At 3am my alarm sounded(accenta 8 mini) due to a power cut.As result my alarm woke the whole street because i was unable to silence it.The key pad was dead.I dis-connected the battery from the main panel but it still rang.Any ideas? thanks

If the keypad was dead and disconnecting the battery made no difference the battery is also dead. The battery should protect against short term power outage. The bell has its own battery and if the panel supply (mains and battery) is lost it will ring for approx 20 mins. The answer is get a new battery. The cost is about £15.
