This is presumably only strictly true if the two batteries have equal charge. Is there a possibility that a discharged battery could result in enough current from the other battery to operate the buzzers? This could either be seen as a b***** nuisance or as a "battery low" indicator (or both, like those smoke detectors that go bleep in the night).
