Interrupt Alarm Always Fires?

[Eheran1]

Most likely adding this befor setting the alarm will solve ur problem, since the SQW was still turned on, in ur case at 1Hz. Mine was 8kHz... but after fixing that I found "another" (since this here is technically not one) problem with the library... gonna open it up now...

  // Select output as rate to 1Hz
  clock.setOutput(DS3231_1HZ);
  // Disable SQW-clock 
  clock.enable32kHz(false);
  // Enable output
  //clock.enableOutput(true);
  // Disable output
  clock.enableOutput(false);
