Hello all. I recently purchased a 7 year old home that has a built-in alarm system. The previous owner chose to purchase the unit as part of the then-new home's price rather than lease, but when he had the monitoring turned off prior to sale it looks like they locked the board. They used a First Alert FA147c panel and a fixed word keypad. It permanently displays "dl" on the display, which according to the manual means the system is disabled. No notices for zone trips are provided and the motion sensors are shut down. I cycled the power and used both * and # methods to try to retrieve the installer code, but #20 makes the system display "EE" on the keypad.
It appears I'm locked out and the system is permanently disabled. Does anyone have any experience with this board to know if this is the case for sure? If it is locked, what are my options? Can I swap boards with a Vista 10SE and keep my sensors as they are, or do I have to ditch everything and start over? A drop-in FA147c replacement has proven impossible to locate, and even then I'd have to procure a Alpha keypad to program it. I'd just like to be able to use this alarm locally without a monitoring service.
Thanks for your help.
