For your safety, outside entrances are locked minimally at midnight each night and unlocked at 6:30 a.m. You have been issued a key/card to open main doors. Telephones have been placed at each building’s main entrance to allow your visitors to contact you during periods when the doors are locked. Do not prop open outside entrance doors. When locked doors are propped open, hall security is compromised as non-residents are allowed to enter at will. If you see a locked door that has been propped open, close it.
