Ooma and ADT/Ademco LYXNXR
Posted: Mon Jul 25, 2011 11:17 pm
I have ADT monitoring service with an ADEMCO/Honeywell LYXNXR security system. I have wired the alarm to run directly to the hub. When I test the speaker phone at the alarms base unit I get a dial tone. However, every once in a while the alarm starts to beep and I get a FC message (Failure to communicate). Do I need to add the *99 code in? If so does anyone know how to accomplish this? I tried to get some answers from ADT themselves, however, they we not very helpful.
