I used one of the other alarm outputs to control a simple ‘mute’ circuit to stop this tone when the alarm is not sounding. Instead of connecting one side of the loudspeaker to earth, connect it to another alarm output and set that output to be on (and so enabling the speaker), during 1 minute of the bong sounding.
