Intermittent power fails may have caused a spike thats blown the internal output fuse on the DC side either to the battery charging circuit or the the main keypad etc. If you want to stop this happening buy a new battery and check the charging voltage to it which should be round 13 volts dc...... The main cause of false alarms is a flat battery........replace it and you should be ok. Dont forget to replace the fuse if need be....should be 1amp or 500 ma.
