The fire sprinkler system in a dorm building on West Conn's west side campus was accidentally activated early Sunday morning.  The incident happened on the second floor, east side of Centennial Hall.  University officials say it was caused inadvertently by a resident student. The building was evacuated by the fire department, and within a half hour, West Conn was able to secure critical systems in the building and allow re-occupancy by the students.  Six residential apartments have been impacted by water. Response crews and repair companies were already on scene, and all affected students have been relocated.
