The following chartis based on the following premises:• The entire load is at the end of the wire run (worst case).• Resistance is of solid copper wireContact your local distributor or the factory if further information is needed in your circumstances.Maximum Wire Loop Distance (Feet)Signal Load (A) 18 AWG 16 AWG 14 AWG 12 AWG0.1 1,237 1968 3134 49750.25 495 787 1253 19900.5 247 393 626 9950.75 165 262 417 6631.0 123 196 313 4971.25 99 157 250 3981.5 82 131 208 331Addressable Device Circuit Wire Selection GuideEach addressable device circuit must meet the following requirements:• Total loop resistance - 40 ohm maximum.• Total loop capacitance - 0.28uF maximum (56pF/ft. max.)• Twisted pair wire.• Unshielded cable.• Low capacitance cable.• High velocity of propagation cable - 60% minimum.• Each loop runs separate from all other circuits.• Run + out and - out separately from + in and - in.• Different models or types of cable should not be in the same loop.Maximum Wire Loop Distance (Feet)(Includes all branches of a Style 4 loop)Wire size: 18AWG 16AWG 14AWG * 12AWGWire length: 6150 9750 10,000 10,000Cable length: 3075 4875 5,000 5,000* The terminal blocks of Faraday addressable devices are rated for a maximum of 14AWG wire.
