May I add?.
Identifying the sounder's wiring is all well and good but you won't stop it ringing by removing or linking wires.
See the sounder's are designed to ring when they loose the necessary signals provided by the control panel.We can't tell you how to stop the sounder ringing on here for security reasons,and I hope you can appreciate that.
Gts has told you what to do :)),
No point in getting technical,just let it ring whilst you replace the battery,always a good idea to inform your neighbours of your intentions and carry out the replacement at a sensible time of day.
Don't be fooled into thinking that working on a live panel and fooling with the sounder's wiring either will stop the sounder activating because it won't.
