Hi Arframe2
I know this is an older forum but I have a ISC Challenger I just picked up from a friend. I can take a pick of the firewall if you still need pictures of the firewall? I was wondering if you still have the instructions and if you could email me a copy of the instructions. I have an extra 300 made by ISC and there are much to the instructions, but i thought it would be nice to have them to go with the arc. If you dont have instructions any more but still need pics of fire wall I can still get them for you.
Thanks Bill
