Appreciate the pointer here. After verifying with our supplier regarding the Apex Destiny 6100 (which they claim is a Honeywell unit), they suggest it is discontinued with no replacement. I am open to suggesting what ever is known to work well, do you have another recommendation of a model you know to work seamlessly? I tried to drill through the "Add Device Security" menu in the web admin, and couldn't figure out a way to enumerate just panels so I could figure this out on my own.
Thanks so much for the help!
