Where existing loop lead-in cable is present, the existing cable shall 33 <br />be pulled out and disposed of. The new lead-in cable shall be spliced to the loop 34 <br />wires utilizing Buchanan splice caps and crimper and a scotch cast epoxy 82-35 <br />B1 splice kit or approved equal as detailed in City Standard Drawings 806A, B 36 <br />and C. Where the wiring schedule in the plans calls for more than one loop 37 <br />detector to be spliced into a single lead-in cable, the loops shall be wired in 38 <br />series. The loop detector lead-in cable shall be pulled into the controller cabinet 39 <br />and connected to the detector channel terminals as indicated in the loop detector 40 <br />schedule in the plans. 41 <br /> 42 <br />Loop Detector Lead-In Cable (2 or 3 pair) 43 <br /> 44 <br />Two or three pair loop detector lead-in cable shall be installed where shown in 45 <br />the wiring schedule in the plans. Belden 1037A and 1055A cables are a pre-46 <br />approved source. Other cables may be submitted for approval consistent with 47 <br />the following specifications: Multi pair loop detector lead-in cable shall consist of 48 <br />two or three individually twisted and shielded pairs of #16 AWG stranded copper 49 <br />wire, surrounded by an outer jacket of polyvinyl chloride (PVC). Each pair shall 50
