Output wires
: AWG24 or AWG 26 are recommended when the load is
powered with current @30mA. This will facilitate the reader closing.
Use the minimum AWG allowed from the table below when the power
is provided by an external power supply and the current is more than
30mA.
*One-volt voltage drop is considered typical.

RS-485 wire
: Cable spec: UL, 24 AWG, 85ohm/Km twisted. Because
the RS-485 is used for door backup line between the two readers
installed on the two sides of the door. Also, the RS-485 is used for
connection of a Voyager device with a Voyager door module installed
on the safe side of the door, where the cable is usually short.
