Where existing loop lead-in cable is present,the existing cable shall <br /> 35 be pulled out and disposed of. The new lead-in cable shall be spliced to the loop <br /> I <br /> 36 wires utilizing Buchanan splice caps and crimper and a scotch cast epoxy 82- <br /> 37 B1 splice kit or approved equal as detailed in City Standard Drawings 806A, B <br /> 38 and C. Where the wiring schedule in the plans calls for more than one loop <br /> 39 detector to be spliced into a single lead-in cable, the loops shall be wired in <br /> I 40 series. The loop detector lead-in cable shall be pulled into the controller cabinet <br /> 41 and connected to the detector channel terminals as indicated in the loop detector <br /> 42 schedule in the plans. <br /> I 43 <br /> 44 Loop Detector Lead-In Cable (2 or 3 pair) <br /> 45 <br /> I 46 Two or three pair loop detector lead-in cable shall be installed where shown in <br /> 47 the wiring schedule in the plans. Belden 1037A and 1055A cables are a pre- <br /> 48 approved source. Other cables may be submitted for approval consistent with <br /> 49 the following specifications: Multi pair loop detector lead-in cable shall consist of <br /> I50 two or three individually twisted and shielded pairs of#16 AWG stranded copper <br /> 51 wire, surrounded by an outer jacket of polyvinyl chloride (PVC).
