hi guys, looking for help from a house alarm engineer if possible, i have an ademco vista 10, 8 zone alarm that has got an intermittent fault, when the alarm is unarmed i get the number 99 in the keypad display, can anyone shed any light on this fault. don't know if this is just a coincidence but we had a power outage then this fault occurred. thanks in advance for any help.
