Hi all,
 
	Another issue with my alarm. On searching on the forum, I understand that a TRBL POWER fault on the DA system Abacus is due to a faulty battery. Just wondering if I remove the cover to find out what battery to get, will all hell break lose? I've not reset the system or set it as I fear the internal sounder will just go off for hours. I just moved into this property and been left with no manuals etc. I have no engineer codes either, just the master code. 
 
	 
 
	I'm assuming that if I undo the cover on the box, a tamper fault will register. Do I just switch the battery and reset the system with the master code? Or is this a job for the professionals? Any advice will be greatly appreciated.
 
	 
 
	thanks in advance,
