I accidently cut the cable to one of the PIR's and reterminated (with alarm going off). I now have aux dc fail showing on the control panel and cannot reset. Have I blown a fuse and if so would this be in the contol panel or in the control unit located nearby? Can this be changed without the alarm activating.

It is a blown fuse and it will be in the main control panel - the alarm will sound when you open the control panel as you will create a tamper fault, but just enter the code to cancel.
