I am replacing an existing Brinks system. I believe I have everything hooked up correctly and I have 5 zones working fine, but 3 of the binary sensors in my other 3 zones always show up as closed. If I remove the wires from the zone, the sensor shows up as open (at least the icon changes to open). I don't see any end line resistors on either end. I have also tried using a magnet to toggle the sensors on and off and that does not make a difference. I also tried moving the wires to another zone on the other konnected board and it still doesn't work. How else do I go about troubleshooting this?
