UNC-Chapel Hill is not the only school reviewing its campus alert system.
Officials at UNC-Wilmington are also investigating their alert system after it failed to notify students of a July 29 shooting.
Investigators are working to issue a full report detailing the source of the failure by the end of this week, said Cindy Lawson, a spokeswoman for UNC-W in an email.
The shooting, which was non-life threatening, occurred at an apartment complex off campus.
The university notified students by email two hours after the incident occurred but failed to sound the siren and alert students through text messages.
Administrators said these incidents are rare and not due to insufficient testing.
Campus safety officials from UNC-W and UNC-Greensboro said they carry out internal daily testing of their emergency alert systems.
UNC-W’s incident follows the investigation of UNC-CH’s Alert Carolina system after students were not immediately notified of an April armed robbery on campus. Changes to the alert system based on this review are set to be unveiled soon.
System failures at UNC-W are extremely rare, Lawson said.
“During my five-plus year tenure here at UNC-W, we have had only one mechanical failure due to a malfunctioning piece of equipment,” she said. “It was discovered during a routine daily test, not during an emergency situation.”
The most recent failure does not appear to be due to faulty equipment, Lawson said.
