The last thing you want to be doing is opening a live unit with little or no information
you need to find the user manual for that particular alarm panel .
The system will need a service,and most likely a replacement battery.
Without the user/engineers manual you will encounter problems you cannot resolve
you need that info in the manual!!
simply opening a panel is dangerous.
simply switching the mains off won't help you most panels have to be worked on whilst live.
Get hold of the manuals first.
Read them and get to know your alarm.
If you encounter any problems,post back on here and the guys can help you.
