The Caroline E. Hemenway Harman Continuing Education Building (HECB) on the campus of Brigham Young University (BYU) has a fairly new Notifier system with System Sensor L-Series speaker/strobes playing a slow whoop tone and female voice message. It turned out they were just testing the system unannounced.
