Code change for Concept System alarm

Hi all, I need to change the back up battery in my concept alarm and wondered what was the best way to go about it?

The main control box is in the loft and the keypad is in the kitchen, at the moment I need to use the 0123 code after a power cut so hopefully a new battery in the main control box will fix this. I don't want to set it off and be unable to reset it if there are tamper switches or whatever in the control box so any advice would be gratefully received.

Thanks in advance.

easy one;

press the PROG button
then enter 0123
TAMPER light should show

change battery
put cover back on

press RESET

all done

Great, thanks for the info..will have a look later to see what battery I need.

Hi again,

Prog, 0123 didn't work but Prog and then my code did so all good.

It has a Yucel Y2.1-12 battery and I just wondered what the difference was between that and the NP2.1-12 before I order one?

Thanks again... -)
