WARREN, NJ - The usual early morning quiet at Watchung Hills was shattered by the sounds of a fire alarm on Thursday. It wasn’t a drill, but also had no apparent cause.

“One of our fire alarms was triggered yesterday morning before school,” said WHRHS superintendent Elizabeth Jewett. “As there was no visible cause we were able to determine, we are currently working with the alarm company to determine the cause as well as if the equipment is functioning as it should be.”
