Optima Compact G3 Outside bellbox ( Sounder) change

[Viktor Viktor]

Hello everyone,
I hope you’re well.
I have a problem with my Optima Compact Gen 3.
I don’t know how can I change the outside bellbox, sounder without raising the alarm.
If you have any idea please let me know!
Thanks

first, have a body next to the panel. open the bell box. alarm will sound. body at panel enters user code, then you find the battery leads in the bell box and diss (or cut) one of them. ear protection advisable. you can,t avoid the alarm sounding for a few seconds.
