <br /> I <br /> 36 37 wiring schedule in the plans calls for more than one loop detector to be spliced into <br /> a single lead-in cable, the loops shall be wired in series. The loop detector lead-in <br /> 38 cable shall be pulled into the controller cabinet and connected to the detector <br /> I <br /> 39 channel terminals as indicated in the loop detector schedule in the plans. <br /> 40 <br /> 41 Loop Detector Lead-In Cable (2 or 3 pair) <br /> 42 <br /> I 43 Two or three pair loop detector lead-in cable shall be installed where shown in the <br /> 44 wiring schedule in the plans. Belden 1037A and 1055A cables are a pre-approved <br /> 45 source. Other cables may be submitted for approval consistent with the following <br /> I 46 specifications: Multi pair loop detector lead-in cable shall consist of two or three <br /> 47 individually twisted and shielded pairs of #16 AWG stranded copper wire, <br /> 48 surrounded by an outer jacket of polyvinyl chloride (PVC). Each pair shall also <br /> 49 contain a stranded copper drain wire and shall be individually shielded with an <br /> 50 aluminum polyester foil shield. <br /> 51 <br /> I 2020 PAVEMENT MAINTENANCE OVERLAY PAGE 71 OF 79 SPECIAL PROVISIONS <br /> WORK ORDER 3727 FEBRUARY 20,2020 <br />
