9200 doesn't arm anymore?
Hi we recently had a power cut for 11 hours. I could hear a strange noise from the alarm box when no power and disconnected the battery. When power was restored I reconnected the battery and although we have a power light and the unit keypad responds when pressed we get no arming noise etc. I bought a new battery but appears no difference although I can see there is no "Day" light on now. Should I attempt a reset to factory settings?
