Hi all, I need some help with this unit. I have a 10 yr old NX-8 system w/ a NX 216e expander w/ a total of 24 zones, and 2 NX 1448e key pads.
I had a storm at the end of the summer that took out my system, I have finally gotten around to diagnosing it. The storm left the keypads useless, the back lighting is on but no text. So what I have found so far is one shorted keypad. Initially when I power the unit down then back up (remove wires from AC then reattach) After about 5 sec. It beeps and all goes blank.
So from there I started remove one key pad at a time, after removing one key pad the system comes up and works. However, now the service light is on and the system beeps endlessly. I performed the reset code *7 and it doesn’t react or do anything. I select the service code *2 and get 1, then like the manual says I select 1 again and get 7. Which is” Expander Trouble”
I have also removed the 216e board and performed a reset as well.
So my question is, would expander trouble be the expander board, the remaining key pad or something else? Not sure which way to go from here...
