Addressable Device Circuit Wire Selection Guide
Each 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.
