Tower electric fences question

you have to be far enough out that a zombie can reach you if you are inside the tower, and the closest to it gets the prompt, so both of you wont get it

 

I activate it everytime i enter the tower,just for "fun"...Never had any problems with it,and actually,i havent even unlocked the electric fence skill yet(campaign 58%)

 

when were you able to activate it?....right from the start of your game? or did you have to do a certain quest first?

 

You just need to be relatively close to the entrance. Then the prompt to use the trap should appear.

You do need to be fairly close though, almost standing on to of the trap, before it will work.

I'm pretty sure that you an use it any time after the quest where they get you to go and activate all of the traps for the night run, which is the first quest in the game.
