First Union National Bank of Tennessee has installed a "911" call button at an automated teller machine in Nashville.

The button, which provides instant access to the emergency hot line, was installed in response to an Aug. 25 shooting at the ATM in which a customer was injured.

First Union said two suspects have been arrested and the shooting victim is recovering.

"We're committed to doing everything we can to ensure the safety of our customers," said Ron Samuels, president of the bank's metro region.

The technology will be piloted at six locations in the Southeast to test its effectiveness. First Union said it will use video surveillance to prevent false alarms.
