Can I use unshielded for weigand readers

[platestealer]

I am putting access control in a elevator that is 3 stories total. There are extra wires in the hoistway already, but they aren't shielded, can I use these anyways? Will it work?

Maybe too late to answer your situation but I will answer for anyone else researching.

In general almost all readers require untwisted over all shielded 18 or 22 gauge wire. I am aware that Kantech IOProx will allow CAT5E Unshielded Twisted Pair or the wire I previously mentioned. It is always best to consult the manufactures tech information.
