Gardtec Eurosec CPX permanent disable

Hello, I have the engineer code and had put the alarm in engineer mode to disable a long time back. Till it started ringing this morning. Reset it with the code and am dreading it will go off again. Please can someone help me with permanently disabling it or putting it back in the engineer or program mode again? The panel currently shows "Enter Code, Check" , and I can't remember how I put it in program mode ages ago. Thank you very much

It's going off again, so sounds like every 60 minutes. Shows battery fault

You need a new battery to stop problem.
2.8/3.2 ah battery
If alarm is not required then totally power down system , mains off to panel and disconnect battery leads the bell should ring outside forv20 minutes then stop.

thank you, i have turned off for now and will ask the installation company for a quote to disable fully, not too confident with the disconnect and the alarm ringing in the building for a longer time.
