The new lead-in cable shall be spliced to the loop <br /> 35 wires utilizing Buchanan splice caps and crimper and a scotch cast epoxy 82- <br /> 36 B1 splice kit or approved equal as detailed in City Standard Drawings 806A, B <br /> 37 and C. Where the wiring schedule in the plans calls for more than one loop <br /> 38 detector to be spliced into a single lead-in cable, the loops shall be wired in <br /> 39 series. The loop detector lead-in cable shall be pulled into the controller cabinet <br /> 40 and connected to the detector channel terminals as indicated in the loop detector I <br /> 41 schedule in the plans. <br /> 42 <br /> 43 Loop Detector Lead-In Cable (2 or 3pair) <br /> 44 <br /> 45 Two or three pair loop detector lead-in cable shall be installed where shown in <br /> 46 the wiring schedule in the plans. Belden 1037A and 1055A cables are a pre 111 <br /> - <br /> 47 approved source. Other cables may be submitted for approval consistent with <br /> 48 the following specifications: Multi pair loop detector lead-in cable shall consist of <br /> 49 two or three individually twisted and shielded pairs of#16 AWG stranded copper <br /> 50 wire, surrounded by an outer jacket of polyvinyl chloride (PVC).
