Hi all

I have a Honeywell galaxy flex in my house but not sure what external sounder it is.
I woke up to the sound of birds today but actually it was my external sounder chirping for some reason. No fault was logged on the control panel so I assume the battery has gone dead in the external box?
I have pulled the fuse on the system now and it's stopped but I don't know how long my 12v battery will last so need to sort it out. The question is can I disable the external siren for the moment so I can turn the rest of the system back on? I have the engineer code.
