HELP! Followed all instructions to install the alarm panel v2 & interface board to my existing NX-4 panel, when I turned everything on, the 5 of the orange lights (Zone 1-5) on the potentiometers were lit even though I only connected 4 zones... 

I tried adjusting the potentiometers all the way anticlockwise and the lights were still on, so I tried turning it clockwise on Zone 2 and BANG! Sparks  flew from the IC1 chip and it was fried...

Can anyone tell me whether I've done anything incorrectly or is this a manufacturing defect??

  • BTW Zone 5 light seems to stay on no matter whether anything is connected or not, is this supposed to happen!?
