Hello, Had an alarm system fitted in my home around 8 years ago. The original installer came last year and serviced it & fitted a new battery in the control box etc. Everything works great. He has since retired and moved away. I’m just about to get an electrician to re-position one of the PIR sensors and I’m wondering how I tell the alarm not to go off when he’s doing the work! I’ve got a Eurosec CP8L keypad and I know the engineers code but could someone tell me the process for putting the system into a sort of ‘maintenance mode’? And then how to get it back to normal service afterwards? Ive read the manuals but I haven’t a clue!
